ABSTRACT

Inflammatory rheumatological conditions, also known as inflammatory rheumatic conditions (IRC), constitute a category of autoimmune and inflammatory ailments primarily affecting the musculoskeletal system, encompassing the joints, muscles, and connective tissues. The objective of this meta-analysis is to evaluate the impact of inflammatory rheumatological conditions (IRC) on post-acute coronary syndrome (ACS) outcomes. This study was performed as per the preferred reporting items for systematic review and meta-analysis (PRISMA) guidelines. The PubMed, Web of Science, and Scopus databases were searched by two authors without any language constraints from January 1, 2015, to October 15, 2023. The primary outcome assessed in this meta-analysis was all-cause mortality. Other outcomes included myocardial infarction and revascularization. A total of 11 studies were included in this meta-analysis. The risk of all-cause mortality was significantly higher in patients with IRC compared to non-IRC patients (RR: 1.12, 95% CI: 1.00 to 1.26, p-value: 0.04). There is a significantly higher risk of myocardial infarction and revascularization in patients with IRC as opposed to those without IRC. Furthermore, while there was a higher risk of stroke in the IRC group compared to the non-IRC group, this disparity did not reach statistical significance. Future research should focus on specific inflammatory rheumatoid conditions, a comprehensive evaluation of cardiovascular events, and targeted interventions to enhance patient outcomes in this vulnerable population.

ABSTRACT

Background Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women, often associated with metabolic issues like obesity and insulin resistance. Lifestyle changes, including weight loss, healthy eating, and regular exercise, are recommended for PCOS management. Studies have explored women’s perspectives on these changes, revealing misconceptions and adherence challenges. Recognizing the importance of individualized interventions, particularly addressing knowledge gaps, is vital for improving the quality of life for women with PCOS, especially in cultural contexts like Saudi Arabia. Methodology This was a cross-sectional study conducted in Saudi Arabia from May to August 2023 including PCOS patients. Data was collected through questionnaires and analyzed using IBM SPSS 29 (IBM Corp. Released 2020. IBM SPSS Statistics for Windows, Version 27.0. Armonk, NY: IBM Corp). This study was conducted in accordance with the ethical guidelines and principles outlined by the Scientific Research Ethics Committee of Taif University (no.44-359). All participants provided informed consent, and the study protocols, including data collection, analysis, and publication, adhered to the relevant ethical standards. Results Our study included a majority aged 18-29 (27.4%), married individuals (55.6%) and those with a Bachelor’s degree (72%). About 46.9% were medically diagnosed with PCOS. A notable proportion (70.2%) reported no family history of PCOS. Doctors were the primary information source (40.7%). Knowledge about PCOS was generally high, with correct recognition of various PCOS characteristics and treatment options. Attitudes were positive, especially among medically diagnosed individuals, and 91% believed weight reduction could improve PCOS symptoms. Lifestyle modification knowledge, attitude, and practices showed significant associations with demographic factors like age, place of residence, education, marital status, working in healthcare sectors, and PCOS diagnosis status. Conclusions Knowledge about PCOS is generally high among women with positive attitudes toward its management through lifestyle modifications. Women generally show positive practices of lifestyle modifications in PCOS, and they are associated with sociodemographic features.

ABSTRACT

OBJECTIVE: This study aimed to conduct a comprehensive 16-year analysis of years of potential life lost (YPLL) due to leading causes of death in the United States, focusing on disparities by sex, race/ethnicity, and specific causes of death using the National Center for Health Statistics (NCHS) data.

METHODS: Data from the NCHS spanning 2000-2016 were included. Age-adjusted YPLL rates per 100,000 population were analyzed, stratified by sex, race/ethnicity, and leading causes of death, including malignant neoplasms, heart disease, and cerebrovascular diseases.

RESULTS: Over 16 years, the total YPLL rate was 7,036.2 per 100,000 population. Males had a higher YPLL rate (8,852.5 per 100,000) than females (5,259.9 per 100,000). Among racial/ethnic groups, Black/African Americans had the highest YPLL rate (10,896.8 per 100,000), followed by American Indian/Alaska Natives (7,310.0 per 100,000), Hispanics/Latinos (5,256.8 per 100,000), and Asians/Pacific Islanders (3,279.7 per 100,000). Leading causes included malignant neoplasms (1,451.6 per 100,000), heart diseases (1,055.4 per 100,000), and cerebrovascular diseases (182.3 per 100,000).

