Leprosy in North India in Post-Elimination Era: A Retrospective Study

Abstract Background: India achieved elimination target for leprosy in December 2005. However, many pockets in the country continue to report significant number of cases. Aim: The aim of the study was to study the profile of leprosy cases presenting to a tertiary care hospital in North India in post-elimination era. Patients and Methods: The study was conducted at Hansen’s disease clinic. The study design was a retrospective observational study. Chart review of treatment naive leprosy patients enrolled between 1st January 2018 and 31st December 2019 was done. Data regarding demographic profile, clinical spectrum of leprosy, slit-skin smears (SSSs) and histopathological findings were analysed. Statistical Analysis: Statistical analysis was performed using the Statistical Package for the Social Sciences (SPSS) software version 23 (SPSS Inc., Chicago, IL, USA). Data were statistically described in terms of range, mean ± standard deviation, frequency (number of cases), and relative frequency (percentages). Results: Amongst a total of 115 patients, males (68%, n = 79/115) outnumbered females. Children (<15 years) constituted 0.86% cases (n = 1/115) and 26% cases (n = 30/115) were above 50 years of age. Multibacillary leprosy (73%, n = 84/115) was more common. Borderline lepromatous (41.7%, n = 48/115) was the most common clinical type of leprosy, whereas Grade 2 disability was noted amongst 0.05% (n = 6/115) patients at presentation. SSS were positive in 60% (69/115) cases. Conclusions: The present study showed a significant increase in cases in the older age group and decrease in new cases in children. Furthermore, multibacillary cases outnumbered the paucibacillary cases. Similar trends were reported to be an indicator of decreasing incidence of leprosy in countries that eliminated leprosy. We speculate that India may be entering a phase of decreased community transmission of leprosy. Further, multicentric studies across the country may throw more light.

Unveiling the negative association of Faecalibacterium prausnitzii with ischemic stroke severity, impaired prognosis and pro-inflammatory markers

BackgroundThe correlation between acute ischemic stroke (AIS) and gut microbiota has opened a promising avenue for improving stroke prognosis through the utilization of specific gut bacterial species. This study aimed to identify gut bacterial species in AIS patients and their correlation with stroke severity, 3-month prognosis, and inflammatory markers. Methods: We enrolled 59 AIS patients (from June 2021 to July 2022) and 31 age-matched controls with similar cerebrovascular risk profiles but no stroke history. Fecal samples were analyzed using 16 S rDNA V3–V4 sequencing to assess α and β diversity and identify significant microbiota differences. AIS cases were categorized based on the National Institute of Health Stroke Scale (NIHSS) scores and 3-month modified Rankin Scale (mRS) scores. Subgroup analyses were performed, and correlation analysis was used to examine associations between flora abundance, inflammatory markers and stroke outcome. ResultsSignificant differences in β-diversity were observed between case and control groups (P < 0.01). Bacteroides dominated AIS samples, while Clostridia, Lachnospirales, Lachnospiraceae, Ruminococcaceae, Faecalibacterium, and Faecalibacterium prausnitzii were prominent in controls. Faecalibacterium and Faecalibacterium prausnitzii were significantly reduced in non-minor stroke and 3-month poor prognosis groups compared to controls, while this difference was less pronounced in patients with minor stroke and 3-month good prognosis. Both Faecalibacterium and Faecalibacterium prausnitzii were negatively correlated with the NIHSS score on admission (r = −0.48, −0.48, P < 0.01) and 3-month mRS score (r = −0.48, −0.44, P < 0.01). Additionally, they showed negative correlations with pro-inflammatory factors and positive correlations with anti-inflammatory factors (both P < 0.01). ConclusionsFaecalibacterium prausnitzii is negatively associated with stroke severity, impaired prognosis, and pro-inflammatory markers, highlighting its potential application in AIS treatments.

Examine the Relationship between DMFT Index, Enamel Defects, and Oral Health-Related Quality of Life in Children with Celiac Disease

