Plain language summary
Inadequate sleep has been associated with an increased risk of cardiovascular disease and has an adverse impact on quality of life (QOL), metabolism and the immune system. Furthermore, sleep is associated with the body’s thermoregulation ability, which is closely associated with distal and proximal skin temperature, as well as core body temperature. The hypothesis of this study was that the physiological and psychological changes caused by insufficient sleep will differ according to cold hypersensitivity (CH). This study was an uncontrolled, before-and-after study with 3 days of 4-hour sleep restriction (SR) as intervention. A total of 130 participants completed the study. Results showed that less-than-optimal sleep duration leads to worsened stress and QOL and reduced low-density lipoprotein cholesterol levels. These changes were significant in the CH group compared to the non-CH group. Authors conclude that their findings provide additional information for evaluating the clinical risks posed by sleep disturbances and assessing the usual sleep patterns according to CH.
Abstract
Sleep disturbances are associated with cold hypersensitivity (CH) and characterized by excessive cold sensation in specific body parts and cold thermal discomfort. This study investigated the effects of short-term sleep restriction followed by a recovery phase on subjective health status, inflammation, and lipid metabolism in different types of CH. A total of 118 healthy adults aged 35 to 44 years without sleep disturbances were enrolled. Participants underwent 4-hour sleep restrictions per day for 3 days at a hospital and then returned to their daily lives for 4 days of rest. CH was assessed using a structured questionnaire with eight characteristic symptoms. A questionnaire and blood tests were administered baseline, after sleep restriction, and follow-up to assess cortisol, lipid profiles, and self-reported stress and quality of life (QOL). Participants were divided into CH (44.1%) and non-CH (55.9%) groups. The CH group showed increased stress, impaired QOL, and decreased low-density lipoprotein-cholesterol (LDL-C) levels compared to the non-CH group after sleep restriction. The variance for QOL (effect size = 0.07), subjective stress (effect size = 0.053), and LDL-C (effect size = 0.029) among time points depended on the group. Short-term sleep restriction was associated with deterioration of subjective health and reduced lipid metabolism; such changes were more evident in the CH group. Our findings suggest the need to consider an individual's CH status to assess the clinical risk associated with insufficient sleep.

Plain language summary
Depression and obesity are significant global health concerns. Depression can significantly impact physical health and reduced immune function. The aim of this study was to examine the potential benefits of a novel group psychological intervention program. The study is a preliminary quasi-experimental (single-arm) before-after pilot trial of a newly developed group-based psychological intervention program for people with depression and comorbid obesity. The program consisted of 10 two-hour group sessions held weekly. A total of 24 participants were recruited to the program across two pilot groups. Results indicate that there was a significant reduction in participants’ depression and anxiety scores by program-end. Some evidence also shows improvements in weight-related negative cognitions. Authors conclude that the group therapy program therefore has considerable potential to be effective in helping people enjoy better mental health and improve health outcomes.
Abstract
BACKGROUND Depression and obesity are significant global health concerns that commonly occur together. An integrated group cognitive behavioural therapy program was therefore developed to simultaneously address comorbid depression and obesity. METHODS Twenty-four participants (63% women, mean age 46 years) who screened positively for depression with a body mass index ≥25 were recruited from a self-referred general population sample. The group therapy program (10 two-hour weekly sessions) was examined in a single-arm, before-after pilot trial, conducted in a behavioural health clinic in Adelaide, Australia. Primary outcomes included survey and assessment-based analyses of depression, anxiety, body image, self-esteem, and weight (kg), assessed at four time-points: baseline, post-intervention, three-months and 12-months post program. Eighteen participants (75%) completed the program and all assessments. RESULTS Significant improvements in depression, anxiety, self-esteem and body shape concern scores, several quality of life domains, eating behaviours and total physical activity (among others) - but not weight - were observed over the course of the trial. CONCLUSIONS Results from this pilot trial suggest that combining interventions for depression and obesity may be useful. Further development of the program, particularly regarding the potential for physical health benefits, and a randomised controlled trial, are warranted. TRIAL REGISTRATION Trial registration: ANZCTR, ACTRN12617001079336, 13 July 2017. Retrospectively registered after date of the first consent (6 July 2017), but before the date of the first intervention session (20 July 2017).

Plain language summary
The causes of irritable bowel syndrome (IBS) are complex and not fully understood, yet the occurrence of migraine has been linked with this disease. As they have an association, therapies used for either disorder may have a direct impact on both. Food sensitivities have been shown to affect both migraines and IBS and the elimination of foods may be of benefit to both disorders. This randomised cross-over trial of 60 individuals with migraine and IBS assessed immune reactions to certain foods and aimed to determine the effect of eliminating these foods and the addition of probiotics on individuals with IBS and migraine. The results showed that after 14 weeks of treatment, only elimination diet combined with probiotics improved migraine and IBS symptoms, resulting in a decrease in the use of medications. Individuals treated with elimination diet or probiotics only did show an improvement in comparison to the start of the trial, however not when compared to the combination treatment It was concluded that elimination diet in combination with probiotics may be of benefit to relieve symptoms of migraine and IBS. This study could be used by healthcare professionals to understand possible causes of IBS and migraines, and that treatments may involve targeting both illnesses.
Abstract
Several research studies have revealed that migraine has a solid link with gastrointestinal diseases especially irritable bowel syndrome (IBS). This study was carried out to investigate therapeutic potential of diet based on IgG elimination combined with probiotics on migraine plus irritable bowel syndrome. A total of 60 patients diagnosed with migraine plus IBS were recruited for the study. IgG antibodies against 266 food varieties were detected by ELISA. Then, the subjects were randomized into three groups for treatment of IgG elimination diet or probiotics or diet combined with probiotics. Migraine symptom, gut function score, medication use, and serum serotonin level were measured at baseline, 7 weeks, and 14 weeks. Improvement of migraine and gut symptom was achieved at a certain time point. Reduced use of over-the-counter- (OTC-) analgesics was seen in all groups. However, use of triptans did not show significant difference. An increased serum serotonin level was seen in subjects treated with elimination diet and elimination diet combined with probiotics. IgG elimination diet combined with probiotics may be beneficial to migraine plus IBS. It may provide new insight by understanding the intricate relationship between migraine and gastrointestinal diseases.
