Dynapenic abdominal obesity and activities of daily living disability among older adults residing in low- and middle-income countries.

BACKGROUND: Dynapenic abdominal obesity (DAO) may be associated with an increased risk of disability. However, to date, this has not been investigated in low- and middle-income countries (LMICs), while the mediators are largely unknown. AIMS: Therefore, we aimed to investigate the association between DAO and activities of daily living (ADL) disability, and to identify potential mediators among older adults from six LMICs. METHODS: Cross-sectional, nationally representative data from the WHO Study on global AGEing and adult health were analyzed. Data on 20,198 adults aged ≥ 60 years were analyzed [mean (SD) age 69.3 (13.1) years; 54.1% females]. Dynapenia was defined as handgrip strength of < 26 kg for men and < 16 kg for women. Abdominal obesity was defined as waist circumference of > 88 cm for women and > 102 cm for men. DAO was defined as having both dynapenia and abdominal obesity. Disability was defined as severe or extreme difficulty in conducting at least one of six types of ADL. Multivariable logistic regression and mediation analysis were conducted. RESULTS: Compared to no dynapenia and no abdominal obesity, DAO was significantly associated with 2.08 (95%CI = 1.37-3.17) times higher odds for ADL disability Mediation analysis showed that diabetes (mediated percentage 4.7%), hypertension (7.2%), and angina (7.7%) were significant mediators in the association between DAO and ADL disability. CONCLUSIONS: DAO was associated with increased odds for ADL disability among older adults from LMICs. Future longitudinal studies are warranted to assess temporal associations, and whether addressing or preventing DAO can impact on future occurrence of disability.

Machine Learning-Based Prediction of Neurodegenerative Disease in Patients With Type 2 Diabetes by Derivation and Validation in 2 Independent Korean Cohorts: Model Development and Validation Study.

BACKGROUND: Several machine learning (ML) prediction models for neurodegenerative diseases (NDs) in type 2 diabetes mellitus (T2DM) have recently been developed. However, the predictive power of these models is limited by the lack of multiple risk factors. OBJECTIVE: This study aimed to assess the validity and use of an ML model for predicting the 3-year incidence of ND in patients with T2DM. METHODS: We used data from 2 independent cohorts-the discovery cohort (1 hospital; n=22,311) and the validation cohort (2 hospitals; n=2915)-to predict ND. The outcome of interest was the presence or absence of ND at 3 years. We selected different ML-based models with hyperparameter tuning in the discovery cohort and conducted an area under the receiver operating characteristic curve (AUROC) analysis in the validation cohort. RESULTS: The study dataset included 22,311 (discovery) and 2915 (validation) patients with T2DM recruited between 2008 and 2022. ND was observed in 133 (0.6%) and 15 patients (0.5%) in the discovery and validation cohorts, respectively. The AdaBoost model had a mean AUROC of 0.82 (95% CI 0.79-0.85) in the discovery dataset. When this result was applied to the validation dataset, the AdaBoost model exhibited the best performance among the models, with an AUROC of 0.83 (accuracy of 78.6%, sensitivity of 78.6%, specificity of 78.6%, and balanced accuracy of 78.6%). The most influential factors in the AdaBoost model were age and cardiovascular disease. CONCLUSIONS: This study shows the use and feasibility of ML for assessing the incidence of ND in patients with T2DM and suggests its potential for use in screening patients. Further international studies are required to validate these findings.

National Trends in the Prevalence of Unmet Health Care and Dental Care Needs During the COVID-19 Pandemic: Longitudinal Study in South Korea, 2009-2022.

BACKGROUND: Although previous studies have investigated trends in unmet health care and dental care needs, most have focused on specific groups, such as patients with chronic conditions and older adults, and have been limited by smaller data sets. OBJECTIVE: This study aims to investigate the trends and relative risk factors for unmet health care and dental care needs, as well as the impact of the COVID-19 pandemic on these needs. METHODS: We assessed unmet health care and dental care needs from 2009 to 2022 using data from the Korea Community Health Survey (KCHS). Our analysis included responses from 2,750,212 individuals. Unmet health care or dental care needs were defined as instances of not receiving medical or dental services deemed necessary by experts or desired by patients. RESULTS: From 2009 to 2022, the study included 2,700,705 individuals (1,229,671 men, 45.53%; 673,780, 24.95%, aged 19-39 years). Unmet health care needs decreased before the COVID-19 pandemic; however, during the pandemic, there was a noticeable increase (ßdiff 0.10, 95% CI 0.09-0.11). Unmet dental care needs declined before the pandemic and continued to decrease during the pandemic (ßdiff 0.23, 95% CI 0.22-0.24). Overall, the prevalence of unmet dental care needs was significantly higher than that for unmet health care needs. While the prevalence of unmet health care needs generally decreased over time, the ß difference during the pandemic increased compared with prepandemic values. CONCLUSIONS: Our study is the first to analyze national unmet health care and dental care needs in South Korea using nationally representative, long-term, and large-scale data from the KCHS. We found that while unmet health care needs decreased during COVID-19, the decline was slower compared with previous periods. This suggests a need for more targeted interventions to prevent unmet health care and dental care needs.