Background: Celiac disease (CD) is an autoimmune disorder that harms the epithelium and lamina propria of the small intestine in genetically predisposed individuals. Celiac disease negatively affects oral and dental health. Objectives: This research explored the DMFT index and enamel defects (ED), as well as their association with oral health-related quality of life in children with CD. Methods: In this descriptive-analytical cross-sectional study, 50 children with CD (case group) and 50 healthy children (control group) were examined. The World Health Organization criteria were used to determine the DMFT index. Aine's classification was employed to diagnose ED, and the standard CHILD-Oral Impacts on Daily Performances scale was used to assess child oral health-related quality of life (COHRQoL). The Chi-Square test and Mann-Whitney test were utilized for data comparison. P-values &lt; 0.05 were considered statistically significant. Results: The average DMFT was 2.58 ± 2.39 in the case group and 2.08 ± 1.61 in the control group. According to the Mann-Whitney U test, this difference was not statistically significant (P = .223). The frequency of ED in the case group was significantly higher at 52%, compared to 16% in the control group (P &lt; .001). Additionally, there was a significant difference in the frequency of ED between boys and girls in the two groups (P &lt; .001). The COHRQoL score in the case group, with an average of 24.44 ± 19.91, was significantly higher than that in the control group, which had an average of 13.35 ± 13.65 (P = .002). In both the case and control groups, a significant positive relationship was observed between the COHRQoL score in children and the DMFT index (P &lt; .001). There was also a significant relationship between the COHRQoL score in children with ED in both the case and control groups (P = 0.004). Conclusions: According to the results, there was no difference in the DMFT index between the 2 groups. However, as the DMFT index increased in both groups, the COHRQoL score also increased. The number of ED cases was higher in celiac patients, and this had a significant effect on the COHRQoL score. Additionally, the COHRQoL score was higher in celiac patients compared to the control group.

The relationship of kinesiophobia in patients with lymphedema: a case-control investigation.

Kinesiophobia and lymphedema appear to be related conditions, and it is important to understand this relationship, as many of the symptoms and comorbidities presented by individuals with lower limb lymphedema are prevented and treated through movement, thus constituting kinesiophobia as a barrier to intervention. The objective of this study is, therefore, to evaluate and analyze the kinesiophobic beliefs reported by individuals with and without lower limb lymphedema, regarding the agreement, severity and differences found, and to establish levels of kinesiophobia. A case-control study with a total sample of 80 participants (40 with lower limb lymphedema and 40 without) was performed. Both groups (with and without lymphedema) were characterized anthropologically, sociodemographically, and clinically. In the case group, lymphedema was evaluated. Participants in both groups completed the Tampa Scale for Kinesiophobia - 13 items (TSK-13). Individuals with lower limb lymphedema had higher TSK-13 scores than their matched group without lymphedema. The items belonging to the activity avoidance subscale had the highest agreement and score in both groups. Differences between groups were mainly established for items belonging to the somatic focus subscale, showing that individuals with lower limb lymphedema have kinesiophobic beliefs related to the perceived severity of their lymphedema. The prevalence of kinesiophobia was increased in both groups, but the severity was mild. Considering the apparent tendency of people with lower limb lymphedema to present kinesiophobia and movement-limiting beliefs regarding the condition, greater attention should be paid to its assessment, prevention and treatment from a multidisciplinary and multimodal perspective, which takes into account the multiplicity of factors inherent to kinesiophobia and lymphedema and thus reduce their impact on the management of lymphedema.

An integrated machine learning-based model for joint diagnosis of ovarian cancer with multiple test indicators

ObjectiveTo construct a machine learning diagnostic model integrating feature dimensionality reduction techniques and artificial neural network classifiers to develop the value of clinical routine blood indexes for the auxiliary diagnosis of ovarian cancer.MethodsPatients with ovarian cancer clearly diagnosed in our hospital were collected as a case group (n = 185), and three groups of patients with other malignant otolaryngology tumors (n = 138), patients with benign otolaryngology diseases (n = 339) and those with normal physical examination (n = 92) were used as an overall control group. In this paper, a fully automated segmentation network for magnetic resonance images of ovarian cancer is proposed to improve the reproducibility of tumor segmentation results while effectively reducing the burden on radiologists. A pre-trained Res Net50 is used to the three edge output modules are fused to obtain the final segmentation results. The segmentation results of the proposed network architecture are compared with the segmentation results of the U-net based network architecture and the effect of different loss functions and region of interest sizes on the segmentation performance of the proposed network is analyzed.ResultsThe average Dice similarity coefficient, average sensitivity, average specificity (specificity) and average hausdorff distance of the proposed network segmentation results reached 83.62%, 89.11%, 96.37% and 8.50, respectively, which were better than the U-net based segmentation method. For ROIs containing tumor tissue, the smaller the size, the better the segmentation effect. Several loss functions do not differ much. The area under the ROC curve of the machine learning diagnostic model reached 0.948, with a sensitivity of 91.9% and a specificity of 86.9%, and its diagnostic efficacy was significantly better than that of the traditional way of detecting CA125 alone. The model was able to accurately diagnose ovarian cancer of different disease stages and showed certain discriminative ability for ovarian cancer in all three control subgroups.ConclusionUsing machine learning to integrate multiple conventional test indicators can effectively improve the diagnostic efficacy of ovarian cancer, which provides a new idea for the intelligent auxiliary diagnosis of ovarian cancer.

