A systematic review of the burden of, access to services for and perceptions of patients with overweight and obesity, in humanitarian crisis settings.

INTRODUCTION: Excess body weight causes 4 million deaths annually across the world. The number of people affected by humanitarian crises stands at a record high level with 1 in 95 people being forcibly displaced. These epidemics overlap. Addressing obesity is a post-acute phase activity in non-communicable disease management in humanitarian settings. Information is needed to inform guidelines and timing of interventions. The objective of this review was to explore the prevalence of overweight and obesity in populations directly affected by humanitarian crises; the cascade of care in these populations and perceptions of patients with overweight and obesity. METHODS: Literature searches were carried out in five databases. Grey literature was identified. The population of interest was non-pregnant, civilian adults who had experience of humanitarian crises (armed conflict, complex emergencies and natural disasters). All study types published from January 1st, 2011, were included. Screening, data extraction and quality appraisal were carried out in duplicate. A narrative synthesis is presented. RESULTS: Fifty-six reports from forty-five studies were included. Prevalence estimates varied widely across the studies and by subgroups. Estimates of overweight and obesity combined ranged from 6.4% to 82.8%. Studies were heterogenous. Global distribution was skewed. Increasing adiposity was seen over time, in older adults and in women. Only six studies were at low risk of bias. Body mass index was the predominant measure used. There were no studies reporting cascade of care. No qualitative studies were identified. CONCLUSION: Overweight and obesity varied in crisis affected populations but were rarely absent. Improved reporting of existing data could provide more accurate estimates. Worsening obesity may be prevented by acting earlier in long-term crises and targeting risk groups. The use of waist circumference would provide useful additional information. Gaps remain in understanding the existing cascade of care. Cultural norms around diet and ideal body size vary.

Associations between socioeconomic deprivation and pharmaceutical prescribing in primary care in England.

BACKGROUND: Socioeconomic deprivation is associated with health inequality. Previous studies have described associations between primary care prescribing rates and deprivation for individual drugs or drug classes. We explore the correlation between socioeconomic deprivation and the rate of prescribing of individual pharmaceutical drugs, and drug classes, in primary care in England, to identify prescribing inequalities that would require further investigation. METHODS: In this cross-sectional study, national primary care prescribing data, by primary care practice, were retrieved for the calendar year 2019 in England. Socioeconomic deprivation was quantified using the Index of Multiple Deprivation (IMD) score. Correlations were calculated using Spearman's rank correlation coefficient (ρ), adjusting for practice list size and demographics, with a Bonferroni-corrected p value threshold of 5×10-5. RESULTS: We included 1.05 billion prescription items dispensed from 6896 England practices. 142/206 (69%) drug classes and 505/774 (65%) drugs were significantly correlated with IMD score (p<5×10-5). Of the 774 included drugs, 31 (4%) were moderately positively associated with IMD score (ρ>0.4). Only one was moderately negatively correlated with IMD score (ρ<-0.4), suggesting higher prescribing rates in more affluent areas. The drug classes most strongly associated with IMD score included opioid and non-opioid analgesics, antipsychotics and reflux medications. Drug classes most strongly associated with affluence included epinephrine, combined oral contraceptives and hormone replacement therapy. CONCLUSION: We identify novel associations of prescribing with deprivation. Further work is required to identify the underlying reasons for these associations so that appropriate interventions can be formulated to address drivers of inequality.

Outpatient Extraperitoneal Single-Port Robotic Radical Prostatectomy.

OBJECTIVE: To assess the safety and feasibility of extraperitoneal single-port robotic assisted laparoscopic radical prostatectomy using the da Vinci SP robotic platform for same-day surgery. METHODS: Extraperitoneal single-port robotic prostatectomy (ESRP) using the da Vinci SP platform was performed on 60 patients with clinically localized prostate cancer and no prior definitive therapy. An enhanced recovery protocol was used in the perioperative period and minimal to no opiates were used in these patients. Preoperative, perioperative, and postoperative data were collected in a prospectively maintained institutional review board approved database and evaluated in a retrospective fashion. RESULTS: Mean operative time was 198 minutes and mean estimated blood loss was 179 mL. No patients required blood transfusion and there were no intraoperative complications. Pain at discharge was 0-1 in 37% of patients. Forty-five patients (75%) were discharged home the day of surgery, including patients with all surgical start times. When excluding patients that were planned for an overnight stay preoperatively or patients whose surgery finished after 6 PM, 88% of patients were discharged home the day of surgery and 96% were discharged within 24 hours of surgery. Median length of stay was 4.2 hours. Fourty-eight percent of patients required 0-1 pads at 30 days postoperatively in patients with 30 day follow data (n = 58) and 76% of patients reported requiring 0-1 pads per day by 90 days postoperatively (n = 37). CONCLUSION: ESRP using the da Vinci SP platform can be performed safely and reproducibly as a same-day outpatient surgery with minimal to no opiate use, excellent pain control, and acceptable short term functional and oncological outcomes.

CD4+FOXP3+ regulatory T cells confer long-term regulation of factor VIII-specific immune responses in plasmid-mediated gene therapy-treated hemophilia mice.

Gene transfer of a factor VIII (FVIII) plasmid into hemophilia A (HemA) mice achieved supraphysiologic FVIII expression, but triggered production of high-titer FVIII-specific antibodies and loss of functional FVIII activity. To test whether FVIII-specific regulatory T cells (Tregs) can modulate immune responses against FVIII, we developed a HemA mouse model in which all T cells overexpressed Foxp3 (HemA/Foxp3-Tg). FVIII plasmid therapy did not induce antibody production in HemA/Foxp3-Tg mice. CD4(+)Foxp3(+) T cells isolated from plasmid-treated HemA/Foxp3-Tg mice significantly suppressed proliferation of FVIII-stimulated CD4(+) effector T cells. The percentage of CD4(+) T cells expressing CD25, glucocorticoid-induced tumor necrosis factor receptor, and cytotoxic T lymphocyte antigen 4 increased significantly in spleen and peripheral blood for 9 weeks. Mice receiving adoptively transferred Tregs from FVIII-exposed HemA/Foxp3-Tg mice produced significantly reduced antibody titers compared with controls after initial challenge with FVIII plasmid and second challenge 16 weeks after first plasmid treatment. Adoptively transferred Tregs engrafted and distributed at 2% to 4% in the Treg compartment of blood, lymph nodes, and spleens of the recipient mice and induced activation of endogenous Tregs; the engraftment decreased to negligible levels over 8 to 12 weeks. Antigen-specific Tregs can provide long-lasting protection against immune responses in vivo and limit recall responses induced by a second challenge via infectious tolerance.
