The impact of primary health care on AIDS incidence and mortality: A cohort study of 3.4 million Brazilians.

Primary Health Care (PHC) is essential for effective, efficient, and more equitable health systems for all people, including those living with HIV/AIDS. This study evaluated the impact of the exposure to one of the largest community-based PHC programs in the world, the Brazilian Family Health Strategy (FHS), on AIDS incidence and mortality. A retrospective cohort study carried out in Brazil from January 1, 2007 to December 31, 2015. We conducted an impact evaluation using a cohort of 3,435,068 ≥13 years low-income individuals who were members of the 100 Million Brazilians Cohort, linked to AIDS diagnoses and deaths registries. We evaluated the impact of FHS on AIDS incidence and mortality and compared outcomes between residents of municipalities with low or no FHS coverage (unexposed) with those in municipalities with 100% FHS coverage (exposed). We used multivariable Poisson regressions adjusted for all relevant municipal and individual-level demographic, socioeconomic, and contextual variables, and weighted with inverse probability of treatment weighting (IPTW). We also estimated the FHS impact by sex and age and performed a wide range of sensitivity and triangulation analyses; 100% FHS coverage was associated with lower AIDS incidence (rate ratio [RR]: 0.76, 95% CI: 0.68 to 0.84) and mortality (RR: 0.68, 95%CI: 0.56 to 0.82). FHS impact was similar between men and women, but was larger in people aged ≥35 years old both for incidence (RR: 0.62, 95% CI: 0.53 to 0.72) and mortality (RR: 0.56, 95% CI: 0.43 to 0.72). The absence of important confounding variables (e.g., sexual behavior) is a key limitation of this study. AIDS should be an avoidable outcome for most people living with HIV today and our study shows that FHS coverage could significantly reduce AIDS incidence and mortality among low-income populations in Brazil. Universal access to comprehensive healthcare through community-based PHC programs should be promoted to achieve the Sustainable Development Goals of ending AIDS by 2030.

Cardiopulmonary Bypass Blood Flow Rates and Major Adverse Kidney Events in Cardiac Surgery: A Propensity Score-adjusted Before–After Study

ObjectiveCardiac surgery associated-acute kidney injury (CSA-AKI) is a common and serious postoperative complication of cardiac surgery, which is associated with increased postoperative morbidity and mortality. This study aimed to explore the association between CPB blood flow rate (CPB-BFR) and major adverse kidney events at day 30 (MAKE30). DesignRetrospective single-center before-after observational study. Patients were divided in two groups according to CPB flow rates: a first group with an institutional protocol targeting a CPB-BFR >2.2 L/min/m² (low CPB-BFR group), and a second group with a modified institutional protocol targeting a CPB-BFR >2.4 L/min/m² (high CPB-BFR group). The primary outcome was MAKE 30, defined as the composite of death, renal replacement therapy or persistent renal dysfunction. SettingThe data were collected from clinical routines in university hospital. ParticipantsAdult patients who underwent elective and urgent cardiac surgery without severe chronic renal failure, for whom CPB duration was ≥90 minutes. Interventions533 patients were included (low CPB-BFR group n=270, high CPB-BFR group n=263). Measurements and Main ResultsA significant decrease in MAKE 30 was observed in the high CPB-BFR group (3% vs. 8%; OR 0.779, 95% CI [0.661;0.919]; P<0.001) mainly mediated by a lower 30-day mortality in the high CPB-BFR group (1% vs. 5%; OR 0.697, 95% CI [0.595;0.817]; P= 0.001), as was renal replacement therapy (1% vs. 4%; OR 0.739, 95% CI [0.604;0.904]; P=0.016). ConclusionsIn patients undergoing cardiac surgery, increased CPB-BFR was associated with a reduction in MAKE 30 including mortality and renal replacement therapy.

