Corneal Endothelial Cells and Central Corneal Thickness in Pseudoexfoliation Patients

Objective: Investigating the impact of pseudoexfoliation syndrome on changes occurring in corneal endothelial cells and central corneal thickness, while assessing the influence of the degree of pseudoexfoliation on endothelial cell changes. Methods: In this analytic case-control study (Cross Sectional), the research sample included 60 patients (120 eyes) from the ophthalmic clinic attendees at Tishreen University Hospital in Latakia during the period 2023-2024. Results: The average corneal endothelial cell count was lower in the pseudoexfoliation group (2218.91±311.5 cells/mm²) compared to the control group (2559.82±290.7 cells/mm²) with a (p-value of 0.0001). The average percentage of hexagonal cells was lower in the pseudoexfoliation group (48.55±14.9 %) compared to the control group (62.32±9.7%) with a (p-value of 0.0001). No statistically significant differences were observed between the research groups in terms of average cell volume change coefficient with a (p-value of 0.9). The average cell area was higher in the pseudoexfoliation group (487.92±71.3 µm²) compared to the control group (419.94±72.2 µm²) with a (p-value of 0.003). The average central corneal thickness was lower in the pseudoexfoliation group (515.93±41.9 µm) compared to the control group (544.22±26.6 µm) with a (p-value of 0.04). We observed increased changes in corneal endothelial cells and central corneal thickness with an increase in the degree of pseudoexfoliation. Conclusion: Corneal endothelial cells and central corneal thickness are affected in patients with pseudoexfoliation syndrome, and these changes increase with severity of pseudoexfoliation.

No association between history of psychiatric treatment and postoperative weight reduction after bariatric surgery

PurposeThe objective of the study was to assess whether the history of psychiatric treatment was associated with (1) body weight and BMI on admission for bariatric surgery, (2) weight loss > 5 kg prior to bariatric surgery, and (3) postoperative body weight reduction.MethodsData from medical records of all consecutive patients admitted for surgical treatment of obesity in the 2nd Department of General Surgery Jagiellonian University Medical College were obtained. There were 1452 records of patients who underwent bariatric surgery between 2009 and 2021 included in the study.ResultsHistory of psychiatric treatment was found in 177 (12%) of the sample and was inversely associated with body weight and BMI on admission for surgery in women. Men with history of psychiatric treatment were 54% less likely to lose > 5 kg before the surgery (OR = 0.46 95% CI = 0.24–0.88). Both in men and women %TWL did not differ significantly by history of psychiatric treatment (Me: 40.7 vs. 45.9; p = 0.130 and Me: 27.0 vs. 23.9; p = 0.383, respectively). After adjustment for covariates no association was found between history of psychiatric treatment and body weight reduction one year after surgery.ConclusionAlthough men with preoperative history of psychiatric treatment had lower odds of losing weight before the surgery, psychiatric treatment did not differentiate the effectiveness of bariatric treatment in 1 year of observation. Bariatric surgery appears to be an effective obesity care for people treated for mental disorders.Level of evidence: III Evidence obtained from cohort or case-control analytic studies.

Sexual dysfunction, marital relationship, and subjective quality of life among women with schizophrenia: Analytical case-control study

