Meta-Analysis
BACKGROUND
Together with environmental factors, intrinsic capacity (the composite of all the physical and mental capacities of an individual) has been proposed as a marker of healthy ageing. However, whether intrinsic capacity predicts major clinical outcomes is unclear. We aimed to explore the association of intrinsic capacity with functional decline and mortality in older adults.
METHODS
In this systematic review and meta-analysis, we conducted a systematic search in MEDLINE (via PubMed), Scopus, and Web of Science from database inception to Feb 14, 2024, of observational longitudinal studies conducted in older adults (age ≥60 years) assessing the association of intrinsic capacity with impairment in basic activities of daily living (BADL) or instrumental activities of daily living (IADL) or risk of mortality. Estimates were extracted by two reviewers (JLS-S and W-HL) and were pooled using three-level meta-analytic models. The quality of each study was independently assessed by two authors (JLS-S and PLV) using the Newcastle-Ottawa Scale for longitudinal studies. Heterogeneity was evaluated using the I indicator at two levels: within-study (level 2) and between-study (level 3) variation. For associations between intrinsic capacity and IADL and BADL, we transformed data (standardised β coefficients and odds ratios [ORs]) into Pearson product moment correlation coefficients (r) using Pearson and Digby formulas to allow comparability across studies. For associations between intrinsic capacity and risk of mortality, hazard ratios (HRs) with 95% CIs were extracted from survival analyses. This study is registered with PROSPERO, CRD42023460482.
FINDINGS
We included 37 studies (206 693 participants; average age range 65·3-85·9 years) in the systematic review, of which 31 were included in the meta-analysis on the association between intrinsic capacity and outcomes; three studies (2935 participants) were included in the meta-analysis on the association between intrinsic capacity trajectories and longitudinal changes in BADL or IADL. Intrinsic capacity was inversely associated with longitudinal impairments in BADL (Pearson's r -0·12 [95% CI -0·19 to -0·04]) and IADL (-0·24 [-0·35 to -0·13]), as well as with mortality risk (hazard ratio 0·57 [95% CI 0·51 to 0·63]). An association was also found between intrinsic capacity trajectories and impairment in IADL (but not in BADL), with maintained or improved intrinsic capacity over time associated with a lower impairment in IADL (odds ratio 0·37 [95% CI 0·19 to 0·71]). There was no evidence of publication bias (Egger's test p>0·05) and there was low between-study heterogeneity (I=18·4%), though within-study (I=63·2%) heterogeneity was substantial.
INTERPRETATION
Intrinsic capacity is inversely associated with functional decline and mortality risk in older adults. These findings could support the use of intrinsic capacity as a marker of healthy ageing, although further research is needed to refine the structure and operationalisation of this construct across settings and populations.

BACKGROUND
Ageing hallmarks, characterising features of cellular ageing, have a role in the pathophysiology of many age-related diseases. We examined whether obesity is associated with an increased risk of developing such hallmark-related diseases.
METHODS
In this multicohort study, we included people aged 38-72 years with data on weight, height, and waist circumference measured during a clinical examination at baseline between March 13, 2006, and Oct 1, 2010, from the UK Biobank with follow-up until Nov 12, 2021. To test reproducibility of the findings (replication analysis), we used data from people aged 40 years or older included in the Finnish Public Sector study and the Finnish Health and Social Support study who responded to the study surveys, had data on BMI, and were successfully linked to electronic health records from national registers up to Dec 31, 2016. Obesity and clinical characteristics were assessed at baseline. Via linkage to national health records, participants were followed up for 83 diseases related to nine ageing hallmarks (genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis, deregulated nutrient sensing, mitochondrial dysfunction, cellular senescence, stem cell exhaustion, and altered intercellular communication). Outcomes were the first instance of hallmark-related disease, in addition to co-occurrence of three or more hallmark-related diseases and mortality.
FINDINGS
496 530 adults (mean age 57·0 years [SD 8·1]) from the UK Biobank were included in the primary analysis, and 83 249 (mean age 48·2 years [6·4]) adults from the Finnish cohorts were included in the replication analysis. Median follow-up was 12·7 years (IQR 12·0-13·4) in the UK Biobank and 14·0 years (8·0-15·0) in the Finnish cohorts. After adjusting for demographic characteristics, lifestyle factors, and depression, UK Biobank participants with obesity (BMI ≥30·0 kg/m) had a 1·40 (95% CI 1·38-1·41) times higher hazard ratio for the first hallmark-related disease than those with a healthy weight (BMI 18·5-24·9 kg/m). The corresponding hazard ratios for three co-occurring diseases were 2·92 (95% CI 2·64-3·22) for deregulated nutrient sensing, 2·73 (2·46-3·02) for telomere attrition, 2·33 (2·10-2·60) for epigenetic alterations, 2·30 (2·14-2·48) for mitochondrial dysfunction, 2·23 (2·04-2·45) for stem cell exhaustion, 2·02 (1·89-2·16) for altered intercellular communication, 2·01 (1·89-2·15) for cellular senescence, 1·83 (1·67-2·00) for loss of proteostasis, and 1·39 (1·27-1·52) for genomic instability. These findings were replicated in the Finnish cohorts. In both studies, the associations between other risk factors (low education, unhealthy dietary factors [available only in the UK Biobank], smoking, high alcohol consumption, physical inactivity, and depression) and hallmark-related diseases were weaker than those with obesity. 45-60% of the excess mortality in people with obesity was attributable to hallmark-related diseases.
INTERPRETATION
Obesity might have an important role in the development of diseases associated with cellular ageing. Tackling ageing mechanisms could potentially help to reduce the disease and mortality burden resulting from the obesity epidemic.

