Abstract
PURPOSE This study aimed to examine the effects of an eight-session structured urban forest healing program for cancer survivors with fatigue. BACKGROUND Cancer-related fatigue (CRF) is a complex and multifactorial common symptom among cancer survivors that limits quality of life (QoL). Although health benefits of forest healing on physiological, physical, and psychological aspect as well as on the immune system have been reported in many studies, there is limited evidence on the efficacy of specialized forest program for cancer survivors. METHOD A single-blinded, pre-test and post-test control group clinical trial was conducted with -75 cancer survivors assigned to either the forest healing group or the control group. The intervention was an eight-session structured urban forest program provided at two urban forests with easy accessibility. Each session consists of three or four major activities based on six forest healing elements such as landscape, phytoncides, anions, sounds, sunlight, and oxygen. Complete data of the treatment-adherent sample (≥ 6 sessions) was used to examine whether sociodemographic, clinical, physiological (respiratory function, muscle strength, balance, 6-min walking test) and psychological (distress, mood state, sleep quality, QoL) characteristics at baseline moderated the intervention effect on fatigue severity at 9 weeks. RESULTS Significant time-group interactions were observed muscle strength, balance, 6-min walking test, distress, fatigue, moods, and QoL. The mean difference in fatigue between pre- and post-forest healing program was 9.1 (95% CI 6.2 to 11.9), 11.9 (95% CI 7.6 to 16.1) in moods, and -93.9 (95% CI -123.9 to -64.0) in QoL, showing significant improvements in forest healing group, but no significant improvements in the control group. CONCLUSION This study suggests that a forest healing program positively impacts the lives of cancer survivors, by addressing both physical and psychological challenges associated with CRF.

Hypertension (HTN) is a complex and modifiable risk factor for cardiovascular diseases (CVDs) and stroke, while a diverse range of endogenous and environmental factors contribute to both HTN onset and progression. The adult gut microbiota (GM) consists of trillions of microorganisms and maintains the gut immunity and whole-body homeostasis. The aim of this study was to investigate the GM characteristics in HTN subjects in Northwestern China, and evaluate the associations of GM with blood pressure levels based on sex differences. This study was a cross-sectional study. Participants were randomly selected for the HTN and control groups. A total of 36 HTN subjects (24 females and 12 males) and 18 controls (9 females and 9 males) were randomly selected for metagenomic analysis. Results showed a positive association between GM characteristics and alterations and HTN in both females and males. Thus, GM dysbiosis underlies HTN pathogenesis. Authors conclude that further studies are needed to elucidate the underlying mechanisms and potential therapeutic interventions targeting GM for HTN prevention and management
Abstract
BACKGROUND The human gut microbiota (GM) is involved in the pathogenesis of hypertension (HTN), and could be affected by various factors, including sex and geography. However, available data directly linking GM to HTN based on sex differences are limited. METHODS This study investigated the GM characteristics in HTN subjects in Northwestern China, and evaluate the associations of GM with blood pressure levels based on sex differences. A total of 87 HTN subjects and 45 controls were recruited with demographic and clinical characteristics documented. Fecal samples were collected for 16S rRNA gene sequencing and metagenomic sequencing. RESULTS GM diversity was observed higher in females compared to males, and principal coordinate analysis showed an obvious segregation of females and males. Four predominant phyla of fecal GM included Firmicutes, Bacteroidetes, Actinobacteria and Proteobacteria. LEfSe analysis indicated that phylum unidentified_Bacteria was enriched in HTN females, while Leuconostocaceae, Weissella and Weissella_cibaria were enriched in control females (P < 0.05). Functionally, ROC analysis revealed that Cellular Processes (0.796, 95% CI 0.620 ~ 0.916), Human Diseases (0.773, 95% CI 0.595 ~ 0.900), Signal transduction (0.806, 95% CI 0.631 ~ 0.922) and Two-component system (0.806, 95% CI 0.631 ~ 0.922) could differentiate HTN females as effective functional classifiers, which were also positively correlated with systolic blood pressure levels. CONCLUSIONS This work provides evidence of fecal GM characteristics in HTN females and males in a northwestern Chinese population, further supporting the notion that GM dysbiosis may participate in the pathogenesis of HTN, and the role of sex differences should be considered.