Background: Women with schizophrenia have a high risk of adverse sexual health outcomes. The chronic course of schizophrenia draws attention to assessing the quality of life and marital relationships of patients with schizophrenia. However, there is a crunch of data in the Indian setting. This study aimed to investigate the prevalence of sexual dysfunctions (SDs) and determine the marital relationship and quality of life among women with schizophrenia. Material and Methods: The study followed an analytical case-control design. The study was conducted at the inpatient psychiatric department of one of the apex tertiary healthcare centers located at the foothills of the Northern Himalayas. The study purposively included 136 participants (68 cases and 68 controls). The control group included healthy women aged 18–45 currently staying with sexual partners. Data were collected using pretested and standardized self-report questionnaires. Results: The median age of the case group was 36 (interquartile range (IQR), 29–42) years, while that of the control group was 29 (IQR 26–34) years. The prevalence of SD was significantly higher (P = 0.001) in cases (95.3%) than in controls (73.4%). Compared to healthy controls, women with schizophrenia have a significantly higher rate of SD in sexual desire (P = 0.001), getting arousal (P < 0.001), lubrication (P < 0.001), achieving orgasm (P < 0.001), and sexual satisfaction (P < 0.001) (except pain). In addition, the marital relationship was better managed (P < 0.001) in healthy controls compared with cases. The healthy control group significantly expressed a better quality of life in physical (P < 0.001), psychological (P < 0.001), and maintaining social (P < 0.001) relationships (except environment domains). In multivariable logistic regression analysis, employment status significantly predicted SDs (odds ratio (OR), 25.78; 95% confidence interval (CI), 2.09, 318.10; P < 0.05) in participants. Conclusion: The prevalence of SD is significantly high among female participants. Hence, treating physicians should pay attention to sexual function during the screening and treatment of patients with schizophrenia.

The implications of the COVID-19 pandemic on eating disorder features and comorbid psychopathology among adolescents with anorexia nervosa and matched controls: a comparative cohort design study

PurposeTo examine implications of the COVID-19 pandemic on eating disorder (ED) features and psychopathology in female adolescents with anorexia nervosa (AN).MethodIn total 79 females with first-onset AN (aged 12–22 years) were included and were followed up across a period of 1 year. We assessed AN participants recruited pre-pandemic (n = 49) to those recruited peri-pandemic (n = 30). Pre- (n = 37) and peri-pandemic (n = 38) age-, and education-matched typically developing (TD) girls (n = 75) were used as a reference cohort. ED features and psychopathology were assessed at baseline. After 1 year of follow-up the association between pandemic timing and clinical course was assessed. Analyses of covariance were used to examine differences in ED features and psychopathology.ResultsPeri-pandemic AN participants experienced less ED symptoms at baseline compared to pre-pandemic AN participants. In particular, they were less dissatisfied with their body shape, and experienced less interpersonal insecurity. In addition, the peri-pandemic AN group met fewer DSM-IV criteria for comorbid disorders, especially anxiety disorders. In contrast, peri-pandemic AN participants had a smaller BMI increase over time. In TD girls, there were no differences at baseline in ED features and psychopathology between the pre- and peri-pandemic group.ConclusionOverall, peri-pandemic AN participants were less severely ill, compared to pre-pandemic AN participants, which may be explained by less social pressure and peer contact, and a more protective parenting style during the pandemic. Conversely, peri-pandemic AN participants had a less favorable clinical course, which may be explained by reduced access to health care facilities during the pandemic.Level of evidenceLevel III: Evidence obtained from well-designed cohort or case–control analytic studies.

Risk Factor Analysis of Drug-Resistant Tuberculosis in Tuberculosis Patients at Level II Health Facilities in Depok City

Based on Global Tuberculosis Report In 2022, Indonesia will be among the 10 countries contributing to the highest incidence of drug-resistant tuberculosis each year. There are 12,794 cases of drug-resistant tuberculosis in Indonesia with 7,884 cases starting treatment. The number of drug-resistant tuberculosis cases involves a variety of risk factors. This study aims to analyze the risk factors associated with drug-resistant tuberculosis. The research method is observational analytic design case control study. The research samples were patients with drug-resistant tuberculosis and drug-sensitive tuberculosis in Depok City Health Facilities for the period March 2022–May 2023. Data were collected using questionnaires and SITB (Tuberculosis Information System). Bivariate analysis using Chi Square, while multiple logistic regression multivariate analysis. The results of the study of 73 cases and 73 controls showed that the majority were aged 18 - 65 years, 89% of cases and 62% of controls, male gender was the most dominant, 64.4% of cases and 52% of controls, most of the respondents did not work 68.5 % of cases and 53.4% ​​of controls, most of them had low income, 82.8% of cases and 62% of controls. Most of the case group had a high level of education, namely 58.5%. Meanwhile, most of the control group had low education, 50.7%. Bivariately, risk factors associated with drug-resistant tuberculosis are HIV, history of previous treatment, adherence to taking medication and the role of drug swallowing supervisor (PMO). Based on multivariate analysis, the dominant variable associated with the incidence of drug-resistant tuberculosis is history of previous treatment (OR6.021 with CI 2.055-18.721) meaning that patients with a history of previous treatment have a 6 times risk of developing drug-resistant tuberculosis compared to patients without a history of previous treatment.

