The association between dietary patterns and cardiovascular disease risk factors in Iranian adults: a cross-sectional study

BackgroundDietary patterns are important factors associated with cardiovascular diseases (CVDs). We examined the association between dietary patterns derived from factor analysis and CVD risk factors.MethodsIn the present cross-sectional study, a total of 3,687 adults (aged 40 to 70 years) with one or more types of CVDs were enrolled as participants. A validated semi-quantitative food-frequency questionnaire was utilized to assess food intakes, and then dietary patterns were extracted by factor analysis. Fasting blood sugar (FBS), lipid profile, anthropometric indices, and blood pressure (BP) were measured. Multivariable-adjusted logistic regression analysis was employed to ascertain the odds ratio (OR) of CVD risk factors associated with posteriori dietary patterns. In this study, healthy and unhealthy dietary patterns were identified.ResultsAdherence to a healthy dietary pattern was associated with a decrease in systolic BP (SBP) (OR = 0.78; 95% confidence interval (CI): 0.62–0.99) and high-density lipoprotein cholesterol (HDL-C) levels (OR = 1.32; 95% CI: 1.06–1.64). Additionally, greater adherence to the unhealthy dietary pattern was positively associated with SBP (OR = 1.43; 95% CI: 1.13–1.80) and diastolic BP (DBP) (OR = 1.33; 95% CI: 1.01–1.76).ConclusionsWe concluded that greater adherence to an unhealthy dietary pattern was associated with an increase in SBP and DBP. On the other hand, greater adherence to a healthy dietary pattern could be effective in reducing SBP. Further investigation is recommended to validate these findings.

Difference in Risk Factor profile for Abdominal Aortic Aneurysm and Thoracic Aortic Aneurysm

Previous studies suggest partly different risk factor profiles of thoracic aortic aneurysm (TAA) and abdominal aortic aneurysm (AAA), but prospective data are scarce. The purpose of this prospective population-based case-control study was to investigate differences in risk factor profile between TAA and AAA. Participants in two prospective population-based studies, the Västerbotten Intervention Project (VIP) and the Monitoring of Trends and Determinants in Cardiovascular Disease (MONICA) study, between 1986 and 2010 underwent cardiovascular risk assessments, including blood samples, oral glucose tolerance test, blood pressure readings and a self-reported health questionnaire. All individuals who were later diagnosed with TAA or AAA were identified. Age, sex, and time-matched controls were selected from the same cohorts, aiming at four controls / case. Adjusted odds ratios for potential risk factors for later diagnosis of TAA and AAA respectively, were estimated by multivariate conditional logistic regression analyses. From total 96,196 individuals with prospectively collected data in the VIP/MONICA cohort, a total of 236 individuals with AAA (181 men and 55 women) and 935 matched controls, and 168 individuals with TAA (115 men and 53 women) and 662 controls were included. The average age at baseline examination was 57.0 ± 5.7 years for AAA cases and controls, and 52.1 ± 8.8 years for TAA cases and controls. Mean time between baseline examination and diagnosis of AAA/TAA was 12.1 and 11.7 years respectively. There was a clear difference in risk factor profile between AAA and TAA. Smoking, hypertension and coronary artery disease were significantly associated with later diagnosis of AAA with highest adjusted odds ratio for a history of smoking (OR 10.3, 95% CI 6.3-16.8). For TAA, hypertension was the only positive risk factor (OR 1.7, CI 1.1-2.7), while smoking was not associated. Diabetes was not associated with either AAA or TAA, neither was self-reported physical activity. In this prospective population-based case-control study risk factor profile differed between AAA and TAA. This suggests a partially different etiology for TAA and AAA.

Surviving venoarterial extracorporeal membrane oxygenation (VA-ECMO): The roles of severity scores and post-operative lactate clearance