Teriparatide in postmenopausal osteoporosis: uncovering novel insights into efficacy and safety compared to other treatments - a systematic review and meta-analysis.

Objective: The aim of the study was to evaluate the efficacy and safety of teriparatide compared to other treatments for postmenopausal osteoporosis. Methods: A review of studies from 2000 to January 2023 analyzed randomized controlled trials on postmenopausal women treated with teriparatide (PTH 1-34), comparing it to placebo or other osteoporosis treatments. The analysis focused on bone mineral density (BMD), bone turnover markers, and clinical outcomes, employing Review Manager 5.4.1 and the RoB 2 tool for bias assessment. Results: Our analysis of 23 randomized controlled trials (RCTs) found that PTH (134) treatment significantly increased lumbar spine BMD (mean difference (MD) = 0.02, 95% CI: 0.01-0.03) and femoral neck BMD (MD = 0.01, 95% CI: 0.00-0.01). However, there were no significant changes in total hip and radial bone BMD among the 3536 and 2046 participants, respectively. We also found that PTH (1-34) increased P1NP in a larger cohort (n = 1415) when compared to osteocalcin (n = 206). Although the risk of adverse events increased (relative risk (RR) = 1.65, 95% CI: 1.32-2.07), the incidence of fractures decreased significantly (RR = 0.57, 95% CI: 0.45-0.072), with no significant difference observed in mortality rates between treatment and control groups. Conclusion: Teriparatide improves lumbar spine and femoral neck BMD in postmenopausal women. Particularly notable is the novel finding regarding its effect on radius BMD, an area less explored in previous research. Despite an uptick in adverse events, the marked decrease in fracture incidence confirms its clinical utility for high-risk osteoporosis patients, highlighting the necessity for ongoing investigations into its full skeletal effects.

Risk factors, prevention and treatment of weight gain associated with the use of antidepressants and antipsychotics: a state-of-the-art clinical review.

INTRODUCTION: People with severe mental illness have poor cardiometabolic health. Commonly used antidepressants and antipsychotics frequently lead to weight gain, which may further contribute to adverse cardiovascular outcomes. AREAS COVERED: We searched MEDLINE up to April 2023 for umbrella reviews, (network-)meta-analyses, trials and cohort studies on risk factors, prevention and treatment strategies of weight gain associated with antidepressants/antipsychotics. We developed 10 clinical recommendations. EXPERT OPINION: To prevent, manage, and treat antidepressant/antipsychotic-related weight gain, we recommend i) assessing risk factors for obesity before treatment, ii) monitoring metabolic health at baseline and regularly during follow-up, iii) offering lifestyle interventions including regular exercise and healthy diet based on patient preference to optimize motivation, iv) considering first-line psychotherapy for mild-moderate depression and anxiety disorders, v)choosing medications based on medications' and patient's weight gain risk, vi) choosing medications based on acute vs long-term treatment, vii) using effective, tolerated medications, viii) switching to less weight-inducing antipsychotics/antidepressants where possible, ix) using early weight gain as a predictor of further weight gain to inform the timing of intervention/switch options, and x) considering adding metformin or glucagon-like peptide-1 receptor agonists, or topiramate(second-line due to potential adverse cognitive effects) to antipsychotics, or aripiprazole to clozapine or olanzapine.

Effects of antipsychotic treatment on cardio-cerebrovascular related mortality in schizophrenia: A subanalysis of a systematic review and meta-analysis with meta-regression of moderators.

