Predictors of moderate to severe obstructive sleep apnea in patients with lung cancer.

BACKGROUND AND OBJECTIVES: OSA is a known medical condition that is associated with several comorbidities and affect patients' quality of life. The association between OSA and lung cancer remains debated. Some studies reported increased prevalence of OSA in patients with lung cancer. We aimed to assess predictors of moderate-to-severe OSA in patients with lung cancer. METHODS: We enrolled 153 adult patients who were newly diagnosed with lung cancer. Cardiorespiratory monitoring was performed using home sleep apnea device. We carried out Univariate and multivariate logistic regression analysis on multiple parameters including age, gender, smoking status, neck circumference, waist circumference, BMI, stage and histopathology of lung cancer, presence of superior vena cava obstruction, and performance status to find out the factors that are independently associated with a diagnosis of moderate-to-severe OSA. RESULTS: Our results suggest that poor performance status is the most significant predictor of moderate to severe OSA in patients with lung cancer after controlling for important confounders. CONCLUSION: Performance status is a predictor of moderate to severe OSA in patients with lung cancer in our population of middle eastern ethnicity.

Burden of obstructive sleep apnea in patients with lung cancer and its effect on performance status.

The association between lung cancer and obstructive sleep apnea has remained a matter of debate for years. Obstructive sleep apnea is thought to increase the incidence of lung cancer due to intermittent hypoxaemia and sleep fragmentation. The aim of this study is to assess the prevalence of obstructive sleep apnea in patients with lung cancer and its effect on those patients' performance status. This is a prevalence study that was conducted at Chest Diseases Department, Alexandria Main University Hospitals. We enrolled 153 patients with lung cancer. All patients underwent cardiorespiratory monitoring using a home sleep-testing device. Performance status was assessed using Karnofsky performance status scale. The study included 120 (78.4%) males and 33 (21.6%) females newly diagnosed with lung cancer. The mean age was 59.98 ± 11.11 years. Obstructive sleep apnea (apnea-hypopnea index ≥ 5) was present in 134 (87.6%) patients. Eighty-five (63.4%) patients had mild obstructive sleep apnea, 39 (29.1%) patients had moderate obstructive sleep apnea, and 10 (7.46%) patients had severe obstructive sleep apnea. Prolonged nocturnal oxygen desaturation as demonstrated by time of oxygen saturation spent below 90% (T90%) during total sleep time > 30% was present in 25 (16.3%) patients. There was a significant difference in the median value of Karnofsky performance status scale between patients with lung cancer and associated obstructive sleep apnea and those without obstructive sleep apnea. In conclusion, obstructive sleep apnea is highly prevalent among patients with lung cancer. Performance status is worse among patients with lung cancer in the presence of obstructive sleep apnea. Screening patients with lung cancer for obstructive sleep apnea is important regardless of the presence of classical symptoms of obstructive sleep apnea.

Assessing the relationship between food insecurity and lifestyle behaviors among university students: a comparative study between Lebanon and Germany.

BACKGROUND: Food insecurity is a common public health problem in both developed and developing countries. This study aimed to profile food insecurity among university students in a developed country with stable economic circumstances (Germany) and a developing Mediterranean country undergoing a severe economic and financial crisis (Lebanon) and examine the associations between food insecurity and lifestyle behaviors (i.e., physical activity, sleep, and adherence to a healthy eating pattern, such as the Mediterranean diet), stress, and financial well-being. METHOD: This online cross-sectional study was conducted between September 2021 and March 2022. Subjects were recruited through social media platforms (Facebook, WhatsApp, Instagram, and personal email) and in-class announcements by several university professors of various majors and from different universities in Lebanon and Germany. The final sample included 547 participants (197 from Lebanon and 350 from Germany). RESULTS: Our findings showed a higher food insecurity rate in Lebanon compared with Germany (59% versus 33%). In the bivariate analysis, food insecurity was associated with insomnia (r = 0.230; p < 0.001) and stress (r = 0.225; p = 0.001); German university students had higher physical activity (p < 0.001), better diet quality (p < 0.001), and lower adherence to the Mediterranean diet (p < 0001) than Lebanese students. In the multivariable analyses, more stress was related to insomnia (B = 0.178; p < 0.001), while financial well-being was not associated with any of the lifestyle behaviors. Physical activity, insomnia, and Mediterranean diet adherence were not associated with the country or food insecurity (p > 0.05); however, living in Germany was associated with better diet quality (B = -7.85; p < 0.001). CONCLUSION: The high prevalence of food insecurity reported in this study is alarming, particularly among Lebanese students; German students had better diet quality and higher physical activity but worse adherence to the Mediterranean diet. Moreover, food insecurity was also associated with worse sleep and stress. Further studies are necessary to assess the role of food insecurity as a mediating factor between sociodemographic characteristics and lifestyle behaviors.