The importance of factors early in life for development of eating disorders in young people, with some focus on type 1 diabetes

AimEating disorders have a serious impact on quality of life, especially when combined with Type 1 diabetes. We investigated eating disorders in relation to factors early in life with some focus on Type 1 diabetes.MethodsOut of 21,700 children born 1st of Oct 1997–1st of Oct 1999 17,055 (78.6%) were included in ABIS (All Babies in southeast Sweden) and 16,415 had adequate questionnaires. ICD-10 diagnosis from The National Patient Register was merged with the ABIS data.ResultsIn total 247 individuals, 19 boys (7.7%) and 219 girls (92.3%) out of 16,415 (1.5%) developed eating disorders (EDs), 167 (1.0%) Type 1 diabetes of whom 7 (4.2%) also got eating disorders (ED) (OR 3.25 (1.47–7.28); p = 0.04), all of them years after diagnosis of Type 1 diabetes. EDs was associated with high parental education especially in fathers (OR 1.65 (1.09–2.50); p = 0.02) and to at birth anxiety, and depression among mothers. There was no association with the duration of breastfeeding.ConclusionsEating disorders are common in girls, with increased risk in high-educated but psychologically vulnerable families. Prevalence is increased in type 1 diabetes. Even modern diabetes treatment needs to be completed with psychological support.Level of evidenceLevel III: Evidence obtained from well-designed cohort or case–control analytic studies.

The influence of occupational heat stress on serum inflammatory cytokines among traditional bakery workers in Iran.

Heat exposure exceeding the ISO7243:1989 standard limit can contribute to health problems among employees in a variety of workplaces. Ignoring heat standard requirements in hot working conditions such as bakeries results in physiologic and health problems, as well as an elevated risk of later illnesses. In this analytical case-control study, the serum levels of four inflammatory factors (interleukin-1 beta, interleukin-6, tumor necrosis factor-α, and C-reactive protein) were assessed using an enzyme-linked immunosorbent assay. 105 male artisan bakers (in four job classifications in bakeries and staff) were compared based on demographic characteristics and inflammatory factors. The findings of the study showed correlations between serum interleukin-1β, interleukin-6, and C-reactive protein levels and thermal exposure in the occupational environment and employment type. Moreover, some differences in serum level of interleukin-1β and job type were observed. Heat overexposure affected the increase of interleukin-1β and C-reactive protein secretion. As a result of years of working in high-temperature conditions, inflammation can lead to subsequent diseases in workers. To protect their health from this occupational hazard, additional safeguards are needed. Our recommendations could also be applied to overly hot work environments that may cause heat stress in workers.

Thresholds and variability of retinal light sensitivity in each point of the examined visual field