To further explore the role of different antipsychotic treatments for cardio-cerebrovascular mortality, we performed several subgroup, sensitivity and meta-regression analyses based on a large previous meta-analysis focusing on cohort studies assessing mortality relative risk (RR) for cardio-cerebrovascular disorders in people with schizophrenia, comparing antipsychotic treatment versus no antipsychotic. Quality assessment through the Newcastle-Ottawa Scale (NOS) and publication bias was measured. We meta-analyzed 53 different studies (schizophrenia patients: n = 2,513,359; controls: n = 360,504,484) to highlight the differential effects of antipsychotic treatment regimens on cardio-cerebrovascular-related mortality in incident and prevalent samples of patients with schizophrenia. We found first generation antipsychotics (FGA) to be associated with higher mortality in incident samples of schizophrenia (oral FGA [RR=2.20, 95 %CI=1.29-3.77, k = 1] and any FGA [RR=1.70, 95 %CI=1.20-2.41, k = 1]). Conversely, second generation antipsychotics (SGAs) and clozapine were associated with reduced cardio-cerebrovascular-related mortality, in prevalent samples of schizophrenia. Subgroup analyses with NOS score ≥7 (higher quality) demonstrated a significantly increased cardio-cerebrovascular disorder-related mortality, among those exposed to FGAs vs SGAs. Meta-regression analyses demonstrated a larger association between antipsychotics and decreased risk of mortality with longer follow-up, recent study year, and higher number of adjustment variables. Overall, this subanalysis of a systematic review contributes to the evolving understanding of the complex role of antipsychotic treatment for cardio-cerebrovascular mortality in schizophrenia, paving the way for more targeted interventions and improved patient outcomes.

Prenatal and infant exposure to antibiotics and subsequent risk of neuropsychiatric disorders in children: A nationwide birth cohort study in South Korea.

We aimed to assess the association between antibiotic exposure in fetal and postnatal life (within six months after birth) and the risk of neuropsychiatric disorders in childhood. A nationwide, population-based birth cohort study(infants, n = 3,163,206; paired mothers, n = 2,322,735) was conducted in South Korea, with a mean follow-up duration of 6.8 years, using estimates of hazard ratio [HR] and 95 % confidence intervals (CIs). Following propensity score matching including the baseline variables, antibiotic exposure in both fetal (HR,1.07 [95 % CI, 1.05-1.08]) and postnatal life (1.05 [1.03-1.07]) was associated with an increased risk of overall childhood neuropsychiatric disorders. A synergistic effect was observed with prenatal and postnatal exposures (1.12 [1.09-1.15]). The risk increases with the increasing number and duration of prescriptions. Significant associations were found for both common (1.06 [1.05-1.08]) and severe outcomes (1.17 [1.09-1.26]), especially for intellectual disability (1.12 [1.07-1.17]), ADHD (1.10 [1.07-1.13]), anxiety (1.06 [1.02-1.11]), mood (1.06 [1.00-1.12]), and autism (1.03 [1.01-1.07]). When comparing siblings with different exposure statuses to consider familial factors, prenatal and postnatal exposure risk increased to 10 % (95 % CI, 6-12) and 12 % (7-17), respectively. Similar results were observed in the unmatched and health screening cohort, which considers maternal obesity, smoking, and breastfeeding. Based on these findings, clinicians may consider potential long-term risks when assessing the risk-benefit of early-life antibiotic prescription.

Risk Factors for Depression in Patients With Knee Osteoarthritis: A Systematic Review and Meta-analysis.

BACKGROUND: Knee osteoarthritis (KOA) is a widespread chronic condition. Depression frequently occurs among patients with KOA. The objective of this meta-analysis was to identify risk factors associated with comorbid depression in patients with KOA. MATERIALS AND METHODS: A comprehensive search of the PubMed/MEDLINE, Embase, Cochrane Library, and Web of Science databases was conducted for studies related to comorbid depression in patients with KOA. We conducted statistical analyses to obtain relevant results, followed by heterogeneity tests and assessment for publication bias. RESULTS: The prevalence of comorbid depression among patients with KOA was 34% (95% CI, 28%-41%). Notable risk factors linked to comorbid depression in patients with KOA included female sex (relative risk [RR], 1.17; 95% CI, 1.11-1.23), obesity (mean difference [MD], 1.30; 95% CI, 0.88-1.71), use of analgesics (RR, 1.50; 95% CI, 1.38-1.63), comorbidities (MD, 0.20; 95% CI, 0.10-0.31), unmarried or widowed status (RR, 1.72; 95% CI, 1.56-1.91), bilateral knee pain (RR, 1.38; 95% CI, 1.11-1.71), high total Western Ontario and Mc-Master Universities Arthritis Index (WOMAC) score (MD, 14.92; 95% CI, 10.02-19.82), high WOMAC pain score (MD, 5.76; 95% CI, 2.86-8.67), low gait velocity (MD, -0.12; 95% CI, -0.16 to -0.09), and extended duration in the Timed Up and Go Test (MD, 1.56; 95% CI, 0.87-2.25). CONCLUSION: Based on the current evidence, female sex, obesity, use of analgesics, comorbidities, unmarried or widowed status, bilateral knee pain, high total WOMAC score, high WOMAC pain score, low gait velocity, and prolonged time on the Timed Up and Go Test were identified as risk factors for depression in patients with KOA. Focus should be given to these aspects when preventing depression among these patients. [Orthopedics. 2024;47(5):e225-e232.].