BackgroundThis study investigated the association of the Survival After VA-ECMO (SAVE) score, Sequential Organ Failure Assessment (SOFA) score, and post-cannulation lactate levels with mortality among patients treated with veno-arterial extra-corporeal membrane oxygenation (VA-ECMO) for refractory cardiogenic shock (CS). MethodsWe performed a retrospective review of adult patients who underwent peripheral VA-ECMO cannulation from January 2018 to September 2022 at a quaternary care center. All-cause in-hospital mortality was assessed and compared to predicted mortality by SAVE and SOFA scores prior to cannulation, with adjusted odds ratio of risk factors for mortality identified by multivariate logistic regression analysis. Additionally, the prognostic value of 8-h post-cannulation serum lactate levels was analyzed by receiver operating characteristic (ROC) curve and Kaplan Meier analysis of 30-day survival. Results244 patients were included in final analysis. All-cause in-hospital mortality was 70 %, and 54 % of patients died while on ECMO or within 24 h of decannulation. Pre-cannulation SAVE score (OR 0.93 per unit increase, 95 % CI 0.86–0.99, p = 0.008), SOFA score (OR 1.54 per unit increase, 95 % CI 1.32–1.75), and 8-h post-cannulation lactate levels (OR 1.20 per mmol/L increase, 95 % CI 1.04–1.36, p = 0.008) were independently associated with all-cause in-hospital mortality.8-h post-cannulation lactate levels ≥5.3 mmol/L demonstrated high specificity for in-hospital mortality (90.0 %), while levels ≥7.8 mmol/L were demonstrated high specificity for VA-ECMO death (91.1 %). These thresholds were significantly associated with 30-day all-cause mortality (p < 0.001). ConclusionPre-cannulation SAVE and SOFA scores are useful prognostic tools in patients with CS. 8-h post-cannulation serum lactate levels are a pragmatic biomarker and can further assist in prognostication of patients on VA-ECMO, and the cutoffs of 5.3 mmol/L and 7.8 mmol/L have high specificity for all-cause mortality and VA-ECMO mortality, respectively. The development of accurate prognostic tools is critical in managing and optimizing care for patients with CS.

Risk factors and associations with atopic diseases in the pediatric population in Qatar.

Asthma is a common noncommunicable disease with public health implications due to the rising number of cases among the pediatric population in Qatar. The objective of the current study is to explore possible risk factors and associations in relation to pediatric asthma, allergic rhinitis, and eczema cases in Qatar. Using the Global Asthma Network questionnaires, this study sampled 2646 children, of which 1210 were aged 6-7 years and 1436 were aged 13-14 years in addition to 3831 adult parents or guardians. The STROBE guidelines were used to ensure the reporting of this cross-sectional study. Univariate and multivariate logistic regression were used to produce the odds ratio for the various risk factors and associated factors, respectively. Multiple associations and risk factors for each of the three diseases were reported. Based on the outcome of a multivariate logistic regression, being born in Qatar was the only risk factor present across all three diseases. Being male, wheezing ever, wheezing after exercise, and having eczema were other risk factors reported for asthma. Being in the older age group, wheezing ever, and having hay fever were other risk factors reported for allergic rhinitis. The study concluded that further evaluation into associated and risk factors for asthma, allergic rhinitis, and eczema is warranted in the future.

Risk Factors for Inadequate Bowel Preparation in Colonoscopy: A Comprehensive Systematic Review and Meta-Analysis.

Inadequate bowel preparation (IBP) before colonoscopy remains a common problem. This meta-analysis aimed to assess the risk factors associated with IBP. We searched multiple databases for studies that assessed risk factors for IBP after adjustment and reported the data as adjusted odds ratios with 95% confidence intervals. Meta-analyses were conducted using a random-effects model, and pooled adjusted odds ratios for risk factors reported in ≥ 3 studies were constructed. One hundred fifty-four studies with 358,257 participants were included. We analyzed 48 unique risk factors. Sociodemographic predictors of IBP were Medicaid insurance, obesity, current tobacco use, age ≥ 65 years, Black race, low education level, male sex, and unmarried status. Comorbidity-related predictors of IBP were any psychiatric disease, cirrhosis, American Society of Anesthesiologists (ASA) class ≥ 3, poor functional status, constipation, diabetes, previous abdominopelvic surgery, and hematochezia. Medication-related predictors of IBP were tricyclic antidepressants, antidepressants, opioids, nontricyclic antidepressants, and calcium channel blockers. Preparation/procedure-related predictors of IBP were brown liquid rectal effluent, any incomplete bowel preparation (BP) intake, lack of split-dose BP, increased BP-to-defecation interval, any nonadherence to dietary instructions, increased BP-to-colonoscopy interval, any BP intolerance, previous IBP, and inpatient status. Although afternoon colonoscopy was a predictor of IBP, subgroup analysis of prospective studies revealed no significant association. Our meta-analysis focused on adjusted risk factors to provide precise estimates of the most important risk factors for IBP. Our findings could help develop a validated prediction model to identify high-risk patients for IBP, improve colonoscopy outcomes, reduce the need for repeat colonoscopies, and reduce associated healthcare costs.