Efficacy of Interceptor G2, Royal Guard and PermaNet 3.0 against pyrethroid-resistant Anopheles gambiae s.l. from Za-Kpota, southern Benin: an experimental hut trial

BackgroundThe widespread use of insecticide-treated nets (ITNs) has significantly contributed to the reduction in malaria cases and deaths observed across Africa. Unfortunately, this control strategy is threatened by the rapid spread of pyrethroid resistance in malaria vectors. Dual-active-ingredient insecticidal nets are now available to mitigate the impact of pyrethroid resistance. To facilitate evidence-based decisions regarding product selection in specific use settings, data are needed on the efficacy of these different nets against local mosquito populations.MethodsTwo experimental hut trials were performed in Za-Kpota, southern Benin in 2021 to evaluate the performance of Interceptor G2 (BASF), Royal Guard (Disease Control Technologies) and PermaNet 3.0 (Vestergaard Frandsen), all dual-active-ingredient bednets, in comparison to untreated or standard pyrethroid-treated bednets, against free-flying wild Anopheles gambiae mosquitoes. The performance of some of these next-generation nets was compared to the same type of nets that have been in use for up to 2 years. Mosquitoes collected in the huts were followed up after exposure to assess the sublethal effects of treatments on certain life-history traits.ResultsThe predominant species in the study site was Anopheles gambiae sensu stricto (An. gambiae s.s.). Both Anopheles coluzzii and An. gambiae s.s. were resistant to pyrethroids (deltamethrin susceptibility was restored by piperonyl butoxide pre-exposure). In the experimental hut trials, the highest blood-feeding inhibition (5.56%) was recorded for the Royal Guard net, relative to the standard PermaNet 2.0 net (44.44% inhibition). The highest 72-h mortality rate (90.11%) was recorded for the Interceptor G2 net compared to the PermaNet 2.0 net (56.04%). After exposure, the risk of death of An. gambiae sensu lato (An. gambiae s.l.) was 6.5-fold higher with the Interceptor G2 net and 4.4-fold higher with the PermaNet 3.0 net compared to the respective untreated net. Lower mosquito mortality was recorded with an aged Interceptor G2 net compared to a new Interceptor G2 net. Oviposition rates were lower in mosquitoes collected from huts containing ITNs compared to those of untreated controls. None of the mosquitoes collected from huts equipped with Royal Guard nets laid any eggs.ConclusionsThe Royal Guard and Interceptor G2 nets showed a potential to significantly improve the control of malaria-transmitting vectors. However, the PermaNet 3.0 net remains effective in pyrethroid-resistant areas.Graphical

Understanding the Intergenerational Impact of Migration: An Adult Mortality Advantage for the Children of Forced Migrants?

Children of immigrants often have excess mortality rates, in contrast to the low mortality typically exhibited by their parents' generation. However, prior research has studied children of immigrants who were selected for migration, thereby rendering it difficult to isolate the intergenerational impact of migration on adult mortality. We use semiparametric survival analysis to carry out a total population cohort study estimating all-cause and cause-specific mortality among all adult men and women from age of 17 years among all men and women born in 1953-1972 and resident in Finland in 1970-2020. We compare children of forced migrants from ceded Karelia, an area of Finland that was ceded to Russia during the Second World War, with the children of parents born in present-day Finland. Children with two parents who were forced migrants have higher mortality than children with two parents born in Northern, Southern, and Western Finland, but similar or lower mortality than the subpopulation of children whose parents were born in the more comparable areas of Eastern Finland. For women and men, a mortality advantage is largest for external causes and persists after controlling for socioeconomic factors. Our findings suggest that forced migration can have a beneficial impact on the mortality of later generations, at least in the case where forced migrants are able to move to contextually similar locations that offer opportunities for rapid integration and social mobility. The findings also highlight the importance of making appropriate comparisons when evaluating the impact of forced migration.