BACKGROUND
Incidence of central venous catheter (CVC)-related thrombosis in critically ill patients remains ambiguous and its association with potential hazardous sequelae unknown. The primary aim of the study was to evaluate the epidemiology of CVC-related thrombosis; secondary aims were to assess the association of catheter-related thrombosis with catheter-related infection, pulmonary embolism and mortality.
METHODS
This was a single-center, prospective observational study conducted at a tertiary intensive care unit (ICU) in the Netherlands. The study population consisted of CVC placements in adult ICU patients with a minimal indwelling time of 48 h. CVC-related thrombosis was diagnosed with ultrasonography. Primary outcomes were prevalence and incidence, incidence was reported as the number of cases per 1000 indwelling days.
RESULTS
173 CVCs in 147 patients were included. Median age of patients was 64.0 [IQR: 52.0, 72.0] and 71.1 % were male. Prevalence of thrombosis was 0.56 (95 % CI: 0.49, 0.63) and incidence per 1000 indwelling days was 65.7 (95 % CI: 59.0, 72.3). No association with catheter-related infection was found (p = 0.566). There was a significant association with pulmonary embolism (p = 0.022). All 173 CVCs were included in the survival analysis. Catheter-related thrombosis was associated with a lower 28-day mortality risk (hazard ratio: 0.39, 95 % CI: 0.17, 0.87).
CONCLUSION
In critically ill patients, prevalence and incidence of catheter-related thrombosis were high. Catheter-related thrombosis was not associated with catheter-related infections, but was associated with pulmonary embolism and a decreased mortality risk.

Review
The effect of consultations performed by specialised nurses or advanced nurse practitioners on patient and organisational outcomes in patients with complex health conditions: An umbrella review.
BACKGROUND
Policymakers and researchers often suggest that nurses may play a crucial role in addressing the evolving needs of patients with complex conditions, by taking on advanced roles and providing nursing consultations. Nursing consultations vary widely across settings and countries, and their activities range from complementing to substituting traditional physician-led consultations or usual care.
OBJECTIVE
This study was aimed at describing the effects of nursing consultations with patients with complex conditions in any setting on patient outcomes (quality of life, physical status, psychosocial health, health behaviour, medication adherence, mortality, anthropometric and physiological outcomes, and patient satisfaction) and organisational outcomes (health resource use and costs).
DESIGN
Umbrella review.
METHODS
We followed the Joanna Briggs Institute method for umbrella reviews. We searched PubMed, Embase, Cochrane Database of Systematic Reviews and CINAHL to identify relevant articles published in English, Dutch, French, Spanish or German between January 2013 and February 2023. We included systematic literature reviews, with or without meta-analyses, that included randomised controlled trials conducted in high-income countries. Reviews were eligible if they pertained to consultations led by specialised nurses or advanced nurse practitioners. Article selection, data extraction and quality appraisal were performed independently by at least two reviewers.
RESULTS
We included 50 systematic reviews based on 473 unique trials. For all patient outcomes, nursing consultations achieved effects at least equivalent to those of physician-led consultations or usual care (i.e., non-inferiority). For quality of life, health behaviour, medication adherence, mortality and patient satisfaction, more than half the meta-analyses found statistically significant effects in favour of nursing consultations (i.e., superiority). Cost results must be interpreted with caution, because very few and heterogeneous cost-related data were extracted, and the methodological quality of the cost analyses was questionable. Narrative syntheses confirmed the overall conclusions of the meta-analyses.
CONCLUSIONS
The effects of nursing consultations on patients with complex health conditions across healthcare settings appear to be at least similar to physician-led consultations or usual care. Nursing consultations appear to be more effective than physician-led consultations or usual care in terms of quality of life, health behaviour, mortality, patient satisfaction and medication adherence. Further analysis of the primary data is necessary to determine the patient populations and settings in which nursing consultations are most effective. Moderate study quality, diversity amongst and within systematic reviews, and quality of reporting hamper the strength of the findings.