Prevalence of and risk factors for infectious disease syndromic symptoms among pilgrimage to Arba'een mass gathering religious in 2023

BackgroundThere is a growing participation of Shia Muslims, in the Arba'een pilgrimage every year. It is imperative to conduct a comprehensive study on the transmission of diseases among Arba'een pilgrims in order to identify and promptly respond to potential epidemics effectively. We aimed to assess the syndromic symptoms associated with infectious diseases and the prevalence of mask usage among patients visiting outpatient clinics during the Arba'een pilgrimage in Ira, in 2023. MethodsIn this descriptive-analytical study, 300 outpatients who sought medical care at outpatient clinics during the Arba'een pilgrimage were randomly selected. The study data and infectious disease syndromic symptoms were assessed using trained healthcare professionals. A multiple logistic regression analysis was carried out to estimate the crude and Adjusted odds ratios (AORs) of symptoms and risk factors associated with respiratory syndrome and flu-like symptoms with 95 % confidence intervals. ResultsThe mean age of the participants was 39 years and 61 % of those were male. Out of 72 (24 %) of mask users, 41.6 % had changed masks in less than 8 h. The most common syndromic symptoms was Flu-like illness (53 %). In the final analysis, not wearing a mask AOR = 1.40 (1.1–9.8) and smoking AOR = 3.25 (1.1–9.5) both elevated the risk of the flu-like syndrome and severe respiratory disease symptoms. ConclusionsPilgrims are especially vulnerable to the flu and other respiratory illnesses. Therefore, performing a differential diagnosis in these people, including flu and COVID-19, is essential to prevent an outbreak during the Arba'een pilgrimage.

A Population-Based Epidemiologic Study of Symptomatic SARS-CoV-2 Infections and Fatalities in Brazilian Children over 3 Years

To provide a comprehensive overview of the epidemiologic characteristics, outcomes, and risk factors of COVID-19-related deaths in children and adolescents in Brazil. We conducted a population-based, retrospective cohort study that included all patients aged <18years with laboratory-confirmed, symptomatic SARS-CoV-2 infection as registered in official Brazilian national surveillance systems for COVID-19 between February 2020 and February 2023. The primary outcome was COVID-19-related deaths. Odds ratios (ORs) of risk factors associated with death were estimated using multivariable logistic regression. Over a 3-year period, 2855704 pediatric patients with symptomatic SARS-CoV-2 infection were registered in Brazil. Of these, 59179 (2.1%) were hospitalized, 13844 (0.48%) were admitted to the intensive care unit, and 4943 (0.17%) received mechanical ventilation. A total of 4740 (0.17%) patients had fatal outcomes. The case fatality rate increased to 7.9% among patients who required hospitalization; 2102 (44.3%) patients who died did not receive advanced critical support. Notably, 2 (65%, 95% CI 58-71) or 3 doses (86%, 95% CI 81-89) of the vaccine provided strong protection against death. The following adjusted covariates were significantly associated with increased odds of death: age (0-4 and 11-17years), ethnicity (Brown and Indigenous), region (Northeast or North), dyspnea, nosocomial infection, and comorbidities. Conversely, living in the South or Central-West regions, admission in the later period of the pandemic, and receiving a vaccine were all associated with protection against death. Our findings suggest that a complex interplay between individual factors and social inequities has shaped the impact of COVID-19 on Brazilian children and adolescents.

Risk factors for Non-Hodgkin's lymphoma in autoimmune disease: a large database analysis.

Immune dysregulation in autoimmune diseases (ADs) is a risk factor for the development of Non-Hodgkin's lymphoma (NHL). However, the underlying mechanisms are not well understood. Hence, this retrospective study aims to describe the clinical and demographic factors that increase the risk of NHL development in patients with ADs. Our study utilised data from National Inpatient Sample (NIS) for the duration of 2016-2020 on all adult patients aged > 18 years who had NHL. We divided them into two cohorts: one with underlying ADs and one without underlying ADs. We then compared the adjusted odds ratios (aOR) of various risk factors. It was found that 0.9% of autoimmune cases had NHL, while 0.7% of non-autoimmune cases had NHL. Among those with autoimmune conditions, various factors influenced the presence of lymphoma, such as personal history of chemotherapy or radiation, family history of lymphoid malignancy, HIV infection, advanced age of 60-69 years, Asian and Pacific Islander ethnicity and viral hepatitis. The increased risk of NHL with autoimmune conditions is well established. Studies have also shown that these patients can overall have a poor prognosis from their NHL when compared to patients without autoimmune diseases. However, there is limited literature regarding the interplay of traditional NHL risk factors with underlying autoimmunity. Hence, our study sheds light on the lesser studied risk factors, such as patient characteristics and comorbidities.

