Objective: To determine the prevalence of and factors associated with molar incisor hypomineralization (MIH) in schoolchildren aged 6–12 years. Study design: This study included 1156 schoolchildren aged 6–12 years, living in Mexico City. A previously standardised examiner (k = 0.79) applied the diagnostic criteria for MIH from the European Academy of Paediatric Dentistry. Children's parents completed a questionnaire about medical conditions in the perinatal period and the first 3 years of their children's lives. Descriptive measures were examined, multivariate logistic regression analysis was performed, and odds ratios (ORs) were calculated. Results: The subjects were 582 (50.4%) females and 574 (49.6%) males, with an average age of 8.4 ± 1.6 years. The prevalence of MIH was 15.8%, and this condition was more prevalent in children aged 9–12 years than in those aged 6–8 years (18% vs. 13.7%, p < 0.05). Risk factors for MIH were low birth weight (OR = 1.905, 95% confidence interval [CI] 1.130–3.211, p = 0.014), urinary tract infection (OR = 4.841, 95% CI 2.863–8.186, p = 0.001), chickenpox (OR = 1.826, 95% CI 1.196–2.786, p = 0.005), and history of allergies (OR = 4.370, 95% CI 2.538–7.523, p < 0.001). Conclusions: The prevalence of MIH in a group of Mexican schoolchildren was 15.8%. Medical conditions in the first years of life were more prevalent in children affected by MIH.

Background and Purpose: Recurrent ischemic strokes increase the risk of disability and mortality. The role of conventional risk factors in recurrent strokes may change due to increased awareness of prevention strategies. The aim of this study was to explore the potential risk factors besides conventional ones which may help to affect the advances in future preventive concepts associated with one-year stroke recurrence (OSR). Methods: We analyzed 6,632 adult patients with ischemic stroke. Differences in clinical characteristics between patients with and without OSR were analyzed using multivariate logistic regression and classification and regression tree (CART) analyses. Results: Among the study population, 525 patients (7.9%) had OSR. Multivariate logistic regression analysis revealed that male sex (OR 1.243, 95% CI 1.025 – 1.506), age (OR 1.015, 95% CI 1.007 - 1.023), and a prior history of ischemic stroke (OR 1.331, 95% CI 1.096 – 1.615) were major factors associated with OSR. CART analysis further identified age and a prior history of ischemic stroke were important factors for OSR when classified the patients into three subgroups (with risks of OSR of 8.8%, 3.8%, and 12.5% for patients aged > 57.5 years, ≤ 57.5 years/with no prior history of ischemic stroke, and ≤ 57.5 years/with a prior history of ischemic stroke, respectively). Conclusions: Male sex, age, and a prior history of ischemic stroke could increase the risk of OSR by multivariate logistic regression analysis, and CART analysis further demonstrated that patients with a younger age (≤ 57.5 years) and a prior history of ischemic stroke had the highest risk of OSR.

The yips are a set of conditions associated with intermittent motor disturbances that affect precision movement, especially in sports. Specifically, skilled golfers suffer from the yips, although its clinical characteristics and pathophysiology have not been well-studied. We surveyed skilled golfers to characterize their yips-related symptoms, to explore potential confounding factors associated with the yips. Golfers’ demographic information, golfing-career-related history, musculoskeletal status and manifestations of the yips are surveyed. Among the 1576 questionnaires distributed, 1457 (92%) responses were received, of which 39% of golfers had experienced the yips. The median age and golfing careers were 48 and 28 years, respectively. Golfers who had experienced the yips were older and had longer golfing careers and more frequent musculoskeletal problems than those without experience of the yips. The multivariate logistic regression analysis revealed that a longer golfing career and musculoskeletal problems were independent factors associated with yips experience. More severe musculoskeletal problems were associated with higher odds of experiencing the yips. A positive association between the yips and musculoskeletal problems was also observed. The yips have similar characteristics to task-specific movement disorders, with a detrimental effect caused by excessive repetition of a routine task. These findings support the notion that the yips are a type of task-specific dystonia.

