RESUMEN

Reducing under-five mortality is a crucial indicator of overall development in a country. However, in Angola, understanding the factors contributing to hospital deaths in this vulnerable demographic remains incomplete despite improvements in healthcare infrastructure and public health policies. With one of the highest under-five mortality rates in sub-Saharan Africa, Angola faces significant challenges such as malaria, malnutrition, pneumonia, neonatal conditions, and intestinal infectious diseases, which are the leading causes of death among children. This study aimed to identify factors associated with hospital deaths among children aged 28 days to five years admitted to DBPH in Luanda between May 2022 and June 2023. Using a hospital-based case-control design, the study included 1020 children, among whom 340 experienced hospital deaths. Distal and intermediate determinants emerged as primary predictors of hospital mortality, showing significant associations with: mother without schooling (OR [95%CI] 4.3 [1.2-15.7], p < 0.027); frequent alcohol consumption during pregnancy (OR [95%CI] 3.8 [2.5-5.9], p < 0.001); hospital stay ≤24 h (OR [95%CI] 13.8 [6.2-30.8], p < 0.001); poor nutritional status (OR [95%CI] 2.1 [1.4-3.2], p < 0.001); short interbirth interval (OR [95%CI] 1.7 [1.1-2.5], p < 0.014); maternal age ≤19 years (OR [95%CI] 5.6 [3.0-10.8], p < 0.001); and maternal age ≥35 years (OR [95%CI] 2.1 [1.2-3.7], p < 0.006). These findings highlight the preventable nature of most under-five hospital deaths and underscore the urgent need to address social inequities and improve the quality of primary healthcare services to effectively reduce child mortality in Angola.

RESUMEN

INTRODUCTION: The Veterans Health Administration (VHA) established the Airborne Hazards and Open Burn Pit Registry (AHOBPR) in 2014 to address exposure concerns for veterans who have served in military operations in Southwest Asia and Afghanistan. By 2021, over 236,086 veterans completed the online questionnaire and 60% requested an AHOBPR examination. Of those requesting an exam, only 12% had an exam recorded in their medical record. This article summarizes barriers and facilitators to delivering AHOBPR exams and shares lessons learned from facilities who have successfully implemented burn pit exams for veterans. MATERIALS AND METHODS: We (I.C.C and J.H.) constructed a key performance measure of AHOBPR examination (the ratio of examinations performed in facility over examinations assigned to a facility) to identify top performing facilities and then used stratified purposeful sampling among high-performing sites to recruit a diverse set of facilities for participation. We (P.V.C. and A.A.) recruited and interviewed key personnel at these facilities about their process of administering burn pit exams. Rapid qualitative methods were used to analyze interviews. RESULTS: The ratio of exams performed to exams assigned ranged from 0.00 to 14.50 for the 129 facilities with available information. Twelve interviews were conducted with a total of 19 participants from 10 different facilities. We identified 3 barriers: Unclear responsibility, limited incentives and competing duties for personnel involved, and constrained resources. Facilitators included the presence of an internal facilitator, additional staff support, and coordination across a facility's departments to provide care. CONCLUSIONS: Gaps across many VHA facilities to provide AHOBPR exams may be understood as stemming from organizational issues related to clear delegation of responsibility and staffing issues. VHA facilities that wish to increase AHOBPR exams for veterans may need additional administrative and medical staff.

RESUMEN

Like many Sub-Saharan countries, Angola struggles with a shortage of trained health professionals, especially for primary care. In 2021, the Angolan Ministry of Health in collaboration with the Angolan Medical Council launched the National Program for the Expansion of Family Medicine as a long-term strategy for the provision, fixation and training of family physicians in community health centres. Of the 425 residents 411 (96.7%) who entered the programme in 2021 will get their diplomas in the following months and will be certified as family physicians. Three main aspects make this National Programme unique in the Angolan context: (1) the common effort and engagement of the Ministry of Health with the Angolan Medical Council and local health authorities in designing and implementing this programme; (2) decentralisation of the training sites, with residents in all 18 provinces, including in rural areas and (3) using community health centres as the main site of practice and training. Despite this undeniable success, many educational improvements must be made, such as expanding the use of new educational resources, methodologies and assessment tools, so that aspects related to knowledge, practical skills and professional attitudes can be better assessed. Moreover, the programme must invest in faculty development courses aiming to create the next generation of preceptors, so that all residents can have in every rotation one preceptor or tutor responsible for the supervision of their clinical activities, case discussions and sharing their clinical duties, both at community health centres and municipal hospitals.