The estimated 10-year risk of first-onset cardiovascular disease in Swedish-born and non-Swedish-born primary healthcare patients

BackgroundSCORE2 has been introduced as an updated risk assessment tool for calculating the 10-year risk of first-onset cardiovascular disease (CVD). However, it does not account for ethnicity or socioeconomic status, known to affect CVD risk. This study investigated and compared SCORE2 estimates in Swedish-born and non-Swedish-born primary healthcare patients. The second aim was to examine if several risk factors could explain differences in CVD risk between the groups.MethodsThis was an observational, cross-sectional study. Data were obtained from the 4D Diabetes Project study, providing a total of 444 participants aged between 40 and 69 years. All participants had complete risk variable data necessary for the SCORE2 tool and no history of previous CVD. Descriptive analysis was conducted to compare distributions of risk factors between Swedes and immigrants and odds ratios of risk factors amongst these two groups in correlation to elevated CVD risk were calculated using logistic regression.ResultsSwedish-born patients showed a significantly higher risk of elevated CVD risk estimates (≥ 2.5% CVD risk increase for individuals < 50 years, respectively, ≥ 5% for individuals aged 51–69) than the non-Swedish-born population, even after adjustment for educational level (OR = 1.61, 95% CI 1.08–2.39). Weekly alcohol consumption implicated a risk of being classified as high risk of CVD risk, regardless of country of birth (OR = 1.93 CI 1.25-3.00). However, Swedes accounted for most of the alcohol consumption (62.6% vs. 19.6%). No other explanatory variable showed significance in association with elevated CVD risk.ConclusionsSwedish-born patients were found to be at higher risk of an increased 10-year CVD risk. The association of alcohol consumption with elevated CVD risk needs to be further studied in longitudinal studies in representative populations, notably among Sweden’s diverse ethnic groups.

The UF-5000 Atyp.C parameter is an independent risk factor for bladder cancer

Bladder carcinoma (BC) accounts for > 90% of all urothelial cancers. Pathological diagnosis through cytoscopic biopsy is the gold standard, whereas non-invasive diagnostic tools remain lacking. The “Atyp.C” parameter of the Sysmex UF-5000 urine particle analyzer represents the ratio of nucleus to cytoplasm and can be employed to detect urinary atypical cells. The present study examined the association between urinary Atyp.C values and BC risk. This two-center, retrospective case–control study identified clinical primary or newly recurrent BC (study period, 2022–2023; n = 473) cases together with controls with urinary tract infection randomly matched by age and sex (1:1). Urinary sediment differences were compared using non-parametric tests. The correlations between urinary Atyp.C levels and BC grade or infiltration were analyzed using Spearman’s rank correlation. The BC risk factor odds ratio of Atyp.C was calculated using conditional logistic regression, and potential confounder effects were adjusted using stepwise logistic regression (LR). Primary risk factors were identified by stratified analysis according to pathological histological diagnosis. The mean value of urinary Atyp.C in BC cases (1.30 ± 3.12) was 8.7 times higher than that in the controls (0.15 ± 0.68; P < 0.001). Urinary Atyp.C values were positively correlated with BC pathological grade and invasion (r = 0.360, P < 0.001; r = 0.367, P < 0.001). Urinary Atyp.C was an independent risk factor for BC and closely related with BC pathological grade and invasion. Elevated urinary Atyp.C values was an independent risk factor for BC. Our findings support the use of Atyp.C as a marker that will potentially aid in the early diagnosis and long-term surveillance of new and recurrent BC cases.

The seroprevalence of antibodies to Japanese encephalitis virus in five New South Wales towns at high risk of infection, 2022: a cross-sectional serosurvey.

To determine the proportion of people in New South Wales towns at high risk of Japanese encephalitis virus (JEV) infections during the 2022 outbreak; to identify risk factors for JEV infection. Cross-sectional serosurvey study of the seroprevalence of JEV-specific antibodies in NSW. Convenience sample of people (all ages) from five regional NSW towns deemed to be at high risk of JEV infections after first outbreak of Japanese encephalitis in southeastern Australia in early 2022 (Balranald, Corowa, Dubbo, Griffith, Temora), 21 June - 22 July 2022. Proportion of people seropositive for JEV total antibody, assayed by defined epitope-blocking enzyme-linked immunosorbent assay; prevalence odds ratios for exposure risk factors and protective behaviours. Eighty of 917 eligible participants (559 girls or women, 61%; 42 Aboriginal and Torres Strait Islander people, 4.6%; median age, 52 years [IQR, 37-62 years]) were seropositive for JEV-specific total antibody (8.7%); the median age of seropositive people was 61 years (IQR, 48-70 years). The seropositivity proportion was largest for people aged 65 years or more (30 of 192; weighted proportion, 13.7%) and larger for male than female participants (30 of 358, 10.6% v 50 of 559, 7.5%). Five of 42 samples from Aboriginal and Torres Strait Islander participants were seropositive (12%). We found mixed associations with a range of potential risk factors. We found evidence for a substantial number of JEV infections in five regional NSW towns during a single arbovirus season in 2022. Public health responses, including effective surveillance, vaccination against JEV, and mosquito management, are critical for controlling outbreaks. Promoting behaviours that reduce exposure to mosquitoes is a core component of prevention, particularly when the vaccine supply is limited.