Association between sedentary behavior and wish to die among adults aged ≥50 years: Findings from the Irish Longitudinal Study on Ageing.

We investigated the association between sedentary behavior (SB) and wish to die (WTD; i.e., feeling that one would be better off dead or wishing for one's own death), and the extent to which this can be explained by sleep problems, depression, anxiety, loneliness, perceived stress, and social network in a nationally representative sample of adults aged ≥50 years from Ireland. Cross-sectional data from Wave 1 of the Irish Longitudinal Study on Ageing 2009-2011 were analyzed. WTD was defined as answering affirmatively to the question "In the last month, have you felt that you would rather be dead?" SB was used as a continuous variable (hours/day), and also as a categorical (< or ≥8 h/day) variable. Multivariable logistic regression and mediation analyses were conducted. Data on 8163 adults aged ≥50 years were analyzed [mean (SD) age 63.6 (9.1) years; 48.0% males]. Overall, ≥8 (vs. <8) hours/day of SB was associated with a significant 2.04 (95%CI = 1.50-2.76) times higher odds for WTD, while a 1-h increase in SB per day was associated with 1.11 (95%CI = 1.06-1.16) times higher odds for WTD. Mediation analysis showed that sleep problems, depression, loneliness, perceived stress, and social network explained a modest proportion of the association between SB and WTD (mediated percentage 9.3%-14.8%). The present cross-sectional study found that increasing or higher levels of SB is positively associated with WTD. Addressing the identified potential mediators may reduce WTD among people who are sedentary. However, future longitudinal and intervention studies are needed to make concrete recommendations.

Comorbid health conditions in people with attention-deficit/hyperactivity disorders: An umbrella review of systematic reviews and meta-analyses.

BACKGROUND: We aimed to systematically review meta-analyses on the link between attention-deficit/hyperactivity disorder (ADHD) and a broad range of psychiatric, physical, and behavioral health conditions (PROSPERO; no.CRD42023448907). RESULTS: We identified 22 meta-analyses that included 544 primary studies, covering 76 unique conditions in over 234 million participants across 36 countries and six continents. We found high-certainty evidence for the associations between ADHD and neuropsychiatric conditions (bipolar disorders, personality disorders, schizophrenia, and pragmatic language skills), night awakenings, obesity, decayed incipient surfaces, asthma, astigmatism, hyperopia and hypermetropia, strabismus, and suicide ideation. Moderate-certainty evidence suggested that ADHD was associated with headache, mood/affective disorders, depression, bruxism, bone fractures, atopic rhinitis, vision problems, suicide attempts, completed suicide, and all-cause mortality. Low-certainty evidence indicated associations with eating disorders, sleep efficiency, type 2 diabetes, dental trauma prevalence, atopic diseases, and atopic dermatitis. Very low-certainty evidence showed associations between ADHD and several sleep parameters. CONCLUSION: We found varied levels of evidence for the associations of ADHD with multiple health conditions. Therefore, clinicians should consider a wide range of neurological, psychiatric, sleep and suicide-related, metabolic, musculoskeletal, oral, allergic, and visual conditions, as well as the increased risk of mortality when assessing individuals with ADHD.

Global public concern of childhood and adolescence suicide: a new perspective and new strategies for suicide prevention in the post-pandemic era.

