Abstract
Background Recent years have seen the emergence of disease-modifying therapies in multiple sclerosis (MS), such as anti-cluster of differentiation 20 (anti-CD20) monoclonal antibodies, aiming to modulate the immune response and effectively manage MS. However, the relationship between anti-CD20 treatments and immunoglobulin G (IgG) levels, particularly the development of hypogammaglobulinemia and subsequent infection risks, remains a subject of scientific interest and variability. We aimed to investigate the intricate connection between anti-CD20 MS treatments, changes in IgG levels, and the associated risk of hypogammaglobulinemia and subsequent infections. Method PubMed, Scopus, Embase, Cochrane, and Web of Science databases have been searched for relevant studies. The "R" software utilized to analyze the occurrence of hypogammaglobulinemia, infections and mean differences in IgG levels pre- and post-treatment. The subgrouping analyses were done based on drug type and treatment duration. The assessment of heterogeneity utilized the I2 and chi-squared tests, applying the random effect model. Results Thirty-nine articles fulfilled our inclusion criteria and were included in our review which included a total of 20,501 MS patients. The overall prevalence rate of hypogammaglobulinemia was found to be 11% (95% CI: 0.08 to 0.15). Subgroup analysis based on drug type revealed varying prevalence rates, with rituximab showing the highest at 18%. Subgroup analysis based on drug usage duration revealed that the highest proportion of hypogammaglobulinemia occurred in individuals taking the drugs for 1 year or less (19%). The prevalence of infections in MS patients with a focus on different infection types stratified by the MS drug used revealed that pulmonary infections were the most prevalent (9%) followed by urinary tract infections (6%), gastrointestinal infections (2%), and skin and mucous membrane infections (2%). Additionally, a significant decrease in mean IgG levels after treatment compared to before treatment, with a mean difference of 0.57 (95% CI: 0.22 to 0.93). Conclusion This study provides a comprehensive analysis of the impact of anti-CD20 drugs on serum IgG levels in MS patients, exploring the prevalence of hypogammaglobulinemia, based on different drug types, treatment durations, and infection patterns. The identified rates and patterns offer a foundation for clinicians to consider in their risk-benefit.

Abstract
RATIONALE AND OBJECTIVES Determining dry weight is crucial for optimizing hemodialysis, influencing efficacy, cardiovascular outcomes, and overall survival. Traditional clinical assessment methods for dry weight, relying on factors such as blood pressure and edema, frequently lack reliability. Lung ultrasound stands out as a promising tool for assessing volume status, given its non-invasiveness and reproducibility. This study aims to explore the role of Lung ultrasound in evaluating the impact of hemodialysis and ultrafiltration on extravascular lung water, with a specific focus on changes in B-lines post-hemodialysis compared to pre-hemodialysis. MATERIALS AND METHODS The research encompassed searches across PubMed, WOS, and Scopus databases for studies related to lung ultrasound and hemodialysis. A meta-analysis was then performed to determine the mean differences in various parameters before compared to after, hemodialysis, including the number of B-lines, indexed end-inspiratory and end-expiratory inferior vena cava diameters, inferior vena cava collapsibility index, weight, blood pressure, and serum levels of NT-pro-BNP. RESULTS Our meta-analysis, included 33 studies with 2301 hemodialysis patients, revealed a significant decrease in the number of B-lines post-hemodialysis (mean difference = 8.30, 95% CI [3.55 to 13.05]). Furthermore, there was a noteworthy reduction in inspiratory and expiratory inferior vena cava diameters post-hemodialysis (mean difference = 2.32, 95% CI [0.31 to 4.33]; mean difference = 4.05, 95% CI [2.44 to 5.65], respectively). Additionally, a significant positive correlation was observed between B-lines and the maximum inferior vena cava diameter both pre- and post-hemodialysis (correlation coefficient = 0.39; correlation coefficient = 0.32, respectively). CONCLUSION These findings indicate the effectiveness of lung ultrasound in detection of volume overload and assessment of response to ultrafiltration in hemodialysis patients.

