Plain language summary
It is well known that older people are at a higher risk for nutritional inadequacy which is accompanied by depression, impaired cognitive function, and poor overall health. In this secondary analysis of a randomised controlled assessor-blinded dietary intervention trial, the authors examined the effects of six months of nutritional therapy on quality of life, self-rated health, cognitive function, and depression in elderly patients aged 65 years and over. The participants in the intervention group received nutritional therapy (HOMEFOOD) education to overcome malnutrition, which included dietary recommendations to ensure an adequate nutritional intake of energy and protein through diet and additional supplemental protein and energy-rich foods. After six months of nutritional therapy, the intervention group showed improvement in cognitive function, self-rated health, depression score, and quality of life scores, as well as improvements in measures related to weight gain. Further studies need to be conducted in order to determine if nutritional therapy provides additional benefits to older people. However, healthcare professionals can use the results of this study to better understand how nutritional therapy can improve the quality of life and health of older people in comparison to standard care, so they can better advise their patients.
Abstract
BACKGROUND AND AIMS Malnutrition is common among older adults and is related to quality of life, cognitive function, and depression. To what extent nutrition interventions can improve these outcomes remains unclear. The aim of this study was to investigate the effect of nutrition therapy on health-related quality of life (EQ-5D), self-rated health, cognitive function, and depression in community dwelling older adults recently discharged from hospital. METHODS Participants (>65 years) were randomised into an intervention (n = 53) and a control group (n = 53). The intervention group received individualised nutrition therapy based on the nutrition care process including 5 home visits and 3 phone calls, in combination with freely delivered energy- and protein-rich foods and oral nutrition supplements for six months after hospital discharge. EQ-5D, self-rated health, Mini-Mental-State-Examination (MMSE), and the Centre for Epidemiologic Studies Depression - IOWA (CES-D) scale were measured at baseline and at endpoint. RESULTS Two subjects dropped out, one from each arm. The control group experienced an increase in depressive symptoms and a decrease in self-rated health during the study period, while the intervention group experienced increases in cognitive function, self-rated health, and EQ-5D resulting in significant endpoint differences between the groups: EQ-5D (0.102, P = 0.001); self-rated health: 15.876 (P < 0.001); MMSE 1.701 (P < 0.001); depressive symptoms: - 3.072 (P < 0.001); all in favour of the intervention group. Improvements during the intervention in MMSE, self-rated health, and CES-D were significantly related to body weight gain in a linear way. CONCLUSION Cognitive function and mental well-being worsen or stagnate in older adults who receive standard care after hospital discharge. However, a six-month nutrition therapy improves these outcomes leading to statistically and clinically significant endpoint differences between the groups. As improvements were related to body weight gain after hospital discharge, we conclude that the increase in dietary intake, with focus on energy and protein density, and changes in body weight might have contributed to better cognitive function and mental well-being in older adults after the intervention.

Plain language summary
The global spread of COVID-19 and subsequent lockdown measures have presented challenges worldwide. Previous research has highlighted the importance of six key lifestyle behaviours, including diet, physical activity, sleep, sedentary behaviour (including recreational screen time), alcohol use and smoking—collectively referred to as the ‘Big 6’—for the short-term and long-term health of adolescents. The aim of this study was to examine changes in the prevalence of six key chronic disease risk factors from before to during the COVID-19 pandemic, and also to explore whether differences over time are associated with gender and lockdown status. This study is a prospective cohort study among a large and geographically diverse sample of adolescents. The sample included 983 students (girls = 54.8%) from 22 schools. Results show that: - over the 2-year period, the prevalence of excessive recreational screen time, insufficient fruit intake and alcohol and tobacco use increased. - alcohol use increased more among girls compared to boys. - the prevalence of insufficient sleep reduced in the overall sample; yet, increased among girls. - being in lockdown was associated with improvements in sugar-sweetened beverages consumption and discretionary food intake. Authors conclude that supporting young people to improve or maintain their health behaviours, regardless of the course of the pandemic, is important, alongside targeted research and intervention efforts to support groups that may be disproportionately impacted, such as adolescent girls.