L-shaped association between serum chloride levels with 90-day and 365-day all-cause mortality in critically ill patients with COPD: a retrospective cohort study

This study aimed to investigate the association between serum chloride levels and all-cause mortality in critically ill patients with chronic obstructive pulmonary disease (COPD). Data from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database were extracted for analysis. Demographic information, laboratory results, medical histories, vital signs, and prognosis-related data were collected. Cox proportional hazard models were used to assess the relationship between serum chloride levels and 90-day and 365-day mortality. Subgroup analyses were conducted to explore potential interactions between serum chloride levels and various factors. The study included patients with a median age of 72.00 years, of whom 52.39% were male. Higher quartiles of serum chloride levels were associated with significantly lower levels of weight, RBC, platelet, hemoglobin, and other variables (P < 0.05), accompanied by lower 90-day and 365-day mortality (P < 0.05). Cox proportional hazard model indicated that the risk of death was significantly lower in the fourth quartile of serum chloride levels compared with the first quartile after adjusting for confounders (90-day HR = 0.54, 365-day HR = 0.52, both P < 0.05). An L-shape relationship was observed, with risks of death decreasing as serum chloride levels increased, although the magnitude decreased when levels reached 102 mmol/L. This study demonstrated an independent L-shaped association between serum chloride levels and all-cause mortality in critically ill patients with COPD. This finding helps us to understand the prognostic value of serum chloride levels in critically ill patients with COPD.

“Multidisciplinary fast-track” care can significantly reduce risk of mortality among hip fracture patients at least 80 years old: a single-center retrospective study

Background“Multidisciplinary fast-track” (MFT) care can accelerate recovery and improve prognosis after surgery, but whether it is effective in older people after hip fracture surgery is unclear.MethodsWe retrospectively compared one-year all-cause mortality between hip fracture patients at least 80 years old at our institution who underwent hip fracture surgery between January 2014 and December 2018 and who then received MFT or conventional care. Multivariable regression was used to assess the association between MFT care and mortality after adjustment for confounders.ResultsThe final analysis included 247 patients who received MFT care and 438 who received conventional orthopedic care. The MFT group showed significantly lower one-year mortality (8.9% vs. 14.4%, P = 0.037). Log-rank testing of Kaplan-Meier survival curves confirmed the survival advantage. However, the two groups did not differ significantly in rates of mortality during hospitalization or at 30 or 90 days after surgery. Regression analysis confirmed that MFT care was associated with lower risk of one-year mortality (hazard ratio [HR] 0.47, 95% confidence interval [CI] 0.281–0.788, P = 0.04), and the survival benefit was confirmed in subgroups of patients with anemia (HR 0.453, 95% CI 0.268–0.767, P = 0.003) and patients with American Society of Anesthesiologists grade III (HR 0.202, 95% CI 0.08–0.51, P = 0.001).ConclusionsMFT care can reduce one-year mortality among hip fracture patients at least 80 years old. This finding should be verified and extended in multi-center randomized controlled trials.

The Current State of Coronary Revascularization: Coronary Artery Bypass Graft Surgery Versus Percutaneous Coronary Interventions.

The optimal revascularization strategy for coronary artery disease depends on various factors, such as disease complexity, patient characteristics, and preferences. Including a heart team in complex cases is crucial to ensure optimal outcomes. Decision-making between percutaneous coronary intervention and coronary artery bypass grafting must consider each patient's clinical profile and coronary anatomy. While current practice guidelines offer some insight into the optimal revascularization approach for the various phenotypes of coronary artery disease, the evidence to support either strategy continues to evolve and grow. Given the large amount of contemporary data on revascularization, this review aims to comprehensively summarize the literature on coronary artery bypass grafting and percutaneous coronary intervention in patients across the spectrum of coronary artery disease phenotypes. Contemporary evidence suggests that for patients with triple vessel disease, coronary artery bypass grafting is preferred over percutaneous coronary intervention due to better long-term outcomes, including lower rates of death, myocardial infarction, and target vessel revascularization. Similarly, for patients with left main coronary artery disease, both percutaneous coronary intervention and coronary artery bypass grafting can be considered, as they have shown similar efficacy in terms of major adverse cardiac events, but there may be a slightly higher risk of death with percutaneous coronary intervention. For proximal left anterior descending artery disease, both percutaneous coronary intervention and coronary artery bypass grafting are viable options, but coronary artery bypass grafting has shown lower rates of repeat revascularization and better relief from angina. The Synergy Between PCI with Taxus and Cardiac Surgery score can help in decision-making by predicting the risk of adverse events and guiding the choice between percutaneous coronary intervention and coronary artery bypass grafting. European and American guidelines both agree with including a heart team that can develop and lay out individualized, optimal treatment options with respect for patient preferences. The debate between coronary artery bypass grafting versus percutaneous coronary intervention in multiple different scenarios will continue to develop as technology and techniques improve for both procedures. Risk factors, pre, peri, and post-procedural complications involved in both revascularization strategies will continue to be mitigated to optimize outcomes for those patients for which coronary artery bypass grafting or percutaneous coronary intervention provide ultimate benefit. Methods to avoid unnecessary revascularization continue to develop as well as percutaneous technology that may allow patients to avoid surgical intervention when possible. With such changes, revascularization guidelines for specific patient populations may change in the coming years, which can serve as a limitation of this time-dated review.