BACKGROUND: Suicide is the second leading cause of death in young people worldwide and is responsible for about 52,000 deaths annually in children and adolescents aged 5-19 years. Familial, social, psychological, and behavioral factors play important roles in suicide risk. As traumatic events such as the COVID-19 pandemic may contribute to suicidal behaviors in young people, there is a need to understand the current status of suicide in adolescents, including its epidemiology, associated factors, the influence of the pandemic, and management initiatives. DATA SOURCES: We investigated global and regional suicide mortality rates among children and adolescents aged 5-19 years using data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. The suicide mortality rates from 1990 to 2019 were examined in 204 countries and territories across six World Health Organization (WHO) regions. Additionally, we utilized electronic databases, including PubMed/MEDLINE and Scopus, and employed various combinations of terms such as "suicide", "adolescents", "youth", "children", "risk factors", "COVID-19 pandemic", "prevention", and "intervention" to provide a narrative review on suicide within the pediatric population in the post-pandemic era. RESULTS: Despite the decreasing trend in the global suicide mortality rate from 1990 to 2019, it remains high. The mortality rates from suicide by firearms or any other specified means were both greater in males. Additionally, Southeast Asia had the highest suicide rate among the six WHO regions. The COVID-19 pandemic seems to contribute to suicide risk in young people; thus, there is still a strong need to revisit appropriate management for suicidal children and adolescents during the pandemic. CONCLUSIONS: The current narrative review integrates up-to-date knowledge on suicide epidemiology and the effects of the COVID-19 pandemic, risk factors, and intervention strategies. Although numerous studies have characterized trends in suicide among young people during the pre-pandemic era, further studies are required to investigate suicide during the pandemic and new strategies for suicide prevention in the post-pandemic era. It is necessary to identify effective prevention strategies targeting young people, particularly those at high risk, and successful treatment for individuals already manifesting suicidal behaviors. Care for suicidal children and adolescents should be improved with parental, school, community, and clinical involvement.

Is unicompartmental knee arthroplasty a better choice than total knee arthroplasty for unicompartmental osteoarthritis? A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: The choice of unicompartmental knee arthroplasty (UKA) vs. total knee arthroplasty (TKA) in the surgical treatment of knee osteoarthritis (KOA) remains controversial. This study aimed to perform a systematic review and meta-analysis of randomized controlled trials (RCTs) to compare the clinical results of UKA and TKA for treating unicompartmental KOA. METHODS: PubMed, Embase, and the Cochrane Library were systematically searched for articles published up to January 2, 2023. The literature was rigorously screened to include only RCTs comparing UKA and TKA for unicompartmental KOA. A systematic review and meta-analysis were performed to calculate the mean difference (MD), relative risk (RR), and 95% confidence interval (CI) according to the Cochrane standards. RESULTS: Thirteen publications involving 683 UKAs and 683 TKAs were analyzed. Except for one study with a follow-up period of 15 years, all outcome measures reported were within 5 years of follow-up. Meta-analysis showed better knee recovery (MD: 1.23; 95% CI: 1.01-1.45; P <0.00001), greater knee function (MD: 1.78; 95% CI: 0.34-3.22; P = 0.02), less pain (MD: 0.75; 95% CI: 0.43-1.06; P <0.00001), and better health status (MD: 3.75; 95% CI: 0.81-6.69; P = 0.01) after UKA than TKA. However, considering the minimal clinically important difference values for these variables, the findings were not clinically relevant. Moreover, UKA patients had fewer complications (RR: 0.59; 95% CI: 0.45-0.78; P = 0.0002) and shorter hospital stays (MD: -0.89; 95% CI: -1.57 to -0.22; P = 0.009) than did TKA patients. There were no statistically significant differences in terms of postoperative range of movement, revision, failure, operation time, and patient satisfaction. CONCLUSIONS: In terms of clinical efficacy, there was no obvious advantage of UKA over TKA in the surgical treatment of knee OA when considering the minimal clinically important difference. The main advantage of UKA over TKA is that it leads to fewer complications and a shorter length of hospital stay. It is ideal to perform prospective studies with longer follow-up periods to fully evaluate the long-term efficacy and safety of the two procedures in the future.

Association between depression and incident dementia: Longitudinal findings from the share study.