Plain language summary
Aging is associated with a decline in physiological and physical function resulting in reduced physical activity, all of which are driving factors to the onset of chronic diseases and physical impairment. Older adults are often deficient in micronutrients, specifically vitamin D, which has been shown to have detrimental effects on the immune system, inflammatory and healing processes of fractured bones and also cardiovascular health beyond other musculoskeletal effects. The aim of this study was to investigate the effect of different vitamin D regimens in older individuals during an ongoing strength training period of 10 weeks while receiving vitamin D supplementation at the recommended level of 800 IU per day vs. a single dose of 50.000 IU per month. The data presented in this paper are part of the NutriAging Vitamin D study. The study was a randomised placebo-controlled double-blind trial which recruited one hundred community-dwelling women and men (aged 65–85 years). Participants were randomly allocated into three intervention groups, either the control group, the vitamin D daily (VDD) or the vitamin D monthly group (VDM). Results showed that oxidative stress might have played a role in the detrimental progress on chromosomal stability parameters since the protective effect of GSH (reduced glutathione) was reduced in all study groups at the end of the intervention, but the least reduction occurred in the VDD group. Authors concluded that a supplementation with the recommended dose of 800 IU vitamin D per day might be more advantageous when it comes to chromosomal stability parameters in older, formerly untrained participants undergoing demanding resistance exercise for 10 weeks.
Abstract
Older adults lack of proper physical activity which is often accompanied by vitamin D deficiency. Those factors are known to contribute to health issues in the later years of life. The main goal of this intervention study was to investigate the effect of different vitamin D supplementation strategies for 4 weeks solely or combined with a 10-week strength training program on chromosomal stability in peripheral blood mononuclear cells in community-dwelling older people. One hundred women and men (65-85 years) received either vitamin D3 daily (800 IU), a monthly dose (50.000 IU) or placebo for 17 weeks. All groups received 400 mg calcium daily. The fitness status of the study participants was measured using the 30- second chair stand test, the handgrip strength test and the 6-min walk test. The cytokinesis block micronucleus cytome (CBMN) assay was applied to analyze chromosomal anomalies, including cytotoxic and genotoxic parameters. Changes in antioxidant markers were measured in plasma. Walking distance and chair stand performance improved significantly. Increased levels of the parameters of the CBMN assay were detected for all intervention groups at study end. At baseline micronuclei (MNi) frequency correlated significantly with BMI in both sexes (females: r = 0.369, p = 0.034; males: r = 0.265, p = 0.035), but not with vitamin D serum levels. In females, body fat (r = 0.372, p < 0.001) and functional parameter using the 30-s chair stand test (r = 0.311, p = 0.002) correlated significantly with MNi frequency. Interestingly, not vitamin D supplementation but 10 weeks of resistance training increased MNi frequency indicating elevated chromosomal instability and also adverse effects on antioxidant markers including glutathione and FRAP were detected in the group of community-dwelling older adults.

