Analysis of the factors influencing moderate to poor performance status in patients with cancer after chemotherapy: a cross-sectional study comparing three models

There are no models for assessing the factors that determine moderate to poor performance status in patients with cancer after chemotherapy. This study investigated the influencing factors and identified the best model for predicting moderate–poor performance status. A convenience sampling method was used. Demographic and clinical data and evaluation results for fatigue, pain, quality of life and Eastern Cooperative Oncology Group status were collected three days after the end of chemotherapy. Decision tree, random forest and logistic regression models were constructed. Ninety-four subjects in the case group had moderate to poor performance status, and 365 subjects in the control group had no or mild activity disorders. The random forest model was the most accurate model. Physical function, total protein, general quality of life within one week before chemotherapy, hemoglobin, pain symptoms and globulin were the main factors. Total protein and hemoglobin levels reflect nutritional status, and globulin levels are an index of liver function. Therefore, physical function, nutritional status, general quality of life and pain symptoms within one week before chemotherapy and liver function can be used to predict moderate–poor performance status. Nurses should pay more attention to patients with poor physical function, poor nutritional status, lower quality of life and pain symptoms after chemotherapy.

ROLE OF QUILTING TECHNIQUE IN REDUCING SEROMA FORMATION AFTER MODIFIED RADICAL MASTECTOMY

Objectives: The objective of the study was to evaluate the efficacy of mastectomy flap quilting sutures in reducing post-modified radical mastectomy seroma formation. Methods: The prospective study was conducted by the Department of Surgery Sardar Patel Medical College and A.G. Hospitals, Bikaner, from December 2021 to December 2022. Fifty control and 50 cases of carcinoma breast in the general surgery department were recruited in the study. Results: The mean age of the patients in the cases group was 51.00±12.93 years and control group was 54.16±13.39 years. Mean drain volume of the patients in the cases group was 489.00±10.54 mL and control group was 586.00±22.67 mL and the drain duration of surgery of the patients in the cases group was 8.30±0.44 days and the control group was 12.60±0.80 days. Two (4.00%) patients in cases group and eight (16.00%) patients in control group seroma formation was present (p<0.05). Conclusion: Flap fixation is a surgical technique that obliterates the dead space in patients undergoing modified radical mastectomy. It appears to reduce the total volume of fluid drained, the development of seroma, and the need for seroma aspirations.

Evaluation of maternal serum thiol and ischemia-modified albumin levels in cases of placenta previa: A case-control study in a tertiary center.

We aim to compare the maternal serum thiol and ischemia-modified albumin (IMA) levels between pregnant women with placenta previa and those with uncomplicated pregnancies and to determine whether changes in these levels were useful in predicting cases of abnormally invasive placenta (AIP). Fifty-five pregnant women diagnosed with placenta previa according to the diagnostic criteria (case group) were compared to 100 women with uncomplicated pregnancies of similar demographic characteristics (control group). The patients with placenta previa were further divided into two subgroups: AIP (n = 20) and placenta previa without invasion (n = 35). The maternal serum native thiol, total thiol, disulfide, and IMA levels of the groups were evaluated. The native thiol, total thiol, and IMA values were significantly lower in the case group than in the control group (p < 0.001). The disulfide values were similar between the study and control groups (p = 0.488). When the AIP and placenta previa without invasion groups were compared, the levels of native thiol, total thiol, disulfide, and IMA were similar (p > 0.05). Maternal serum thiol and IMA levels were lower in placenta previa cases compared to the control group. However, these parameters were not useful in predicting AIP cases.

CT features of abnormally whole-course wide eustachian tubes with microtia and atresia