Abstract
OBJECTIVE This study aims to explore the multifaceted factors influencing anxiety levels in oncology patients, with a specific focus on the impact of earthquakes in the context of Turkey. Our objective is to identify and understand sociodemographic, clinical, and lifestyle determinants associated with anxiety in cancer patients, examining how traumatic events, such as earthquakes, contribute to heightened anxiety levels. MATERIALS AND METHODS A cross-sectional study was conducted, involving 149 oncology patients undergoing treatment at two prominent oncology centers in Turkey. The study collected comprehensive sociodemographic information and assessed anxiety levels using the Beck Anxiety Scale. The dataset was analyzed using SPSS 20.0 (IBM Corp., Armonk, NY), employing a range of statistical methods including descriptive statistics, independent t-tests, Mann-Whitney U tests, and Chi-square tests. RESULTS The findings underscore several factors significantly linked to anxiety levels in oncology patients. Notably, women, younger patients (age <65), and individuals with specific cancer types exhibited higher anxiety levels. Elevated anxiety was also associated with compromised physical functioning, experiences of earthquakes, irregular sleep patterns, dietary habits, fatigue, and the use of antidepressants. CONCLUSION This study provides insights into the intricate interplay of factors influencing anxiety levels in oncology patients. Understanding these determinants is paramount for tailoring effective psychosocial support and interventions. The results underscore the need for holistic approaches to enhance the overall quality of life for cancer patients. Gender, age, cancer type, physical well-being, lifestyle choices, and exposure to trauma all play pivotal roles in influencing anxiety levels. These findings hold practical implications for the development and implementation of targeted psychosocial interventions aimed at improving anxiety management and overall well-being for oncology patients.

Abstract
OBJECTIVE Breast cancer is common among women aged 65 and over. There is a significant lack of evidence regarding the treatment of breast cancer in patients in this age group due to the rare inclusion of these patients in clinical studies. However, it is known that survival in elderly patients with breast cancer is significantly reduced in those not receiving standard therapy. Several factors, including patients' comorbidities, performance status, life expectancy, and tumor pathological and molecular characteristics, can affect the outcomes of treatment. In this study, we aimed to update the knowledge in this field by assessing these factors among the geriatric population in our multicenter dataset. METHODS This retrospective study analyzed data from 335 breast cancer patients aged 65 and over who received adjuvant radiotherapy at five oncology centers (Kartal Dr. Lutfi Kirdar Training and Research Hospital, Istanbul, Meram Medical Faculty - Necmettin Erbakan University, Konya, Prof. Dr. Cemil Tascioglu City Hospital, Istanbul, Umraniye Training and Research Hospital, Istanbul, and Istanbul Oncology Hospital, Istanbul) between May 2010 and September 2022. Demographic, clinical, and pathological data were collected, including age, gender, clinical symptoms, tumor characteristics, treatment approaches, and outcomes. Statistical analyses, including descriptive statistics, Kaplan-Meier analysis, log-rank test, and Cox regression analysis, were performed using IBM SPSS Statistics for Windows, Version 22 (Released 2013; IBM Corp., Armonk, New York, United States), with a significance level of p < 0.05. RESULTS The tumor characteristics and survival time of 335 breast cancer patients were examined. In the results, performance status, T stage, and perineural invasion were found to be factors affecting the survival of elderly breast cancer patients. In multivariate analysis, it was seen that performance status played an important role as an independent prognostic factor. CONCLUSION The treatment of breast cancer in the geriatric age group necessitates a personalized approach, taking into account the patient's overall health status, life expectancy, and comorbidities.

Abstract
This review assesses the antiviral potential of melatonin through comprehensive analysis of studies across human subjects, animal models, cell cultures, and in-silico simulations. The search strategy targeted relevant research until 22 June 2023, resulting in 20 primary studies after screening and deduplication. The findings highlight strong evidence supporting antiviral properties of melatonin. In silico studies identify melatonin as a candidate against SARS-CoV-2, reducing cytokine storm-related respiratory responses. Cell culture experiments reveal its multifaceted effects on different viruses including respiratory syncytial virus, anti-dengue virus, transmissible gastroenteritis virus, and encephalomyocarditis virus. Animal studies show melatonin reduces mortality and viral replication in various infections such as Venezuelan equine encephalomyelitis and COVID-19. Clinical trials show how it could be evaluated, but with no conclusive evidence of efficacy and safety so far from large, double-blind placebo-controlled trials. These insights showcase the potential of melatonin as a versatile antiviral agent with immunomodulatory, antioxidant, anti-inflammatory and antiviral properties. In summary, our review highlights melatonin's promising antiviral properties across diverse settings. Melatonin's immunomodulatory and antiviral potential makes it a compelling candidate for further investigation, emphasising the need for rigorous clinical trials to establish its safety and efficacy against viral infections.