Abstract
OBJECTIVE To examine changes in the prevalence of six key chronic disease risk factors (the "Big 6"), from before (2019) to during (2021) the COVID-19 pandemic, among a large and geographically diverse sample of adolescents, and whether differences over time are associated with lockdown status and gender. DESIGN Prospective cohort study. SETTING Three Australian states (New South Wales, Queensland and Western Australia) spanning over 3000 km. PARTICIPANTS 983 adolescents (baseline Mage=12.6, SD=0.5, 54.8% girl) drawn from the control group of the Health4Life Study. PRIMARY OUTCOMES The prevalence of physical inactivity, poor diet (insufficient fruit and vegetable intake, high sugar-sweetened beverage intake, high discretionary food intake), poor sleep, excessive recreational screen time, alcohol use and tobacco use. RESULTS The prevalence of excessive recreational screen time (prevalence ratios (PR)=1.06, 95% CI=1.03 to 1.11), insufficient fruit intake (PR=1.50, 95% CI=1.26 to 1.79), and alcohol (PR=4.34, 95% CI=2.82 to 6.67) and tobacco use (PR=4.05 95% CI=1.86 to 8.84) increased over the 2-year period, with alcohol use increasing more among girls (PR=2.34, 95% CI=1.19 to 4.62). The prevalence of insufficient sleep declined across the full sample (PR=0.74, 95% CI=0.68 to 0.81); however, increased among girls (PR=1.24, 95% CI=1.10 to 1.41). The prevalence of high sugar-sweetened beverage (PR=0.61, 95% CI=0.64 to 0.83) and discretionary food consumption (PR=0.73, 95% CI=0.64 to 0.83) reduced among those subjected to stay-at-home orders, compared with those not in lockdown. CONCLUSION Lifestyle risk behaviours, particularly excessive recreational screen time, poor diet, physical inactivity and poor sleep, are prevalent among adolescents. Young people must be supported to find ways to improve or maintain their health, regardless of the course of the pandemic. Targeted approaches to support groups that may be disproportionately impacted, such as adolescent girls, are needed.

Plain language summary
With an obesogenic environment, unhealthy lifestyle, and accelerating weight gain, obesity is now the most common medical condition in the world. Preconception and pregnancy are priority life stages for healthy lifestyles and obesity prevention with excess weight being associated with adverse pregnancy outcomes, long-term noncommunicable disease in women, and epigenetic consequences across generations. The aim of this study was to evaluate the association of different types of diet and physical activity–based antenatal lifestyle interventions with gestational weight gain (GWG) and maternal and neonatal outcomes. This study is a systematic review and meta-analysis of 28 studies together with 89 studies identified during a previous study. The included studies were randomised controlled trials (which involved 34 546 women) that examined diet (n = 14), physical activity (n = 53), diet with physical activity (n = 19), and mixed interventions (n = 31). Results show that compared with routine care, antenatal diet and physical activity–based lifestyle interventions were associated with reduced GWG. Lifestyle interventions were also associated with lower risk of gestational diabetes and total adverse maternal outcomes. Authors conclude by supporting the integration of structured diet and physical activity interventions alongside routine antenatal care, and the development of policies to improve the health of mothers and their offspring around the world.