Association between the bi-dimensional aspect of orthorexia and healthy behaviors among lebanese adolescents.

BACKGROUND: Recently, there has been a blooming focus on "eating healthy and clean", with the ideal of being healthy becoming a popular lifestyle trend. Previous research suggested the presence of two forms of orthorexia: Orthorexia Nervosa (OrNe) and Healthy Orthorexia (HeOr). Taking into consideration that orthorexia thoughts are led by the desire to reach an optimal physical health, the dedication to a healthy living may require healthy lifestyle habits: smoking cessation, moderate alcohol intake, and increased physical activity. The main study aim was to determine, among Lebanese adolescents, the association between healthy behaviors and the two likely forms of orthorexia (OrNe and HeOr), given that the adolescent phase is a risky period in the development of eating disorders. METHODS: A cross-sectional study, conducted between January and April 2022, enrolled 444 adolescents aged between 14 and 18 years, with an equitable random sample from all the Lebanese governorates (mean age 16.23 ± 1.15 years; 60.1% females). The Teruel Orthorexia Scale (TOS) was used to assess orthorexic eating tendencies. The Lebanese Waterpipe Dependence Scale, the Fagerström Test for Nicotine Dependence and the Alcohol Use Disorder Identification Test scales, all validated in adolescents, were used to evaluate the association between orthorexia and healthy behaviors. RESULTS: Higher TOS OrNe scores were significantly and highly correlated with the TOS HeOr scores (r = 0.68; p < 0.001). In the bivariate analysis, waterpipe smoking was weakly but significantly associated with more OrNe, whereas more physical activity was significantly and moderately associated with more HeOr. After adjusting over all sociodemographic characteristics, other behaviors and the other dimension of orthorexia, more alcohol use disorder was significantly but strongly associated with higher OrNe, whereas more physical activity remained significantly associated with higher HeOr. CONCLUSION: In light of our results, OrNe and HeOr might be considered as different entities, mainly in their associations with alcohol consumption and physical activity. This supports the hypothesis of OrNe being a new form of eating disorder, whereas HeOr possibly showing protective characteristics. Orthorexia is still a topic of controversy, especially in the probable presence of two facets that are still difficult to differentiate.

The development process of economic evaluation guidelines in low- and middle-income countries: a systematic review.

OBJECTIVES: To review the development of economic evaluation guidelines (EEGs) in low- and middle-income countries (LMICs), with the goal of assisting those developing EEGs in LMICs. METHODS: We conducted a systematic search in MEDLINE (Ovid), PubMed, EconLit, Embase (Ovid), the Cochrane Library, and the gray literature until March 2021. We extracted data on the methods used in the EEG development process, the responsible party engaged, and the development team's composition. We conducted a quality assessment, using the Appraisal of Guidelines for Research and Evaluation-Health Systems tool, and then carried out a relative comparison. RESULTS: Fourteen EEGs and nine studies were identified. In ten countries, the Ministry of Health was responsible for handling the development process. The majority of LMICs who developed EEGs did not explicitly report the discipline of those involved in the process. The developers of EEGs followed four main steps: conducting a review on national guidelines, organizing workshops, and getting support from international experts or from organizations. One-third of the identified EEGs failed to engage multisectoral or multidisciplinary developers, and approximately 14 percent did not follow or report any recommended step. CONCLUSIONS: This study identified a scarcity of published information related to the development process and the suboptimal quality of included studies. It provides relevant material to support international organizations and developers of guidelines in LMICs in developing EEGs that fit their national context. In addition, this paper recommends a transparent approach to the design of guidelines and to reporting on the methods for developing them.

The healthcare costs of antimicrobial resistance in Lebanon: a multi-centre prospective cohort study from the payer perspective.