Abstract
IMPORTANCE Mismatch repair deficiency (dMMR) occurs in various cancers, and these tumors are attractive candidates for anti-programmed cell death 1 therapies, such as dostarlimab, a recently approved immune checkpoint inhibitor. OBJECTIVE To assess the antitumor activity and safety of dostarlimab in patients with advanced or recurrent dMMR solid tumors. DESIGN, SETTING, AND PARTICIPANTS The GARNET trial was a phase 1, open-label, single-group, multicenter study that began enrolling May 8, 2017. Participants had advanced or recurrent dMMR and microsatellite instability-high (MSI-H) or polymerase epsilon (POLE)-altered solid tumors. The data cut for this interim analysis was from November 1, 2021, with median follow-up of 27.7 months. INTERVENTIONS Patients received 500 mg of dostarlimab intravenously every 3 weeks for 4 doses, then 1000 mg every 6 weeks until disease progression, discontinuation, or withdrawal. MAIN OUTCOMES AND MEASURES The primary objective was to evaluate objective response rate and duration of response in patients with dMMR solid tumors by blinded independent central review using Response Evaluation Criteria in Solid Tumors, version 1.1. RESULTS The efficacy population included 327 patients (median [range] age, 63 [24-85] years; 235 [71.9%] female; 7 [2.1%] Asian, 6 [1.8%] Black, and 206 [63.0%] White patients), with 141 patients (43.1%) with dMMR endometrial cancer, 105 patients (32.1%) with dMMR colorectal cancer, and 81 patients (24.8%) with other dMMR tumor types. All patients had at least 1 previous line of therapy. Objective response rate assessed per blinded independent central review for dMMR solid tumors was 44.0% (95% CI, 38.6% to 49.6%). Median duration of response was not reached (range, ≥1.18 to ≥47.21 months); 72.2% of responders (104 of 144) had a response lasting 12 or more months. Median progression-free survival was 6.9 months (95% CI, 4.2 to 13.6 months); probability of progression-free survival at 24 months was 40.6% (95% CI, 35.0% to 46.1%). Median overall survival was not reached (95% CI, 31.6 months to not reached). The most frequent immune-related adverse events were hypothyroidism (25 [6.9%]), alanine aminotransferase increase (21 [5.8%]), and arthralgia (17 [4.7%]). No new safety concerns were identified. CONCLUSIONS AND RELEVANCE In this nonrandomized controlled trial, dostarlimab was a well-tolerated treatment option with rapid, robust, and durable antitumor activity in patients with diverse dMMR solid tumors. These findings suggest that dostarlimab provides meaningful long-term benefit in a population with high unmet need. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02715284.

Abstract
BACKGROUND To explore the curative effect of Shuangshen Decoction combined with immunological preparations in the treatment of pediatric nephrotic syndrome and its influence on concurrent infection and recurrence rate. METHODS Ninety children with nephrotic syndrome were divided into the routine group and the combined group. The routine group received conventional treatment and immune agents, and the combined group was treated with Shuangshen Decoction on the basis of the routine group. The clinical indexes of the two groups were analyzed and followed up. The infection rate and recurrence rate were calculated. RESULTS The TCM syndrome scores in the combined group were significantly lower than those in the routine group. The total effective rate of the combined group was significantly higher than that of the routine group. The recurrence rate and infection rate of the combined group were significantly lower than those of the routine group. The incidence of adverse reactions in the combined group was significantly lower than that in the routine group. CONCLUSION Shuangshen Decoction combined with immune preparations is effective in treating pediatric nephrotic syndrome and can reduce the incidence of adverse reactions, infection rate, and recurrence rate.

Abstract
BACKGROUND Non-AIDS-associated chronic diseases in HIV+ patients have been on the rise since the advent of antiretroviral therapy. Especially cardiovascular diseases and disruption in the gastrointestinal tract have limited health-related quality of life (QoL). Several of those complications have been associated with chronic systemic inflammation. Short-chain fatty acids (SCFA), with propionate as one of the major compounds, have been described as an important link between gut microbiota and the immune system, defining the pro- and the anti-inflammatory milieu through direct and indirect regulation of T-cell homeostasis. The effects of dietary supplementation of sodium propionate (SP) in people living with HIV (PLHIV) have not yet been investigated prior to this study. OBJECTIVES To investigate the impact of SP uptake among PLHIV and its relevance to improve QoL, the study aimed to investigate metabolic, immunological, microbiome and patient-reported QoL-related changes post-SP supplementation with follow-up. METHODS A prospective, non-randomized, controlled, monocentric interventional study was conducted in WIR, Center for Sexual Health and Medicine, in Bochum, Germany. 32 HIV+ patients with unaltered ART-regimen in the last three months were included. Participants were given SP for a duration of 12 weeks in the form of daily oral supplementation and were additionally followed-up for another 12 weeks. RESULTS The supplementation of SP was well tolerated. We found an improvement in lipid profiles and long-term blood glucose levels. A decrease in pro-inflammatory cytokines and a depletion of effector T cells was observed. Regulatory T cells and IL-10 decreased. Furthermore, changes in taxonomic composition of the microbiome during follow-up were observed and improvement of items of self-reported life-quality assessment. CONCLUSION Taken together, the beneficial impact of SP in PLHIV reflects its potential in improving metabolic parameters and modulating pro-inflammatory immune responses. Thus, possibly reducing the risk of cardiovascular disorders and facilitating long-term improvement of the gut flora.