Objective: To study the clinical and CT features of the abnormal whole-course wide of eustachian tube (AWWET) with microtia and atresia(MA). Methods: The clinical and CT data of 19 patients (20 ears) from January 2017 to December 2021 with AWWET with MA were retrospectively analyzed, including 15 males and 4 females. The age ranged from 5 to 16 years, with an average of 9.5 years. 50 patients with common MA without wide eustachian tube(ET) as a case control group, including 32 males and 18 females.The age ranged from 5 to 16 years, with an average of 9.2 years. 20 patients (40 ears) who had normal ear CT for tinnitus, otalgia as a normal control group, including 12 males and 8 females. The age ranged from 5 to 16 years, with an average of 12.5 years. We measured the dimension and length of the bony portion of the ET, the total length, the angle between the bony portion and the cartilage portion, and the horizontal angle of ET on CT imagings, and compared with 40 normal ears by SPSS 27.0 software. Results: According to the relationship between AWWET and tympanum, patients were divided into the communicated group and the blocked group. A male predominance, left ear predominance, with high incidence of hemifacial microsomia exhibited in both groups. AWWET was presented as a widened lumen on CT. In 11 ears (4 ears in the communicated group, 7 ears in the blocked group), ETs bifurcated, the upper bony tube extended to the sphenoid body, the lower part continued down to cartilaginous ET and opened onto the nasopharynx, with"mastoid-like"pneumatization of the sphenoid body in 6 ears. The middle ear deformity in case group was more serious than MA control group, especially the blocked group. The incidence of otitis media in the communicated group was lower than that in the MA control group, and 4 cases in the blocked group had effusion in the ET. Compaired with normal ear, the bony ET elongated significantly in the AWWET groups, and the whole course of ET was significantly shortened, specially in the blocked group. The angle between the bony ET and the cartilaginous ET was decreased and the horizontal angle of the ET increased in the AWWET groups, the difference was considered to indicate statistical significance(P<0.05). Conclusions: AWWET with MA is rare, a male predominance, left ear predominance, and with high incidence of hemifacial microsomia. The middle ear deformity is more serious than common MA, especially in the blocked group. The incidence of otitis media in the communicated group is significantly lower than that in the common MA, and the blocked group may be accompanied by ET inflammation.

The combined use of anti-peptic agents is associated with an increased risk of osteoporotic fracture: a nationwide case-control study.

Long-term use of acid suppressants such as proton pump inhibitors (PPIs) and histamine 2 receptor antagonist (H2RA) has been associated with the risk of osteoporotic fracture. Acid suppressants and muco-protective agents (MPAs) are often used together as anti-ulcer agents. We evaluated the association between the risk of osteoporotic fracture and the combined use of these anti-peptic agents. A population-based case-control study was conducted by analyzing the Korean National Health Insurance Data from 2014 to 2020. Patients who had been prescribed anti-peptic agents, such as PPI, H2RA, or MPA, were included. Considering the incidence of osteoporotic fractures, the case group (n = 14,704) and control group (n = 58,816) were classified by 1:4 matching based on age and sex. The use of all types of anti-peptic agents was associated with an increased risk of osteoporotic fractures (PPI: hazard osteoratio [HR], 1.31; H2RA: HR, 1.44; and MPA: HR, 1.33; all p < 0.001). Compared to PPI alone, the combined use of "PPI and H2RA" (HR, 1.58; p = 0.010) as well as "PPI, H2RA, and MPA" (HR, 1.71; p = 0.001) was associated with an increased risk of osteoporotic fracture. However, compared with PPI alone, "MPA and PPI or H2RA" was not associated with an increased risk of osteoporotic fracture. This study found that the combined use of "PPI and H2RA" was associated with a higher risk of osteoporotic fractures. In cases where deemed necessary, the physicians may initially consider prescribing the combination use of MPA.

Adjunctive silymarin supplementation and its effects on disease severity, oxidative stress, and inflammation in patients with Alzheimer’s disease

ABSTRACT Background Brain tissue in Alzheimer's patients is exposed to oxidative stress. Silymarin is an adjunct drug that has anti-inflammatory and antioxidant properties. Objective This study aimed to evaluate the effect of silymarin on biomarkers of oxidative stress, inflammation, and disease severity in Alzheimer's patients. Methods This randomized, single-blind clinical trial study was performed on 33 patients with Alzheimer's disease (AD) whose disease was confirmed by DSM-5 criteria and by brain imaging. Patients in the case group received three 250 mg silymarin capsules daily (each containing 150 mg silymarin), as an adjunctive medication in addition to the routine medication regimen. In the placebo group (control), patients received the same amount of placebo. All patients underwent Mini Mental State Exam (MMSE) and a panel of blood tests including malondialdehyde, neopterin, catalase, paraoxonase-1, total oxidative status, and total antioxidant capacity to reevaluate the changes pre/postintervention at the end of the trimester. Results The catalase and MDA serum levels after the adjunctive silymarin treatment decreased significantly (Catalasebefore silymarin = 9.29 ± 7.02 vs Catalaseafter silymarin = 5.32 ± 2.97, p = 0.007 and MDAbefore silymarin = 4.29 ± 1.90 vs MDAafter silymarin = 1.66 ± 0.84, p < 0.001) while MMSE increased notably (MMSEbefore silymarin = 10.39 ± 6.42 vs MMSEafter silymarin = 13.37 ± 6.81, p < 0.001). Conclusion Silymarin can be effective as an adjunct drug and a powerful antioxidant in reducing oxidative stress and improving the course of AD.

