Background: Cesarean section at the second stage of labor occurs when the mother requires delivery with full dilatation of the cervix by cesarean section (CS), which poses a risk to the mother and fetus.Purpose: To study the maternal and fetal outcomes of second-stage cesarean section. Methods: This comparative study was conducted at Alhasahisa Teaching Hospital from August 2021 to January 2022. The study sample comprised 226 women who fulfilled the inclusion criteria, including 113 who delivered by second-stage cesarean section and 113 who delivered by first-stage labor cesarean section as controls. Data were collected using a questionnaire filled out by doctors after informed consent was obtained. Results: The common indications in women who delivered via second-stage cesarean section were fetal distress in 62(51.9%), obstructed labor in 26(23%), and failure to progress in 25(22.1%). In women who underwent first-stage cesarean section, the common indications were failure to progress in 85(75.2%), fetal distress in 16(14.2%), and chorioamnionitis in 12(10.6%) (p < 0.05).  The reported maternal complications in women who underwent second-stage cesarean section were postpartum hemorrhage in 34(30.1%), sepsis in 11(9.7%), prolonged labor in eight (7.1%), extended tears in four (3.5%), umbilical cord prolapse in three (2.7%), and episiotomy in three (2.7%). The admission to the neonatal intensive care unit (NICU) and the causes of admission were more common among the babies of the women delivered by second-stage cesarean section than the babies of the women delivered by first-stage cesarean section (p value < 0.05). Maternal complications in women who underwent second-stage cesarean section included postpartum hemorrhage in 34(30.1%), sepsis in 11(9.7%), prolonged labor in 8(7.1%), uterine extension in 4(3.5%), umbilical cord prolapse in 3(2.7%), and episiotomy in 3(2.7%) (p < 0.05).Conclusion: Second-stage labor cesarean section showed more complications of postpartum hemorrhage, sepsis, and extended tears, as well as more fetal complications, such as admission to the neonatal intensive care unit, fresh stillbirths, low Apgar scores, and birth asphyxia.

Chemotherapy-Induced Peripheral Neuropathy (CIPN) is a major limiting side effect of many common chemotherapeutics often leading patients to terminate their chemotherapy treatment regimen early. The development of CIPN differs by chemotherapeutic class, with platinum- and taxane-based treatments demonstrating the highest incidence rates. Despite its relatively high prevalence, there are currently no FDA-approved treatments for CIPN, and clinicians must rely on the off-label use of several analgesics and various non-pharmacological approaches to treat CIPN symptoms in patients. Novel insights on the development of CIPN have identified new drug targets leading to several Phase II clinical trials to be initiated. Here, we describe recent advances in drug development for CIPN.

Nutritious and safe foods are essential to meet normal physiological and metabolic functions. This study evaluated heavy metals in selected food products for newborns and toddlers. These substances may result in adverse health risks and young children are extremely vulnerable due to their immature immune systems and organs. Industrialization and technological advancement have contributed to an increase in heavy metals in the soil; therefore, entering the food system in potentially harmful amounts. Safe levels have been established by monitoring agencies to reduce the presence of heavy metals. Ten national brands of baby foods were analyzed for selected heavy metals. The main ingredients ranged from vegetables, fruits, dairy, poultry, meats, and grains. The products were analyzed in triplicates using QQQ-ICP-MS instrumentation to detect the presence of arsenic, cadmium, zinc, lead, nickel, aluminum, and chromium. Based on the Agency for Toxic Substances and Disease Registry [1] guidelines for safe quantities, aluminum (4.09 µg/g and 2.50 µg/g) and zinc (33.5 µg/g 69.5 µg/g, and 30.2 µg/g) exceeded the recommended levels of 1 µg/g/day and 2 - 3 µg/g /day respectively. Mixed model analysis found significant differences in metal concentrations (F6,24 = 2.75, p = 0.03) with an average metal concentration of 0.96 µg/g. However, no significant correlations were found between the packaging materials used and the observed metal concentrations in the food samples. The study concluded that the presence of heavy metals may be due to food type and the soil on which it is grown and not the packaging materials, establishing food system contamination by heavy metals.