This study assesses the light sensitivity and its variability in each point of the visual field in patients without glaucoma and with different stages of glaucoma. The data of a prospective analytical case-control study involving 500 patients were analyzed. The initial examination of all patients was performed using basic ophthalmological methods, including static perimetry. Retinal light sensitivity and its variability were assessed in 54 points corresponding to the Humphrey 24-2 program. Mean deviation and pattern standard deviation of light sensitivity were calculated for each point. The lowest light sensitivity values in patients with moderate glaucoma were found in the periphery of the nasal sector, at point No. 27 - 14.4 dB, and at points No. 24-26 along the horizontal axis from the nasal side - from 17.7 to 22.7 dB. The maximum variability of light sensitivity was found in the nasal sector on both sides of the horizontal line - from 10.7 to 11.5 dB. The average light sensitivity above the horizontal axis in patients with advanced glaucoma was 10.8 dB, which is 2 dB higher than in the lower half of the visual field - 8.8 dB. The highest light sensitivity values were found at points No. 24 - 17.7 dB and No. 31 - 16.78 dB, the lowest - at point No. 32 - 4.5 dB. The average variability values of light sensitivity in the upper half of the visual field were 9.6 dB, which is 1 dB less than in the lower half of the visual field - 10.6 dB. According to our data, points No. 32 and No. 40 are of particular interest in the diagnostic plan. In these loci, the highest light sensitivity values were determined in early and moderate glaucoma. However, the values in these points decrease significantly in advanced glaucoma. It can be assumed that changes in light sensitivity in these loci at the early stages of glaucoma may be a predictor of glaucoma progression.

Clinical assessment of the severity of bronchopulmonary dysplasia in children born prematurely

Bronchopulmonary dysplasia (BPD) – chronic lung disease, which evolves with broncho-obstructive syndrome, signs of respiratory failure, pulmonary fibrosis. Aim. Analytical case-control study included 41 children with BPD and 40 preterm children without BPD, who were clinically evaluated. Methods. Evaluation of clinical respiratory syndromes and degree of severity of bronchopulmonary dysplasia in premature infants. Results. The study demonstrated that the O2 saturation determined by pulse oximetry in premature children with BPD is reduced - 94.5±0.4%, compared to the O2 saturation of premature children without BPD (97.85±0.14%), which is significantly higher (F stat = 66.7, T stat = 8.17, p<0.0001). Children with mild grade BPD present intercostal retractions in 22.2%: 95%CI 2.8-60, in moderate grade BPD – 52.6%: 95%CI 28.9-75.6 and in severe grade DBP all the children had chest retractions. Depending on the degrees of severity, children with mild BPD present intercostal retractions in 22.2%, in moderate BPD – 73.7% and in severe BPD all children had intercostal retractions. Costal retractions, which is an indicator of respiratory insufficiency, was found in all preterm infants with severe BPD, in 52.6%: 95%CI 28.9-75.6 preterm infants with moderate BPD. Premature children with mild BPD did not present costal retractions at the stage of diagnosis confirmation (χ2 = 15.3; p<0.001). Conclusions. According to the study, bronchopulmonary dysplasia in children born prematurely is manifested by signs of respiratory insufficiency - accelerated breathing, intercostal and thoracic retractions, low values of O2 saturation. The severity of signs of respiratory impairment is dependent on the degree of bronchopulmonary dysplasia, having a clinical expression through different forms of thoracic retractions.

Role of point-by-point light sensitivity in the assessment of glaucoma progression

This study analyzes changes in light sensitivity in each test point of the visual field in patients with different stages of glaucoma. The data of a prospective analytical case-control study were analyzed. All patients underwent assessment of retinal light sensitivity and its variability in 54 points corresponding to the 24-2 program. Mean light sensitivity values were calculated in each point. Intergroup analysis was performed to evaluate changes in light sensitivity in each point. The range of light sensitivity decrease in the early glaucoma group compared to the control group was from 1.5 to 3.6 dB. The range of light sensitivity decrease in the moderate glaucoma group compared to the control group was from 2.1 to 11.5 dB, and compared to the early glaucoma group - from -0.9 to 7.9 dB. The most frequent decrease in light sensitivity was detected in the nasal sector and along the horizontal line in the upper half of the visual field. This trend persisted within the central 10 degrees of the visual field. The range of light sensitivity decrease in the advanced glaucoma group compared to the control group was from 14.1 to 28.0 dB, and compared to the early glaucoma group - from 11.35 to 26.08 dB, compared to the moderate glaucoma group - from 9.1 to 23.5 dB. The most frequent and severe decrease in light sensitivity was detected in the paracentral zone in the lower half of the visual field. The study analyzed the trends in the development of glaucoma from the early to the advanced stage. The most frequent and severe defect in light sensitivity in cases of verified advanced glaucoma was found in the lower half of the visual field. Points No. 32, 33 and 40 can be indicated as the area of interest in assessing the progression of glaucoma, as they were found to have the most profound changes in light sensitivity as glaucoma progressed.