Abstract
IMPORTANCE Excessive gestational weight gain (GWG) is common and associated with adverse pregnancy outcomes. Antenatal lifestyle interventions limit GWG; yet benefits of different intervention types and specific maternal and neonatal outcomes are unclear. OBJECTIVE To evaluate the association of different types of diet and physical activity-based antenatal lifestyle interventions with GWG and maternal and neonatal outcomes. DATA SOURCES A 2-stage systematic literature search of MEDLINE, Embase, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, and Health Technology Assessment Database was conducted from February 1, 2017, to May 31, 2020. Search results from the present study were integrated with those from a previous systematic review from 1990 to February 2017. STUDY SELECTION Randomized trials reporting GWG and maternal and neonatal outcomes. DATA EXTRACTION AND SYNTHESIS Data were extracted for random-effects meta-analyses to calculate the summary effect estimates and 95% CIs. MAIN OUTCOMES AND MEASURES Outcomes were clinically prioritized, with mean GWG as the primary outcome. Secondary outcomes included gestational diabetes, hypertensive disorders of pregnancy, cesarean section, preterm delivery, large or small for gestational age neonates, neonatal intensive care unit admission, or fetal death. RESULTS A total of 117 randomized clinical trials of antenatal lifestyle interventions (involving 34 546 women) were included. Overall lifestyle intervention was associated with reduced GWG (-1.15 kg; 95% CI, -1.40 to -0.91), risk of gestational diabetes (odds ratio [OR], 0.79; 95% CI, 0.70-0.89), and total adverse maternal outcomes (OR, 0.89; 95% CI, 0.84-0.94) vs routine care. Compared with routine care, diet was associated with less GWG (-2.63 kg; 95% CI, -3.87 to -1.40) than physical activity (-1.04 kg; 95% CI, -1.33 to -0.74) or mixed interventions (eg, unstructured lifestyle support, written information with weight monitoring, or behavioral support alone) (-0.74 kg; 95% CI, -1.06 to -0.43). Diet was associated with reduced risk of gestational diabetes (OR, 0.61; 95% CI, 0.45-0.82), preterm delivery (OR, 0.43; 95% CI, 0.22-0.84), large for gestational age neonate (OR, 0.19; 95% CI, 0.08-0.47), neonatal intensive care admission (OR, 0.68; 95% CI, 0.48-0.95), and total adverse maternal (OR, 0.75; 95% CI, 0.61-0.92) and neonatal outcomes (OR, 0.44; 95% CI, 0.26-0.72). Physical activity was associated with reduced GWG and reduced risk of gestational diabetes (OR, 0.60; 95% CI, 0.47-0.75), hypertensive disorders (OR, 0.66; 95% CI, 0.48-0.90), cesarean section (OR, 0.85; 95% CI, 0.75-0.95), and total adverse maternal outcomes (OR, 0.78; 95% CI, 0.71-0.86). Diet with physical activity was associated with reduced GWG (-1.35 kg; 95% CI, -1.95 to -0.75) and reduced risk of gestational diabetes (OR, 0.72; 95% CI, 0.54-0.96) and total adverse maternal outcomes (OR, 0.81; 95% CI, 0.69-0.95). Mixed interventions were associated with reduced GWG only. CONCLUSIONS AND RELEVANCE This systematic review and meta-analysis found level 1 evidence that antenatal structured diet and physical activity-based lifestyle interventions were associated with reduced GWG and lower risk of adverse maternal and neonatal outcomes. The findings support the implementation of such interventions in routine antenatal care and policy around the world.

Plain language summary
Non-alcoholic fatty liver disease (NAFLD) is characterised by fat accumulation in the liver that can result in liver damage. NAFLD affects approximately 25% of the global population. There is evidence that dietary polyphenols can improve metabolism and insulin resistance and reduce inflammation and oxidative stress, which are the mechanisms that lead to liver damage in NAFLD. This systematic review and meta-analysis aimed to assess the effectiveness of dietary polyphenols in the treatment of non-alcoholic fatty liver disease (NAFLD). Eight dietary polyphenols, such as curcumin, resveratrol, naringenin, anthocyanin, hesperidin, catechin, silymarin, and genistein, were evaluated for their efficacy and safety. The administration of 80-3,000 mg of Curcumin for an 8-12 week duration is effective and safe for reducing body mass index, aspartate aminotransferase (AST), alanine aminotransferase (ALT), triglycerides (TG), total cholesterol (TC), and insulin resistance (HOMA-IR). Compared with the placebo, Naringenin reduced the percentage of NAFLD grade, TG, TC, and low-density lipoprotein cholesterol and increased high-density lipoprotein cholesterol. Hesperidin may potentially decrease body mass index (BMI), AST, ALT, TG, TC, and HOMA-IR. Catechin is safe, and 500-1000 mg supplementation for 12 weeks may reduce BMI, HOMA-IR, and TG. NAFLD patients who received silymarin showed improvements in ALT and AST, as well as reductions in hepatic fat accumulation and liver stiffness. 94–2100 mg of Silymarin supplementation for 8–48 weeks may reduce liver enzyme levels. Researchers can use the results of this study to understand the clinical utility of different polyphenol supplements in the treatment of NAFLD. Because the current evidence is highly heterogeneous in nature and limited in scope, further robust research is required on various classes of polyphenols and their effectiveness in reducing the severity of NAFLD.