Functional Outcome and Hemorrhage Rates After Bridging Therapy With Tenecteplase or Alteplase in Patients With Large Ischemic Core.

IV tenecteplase is an alternative to alteplase before mechanical thrombectomy (MT) in patients with large-vessel occlusion (LVO) ischemic stroke. Little data are available on its use in patients with large ischemic core. We aimed to compare the efficacy and safety of both thrombolytics in this population. We conducted a retrospective analysis of patients with anterior circulation LVO strokes and diffusion-weighed imaging Alberta Stroke Program Early CT Score (DWI-ASPECTS) ≤5 treated with tenecteplase or alteplase before MT from the TETRIS (tenecteplase) and ETIS (alteplase) French multicenter registries. Primary outcome was reduced disability at 3 months (ordinal analysis of the modified Rankin scale [mRS]). Safety outcomes were 3-month mortality, parenchymal hematoma (PH), and symptomatic intracranial hemorrhage (sICH). We used propensity score overlap weighting to reduce baseline differences between treatment groups. We analyzed 647 patients (tenecteplase: n = 194; alteplase: n = 453; inclusion period 2015-2022). Median (interquartile range) age was 71 (57-81) years, with NIH Stroke Scale score 19 (16-22), DWI-ASPECTS 4 (3-5), and last seen well-to-IV thrombolysis and puncture times 165 minutes (130-226) and 260 minutes (203-349), respectively. After MT, the successful reperfusion rate was 83.1%. After propensity score overlap weighting, all baseline variables were well balanced between both treatment groups. Compared with patients treated with alteplase, patients treated with tenecteplase had better 3-month mRS (common odds ratio [OR] for reduced disability: 1.37, 1.01-1.87, p = 0.046) and lower 3-month mortality (OR 0.52, 0.33-0.81, p < 0.01). There were no significant differences between thrombolytics for PH (OR 0.84, 0.55-1.30, p = 0.44) and sICH incidence (OR 0.70, 0.42-1.18, p = 0.18). Our data are encouraging regarding the efficacy and reassuring regarding the safety of tenecteplase compared with that of alteplase in bridging therapy for patients with LVO strokes and a large ischemic core in routine clinical care. These results support its consideration as an alternative to alteplase in bridging therapy for patients with large ischemic cores. NCT03776877 (ETIS registry) and NCT05534360 (TETRIS registry). This study provides Class III evidence that patients with anterior circulation LVO stroke and DWI-ASPECTS ≤5 treated with tenecteplase vs alteplase before MT experienced better functional outcomes and lower mortality at 3 months.

Polymer-free stents for percutaneous coronary intervention in diabetic patients: a systematic review and meta-analysis.

Aim: To compare the efficacy of polymer-free drug-eluting stents (PF-DES) versus other stents in diabetic patients with coronary artery diseaseundergoing percutaneous coronary interventions. Materials & methods: A systematic review and meta-analysis were performed to identify pertinent randomized controlled trials. The primary end point was the occurrence of target lesion failure. Results: Eight randomized controlled trials were included for a total of 4854subjects. The PF-DES group experienced a trend in favor of a lower rate of target lesion failure (Incidence rate ratio=0.91; p=0.11) and a significantly lower rate of cardiac mortality, as compared with the control group (Incidence rate ratio=0.82; p=0.04). However, statistical significance was lost if bare-metal stent patients were excluded and a trend in favor of the PF-DES strategy was reported only for cardiac mortality. Conclusion: PF-DES could be a valuable strategy in diabetic patients with coronary artery disease undergoing percutaneous coronary interventions.