Sleep is the best medicine: assessing sleep, disordered eating, and weight-related functioning

Sleep quality is linked to disordered eating, obesity, depression, and weight-related functioning. Most research, however, has focused on clinical populations. The current study investigated relationships between sleep quality, disordered eating, and patterns of functioning in a community sample to better understand relationships among modifiable health behaviors. Participants (N = 648) recruited from Amazon Mechanical Turk completed assessments of eating, depression, weight-related functioning, and sleep. Self-reported height and weight were used to calculate body mass index (M = 27.3, SD = 6.9). Participants were on average 37.6 years (SD = 12.3), primarily female (65.4%), and White, not Hispanic (72.7%). Over half of participants endorsed poor sleep quality, and average sleep scores were above the clinical cutoff for poor sleep quality. Sleep scores were significantly positively correlated with disordered eating, depression, and weight-related functioning, even after adjusting for age, body mass index, and sex. Multivariate regression models predicting weight-related functioning and depression showed that both sleep quality and disordered eating independently predicted depression. Sleep quality did not independently predict weight-related functioning; however, disordered eating did. To the best of our knowledge, this is the first study to assess sleep behaviors, disordered eating, and weight-related functioning in a community sample of weight diverse participants. Results indicate that most participants endorsed poor sleep quality, which was associated with disordered eating patterns, including binge eating and poorer weight-related functioning, even after controlling for body mass index, highlighting that this relationship exists across the weight spectrum. These results speak to the importance of health behavior assessment and intervention within nonclinical samples.Level of evidence Level III: evidence obtained from well-designed cohort or case–control analytic studies

Haptoglobin gene polymorphism and iron profile in sickle cell disease patients with inflammation in Yaounde, Cameroon.

Major sickle cell syndromes are the most common hemoglobinopathy in the world. The sickle cell patients are subjected to several factors causing inflammation, and the genetic identification of each individual allows to focus the possibility of allelic variations influence of a specific gene and then the polymorphism. This study aims at determining the distribution of HP gene (OMIM#140100) and their involvement on hematological parameters and the iron profile in the sickle cell patients presenting an inflammation condition during major sickle cell syndromes in Cameroun. A case-control analytical study has been conducted over a period of 6 months. Cases consisting of sickle cell patients in a situation of inflammation and control of non-inflamed sickle cell patients. The patients presenting major sickle cell syndromes, interned and/or followed at the Hematology Department of the Regional Hospital of Bafoussam and the Central Hospital of Yaoundé have been recruited. HP genotyping was carried out at the Laboratory for Public Health Research Biotechnologies (LAPHER-Biotech) in Yaoundé using allele-specific PCR. Also, inflammatory, hematological parameters and martial assessment were explored by standard methods. Statistical analysis of the data was performed using the statistical tool R version 4.1.1. The comparison of proportions of alleles was made with the chi-square test, and the Wilcoxon test was used to compare the median between different groups using the statistical tool R version 4.1.1. We analyzed the samples of 149 patients. The HP polymorphism describes a significant frequency of the "1F" allele (69.8%) followed by the "2" allele (46.31%). In addition, 80 patients (53.69%), 48 (32.21%), and 21 (14.09%) presented the genotype HP 1-1, HP 2-1, and HP 2-2, respectively. And eighty-one percent (81%) patients with genotype HP 2-2 showed a significant higher relative frequency of thrombocytosis compared with the genotype HP 1-1 and HP 2-1, respectively (51.2% and 68.8%, p = 0.087). The proportion of inflammation in the HP 2-2 group was higher (57.1%) compared with the other groups (respectively 42.5% and 35.4% in the HP 1-1 and HP 2-1 groups). Furthermore, the median CRP was significantly higher in the HP 2-2 group compared with the other groups (p = 0.039). Moreover, the entire population of the HP 2-2 group showed an elevation of ferritin and IL6 unlike the HP 1-1 and HP 2-1 groups. This study demonstrates a higher frequency of genotype HP 1-1 followed by the HP 2-2 genotype in patients with major sickle cell syndromes. However, a larger proportion of patients with genotype HP 2-2 are associated with hematological profile disorders, inflammation, and dysregulation of iron metabolism. Then, the haptoglobin polymorphism contributes to the severity of major sickle cell syndromes.