RESUMEN

Our goal was to determine the prevalence of anxiety and depression in a sample of U.S. military veterans with type 2 diabetes and elevated diabetes distress (DD). Cross-sectional analyses were conducted. The association between DD and anxiety and depression was assessed with logistic regression. Almost 80% of persons with elevated DD had clinically significant anxiety or depression symptoms. The odds of depression and anxiety increased with DD severity. Given the large overlap of depression and anxiety with elevated DD, we recommend providers screen for all three conditions and, if positive, connect to resources for diabetes self-management and/or clinical treatment.

RESUMEN

BACKGROUND: Obsessive compulsive disorder (OCD) is effectively treated with exposure and response prevention (ERP), yet very few veterans receive ERP for OCD within the Veterans Health Administration (VHA). Veterans are a clinically complex population, and no prior research has evaluated the effectiveness of ERP in veterans with OCD or comorbid OCD and posttraumatic stress disorder (PTSD). Given the limited accessibility of ERP-trained providers within VHA, assessment of video telehealth (VTH) delivery of ERP is warranted. METHODS: A sample of 160 veterans with OCD (80 diagnosed with comorbid PTSD) will be randomly assigned to receive up to 16 sessions of ERP or a stress management training control delivered via VTH. Assessments will occur at baseline, posttreatment, and 6-month follow-up. The primary outcome will evaluate the impact of ERP on participants' functioning, and secondary outcomes will include quality of life and OCD symptoms. At posttreatment, qualitative interviews with veterans, clinicians, and administrators will explore barriers and facilitators to treatment delivery, and the implementation potential of ERP. CONCLUSIONS: Results will provide direction for the treatment of OCD and comorbid PTSD in veterans, as well as guidance for future implementation efforts for ERP within VHA. CLINICALTRIALS: gov Identifier:NCT05240924.

RESUMEN

OBJECTIVE: The primary objective of this research was to assess the impact of a novel, peer-directed intervention (iNSPiRED) on diabetes distress (DD) among veterans with type 2 diabetes and DD. Secondary objectives were to assess iNSPiRED's impact on anxiety, depression, and diabetes self-management behaviors. METHOD: A single-blinded, randomized, parallel-group trial was conducted. Participants (n = 218) were recruited through a Veterans Affairs medical center and community agencies in a major metropolitan area from September 2019 through January 2022. Certified mental health peer specialists delivered iNSPiRED, a three-month goal-setting and resource navigation intervention. Outcomes were assessed at baseline, postintervention, and month six. Multilevel random-intercept linear regression models with treatment x time interaction terms were used to assess treatment effects. RESULTS: Frequency of following a healthy eating plan was higher for iNSPiRED vs usual care at month three relative to baseline (B = 0.58; p = 0.03) after adjusting for race and socioeconomic status. No other treatment effects differed significantly from zero (ps ≥ 0.05). CONCLUSION: Peer-directed interventions have the potential to deliver low-cost, highly scalable care. However, based on the largely negative findings of the current study, it is likely that more intense, multimodal interventions are needed to address DD.