ASSESSING RISK FACTORS FOR OSTEOPOROSIS AND FRACTURES AT DIFFERENT SITES: LUMBAR VERTEBRAE VERSUS NECK OF FEMURS IN A LARGE COHORT. A CROSS-SECTIONAL STUDY

Osteoporosis can cause significant disability and cost to health services globally. We aim to compare risk fractures for both osteoporosis and fractures at the L1-L4 vertebrae (LV) and the neck of femurs (NOFs) in patients referred for DEXA scan in the North-West of England.Data was obtained from 31546 patients referred for DEXA scan in the North-West of England between 2004 and 2011. Demographic data was retrospectively analysed using STATA, utilising chi-squared and t-tests. Logistical models were used to report odds ratios for risk factors included in the FRAX tool looking for differences between osteoporosis and fracture risk at the LV and NOFs.In a study involving 2530 cases of LV fractures and 1363 of NOF fractures, age was significantly linked to fractures and osteoporosis at both sites, with a higher risk of osteoporosis at NOFs compared to LV. Height provided protection against fractures and osteoporosis at both sites, with a more pronounced protective effect against osteoporosis at NOFs. Weight was more protective for NOF fractures, while smoking increased osteoporosis risk with no site-specific difference. Steroids were unexpectedly protective for fractures at both sites, with no significant difference, while alcohol consumption was protective against osteoporosis at both sites and associated with increased LV fracture risk. Rheumatoid arthritis increased osteoporosis risk in NOFs and implied a higher fracture risk, though not statistically significant compared to LV. Results summarised in Table 1.Our study reveals that established osteoporosis and fracture risk factors impact distinct bony sites differently. Age and rheumatoid arthritis increase osteoporosis risk more at NOFs than LV, while height and steroids provide greater protection at NOFs. Height significantly protects LV fractures, with alcohol predicting them. Further research is needed to explore risk factors’ impact on additional bony sites and understand the observed differences’ pathophysiology.For any figures or tables, please contact the authors directly.

Risk prediction of advanced colorectal neoplasia among diabetic patients: A derivation and validation study.

Colorectal cancer (CRC) is the third most common cancer in the world. This study devises and validates a clinical scoring system for risk prediction of advanced colorectal neoplasia (ACN) to guide colonoscopy evaluation among diabetic patients. We identified 55 964 diabetic patients who received colonoscopies from a large database in a Chinese population (2008-2018). We recruited a derivation cohort based on random sampling. The risk factors of CRC evaluated by univariate analysis were examined for ACN, defined as advanced adenoma, CRC, or any combination thereof using binary logistic regression analysis. We used the adjusted odds ratios (aORs) for independent risk factors to devise a risk score, ranging from 0 to 6: 0-4 "average risk" (AR) and 5-6 "high risk" (HR). The other subjects acted as an independent validation cohort. The prevalence of ACN in both the derivation and validation cohorts was 2.0%. Using the scoring system constructed, 78.5% and 21.5% of patients in the validation cohort were classified as AR and HR, respectively. The prevalence of ACN in the AR and HR groups was 1.5% and 4.1%, respectively. Individuals in the HR group had a 2.78-fold increased prevalence of ACN than the AR group. The concordance (c-) statistics was 0.70, implying a good discriminatory capability of the risk score to stratify high-risk individuals who should consider colonoscopy. The clinical risk scoring system based on age, gender, smoking, presence of hypertension, and use of aspirin is useful for ACN risk prediction among diabetic patients.

Determinants of diabetic nephropathy among diabetic patients in Ethiopia: Systematic review and meta-analysis.

Diabetic nephropathy (DN) is a long-term kidney disease among diabetic patients. It is the leading cause of end-stage renal failure. In Ethiopia, DN affects the majority of diabetic populations, but there were inconsistent findings about the determinant factors across the studies. We have accessed studies using PubMed, Embase, EBSCO, Web of Science, OVID, and search engines including Google and Google Scholar published up to June 2023. The study populations were diabetic patients with nephropathy. The quality of each included article was assessed using the Newcastle-Ottawa quality assessment scale. The odds ratios of risk factors were pooled using a random-effect meta-analysis model. Heterogeneity was assessed using the Cochrane Q statistics and I-Square (I2). The publication bias was detected using the funnel plot and/or Egger's test (p< 0.05). Trim and fill analysis was carried out to treat the publication bias. The protocol has been registered with the reference number CRD42023434547. A total of sixteen articles were used for this reviewed study. Of which, eleven articles were used for advanced age, ten articles for duration of diabetic illness, ten articles for poor glycemic control, and eleven articles for having co-morbid hypertension. Diabetic patients with advanced age (AOR = 1.11, 95% CI: 1.03-120, I2 = 0.0%, p = 0.488), longer duration of diabetic illness (AOR = 1.23, 95% CI = 1.05-1.45, I2 = 0.0%, p = 0.567), poor glycemic control (AOR = 2.57, 95% CI: 1.07-6.14; I2 = 0.0%, p = 0.996), and having co-morbid hypertension (AOR = 4.03, 95% CI: 2.00-8.12, I2 = 0.0%, p = 0.964) were found to be factors associated with DN. The findings of the study revealed that diabetic patients with advanced age, longer duration of diabetic illness, poor glycemic control status, and co-morbid hypertension were the determinant factors of DN. Therefore, treatment of co-morbid hypertension and high blood glucose and regular screening of renal function should be implemented to detect, treat, and reduce the progression of DN. Furthermore, healthcare workers should give due attention to diabetes with advanced age and a longer duration of diabetes illness to prevent the occurrence of DN.