The Triglycerides and Glucose Index Is an Independent Risk Factor for Acute Respiratory Distress Syndrome in Patients with COVID-19.

Introduction: Although it has been observed that the triglycerides and glucose (TyG) index, a biomarker of insulin resistance, is associated with severity and morbidity by COVID-19, evidence is still scarce. Therefore, the objective of this study was to determine whether the TyG index is associated with both the degree of severity and mortality by acute respiratory distress syndrome (ARDS) in patients with COVID-19. Methods: Men and women aged 20 years or more with diagnosis of COVID-19 were included in a case-control study. Exclusion criteria were pregnancy, cancer, autoimmune diseases, autoimmune treatment, and incomplete data. Patients with severe COVID-19 ARDS were allocated into the case group, and those with mild or moderate COVID-19 ARDS in the control group. COVID-19 was defined by a positive reverse transcriptase-polymerase chain reaction test for SARS-CoV-2, and ARDS was defined according to the Berlin criteria. Results: A total of 206 patients were included and allocated into the case (n = 103) and control (n = 103) groups. The logistic regression analysis adjusted by age, sex, and body mass index showed that the TyG index is significantly associated with moderate [odds ratio (OR) = 6.0; 95% confidence interval (CI): 1.1-30.6] and severe (OR = 9.5; 95% CI: 2.4-37.5) COVID-19 ARDS, and death (OR = 10.1; 95% CI: 2.2-46.5). Conclusion: The results of our study show a significant and independent association of the TyG index with ARDS and mortality in patients with COVID-19.

Impact of lifestyle and clinical factors on the prognosis of tennis elbow

Tennis elbow (lateral epicondylitis) typically responds well to conservative treatment, and few patients require surgical intervention. This study aimed to investigate the influence of lifestyle and clinical factors on the prognosis of tennis elbow. This prospective, multicenter, nested case–control study included patients diagnosed with lateral epicondylitis after excluding other conditions. Patients who required surgery because of inadequate improvement after 6 months of conservative treatment were defined as the case group; the remaining patients constituted the control group. Propensity score matching was performed to eliminate baseline differences. Univariate and multivariate analyses were performed using logistic regression. This study included 265 patients (53 in the case group, 212 in the control group). Multivariate analysis revealed that smoking, alcohol consumption, and frequent physical exercise were independent risk factors for surgical intervention, whereas combined treatment with oral nonsteroidal anti-inflammatory drugs (NSAIDs) and local corticosteroid injections was a protective factor against surgery. Subgroup analysis showed that heavy drinkers had a 3.74-fold higher risk of requiring surgical treatment within 1 year than occasional drinkers. Smoking and alcohol consumption were associated with non-operative treatment failure in patients with lateral epicondylitis. Combining oral NSAIDs and corticosteroid injections is a favorable conservative treatment option.

Computer-Aided Discrimination of Glaucoma Patients from Healthy Subjects Using the RETeval Portable Device.

Glaucoma is a chronic, progressive eye disease affecting the optic nerve, which may cause visual damage and blindness. In this study, we present a machine-learning investigation to classify patients with glaucoma (case group) with respect to normal participants (control group). We examined 172 eyes at the Ophthalmology Clinic of the "Elpis" General Hospital of Athens between October 2022 and September 2023. In addition, we investigated the glaucoma classification in terms of the following: (a) eye selection and (b) gender. Our methodology was based on the features extracted via two diagnostic optical systems: (i) conventional optical coherence tomography (OCT) and (ii) a modern RETeval portable device. The machine-learning approach comprised three different classifiers: the Bayesian, the Probabilistic Neural Network (PNN), and Support Vectors Machines (SVMs). For all cases examined, classification accuracy was found to be significantly higher when using the RETeval device with respect to the OCT system, as follows: 14.7% for all participants, 13.4% and 29.3% for eye selection (right and left, respectively), and 25.6% and 22.6% for gender (male and female, respectively). The most efficient classifier was found to be the SVM compared to the PNN and Bayesian classifiers. In summary, all aforementioned comparisons demonstrate that the RETeval device has the advantage over the OCT system for the classification of glaucoma patients by using the machine-learning approach.

