Oral vitamin D supplementation for adults with obesity undergoing bariatric surgery.

BACKGROUND: Vitamin D deficiency following bariatric surgery is common and is expected to be associated with a deleterious impact on the skeleton. However, the benefits of vitamin D supplementation and the optimal dose in this population is currently unknown. The available guidelines on the topic are derived from experts' opinions, and are not evidence based. OBJECTIVES: To compare the effects of different doses of vitamin D supplementation (low dose (less than 600 international units (IU)/day), moderate dose (600 IU/day to 3500 IU/day), high dose (greater than 3500 IU/day)) to each other or to placebo in adults living with obesity undergoing bariatric surgery. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, LILACS, two trial registries, and the reference lists of systematic reviews, articles, and health technology assessment reports without language restrictions. The last search of all databases was 27 June 2023, except Embase, which we searched on 14 August 2015. SELECTION CRITERIA: We included randomised controlled trials or controlled clinical trials on vitamin D supplementation comparing different doses or comparing vitamin D to placebo in people undergoing bariatric surgery. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Primary outcomes were fractures and adverse events. Secondary outcomes were vitamin D status, all-cause mortality, bone mineral change, secondary hyperparathyroidism, health-related quality of life, and muscle strength. We used GRADE to assess the certainty of the evidence for each outcome in each comparison. MAIN RESULTS: We identified five trials with 314 participants. We included three trials in the quantitative analysis. Moderate-dose vitamin D compared to placebo One trial compared moderate-dose vitamin D (3200 IU/day) to placebo. Moderate-dose vitamin D, compared to placebo, may improve vitamin D status and may result in little to no difference in the achieved parathyroid hormone level (achieved 25-hydroxyvitamin D level: mean difference (MD) 13.60 ng/mL, 95% confidence interval (CI) 7.94 to 19.26; achieved parathyroid hormone level: -6.60 pg/mL, 95% CI -17.12 to 3.92; 1 study, 79 participants; low-certainty evidence). The trial reported no adverse events in the moderate-dose vitamin D arm, but did not provide any information on adverse events in the placebo arm. There were no data on fractures, all-cause mortality, bone density change, health-related quality of life, and muscle strength. High-dose vitamin D compared to moderate-dose vitamin D Two trials in Roux-en-Y gastric bypass compared moderate-dose (equivalent dose 800 IU/day to 2000 IU/day) to high-dose (equivalent dose 5000 IU/day to 7943 IU/day) vitamin D. The evidence of high-dose vitamin D on adverse events is very uncertain (risk ratio (RR) 5.18, 95% CI 0.23 to 116.56; 2 studies, 81 participants; very low-certainty evidence). High-dose vitamin D may increase 25-hydroxyvitamin D levels compared to a moderate dose at 12 months, but the evidence is very uncertain (MD 15.55 ng/mL, 95% CI 3.50 to 27.61; I2 = 62%; 2 studies, 73 participants; very low-certainty evidence). High-dose vitamin D may have little to no effect on parathyroid hormone levels compared to a moderate dose at 12 months, but the evidence is very uncertain (MD 2.15 pg/mL, 95% CI -21.31 to 17.01; I2 = 0%; 2 studies, 72 participants; very low-certainty evidence). High-dose vitamin D may have little to no effect on mortality and bone mineral density at the lumbar spine, hip, and forearm, but the evidence is very uncertain. There were no data on fractures, health-related quality of life, or muscle strength. AUTHORS' CONCLUSIONS: No trials reported on fractures and the evidence available on adverse events is scarce. Moderate-dose vitamin D may improve vitamin D status and may result in little to no improvement in parathyroid hormone levels compared with placebo. High-dose vitamin D supplementation (greater than 3500 IU/day) may increase 25-hydroxyvitamin D levels, and may have little to no effect on parathyroid hormone levels, compared to a moderate dose, but the evidence for both is very uncertain. The currently available limited evidence may not have a significant impact on practice. Further studies are needed to explore the impact of vitamin D supplementation on fractures, adverse events, and musculoskeletal parameters in people undergoing bariatric surgery.