UNSTRUCTURED COVID-19 has been particularly devastating to Black and Latinx communities in the U.S. However, data on acceptability of the COVID-19 vaccines among minority populations are limited. We conducted an online survey among adults in Puerto Rico to identify factors associated with intention to vaccinate against COVID-19. Sociodemographic variables were analyzed independently for association with intention to vaccinate. Significant associations were included in the multivariate logistic regression analysis. A total of 1016 responses were available for analysis. In the bivariate analysis, younger age, higher education, pre-covid employment, male sex, gay/bisexual identity, and single marital status were associated with increased intention to vaccinate. In the multivariate logistic regression, younger, male respondents who had higher educational attainment reported higher intention to vaccinate. Lower-income and living outside the San Juan metro region were associated with lower intention to vaccinate. National and international health organizations were identified as the most reliable sources of information, followed by healthcare professionals. These findings highlight the importance of considering sociodemographic characteristics identified with low intention to vaccinate as well as using trusted sources of information when designing public messaging related to increasing COVID-19 vaccinations.

Abstract Background HIV-associated non-AIDS (HANA) conditions are becoming common as People Living with Human Immunodeficiency Virus (PLWHIV) age. However, data estimating the prevalence of HANA conditions and associated risk factors is lacking in developing countries. This study evaluates reasons for hospitalizations among PLWHIV in Udupi, India in the antiretroviral era, and describes associated risk factors. Methods Demographic and clinical data were extracted from medical charts of 1280 HIV-infected patients 18 years and older who were admitted to Kasturba Hospital, Manipal, India between January 1, 2013 and December 31, 2017, for a total of 2157 hospitalizations. Primary reasons for hospitalization were categorized into AIDS-defining vs Non-AIDS-defining and HANA vs Non-HANA conditions (Fig 1). Multivariate logistic regression analysis was performed to estimate demographic and clinical factors associated with hospitalizations due to AIDS-defining illness and HANA conditions. Categorization of Reasons for Hospitalization Results Patients’ median age was 45 (18-80) years; 70% male. Median age of patients with AIDS-defining illness (45% of hospitalizations) was lower at 44 (18-75) years compared with HANA (15% of hospitalizations) at 48 (21-80) years. Age (OR, 95% CI) (0.985, 0.974-0.995), admission CD4 (0.998, 0.997 - 0.998), history of hypertension (HTN) (0.59, 0.42-0.82), stroke (0.49, 0.24 - 0.93), diabetes (1.56, 1.10 - 2.19), and AIDS-defining cancers (1.74, 1.05 - 2.89) were associated with AIDS-defining hospitalizations (Fig 2). Additionally, age (1.016, 1.001 - 1.031), history of HTN (1.70, 1.16 - 2.46), coronary artery disease (CAD) (4.02, 1.87- 9.02), chronic kidney disease (CKD) (2.30, 1.15 - 4.61), stroke (2.93, 1.46 - 5.96), Hepatitis B (3.32, 1.66- 6.72), Hepatitis C (16.1, 2.84 - 314), sexually transmitted disease (STD) (3.76, 1.38- 10.8), and HANA-associated cancer (2.44, 1.28- 6.42) were associated with HANA hospitalizations (Fig 3). Patient Risk Factors for AIDS-related Hospitalization Patient Risk Factors for HANA-related Hospitalization Conclusion Prevalence of HANA conditions was lower than AIDS-defining illnesses possibly because of a younger population. Patients with AIDS-defining illnesses were also likely to have HANA conditions. Early detection and effective treatment of both HIV and HANA conditions is essential to decrease hospitalizations in low-resource settings. Disclosures All Authors: No reported disclosures

