Clinical Characteristics and Treatment Strategies for Group B Streptococcus (GBS) Infection in Pediatrics: A Systematic Review.

Background and Objectives: Group B streptococcus (GBS) is the leading cause of infections in neonates with high fatality rates. GBS is caused by the streptococcus bacterium known as streptococcus agalactiae, which is highly contagious and can be transmitted from pregnant women to infants. GBS infection can occur as an early onset or late-onset infection and has different treatment strategies. Antibiotics are effective in treating GBS infections at early stages. The aim of this systematic review was to summarize the clinical characteristics and treatment strategies for GBS, with a focus on antibiotics. Material and Methods: The findings of this review were reported in accordance with the PRISMA 2020 guidelines and a flow diagram of the study selection process, a summary of the included studies, a description of the study characteristics, a summary of the results, a discussion of the implications of the findings, and a conclusion are included. Overall, the authors followed a rigorous methodology to ensure that this review is comprehensive and inclusive of relevant studies on GBS infection and its treatment. Results: Overall, 940 studies were reviewed and only the most relevant 22 studies were included in the systematic review. This review describes the characteristics of patients in different studies related to early onset GBS disease and presents various treatment strategies and outcomes for GBS infection in pediatrics. The studies suggest that preventive measures, risk-based intrapartum antibiotic prophylaxis, and maternal vaccination can significantly reduce the burden of GBS disease, but late-onset GBS disease remains a concern, and more strategies are required to decrease its rate. Improvement is needed in the management of the risk factors of GBS. A conjugate vaccine with a serotype (Ia, Ib, II, III, and V) has been proven effective in the prevention of GBS in neonates. Moreover, penicillin is an important core antibiotic for treating early onset GBS (EOD). Conclusions: This systematic review summarizes the treatment comparison for GBS infections in neonates, with a primary focus on antibiotics. IAP (intrapartum antibiotic prophylaxis) according to guidelines, antenatal screening, and the development of a conjugate vaccine may be effective and could lower the incidence of the disease.

Gender and cytoarchitecture differences: Functional connectivity of the hippocampal sub-regions.

Introduction: The hippocampus plays a significant role in learning, memory encoding, and spatial navigation. Typically, the hippocampus is investigated as a whole region of interest. However, recent work has developed fully detailed atlases based on cytoarchitecture properties of brain regions, and the hippocampus has been sub-divided into seven sub-areas that have structural differences in terms of distinct numbers of cells, neurons, and other structural and chemical properties. Moreover, gender differences are of increasing concern in neuroscience research. Several neuroscience studies have found structural and functional variations between the brain regions of females and males, and the hippocampus is one of these regions. Aim: The aim of this study to explore whether the cytoarchitecturally distinct sub-regions of the hippocampus have varying patterns of functional connectivity with different networks of the brain and how these functional connections differ in terms of gender differences. Method: This study investigated 200 healthy participants using seed-based resting-state functional magnetic resonance imaging (rsfMRI). The primary aim of this study was to explore the resting connectivity and gender distinctions associated with specific sub-regions of the hippocampus and their relationship with major functional brain networks. Results: The findings revealed that the majority of the seven hippocampal sub-regions displayed functional connections with key brain networks, and distinct patterns of functional connectivity were observed between the hippocampal sub-regions and various functional networks within the brain. Notably, the default and visual networks exhibited the most consistent functional connections. Additionally, gender-based analysis highlighted evident functional resemblances and disparities, particularly concerning the anterior section of the hippocampus. Conclusion: This study highlighted the functional connectivity patterns and involvement of the hippocampal sub-regions in major brain functional networks, indicating that the hippocampus should be investigated as a region of multiple distinct functions and should always be examined as sub-regions of interest. The results also revealed clear gender differences in functional connectivity.

Physical therapists' perceptions of and satisfaction with delivering telerehabilitation sessions to patients with knee osteoarthritis during the Covid-19 pandemic: Preliminary study.

OBJECTIVE: This preliminary study was conducted to explore physical therapists' (PT) perceptions of and satisfaction with delivering telerehabilitation sessions to patients with knee osteoarthritis during the Covid-19 pandemic. STUDY DESIGN: An exploratory preliminary study using an internet-based survey followed by focus group sessions. METHODS: A programme of sessions was administered by 12 PTs from the Physical Therapy Department at Prince Sultan Military Medical City. An internet-based survey containing 17 statements was completed by the PTs. RESULTS: With regard to telephone-delivered care, four statements related to patients' privacy, programme convenience, safe patients time and money achieved consensus agreement (≥75% agreed or strongly agreed), there was majority agreement (≥50% of respondents agreed or strongly agreed) with seven of the statements regarding the effectiveness, affordability and safety of the programme, but there was no consensus with regard to the remaining five statements. In addition, most of the participants (84.6%) believed that a telephone consultation should cost 25% or 50% less than a face-to-face session. CONCLUSION: Despite the lack of physical contact with patients, the PTs agreed that telerehabilitation would offer patients an easy method of being prescribed a therapeutic programme, save time and money, and maintain patient privacy. Further, the PTs reported barriers and suggested adaptations for this method of service delivery.