French validation of the Compensatory Eating and Behaviors in Response to Alcohol Consumption Scale (CEBRACS) in a university student sample

PurposeFood and Alcohol Disturbance (FAD) is characterized by the combination of problematic alcohol use and eating disorder symptoms to offset caloric intake associated with alcohol drinking and/or to enhance intoxication. The Compensatory Eating and Behaviors in Response to Alcohol Consumption Scale (CEBRACS) is a proven tool for measuring FAD, validated in English and Italian populations but never in the French population. The present study aims at validating a French version of the CEBRACS in a representative sample of university students and to determine its validity and reliability.Methods2267 university students completed the CEBRACS and measures of eating disorders, alcohol consumption and exercise.ResultsAn exploratory factor analysis revealed a 4-factor structure: enhancement of the effects of alcohol, dietary restraint and exercise, purging and vomiting and extreme fasting. The internal consistency for these subscales ranged from good to excellent. Correlations between the CEBRACS and eating disorders, alcohol and exercise measures revealed a good concurrent validity. No gender differences were found in the CEBRACS scores. Participants with a CEBRACS total score > 21 points were at higher risk for developing eating disorders and alcohol-related problems.ConclusionsThese findings highlight the reliability and validity of the French version of the CEBRACS. The distinct factors identified in the CEBRACS allow to distinguish between participants with different motives for engaging FAD behaviour and thus to prevent future development of eating and/or alcohol use disorders. The CEBRACS seems to be a relevant scale to capture FAD behaviors and thus to prevent negative and deleterious consequences.Level of evidence: Level III, evidence obtained from well-designed cohort or case–control analytic studies.

The Association Between Choroidal Thickness and Meniere's Disease: A Cross-Sectional Study.

To evaluate and compare choroidal thickness (CT) between patients with Meniere's disease (MD) and a control group. This case-control analytical study was conducted on 37 subjects with MD and 37 healthy subjects. Subfoveal CT (SCT), large choroidal vessel (LCV) layer thickness, and mean subfoveal LCV thickness/mean SCT ratio were measured using enhanced-depth imaging optical coherence tomography (EDI-OCT) in the eyes on the MD side (ipsilateral), the contralateral eyes, and the control group. A statistically significant difference was observed in the mean SCT values between the ipsilateral and control groups after adjustment for age, sex, and migraine (p = 0.04). Moreover, there was a statistically significant difference between the mean subfoveal LCV thickness values and the mean subfoveal LCV thickness/mean SCT ratio between the ipsilateral and control groups (p = 0.006, and p < 0.001, respectively). Patients with a duration of disease over three years had a greater mean subfoveal LCV thickness/mean SCT ratio (67.35 ± 11.56 and 60.66 ± 11.27, respectively), which was statistically insignificant (p = 0.08). We found a thicker choroid and Haller layer, and a greater subfoveal LCV thickness/SCT ratio on the MD side compared to the controls. Furthermore, patients with a greater duration of disease had a lower subfoveal LCV thickness/SCT ratio. These findings may reflect the role of the trigeminal vascular system (TVS) and neurovascular pathophysiology in MD patients. More extensive studies are required to reach more definitive conclusions about the association between CT and MD. 4 Laryngoscope, 134:1889-1893, 2024.