Genome-wide association study implicates the role of TBXAS1 in the pathogenesis of depressive symptoms among the Korean population

Although depression is an emerging disorder affecting many people worldwide, most genetic studies have been performed in European descent populations. Herein, a genome-wide association study (GWAS) was conducted in Korean population to elucidate the genomic loci associated with depressive symptoms. Two independent cohorts were used as discovery datasets, which consisted of 6474 (1484 cases and 4990 controls) and 1654 (557 cases and 1097 controls) Korean participants, respectively. The participants were divided into case and control groups based on the Beck Depression Inventory (BDI). Meta-analysis using the two cohorts revealed that rs6945590 was significantly associated with the risk of depressive symptoms [P = 2.83 × 10−8; odds ratio (OR) = 1.23; 95% confidence interval (CI): 1.15–1.33]. This association was validated in other independent cohorts which were another Korean cohort (258 cases and 1757 controls) and the East Asian study of the Psychiatric Genomics Consortium (PGC) (12,455 cases and 85,548 controls). The predicted expression levels of thromboxane A synthase 1 gene (TBXAS1), which encodes the enzyme thromboxane A synthase 1 and participates in the arachidonic acid (AA) cascade, was significantly decreased in the whole blood tissues of the participants with depressive symptoms. Furthermore, Mendelian randomization (MR) analysis showed a causal association between TBXAS1 expression and the risk of depressive symptoms. In conclusion, as the number of risk alleles (A) of rs6945590 increased, TBXAS1 expression decreased, which subsequently caused an increase in the risk of depressive symptoms.

Investigation of Oxidative Stress and Antioxidant Pathways in Nasal Polyp Tissue: Peroxynitrite and Malondialdehyde Compared to NF-E2-related factor 2, Kelch-like ECH-associated protein one and Glycogen Synthase Kinase-3ß

Objective: Nasal polyps are benign mucosal lesions with multifactorial causes that grow into the nasal cavity and are associated with inflammation. This study aims to investigate whether Nrf2, Keap1, GSK-3ß, Peroxynitrite, and malondialdehyde may be used as biochemical markers to determine the relationship between oxidative stress and nasal polyps. The goal is to explore the etiology of nasal polyps and contribute to the literature for a better understanding of the inflammatory pathophysiology of nasal polyps, ultimately leading to the development of new therapeutic approaches. Materials and Methods: A total of 94 patients aged between 12 and 65 years who underwent a surgical operation for polyps (n = 49, case group) and septoplasty (n=45, controls) between February and September 2022 at the Department of Otorhinolaryngology, Faculty of Medicine, Gaziantep University were included in the study. Tissues taken from the polyp and the inferior turbinate in the case and control groups, respectively, were homogenized at the biochemistry laboratory and investigated using the ELISA method to compare the Nrf-2, Keap1, GSK-3ß, malondialdehyde, and peroxynitrite levels. Results: Consistent with the study hypothesis, Nrf2 levels were lower, and Keap1 levels were higher in the case group, although the difference was not statistically significant. Although studies have reported increased levels of GSK-3β in chronic rhinosinusitis, they were statistically lower in polyps. This may be associated with the complexity of the GSK-3β network or the adequacy of Keap1 alone for Nrf2 inhibition. Peroxynitrite and malondialdehyde (MDA) levels are indicators of oxidative stress. Conclusion: Nrf2, Keap1, GSK-3ß, MDA, and Peroxynitritetrite may be involved in the aetiology of nasal polyps based on the study's results. Keap1 and GSK-3ß, Nrf2 and Nrf2 module, actors which regulate oxidative stress, played a role in the pathophysiology of nasal polyps in combination with Peroxynitritetrite and malondialdehyde, according to the study findings. Potential treatments for nasal polyps are better understood through more extensive and well-matched studies.