Abstract
The fear of death associated with cancer and the side effects of its treatments can have a detrimental psychological impact on breast cancer patients. Early detection and support services play a crucial role in alleviating the expected symptoms of depression, anxiety, and sexual dysfunction. The objective of our study is to assess the levels of depression, anxiety, and sexual dysfunction in breast cancer patients, as well as identify the factors that influence these conditions. The study involved 329 voluntarily participating breast cancer patients who had undergone surgery and were in the follow-up stage. Data were collected from 8 different centers after obtaining ethical approval. The assessment utilized tools such as the Sociodemographic Information Form, Beck Depression and Anxiety Scale, and Arizona Sexual Experiences Scale. Data analysis was performed using SPSS 20. The study included 329 breast cancer patients in the follow-up stage post-surgery. Their average age was 52.7 years (range: 27-83). Results indicated that 33.1% experienced moderate to severe depression, 18.2% reported severe anxiety, and 82.7% scored above 11 on the sexual scale. Factors linked to higher scores were mastectomy, surgical dissatisfaction, insufficient information on sexual side effects, and comorbidities like smoking and diabetes. The study emphasizes the importance of closely monitoring anxiety, depression levels, and sexual side effects in breast cancer treatment. It underscores the need to focus not only on reducing mortality rates but also on supporting patients' psychological and sexual well-being, ultimately improving their overall quality of life.

Abstract
BACKGROUND AND AIM This study aimed to determine treatment outcomes and factors affecting prognosis in patients diagnosed with anal canal cancer who received radical radiotherapy (RT) or radiotherapy combined with chemotherapy (CT-RT) in radiation oncology centers in Turkey and compare the results with literature. MATERIAL AND METHOD The study included 193 patients with anal canal cancer reported between 1995 and 2019, of which 162 had complete data. The study was conducted in 11 radiation oncology centers, and a joint database was shared among them. Patients received radiotherapy doses of 45 Gy to 60 Gy. Data analysis was done using SPSS for Windows version 20. RESULTS Median follow-up was 48.51 months (2-214). All patients received radiotherapy, and 140 (86.4%) received concurrent chemotherapy. Radiotherapy doses of 50.4 Gy to 60 Gy were administered to 74 patients (45.7%) using 2-dimensional-3-dimensional (2D-3D) conformal therapy and 70 patients (43.2%) using intensity modulated radiotherapy technique (IMRT). Acute phase hematologic toxicity was observed in 62 patients (38.3%), and nonhematologic toxicity in 123 patients (75.9%). The 5-year overall survival (OS) rate was 75.1% and disease-specific survival (DSS) rate was 76.4%. OS without colostomy was achieved in 79,8 % at 5 years, and complete response in 112 patients (69.1%). OS rate was significantly higher in 142 patients with positive response (P < .000) and 112 with complete response (P < .000). Anemia (P < .002), local progression, and systemic progression (P < .000) resulted in lower OS (P < .002). In univariate analysis, factors affecting OS rate were: gender, age, stage, lymph node status, T stage, RT treatment duration, and treatment planning with PET fusion, which were found to be statistically significant. Completing radiotherapy in less than 45 days, concurrent chemotherapy, and continued administration of mitomycin and 5 FU as chemotherapy had a significant positive effect on overall survival. OS rate was higher in patients receiving RT dose of 58 Gy or less and undergoing IMRT planning in radiotherapy. IMRT was associated with lower acute and late side effects. CONCLUSION Radiochemotherapy is the primary treatment for anal canal cancer and advanced radiotherapy techniques may increase survival by reducing side effects and improving treatment continuation. Higher treatment doses require further investigation. The efficacy of treatment can be improved by including patients treated with modern radiotherapy techniques in multicenter prospective studies using new and more effective chemotherapy and immunotherapy agents.

Abstract
Randomized studies evaluating hypofractionation and conventional fractionation radiotherapy treatments (RT) in patients with breast cancer have shown that hypofractionation achieves similar results to conventional fractionation in terms of survival and local control rates. It has also been shown that their long-term toxicities are similar. This study aimed to evaluate the effects of hypofractionated radiotherapy (H-RT) and conventional radiotherapy (C-RT) on lung toxicity and identify factors affecting this toxicity in patients with breast cancer. The study included 118 patients who underwent adjuvant RT following breast-conserving surgery (BCS). Out of these, 63 patients were assigned to receive C-RT, while the remaining 55 were assigned to receive H-RT. To clarify, we treated 63 patients with C-RT and 55 patients with H-RT. 60 patients were treated using 3-dimensional conformal radiotherapy (3DCRT) and 58 patients were treated using intensity modulated radiotherapy (IMRT). The patients were evaluated weekly for toxicity during radiotherapy (RT) treatment and were called every 3 months for routine controls after the treatment. The first control was performed 1 month after the treatment. Statistical analysis was performed using the SPSS20 program, and a P value of <.005 was considered statistically significant. The study found that the median age of the participants was 54.9 years and tomographic findings were observed in 70 patients. Radiological findings were detected at a median of 5 months after RT. The mean lung dose (MLD) on the treated breast side (referred to as ipsilateral lung or OAR) was 10.4 Gy for the entire group. Among patients who received 18 MV energy in RT, those with an area volume (V20) of the lung on the treated breast side >18.5%, those with a mean dose of the treated breast side lung (ipsilateral lung) >10.5 Gy, and those who received concurrent hormone therapy had significantly more tomographic findings. However, patients treated with YART had fewer tomographic findings. No symptomatic patients were observed during the follow-up period. Our findings show that the risk of lung toxicity is similar with H-RT and C-RT, and H-RT can be considered an effective and safe treatment option for breast cancer. The key factors affecting the development of lung toxicity were found to be the type of RT energy used, RT to the side breast, volume receiving 20 Gy in the side lung, side lung mean dose, and simultaneous hormonal therapy.