Comparison of Causes of Mortality Between Hospitalized Unsheltered Homeless Patients and Non-Homeless Sex and Age-Matched Controls: A Retrospective Case-Control Study.

Objectives: Roofless individuals represent the most severe category of homelessness. Their clinical characteristics and mortality patterns in Central and Eastern Europe are little known. Methods: A single-center retrospective case-control study at the internal medicine department in Bratislava, Slovakia was conducted. 5694 mortality records from 2010 to 2023 were screened, and 141 (118 men, 23 women) roofless individuals were identified. Patients were sex- and age-matched, with 141 patients from the cohort of non-homeless deceased patients. Results: Compared to controls, roofless people had a higher incidence of immobility (p = 0.02) and hypothermia (p < 0.0001) at admission. 83% of the roofless people were men, and 59% of the roofless people died before reaching old age (60+). Homeless men died more often from infectious disease (p = 0.02), pneumonia being the most common one (60%). Men from the control group died more often from liver diseases (p = 0.03). There were no significant differences in the causes of mortality between women. Conclusion: These findings could help to reduce the invisibility of the issue of massive premature mortality amongst homeless populations and roofless individuals, in particular.

A 7-Month Review of Clinical and Demographic Predictors of Childhood Mortality in a Tertiary Children Hospital in Freetown, Sierra Leone.

BACKGROUND: Sierra Leone ranks among nations with unacceptably high infant and under-5 mortality rates. Understanding the clinical and demographic dynamics that underpin paediatric mortalities is not only essential but fundamental to the formulation and implementation of effective healthcare interventions that would enhance child survival. SUBJECTS AND MATERIAL: This was a 7-month review of all mortalities from May 24th 2021 to December 31st 2021 at Ola During Children's Hospital in Freetown, Sierra Leone. Information on biodata, presenting complaints, illness duration, diagnoses, treatment given inclusive of point-of-care investigations, and duration of hospital stay retrieved from all mortalities were entered into Excel spreadsheets and were analyzed using SPSS version 25.0 for IBM. Multivariable regression analysis was done to determine factors independently associated with mortalities within 24 hours of admission. All associations were considered significant if p < 0.05. RESULTS: There were 840 deaths out of 5920 children admitted during the period giving a mortality of 14.2% with a male-to-female ratio of 1:1. Three hundred and four (36.2%) of these deaths occurred in the neonatal age group while 63.8% occurred in the post neonatal age group. Perinatal asphyxia was the leading cause of neonatal deaths while acute respiratory infections and severe malaria were the leading causes of post neonatal deaths. The majority (64.8%) of the mortalities occurred within the first 24 hours of admission. In a multivariable regression, only transfusion status and use of respiratory support were independently associated with mortality within 24 hours of admission (P<0.05). CONCLUSION: Paediatric mortality in Sierra Leone is high and is caused mainly by preventable morbidities such as perinatal asphyxia and infections. Most of the deaths occurred within 24 hours of admission. It is recommended that patients should be brought to the hospital early and preventive measures be instituted to address these causes.