The impact of recreational cannabinoid legalization on utilization in a pregnant population.

Marijuana potency and utilization both continue to increase across the United States. While the overall prevalence of cannabinoid utilization during pregnancy has been surveyed in various studies, the direct impact of changing governmental policies on pregnancy use is less characterized. Thus, we aimed to investigate how the legalization of recreational cannabinoid products impacted use during pregnancy in the state of New Mexico. Participants who had a live birth during two study epochs were included: pre-legalization (Epoch 1: 1 January 2019-31 March 2021) and post-legalization (Epoch 2: 1 November 2021-30 November 2022). Participants were further divided into case group [prenatal cannabinoid exposure (PCE)] vs. control (no PCE), with cases being identified by documented self-report or a positive laboratory toxicology test for cannabinoid use during pregnancy. A total of 1,191 maternal/infant dyads were included in Epoch 1, and 378 maternal/infant dyads were included in Epoch 2. In Epoch 1, 788 dyads were controls with 403 cases, while Epoch 2 had 292 controls and 86 cases. Interestingly there was a significant decrease in self-report or positive laboratory toxicology tests in Epoch 2 compared to Epoch 1. Infants born following PCE in both Epoch groups were more commonly born via Cesarean section, had significantly smaller birth weight, length, and head circumference as well as significantly lower Apgar scores at 1 and 5 min. The finding of decreased reported cannabinoid use in the post-legalization group is contradictory to previous studies which have shown increased rates of cannabinoid use after legalization. This could be due to multiple factors including changes in screening practices, the COVID-19 pandemic, and lack of commercialization of THC products. Additional studies are needed to further characterize how changing governmental policies impacts utilization during pregnancy.

Integrative ATAC-seq and RNA-seq analysis associated with diabetic nephropathy and identification of novel targets for treatment by dapagliflozin.

Dapagliflozin (DAPA) are clinically effective in improving diabetic nephropathy (DN). However, whether and how chromatin accessibility changed by DN responds to DAPA treatment is unclear. Therefore, we performed ATAC-seq, RNA-seq, and weighted gene correlation network analysis to identify the chromatin accessibility, the messenger RNA (mRNA) expression, and the correlation between clinical phenotypes and mRNA expression using kidney from three mouse groups: db/m mice (Controls), db/db mice (case group), and those treated with DAPA (treatment group). RNA-Seq and ATAC-seq conjoint analysis revealed many overlapping pathways and networks suggesting that the transcriptional changes of DN and DAPA intervention largely occured dependently on chromatin remodeling. Specifically, the results showed that some key signal transduction pathways, such as immune dysfunction, glucolipid metabolism, oxidative stress and xenobiotic and endobiotic metabolism, were repeatedly enriched in the analysis of the RNA-seq data alone, as well as combined analysis with ATAC-seq data. Furthermore, we identified some candidate genes (UDP glucuronosyltransferase 1 family, Dock2, Tbc1d10c, etc.) and transcriptional regulators (KLF6 and GFI1) that might be associated with DN and DAPA restoration. These reversed genes and regulators confirmed that pathways related to immune response and metabolism pathways were critically involved in DN progression.

Distribution of maternal risk factors for orofacial cleft in infants in Indonesia: a multicenter prospective study.

The pathogenesis of orofacial cleft (OFC) is multifactorial, involving both genetic and non-genetic factors, the latter of which play a key role in the development of these anomalies. This paper addresses the incidence of OFC in Indonesia, with a focus on identifying and examining the distribution of contributory factors, including parental medical history, pregnancy history, and environmental influences. The study was conducted through the collection of primary data. An interdisciplinary research team from Indonesia administered a standardized questionnaire to parents who had children with OFC and who had provided informed consent. The case group comprised 133 children born with cleft lip and/or palate, and the control was 133 noncleft children born full-term. The risk factors associated with OFC anomalies were analyzed using the chi-square test and logistic regression. All statistical analyses were performed using SPSS version 25. A p-value of 0.05 or less was considered to indicate statistical significance. The study comprised 138 children, of whom 82 were boys (59.4%) and 56 were girls (40.6%). Among them, 45 patients (32.6%) presented with both cleft lip and cleft palate, 25 individuals (18.1%) had a cleft palate only, and 28 patients (20.3%) had a cleft lip only. OFC was found to be significantly associated with a maternal family history of congenital birth defects (p< 0.05), complications during the first trimester (p< 0.05), consumption of local fish (p< 0.05), caffeine intake (p< 0.05), prolonged medication use (p< 0.05), immunization history (p< 0.05), passive smoking (p< 0.05), and X-ray exposure during pregnancy (p< 0.05). The findings indicate close relationships between the incidence of OFC and maternal medical history, prenatal factors, and environmental influences.