BACKGROUND: Our aim was to examine whether the length of stay, hospital charges and in-hospital mortality attributable to healthcare- and community-associated infections due to antimicrobial-resistant bacteria were higher compared with those due to susceptible bacteria in the Lebanese healthcare settings using different methodology of analysis from the payer perspective . METHODS: We performed a multi-centre prospective cohort study in ten hospitals across Lebanon. The sample size consisted of 1289 patients with documented healthcare-associated infection (HAI) or community-associated infection (CAI). We conducted three separate analysis to adjust for confounders and time-dependent bias: (1) Post-HAIs in which we included the excess LOS and hospital charges incurred after infection and (2) Matched cohort, in which we matched the patients based on propensity score estimates (3) The conventional method, in which we considered the entire hospital stay and allocated charges attributable to CAI. The linear regression models accounted for multiple confounders. RESULTS: HAIs and CAIs with resistant versus susceptible bacteria were associated with a significant excess length of hospital stay (2.69 days [95% CI,1.5-3.9]; p < 0.001) and (2.2 days [95% CI,1.2-3.3]; p < 0.001) and resulted in additional hospital charges ($1807 [95% CI, 1046-2569]; p < 0.001) and ($889 [95% CI, 378-1400]; p = 0.001) respectively. Compared with the post-HAIs analysis, the matched cohort method showed a reduction by 26 and 13% in hospital charges and LOS estimates respectively. Infections with resistant bacteria did not decrease the time to in-hospital mortality, for both healthcare- or community-associated infections. Resistant cases in the post-HAIs analysis showed a significantly higher risk of in-hospital mortality (odds ratio, 0.517 [95% CI, 0.327-0.820]; p = 0.05). CONCLUSION: This is the first nationwide study that quantifies the healthcare costs of antimicrobial resistance in Lebanon. For cases with HAIs, matched cohort analysis showed more conservative estimates compared with post-HAIs method. The differences in estimates highlight the need for a unified methodology to estimate the burden of antimicrobial resistance in order to accurately advise health policy makers and prioritize resources expenditure.

Economic evaluation guidelines in low- and middle-income countries: a systematic review.

OBJECTIVES: To systematically identify the latest versions of official economic evaluation guidelines (EEGs) in low- and middle-income countries (LMICs) and explore similarities and differences in their content. METHODS: We conducted a systematic search in MEDLINE (Ovid), PubMed, EconLit, Embase (Ovid), the Cochrane Library, and the gray literature. Using a predefined checklist, we extracted the key features of economic evaluation and the general characteristics of EEGs. We conducted a comparative analysis, including a summary of similarities and differences across EEGs. RESULTS: Thirteen EEGs were identified, three pertaining to lower-middle-income countries (Bhutan, Egypt, and Indonesia), nine to upper-middle-income countries (Brazil, China, Colombia, Cuba, Malaysia, Mexico, Russian Federation, South Africa, and Thailand), in addition to Mercosur, and none to low-income countries. The majority (n = 12) considered cost-utility analysis and health-related quality-of-life outcome. Half of the EEGs recommended the societal perspective, whereas the other half recommended the healthcare perspective. Equity considerations were required in ten EEGs. Most EEGs (n = 11) required the incremental cost-effectiveness ratio and recommended sensitivity analysis, as well as the presentation of a budget impact analysis (n = 10). Seven of the identified EEGs were mandatory for pharmacoeconomics submission. Methodological gaps, contradictions, and heterogeneity in terminologies used were identified within the guidelines. CONCLUSION: As the importance of health technology assessment is increasing in LMICs, this systematic review could help researchers explore key aspects of existing EEGs in LMICs and explore differences among them. It could also support international organizations in guiding LMICs to develop their own EEGs and improve the methodological framework of existing ones.

Barriers and facilitators to implementation of essential health benefits package within primary health care settings in low-income and middle-income countries: A systematic review.