Journal of integrative and complementary medicine. 2022;(9):749-756
Abstract
Highlights Home-based hydrotherapy leads to fewer missed kindergarten-days in total. In the application group, more fever days could be registered. Hydrotherapy, according to the hormesis principle by Sebastian Kneipp, aims to reduce infections of the lower respiratory tract. Parents participation motivated by increase in applicable health knowledge for their children. Objectives: This study investigates the effect of cold-water hydrotherapy stimulation according to the hormesis principle by Sebastian Kneipp on the number of missing kindergarten-days, fever days, and respiratory tract infections in children aged 3-6 years. Study design: A nonrandomized, controlled, explorative, mixed-methods clinical study. Intervention: The hydrotherapeutic intervention treated children aged 3-6 years with Kneipp arm affusions over 6 weeks. The control group received no intervention. Number of missed kindergarten-days, fever days, and respiratory tract infections were assessed by means of a digital diary. Through a self-developed structured questionnaire, sociodemographic data of both groups were compared and reason for participation in the study was recorded and qualitatively evaluated. Results: Twenty children participants and their parents in the intervention group and 18 in the control group were evaluated. The intervention was conducted at home by the parents. Statistical analysis revealed no significant differences between the groups but still showed intermediate effect sizes (indicating an underpowered study). These effect sizes point to a potentially lower proportion of children in the application group versus the control group with missed kindergarten-days in total (d = 0.67), days missed due to fever (d = 0.29), and infections of the lower respiratory tract (d = 0.60). In a future study, these parameters will thus serve as promising factors for evaluation. Parent's stated reasons for participation interest were to improve health, increase their own health knowledge, and because of their interest in alternative therapies and to support research. Conclusions: Cold-water hydrotherapy stimulation, according to the hormesis principle by Sebastian Kneipp, did reduce the number of days absent in kindergarten in total in the intervention group and lower respiratory tract infections occurred less frequently. Parent' participation interest demonstrated a desire to increase health literacy and implement this with their own children. Due to the small sample size, the results should be interpreted cautiously. Clinical Trial Registration Number: German Register of Clinical Trials (DRKS): ID 00017562.

Abstract
To explore the effects of nutritional support combined with insulin therapy on serum protein, procalcitonin (PCT), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), pentraxin-3 (PTX-3), and serum amylase (AMS) levels in patients with diabetic ketoacidosis complicated with acute pancreatitis.A total of 64 patients with diabetic ketoacidosis complicated with acute pancreatitis admitted to our hospital from January 2018 to February 2019 were enrolled in this prospective study. They were divided into the study group and the control group according to the random number table method, with 32 patients in each group. Patients in the study group were given nutritional support combined with insulin therapy, and patients in the control group were given insulin therapy.There were no significant differences in general data including age, gender, body mass index, course and type of diabetes, acute physiology and chronic health evaluation II, RANSON, CT grades between the 2 groups before treatment (all P > .05). After 7 days of treatment, the clinical efficacy of the study group was significantly higher than that of the control group (study group vs control group, 94.44% vs 75.00%, P < .05). After 7 days of treatment, the levels of prealbumin and albumin in the study group were significantly higher than those in the control group (P < .05). After 7 days of treatment, the levels of PCT, CRP, TNF-α, PTX-3, and AMS in the 2 groups were significantly lower than those before treatment (P < .05), and the levels of PCT, CRP, TNF-α, PTX-3, and AMS in the study group were significantly lower than those in the control group. After 7 days of treatment, the levels of IgG, IgM, and IgA in the 2 groups were significantly higher than those before treatment, and the levels of IgG, IgM, and IgA in the study group were significantly higher than those in the control group (P < .05).Nutritional support combined with insulin is obviously effective in the treatment of diabetic ketoacidosis complicated with acute pancreatitis, which can improve serum protein levels, reduce inflammatory response, improve immune function, and is worthy of clinical application.