The Arg753Gln Polymorphisms in Toll-like Receptor 2 in a Syphilis-Infected and Control Population in The Netherlands: Can Differences in the Number of Self-Reported Sexual Contacts Indicate Protection against Syphilis?

The Arg753Gln polymorphism in Toll-like receptor 2 has been associated with an increased risk of bacterial infections as well as with protection from the late stages of Lyme disease and the acquisition of syphilis. In this study, we determined the presence of this polymorphism in samples collected from men having sex with men/men with women in the Amsterdam Cohort Studies. The presence of the polymorphism was determined by nested PCR, followed by Sanger sequencing. A set of 90 syphilis-seronegative individuals was compared to 95 syphilis-diagnosed participants. A polymorphism allele frequency of 3.9% was found in the control group and 2.63% in the syphilis case group, respectively. None of the individuals showed a homozygous Arg753Gln polymorphism. The number of self-reported sexual contacts was higher in the group of syphilis patients compared to the control group (p = 0.0063). Moreover, in the syphilis case group (n = 49), participants heterozygous for the TLR2-Arg753Gln reported higher numbers of sexual contacts (p = 0.037) compared to wild-type homozygotes. Our findings suggest a possible protective effect of TLR2-Arg753Gln in the acquisition of syphilis. In addition, the determination of the number of self-reported sexual contacts can be used in an evaluation of the protective effect of polymorphism in a population with a low prevalence of it.

Alterations in leukocyte telomere length and mitochondrial DNA copy number in benzene poisoning patients.

The aim of this study is to examine and evaluate the impact of benzene poisoning on the relative content of the mitochondrial MT-ND1 gene and telomere length in individuals with occupational chronic benzene poisoning (CBP) compared to a control group. The study will analyze and gather data on the mitochondrial gene content and telomere length in cases of benzene poisoning, and investigate the relationship with blood routine parameters in order to contribute scientific experimental data for the prevention and treatment of CBP. The case group comprised 30 individuals diagnosed with occupational chronic benzene poisoning, whereas the control group consisted of 60 healthy individuals who underwent physical examinations at our hospital concurrently. Blood routine indicators were detected and analyzed, and the PCR method was employed to measure changes in mitochondrial MT-ND1 content and telomere length. Subsequently, a comparison and analysis of the aforementioned indicators was conducted. The case group exhibited a higher mitochondrial gene content (median 366.2, IQR 90.0 rate) compared to the control group (median 101.5, IQR 12.0 rate), with a statistically significant difference between the two groups (P < 0.05). Additionally, the case group demonstrated lower white blood cell levels (3.78 ± 1.387 × 109/L) compared to the control group (5.74 ± 1.41 × 109/L), with a significant difference between the two groups (P < 0.05). Furthermore, the case group displayed lower red blood cell levels (3.86 ± 0.65 × 1012/L) compared to the control group (4.89 ± 0.65 × 1012/L), with a significant difference between the two groups (P < 0.05). The hemoglobin level in the case group (113.33 ± 16.34g/L) was lower than that in the control group (138.22 ± 13.22g/L). There was a significant difference between the two groups (P < 0.05). Platelet levels in the case group (153.80 ± 58.31 × 109/L) is smaller than the control group (244.92 ± 51.99 × 109/L), there was a significant difference between the two groups (P < 0.05). The average telomere length of the normal control group was 1.451 ± 0.475 (rate); The mean telomere length of individuals in the case group diagnosed with benzene poisoning was determined to be 1.237 ± 0.457 (rate). No significant correlation was observed between telomere length and three blood routine parameters, namely white blood cells (WBC), hemoglobin (HB), and platelets (PLT). However, a significant correlation was found between telomere length and red blood cell count (RBC). Additionally, a negative correlation was observed between mitochondrial gene content and white blood cell count (r = - 0.314, P = 0.026), as well as between mitochondrial gene content and red blood cell count (r = - 0.226, P = 0.032). Furthermore, a negative correlation was identified between mitochondrial gene content and hemoglobin (r = - 0.314, P = 0.028), and platelets (r = - 0.445, P = 0.001). Individuals diagnosed with occupational chronic benzene poisoning exhibit a reduction in telomere length and an elevation in the relative content of the mitochondrial MT-ND1 gene. Moreover, a negative correlation is observed between the content of the mitochondrial MT-ND1 gene and four blood routine parameters, namely white blood cells (WBC), red blood cells (RBC), hemoglobin (HB), and platelets (PLT). Consequently, benzene exposure may potentially contribute to the onset of premature aging.