Abstract
Background: Dietary polyphenol treatment of non-alcoholic fatty liver disease (NAFLD) is a novel direction, and the existing clinical studies have little effective evidence for its therapeutic effect, and some studies have inconsistent results. The effectiveness of dietary polyphenols in the treatment of NAFLD is still controversial. The aim of this study was to evaluate the therapeutic efficacy of oral dietary polyphenols in patients with NAFLD. Methods: The literature (both Chinese and English) published before 30 April 2022 in PubMed, Cochrane, Medline, CNKI, and other databases on the treatment of NAFLD with dietary polyphenols was searched. Manual screening, quality assessment, and data extraction of search results were conducted strictly according to the inclusion and exclusion criteria. RevMan 5.3 software was used to perform the meta-analysis. Results: The RCTs included in this study involved dietary supplementation with eight polyphenols (curcumin, resveratrol, naringenin, anthocyanin, hesperidin, catechin, silymarin, and genistein) and 2,173 participants. This systematic review and meta-analysis found that 1) curcumin may decrease body mass index (BMI), Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), Triglycerides (TG) total cholesterol (TC), and Homeostasis Model Assessment-Insulin Resistance (HOMA-IR) compared to placebo; and curcumin does not increase the occurrence of adverse events. 2) Although the meta-analysis results of all randomized controlled trials (RCTs) did not reveal significant positive changes, individual RCTs showed meaningful results. 3) Naringenin significantly decreased the percentage of NAFLD grade, TG, TC, and low-density lipoprotein cholesterol (LDL-C) and increased high-density lipoprotein cholesterol (HDL-C) but had no significant effect on AST and ALT, and it is a safe supplementation. 4) Only one team presents a protocol about anthocyanin (from Cornus mas L. fruit extract) in the treatment of NAFLD. 5) Hesperidin may decrease BMI, AST, ALT, TG, TC, HOMA-IR, and so on. 6) Catechin may decrease BMI, HOMA-IR, and TG level, and it was well tolerated by the patients. 7) Silymarin was effective in improving ALT and AST and reducing hepatic fat accumulation and liver stiffness in NAFLD patients. Conclusion: Based on current evidence, curcumin can reduce BMI, TG, TC, liver enzymes, and insulin resistance; catechin can reduce BMI, insulin resistance, and TG effectively; silymarin can reduce liver enzymes. For resveratrol, naringenin, anthocyanin, hesperidin, and catechin, more RCTs are needed to further evaluate their efficacy and safety.

Allergic diseases, including atopic dermatitis (AD), are serious conditions that disrupt the quality of life of affected individuals. AD is a chronic inflammatory skin disease that is relapsing and whose onset is generally related to a patient’s or family’s atopic history such as asthma and allergic rhinitis. The aim of this study was to assess randomized control trials based on the PICO strategy—population = adult with AD; intervention = probiotic intervention; control = standard therapy; and outcome = clinical manifestations (Scoring Atopic Dermatitis index (SCORAD) evaluation, skin severity, itch severity), quality of life, and/or immune response. This study is a systematic review of six randomised controlled trials involving a total of 241 subjects, including 128 subjects in the probiotics group and 113 subjects in the placebo group. Results show that probiotic supplementation may have the potential to decrease disease severity (SCORAD) in adult AD. Therefore, decrease in disease severity may also improve the quality of life. Authors conclude that based on their findings, probiotics can be used as adjuvant treatment of adult AD.
Abstract
BACKGROUND Atopic dermatitis (AD) is chronic inflammatory skin disease that is relapsing and a serious condition that disrupts the quality of life of affected individuals. Probiotics are an immunomodulator that can enhance the immune control of atopic dermatitis. METHODS All randomized controlled trials of probiotics for the treatment of adult AD published before December 2020 were included in this study from the PubMed databases and manual searching. RESULTS Six randomized controlled trials (n = 241) were selected for this meta-analysis study. Probiotics were effective in treating adult patients with AD, indicated by the decrease in Scoring Atopic Dermatitis/SCORAD (Mean Difference (MD) - 7.90, 95% CI - 7.25 to - 6.92; p < 0.00001; I2 = 96%) and improved quality of life (MD - 7.68, 95% CI - 14.08 to - 1.29; p = 0.02; I2 = 47%) which were statistically significant. However, skin severity, itch severity, Dermatology Life Quality Index (DLQI), IL-4, TFN-γ, and IgE showed no significant difference in this meta-analysis study (p > 0.05). LIMITATIONS The study found no available data for side effects of probiotics. STRENGTH This meta-analysis analyzed a total of 241 AD patients of Asian and European origin. CONCLUSION The use of probiotics decreased SCORAD significantly in adult patients with AD. Probiotics can improve the quality of life of patients with AD. The use of probiotics in atopic dermatitis has been widely studied, with controversial results. This meta-analysis suggests that the use of probiotics can improve SCORAD and the quality of life of patients with atopic dermatitis.