BACKGROUND: The association between depression and dementia is still unclear, particularly regarding depression as a potential risk factor preceding dementia. Therefore, we aimed to verify if the presence of depression at baseline may increase the risk of dementia and cognitive impairment during 15 years of follow-up in the SHARE (Survey of Health, Aging and Retirement in Europe) study. METHODS: Depressive symptoms were defined using the EURO-D, with a score ≥4 indicative of depression. Incident dementia was ascertained using self-reported data and caregivers' information, cognitive impairment using objective cognitive tests. Cox regression analysis, adjusted for 10 baseline confounders, was run and hazard ratios (HRs), with their 95% confidence intervals, were estimated. RESULTS: In total 22,789 participants were included in the present analysis (mean age 64.2 years) and were predominantly female. The prevalence of depression at baseline was 24.9%. Over 15 years of follow-up, the onset of dementia occurred a median 2 years earlier in people with depression compared to those without. Depression at the baseline significantly increased the risk of dementia in the overall sample (HR = 1.74; 95% CI: 1.54-1.95) and the risk of cognitive impairment (HR = 1.15; 95% CI: 1.06-1.25). For dementia, the association was stronger in people less than 60 years (HR = 2.07; 95% CI: 1.42-3.02) than in participants aged ≥80 years (HR = 1.47; 95% CI: 1.14-1.91). A similar trend was observed for cognitive impairment. Among the single items of the EURO-D, loss of concentration was the strongest individual variable predicting the onset of dementia. CONCLUSIONS: Depression increased the risk of dementia and cognitive impairment, particularly in younger adults, whereas loss of concentration was the strongest individual predicting variable of dementia. These findings demonstrate the need for early detection of depression for preventing future cognitive worsening.

Mild Cognitive Impairment and Suicidal Ideation Among Adults Aged 65 Years or Older From Low- and Middle-Income Countries.

OBJECTIVES: Mild cognitive impairment (MCI) is a unique indicator of underlying distress that may be strongly associated with suicide risk. Despite this, to date, no study has examined the association between MCI and suicidal ideation. Therefore, the present study aimed to examine the association between MCI and suicidal ideation among adults aged ≥65 years from 6 low- and middle-income countries (LMICs; China, Ghana, India, Mexico, Russia, and South Africa). METHODS: Cross-sectional, nationally representative data from the World Health Organization's Study on Global Ageing and Adult Health were analyzed. MCI was defined using the National Institute on Aging-Alzheimer's Association criteria. Self-reported information on past 12-month suicidal ideation was collected. Multivariable logistic regression and meta-analysis were conducted to assess associations. RESULTS: Data on 13,623 individuals aged ≥65 years were analyzed. The prevalence of suicidal ideation ranged from 0.5% in China to 6.0% in India, whereas the range of the prevalence of MCI was 9.7% (Ghana) to 26.4% (China). After adjustment for potential confounders, MCI was significantly associated with 1.66 (95% confidence interval [95% CI] = 1.12-2.46) times higher odds for suicidal ideation. DISCUSSION: Mild cognitive impairment was significantly associated with higher odds for suicidal ideation among older adults in LMICs. Future longitudinal studies from LMICs are necessary to assess whether MCI is a risk factor for suicidal ideation.

Efficacy and safety of zoledronic acid in the treatment of osteoporosis: A meta-analysis of randomized controlled trials.

Purpose: Zoledronic acid can inhibit the activity of osteoclasts, and thus, may slow or inhibit bone loss. The purpose of this study was to systematically evaluate the efficacy and safety of zoledronic acid in the treatment of osteoporosis. Methods: Four databases, PubMed, Embase, Cochrane Library, and Web of Science, were systematically searched up to December 26, 2022. The primary outcomes included bone mineral density (BMD), carboxy-terminal cross-linked telopeptide of type 1 collagen (CTX), bone-specific alkaline phosphatase (BSAP), procollagen type 1 N-terminal prope-ptide (P1NP), adverse events, and fracture. Secondary outcomes included serum sclerostin level, Visual Analogue Scale (VAS) score, and Oswestry Disability Index (ODI). Results: A total of 22 randomized controlled trials were included in this meta-analysis. Meta-analysis results showed that zoledronic acid was effective in increasing BMD of the lumbar spine, femoral neck, trochanter and serum sclerostin level; and reduced CTX, BSAP, P1NP, VAS score, and ODI in patients with osteoporosis. Regarding safety, zoledronic acid could reduce the incidence of fractures but had relatively more adverse events. Conclusion: Zoledronic acid can significantly improve BMD of the lumbar spine, femoral neck and trochanter, and effectively reduce incidence of fracture in patients with osteoporosis, thereby significantly improving patients' quality of life. However, the incidence of adverse events was higher than that of patients treated with placebo.

National and Regional Trends in the Prevalence of Hypertension in South Korea Amid the Pandemic, 2009-2022: Nationwide Study of Over 3 Million Individuals.