The Nepean Belief Scale (NBS) as a tool to investigate the intensity of beliefs in anorexia nervosa: psychometric properties of the Italian version

BackgroundPeople with anorexia nervosa (AN) show a peculiar impairment of insight regarding their condition, often manifesting a denial of extreme emaciation and sometimes hiding or underreporting socially undesirable abnormal eating patterns. Sometimes the intensity of the beliefs held by patients with AN reach a delusional intensity.ObjectivesIn this study, the Italian version of the Nepean Belief Scale was applied to a sample of patients diagnosed with AN to investigate the intensity of their beliefs and convictions and its clinical correlates.MethodsThe Nepean Belief Scale (NBS) was translated and adapted to Italian and applied to a sample of patients diagnosed with AN based on the Structured Clinical Interview for DSM-5 (SCID-5).ResultsThe Italian version of the 5-item NBS showed excellent reliability. Convergent validity was proved by negative association with levels of insight measured with the Schedule for the Assessment of Insight in Eating Disorders. Beliefs of delusional intensity were reported by 10% of participants. Those with a greater intensity of beliefs, either overvalued or delusional ideas, were more likely to report poorer general cognitive performances on the Montreal Cognitive Assessment. No association was observed between NBS score and age, body mass index, symptoms of eating disorders, body dissatisfaction, or levels of depression. Fear of weight gain and control seeking were the most often reported themes at the NBS.ConclusionsThe Italian version of the NBS is a reasonably reliable, valid, and usable tool for the multidimensional assessment of insight in AN.Level of evidence Level III, Evidence obtained from well-designed cohort or case–control analytic studies.

CORRELATION BETWEEN BIRTH WEIGHT AND STUNTING IN CHILDREN UNDER FIVE A CASE-CONTROL STUDY

Stunting is a condition in which children experience delayed growth and development due to poor nutrition, recurrent infections, and inadequate psychosocial stimulation. The prevalence of children under 5 affected by stunting in 2020 is 22.3% or 148.1 million children worldwide. The analytical case-control study was conducted to explore the prevalence of child stunting and determine the association between birth weight and stunting occurrence among children under 5 years. It shows statistically significant with a p-value of 0.009 (p-value 0.05). A history of birth weight 2500 gr babies have a 3,660 times greater risk of experiencing stunting compared to children under 5 who were born with birth weight ≥2500 gr (CI=95%). There was a significant association between birth weight and stunting incidence among children under 5 years.

Association of Leptin with Glucose Intolerance and Gestational Diabetes Mellitus in Pregnant Women: Prospective Analytical Case-Control Study.

This study aimed to investigate the use of leptin as a marker for gestational diabetes by analyzing any correlation between serum leptin levels versus oral glucose tolerance tests (at 24 to 28weeks of pregnancy) and increased body weight (during pregnancy). A total of 110 female cases (81 pregnant and 29 non-pregnant) were included in the study. The 81 pregnant cases were divided into 3 groups according to their oral glucose tolerance test results. A chi-square test was used for categorical variables. The distribution of numerical variables was tested with the Shapiro-Wilk test. ANOVA and a post-hoc Bonferroni test was used for parametric data. Kruskal-Wallis variance analysis was used for non-parametric data. The Mann-Whitney U-test was used for pairwise comparisons. Spearman correlation analysis and multivariate regression analysis were performed for the evaluation of the correlation analysis between the parameters. Oral glucose tolerance test results were compared with leptin levels with a cut-off value of 11.43 for leptin. The ROC curve demonstrated an 83.3% sensitivity and 72.1% specificity for leptin. Leptin may play a role in the pathophysiology of gestational diabetes mellitus. However, the relationship between leptin levels and maternal weight gain during pregnancy is still unknown.

A 4pL item response theory examination of perceived stigma in the screening of eating disorders with the SCOFF among college students

We examined the psychometric properties of the SCOFF, a screening instrument for eating disorders, with consideration of the perceived stigma of items that can produce socially desirable responding among a sample of college students. The results of the current study suggest evidence of the sufficient psychometric properties of the SCOFF in terms of confirmatory factor and item response theory analyses. However, two items of the SCOFF revealed that individuals who otherwise endorsed other items of the SCOFF were less likely to endorse the items of Fat and Food. It is hypothesized that this is the result of perceived stigma regarding those two items that prompts individuals to respond in a socially desirable way. A weighted scoring procedure was developed to counteract the performance of these two items, but the psychometric performance was only slightly better and there would be a clear tradeoff of specificity over sensitivity if utilized. Future research should consider other ways to counteract such perceived stigma.Level of evidence Level III: Evidence obtained from cohort or case–control analytic studies.