Systematic review and meta-analysis of the clinical features of MGRS

BackgroundIt is crucial to identify patients with monoclonal gammopathy of renal significance (MGRS) from those without MGRS but with monoclonal gammopathy and concomitant kidney diseases. However, there have been few studies with large sample sizes, and their findings were inconsistent. This study aimed to conduct a meta-analysis of MGRS to describe the general characteristics of MGRS and its predictive factors.MethodsCohort or case-control studies published through December 2022 and related to clinicopathological features of MGRS were retrieved from the PubMed, Cochrane Library, Web of Science, Scopus, and Embase databases. Two researchers searched for studies that met the inclusion criteria. In the univariate analysis, fixed- or random- effects models were used to obtain pooled estimates of the weighted mean difference (WMD) and odds ratio (OR) for risk factors. In the multivariate analysis, the ORs of the independent risk factors from each study were pooled after transforming the original estimates.ResultsThe meta-analysis included six studies. Univariate analysis showed that the following variables were statistically significant in MGRS: age (WMD = 1.78, 95%CI 0.21–3.35), hypertension (OR = 0.54, 95%CI 0.4–0.73), diabetes (OR = 0.42, 95%CI 0.29–0.59), albumin (WMD = − 0.26, 95%CI − 0.38–−0.14), urinary protein level (WMD = 0.76, 95%CI 0.31–1.2), urinary protein ≥ 1.5 g/d (OR = 1.98, 95%CI 1.46–2.68), lambda-chain value (WMD = 29.02, 95%CI 16.55–41.49), abnormal free light-chain ratio (OR = 4.16, 95%CI 1.65–10.47), bone marrow puncture rate (OR = 5.11, 95% CI 1.31–19.95), and abnormal bone marrow outcome rate (OR = 9.63, 95%CI 1.98–46.88). Multivariate analysis showed urinary protein ≥ 1.5 g/d (OR = 2.80, 95%CI 1.53–5.15) and an abnormal free light-chain ratio (OR = 6.98, 95%CI 4.10–11.91) were associated with predictors of MGRS.ConclusionsCompared with non-MGRS patients with monoclonal gammopathy and concomitant kidney diseases, patients with MGRS were older, had fewer underlying diseases, more urinary protein, more abnormal free light-chain ratio, and more abnormal bone marrow results. Urinary protein ≥ 1.5 g/d and an abnormal free light-chain ratio were independent risk factors for MGRS.

Prevalence, clinical presentation, and risk factors of chronic venous disease in Cameroon: A general population-based study.

Chronic venous disease is a global public health problem, with high morbidity and economic distress. There is scarcity of data on this disease in sub-Saharan Africa. We conducted the first population-based study over a period of 20months from 1st February 2020 to 30th September 2021 in the 10 regions of Cameroon. A stratify sampling method was chose to select study site. Socio-demographic data, personal and family history, anthropometric parameters, clinical signs, illustrative images, CEAP (Clinical-Etiological-Anatomical-Pathophysiological) classification revised in 2004, VCSS (venous Clinical Severity Score) and risk factor assessment score were used to construct the survey form. Chi-squared test and Fischer exact test were used to compare the prevalence of chronic venous disease across different potential risk factors (sex, age category, previous history of deep vein thrombosis, hypertension, diabetes, smoking status, obesity). Simple and multiple logistic regression models were used to obtain crude and adjusted odds ratio for risk factors associated with chronic venous insufficiency. Statistical analyses were done with R version 4.2 for Linux and the threshold for statistical significance was 0.05. A total of 6578 participants were included in the study, with a mean age of 41.09 ± 16.02years with female predominance (54.3%). The prevalence of chronic venous disease was 21.8% (95% CI: 20.8-22.9) and the prevalence of chronic venous insufficiency (C3-C6) was 7.02% (n = 462). Night cramps (43.2%), oedema (21.7%), lower limbs pain (20.4%) mostly worsens by walking and heavy legs (16.2%) were more common symptoms. The mean total venous clinical severity score was 0.69 ± 1.76 and this score had a significant positive correlation with C classification (p < .001). In the multivariate analysis, the following factors were independently associated with CVD: Male gender (aOR: 1.27; 95%CI: 1.04-1.56; p = .021), retired people (aOR: 46.9; 95% CI: 12.6-174.5; p < .001), hypertension (aOR: 289.5; 95%CI: 169.69-493.1; p < .001), diabetes (aOR: 2.19; 95% CI: 1.21-3.96; p = .009), obesity (aOR: 10.22; 95%CI: 7.67-13.62; p < .001). Smoking appears as a protective factor (aOR: 0.18; 95%CI: 0.10-0.30; p < .001). Chronic venous disease is frequent in Cameroon and main traditional cardiovascular risk factors are associated to this condition. Systematic screening of the CVD in these specific groups could reduce the burden of the disease and its economic impact.