Sex-specific difference in phenotype of Kabuki syndrome type 2 patients: a matched case-control study.

Kabuki syndrome (KS) is a monogenic disorder leading to special facial features, mental retardation, and multiple system malformations. Lysine demethylase 6A, (KDM6A, MIM*300128) is the pathogenic gene of Kabuki syndrome type 2 (KS2, MIM#300867), which accounts for only 5%-8% of KS. Previous studies suggested that female patients with KS2 may have a milder phenotype. We summarized the phenotype and genotype of KS2 patients who were diagnosed in Shanghai Children's Medical Center since July 2017 and conducted a 1:3 matched case-control study according to age and sex to investigate sex-specific differences between patients with and without KS2. There were 12 KS2 cases in this study, and 8 of them matched with 24 controls. The intelligence quotient (IQ) score of the case group was significantly lower than that of the control group (P < 0.001). In addition, both the incidence of intellectual disability (ID) (IQ < 70) and moderate-to-severe ID (IQ < 55) were significantly higher in the case group than those in the control group. No sex-specific difference was found in the incidence of ID or moderate-to-severe ID between the female cases and female controls, whereas there was a significant difference between male cases and male controls. Furthermore, the rate of moderate-to-severe ID and congenital heart disease (CHD) was significantly higher in the male group than that in the female group. Our results showed that a sex-specific difference was exhibited in the clinical phenotypes of KS2 patients. The incidence of CHD was higher in male patients, and mental retardation was significantly impaired. However, the female patients' phenotype was mild.

Assessment of sensitivity of acoustic reflex decay test in diagnosis of patulous eustachian tube

Abstract Background It has long been believed that the patulous eustachian tube is a unique but uncommon condition, with an estimated incidence ranging from 0.3 to 6.6% in the general population. Hearing one’s own voice and breathing, or autophony and aerophony, are the most common symptoms of PET, along with frequent auditory fullness. Aim This study is to establish a standardized protocol for the audiological evaluation of patulous Eustachian tube using acoustic reflex decay test during different breathing tasks. Methods Between January 2022 and December 2022, the ENT department at Suez Canal University Hospitals undertook an observational case-control study. Fifty-two adult patients who present to the Suez Canal University ENT department with complaints of autophony, auditory fullness, or aerophony are diagnosed with patulous eustachian tube dysfunction through endoscopic examination of the tympanic membrane’s synchronized movement with respiration. Results The incidence rate of PET among adults was approximately 3 patients/1000 patients/year. The age of the whole studied group ranged from 20 to 60 years with mean ± SD of 37.4 ± 12.6 years. They included 23 males (44.2%) and 29 females (55.8%). The most common symptom among the studied group was aural fullness (46%), while the least common symptom was aerophony (12%); the most common risk factor among the studied patients was allergy (46.2%), while the least common was radiotherapy (3.9%); 66.7% of the patients with GERD were males, while 66.7% of the patients who lost weight were females; 58.3% of the patients with allergies were females, and also 60% of the patients with thin built were females. In the case group, there is a significant higher change of middle ear compliance in ipsilateral nostril breathing than the mouth breathing and nasal breathing. The sensitivity of the acoustic reflex decay test to diagnose PET with reference to the gold standard test is 88.5% (23/26*100), the specificity is 100% (26/26*100), and the positive predictive value is 100% (23/23*100). Conclusion The sensitivity of the acoustic reflex decay test to diagnose PET with reference to the gold standard test is high, and the specificity is very high with very good diagnostic accuracy.

Vitamin D deficiency and oral candidiasis in patients with HIV infection: A case‒control study.