Abstract
The baculovirus expression vector systems (BEVS) have been widely used for the recombinant production of proteins in insect cells and with high insert capacity. However, baculovirus does not replicate in mammalian cells; thus, the BacMam system, a heterogenous expression system that can infect certain mammalian cells, was developed. Since then, the BacMam system has enabled transgene expression via mammalian-specific promoters in human cells, and later, the MultiBacMam system enabled multi-protein expression in mammalian cells. In this review, we will cover the continual development of the BEVS in combination with CRPISPR-Cas technologies to drive genome-editing in mammalian cells. Additionally, we highlight the use of CRISPR-Cas in glycoengineering to potentially produce a new class of glycoprotein medicines in insect cells. Moreover, we anticipate CRISPR-Cas9 to play a crucial role in the development of protein expression systems, gene therapy, and advancing genome engineering applications in the future.

Factors Affecting the Willingness to Undertake Premarital Screening Test Among Prospective Marital Individuals. SAGE Open Nurs 2022; 8:23779608221078156.

Abstract
Introduction Awareness toward premarital screening test and its influence on preventing
high risk marriages has become a concern to the health care system in Oman.
This is due to the increased rates of inherited diseases and genetic
disorders among the Omani population secondary to consanguineous
marriages. Objectives This cross-sectional study aims to describe the utilization of premarital
screening tests of selected university study participants as future
prospective couples. Methods The study included 400 Omani study participants from different majors at a
national governmental university that receives students from all over the
country. Data was collected using a self-administered questionnaire. Results Out of the 400 study participants 193 [48.3%] were females and 195 [48.8%]
were males, and 380 [95%] were unmarried and 19 [4.8%] were married.
Personal and family history of hereditary diseases and consanguinity between
parents were reported by 40 participants [10%], 158 [39.5%] and 175 [43.8%]
respectively. Three hundred and sixty-one [90.3%] of the total participants
were aware of the availability of premarital screening tests in Oman. A
total of 357 [89.3%] thought it is necessary to do a premarital screening
test and 367 [91.8%] agreed to carry out it in the future. The novel
contribution of this manuscript is that our logistic regression showed that
people with personal or family history of hereditary disease, and have
consanguinity between parents, being a female did not show willingness to
undertake the screening while those who are married, have higher GPA, and
older supported it. Conclusion Usability of the freely available premarital screening is low despite the
study participants awareness and willingness. Future studies should target
those who have a history of genetic disease and females as we found them not
willing to undertake the test in this study. We also recommend putting in
place mandatory rules and regulations for premarital screening tests with
better counselling strategies.

Abstract
BACKGROUND Nurse turnover is a critical challenge for healthcare organizations as it results in a decreasing nurse/patient ratio and increasing costs. AIM Identify factors influencing the termination of Filipino nurses in Ministry of Health (MOH) hospitals and record nurse recommendations to improve retention. DESIGN Cross-sectional. METHODS Data was gathered from a convenience sample of Filipino nurses with previous experience in MOH hospitals in Saudi Arabia who attended recruitment interviews at the Saudi employment office in Manila. RESULTS The sample included 124 nurses. Major turnover factors included low salary (18.3%), low nurse/patient ratio (15%), end of contract (14.5%), discrimination (13.5%), and bad accommodations (9%). Suggested areas of improvement included financial motivations (34%), administration support (25%), quality of life (25%), and work environment (16%). CONCLUSION Managing nurse turnover can be implemented on the organizational as well as at MOH levels. The recommendations given by the participants provide direct targets to improve retention. LIMITATIONS With convenience sampling, the sample is probably not representative of the Filipino nursing population. CONFLICT OF INTEREST None.