Methods and functions of non-suicidal self-injury in an adolescent and young adult clinical sample

BackgroundNon-suicidal self-injury (NSSI) is an emerging critical medical condition among adolescents and young adults worldwide. They use different methods for expressing their emotional needs. The aim of this study was to identify the methods of NSSI used by adolescents and young adults who presented with different psychiatric disorders, and their utilized functions.Subjects/materials and methodsA case–control study was done on 100 late adolescent and young adult patients who attended Suez Canal University with psychiatric disorders. Sociodemographic data was obtained then they were assessed by the Mini-International Neuropsychiatric Interview and the Brief Non-suicidal Self-Injury Assessment Tool.ResultsAmong the case group, 54% used scratching for self-harm while 36% used cutting. The most common body areas were hands (44%) and arms (42%). Eighty percent of the case group endorsed non-suicidal self-harm for dealing with anger, while 78% to cope with uncomfortable feelings and 72% to relieve stress with no statistically significant difference between males or females, nor among psychiatric comorbidities.ConclusionThe most common method of NSSI was scratching and it was followed by cutting and banging. The most common body areas were hands and arms. Patients endorsed NSSI for various motives and several functions. However, Items on the automatic negative reinforcement scales were the most common functions, especially when dealing with anger.

Effect of DIO2 Gene Polymorphism on Thyroid Hormone Levels and Its Correlation with the Severity of Schizophrenia in a Pakistani Population.

Low levels of triiodothyronine (T3) in the brain lead to increased dopamine receptor sensitivity, potentially resulting in schizophrenia. Iodothyronine deiodinase 2 (DIO2) is the only enzyme which converts tetraiodothyronine (T4) to T3 in the brain. DIO2 polymorphism of rs225014 results in the expression of non-functioning DIO2. Therefore, this study aimed to investigate the association of rs255014 with schizophrenia and its impact on thyroid hormone levels. This study included 150 schizophrenia cases and 150 controls. DNA was extracted from blood and subjected to PCR and amplicon sequencing. Serum thyroid profiles were determined using chemiluminescent magnetic microparticle immunoassay. Statistical analyses involved independent sample t-tests, Chi-square, and Pearson's correlation tests. The results revealed a higher frequency of the reference genotype (TT) in controls compared to cases (p < 0.05). However, rs225014 did not influence serum thyroid levels or the severity of schizophrenia (p > 0.05). Interestingly, control subjects exhibited significantly higher T3 levels (p < 0.001) than cases. Regardless of the genotype (TT or CC), the control group had higher mean T3 levels than the corresponding case group (p < 0.05). In conclusion, rs225014 is associated with schizophrenia and has no effect on serum thyroid hormone levels.

Assessment of Platelet Indices as Biomarker for Neonatal Sepsis

Introduction: There is a need to increase the diagnostic capability of the traditional septic screen by adding additional markers. Platelet indices are one such marker that is readily available in routine hemogram reports. Materials and Methods: In this cross-sectional study, all newborn babies were recruited who had signs or symptoms of sepsis or had high-risk factors. Those who had clinical sepsis with positive cultures and/or a positive sepsis screen were classified under group “cases” ( n = 174), whereas all neonates suspected to have sepsis but who had a negative blood culture and a negative sepsis screen were classified under group “control” ( n = 126). Blood culture, sepsis screen, and platelet indices [platelet count, mean platelet volume (MPV), and platelet distribution width (PDW)] were performed on all babies. Babies with congenital or acquired causes of platelet abnormalities (including medication use by mothers with antiplatelet activity) were excluded from this study. Results: In this study, a total of 300 newborn babies were recruited for final analyses. Overall culture positivity was 38%. The mean platelet count was lower in the cases group ( P &lt; 0.001). MPV and PDW were higher in septic babies with statistically significant differences ( P &lt; 0.0001 and P = 0.012, respectively). Thrombocytopenia was the most sensitive marker (85.60%). However, it had low specificity (28.2%). On combining all three platelet markers, specificity increased to 48.4% (with a sensitivity of 64.5%) in detecting babies with neonatal sepsis. The sensitivity of the septic screen alone was 58% (with a specificity of 32.62%). When combining the sepsis screen and platelet indices, the specificity for the diagnosis of neonatal sepsis increased to 62.6%. On receiver operator curve analyses, thrombocytopenia had the highest area under the curve (0.692), followed by MPV (0.644). Conclusion: Platelet indices may be used as sensitive markers in combination with traditional sepsis screening to make an early diagnosis of neonatal sepsis.