Allium vegetables, such as garlic, onion, and leeks, are characterized by a high content of organosulfur compounds, flavonoids, glutathione, selenium compounds, and vitamins E and C. The aim of this study was to clarify the role of Allium vegetables in non-digestive tract cancer. This study is a systematic review and meta-analysis of 5 studies (11 cohort and 14 case-control studies) on Allium vegetables involving 18,070 patients. Results showed that Allium vegetable consumption could reduce the risk of non-digestive tract cancer demonstrating the protective role of Allium vegetables. Authors conclude that further randomized controlled trials or well-designed cohort studies with high quality are needed to further confirm the findings of this study.
Abstract
PURPOSE To clarify the role of Allium vegetables in non-digestive tract cancer, we conducted this meta-analysis. METHODS Following Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, we conducted a meta-analysis of published studies assessing the associations between Allium vegetables and the risk of non-digestive tract cancer. We estimated the pooled odds ratio (OR) of non-digestive tract cancer for the highest and lowest Allium vegetable consumption using random-effects models. A dose-response regression model was used to evaluate the relationship between Allium vegetables and non-digestive tract cancer risk. RESULTS In a pooled analysis of 25 studies (11 cohort and 14 case-control studies) on Allium vegetables, a total of 18,070 patients with non-digestive tract cancer were finally included. Integrated OR of non-digestive tract cancer was 0.86 [95% confidence interval (CI):0.80-0.93] for the highest versus the lowest Allium vegetable consumption for all studies, 0.78 (95% CI:0.69-0.90) for case-control studies and 0.94 (95%CI: 0.87-1.02) for cohort studies. Sensitivity analysis showed that the pooled effect was stable. No apparent publication bias was identified in this study; however, the cumulative meta-analysis suggested that studies conducted earlier (from 1994 to 1997) might be a source of heterogeneity. Dose-response regression model indicated that Allium vegetable consumption was associated with the risk of non-digestive tract cancer (P = 0.001 for non-linearity; P = 0.032 for linearity). CONCLUSION Higher Allium vegetable consumption could reduce the risk of non-digestive tract cancers, demonstrating the protective role of Allium vegetables.

Allergic rhinitis (AR) is characterized by a nasal sensitive inflammation. Common symptoms of AR are nasal itching, sneezing, rhinorrhoea, and nasal congestion. In addition, some patients experience symptoms of allergic rhinoconjunctivitis, such as watery or itchy or red eyes. The aim of this study was to address the effect and safety of probiotics on AR and to explore the possible causes of between-study heterogeneity via subgroup. This study is a systematic review and meta-analysis of twenty-eight randomised controlled trials. Results showed that probiotics supplementation for patients with AR can ameliorate AR symptoms and improve the quality of life. Probiotics supplementation can correct the T helper cell 1/ T helper cell 2 balance. Furthermore, there was no significant change in overall or antigen-specific immunoglobulin E levels between probiotic-treated and placebo-treated subjects. Authors conclude that in spite of the positive results of some outcomes, there is weak evidence that probiotics have a potential benefit in the treatment of AR.