CONTEXTE: La Sierra Leone se classe parmi les nations ayant des taux de mortalité infantile et des moins de cinq ans inacceptables. Comprendre la dynamique clinique et démographique qui sous-tend les mortalités pédiatriques est non seulement essentiel mais fondamental pour la formulation et la mise en œuvre d'interventions efficaces en matière de santé qui amélioreraient la survie des enfants. SUJETS ET MATÉRIEL: Il s'agissait d'une revue de sept mois de toutes les mortalités du 24 mai 2021 au 31 décembre 2021 à l'Hôpital Ola During Children's à Freetown, Sierra Leone. Les informations sur les données biométriques, les plaintes de présentation, la durée de la maladie, les diagnostics, les traitements administrés, y compris les investigations sur le lieu de soins, et la durée du séjour à l'hôpital ont été saisies dans des feuilles de calcul Excel et analysées à l'aide de SPSS version 25.0 pour IBM. Une analyse de régression multivariée a été effectuée pour déterminer les facteurs indépendamment associés aux mortalités dans les 24 heures suivant l'admission. Toutes les associations étaient considérées comme significatives si p < 0,05. RÉSULTATS: Il y a eu 840 décès sur 5920 enfants admis pendant la période, ce qui donne une mortalité de 14,2 % avec un rapport hommefemme de 1:1. Trois cent quatre (36,2 %) de ces décès sont survenus dans le groupe d'âge néonatal, tandis que 63,8 % sont survenus dans le groupe d'âge post-néonatal. L'asphyxie périnatale était la principale cause de décès néonatal, tandis que les infections respiratoires aiguës et le paludisme grave étaient les principales causes de décès post-néonatal. La majorité (64,8 %) des mortalités sont survenues dans les premières 24 heures suivant l'admission. Dans une régression multivariée, seul le statut transfusionnel et l'utilisation d'un support respiratoire étaient indépendamment associés à la mortalité dans les 24 heures suivant l'admission (P<0,05). CONCLUSION: La mortalité pédiatrique en Sierra Leone est élevée et est principalement causée par des morbidités évitables telles que l'asphyxie périnatale et les infections. La plupart des décès surviennent dans les 24 heures suivant l'admission. Il est recommandé que les patients soient amenés à l'hôpital tôt et que des mesures préventives soient mises en place pour traiter ces causes. MOTS CLÉS: Mortalité pédiatrique, Profil clinique, Déterminants, Freetown.

Influence of Subclinical Atherosclerosis Burden and Progression on Mortality.

BACKGROUND: Atherosclerosis is a dynamic process. There is little evidence regarding whether quantification of atherosclerosis extent and progression, particularly in the carotid artery, in asymptomatic individuals predicts all-cause mortality. OBJECTIVES: This study sought to evaluate the independent predictive value (beyond cardiovascular risk factors) of subclinical atherosclerosis burden and progression and all-cause mortality. METHODS: A population of 5,716 asymptomatic U.S. adults (mean age 68.9 years, 56.7% female) enrolled between 2008 and 2009 in the BioImage (A Clinical Study of Burden of Atherosclerotic Disease in an At Risk Population) study underwent examination by vascular ultrasound to quantify carotid plaque burden (cPB) (the sum of right and left carotid plaque areas) and by computed tomography for coronary artery calcium (CAC). Follow-up carotid vascular ultrasound was performed on 732 participants a median of 8.9 years after the baseline exam. All participants were followed up for all-cause mortality, the primary outcome. Trend HRs are the per-tertile increase in each variable. RESULTS: Over a median 12.4 years' follow-up, 901 (16%) participants died. After adjustment for cardiovascular risk factors and background medication, baseline cPB and CAC score were both significantly associated with all-cause mortality (fully adjusted trend HR: 1.23; 95% CI: 1.16-1.32; and HR: 1.15; 95% CI: 1.08-1.23), respectively (both P < 0.001), thus providing additional prognostic value. cPB performed better than CAC score. In participants with a second vascular ultrasound evaluation, median cPB progressed from 29.2 to 91.3 mm3. cPB progression was significantly associated with all-cause mortality after adjusting for cardiovascular risk factors and baseline cPB (HR: 1.03; 95% CI: 1.01-1.04 per absolute 10-mm3 change; P = 0.01). CONCLUSIONS: Subclinical atherosclerosis burden (cPB and CAC) in asymptomatic individuals was independently associated with all-cause mortality. Moreover, atherosclerosis progression was independently associated with all-cause mortality.

Outline and Medico-legal Drift of Asphyxial Deaths.

Cases of asphyxial death are frequently come across and the numbers are remarkable now-a-days. The study was aimed to estimate the frequency and to determine the socio-demographic pattern of the victims of asphyxial death. It was a cross-sectional variety of descriptive study and carried out in the Department of Forensic Medicine, Dhaka Medical College, Bangladesh from 1st January 2018 to 31st December 2019. A predesigned proforma was made first, and then various data were assembled, tabulated and analyzed there. In the midst of 2199 medicolegal autopsies, there were 224 cases of asphyxial death. Male victims (62.05%) were mostly found and the most affected age group was 30-39 years (35.26%). Victims were predominantly married (53.57%) and were mainly from urban areas (38.39%). The Muslims (76.78%) were the major victims followed by the Hindus (17.41%), Christians (2.67%) and the Buddhists (1.78%). Maximum victims were unemployed (31.69%) followed by students, day laborers & cultivators. Hangings (54.01%) were mostly encountered followed by drowning (23.21%) and throttling (7.14%). Majority of the cases were suicidal (58.48%) followed by homicidal (24.55%) and accidental (16.96%). The main provoking factors in suicidal cases were unemployment (22.13%) followed by failure in examination (20.61%) and domestic violence (12.97%). Hangings were proven to be suicidal. In cases of drowning manner of death could not be given and throttling were homicidal by autopsy.