The differential impacts of COVID-19 mortality on mental health by residential geographic regions: The Los Angeles Pandemic Surveillance Cohort Study.

This study examines the association between changes in mental health before and during the COVID-19 pandemic and COVID-19 mortality across geographic areas and by race/ethnicity. A cross-sectional survey was conducted in Los Angeles County between April and May 2021. The study used the Patient Health Questionnaire-2 to assess major depression risk. Participants' home ZIP codes were classified into low, middle, and high COVID-19 mortality impacted areas (CMIA). While there were existing mental health disparities due to differences in demographics and social determinants of health across CMIA in 2018, the pandemic exacerbated the disparities, especially for residents living in high CMIA. Non-White residents in high CMIA reported the largest deterioration in mental health. Differences in mental health by CMIA persisted after controlling for resident characteristics. Living in an area with higher COVID-19 mortality rates may have been associated with worse mental health, with Non-White residents reporting worse mental health outcomes in the high mortality area. It is crucial to advocate for greater mental health resources in high COVID-19 mortality areas especially for racial/ethnic minorities.

Ferric carboxymaltose for iron deficiency in patients with heart failure: a systematic review and meta-analysis.

Aim: Iron deficiency (ID) is associated with heart failure (HF) in a considerable proportion of patients. To improve the quality of life, lower the frequency of hospitalizations, and lower mortality rates of chronic HF patients (HF), this meta-analysis will look into the role of iron supplementation using ferric carboxymaltose (FCM). Methods & results: From inception until 1 October 2023, we conducted a thorough literature search of electronic databases for peer-reviewed publications. Around 5229 HF patients were included, of which 2691 received FCM while 2538 received placebo. Conclusion: FCM reduces HF-related hospitalizations but doesn't improve overall or cardiovascular mortality in those with HF and ID. The overall results support FCM's role in managing iron deficiency in heart failure.

The search for optimal nocturnal diurnal heart rate Index targets in ICU patients: a retrospective observational study from large ICU database.

Circadian rhythms play a crucial role in cardiovascular health, with the nocturnal diurnal heart rate index (NDHRI) reflecting significant circadian variations. However, the optimal NDHRI target in Intensive Care Unit (ICU) patients remains undefined. This study aims to establish an evidence-based NDHRI target range and assess its association with mortality. Data from the eICU Collaborative Research Database (n = 32,412) were analyzed. NDHRI was calculated by dividing cumulative nighttime heart rate area by daytime area. Generalized additive models (GAMs) explored the non-linear relationship between mean NDHRI and mortality, adjusting for confounders. Subgroup analyses were conducted based on ethnicity, ICU type, and comorbidities. A U-shaped association was observed between hospital mortality and mean NDHRI (P < 0.001). The optimal NDHRI range (40.0%-45.0%) demonstrated the lowest mortality rates. The duration spent within this range correlated inversely with mortality (P < 0.001). Subgroup analyses consistently supported these findings across diverse patient profiles. Our findings suggest an association between maintaining NDHRI within the 40.0%-45.0% range and lower mortality rates in critically ill patients, highlighting the potential utility of monitoring circadian heart rate variations in the ICU. Further research and future randomized controlled trials are essential to confirm causality and should consider this NDHRI range as a pivotal reference target.