Abstract
BACKGROUND Data on analgesic effects of breast/formula milk sucking while receiving routine childhood immunizations are available only in early infancy, have rarely been compared in the same study, and are not accompanied by information on mothers' satisfaction/acceptance. Here we aimed to compare the analgesic effect of both methods vs. held-only controls up to 1 year of age, and verify mothers' satisfaction. METHODS Two to 12 months children subjected to vaccine were allocated into three groups: breastfed, formula-fed, and held-only controls. A video recording was performed to analyze pain parameters: crying latency/duration and specific scales [FLACC (Face, Legs, Activity, Cry, and Consolability), NIPS (Neonatal Infant Pain Scale)]. After the procedure, mothers filled in a satisfaction questionnaire. RESULTS One-hundred and sixty-two children were recruited: 54 breastfed, 35 formula fed, and 73 controls. Breastfed showed the longest crying latency, and together with formula fed, had the shortest duration and lowest pain scores. Most mothers appreciated not only the respective feeding-mediated pain mitigation method used, but also the simply-holding procedure. In all cases, they felt reassured, with an unexpected frequent underestimation of their child's pain during the shot. CONCLUSIONS The analgesic effect of breastfeeding during vaccination extends also to children >6 months old, and is obtained by formula too. Embracing the child may help to reassure mothers. IMPACT We confirmed the analgesic effect of breastfeeding during the vaccination procedures in early infancy. We show for the first time that this effect is extended also to children up to 1 year of age, and it may be obtained by formula feeding as well. Most mothers appreciated pain mitigation not only through feeding, but also the simply-holding procedure. In all cases, mothers felt reassured, with an unexpected frequent underestimation of their child' pain during the shot. The promotion of these easily feasible and well-accepted strategies should be further encouraged within health professionals during vaccination procedures.

Abstract
BACKGROUND Gastrointestinal dysfunction is a frequent and disabling manifestation of autoimmune polyendocrine syndrome type 1 (APS-1), a rare monogenic multiorgan autoimmune disease caused by the loss of central AIRE-controlled immune tolerance. OBJECTIVES This study aimed to understand the role of the gut microbiome in APS-1 symptoms and potentially alleviate common gastrointestinal symptoms by probiotic intervention. METHODS This study characterized the fecal microbiomes of 28 patients with APS-1 and searched for associations with gastrointestinal symptoms, circulating anti-cytokine autoantibodies, and tryptophan-related metabolites. Additionally, daily doses of the probiotic Lactobacillus rhamnosus GG were administered for 3 months. RESULTS Of 581 metagenomic operational taxonomic units (mOTUs) characterized in total, 14 were significantly associated with patients with APS-1 compared with healthy controls, with 6 mOTUs depleted and 8 enriched in patients with APS-1. Four overabundant mOTUs were significantly associated with severity of constipation. Phylogenetically conserved microbial associations with autoantibodies against cytokines were observed. After the 3-month intervention with the probiotic L rhamnosus GG, a subset of gastrointestinal symptoms were alleviated. L rhamnosus GG abundance was increased postintervention and corresponded with decreased abundances of Alistipes onderdonkii and Collinsella aerofaciens, 2 species positively associated with severity of diarrhea in patients with APS-1. CONCLUSIONS The APS-1 microbiome correlates with several APS-1 symptoms, some of which are alleviated after a 3-month L rhamnosus GG intervention. Autoantibodies against cytokines appear to shape the gut microbiome by positively correlating with a taxonomically consistent group of bacteria.