BACKGROUND: Understanding the association between hypertension prevalence and socioeconomic and behavioral variables during a pandemic is essential, and this analysis should extend beyond short-term trends. OBJECTIVE: This study aims to examine long-term trends in the prevalence of participants diagnosed with and receiving treatment for hypertension, using data collected by a nationally representative survey from 2009 to 2022, which includes the COVID-19 pandemic era. METHODS: A nationwide, population-based, cross-sectional study used data collected from the South Korea Community Health Survey between 2009 and 2022. The study sample comprised 3,208,710 Korean adults over a period of 14 years. We aimed to assess trends in the prevalence of participants diagnosed with and receiving treatment for hypertension in the national population from 2009 to 2022, with a specific focus on the COVID-19 pandemic, using weighted linear regression models. RESULTS: Among the included 3,072,546 Korean adults, 794,239 (25.85%) were aged 19-39 years, 1,179,388 (38.38%) were aged 40-59 years; 948,097 (30.86%) were aged 60-79 years, and 150,822 (4.91%) were aged 80 years or older. A total of 1,426,379 (46.42%) were men; 761,896 (24.80%) and 712,264 (23.18%) were diagnosed with and received treatment for hypertension, respectively. Although the overall prevalence over the 14-year period increased, the upward trends of patients diagnosed with and receiving treatment for hypertension decreased during the COVID-19 pandemic era compared with the prepandemic era (ß difference for trend during vs before the pandemic -.101, 95% CI -0.107 to -0.094 vs -.133, 95% CI -0.140 to -0.127). Notably, the trends in prevalence during the pandemic were less pronounced in subgroups of older adults (≥60 years old) and individuals with higher alcohol consumption (≥5 days/month). CONCLUSIONS: This nationwide representative study found that the national prevalence of participants diagnosed with and receiving treatment for hypertension increased during the prepandemic era. However, there was a marked decrease in these trends during the prepandemic era, compared with the pandemic era, particularly among specific subgroups at increased risk of negative outcomes. Future studies are needed to evaluate the factors associated with changes in the prevalence of hypertension during the COVID-19 pandemic.

Association between self-reported visual symptoms (suggesting cataract) and self-reported fall-related injury among adults aged ≥ 65 years from five low- and middle-income countries.

BACKGROUND: Cataracts may increase risk for falls but studies on this topic from low- and middle-income countries (LMICs) are scarce. Therefore, we examined the cross-sectional association between self-reported visual symptoms (suggesting cataract) and self-reported injurious falls in nationally representative samples of adults aged ≥ 65 years from five LMICs (China, Ghana, India, Mexico, and Russia). METHODS: Data from the WHO Study on global AGEing and adult health (SAGE) were analysed. Self-reported information on past 12-month fall-related injury and cataract based on symptoms were collected. Multivariable logistic regression and meta-analyses were conducted to assess associations. RESULTS: Data on 13,101 people aged ≥ 65 years were analysed [mean (SD) age 72.5 (11.3) years; 45.2% males]. The overall prevalence of self-reported fall-related injury and visual symptoms (suggesting cataract) were 4.9% and 29.4%, respectively. There was a positive association between self-reported visual symptoms (suggesting cataract) and fall-related injury (i.e., OR > 1) in all five countries but statistical significance was reached in three: China (OR = 1.60; 95% CI = 1.08-2.35), India (OR = 1.96; 95% CI = 1.15-3.35), and Russia (OR = 3.58; 95% CI = 2.06-6.24). The pooled OR including all five countries based on a meta-analysis was OR = 1.88 (95% CI = 1.32-2.68). CONCLUSIONS: Self-reported visual symptoms (suggesting cataract) were associated with higher odds for self-reported injurious falls among older adults in LMICs. Expanding availability of cataract surgery in LMICs may also have the additional benefit of reducing falls among older people.

National trends in sexual intercourse and usage of contraception among Korean adolescents.