CONCLUSION: This analysis spanning 16 years highlights notable disparities in YPLL rates among different demographic groups. These differences are evident in the YPLL rates for males, which are higher than those for females. The YPLL rate is most pronounced among Black/African Americans, followed by American Indian/Alaska Natives, Hispanics/Latinos, and Asians/Pacific Islanders. The primary contributors to YPLL are malignant neoplasms, heart diseases, and cerebrovascular diseases. These findings emphasize the importance of addressing these disparities to enhance public health outcomes and mitigate the premature loss of life. Despite progress, disparities persist, highlighting the need for targeted interventions and further research.

ABSTRACT

Introduction Sutures play a crucial role in the postoperative healing process, as they help approximate wound edges, promote hemostasis, and support tissue healing. The oral cavity harbors a diverse microbial population, and oral surgical procedures can introduce potential pathogens into the surgical site. Understanding the impact of suture material on wound infection rates and the colonization of potentially harmful microorganisms is vital for improving patient outcomes. This study was aimed to evaluate and compare the microbiological properties of prolene, vicryl plus, monocryl, and silk sutures used after the surgical removal of impacted lower third molars. Materials and methods A total of 40 patients requiring surgical extraction of impacted lower third molars were assigned to four groups: prolene, vicryl plus, monocryl, and silk sutures. Surgical extraction of impacted tooth was done, and wound was sutured with the abovementioned four different materials in four groups, respectively. After seven days, the sutures were removed and sent to the microbiology lab for colony count assessment. Total microbial colony count, streptococcus count, and lactobacillus count were assessed. Data was analyzed using IBM SPSS Statistics for Windows, Version 23.0 (Released 2015; IBM Corp., Armonk, New York, United States) with p-values less than 0.05 considered as statistically significant. The one-way analysis of variance (ANOVA) and post-hoc Tukey test were done to compare intergroup relations. Results The microbiological evaluation of the sutures revealed significant differences in bacterial colonization among the four groups. More bacterial quantities were found in the silk group followed by the monocryl, vicryl plus, and prolene groups in the descending order. Prolene demonstrated the lowest incidence of bacterial growth (p<0.001) compared to vicryl plus, monocryl, and silk sutures. Bacterial colony count was highest in the silk group. The predominant bacterial species found in all groups were Streptococcus viridans, Staphylococcus aureus, and Lactobacillus. Conclusion It was found that prolene and vicryl plus sutures exhibited superior microbiological properties compared to monocryl and silk sutures when used for the surgical removal of impacted lower third molars. The lower incidence and less quantity of bacterial colonization on prolene sutures suggest their potential for reducing the risk of postoperative infection; hence, these sutures can be preferred for oral surgical procedures.

ABSTRACT

BACKGROUND AND OBJECTIVE: Transcranial Burst Electrical Stimulation (tBES) is an innovative non-invasive brain stimulation technique that combines direct current (DC) and theta burst stimulation (TBS) for brain neuromodulation. It has been suggested that the tBES protocol may efficiently induce neuroplasticity. However, few studies have systematically tested neuromodulatory effects and underlying neurophysiological mechanisms by manipulating the polarity of DC and TBS patterns. This study aimed to develop the platform and assess neuromodulatory effects and neuronal activity changes following tBES.

METHODS: Five groups of rats were exposed to anodal DC combined with intermittent TBS (tBES+), cathodal DC combined with continuous TBS (tBES-), anodal and cathodal transcranial direct current stimulation (tDCS+ and tDCS-), and sham groups. The neuromodulatory effects of each stimulation on motor cortical excitability were analyzed by motor-evoked potentials (MEPs) changes. We also investigated the effects of tBES on both excitatory and inhibitory neural biomarkers. We specifically examined c-Fos and glutamic acid decarboxylase (GAD-65) using immunohistochemistry staining techniques. Additionally, we evaluated the safety of tBES by analyzing glial fibrillary acidic protein (GFAP) expression.

RESULTS: Our findings demonstrated significant impacts of tBES on motor cortical excitability up to 30 min post-stimulation. Specifically, MEPs significantly increased after tBES (+) compared to pre-stimulation (p = 0.026) and sham condition (p = 0.025). Conversely, tBES (-) led to a notable decrease in MEPs relative to baseline (p = 0.04) and sham condition (p = 0.048). Although tBES showed a more favorable neuromodulatory effect than tDCS, statistical analysis revealed no significant differences between these two groups (p > 0.05). Additionally, tBES (+) exhibited a significant activation of excitatory neurons, indicated by increased c-Fos expression (p < 0.05), and a reduction in GAD-65 density (p < 0.05). tBES (-) promoted GAD-65 expression (p < 0.05) while inhibiting c-Fos activation (p < 0.05), suggesting the involvement of cortical inhibition with tBES (-). The expression of GFAP showed no significant difference between tBES and sham conditions (p > 0.05), indicating that tBES did not induce neural injury in the stimulated regions.