Ex vivo observation of Pythium insidiosum-antigen treated neutrophils on three Pythium insidiosum strains isolated from vascular pythiosis patients

ABSTRACT The mechanisms of Pythium insidiosum-antigen (PIA) immunotherapy activating a patient’s immune system are unknown. We evaluated the interleukin-8 (IL-8) serum levels during P. insidiosum infection and after vaccination with PIA in vascular pythiosis cases. Furthermore, we studied the anti-P. insidiosum activity of neutrophils stimulated with various concentrations of PIA ex vivo in 3 strains of P. insidiosum isolated from vascular pythiosis patients. IL-8 serum levels were evaluated using the ELISA technique. We assessed the effect of PIA-stimulated neutrophils on the viability of zoospores using MTT assay, visualized neutrophil extracellular trap (NET) formation via microscopy, and measured the levels of double-stranded DNA (dsDNA) using PicoGreen dsDNA quantitation assay in 3 strains of P. insidiosum isolated from vascular pythiosis patients. Serum levels of IL-8 gradually lowered from the early to the end phases of vaccination with PIA among the surviving group of vascular pythiosis cases. Neutrophils stimulated with 0.01 µg/ml PIA reduced zoospore viability significantly compared to PIA-unstimulated neutrophils for strain 1 and strain 3 (p < .05). Neutrophils stimulated with 0.01, 0.1, 1, and 10 µg/ml PIA exhibited significantly lower zoospore viability than PIA-unstimulated neutrophils for strain 2 (p < .05). IL-8 can be used as a biomarker for monitoring vascular pythiosis cases treated with the PIA vaccine. Also, anti-P. insidiosum activity of PIA-stimulated neutrophils was probably due to the disruption of cellular activity in zoospores rather than the mechanisms based on the formation of NETs.

Selenium Concentrations in Patients with Depression: A Case-Control Study

Background: Evidence suggests that dietary micronutrients may be associated with depression. The role of selenium as a risk or protective factor for depression was contradictory. Therefore, this study aimed to investigate the association between serum selenium concentrations and depression. Methods: This case-control study was conducted from 2018 to 2020 in Shahrekord, Iran. The case and control groups included patients with or without depression, respectively. Seventy-two participants were selected using the conventional method. In addition to recording demographic variables, the blood selenium concentration of the participants was measured. Results: There was no difference between case and control groups in terms of mean levels of blood selenium (P&gt;0.05). Results showed that there was no statistically significant interaction between the effects of gender and group (P=0.51), age and group (P=0.13), Body mass index (BMI) and group (P=0.52) on blood selenium concentrations. However, females had significantly more selenium concentrations than males in both groups (P=0.005). Conclusion: Despite some confirming evidence for the association of depression and blood selenium concentration, this study did not show such a relationship. However, blood selenium concentration was higher in women than men in both groups.

Association between Genetic Variants Linked to Premature Ovarian Insufficiency and Inflammatory Markers: A Cross-Sectional Study.

Premature menopause (PM) is the cessation of ovarian function before age 40. PM women are more likely to have cardiovascular diseases (CVDs), diabetes, and mental disorders. This is the first study that assessed the association of single nucleotide polymorphisms (SNPs) with anti-heat shock protein 27 (Hsp27), High-sensitivity C-reactive protein (hs- CRP), and PM and serum pro-oxidant-antioxidant balance (PAB), as putative risk factors for CVDs. We aimed to explore the association of oxidative stress markers with eight different SNPs shown to be related to premature menopause. In this cross-sectional research, we included 183 healthy women and 117 premature menopausal women. We determined baseline characteristics for all participants and measured serum hs-CRP, anti-HSP-27 antibody titer, and PAB levels using the established methods. Genotyping for eight SNPs was done using the tetra amplification refractory mutation system polymerase chain reaction (Tetra-ARMS PCR) and allele-specific oligonucleotide PCR (ASO-PCR) methods. We found a significant difference between mean serum PAB levels and the genetic variant of rs16991615 (P=0.03). ANCOVA showed a significant effect of the genotypes rs4806660 and rs10183486 on hs-CRP serum levels in the case and control groups, respectively (P=0.04 and P=0.007). ANCOVA also showed an association between rs244715 genotypes and anti-hsp27 serum levels in the case group (P=0.02). There was a significant effect of the genotypes of rs451417 on the serum hs-CRP level in the control group (P=0.03). There was a significant association of the genetic variants related to PM with oxidative stress and inflammatory markers (serum PAB, anti-hsp27 antibody, and hs-CRP). Accordingly, this seems to be an effective approach to predicting susceptible subjects for cardiovascular and mental disorders as well as various cancers.

Investigating Ovulation Induction Outcomes in Patients with Decreased Ovarian Reserve Treated with Double Stimulation during The Follicular and Luteal Phases Compared to The Conventional Antagonist Cycle: A Randomized Clinical Trial.