RESUMEN

BACKGROUND: Black and Latinx adults experience disproportionate asthma-related morbidity and limited specialty care access. The severe acute respiratory syndrome coronavirus 2 pandemic expanded telehealth use. OBJECTIVE: To evaluate visit type (telehealth [TH] vs in-person [IP]) preferences and the impact of visit type on asthma outcomes among Black and Latinx adults with moderate-to-severe asthma. METHODS: For this PREPARE trial ancillary study, visit type preference was surveyed by e-mail or telephone post-trial. Emergency medical record data on visit types and asthma outcomes were available for a subset (March 2020 to April 2021). Characteristics associated with visit type preferences, and relationships between visit type and asthma outcomes (control [Asthma Control Test] and asthma-related quality of life [Asthma Symptom Utility Index]), were tested using multivariable regression. RESULTS: A total of 866 participants consented to be surveyed, with 847 respondents. Among the participants with asthma care experience with both visit types, 42.0% preferred TH for regular checkups, which associated with employment (odds ratio [OR] = 1.61; 95% confidence interval [CI], 1.09-2.39; P = .02), lower asthma medication adherence (OR = 1.06; 95% CI, 1.01-1.11; P = .03), and having more historical emergency department and urgent care asthma visits (OR = 1.10 for each additional visit; 95% CI, 1.02-1.18; P = .02), after adjustment. Emergency medical record data were available for 98 participants (62 TH, 36 IP). Those with TH visits were more likely Latinx, from the Southwest, employed, using inhaled corticosteroid-only controller therapy, with lower body mass index, and lower self-reported asthma medication adherence vs those with IP visits only. Both groups had comparable Asthma Control Test (18.4 vs 18.9, P = .52) and Asthma Symptom Utility Index (0.79 vs 0.84, P = .16) scores after adjustment. CONCLUSION: TH may be similarly efficacious as and often preferred over IP among Black and Latinx adults with moderate-to-severe asthma, especially for regular checkups. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02995733.

RESUMEN

ChatGPT, a chatbot based on a large language model, is currently attracting much attention. Modern machine learning (ML) architectures enable the program to answer almost any question, to summarize, translate, and even generate its own texts, all in a text-based dialogue with the user. Underlying technologies, summarized under the acronym NLP (natural language processing), go back to the 1960s. In almost all areas including medicine, ChatGPT is raising enormous hopes. It can easily pass medical exams and may be useful in patient care, diagnostic and therapeutic assistance, and medical research. The enthusiasm for this new technology shown even by medical professionals is surprising. Although the system knows much, it does not know everything; not everything it outputs is accurate either. Every output has to be carefully checked by the user for correctness, which is often not easily done since references to sources are lacking. Issues regarding data protection and ethics also arise. Today's language models are not free of bias and systematic distortion. These shortcomings have led to calls for stronger regulation of the use of ChatGPT and an increasing number of similar language models. However, this new technology represents an enormous progress in knowledge processing and dissemination. Numerous scenarios in which ChatGPT can provide assistance are conceivable, including in rhythmology. In the future, it will be crucial to render the models error-free and transparent and to clearly define the rules for their use. Responsible use requires systematic training to improve the digital competence of users, including physicians who use such programs.

RESUMEN

Radiofrequency ablation (RFA) is a minimally invasive cardiac catheterization procedure employed in patients whose atrial fibrillation (AF) is not well-controlled on medical therapy. While serious complications after the RFA are uncommon, we present the unique case of a 71-year-old male who suffered from acute respiratory distress syndrome (ARDS) and pneumomediastinum post-procedure. He presented to the ED with dyspnea, non-massive hemoptysis, and fever three days following RFA. Admission CT thorax demonstrated patchy ground glass opacities (GGOs) and stable fibrotic changes. He was admitted for suspected pneumonia, however, he failed to significantly improve on broad-spectrum antibiotics. Bronchoscopy found blood in proximal airways, however, lavage with serial aliquots were without worsening hemorrhage, ruling out suspected diffuse alveolar hemorrhage. Cytology resulted in rare iron polymorphonuclear neutrophils and no malignant cells. With worsening clinical status, the patient was eventually intubated. Repeat CT thorax showed new moderate pneumopericardium, small pneumomediastinum, and progressed GGOs. The respiratory course continued to worsen, and the patient passed away approximately one month after admission. We also present a brief literature review with the aim of identifying prognostic risk factors regarding post-RFA ARDS development. Additionally, this case identifies a novel complication of RFA, as post-procedural pneumomediastinum has not been previously described.