Oral candidiasis is a common opportunistic infection in patients with human immunodeficiency virus (HIV). In addition, most of these patients suffer from vitamin D deficiency. This study aimed to investigate the association between vitamin D levels and oral candidiasis in patients with HIV infection. This case‒control study was conducted on HIV-infected patients. Cases were patients with oral candidiasis diagnosed based on physical examinations. Controls were age- and sex-matched individuals without oral candidiasis. The levels of 25-OH vitamin D and other laboratory markers (CD4 count and viral load) were compared between the case and control groups. A total of 104 cases and 102 controls were included in the study. The cases had significantly lower 25-OH vitamin D3 levels (MD = 33.86 ng/mL, 95% CI= (31.85, 35.87), P < 0.001) and CD4 counts (MD = 267.48 cells/mm3, 95% CI= (189.55, 345.41), P < 0.001) than the controls. In addition, viral load was significantly higher in cases than in controls (MD = 7.03 × 105 copies/mL, 95% CI= (4.46 × 105, 9.61 × 105), P < 0.001). The multivariate logistic regression analysis revealed that educational status (OR = 0.032, 95% CI= (0.002, 0.100), P < 0.001), current HAART (OR = 0.005, 95% CI= (0.001, 0.014), P < 0.001), history of oral candidiasis (OR = 20.114, 95% CI= (18.135, 21.957), P < 0.001), CD4 count (OR = 0.004, 95% CI= (0.001, 0.006), P < 0.001), viral load (OR = 12.181, 95% CI= (1.108, 133.392), P < 0.001), and vitamin D level (OR = 0.011, 95% CI= (0.008, 0.015), P < 0.001) were significantly associated with the risk of developing oral candidiasis. Based on the findings, most patients with HIV infection suffer from vitamin D deficiency, especially those with oral candidiasis. Hypovitaminosis D was significantly associated with an increased risk of oral candidiasis. Thus, vitamin D supplementation may assist HIV-positive patients in improving their oral health and preventing oral candidiasis.

Impaired implicit emotion regulation in patients with panic disorder: An event-related potential study on affect labeling.

Panic disorder (PD) involves emotion dysregulation, but its underlying mechanisms remain poorly understood. Previous research suggests that implicit emotion regulation may play a central role in PD-related emotion dysregulation and symptom maintenance. However, there is a lack of studies exploring the neural mechanisms of implicit emotion regulation in PD using neurophysiological indicators. To study the neural mechanisms of implicit emotion regulation in PD with event-related potentials (ERP). A total of 25 PD patients and 20 healthy controls (HC) underwent clinical eva-luations. The study utilized a case-control design with random sampling, selecting participants for the case group from March to December 2018. Participants performed an affect labeling task, using affect labeling as the experimental condition and gender labeling as the control condition. ERP and behavioral data were recorded to compare the late positive potential (LPP) within and between the groups. Both PD and HC groups showed longer reaction times and decreased accuracy under the affect labeling. In the HC group, late LPP amplitudes exhibited a dynamic pattern of initial increase followed by decrease. Importantly, a significant group × condition interaction effect was observed. Simple effect analysis revealed a reduction in the differences of late LPP amplitudes between the affect labeling and gender labeling conditions in the PD group compared to the HC group. Furthermore, among PD patients under the affect labeling, the late LPP was negatively correlated with disease severity, symptom frequency, and intensity. PD patients demonstrate abnormalities in implicit emotion regulation, hampering their ability to mobilize cognitive resources for downregulating negative emotions. The late LPP amplitude in response to affect labeling may serve as a potentially valuable clinical indicator of PD severity.

Development of a Prediction Model to Identify the Risk of Clostridioides difficile Infection in Hospitalized Patients Receiving at Least One Dose of Antibiotics.

This study's objective was to develop a risk-prediction model to identify hospitalized patients at risk of Clostridioides difficile infection (CDI) who had received at least one dose of systemic antibiotics in a large tertiary hospital. This was a retrospective case-control study that included patients hospitalized for more than 2 days who received antibiotic therapy during hospitalization. The study included two groups: patients diagnosed with hospital CDI and controls without hospital CDI. Cases were matched 1:3 with assigned controls by age and sex. Descriptive statistics were used to identify the study population by comparing cases with controls. Continuous variables were stated as the means and standard deviations. A multivariate analysis was built to identify the significantly associated covariates between cases and controls for CDI. A total of 364 patients were included and distributed between the two groups. The control group included 273 patients, and the case group included 91 patients. The risk factors for CDI were investigated, with only significant risks identified and included in the risk assessment model: age older than 70 years (p = 0.034), chronic kidney disease (p = 0.043), solid organ transplantation (p = 0.021), and lymphoma or leukemia (p = 0.019). A risk score of ≥2 showed the best sensitivity, specificity, and accuracy of 78.02%, 45.42%, and 78.02, respectively, with an area under the curve of 0.6172. We identified four associated risk factors in the risk-prediction model. The tool showed good discrimination that might help predict, identify, and evaluate hospitalized patients at risk of developing CDI.