Evaluating the accuracy of International Classification of Disease Perinatal Mortality (ICD-PM) codes assigned on death certificates before and after expert panel review: a mixed methods observational study.

INTRODUCTION: The present study was conducted with the aim of evaluating the accuracy of International Classification of Disease Perinatal Mortality (ICD-PM) codes assigned on death certificates before and after an expert panel review. METHOD: The present study was a mixed methods observational study conducted at Umm al-Benin Hospital, the sole specialized obstetrics and gynecology center affiliated with Mashhad University of Medical Sciences. The study comprised three distinct stages: (1) Collecting primary ICD-PM codes assigned to perinatal death certificates, along with other relevant information, from October 2021 to March 2022; (2) Examining the circumstances of each perinatal death case and re-identifying the causes of death through a consensus process involving a panel of experts comprising pediatricians, obstetrics and gynecology specialists, and nursing and midwifery experts; presenting the new ICD-PM code; (3) Comparing the ICD-PM codes assigned to perinatal death certificates before and after the expert panel's evaluation. RESULT: During the study period, a total of seven specialized panels were conducted to examine perinatal deaths. Out of the 71 cases, 41 were carefully reviewed by experts. These cases included 32 stillbirths and nine neonatal deaths. The examination process followed specific inclusion and exclusion criteria. The findings revealed that there were no significant changes in the causes of neonatal deaths. However, it was notable that 80% of the previously unknown causes of stillbirths were successfully identified. Notably, the occurrence of stillbirths increased by 78% due to maternal causes and conditions. CONCLUSION: Convening panels of experts to discuss the causes of perinatal deaths can effectively reduce the percentage of unknown causes, as classified by ICD-PM. This approach also guarantees the availability of essential data for implementing effective interventions to decrease preventable perinatal deaths.

Coronary artery bypass grafting in octogenarians: a nomogram for predicting all-cause mortality.

BACKGROUND: The benefits and risks of coronary artery bypass grafting (CABG) in octogenarians remain unclear. This study aimed to identify the predictors of increased risk of all-cause mortality in octogenarian patients after CABG. METHODS: We retrospectively analyzed the data of 1636 octogenarians who underwent isolated elective on-pump CABG between 2007 and 2016. The primary endpoint was mortality from any cause. The Kaplan-Meier curve was generated for mortality. A univariate Cox regression was performed for preprocedural and procedural variables. The Akaike information criterion (AIC) using the Cox proportional hazard model was applied to determine the strongest predictors. We designed a nomogram based on the selected variables to calculate the mortality risk after one, five, and ten years. The bootstrap resampling based on the C-index was performed to validate the final model. Calibration plots were created at different time points. RESULTS: The mean age of the patients was 82.03 years (SD = 1.74), and 74% were male. In a median follow-up of 9.2 (95% CI 9.0,9.5) years, 626 (38.2%) patients died. After the selection of best predictors based on AIC, the multivariable Cox regression showed that ejection fraction < 40 (HR 1.41, 95% CI 1.21-1.65, P < 0.001), two-vessel disease (HR: 0.59, 95% CI 0.40-0.89, P = 0.012), peripheral vascular disease (HR 1.52, 95% CI 1.05-2.21, P = 0.027), and valvular heart disease (HR 1.45, 95% CI 1.24-1.69, P < 0.001) were the significant predictors of all-cause mortality. CONCLUSION: Octogenarians who undergo CABG have a high mortality risk, influenced by several preprocedural and procedural risk factors. The proposed nomogram can be considered for optimizing the management of this vulnerable age group. Clinical registration number IR.TUMS.THC.REC.1400.081.