RESUMEN

The challenges posed by COVID-19's emergence have led to a search for its therapies. There is no cure for COVID-19 infection yet, but there is significant progress in vaccine formulation for prophylaxis and drug development (such as Paxlovid) for high-risk patients. As a contribution to the ongoing quest for solutions, this study shows potent phytocompounds identification as inhibitors of SARS-CoV-2 targets using in silico methods. We used virtual screening, molecular docking, and molecular dynamics (MD) simulations to investigate the interaction of some phytochemicals with 3CLpro, ACE2, and PLpro proteins crucial to the SARS-CoV-2 viral cycle. The predicted docking scores range from -5.5 to -9.4 kcal/mol, denoting appreciable binding of these compounds to the SARS-CoV-2 proteins and presenting a multitarget inhibition for COVID-19. Some phytocompounds interact favorably at non-active sites of the enzymes. For instance, MD simulation shows that an identified site on PLpro is stable and likely an allosteric region for inhibitor binding and modulation. These phytocompounds could be developed into effective therapy against COVID-19 and probed as potential multitarget-directed ligands and drug candidates against the SARS-CoV-2 virus. The study unveils drug repurposing, selectivity, allosteric site targeting, and multitarget-directed ligand in one piece. These concepts are three distinct approaches in the drug design and discovery pipeline.

RESUMEN

This study evaluated risk factors of sarcoidosis among Airborne Hazards and Open Burn Pit Registry (AHOBPR) participants using a retrospective age and sex-matched case-control design of AHOBPR participants deployed to Afghanistan or Southwest Asia with and without sarcoidosis diagnosed in the Veterans Health Administration (VHA). Logistic regression models tested for associations between sarcoidosis and self-reported cumulative deployment-related exposures. 661 Veterans (0.37%) were diagnosed with sarcoidosis in VHA. Logistic regression demonstrated lower odds of sarcoidosis in Hispanic participants (OR 0.08, CI 0.04-0.15) and those who served in the Navy (OR 0.40, CI 0.21-0.72). African American veterans (OR 2.27, CI 1.66-3.11) and former smokers (OR 1.87, CI 1.33-2.62) were at elevated risk. Of the exposure variables, convoy activities had the highest odds of being associated with sarcoidosis and was marginally statistically significant (OR 1.16, CI 1.00-1.35). Sarcoidosis was an uncommon diagnosis among AHOBPR participants and was associated with only one of eight assessed cumulative deployment-related exposures.

RESUMEN

BACKGROUND: The COVID-19 pandemic caused widespread changes to healthcare, but few studies focus on ambulatory care during the early phase of the pandemic. We characterize veterans' ambulatory care experience, specifically access and satisfaction, early in the pandemic. METHODS: We employed a semi-structured telephone interview to capture quantitative and qualitative data from patients scheduled with a primary care provider between March 1 - June 30, 2020. Forty veterans were randomly identified at a single large urban Veterans Health Administration (VHA) medical center. The interview guide utilized 56 closed and open-ended questions to characterize veterans' perceptions of access to and satisfaction with their primary care experience at VHA and non-VHA primary care sources. We also explored the context of veterans' daily lives during the pandemic. We analyzed quantitative data using descriptive statistics and verbatim quotes using a matrix analysis. RESULTS: Veterans reported completing more appointments (mean 2.6 (SD 2.2)) than scheduled (mean 2.3 (SD 2.2)) mostly due to same-day or urgent visits, with a shift to telephone (mean 2.1 (SD 2.2)) and video (mean 1.5 (SD 0.6)). Among those who reported decreased access to care early in the pandemic (n = 27 (67%)), 15 (56%) cited administrative barriers ("The phone would hang up on me") and 9 (33%) reported a lack of provider availability ("They are not reaching out like they used to"). While most veterans (n = 31 (78%)) were highly satisfied with their VHA care (mean score 8.6 (SD 2.0 on a 0-10 scale), 9 (23%) reported a decrease in satisfaction since the pandemic. The six (15%) veterans who utilized non-VHA providers during the period of interest reported, on average, higher satisfaction ratings (mean 9.5 (SD 1.2)). Many veterans reported psychosocial effects such as the worsening of mental health (n = 6 (15%)), anxiety concerning the virus (n = 12 (30%)), and social isolation (n = 8 (20%), "I stay inside and away from people"). CONCLUSIONS: While the number of encounters reported suggest adequate access and satisfaction, the comments regarding barriers to care suggest that enhanced approaches may be warranted to improve and sustain veteran perceptions of adequate access to and satisfaction with primary care during times of crisis.