Elevated triglycerides and low triiodothyronine: Key risk factors for coronary artery calcification in patients with schizophrenia

ObjectiveCoronary artery calcification (CAC) is a well-established independent predictor of coronary heart disease, and patients with schizophrenia have significantly higher rates compared to the general population. We performed this study to examine the population-specific risk factors associated with CAC in patients with schizophrenia. MethodsIn this cross-sectional study, patients with schizophrenia who underwent low-dose chest CT scans between January 2020 and December 2021 were analyzed. Ordinary CAC scores and results of routine blood tests were obtained. Logistic regression was used to calculate the odds ratio (OR) for potential risk factors in patients with and without CAC, while the negative binomial additive model was used to explore the dose-response relationship between risk factors and CAC score. ResultsOf the 916 patients, 233 (25.4 %) had CAC, while 683 (74.6 %) did not. After adjusting for confounding factors, higher triglyceride levels (OR = 1.20, 95 % confidence interval (CI): 1.04 to 1.38, p = 0.013) and low triiodothyronine levels (OR = 0.50, 95 % CI: 0.29 to 0.84; p = 0.010) were identified as risk factors for CAC. Both triglycerides (p = 0.021) and triiodothyronine (p = 0.010) were also found to have significant dose-response relationships with CAC scores according to the negative binomial additive model in the exploratory analysis. ConclusionsThis study highlights elevated serum triglycerides and decreased triiodothyronine levels as population-specific risk factors for CAC in patients with schizophrenia, suggest the need for close monitoring of CAC in patients with schizophrenia and further prospective trials to provide additional evidence on this topic.

The Global and Regional Prevalence of Hospital-Acquired Carbapenem-Resistant Klebsiella pneumoniae Infection: A Systematic Review and Meta-analysis.

Due to scarce therapeutic options, hospital-acquired infections caused by Klebsiella pneumoniae (KP), particularly carbapenem-resistant KP (CRKP), pose enormous threat to patients' health worldwide. This study aimed to characterize the epidemiology and risk factors of CRKP among nosocomial KP infections. MEDLINE, Embase, PubMed, and Google Scholar were searched for studies reporting CRKP prevalence from inception to 30 March 2023. Data from eligible publications were extracted and subjected to meta-analysis to obtain global, regional, and country-specific estimates. To determine the cause of heterogeneity among the selected studies, prespecified subgroup analyses and meta-regression were also performed. Odds ratios of CRKP-associated risk factors were pooled by a DerSimonian and Laird random-effects method. We retained 61 articles across 14 countries and territories. The global prevalence of CRKP among patients with KP infections was 28.69% (95% CI, 26.53%-30.86%). South Asia had the highest CRKP prevalence at 66.04% (95% CI, 54.22%-77.85%), while high-income North America had the lowest prevalence at 14.29% (95% CI, 6.50%-22.0%). In the country/territory level, Greece had the highest prevalence at 70.61% (95% CI, 56.77%-84.45%), followed by India at 67.62% (95% CI, 53.74%-81.79%) and Taiwan at 67.54% (95% CI, 58.65%-76.14%). Hospital-acquired CRKP infections were associated with the following factors: hematologic malignancies, corticosteroid therapies, intensive care unit stays, mechanical ventilations, central venous catheter implantations, previous hospitalization, and antibiotic-related exposures (antifungals, carbapenems, quinolones, and cephalosporins). Study findings highlight the importance of routine surveillance to control carbapenem resistance and suggest that patients with nosocomial KP infection have a very high prevalence of CRKP.