Introduction. Bacterial infections are more frequent in patients with decompensated cirrhosis than those with compensated liver disease and account for significant morbidity and mortality in them. Once an infection develops, it induces excessive production of pro-inflammatory cytokines leading to organ failure and death. Aims. This study aims to identify the clinical characteristics and outcome of bacterial infections affecting various organ systems in patients with liver cirrhosis and to determine factors associated with mortality. Materials and methods. A cross sectional study was performed on subjects with cirrhosis having microbiologically proven bacterial infection involving various organ systems, admitted to a tertiary care hospital in southern India. Demographic, clinical data, laboratory parameters and outcome details were noted. Univariate associations and subsequent multivariate logistic regression analysis was performed to determine factors associated with mortality. Results. The study included 158 patients. Chronic alcohol intake was the most common etiology of cirrhosis (66.4%). Community acquired infections occurred more frequently than hospital acquired infections (85.5% vs 14.5%). The common site of isolation of etiological agent was ascitic fluid (38.3%) followed by blood (24.3%), respiratory tract (15.5%) and urinary tract (14.5%). Gram negative bacterial infections were more common (74.3%), Escherichia coli being the most frequent pathogen (38.5%). Mortality was noted in 38 (24%) patients. The factors associated with mortality were the type of infection, Child Pugh category, acute kidney injury, hepatic encephalopathy, urinary tract infection, and creatinine and bilirubin levels. Multivariate logistic regression analysis revealed that type of infection (OR: 0.33, 95% CI: 0.11-1.01), ascitic fluid infection (OR: 2.81, 95% CI: 1.11-7.12), hepatic encephalopathy (OR: 0.17, 95% CI: 0.070-0.422) and acute kidney injury (OR: 0.19, 95% CI: 0.077-0.502) were significantly associated with in-hospital mortality. Conclusion. This study indicates that the type of infection, hepatic encephalopathy, ascitic fluid infection and acute kidney injury are associated with mortality in cirrhotic patients. Early effective treatment and prevention of these complications may help modify the outcome.

Background/Aim. The assessment of association of depression and diabetes mellitus type 2 using the Patient Health Questionaire (PHQ-9) has not been done in Montenegro. The aim of this study was to assess the prevalence of depression in the patients with type 2 diabetes mellitus, and to identify the risk factors associated with the presence of depression. Methods. A cross-sectional study was conducted at the General Hospital in Bijelo Polje, from July to September, 2015. It included 70 patients over 35 years of age with the diagnosis of diabetes for at least six months. For the assessment of depression presence and intensity PHQ?9 was used. All variables associated with the presence of depression at a significance level of p < 0.05 were included into the final method of the multivariate logistic regression analysis. Results. Comorbidities were statistically significant more frequent among patients with depression (?2 = 5.40; p = 0.020). Duration of diabetes over five years was significantly associated with depression (?2 = 12.48; p < 0.001). Depression occurred more frequently among physically inactive subjects (?2 = 10.74; p = 0.005). The presence of diabetic polyneuropathy (?2 = 6.04; p = 0.014) and cataract (?2 = 5.351; p = 0.021) were also significantly associated with depression. A multivariate logistic regression analysis showed that the duration of diabetes over five years and presence of cataract were independently associated with depression. Conclusion. The risk factors for depression among the subjects with diabetes were disease duration more than five years and the presence of cataract. Since depression is a serious disease and can be a risk factor for many chronic diseases, the best way of prevention is its early detection and treatment.

ABSTRACT Objective: The purpose of this study was to investigate the diagnostic aspects, contributing conditions, and predictive key factors associated with ectopic eruption of maxillary second molars. Material and Methods: This retrospective study evaluated the study models, lateral cephalographs, and panoramic radiographs of 40 adult subjects (20 men, 20 women) with bilateral ectopic eruption and 40 subjects (20 men, 20 women) with normal eruption of the maxillary second molars. Studied variables were analyzed statistically by independent t-tests, univariate and multivariate logistic regression analysis, followed by receiver-operating characteristic analysis. Results: Tooth widths of bilateral lateral incisors, canines, and premolars were wider in the ectopic group, which resulted in greater arch lengths. The ANB angle and maxillary tuberosity distance (PTV-M1, PTV-M2) were smaller in the ectopic group. The long axes of the maxillary molars showed significant distal inclination in the ectopic group. The multivariate logistic regression analysis showed that three key factors—arch length, ANB angle, and PTV-M1 distance—were significantly associated with ectopic eruption of the second molars. The area under the curve (AUC) was the largest for the combination of the three key factors with an AUC greater than 0.75. PTV-M1 alone was the single factor that showed the strongest association with ectopic eruption (AUC = 0.7363). Conclusions: An increase in arch length, decrease in ANB angle, and decrease in maxillary tuberosity distance to the distal aspect of the maxillary first molar (PTV-M1) were the most predictive factors associated with ectopic eruption of maxillary second molars.