Association of Diabetic Retinopathy and Sleep Quality

Sleep disorders are more common in diabetes mellitus (DM) cases rather than normal ones. In addition, this condition could be associated with diabetic retinopathy (DR) development with more inflammatory indices in circulation. In the present study, we have evaluated the association between DR and sleep quality. This cross-sectional study is a part of the second phase of the study of the elderly cohort of Amirkola City, which was conducted in 2015-2016 on all people aged 60 and higher. Of all diabetic cases, 44 cases had retinopathy and were selected as the case group. To compare two control groups, 135 diabetic patients without retinopathy and 135 people without diabetes were randomly selected. The presence and type of retinopathy were determined based on an eye physical examination by an ophthalmologist. In addition, sleep quality was evaluated based on the Pittsburgh Questionnaire. The obtained data were analyzed by ANOVA, t-test, and linear regression tests. In the present study, there was a significant difference in the score of the Pittsburgh questionnaire between people with DR (45.5±68.2) compared to diabetic people without retinopathy (76.5±48.2) and people without diabetes (95.4±36.2) (P=0.470), but diabetic people without retinopathy had significantly worse sleep quality than people without diabetes (P=0.019). Also, sleep quality in women with DR was worse than in men (P=014). In the linear regression analysis, it was observed that age, gender, diabetes, and history of depression significantly affect the sleep quality of the evaluated cases (P&lt;0.05 for all). According to the results of the present study, DR does not negatively influence the quality of sleep, and DR is not related to sleep disorders.

Vitamin D Status, VDR, and TLR Polymorphisms and Pulmonary Tuberculosis Epidemiology in Kazakhstan.

Tuberculosis (TB) and vitamin D deficiency remain major public health problems in Kazakhstan. Due to the high incidence of pulmonary tuberculosis in the country and based on the importance of vitamin D in the modulation of the immune response and the association of its deficiency with many health conditions, the aim of our research was to study the vitamin D status, VDR and TLR gene polymorphisms, and pulmonary tuberculosis epidemiology in Kazakhstan. A case-control study included 411 individuals diagnosed with pulmonary TB and 686 controls with no family history of pulmonary tuberculosis. Concentrations of serum vitamin D (25-(OH)D) levels were measured by electrochemiluminescence immunoassay. The gene polymorphisms were determined by real-time polymerase chain reaction (PCR) allelic discrimination assay using TaqMan probes. The association between the risk of pulmonary TB and polymorphisms was evaluated using multimodal logistic regression and assessed with the ORs, corresponding to 95% Cis, and the significance level was determined as p < 0.05. 1097 individuals were recruited from 3 different regions of Kazakhstan. Biochemical data showed vitamin D deficiency (25-(OH)D < 20 ng/mL) was present in both groups, with the case group accounting for almost 95% and 43.7% in controls. Epidemiological data revealed that socioeconomic factors such as BMI < 25 kg/m2 (p < 0.001), employment (p < 0.001), diabetes (p < 0.001), and vitamin D deficiency (p < 0.001) were statistically different between case and control groups. Logistic regression analysis, adjusted by sex, age, BMI, residence, employment, smoking, alcohol consumption, and diabetes, showed that T/T polymorphism of the VDR gene (rs1544410, OR = 1.97, 95% CI: 1.04-3.72, p = 0.03) and A/A polymorphism of the TLR8 gene (rs3764880, OR = 2.44, 95% CI: 1.20-4.98, p = 0.01) were associated with a high risk of developing pulmonary tuberculosis. Vitamin D deficiency remains prevalent in our study cohort and is associated with TB progression. Socioeconomic determinants such as unemployment, BMI under 25 kg/m2, and diabetes are the main risk factors for the development of pulmonary TB in our study. A/A polymorphism of TLR8 (rs3764880) and T/T polymorphism (BsmI, rs1544410) of VDR genes may act as biomarkers for pulmonary tuberculosis in the Kazakh population.