RESUMEN

BACKGROUND: Service member exposure to explosive blast overpressure waves is common with considerable attention to traumatic brain injury (TBI) and neuropsychological sequalae. Less is known about the impacts on the respiratory system, particularly long-term effects, despite vulnerability to overpressure. Using a national registry, we previously observed an independent relationship between self-reported blast exposure and respiratory symptoms; however, the impact on objective measures of pulmonary function is poorly understood. METHODS: 307 Veterans referred to our national specialty center for post-deployment health concerns underwent a comprehensive multi-day evaluation that included complete pulmonary function testing (PFT), occupational and environmental medicine history, neuropsychological or psychological evaluation. We developed an a priori chart abstraction process and template to classify Veterans into blast exposure groups: (1) none, (2) single-mild, or (3) multiple-mild. This template focused primarily on clinician documented notes of blast related TBI that were used as proxy for blast overpressure injury to thorax. PFT variables characterizing flow (FEV1%; %∆FEV1), volume (TLC%), diffusion (DLCO%) and respiratory mechanics (forced oscillometry) were selected for analysis. RESULTS: Veterans (40.5 ± 9.7 years; 16.3% female) were referred 8.6 ± 3.6 years after their last deployment and presented with considerable comorbid conditions and health problems (e.g., 62% post-traumatic stress, 55% dyspnea). After chart abstraction, Veterans were assigned to none (n = 208), single mild (n = 52) and multiple mild (n = 47) blast exposure groups. Among the blast exposed, clinicians documented 73.7% were < 50 m from the blast and 40.4% were physically moved by blast. PFT outcome measures were similar across all groups (p value range: 0.10-0.99). CONCLUSIONS: In this referred sample of deployed Veterans, PFT measures of flow, volume, diffusion, and respiratory mechanics were not associated with clinician documented blast exposure per the retrospective chart abstraction methodology applied. Yet, these clinical findings suggest future research should determine and assess distinction between Veteran recollections of perceived blast experiences versus overpressure wave exposure to the respiratory system.

RESUMEN

Programming of implantable cardiac devices, especially dual-chamber pacemakers, can be challenging in daily clinical practice. Precise knowledge of programmable parameters is important; furthermore, one should also be familiar with the specific algorithms of each manufacturer. During programming, the patient's individual requirements should be taken into account, but out-of-the-box programming should be avoided. Another important goal of programming should be to stimulate as much as needed but as little as possible to provide the patient good exercise capacity while not being aware of the pacing. Manufacturers' algorithms can help reach these aims but need to be understood and-in case of inappropriate behavior-to be deactivated.

RESUMEN

Mitophagy and mitochondrial integrated stress response (ISR) are 2 primary protective mechanisms to maintain functional mitochondria. Whether these 2 processes are coordinately regulated remains unclear. Here we show that mitochondrial fission 1 protein (Fis1), which is required for completion of mitophagy, serves as a signaling hub linking mitophagy and ISR. In mouse hepatocytes, high fat diet (HFD) feeding induces unresolved oxidative stress, defective mitophagy and enhanced type I interferon (IFN-I) response implicated in promoting metabolic inflammation. Adenoviral-mediated acute hepatic Fis1 overexpression is sufficient to reduce oxidative damage and improve glucose homeostasis in HFD-fed mice. RNA-Seq analysis reveals that Fis1 triggers a retrograde mitochondria-to-nucleus communication upregulating ISR genes encoding anti-oxidant defense, redox homeostasis, and proteostasis pathways. Fis1-mediated ISR also suppresses expression of IFN-I-stimulated genes through activating transcription factor 5 (Atf5), which inhibits the transactivation activity of interferon regulatory factor 3 (Irf3) known to control IFN-I production. Metabolite analysis demonstrates that Fis1 activation leads to accumulation of fumarate, a TCA cycle intermediate capable of increasing Atf5 activity. Consequently, hepatic Atf5 overexpression or monomethyl fumarate (MMF) treatment improves glucose homeostasis in HFD-fed mice. Collectively, these results support the potential use of small molecules targeting the Fis1-Atf5 axis, such as MMF, to treat metabolic diseases.