BACKGROUND: One of the key requirements for achieving universal health coverage is the proper design and implementation of essential health benefits package (EHPs). We systematically reviewed the evidence on barriers and facilitators to the implementation of EHPs within primary health care settings in low-income and middle-income countries. METHODS: We searched multiple databases and the gray literature. Two reviewers completed independently and in duplicate data selection, data extraction, and quality assessment. We synthesized the findings according to the following health systems arrangement levels: governance, financial, and delivery arrangements. RESULTS: Ten studies met the eligibility criteria. At the governance level, key reported barriers were insufficient policymaker-implementer interactions, limited involvement of consumers and stakeholders, sub-optimal primary health care network arrangement, poor marketing and promotion of package, and insufficient coordination with community network. The key reported facilitator was the presence of a legal policy framework for package implementation. At the financial level, barriers included delays and inadequate remunerations to health care providers while facilitators included government and donor commitments to financing of package and flexibility in exploring new funding mechanisms. At the delivery level, barriers included inadequate supervision, poor facility infrastructure, limited availability of equipment and supplies, and shortages of workers. Facilitators included proper training and management of workforce, availability of female health workers, presence of clearly defined packages, and continuum of care, including referrals to promote comprehensive service delivery. CONCLUSION: We identified a set of barriers and facilitators that need to be addressed to ensure proper implementation of EHPs within primary health care settings.

Direct Medical Cost of Hospitalization for Acute Stroke in Lebanon: A Prospective Incidence-Based Multicenter Cost-of-Illness Study.

Stroke is a major social and health problem posing heavy burden on national economies. We provided detailed financial data on the direct in-hospital cost of acute stroke care in Lebanon and evaluated its drivers. This was an observational, quantitative, prospective, multicenter, incidence-based, bottom-up cost-of-illness study. Medical and billing records of stroke patients admitted to 8 hospitals in Beirut over 1 year were analyzed. Direct medical costs were calculated, and cost drivers were assessed using a multivariable linear regression analysis. In total, 203 stroke patients were included (male: 58%; mean age: 68.8 ± 12.9 years). The direct in-hospital cost for all cases was US$1 413 069 for 2626 days (US$538 per in-hospital day). The average in-hospital cost per stroke patient was US$6961 ± 15 663. Hemorrhagic strokes were the most costly, transient ischemic attack being the least costly. Cost drivers were hospital length of stay, intensive care unit length of stay, type of stroke, stroke severity, modified Rankin Scale, third party payer, surgery, and infectious complications. Direct medical cost of acute stroke care represents high financial burden to Lebanese health system. Development of targeted public health policies and primary prevention activities need to take priority to minimize stroke admission in future and to contain this cost.

Economic evaluations of interventions to manage hyperphosphataemia in adult haemodialysis patients: A systematic review.

Managing hyperphosphataemia in haemodialysis patients is resource-intensive. A search for cost-effective interventions in this field is needed to inform decisions on the allocation of healthcare resources. NHSEED, MEDLINE, EMBASE and CINAHL were searched for full economic evaluations of hyperphosphataemia-managing interventions in adult haemodialysis patients, published between 2004 and 2014, in English, French, Dutch or German. Incremental cost-effectiveness ratios of the interventions were up-rated to 2013US$ using Purchasing Power Parity conversion rates and Consumer Price Indices. The quality of included studies was assessed using the Extended Consensus on Health Economic Criteria List. Twelve out of the 1681 retrieved records fulfilled the inclusion criteria. They reported only on one aspect of hyperphosphataemia management, which is the use of phosphate binders (calcium-based and calcium-free, in first-line and sequential use). No economic evaluations of other phosphorus-lowering interventions were found. The included articles derived from five countries and most of them were funded by pharmaceutical companies. The incremental cost-effectiveness ratios of phosphate binders ranged between US$11 461 and US$157 760 per quality-adjusted life-year gained. Calcium-based binders (especially calcium acetate) appear to be the optimal cost-effective first- and second-line therapy in prevalent patients, while the calcium-free binder, lanthanum carbonate, might provide good value for money, as second-line therapy, in incident patients. The studies' overall quality was suboptimal. Drawing firm conclusions was not possible due to the quality heterogeneity and inconsistent results. Future high-quality economic evaluations are needed to confirm the findings of this review and to address other interventions to manage hyperphosphataemia in this population.

Cost-effectiveness of phosphate binders among patients with chronic kidney disease not yet on dialysis: a long way to go.

Hyperphosphatemia management is integral to the management of patients with chronic kidney disease. This mineral abnormality is associated with greater costs, but so is its management, especially with the use novel phosphate binders. The economic evaluation of these pharmaceutical agents is increasingly needed to provide evidence for value of money spent and inform resource allocation. Recently, Nguyen et al. explored the economical attractiveness of Sevelamer relative to Calcium Carbonate among patients with chronic kidney disease not yet on dialysis and concluded that the former was cost-effective. The current commentary discusses the results of this analysis and sheds light on the methodological challenges of economic evaluations in this field.