Abstract Background The clinical manifestations and factors associated with the severity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections outside of Wuhan are not clearly understood. Methods All laboratory-confirmed cases with SARS-Cov-2 infection who were hospitalized and monitored in Guangzhou Eighth People’s Hospital were recruited from January 20 to February 10. Results A total of 275 patients were included in this study. The median patient age was 49 years, and 63.6% had exposure to Wuhan. The median virus incubation period was 6 days. Fever (70.5%) and dry cough (56.0%) were the most common symptoms. A decreased albumin level was found in 51.3% of patients, lymphopenia in 33.5%, and pneumonia based on chest computed tomography in 86%. Approximately 16% of patients (n = 45) had severe disease, and there were no deaths. Compared with patients with nonsevere disease, those with severe disease were older, had a higher frequency of coexisting conditions and pneumonia, and had a shorter incubation period (all P &lt; .05). There were no differences between patients who likely contacted the virus in Wuhan and those who had no exposure to Wuhan. Multivariate logistic regression analysis indicated that older age, male sex, and decreased albumin level were independently associated with disease severity. Conclusions Most of the patients infected with SARS-CoV-2 in Guangzhou, China are not severe cases and patients with older age, male, and decreased albumin level were more likely to develop into severe ones.

The Relationship

Background: Although various modalities of hemodialysis (HD) are presumed to have different effects on insulin resistance (IR), the relationship between hemodiafiltration (HDF) and IR has not been fully evaluated. Methods: In a cross-sectional study, 82 non-diabetic HD patients were enrolled. The patients were divided into two groups according to the median homeostasis model assessment index (HOMA-IR) value of 1.685. Clinical and biochemical data were compared, and multivariate logistic regression analysis was performed to identify the independent factors associated with higher HOMA-IR. Results: The higher HOMA-IR group had increased body mass index (BMI), decreased HDL cholesterol, and lower beta-2 microglobulin reduction rate (β2-MG RR) compared to the lower HOMA-IR group. HOMA-IR was significantly correlated with β2-MG RR. In addition, HDF patients had lower HOMA-IR levels compared with low flux hemodialysis patients. On multivariate logistic regression analysis, BMI and HDF treatment were independent factors associated with higher and lower HOMA-IR, respectively. Conclusion: This study suggests that HDF treatment may reduce IR in non-diabetic HD patients.

Abstract Background Previous studies have indicated that medial meniscal subluxation (MMS) is associated with special types of medial meniscus tears (MMT) and chondral lesions. However, most of these studies lacked arthroscopic findings and did not adjust for possible confounders. The purpose of this study was to explore factors associated with MMS in patients with MMT using multivariate logistic regression analysis. Methods A retrospective analysis of 115 patients who underwent arthroscopic surgery for MMT was conducted. The medial meniscal extrusion (MME) distance was measured on a single mid-coronal magnetic resonance (MR) image, and the MMS group included patients with MME distance ≥3 mm (55 patients with 55 knees). Other patients were included as the control group (60 patients with 60 knees). Demographic and clinical data were collected as variates. A multivariate logistic regression analysis was performed to identify factors associated with MMS. Results In a univariate analysis, the Outerbridge classification (P=0.002) and the type of MMT (P<0.001) were significantly different between the MMS group and the control group. According to unadjusted and age- and body mass index (BMI)-adjusted multivariate logistic regression analysis, the type of MMT was an independent factor associated with MMS. Compared with horizontal tears, radial tears, posterior medial meniscus root tears (PMMRT) and complex tears had approximately 6-fold (adjusted OR 6.468, 95% CI 1.509–27.718, P=0.012), 10-fold (adjusted OR 10.324, 95% CI 1.719–61.989, P=0.011) and 4-fold (adjusted OR 4.458, 95% CI 1.602–12.408, P=0.004) higher associations with MMS, respectively. Conclusion The type of MMT was an independent factor associated with MMS in knees with MMT. Radial tears, PMMRT and complex tears were more likely than horizontal tears to result in MMS. The results suggest that MMT combined with MMS should be noted when managing MMT, especially radial tears, PMMRT and complex tears. Moreover, the results indicate that we must not only preserve the meniscus as much as possible but also restore its position to as close to normal as possible.