Prevalence and outcome of elderly and low-risk patients with degenerative mitral regurgitation undergoing transcatheter edge-to-edge repair

AimThe aims of this study were: i) to report the prevalence of low-risk patients with degenerative mitral regurgitation (DMR) undergoing mitral transcatheter edge-to-edge repair (M-TEER) in a real-world setting; ii) to evaluate the prognostic significance of EuroSCORE II; iii) to determine whether an optimal M-TEER provides a mortality benefit regardless of EuroSCORE-II. MethodsWe analyzed data from the GIOTTO registry that enrolled patients undergoing M-TEER in Italy. We included only patients with DMR. Two groups were defined: patients with EuroSCORE<4% and with EuroSCORE≥4%. A further stratification according to variables included in the EuroSCORE-II was made. Interaction between EuroSCORE-II and optimal procedural success was evaluated. Outcome of interest was all-cause death at 2-year. ResultsAmong 1659 patients prospectively enrolled in the GIOTTO registry, 657 had DMR, 364 with an EuroSCORE<4% (53%) and 311 with an EuroSCORE≥4% (47%). Patients with lower EuroSCORE were older with less comorbidities. All-cause mortality was higher in patients with EuroSCORE≥ vs <4%. EuroSCORE II ≥ 4% was independently associated with an increased risk of mortality (HR 2.36, 95%CI 1.28–4.38, p = 0.007). Among variables included in the EuroSCORE-II, Left Ventricular Ejection Fraction<35% and systolic Pulmonary Artery Pressure ≥ 50mmhg were independent predictors of clinical outcome. Two-year all-cause death was higher in patients without optimal MR reduction regardless of the calculated surgical risk (p for interaction 0.3). ConclusionMore than half of patients with DMR undergoing M-TEER had a Euroscore<4% with a median age of 81. An optimally successful M-TEER was associated with a lower mortality regardless of EuroSCORE.

Time Trends and Geographic Patterns of Mortality Due to Tracheal, Bronchus, and Lung Cancer in Portugal

Tracheal, bronchus, and lung cancer (TBLC) remains a major public health concern. Knowledge about geographic patterns and time trends in TBLC could give insights to better address this problem. This study aimed to evaluate the geographic patterns and time trends in mortality due to TBLC observed in Portugal. TBLC-related deaths and population estimates (2011–2021) were derived from the Instituto Nacional de Estatística. Age-standardized mortality rates for people aged 50 or more (ASMR_50+) per 100,000 were obtained. Analyses were stratified by gender, geographic region, and level of urbanization. The time trends in ASMR_50+ were evaluated using joinpoint regression models, and the values for the annual percentage change (APC) and the respective 95% confidence interval (95% CI) were obtained. Differences in mortality due to TBLC between regions and levels of urbanization (2017–2021) were assessed through a standardized mortality ratio (SMR) and the respective 95% CI. In 2021, the ASMR_50+ per 100,000 inhabitants observed in mainland Portugal was 158.0 and 40.4 among men and women, respectively. According to the time-trend analysis, ASMR_50+ due to TBLC remained stable or described a downward trend among men, but there was an upward trend among women in suburban and urban regions. Observed deaths were significantly higher than the expected for men in urban areas (SMR = 125%; 95% CI: 121–128 and SMR = 118%; 95% CI: 115–122 in Norte and Lisboa, respectively), and women in Urban Norte (SMR = 125%; 95%CI: 119–131). Lower mortality than expected was observed among men living in Rural Norte and Rural Centro, as well as, among women living in all the rural areas. In suburban areas, the observed deaths were lower, higher, or as expected depending on the geographic region and gender. A notable upward trend in mortality due to TBLC among women was observed. The geographic patterns observed suggest the effects of deleterious environmental factors and smoking habits, deserving attention from policymakers.

Influence of Rurality When Accessing Emergency Healthcare During Exacerbation of Asthma

Background: Asthma is a significant contributor of respiratory illness throughout Australia, taking a toll on all genders and age groups. The rural healthcare workforce is currently undersupplied, and this worsens with the degree of rurality posing disadvantages in healthcare access. Lower asthma-related mortality rates in metropolitan cities than other areas of Australia indicate a need to explore the extent of the impact that residing rurally has on access to emergency healthcare for asthma-related emergencies. Methods: A scoping review of literature was conducted utilising the steps articulated in Peters et al. (2020)methodological approach. The databases: Cumulative Index to Nursing and Allied Health Literature (CINAHL), Emcare, Medline and PubMed were searched using key words. After screening 20 articles were included. Results: Four main themes emerged including the impact of access to resources; individual behaviours and attitudes; education and health literacy; and rural clinician adherence to guidelines. Conclusion: Several challenges are associated with living in rural areas which may impact patients ability to access emergency healthcare during an asthma-related emergency. Further research is recommended to determine the extent to which these challenges influence access to emergency healthcare and explore strategies to break down these barriers to ensure equitable emergency healthcare.