Abstract
Background: Probiotics have proven beneficial in a number of immune-mediated and allergic diseases. Several human studies have evaluated the efficacy and safety of probiotics in allergic rhinitis; however, evidence for their use has yet to be firmly established. Objective: We undertook a systematic review and meta-analysis aiming to address the effect and safety of probiotics on allergic rhinitis. Methods: We systematically searched databases [MEDLINE (PubMed), Embase, and the Cochrane Central Register of Controlled Trials] from inception until June 1, 2021. Qualified literature was selected according to inclusion and exclusion criteria, the data were extracted, and a systematic review and meta-analysis was conducted. Results: Twenty-eight studies were included. The results showed that probiotics significantly relieved allergic rhinitis symptoms (standardized mean difference [SMD], -0.29, 95% confidence interval (CI) [-0.44, -0.13]; p = 0.0003, I 2 = 89%), decreased Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) scores compared with the control group (SMD, -0.64, 95% CI [-0.79, -0.49], p < 0.00001, I 2 = 97%), and increased T helper cell 1(Th1)/Th2 ratio (mean difference [MD], -2.47, 95% CI [-3.27, -1.68], p < 0.00001, I 2 = 72%). There was no significant change in overall or specific IgE levels between probiotic-treated and placebo-treated subjects (SMD, 0.09, 95% CI [-0.16, 0.34], I 2 = 0%, and SMD, -0.03, 95% CI [-0.18, 0.13], p = 0.72, I 2 = 0%, respectively). Conclusions: To sum up, probiotic supplement seems to be effective in ameliorating allergic rhinitis symptoms and improving the quality of life, but there is high heterogeneity in some results after subgroup analysis and clinicians should be cautious when recommending probiotics in treating allergic rhinitis.

Plain language summary
Older people are at high risk of cardiovascular disease, and 90% of the risk factors can be modified, including an unhealthy diet, poor physical activity, obesity, smoking, and obesity-related comorbidities. This randomised controlled trial examined a multifactorial approach combining several lifestyle modifications in 1259 older adults between 60 and 77 years of age to reduce the risk of cardiovascular disease. Participants were randomly assigned to intensive multi-domain lifestyle intervention or regular health advice control groups. The multifactorial lifestyle intervention incorporated dietary counselling, exercise training, cognitive training, and managing CVD and metabolic risk factors. Dietary interventions included tailored strategies that considered increased consumption of fruits, berries, vegetables, whole grains, margarine, oil, and fish. Physical exercise interventions included strength training, balance exercises, and aerobic exercises. Cognitive interventions and intensive strategies to manage metabolic factors were also implemented. In the multifactorial lifestyle intervention group, cerebrovascular events were lower after two years than in the control group. In addition, cardiovascular disease and stroke incidence were lower in the elderly with a history of cardiovascular disease. Healthcare professionals can use the results from this study to understand the benefits of multifactorial lifestyle interventions on cardiovascular disease. However, there is a need for longer-term robust studies since the evidence is sparse.
Abstract
AIMS: Joint prevention of cardiovascular disease (CVD) and dementia could reduce the burden of both conditions. The Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER) demonstrated a beneficial effect on cognition (primary outcome) and we assessed the effect of this lifestyle intervention on incident CVD (pre-specified secondary outcome). METHODS AND RESULTS FINGER enrolled 1259 individuals aged 60-77 years (ClinicalTrials.gov NCT01041989). They were randomized (1:1) to a 2-year multi-domain intervention with diet, physical and cognitive activity, and vascular monitoring (n = 631), or general health advice (n = 628). National registries provided data on CVD including stroke, transient ischaemic attack (TIA), or coronary heart event. During an average of 7.4 years, 229 participants (18%) had at least one CVD diagnosis: 107 in the intervention group and 122 in the control group. The incidence of cerebrovascular events was lower in the intervention than the control group: hazard ratio (HR) for combined stroke/TIA was 0.71 [95% confidence interval (CI): 0.51-0.99] after adjusting for background characteristics. Hazard ratio for coronary events was 0.84 (CI: 0.56-1.26) and total CVD events 0.80 (95% CI: 0.61-1.04). Among those with history of CVD (n = 145), the incidence of both total CVD events (HR: 0.50, 95% CI: 0.28-0.90) and stroke/TIA (HR: 0.40, 95% CI: 0.20-0.81) was lower in the intervention than the control group. CONCLUSION A 2-year multi-domain lifestyle intervention among older adults was effective in preventing cerebrovascular events and also total CVD events among those who had history of CVD.

Plain language summary
Children with chronic diseases are more likely to suffer emotional-behavioural problems than healthy children, which can also impact the family. Sandplay has successfully been used as a therapy in children with autism spectrum disorder and this randomised control trial aimed to determine the effect of sandplay therapy in 62 children with chronic diseases and their caregivers. The results showed that sandplay reduced anxiety, depression, withdrawal and social behavioural problems and improved behaviour in children with chronic diseases. Depression and anxiety were also improved in the caregivers of those children who participated in sandplay. It was concluded that sandplay therapy is an effective clinical tool to improve several psychological domains in children with chronic diseases.