14-3-3η Proteins as a Diagnostic Marker, Disease Activation Indicator, and Lymphoma Predictor in Patients with Primary Sjögren Syndrome.

Primary Sjögren syndrome (PSS) is a chronic, autoimmune, and lymphoproliferative disease of the connective tissue. In patients with PSS, the risk of developing B-cell non-Hodgkin lymphoma (NHL) increases dramatically, with a prevalence of approximately 5%. The 14-3-3 protein isoforms are phospho-serin/phospho-threonine binding proteins associated with many malignant diseases. This study aimed to evaluate the relationship between disease activity parameters and markers predicting lymphoma development in patients with PSS and 14-3-3η proteins. This study was designed as an analytical case-control study. A total of 57 PSS patients and 54 healthy volunteers were included in the study. The European League Against Rheumatism (EULAR) Sjögren syndrome disease activity index (ESSDAI) was used to assess systemic disease activity in PSS. Receiver operating characteristic (ROC) analysis was used to test the diagnostic accuracy measures of the analytical results. Multivariable linear regression analysis was used to evaluate the effects of independent variables on the 14-3-3η protein. The 14-3-3η protein serum levels were found to be significantly higher in PSS (2.72 [2.04-4.07]) than healthy controls (1.73 [1.41-2.43]) (P<0.0001). A significant relationship was found between 14-3-3η protein levels and ESSDAI group (β=0.385, 95%CI=0.318-1.651, P=0.005), hypocomplementemia (C3 or C4) (β=0.223, 95% CI=0.09-1.983, P=0.048) and purpura (β=0.252, 95% CI=0.335-4.903, P=0.022), which are accepted as lymphoma predictors. A significant correlation was found between PSS disease activity score ESSDAI and 14-33η protein (β=0.496, 95% CI=0.079-0.244, P=0.0002). 14-3-3η proteins are potential candidates for diagnostic marker, marker of disease activity, and predictor of lymphoma in PSS patients.

Consequences of Type-2 diabetes mellitus and Malaria co-morbidity on sperm parameters in men; a case-control study in a district hospital in the Ashanti Region of Ghana.

Type-2 diabetes mellitus (T2DM) and malaria infection are highly prevalent in Africa particularly, in the Sub-Saharan Region. A greater number of people in the Ghanaian population who have T2DM are also reported to harbor malaria parasites. This study aimed to investigate the influence of T2DM & Malaria co-morbidity on sperm parameters among patients in the Ashanti Region of Ghana. This hospital-based cross-sectional analytic case-control study comprised 254 adult male study participants comprising 80 T2DM & Malaria co-morbidity, 80 T2DM only, and 94 normal controls. A blood sample (10mL) was drawn from each participant to measure FBG, HbA1c levels, Testosterone levels, Total cholesterol, and determination of Malaria parasite density. Seminal fluid was also collected from each participant for semen analysis. Sperm kinetics of the T2DM & Malaria co-morbidity group particularly; total motility, rapid progressive motility, and slow progressive motility were negatively affected compared to both T2DM only (p<0.0001) and the Normal control (p<0.0001). Normal sperm morphology was significantly affected in the co-morbidity group compared to T2DM only (p<0.0001). Sperm vitality was also statistically significantly reduced in the T2DM & Malaria co-morbidity than in T2DM only (t (64) = -8.62; p<0.001). There was a significant decline in testosterone levels in the T2DM & Malaria co-morbidity group than in the T2DM only (p<0.0001) and the control (p <0.0001). In conclusion, T2DM and malaria infection have a stronger propensity to alter sperm morphology and lower sperm motility and vitality.