Education of postpartum hemorrhage management clinical skills among midwifery students in Malawi: A qualitative study

BackgroundUnskilled health professionals in healthcare systems are contributing to the high numbers of maternal mortality in Malawi. It is therefore essential that midwifery students acquire postpartum hemorrhage management clinical skills, especially in view of high maternal mortality, with postpartum hemorrhage being the leading cause. However, there is limited evidence on how the teaching is conducted with regard to students’ learning of postpartum hemorrhage management clinical skills. PurposeThis study aimed to describe the current teaching of postpartum hemorrhage management clinical skills in undergraduate nursing and midwifery program in Malawi. MethodsThe study applied a qualitative exploratory descriptive design. Data were collected through ten individual interviews with lecturers and three focus group discussions with twenty-four students in a midwifery education program in Malawi. The data were analyzed using thematic analysis. ResultsTwo themes emerged from the data analysis: (1) there are various teaching and learning approaches for postpartum hemorrhage management in use and (2) unpreparedness of midwifery students in postpartum hemorrhage management for patient care. ConclusionThe present study demonstrated that teaching of postpartum hemorrhage management clinical skills in an undergraduate nursing and midwifery programme in Malawi focuses on theoretical knowledge rather than practical skills, leaving midwifery students unprepared for postpartum hemorrhage management during clinical practice. The findings from the present study may provide knowledge guiding revision of the curriculum for the undergraduate nursing and midwifery programme in Malawi to consider global standards of midwifery education; enhance the lecturer to student ratio to provide the students with appropriate supervision; and to employ innovative teaching and learning strategies that promote peer education and skills practice among midwifery students. In addition, to conduct more research related to various teaching approaches in nursing and midwifery educational programs and among qualified midwives in Malawi. Statement of significancePostpartum hemorrhage management education in undergraduate nursing and midwifery programme in Malawi focuses more on theory than clinical skills. Improving midwifery students' acquisition of postpartum hemorrhage management clinical skills is needed to ultimately help lower Malawi's maternal mortality ratio.

Associations of global and specific components of positive psychological well-being with mortality risk: Findings from two cohort studies.

Previous studies have examined how various aspects of positive psychological well-being (PPWB) independently relate to healthy aging, yet a notable gap remains in understanding the effects of their overlap (i.e., shared variance). We used data from two longitudinal cohorts, the Midlife Development in the United States Study and the Health and Retirement Study (N = 3,302 and 7,209), each of which assessed hedonic and eudaimonic facets of PPWB (positive affect, purpose in life, personal growth, and self-acceptance) and tracked mortality status across 14-15 years of follow-up. We derived a global factor identifying elements common across PPWB facets and also specific PPWB factors from a bifactor model. Then, we examined if higher PPWB levels (global and specific) are associated with mortality risk. Across cohorts, higher global well-being factor levels were associated with reduced mortality risk, even after adjusting for a range of potential confounders. Fewer independent associations were evident with the specific PPWB factors. Findings suggest that variance common across hedonic and eudaimonic facets of PPWB is associated with lower mortality risk. Considering the shared versus unique effects of different PPWB facets can offer valuable insights for theorizing mechanisms underlying health benefits of PPWB and guiding decisions about intervention targets.

Impact of SGLT2 Inhibitors on Very Elderly Population with Heart Failure with Reduce Ejection Fraction: Real Life Data.