It is difficult to obtain healthy oocytes in poor ovarian responders with conventional treatment methods. Thus, the need to investigate new methods is essential. This study aims to investigate ovulation induction outcomes in patients with decreased ovarian reserve (DOR) in two groups treated with double stimulation (DuoStim) during the follicular and luteal phases in comparison with the antagonist cycle. This was a randomised clinical trial that enrolled the patients with reduced ovarian reserve. The patients referred for in vitro fertilization (IVF) at Molud Infertility Clinic, Ali Ebn Abitalib (AS) Hospital, Zahedan, Iran from 2020 to 2021. Participants were randomly divided into two groups, those who underwent treatment with DuoStim during the follicular and luteal phase (case group) and those who received the conventional antagonist cycle (control group). The mean number of metaphase II (MII) eggs was 7.7 ± 3.1 in the case group and 6.1 ± 3.9 in the control group (P=0.063). The mean total number of retrieved eggs in the case group was 9.2 ± 3.7 and in the control group, it was 6.9 ± 4.4 (P=0.023). The mean number of embryos obtained in the case group was 6.5 ± 3.9; in the control group, it was 4.7 ± 2.8 (P=0.016). The DuoStim method can effectively play a role in increasing the total number of retrieved eggs and embryos (registration number: IRCT20120817010617N8).

The impact of BMI on breast cancer - an updated systematic review and meta-analysis.

Breast cancer is the most frequent form of cancer in women all over the world. It is the main cause of cancer death and the most often diagnosed cancer in women in 140 of the world's 184 countries. The link between breast cancer risk and body mass index (BMI) has gotten increasing attention in recent years, although the results are still debatable. Therefore, the current systematic review and meta-analysis evaluate the impact of BMI on breast cancer. The current study was carried out as a systematic review and meta-analysis, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We systematically searched Cochrane, Google Scholar, PubMed, EMBASE and Scopus databases to identify eligible articles impact of BMI on breast cancer with the appropriate Medical Subject Headings (MeSH). The Newcastle-Ottawa checklist was used for the risk of assessment for the included studies. Meta-analysis was performed using Review Manager 5.3 software. Forty-six studies were included in the current review, which met the selection criteria of the current review. Among included 46 studies in this review, 50% (n = 23) of the studies found the HER2 type of breast cancer followed by triple-negative and HR-positive. The obesity was significantly higher in the case group compared with the control group (P < .001). Heterogeneity between the 14 studies is medium (I2 = 72%). In this review, there was no significant relation between overweight and breast cancer in women (P > .05). Heterogenecity between the 14 studies is medium (I2 = 89%). However, after removing the publication bias a significant relation between overweightness and breast cancer in women (P = .0005) was observed. Obese breast cancer patients are a specific type of patient. They are more likely to develop cancer. Their need to surgery and radiation may cause greater difficulties. Obesity and overweight in women greatly increase the risk of breast cancer, according to the findings of the current meta-analysis. To confirm these findings and understand the pathogenic pathways, more research is required.

Topic evolution before fall incidents in new fallers through natural language processing of general practitioners' clinical notes.

Falls involve dynamic risk factors that change over time, but most studies on fall-risk factors are cross-sectional and do not capture this temporal aspect. The longitudinal clinical notes within electronic health records (EHR) provide an opportunity to analyse fall risk factor trajectories through Natural Language Processing techniques, specifically dynamic topic modelling (DTM). This study aims to uncover fall-related topics for new fallers and track their evolving trends leading up to falls. This case-cohort study utilised primary care EHR data covering information on older adults between 2016 and 2019. Cases were individuals who fell in 2019 but had no falls in the preceding three years (2016-18). The control group was randomly sampled individuals, with similar size to the cases group, who did not endure falls during the whole study follow-up period. We applied DTM on the clinical notes collected between 2016 and 2018. We compared the trend lines of the case and control groups using the slopes, which indicate direction and steepness of the change over time. A total of 2,384 fallers (cases) and an equal number of controls were included. We identified 25 topics that showed significant differences in trends between the case and control groups. Topics such as medications, renal care, family caregivers, hospital admission/discharge and referral/streamlining diagnostic pathways exhibited a consistent increase in steepness over time within the cases group before the occurrence of falls. Early recognition of health conditions demanding care is crucial for applying proactive and comprehensive multifactorial assessments that address underlying causes, ultimately reducing falls and fall-related injuries.