Orthorexia nervosa in dietitians and dietetics students-prevalence, risk factors, and interventions: a scoping review using a systematic approach.

CONTEXT: Orthorexia nervosa (ON) is characterized by compulsive behaviors and increased concerns about healthful eating. Dietitians appear to be especially vulnerable to ON, and it is still debatable whether the disordered eating behaviors motivate individuals to enroll in nutrition programs, or whether these behaviors result from an exaggerated preoccupation with healthy eating triggered during their nutrition studies. OBJECTIVE: The aim was to provide an overview of the present state of knowledge about the prevalence, risk factors, and interventions addressing ON among dietitians and dietetics students. More specifically, it was examined whether dietitians and dietetics students differ from students attending different education programs or other health professionals with regard to the severity and risk factors of ON, and whether the extent of ON changes during the progression in the nutrition education years of study. DATA SOURCES: MEDLINE (Ovid), PubMed, EMBASE (Ovid), PsycInfo (EBSCO), CINAHL (EBSCO), Cochrane, ProQuest Central, CABI, ProQuest Dissertations, Google Scholar, ScienceDirect, and SpringerLink were searched on May 8, 2021, and updated on November 12, 2022. DATA EXTRACTION: Records were screened for eligibility; study characteristics, methodology, and findings of included articles were extracted; and the methodological quality assessed using the AXIS tool. Each step was preceded by a calibration exercise and conducted independently and in duplicate by pairs of 2 reviewers. Any disagreements were resolved through discussions. DATA ANALYSIS: A narrative synthesis was performed, whereby the characteristics, methodologies, and results of included studies were compared. CONCLUSIONS: Results were inconclusive; yet, a general status of the relatively "high" prevalence of ON among dietitians and dietetics students was established, stressing the need for systematic research to understand and mitigate orthorexic tendencies in this group. It is still too early to answer questions pertaining to prevalence, risk factors, interventions, and differences between dietetics students and other majors when it comes to severity and progress of ON throughout the continuing years of study, or between dietitians and other professional groups.

Developing the Lebanese health economic evaluation guideline.

OBJECTIVE: To report on the process of developing the Lebanese Economic Evaluation Guideline (LEEG), and to provide relevant material that could assist guideline developers in the future. METHODS: The development of the LEEG closely followed the process proposed by the World Health Organization, i.e. to set up a Guideline Development Group (composed of three Lebanese experts), to establish the rationale for developing the guideline in Lebanon, to identify its scope, to search and retrieve evidence through two systematic reviews, to assess and present the evidence, to translate the evidence into guidelines and recommendations through a deliberative process, and to consult international experts. The deliberative process included a survey, an in-person interview, and a consensus workshop with 16 Lebanese key stakeholders. Data was collected and quantitative analysis was conducted using SPSS software. International experts from Maastricht University - The Netherlands were consulted for issuing the LEEG. Supported by the Lebanese Ministry of Public Health (MoPH), the LEEG will be available for public consultation on the MoPH's webpage, and a final version will be made available thereafter. CONCLUSION: Clear and transparent reporting of the guideline development process should support international organizations as well as other developers in establishing their guidelines within their national context.

Health-related quality of life and utilities among Lebanese patients with Multiple Sclerosis: A cross-sectional study.