(1) Background: The validation of new lines of therapy for the elderly is required due to the progressive ageing of the world population and scarce evidence in elderly patients with HF with reduced ejection fraction (HFrEF). The purpose of our study is to analyze the effect of SGLT2 inhibitors (SGLT2i) in this subgroup of patients. (2) Methods: A single-center, real-world observational study was performed. We consecutively enrolled all patients aged ≥ 75 years diagnosed with HFrEF and for treatment with SGLT2i, and considered the theoretical indications. (3) Results: A total of 364 patients were recruited, with a mean age of 84.1 years. At inclusion, the mean LVEF was 29.8%. Median follow-up was 33 months, and there were 122 deaths. A total of 55 patients were under SGLT2i treatment. A multivariate Cox logistic regression test for all-cause mortality was performed, and only SGLT2i (HR 0.39 [0.19-0.82]) and glomerular filtration rate (HR 0.98 [0.98-0.99]) proved to be protective factors. In parallel, we conducted a propensity-score-matched analysis, where a significant reduction in all-cause mortality was associated with the use of SGLT2i treatment (HR 0.39, [0.16-0.97]). (4) Conclusions: Treatment with SGLT2i in elderly patients with HFrEF was associated with a lower rate of all-cause mortality. Our data show that SGLT2i therapy could improve prognosis in the elderly with HFrEF in a real-world study.

The Relationship Between Anemia and Parathyroid Hormone Levels in Patients With Kidney Failure Undergoing Hemodialysis Treatment in Georgia.

Chronic kidney disease (CKD) and its associated complications, such as anemia and secondary hyperparathyroidism (SHPT), pose significant challenges to global healthcare systems. This study explores the demographic and clinical characteristics of 284 kidney failure (KF) patients undergoing hemodialysis, in an effort to shed light on the possible association between anemia and SHPT. A proven connection between the two could theoretically influence the management plans for CKD patients, with the hopes of achieving lower morbidity and/or mortality in this patient group. A retrospective, cross-sectional, real-world data analytical study was conducted at a hemodialysis center in Tbilisi, Georgia, encompassing a sample size of n = 284 patients on maintenance hemodialysis. The data analyzed was extracted from patients' medical records. According to our results, the prevalence of anemia was strikingly high at 82.04%, underlining its substantial burden within this patient population.Our analysis revealed a notable systemic association between anemia and SHPT, particularly when considering hemodialysis vintage. However, our final analysis model revealed no statistically significant association between anemia and intact parathyroid hormone (iPTH) levels. Conclusion:Our study revealed a significant systemic relationship between anemia and SHPTwhen hemodialysis duration was considered, despite initial analyses showing no direct association. Future research should focus on longitudinal and multi-center studies to better understand this relationship, aiming to enhance the care and management of CKD patients on hemodialysis.

Public transport use and mortality among older adults in England: A cohort study

Background: Most evidence on transport use and mortality has focused on the commute to work. This study aims to fill a gap by assessing relationships between public transport use and mortality among older adults. Methods: Data come from a cohort of 10,186 individuals aged 50 or older who participated in the English Longitudinal Study of Ageing (ELSA), with survey data linked to mortality records over 16 years (2002–2018). We assessed a binary measure of public transport use and frequency of use from ‘every day or nearly every day’ to ‘never’. Cox proportional-hazards regression models were used to estimate hazard ratios (HRs) with 95% confidence intervals (CIs) for associations between public transport use and mortality. Analyses were adjusted for a range of covariates including socio-demographic factors, chronic disease, and self-reported problems with daily living activities. Results: Overall, 3371 participants (33.1%) died within the study period. Mortality was lower among public transport users (21.3%) compared with non-users (64.2%). Adjusted analyses found that users had 34% lower mortality than non-users (HR 0.66 (95% CI 0.61;0.71)). Adjusted analyses showed similar association sizes across frequencies of public transport use, with those using public transport every day or nearly every day having 41% lower mortality than never users (HR 0.59 (0.49;0.71)). Associations were similar among those with and without a longstanding illness. Conclusion: The use of public transport among older adults is linked to lower levels of mortality. Reductions in provision of public transport services could be detrimental to both transportation and population health.