Background: Prophylactic dental procedures following implant placement are critical to the long-term success of implants and are also dependent on the patient maintaining effective home care.Purpose: Evaluation of the effectiveness of preventive measures in patients with diabetes during long periods after prosthetic treatment with implants.Materials and methods: The study included 62 patients with diabetes with edentulism using 146 dental implants. Patients underwent constant monitoring, including regular occupational hygiene during follow-up examinations. Their frequency was set individually from 2 to 4 times A clinical index including Bleeding on Probing (BOP), Probing Depth (PD), and Marginal Bone Loss (MBL). Results: In patients included in the preventive protocol after 12 months, the mean BOP was 1.4 ± 0.15, and PPD was 2.46 ± 0.42. After 12 months in patients mean MBL was 0.72 ± 0.6 mm, after 3 years MBL was 1.24 ± 0.25 mm. For patients who were excluded from preventive services after 12 months, the mean BOP 1.9 ± 0.25, and the mean PPD was 3.56 ± 0.28). After 12 months in patients mean MBL was 0.87 ± 0.7 mm, after 3 years MBL was 1.52 ± 0.32 mm (p > 05). Compared to persons enrolled in the preventive protocol, those in the group without services were more likely to develop peri-implantitis (42.4% vs. 12,6%). The survival rate of implants after 3 years was 98.4%. The survival rate of implants in those patients who were excluded from preventive services after 3 years was 95.4%.Conclusion: For patients with diabetes, regular medical examinations, accompanied by professional oral hygiene procedures, prevent the development of negative reactions of the soft tissues surrounding the implant.

Lead telluride (PbTe) is considered one of the most promising materials in thermoelectrics due to its unique thermoelectric properties. This semiconductor exhibits a high thermoelectric figure of merit (ZT) in certain temperature ranges, making it highly effective for converting heat energy into electricity. Additionally, PbTe is characterized by stability and low thermal conductivity, which further enhances the efficiency of thermoelectric devices. Another advantage of using PbTe is its relative affordability and high availability of raw materials. This makes it attractive for manufacturing mass thermoelectric devices such as thermoelectric modules for automobiles, industrial thermoelectric generators, heat recirculation, and others. The paper provides a review of works and an analysis of general approaches to semiconductor thermoelectric materials, including lead telluride.

Endophytic microbes i.e. bacteria, fungi, and actinomycetes live inside the plant tissues without causing any harmful effect on them. Recently, research has been conducted on endophytic microbes to enhance agriculture and environmental sustainability. Endophytes stabilize a close association with their host, which leads to major changes in plant physiology. Endophytic microbes and pathogens use the same strategies for entering the host cell. This condition may create competition between the endophytes and the pathogen. Therefore, host plants develop strategies to allow the entry of specific microorganisms. Additionally, endophytic microorganisms may temper their own genetic structure to survive and avoid the host defence machinery. The plant-endophyte symbionts promote direct and indirect defences to host plants. This plays an essential role in modulating plant defences against various stresses, particularly biotic stress. In this minireview, we highlight the interaction of endophytic microbes with their host.  As well as the role of endophytic microbes in the enhancement of plant defence systems.

There are various Extra Blood Purification Therapies (EBPTs) used in the context of critical care, including but not limited to Acute Kidney Injury (AKI). These therapies aim to remove toxins, inflammatory mediators, and excess fluids from the bloodstream. While some blood purification therapies were initially developed for renal support, they have been explored for use in other medical conditions as well, including liver pathologies and sepsis. Here is a brief explanation of some therapies such as MARS (Molecular Adsorbents Recirculating System), Prometheus, CPFA (Coupled Plasma Filtration Adsorption), PAP (Plasma Adsorption), and SPAD (Single-Pass Albumin Dialysis). Some of these therapies have entered clinical use, while others have faced challenges, such as negative evidence, poor purifying efficacy, or difficulties in practical use. The field of extracorporeal liver support is dynamic, with ongoing developments aimed at improving the effectiveness and practicality of these therapies. Sorbents mark the latest frontiers in blood purification to remove various toxic molecules, with specific emphasis on the modulation of bilirubin and other substances in critically ill patients suffering from liver failure. In the above-mentioned pathologies, substances may be continuously generated within the body, and Mass Balance is the only valuable tool for distinguishing between generation and removal processes. The effectiveness of sorbents in removing bilirubin and bile acids, as demonstrated in both in vitro and in vivo studies, distinguishes them and shows their superiority over traditional liver cleansing methods, such as CPFA, PAP, SPAD, Prometheus, and MARS.