International Journal of Surgery Case... Jun 2024Bilateral tubal ectopic pregnancy (BTP) is a rare and potentially life-threatening condition that is, often challenging to diagnose preoperatively.
INTRODUCTION
Bilateral tubal ectopic pregnancy (BTP) is a rare and potentially life-threatening condition that is, often challenging to diagnose preoperatively.
PRESENTATION OF CASE
We present a case of BTP in a 25-year-old primigravid woman with a history of infertility due to polycystic ovarian syndrome. She was receiving letrozole when she presented with severe abdominal pain and vaginal bleeding. Initial evaluation revealed a ruptured ectopic pregnancy in the right fallopian tube, prompting an emergency laparotomy. During surgery, a second intact ectopic mass was discovered in the left fallopian tube, highlighting the diagnostic complexity of BTP. Management involved a salpingectomy on the right side and salpingostomy on the left to preserve fertility.
DISCUSSION
This case underscores the importance of considering BTP in the differential diagnosis of ectopic pregnancies and the necessity for thorough preoperative imaging studies, namely ultrasonography and surgical exploration, to prevent missed diagnoses.
CONCLUSION
BTP is a rare and challenging clinical entity that requires a comprehensive approach to diagnosis and management. Early recognition, prompt intervention, and close surveillance are essential to mitigate the risk of maternal morbidity and mortality associated with this condition.

BACKGROUND
Heatstroke (HS), associated with the early activation of the coagulation system and frequently presenting with thrombocytopenia, poses a significant healthcare challenge. Understanding the relationship of nadir platelet count (PLT) within 24 h for adverse outcomes in HS patients is crucial for optimizing management strategies.
METHODS
This retrospective cohort study, conducted in six tertiary care hospitals, involved patients diagnosed with HS and admitted to the emergency departments. The primary and secondary outcomes included in-hospital mortality and various acute complications, respectively, with logistic regression models utilized for assessing associations between nadir PLT and outcomes. The PLT count change curve was described using a generalized additive mixed model (GAMM), with additional analyses involving body temperature (BT) at 2 h also conducted.
RESULTS
Of the 152 patients included, 19 (12.5%) died in-hospital. The median nadir PLT within 24 h was 99.5 (58.8-145.0)*10^9/L. Notably, as a continuous variable (10*10^9/L), nadir PLT was significantly associated with in-hospital mortality (OR 0.76; 95% CI 0.64-0.91; P = 0.003) and other adverse outcomes like acute kidney and liver injury, even after adjustment for confounders. GAMM revealed a more rapid and significant PLT decline in the non-survival group over 24 h, with differential PLT dynamics also observed based on BT at 2 h.
CONCLUSIONS
Nadir PLT within 24 h were tied to in-hospital mortality and various adverse outcomes in HS patients. Early effective cooling measures demonstrated a positive impact on these associations, underscoring their importance in patient management.

OBJECTIVES
Early prediction of epileptic seizures can help reduce morbidity and mortality. In this work, we explore using electrocardiographic (ECG) signal as input to a seizure prediction system and note that the performance can be improved by using selected signal processing techniques.
METHODS
We used frequency domain analysis with a deep neural network backend for all our experiments in this work. We further analysed the effect of the proposed system for different seizure semiologies and prediction horizons. We explored refining the signal using signal processing to enhance the system's performance.
RESULTS
Our final system using the Temple University Hospital's Seizure (TUHSZ) corpus gave an overall prediction accuracy of 84.02 %, sensitivity of 87.59 %, specificity of 81.9 %, and an area under the receiver operating characteristic curve (AUROC) of 0.9112. Notably, these results surpassed the state-of-the-art outcomes reported using the TUHSZ database; all findings are statistically significant. We also validated our study using the Siena scalp EEG database. Using the frequency domain data, our baseline system gave a performance of 75.17 %, 79.17 %, 70.04 % and 0.82 for prediction accuracy, sensitivity, specificity and AUROC, respectively. After selecting the optimal frequency band of 0.8-15 Hz, we obtained a performance of 80.49 %, 89.51 %, 75.23 % and 0.89 for prediction accuracy, sensitivity, specificity and AUROC, respectively which is an improvement of 5.32 %, 10.34 %, 5.19 % and 0.08 for prediction accuracy, sensitivity, specificity and AUROC, respectively.
CONCLUSIONS
The seizure information in ECG is concentrated in a narrow frequency band. Identifying and selecting that band can help improve the performance of seizure detection and prediction.
SIGNIFICANCE
EEG is susceptible to artefacts and is not preferred in a low-cost ambulatory device. ECG can be used in wearable devices (like chest bands) and is feasible for developing a low-cost ambulatory device for seizure prediction. Early seizure prediction can provide patients and clinicians with the required alert to take necessary precautions and prevent a fatality, significantly improving the patient's quality of life.