OBJECTIVE: This study assessed the Health-Related Quality of Life (HRQoL) and utilities of Multiple Sclerosis (MS) patients in Lebanon using generic and MS-specific QoL instruments, categorized by disease severity, and explored factors associated with HRQoL. METHODS: This was a cross-sectional, retrospective HRQoL study collecting data through face-to-face interviews using the EQ-5D-5 L and the Multiple Sclerosis International Quality of Life (MusiQoL) questionnaires. We enrolled Lebanese patients aged ≥18 years, diagnosed with MS for >6 months. Patients were categorized by disease severity using the expanded disability status scale (EDSS) scores: 0-3 (mild MS), 4-6.5 (moderate MS), and 7-9 (severe MS). Bivariate and linear regression analyses were performed to study factors associated with HRQoL. RESULTS: A total of 210 patients (mean age: 43.3 years; 65.7 % females) were included. The mean EQ-5D-5 L utility score was 0.74. This score decreased significantly with disease severity (p < 0.001 for the trend): 0.93, 0.60, and 0.32 for mild, moderate, and severe MS, respectively. The mean MusiQoL global index score was 71.33 and was significantly lower for severe MS (58.68), than for moderate (65.23) and mild (77.80), (p < 0.001 for the trend). Higher educational level, lower EDSS scores, and longer disease duration were associated significantly with a higher EQ-5D-5 L utility (R2 = 0.67), while employment, lower EDSS scores, and decrease in cognitive difficulties were associated with better MusiQoL utility (R2 = 0.46). CONCLUSIONS: This study reveals a significant and gradual deterioration in HRQoL as MS progresses, resulting in low utility scores for patients with severe MS.

Therapeutic targeting of cellular senescence in diabetic macular edema: preclinical and phase 1 trial results.

Compromised vascular endothelial barrier function is a salient feature of diabetic complications such as sight-threatening diabetic macular edema (DME). Current standards of care for DME manage aspects of the disease, but require frequent intravitreal administration and are poorly effective in large subsets of patients. Here we provide evidence that an elevated burden of senescent cells in the retina triggers cardinal features of DME pathology and conduct an initial test of senolytic therapy in patients with DME. In cell culture models, sustained hyperglycemia provoked cellular senescence in subsets of vascular endothelial cells displaying perturbed transendothelial junctions associated with poor barrier function and leading to micro-inflammation. Pharmacological elimination of senescent cells in a mouse model of DME reduces diabetes-induced retinal vascular leakage and preserves retinal function. We then conducted a phase 1 single ascending dose safety study of UBX1325 (foselutoclax), a senolytic small-molecule inhibitor of BCL-xL, in patients with advanced DME for whom anti-vascular endothelial growth factor therapy was no longer considered beneficial. The primary objective of assessment of safety and tolerability of UBX1325 was achieved. Collectively, our data suggest that therapeutic targeting of senescent cells in the diabetic retina with a BCL-xL inhibitor may provide a long-lasting, disease-modifying intervention for DME. This hypothesis will need to be verified in larger clinical trials. ClinicalTrials.gov identifier: NCT04537884 .

Patterns and Determinants of Weight Gain among People Who Use Drugs Undergoing Treatment for Recovery in Lebanon.

Substance use disorder compromises the nutritional status and the eating habits of drug users, often leading to malnutrition. Once referred for treatment, hyperphagia and poor lifestyle practices leading to weight gain are observed. This study aimed to examine the patterns and extent of weight change as well as the determinants of weight gain in a sample of drug users who were receiving treatment in Lebanon. A total of 172 male participants undergoing either rehabilitation or opioid substitution treatment (OST) were included. Multivariate regression analysis was applied to assess the effect of different variables on weight gain while adjusting for potentially confounding variables. Approximately two-thirds (65.1%) of the participants gained weight (OST: 54.3%, rehabilitation: 78.2%; p < 0.05). The mean weight gain was 5.9 kg and was mainly reported among participants in the underweight, normal, and overweight pre-treatment categories and accentuated in the rehabilitation group (OST: 2 kg, Rehabilitation: 10.6 kg). Around half of the participants moved from the normal weight category to the overweight and obese categories during treatment. Weight gain was negatively associated with the number of previous treatment attempts (Odds Ratio = 0.86; Confidence Interval: 0.74-0.99), duration of current treatment (Odds Ratio = 0.98; Confidence Interval: 0.96-0.99), and pre-treatment body mass index (BMI) (Odds Ratio = 0.88; Confidence Interval: 0.80-0.96). Investigating other nutrition and lifestyle practices, neither nutrition knowledge, food addiction, physical activity level, nor sleep quality were associated with weight gain. Treatment through drug use was associated with meaningful weight gain that might lead to health risk factors. Developing health promotion programs is crucial to enhance treatment and decrease the risk of relapse.

Association between Serum Vitamin D and Metabolic Syndrome in a Sample of Adults in Lebanon.