Risk Factors for Non-Hodgkin's Lymphoma in Autoimmune Diseases: A Large Database Analysis

Introduction It has been well studied that immune dysregulation in autoimmune diseases is a risk factor for the development of Non-Hodgkin's lymphoma (NHL). However, the underlying mechanisms are not well understood. Although certain traditional risk factors like prolonged immunosuppression, infections, advanced age, family history, and history of organ transplantation are well described in NHL patients, there is limited literature regarding their interplay with autoimmune diseases. Hence, we conducted this retrospective study from the National inpatient sample database to describe the various clinical and demographic factors that increase the risk of NHL development in patients with autoimmune diseases. Methods Our study was conducted using the National Inpatient Sample, which is a large all-payer inpatient care database in the United States. We collected data from 2016-2020 on all adult patients aged &amp;gt; 18 years who had NHL. We divided them into two cohorts: one with underlying autoimmune diseases and one without underlying autoimmune conditions. We then compared the adjusted odds ratios (aOR) of various risk factors like age, race, gender, obesity, family history of lymphoproliferative diseases, personal history of chemotherapy or radiation, history of HIV, HTLV-1, Helicobacter pylori infection, Chlamydia infection, history of solid organ transplantation, and long-term steroid use among the two cohorts. Results Our data initially consisted of 148,755,036 patients ages ≥18 years, with 4,291,559 cases having autoimmune disorders like rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), Systemic sclerosis, sarcoidosis, sjogren's syndrome, and celiac disease. We found that 0.9% of autoimmune cases had NHL, while 0.7% of non-autoimmune cases had NHL (aOR 1.272, 95% CI 1.258-1.285, p&amp;lt;0.01). Among those with autoimmune conditions, various factors also influenced the presence of lymphoma, such as personal history of chemotherapy or radiation (aOR 5.778, 95% CI 5.595- 5.9675, p &amp;lt;0.001), family history of lymphoid malignancy (aOR 5.316, 95% CI 4.666-6.058, p&amp;lt;0.001), HIV infection (aOR 1.944, 95% CI 1.674-2.257,p&amp;lt;0.001), advanced age of 60-69 years (aOR 1.051, 95% CI 1.025-1.078, p&amp;lt;0.001) , Asian and Pacific Islander ethnicity (aOR 1.596, 95%CI 1.496-1.703, p&amp;lt;0.001) and viral hepatitis (aOR 1.620, 95% CI 1.480-1.774, p&amp;lt;0.001) (Table 1). Conclusion The increased risk of non-Hodgkin Lymphoma (NHL) with autoimmune conditions like rheumatoid arthritis and SLE is well established. Studies have also shown that these patients can overall have a poor prognosis from their NHL when compared to patients without autoimmune diseases. However, there is limited literature regarding the interplay of traditional NHL risk factors with underlying autoimmunity. Hence, our retrospective analysis sheds light on the lesser studied risk factors, such as patient characteristics and comorbidities. We found that older age, male sex, Asian and Pacific Islander race, family history of lymphoid malignancy, personal history of chemotherapy or radiation, and comorbidities like HIV, Viral Hepatitis, and HTLV-1 are some strong risk factors associated with the development of NHL in patients with autoimmune diseases. Infections like HIV and HTLV-1 played less of a role in the autoimmune cohort as opposed to the non-autoimmune cohort. Whereas personal histories of chemotherapy and radiation and family histories of lymphoid malignancies were demonstrated to be very strong risk factors in both settings. Hence, our study enables clinicians to identify the differences in the interplay of these risk factors and to perform stringent monitoring of patients when they do have these risk factors

Impact of Race/Ethnicity and Insurance Status on Obstetric Outcomes: Secondary Analysis of the NuMoM2b Study.

This study aimed to investigate the impact of race/ethnicity and insurance status on obstetric outcomes in nulliparous women. Secondary analysis of the Nulliparous Pregnancy Outcomes Study Monitoring Mothers-To-Be. Obstetric outcomes included the development of a hypertensive event during pregnancy, need for a cesarean section, delivery of a preterm neonate, and postpartum hemorrhage. Of 7,887 nulliparous women, 64.7% were non-Hispanic White (White), 13.4% non-Hispanic Black (Black), 17.8% Hispanic, and 4.1% were Asian. Black women had the highest rates of developing new-onset hypertension (32%) and delivering preterm (11%). Cesarean deliveries were the highest in Asian (32%) and Black women (32%). Individuals with government insurance were more likely to deliver preterm (11%) and/or experience hemorrhage after delivery. In multivariable analyses, race/ethnicity was associated with hypertension and cesarean delivery. More important, the adjusted odds ratios for preventable risk factors, such as obesity, diabetes, and severe anemia were greater than the adjusted odds ratios for race/ethnicity in terms of poor maternal outcome. Although disparities were observed between race/ethnicity and obstetric outcomes, other modifiable risk factors played a larger role in clinical differences. · Race or insurance alone had mixed associations with maternal morbidities.. · Race and insurance had low associations with maternal morbidities.. · Other, modifiable risk factors may be more important.. · Both social and biological factors impact health disparities..