Introduction: Hypertension is the strongest independent predictor of Coronary Artery Disease (CAD) identified by Computed tomography of coronary arteries (CTCA). In this study, CTCA-assessed Coronary Calcium Scoring (CCS) was studied in hypertensive subjects referred for CTCA.Methods: After excluding TAVI and graft assessment patients, the individual electronic health records of 410 consecutive patients who underwent CTCA between July and November 2020, were reviewed with a mean age of 58.7 years. Risk factors were recorded including smoking (38%), hyperlipidaemia (33%), positive family history (22%), systemic hypertension (48%), diabetes mellitus (30%), and male gender (46%). Referral criteria, ethnicity, cardiac, and past medical history were recorded. Patients were stratified into four groups according to CAD severity: absent, mild, moderate, and severe disease, as seen on CTCA. The mean CCS for each CAD category was compared between hypertensive and non-hypertensive patients. Mean CCS were further compared according to the number of coronary arteries affected and the severity of CAD in each artery. Results: Out of all CTCA reports, 200 (48.8%) CCS were interpreted in the very low-risk category, 80 (19.5%) low risk, 58 (14.1%) moderate risk, 23 (5.6%) moderately high risk and 49 (12.0%) high risk. A significant difference in mean CCS and CAD severity was observed between mild, moderate, and severe CAD (p = 0.015 and p < 0.001). Comparison of CCS between hypertensives and non-hypertensives, across the four CAD severity categories, revealed a significant difference in mean CCS in the severe CAD category (p = 0.03). There was no significant difference in the CCS between hypertensives with chest pain and hypertensives without chest pain. A higher number of affected coronary arteries was associated with a higher mean CCS and a significant difference in CCS was observed between hypertensive and non-hypertensive subjects for the number of arteries affected. Similar results were observed when comparing mean CCS in moderate-severely affected coronary arteries.Conclusion: Hypertensive patients with a high CCS were associated with a higher incidence of severe CAD independent of the presence of chest pain. These results suggest that the incorporation of CCS in the investigation of CAD on CT angiography may pose a powerful adjunct in proposing an alternative paradigm for the assessment of patients with hypertension, in the progress of coronary artery disease. 

The Democratic Republic of Congo (DRC) grapples with a critical shortage of nurses, exacerbating disparities in healthcare access and outcomes. This mini-review examines the factors impacting the nursing workforce in the DRC and presents potential solutions to strengthen it. Decades-long regional conflicts have endangered the nursing workforce, resulting in an imbalanced distribution that disproportionately favors urban areas over rural regions. Inadequate healthcare funding, compounded by mismanagement, has led to resource scarcity and inequitable distribution, further hampering nursing efforts. Additionally, stagnant policy reforms and ineffective advocacy have hindered improvements in nurse employment, wages, education, and working conditions. Infrastructure deficiencies and medical supply shortages have also contributed to reduced incentives for nursing professionals. Therefore, we undertook a mini-review aimed at offering a succinct and targeted overview of nursing care in the DRC. This involved analyzing available literature and data concerning the nursing workforce with a particular focus on the DRC. We believe that addressing these interlinked challenges necessitates comprehensive strategies that prioritize establishing regional stability, responsibly allocating and increasing healthcare funding, incentivizing nurse recruitment and retention through policy adjustments, enhancing healthcare infrastructure and nursing education, and fostering both local and global collaboration. Investing in nursing is paramount for transforming healthcare delivery in the DRC, particularly considering nurses' pivotal roles in delivering preventive, therapeutic, and palliative care services. Strengthening nursing capacity and addressing systemic challenges are essential steps toward mitigating healthcare disparities and enhancing population health, aligning with the objectives outlined in the United Nations Sustainable Development Goals.

Sepsis, a life-threatening condition triggered by infection, poses a significant healthcare challenge with high mortality rates. The interplay between genetics and the immune response in sepsis, particularly in surgical and trauma patients, is complex and critical. Genetic polymorphisms, particularly in cytokine genes like TNF-α, IL-6, and IL-8, have been extensively studied for their influence on sepsis susceptibility, severity, and outcomes. Polymorphisms can alter gene expression and cytokine production, leading to variations in immune responses. Studies have also explored polymorphisms concerning sepsis in genes encoding CD86, TLR4, and SIRT6. This review highlights the association between genetic polymorphisms and inflammatory responses, focusing on their impact on sepsis outcomes in surgical and trauma patients. Genetic variations play a significant role in sepsis risk, severity, and prognosis, with potential implications for personalized therapeutic strategies. Biomarkers such as cytokine gene polymorphisms may aid in predicting sepsis risk and guiding treatment decisions. Complementary therapies like acupuncture and novel biomarkers like microvesicles carrying mitochondrial content provide additional avenues for personalized sepsis management. Furthermore, multiomics approaches offer promise in predicting postoperative outcomes in surgical patients. Understanding the genetic basis of sepsis is essential for improving prevention, diagnosis, and treatment, ultimately leading to better clinical outcomes. Combining genomics, bioinformatics, and clinical expertise, precision medicine can revolutionize sepsis management by tailoring interventions to individual genetic profiles, thus enhancing patient care and outcomes.