OBJECTIVE
To estimate the health and economic burden of non-communicable diseases (NCDs) attributed to alcohol consumption in 2019 for the Brazilian Unified Health System (SUS) stratified by states.
STUDY DESIGN
Observational, descriptive, and ecological study.
METHODS
We used population attributable fractions (PAFs) of NCDs due to alcohol consumption from the Global Burden of Disease study. We applied the PAFs to the costs of hospitalizations and outpatient procedures of medium to high complexity paid by SUS for each outcome, obtained from official databases. We also calculated the disability-adjusted life years (DALYs) and mortality caused by alcohol-related NCDs. We converted the costs into international dollars (Int$) using the purchasing parity power in 2019.
RESULTS
Alcohol-related NCDs accounted for 8.48% of deaths and 7.0% of DALYs among men, and 1.33% of deaths and 1.6% of DALYs among women. The main diseases were substance use, digestive, and neoplastic diseases. The SUS spent Int$202.0 million on alcohol-related NCDs, mostly on hospitalizations. The highest health burden was observed in the states of the Northeast region, and the highest expenses in the states from the South. The burden and cost values varied by sex, age group, and state.
CONCLUSION
The study showed that alcohol consumption has a significant impact on Brazilian population morbidity and mortality and SUS expenditures, especially among men. These results can support policies for the prevention and control of alcohol consumption and health promotion at the subnational level, prioritizing strategies that are more appropriate to local realities.

Vaccination programs have proven successful in the prevention and control of infectious diseases among children on a global scale, but the majority of adult populations remain unvaccinated. immunocompromised adults as well as older adults aged low-income countries as Streptococcus pneumoniae infections are associated with substantial morbidity and mortality among 65 years and above. Despite the introduction of pneumococcal conjugate vaccines (PCVs), the burden of vaccine-type serotypes remains high in there are no clear policies for adult vaccination. As per the Global Burden of Disease 2019 report, about 120,000 individuals aged 70 years and older died as a result of LRTIs) in sub-Saharan Africa. A medical advisory board meeting was conducted in April 2022 to discuss the burden of pneumococcal diseases in adults, the current status of policies and practices of adult vaccination, unmet needs, and challenges in Ghana. This expert opinion paper outlines the pneumococcal epidemiology and burden of disease in Ghana, as well as the rationale for adult pneumococcal vaccination. It also highlights the potential barriers to adult vaccination and offers recommendations to overcome these obstacles and enhance vaccine acceptance in Ghana.

BACKGROUND AND AIMS
Chronic liver diseases belong to the most common diseases worldwide and are associated with increased morbidity and mortality. Although more than one in three adults are estimated to have metabolic dysfunction-associated steatotic liver disease (MASLD), awareness of this condition is low amongst the general public, health care professionals and policy makers. However, meaningful knowledge transfer is essential for raising awareness and improving prevention and treatment. This study set out to investigate the use of the major internet search engine to understand how knowledge transfer has evolved by analyzing liver-related searches trends.
METHODS
We investigated Google search trends by measuring the number of hits relating to liver diseases between 2004 and 2021 in seven languages and European countries but also worldwide. All analyses were performed in R using the R Google trends package gtrendsR.
RESULTS
We found that interest in MASLD [formerly non-alcoholic fatty liver disease (NAFLD)] has generally increased over time, but that interest in metabolic associated steatohepatitis (MASH) - the most severe form of MASLD - has decreased. Interest in viral hepatitis C has decreased, whereas the number of queries regarding viral hepatitis B have been stable but dominated by interest in vaccination for it. Recent medical developments (in viral hepatitis) did not lead to a noticeable change in overall search behavior. Users preferred searching using their native language and less complex medical terms and acronyms (e.g., fatty liver instead of NAFLD).
CONCLUSIONS
In the last two decades, Google search trends have followed the general development in the field of hepatology. Searches were dominated by non-experts and are not being rapidly influenced by novel scientific developments. Also, users preferred search terms in their native languages rather than English and tended to avoid complex medical search terms. Awareness and communication strategies around MASLD should consider these preferences when addressing the general public.