RESUMEN

The diagnosis of paroxysmal tachycardia can be challenging in clinical practice because even with a typical patient history including palpitations, tachycardia, and an on/off phenomenon, 24 h Holter monitoring frequently fails to document the tachycardia. After unsuccessful 24 h Holter monitoring, we managed to document a very fast wide QRS complex tachycardia in a young patient by a mobile portable event monitor. Subsequent invasive electrophysiologic diagnostics followed by catheter ablation clarified the tachycardia mechanism and led to permanent elimination of the tachycardia.

RESUMEN

OBJECTIVE: To summarize the therapeutic effects and safety of biologics either approved or in clinical development for asthma, chronic obstructive pulmonary disease, urticaria, nasal polyps, atopic dermatitis, and eosinophilic esophagitis. This review attempts to provide some guidance when choosing among agents. DATA SOURCES: Recently published articles obtained through PubMed database searches including research articles, review articles, and case reports. STUDY SELECTIONS: PubMed database searches were conducted using the following keywords: biologics, asthma, COPD, urticaria, atopic dermatitis, food allergy, nasal polyps, and eosinophilic esophagitis. RESULTS: The approval of omalizumab by the Food and Drug Administration in 2003 for patients with asthma paved the way for the development of multiple biologics for a variety of respiratory and allergic diseases. Agents approved by the Food and Drug Administration include mepolizumab, reslizumab, benralizumab, and dupilumab, and several more are in the late stages of clinical development. Owing to the overlap in the pathogenesis of respiratory and allergic diseases, many of these biologics target multiple respiratory and allergic diseases simultaneously. CONCLUSION: The numerous biologic options have made the selection of the best biologic for each patient a potential conundrum for clinicians. Adequate point of care biomarkers to facilitate personalized medical therapy are generally lacking. Furthermore, although clinically effective and generally safe, none of the biologics discussed in this review have induced long-standing disease remission. Nevertheless, these agents have given us the opportunity to treat the most severe patients and to better understand the biology of respiratory and allergic diseases. As knowledgeable physicians, we should embrace and be educated on these novel therapies and the pathways they target.

RESUMEN

BACKGROUND: Intimate partner violence (IPV) refers to a violation of women's reproductive rights as it impacts on their sexual and reproductive health autonomy. AIM: In this study, we aimed at assessing the pattern of IPV and the socio-cultural determinants and predictors of partner violence in a rural community setting where the bulk of the abuse prevails. SETTING: This study was conducted in a rural community in Southern Nigeria. METHODS: This study employed a mixed method comprising seven focus group discussions (FGDs) and quantitative components. The cross-sectional survey was conducted amongst 209 ever married or cohabited females in 2018 using the World Health Organization (WHO) multi-country survey questionnaire adapted to the study objectives. Data analysis was conducted by using IBM SPSS v21.0. The level of significance was set at p 0.05. RESULTS: The overall IPV prevalence was 79.4%. The prevalence of partner's controlling behaviour, emotional IPV, physical IPV and sexual IPV was 62.6%, 55.98%, 49.3% and 2.6%, respectively. Membership of an interest group was protective against IPV (OR = 0.430, 95% CI = 0.193-0.957) whilst the belief that a good wife obeys her partner even if she disagrees (OR = 9.201, 95% CI = 1.299-65.194) and the belief that it is the wife's obligation to have sex with the husband even if she doesn't feel like (OR = 2.356, 95% CI = 1.049-5.288) were risk factors. CONCLUSION: The burden of IPV in the studied rural community is enormous. There should be public enlightenment to desensitise people regarding the erroneous views that encourage partner violence. We encourage women to become a part of social groups that can enhance their education and empowerment.