CONCLUSION: Our study indicates that tBES effectively modulates motor cortical excitability. This research significantly contributes to a better understanding of the neuromodulatory effects of tBES, and could provide valuable evidence for its potential clinical applications in treating neurological disorders.

ABSTRACT

INTRODUCTION: Vitiligo is an acquired depigmenting skin disorder due to the loss of melanocyte function in the epidermis and hair follicles. The pathogenesis of vitiligo is multifactorial, with genetics being a predisposing factor. Previous studies had varying results regarding whether or not polymorphisms of vitamin D receptor (VDR) gene are associated with the risk of vitiligo in specific populations. This study investigated the association between three frequently analyzed VDR gene polymorphisms (ApaI, BsmI, TaqI) and susceptibility to vitiligo in Indonesian population.

METHODS: Thirty-four vitiligo patients and 34 age- and sex-matched healthy subjects aged ≥18 years old were recruited in the Dermatology and Venereology Outpatient Clinic of Dr. Hasan Sadikin General Hospital, Bandung, Indonesia. Genomic deoxyribonucleic acid (DNA) was extracted from the peripheral blood using a DNA isolation kit. VDR gene polymorphisms (ApaI, BsmI, and TaqI) were investigated using the polymerase chain reaction-restriction-fragment length polymorphism method. The differences of genotype distributions and allele frequencies were statistically compared between case and control groups using Chi-square test.

RESULTS: VDR gene polymorphisms were identified in 68 participants, consisting of Aa (n = 14), aa (n = 20), Bb (n = 15), bb (n = 19), and TT (n = 34) genotypes in the case group. In the control group, Aa (n = 6), aa (n = 28), Bb (n = 17), bb (n = 17), and TT (n = 34) genotypes were identified. However, only subjects with ApaI Aa genotype polymorphism had a 3.267-fold increased risk of developing vitiligo.

CONCLUSION: This study showed that ApaI Aa genotype polymorphism of the VDR gene increases the risk of vitiligo in Indonesian population.

ABSTRACT

OBJECTIVES: The increasing number of total hip arthroplasties (THA) has led to increased patient demands and expectations, making it crucial to assess patients’ ability to “forget” their implants in daily life. This study aimed to determine the reliability and validity of a Persian version of the Forgotten Joint Score (P-FJS) in THA patients.

METHODS: The questionnaire was translated bidirectionally with the permission of the questionnaire designer. Data were collected from 2018 to 2020 and included 142 patients who had undergone THA by the same surgeon at least one year ago. Participants completed the FJS questionnaire twice within a one-week interval, and the validity, reliability, and feasibility of the questionnaires were assessed using statistical tests on the HHS and OHS forms completed by all participants.

RESULTS: In 142 patients (52.1% male) with a mean age of 65 ± 0.5 years who answered the questionnaires, P-FJS correlated strongly with OHS and HHS. The internal consistency (α = 0.91) and reproducibility of the questionnaire were excellent. None of the floor and ceiling effects were detected.

CONCLUSION: The P-FJS questionnaire in the THA is considered a legitimate, repeatable, and self-administered survey that can be compared to its English-language counterpart. In addition, it is noteworthy that this version does not show any floor or ceiling effects.

ABSTRACT

BACKGROUND: Growth differentiation factor 15 (GDF15), an inflammatory marker and mediator of adult cancer cachexia, remains largely unexplored in children. GDF15 increases nausea, vomiting, and anorexia in cancer and contributes to malnutrition, with the potential to be a cachexia therapeutic target. No studies have examined GDF15 in children with newly diagnosed cancer. Our pilot study compares GDF15 in children with newly diagnosed cancer to age- and sex-matched controls and correlates levels with anthropometric measurements and quality of life (QOL).

METHODS: Children with newly diagnosed cancer aged 2-21 years were enrolled with serum GDF15 ELISA, anthropometric measures [height, weight, and mid-upper arm circumference (MUAC)], and QOL assessments (using PedsQL™ Core and Gastrointestinal Modules), which were collected at baseline and repeated 3 months later. Serum GDF15 levels were obtained from age- and sex-matched controls for comparison.