The evidence on the association between vitamin D and metabolic syndrome (MetS) is inconclusive. This was a cross-sectional study to explore the relationship between vitamin D serum levels and MetS in a sample of Lebanese adults (n = 230), free of diseases that affect vitamin D metabolism, recruited from an urban large university and neighboring community. MetS was diagnosed according to the International Diabetes Federation criteria. A logistic regression analysis was performed taking MetS as the dependent variable, and vitamin D was forced into the model as an independent variable. The covariates included sociodemographic, dietary, and lifestyle variables. The mean (SD) serum vitamin D was 17.53 (12.40) ng/mL, and the prevalence of MetS was 44.3%. Serum vitamin D was not associated with MetS (OR = 0.99 (95% CI: 0.96, 1.02), p < 0.757), whereas the male sex, compared with the female sex and older age, was associated with higher odds of having MetS (OR = 5.92 (95% CI: 2.44, 14.33), p < 0.001 and OR = 1.08 (95% CI: 1.04, 1.11), p < 0.001, respectively). This result adds to the controversy in this field. Future interventional studies are warranted to better understand the relationship between vitamin D and MetS and metabolic abnormalities.

Prevalence of medication administration errors in hospitalized adults: A systematic review and meta-analysis up to 2017 to explore sources of heterogeneity.

Previous estimates to meta-analyze administration error rates were limited by the high statistical heterogeneity, restricting their use. This study aimed to investigate sources of heterogeneity in pooled administration error rates in hospitalized adults. We systematically searched scientific databases up to November 2017 for studies presenting error rates/relevant numerical data in hospitalized adults. We conducted separate meta-analyses for the numerators: One Medication Error (OME) (each dose can be correct or incorrect) and Total Number of Errors (TNE) (more than one error per dose could be counted), using the generic inverse variance with a 95% confidence interval. Heterogeneity was assessed using the I2 and Cochran's Q test. We meta-analyzed 33 studies. The global pooled analyses based on the OME and TNE numerators showed very high heterogeneity (I2  = 100%; p < 0.00001). For each meta-analysis, subgroup analyses based on study characteristics (countries, wards, population, routes of administration, error detection methods, and medications) yielded results with consistently elevated heterogeneity. Beyond these characteristics, we stratified the studies according to the mean error prevalence level as the threshold. Based on the OME numerator, we identified two subgroups of low (0.15[0.13-0.17]; I2  = 0%; p = 0.43) and high (0.26[0.24-0.27]; I2  = 38%; p = 0.17) pooled prevalence rates, with controlled heterogeneity. Similarly, for the TNE numerator, we identified two subgroups of low (0.10[0.09-0.10]; I2  = 0%; p = 0.76) and high (0.28[0.27-0.29]; I2  = 0%; p = 0.89) pooled prevalence rates, with controlled heterogeneity. These subgroups differed regarding the denominators used: Total opportunities for errors versus others (doses, observations, administrations). Calculation methods, specifically the denominator, seem a primary factor in explaining heterogeneity in error rates. Standardizing numerators, denominators, and definitions is necessary.

The psychological impact of COVID-19 in a socio-politically unstable environment: protective effects of sleep and gratitude in Lebanese adults.

BACKGROUND: The COVID-19 global pandemic initiated an unprecedented medico-psychological turmoil. Our study investigates the psychological impact of the viral spread and austere lockdown, and focuses mostly on potential protective factors in a politically and economically unstable society. METHODS: A cross-sectional design was used to evaluate rates of mental distress in a sample of 348 Lebanese adults. Participants filled questionnaires of perceived stress (PSS), depression (PHQ-9), anxiety (GAD-7), PTSD (IES-22), as well as sleep (PSQi) and gratitude (GQ-6) immediately after 3 months of strict quarantine. Demographics included gender, age, employment and infection statuses. Correlations and regression models were used. RESULTS: Results indicated a very high prevalence of mental distress, in addition to major alterations in sleep quality and quantity. Younger age and unemployment correlated with more severe symptoms. Sleep was found to be a protective factor against all studied psychological distress, and gratitude further mitigated effects of depression. CONCLUSIONS: Mental health significantly degrades post-COVID lockdown, even in the absence of direct viral threat. Yet simple behavioral and cognitive changes like sleep and attitude of gratitude could provide protective factors against these psychological distresses. Such changes should be further explored and advocated as cost-efficient self-care practices to buffer this devastating public health burden, especially in unstable socio-political environments.