BACKGROUND: The exact influence of the COVID-19 pandemic on sexual intercourse and usage of contraception remains largely uncharted territory. To bridge this gap in knowledge, we conducted a comprehensive, cross-sectional examination of long-term trends in the prevalence of sexual intercourse and usage of contraception among South Korean adolescents from 2006 to 2022. METHODS: In our research, we drew upon data encompassing 1,138,799 South Korean adolescents aged 12 to 18 years, derived from the Korean Youth Risk Behavior Web-based Survey (KYRBS) over a period spanning from 2006 to 2022. We focused on the prevalence of sexual intercourse, contraception utilization, and the underlying associated factors among this demographic. The KYRBS data was collected using a complex sampling strategy to determine the national prevalence estimates and shifts in prevalence before (2006-2019) and during (2020-2022) the COVID-19 pandemic era. RESULTS: During the pre-pandemic period, a decrease in adolescent sexual intercourse was observed (6.34% in 2006, 5.53% in 2012, and 5.87% in 2019). However, in the post-pandemic period (2020-2022), there was a surge in sexual intercourse (4.55% in 2020 and 6.20% in 2022). This evident alteration in sexual intercourse trajectory between pre- and post-pandemic periods was statistically significant [ßdiff, 0.950; 95% confidence interval (CI), 0.756-1.144]. Regarding contraceptive use among South Korean adolescents, there was an increase in the pre-COVID-19 pandemic phase across all demographic segments (14.61% in 2006, 22.30% in 2012, and 47.69% in 2022) but a notable decline when compared with the pre- and post-pandemic periods (ßdiff, - 0.319; 95% CI, - 0.454 to - 0.184). Additionally, during the study period, a decrease in sexual intercourse was observed in the pre-pandemic period (ß, - 0.129; 95% CI, - 0.148 to - 0.110), followed by an increase in the post-pandemic period (ß, 0.821; 95% CI, 0.627 to 1.014). This shift is highlighted by an effect size of 0.96 [weighted odds ratio (wOR); 95% CI, 0.92 to 1.00], indicating a substantial change in adolescent sexual behaviors across study periods. CONCLUSIONS: The increase in sexual intercourse and decrease in usage of contraception observed in our study between the pre- and post-COVID-19 periods suggests a potential threat to sexual health among South Korean adolescents. This trend emphasizes the ongoing necessity of raising awareness about adolescent sexual behavior in South Korea.

Short- and long-term neuropsychiatric outcomes in long COVID in South Korea and Japan.

We investigated whether SARS-CoV-2 infection is associated with short- and long-term neuropsychiatric sequelae. We used population-based cohorts from the Korean nationwide cohort (discovery; n = 10,027,506) and the Japanese claims-based cohort (validation; n = 12,218,680) to estimate the short-term (<30 days) and long-term (≥30 days) risks of neuropsychiatric outcomes after SARS-CoV-2 infection compared with general population groups or external comparators (people with another respiratory infection). Using exposure-driven propensity score matching, we found that both the short- and long-term risks of developing neuropsychiatric sequelae were elevated in the discovery cohort compared with the general population and those with another respiratory infection. A range of conditions including Guillain-Barré syndrome, cognitive deficit, insomnia, anxiety disorder, encephalitis, ischaemic stroke and mood disorder exhibited a pronounced increase in long-term risk. Factors such as mild severity of COVID-19, increased vaccination against COVID-19 and heterologous vaccination were associated with reduced long-term risk of adverse neuropsychiatric outcomes. The time attenuation effect was the strongest during the first six months after SARS-CoV-2 infection, and this risk remained statistically significant for up to one year in Korea but beyond one year in Japan. The associations observed were replicated in the validation cohort. Our findings contribute to the growing evidence base on long COVID by considering ethnic diversity.

Impact of the 2008 economic crisis on the burden of hepatitis B and C diseases in Southern European countries.

BACKGROUND: The economic crisis that began in 2008 has severely affected Southern (Greece, Italy, Portugal, Spain) Western European (SWE) countries of Western Europe (WE) and may have affected ongoing efforts to eliminate viral hepatitis. This study was conducted to investigate the impact of the economic crisis on the burden of HBV and HCV disease. METHODS: Global Burden of Diseases 2019 data were used to analyse the rates of epidemiological metrics of HBV and HCV acute and chronic infections in SWE and WE. Time series modelling was performed to quantify the impact of healthcare expenditure on the time trend of HBV and HCV disease burden in 2000-2019. RESULTS: Declining trends in incidence and prevalence rates of acute HBV (aHBV) and chronic HBV were observed in SWE and WE, with the pace of decline being slower in the post-austerity period (2010-2019) and mortality due to HBV stabilised in SWE. Acute HCV (aHCV) metrics and chronic HCV incidence and mortality showed a stable trend in SWE and WE, whereas the prevalence of chronic HCV showed an oscillating trend, decreasing in WE in 2010-2019 (p < 0.001). Liver cancer due to both hepatitis infections showed a stagnant burden over time. An inverse association was observed between health expenditure and metrics of both acute and chronic HBV and HCV. CONCLUSIONS: Epidemiological metrics for HBV and HCV showed a slower pace of decline in the post-austerity period with better improvement for HBV, a stabilisation of mortality and a stagnant burden for liver cancer due to both hepatitis infections. The economic crisis of 2008 had a negative impact on the burden of hepatitis B and C. Elimination of HBV and HCV by 2030 will be a major challenge in the SWE countries.