RESULTS: A total of 57 participants enrolled (N=30, cancer group; N=27, control group) with a median age of 8.8 years (IQR 5.6-15.9 years). The participants were primarily male (54.4%), white (82.5%), and non-Hispanic (82.5%). Cancer diagnoses included acute lymphoblastic leukemia (N=8), lymphoma (N=8), neuroblastoma (N=5), soft tissue tumors (N=4), acute myeloid leukemia (N=2), and single participants with brain, kidney, and bone tumors. Baseline GDF15 was higher in the cancer cohort compared to the control cohort (median=614.6pg/mL and 320.5pg/mL, respectively; p<0.001). When examining participants with evaluable baseline and 3-month follow-up GDF15 levels (N=18), GDF15 was not statistically different (median=657.1pg/mL and 675.3pg/mL, respectively; p=0.702). A total of 13 of the 30 participants and 21 caregivers completed the PedsQL™ Core and Gastrointestinal symptom modules. QOL scores did not differ significantly at 3-month follow-up compared to baseline, but diarrhea worsened (p=0.017). Median participant response for diarrhea at baseline was 92.9 (IQR=92.9-96.4; N=13), which was significantly better than the follow-up (median=78.6; IQR= 71.4-92.9; p=0.017). There were no correlations between change in height, weight, or MUAC and change in GDF15 levels (p=0.351, 0.920, and 0.269 respectively).

CONCLUSION: GDF15 was elevated in children with cancer at diagnosis compared to controls but did not correlate with anthropometric measurements or QOL. This pilot study will inform future prospective studies to better describe the natural history of GDF15 and its role in cachexia and as a potential therapeutic target.

ABSTRACT

OBJECTIVE: To identify the relationship between patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and their fractional-exhaled nitric oxide (FeNO) levels.

METHODS: Patients diagnosed with AECOPD in the respiratory department of Beijing Chaoyang Hospital from June 2017 to August 2019 were recorded. The demographic data, FeNO value, peripheral blood eosinophil count, number of acute exacerbations in the past year, pulmonary function test, use of inhaled glucocorticoids (ICS) and other data were collected and analyzed. FeNO was measured again three months after discharge, the participants were assessed to determine if the stable period criteria were met.

RESULTS: A total of 214 patients met the requirements of this study. 25ppb for FeNO was used as the cutoff for further analysis. The proportion of males, number of acute exacerbations in the past year, number of ICS users, leukocyte count and eosinophil count in the high FeNO-level group was significantly higher than that in the low-level group (P < 0.05). The results showed that the number of acute exacerbations in the past year, number of ICS users, and eosinophil count were statistically significant in the model (P < 0.05). The study also showed that the level of FeNO in the acute exacerbation phase was significantly higher than that in the stable phase. The ROC curve that the area under the curve used by FeNO to predict ICS used is 0.631 (95% CI: 0.526-0.736), and the corresponding P value is 0.022.

CONCLUSION: FeNO is closely related to activated T2 inflammation and eosinophil count in COPD patients. The FeNO levels can be used as an index to evaluate the severity of COPD and predict the recovery of activity after ICS treatment. FeNO can predict the use of ICS and is a beneficial supplement to eosinophils.

ABSTRACT

Metabolic Syndrome (MS) is a rapidly growing medical problem worldwide and is characterized by a cluster of age-related metabolic risk factors. The presence of MS increases the likelihood of developing atherosclerosis and significantly raises the morbidity/mortality rate of acute coronary syndrome (ACS) patients. Early detection of MS is crucial, and biomarkers, particularly blood-based, play a vital role in this process. This cross-sectional study focused on the investigation of certain plasma ceramides (Cer14:0, Cer16:0, Cer18:0, Cer20:0, Cer22:0, and Cer24:1) as potential blood biomarkers for MS due to their previously documented dysregulated function in MS patients. A total of 695 ACS patients were enrolled, with 286 diagnosed with MS (ACS-MS) and 409 without MS (ACS-nonMS) serving as the control group. Plasma ceramide concentrations were measured by LC-MS/MS assay and analyzed through various statistical methods. The results revealed that Cer18:0, Cer20:0, Cer22:0, and Cer24:1 were significantly correlated with the presence of MS risk factors. Upon further examination, Cer18:0 emerged as a promising biomarker for early MS detection and risk stratification, as its plasma concentration showed a significant sensitivity to minor changes in MS risk status in participants. This cross-sectional observational study was a secondary analysis of a multicenter prospective observational cohort study (Chinese Clinical Trial Registry, https://www.who.int/clinical-trials-registry-platform/network/primary-registries/chinese-clinical-trial-registry-(chictr), ChiCTR-2200056697), conducted from April 2021 to August 2022.