Inhaled Corticosteroids Particle Size and Risk of Hospitalization Due to Exacerbations and All-Cause Mortality in Patients with Chronic Obstructive Pulmonary Disease. A Nationwide Cohort Study.

Background: Extra-fine particle inhaled corticosteroids (ICS) improve peripheral airway distribution, but their effect on risk of exacerbations and all-cause mortality in patients with chronic obstructive pulmonary disease (COPD) is unclear. Methods: This observational cohort study compares patients with COPD who received extra-fine particle ICS to those who received standard particle size ICS from 2010 to 2017 while followed in outpatient clinics. The primary outcome was the time to a COPD exacerbation that required hospitalization, with all-cause mortality as a secondary outcome. Data were analyzed using an adjusted Cox proportional hazards model and a competing risk analysis. Two predefined subgroup analyses of patients treated with pressurised metered dose inhalers (pMDIs) and patients with a previous exacerbation history, was carried out. Lastly, we created a propensity score matched cohort as a sensitivity analysis. Results: Of the 40,489 patients included, 38,802 (95.8%) received stand particle size ICS and 1,687 (4.2%) received extra-fine particle ICS. In total 7,058 were hospitalized with a COPD exacerbation, and 4,346 died. No significant protective effect of extra-fine particle ICS against hospitalization due to COPD exacerbations (HR 0.93, 95% CI 0.82-1.05, p=0.23) or all-cause mortality (HR 1.00, 95% CI 0.85-1.17, p=0.99) was found when compared to standard particle size ICS. However, in the subgroup analysis of patients treated with pMDIs, extra-fine particle ICS was associated with reduction in risk of exacerbations (HR 0.72, 95% CI 0.63-0.82, p<0.001) and all-cause mortality (HR 0.72, 95% CI 0.61-0.86, p<0.001). Conclusion: The administration of extra-fine particle ICS was not associated with reduced risk of exacerbations or all-cause mortality in our primary analysis. A subgroup consisting of patients treated with pMDIs suggested potential protective benefits.

Cholecystectomy and risk of cardiovascular disease, all-cause and cause-specific mortality: a systematic review and updated meta-analysis.

Objective: Questions remain about the association among cholecystectomy, cardiovascular disease, all-cause and cause-specific mortality. We performed a systematic review and meta-analysis to clarify these associations. Methods: PubMed, Web of Science, Embase, and Cochrane Library databases were searched up to February 2024. Summary relative risks (RRs) and 95% confidence intervals (CIs) were calculated using a DerSimonian-Laird random effects model. Results: We screened 16,595 articles and included 14 studies. No significant association was found between cholecystectomy and cardiovascular disease (CVD), with RR being 1.03 (95% CI [0.77-1.37], p = 0.848, I 2 = 99.6%), even in results with high heterogenous studies excluded (RR 1.20, 95% CI [0.97-1.49], p = 0.095, I 2 = 77.7%). Same result was proved in its subtype, coronary heart disease (RR 1.06, 95% CI [0.84-1.33], p = 0.633, I2 = 96.6%). Cholecystectomy increased CVD risk compared with healthy controls without gallstones (RR 1.19, 95% CI [1.05-1.35], p = 0.007, I 2 = 83.3%) and lowered CVD risk compared with gallstone carriers (RR 0.62, 95% CI [0.57-0.67], p < 0.001, I 2 = 82.1%). As for mortality, increase in the risk for all-cause (RR 1.17, 95% CI [1.03-1.34], p = 0.020, I 2 = 51.6%) and cardiovascular (RR 1.24, 95% CI [1.06-1.47], p = 0.009, I 2 = 20.7%) mortality, but not for cancer mortality (RR 1.18, 95% CI [0.95-1.47], p = 0.131, I 2 = 0.0%), were observed after cholecystectomy. Conclusion: Cholecystectomy may not be associated with the overall development of CVD, as well as CHD. Cholecystectomized patients showed increased CVD risk compared with healthy controls without gallstones, but decreased CVD risk compared with gallstone patients. Increased risk for all-cause and cardiovascular, but not cancer mortality was observed following cholecystectomy.