Abstract
PURPOSE Children with chronic diseases exhibit a higher incidence of emotional-behavioural problems. Though sandplay therapy is a universally recognized psychological treatment method, experimental evidence for this form of therapy is lacking. Our aims were to examine the effectiveness of sandplay therapy in reducing emotional and behavioural problems in school-age children with chronic diseases as well as anxiety and depression in their caregivers. DESIGN AND METHODS A total of 60 children and their caregivers were enrolled in the present study between January and October 2019. A randomized controlled trial was conducted at the Children's Hospital of Chongqing Medical University, China. Participants were divided into an intervention and a control group. Both groups received regular treatment, and the intervention group received additional sandplay therapy. Four behavioural rating scales were used to evaluate the differences between the two groups. The children's scores on the Child Behavior Checklist (CBCL), Eysenck Personality Questionnaire (EPQ), Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) before and after the intervention were compared using the Mann-Whitney test. The Wilcoxon signed rank test was also employed to compare the median results before and after treatment. RESULTS The total scores for CBCL, anxiety and depression, withdrawal, and social behavioural problems for children in the intervention group were all lower than the corresponding scores for those in the control group (p < .05). The EPQ scores for emotional stability and psychosis in the intervention group were both lower than those in the control group (p < .05). The SAS and SDS scores for the caregivers of children in the intervention group were also lower than the corresponding scores for those in the control group (p < .05). CONCLUSION Sandplay therapy can reduce anxiety, withdrawal, and social behavioural problems in school-age children with chronic diseases, as well as relieve anxiety and depression symptoms in their caregivers. Our study provided evidence for the clinical application of sandplay therapy and highlights the importance of offering and integrating psychological treatment in clinical nursing care.

Plain language summary
Diets high in meat and cheese, which are acidogenic and low in fruits and vegetables, which are alkalising, increase the dietary acid load (DAL) of the diet. Diets with a high DAL have been associated with poor health outcomes and the development of heart disease and type 2 diabetes. Plant-based diets have been associated with a lower DAL, however very little research exists on this. Individuals following a vegan diet have been shown in previous studies to have a reduced DAL, however it is unclear whether this was due to a reduced calorie intake or because of the diet composition. This post-hoc study aimed to investigate this and determine whether eating a vegan diet for 4-weeks reduced DAL and how this compares to 4-weeks of a diet rich in meat. The results showed that after 3-weeks, the vegan diet significantly reduced the DAL compared to the meat-rich diet, which increased the DAL. Interestingly all the participants in this study were put on the same balanced diet for 7 days prior to commencing the trial, reducing the chance that results would be affected by a prior diet. It was concluded that a vegan diet as opposed to a meat-rich diet may be of benefit to health outcomes through lowering DAL. This study could be used by healthcare professionals to understand that a balanced vegan diet may be of benefit to those who have heart disease and/or type 2 diabetes. However as this trial did not measure indicators of type 2 diabetes or heart disease, these associations are speculative.
Abstract
The composition of diet strongly affects acid-base homeostasis. Western diets abundant in acidogenic foods (meat and cheese) and deficient in alkalizing foods (fruits and vegetables) increase dietary acid load (DAL). A high DAL has been associated with numerous health repercussions, including cardiovascular disease and type-2-diabetes. Plant-based diets have been associated with a lower DAL; however, the number of trials exploring this association is limited. This randomized-controlled trial sought to examine whether an isocaloric vegan diet lowers DAL as compared to a meat-rich diet. Forty-five omnivorous individuals were randomly assigned to a vegan diet (n = 23) or a meat-rich diet (n = 22) for 4 weeks. DAL was determined using potential renal acid load (PRAL) and net endogenous acid production (NEAP) scores at baseline and after 3 and 4 weeks, respectively. After 3 weeks, median PRAL (-23.57 (23.87)) and mean NEAPR (12.85 ± 19.71) scores were significantly lower in the vegan group than in the meat-rich group (PRAL: 18.78 (21.04) and NEAPR 60.93 ± 15.51, respectively). Effects were mediated by a lower phosphorus and protein intake in the vegan group. Our study suggests that a vegan diet is a potential means to reduce DAL, whereas a meat-rich diet substantially increases the DAL burden.