The body mass index and the risk of ectopic pregnancy: a 5-year retrospective case-control study

PurposeAcknowledging the associated risk factors may have a positive impact on reducing the incidence of ectopic pregnancy (EP). In recent years, body mass index (BMI) has been mentioned in research. However, few studies are available and controversial on the relationship between EP and BMI.MethodsWe retrospectively studied the EP women as a case group and the deliveries as a control group in the central hospital of Wuhan during 2017 ~ 2021. χ2 test of variables associated with ectopic pregnancy was performed to find differences. Univariate and multivariate binary logistic regression analysis was conducted to analyze the association of the variables of age, parity, history of induced abortion, history of ectopic pregnancy, history of spontaneous abortion, history of appendectomy surgery and BMI (< 18.5 kg/m2, 18.5 ~ 24.9 kg/m2, 25 kg/m2 ~ 29.9 kg/m2, ≥ 30 kg /m2) with EP.ResultsThey were 659 EP and 1460 deliveries. The variables of age, parity, history of induced abortion, history of ectopic pregnancy and BMI were different significantly(P < 0.05). Multivariate analysis showed that the variables of age > 35 years old [(OR (Odds Ratio), 5.415; 95%CI (Confidence Interval), 4.006 ~ 7.320, P < 0.001], history of ectopic pregnancy (OR, 3.944; 95%CI, 2.405 ~ 6.467; P < 0.001), history of induced abortion(OR, 3.365; 95%CI, 2.724 ~ 4.158, P < 0.001) and low BMI (< 18.5 kg/m2) (OR, 1.929; 95%CI, 1.416 ~ 2.628, P < 0.001])increased the risk of EP.ConclusionThe history of ectopic pregnancy, history of induced abortion and age > 35 years old were the risk factors with EP. In addition to these traditional factors, we found low BMI (< 18.5 kg/m2) with women may increase the risk to EP.

Association of dietary inflammatory index with C-reactive protein and interleukin-6 in women with and without polycystic ovarian syndrome

Considering that interventions related to lifestyle, especially nutrition have been proposed as the first line of prevention and treatment of polycystic ovarian syndrome (PCOS), and regarding the proven relationship between PCOS and inflammation, the present study was designed to find out the possible association of Diet Inflammatory Index (DII) with the inflammatory markers like C-reactive protein (CRP) and Interleukin-6 (IL-6), and compare the obtained results in PCOS and non-PCOS women. This case–control study was conducted on 45 PCOS and 40 non-PCOS women. Food intake and DII were measured using a 147-item Food Frequency Questionnaire. All participants were tested for the serum levels of IL-6 and CRP. Finally, the obtained results were compared between the two groups of PCOS and non-PCOS women. Significant differences were observed between the two groups in terms of age, menstrual status and number of pregnancies (P < 0.05). Comparison of DII values showed no significant difference between the two groups of women (P = 0.68), but IL-6 was significantly higher in the PCOS group than in the control group (4.94 ± 1.97 vs. 3.48 ± 1.77, P < 0.001). Also in terms of CRP, no significant difference was observed between the two groups (P > 0.05). The difference of DII between the case and control groups were not significant and Pearson's correlation test did not show a significant correlation between DII and IL-6 (P˃0.05). This result can be due to the influence of several factors affecting the determination of DII such as education level, health status, physical activity level, age, and calorie intake. It seems that diet, especially consumption of more carbohydrates plays a role in causing chronic inflammation, as well as the occurrence and exacerbation of PCOS.

Investigation of the effects of Gamma Knife radiosurgery on optic pathways using diffusion tensor MRI within the first year after treatment.

To investigate the radiation-induced effects of Gamma Knife radiosurgery (GKRS) for sellar-parasellar tumors on optic pathways using DTI parameters within the first year after treatment. Twenty-five patients with sellar-parasellar tumors underwent MRI before and 3months after GKRS, including T1WI, DTI, T2WI. Moreover, 21 patients underwent follow-up DTI 6-8months after radiosurgery. ROIs were set on optic nerves, optic radiations, and control localizations; DTI parameters for each were calculated. Pre- and post-radiosurgery differences in DTI values were statistically compared and assessed with respect to tumor size changes. Following GKRS, DTI parameters, notably ADC, FA, and RD, showed statistically significant changes in optic nerves and anterior optic radiations. DTI changes were more significant in the group of cases with tumor shrinkage. In this group, DTI of the anterior optic radiations further deteriorated 3months post-GKRS, whereas acute changes in DTI parameters of the optic nerves resolved within 6-8months. DTI of central and posterior optic radiations did not differ significantly following radiosurgery; 6-8months after radiosurgery, visual function was stable in 14 (56%) patients and improved in 11 (44%), showing no correlation with tumor size changes or DTI parameters. White Matter (WM) injury in the optic pathways can be induced by Gamma Knife radiosurgery targeted to sellar and parasellar tumors. Following GKRS, microstructural abnormalities occurred in the optic radiations as well as the optic nerves within the first post-treatment year. Our findings could support modifications to radiosurgical treatment strategies to minimize the risk of permanent WM injury.
