Previous studies on telemedicine have either focused on its role in the management of chronic diseases in general or examined its effectiveness in comparison to standard post-discharge care. Little has been done to determine the comparative impact of different telemedicine options for a specific population such as individuals with heart failure (HF). Systematic reviews (SR) of randomized controlled trials (RCTs) that examined telephone support, telemonitoring, video monitoring or electrocardiographic monitoring for HF patients were identified using a comprehensive search of the following databases: MEDLINE, EMBASE, CINAHL and The Cochrane Library. Studies were included if they reported the primary outcome of mortality or any of the following secondary outcomes: all-cause hospitalization and heart failure hospitalization. Thirty RCTs (N = 10,193 patients) were included. Compared to usual care, structured telephone support was found to reduce the odds of mortality(Odds Ratio 0.80; 95% Credible Intervals [0.66 to 0.96]) and hospitalizations due to heart failure (0.69; [0.56 to 0.85]). Telemonitoring was also found to reduce the odds of mortality(0.53; [0.36 to 0.80]) and reduce hospitalizations related to heart failure (0.64; [0.39 to 0.95]) compared to usual post-discharge care. Interventions that involved ECG monitoring also reduced the odds of hospitalization due to heart failure (0.71; [0.52 to 0.98]). Much of the evidence currently available has focused on the comparing either telephone support or telemonitoring with usual care. This has therefore limited our current understanding of how some of the less common forms of telemedicine compare to one another. Compared to usual care, structured telephone support and telemonitoring significantly reduced the odds of deaths and hospitalization due to heart failure. Despite being the most widely studied forms of telemedicine, little has been done to directly compare these two interventions against one another. Further research into their comparative cost-effectiveness is also warranted.

APOL1, a secreted high-density lipoprotein, is expressed in different human tissues. Genetic variants of APOL1 are described to be associated with the development of end stage renal diseases in African Americans. In human kidney, APOL1 is mainly expressed in podocytes that are responsible for proper blood filtration. Since mice do not express ApoL1, the zebrafish is an ideal model to study the role of ApoL1. Injection of morpholinos against zApoL1 into zebrafish eggs and larvae, respectively, induces severe edema indicating a leakage of the filtration barrier. This was demonstrated in zApoL1 knockdown larvae by intravascular injection of fluorescently-labeled 10- and 500-kDa dextrans and by clearance of the vitamin D-binding protein from the circulation. Immunohistochemistry and RT-PCR revealed the reduction of nephrin, a podocyte-specific protein essential for blood filtration. Coinjection of human nephrin mRNA rescued the zApoL1 knockdown induced phenotype. Reduced APOL1 and nephrin levels were also found in biopsies of patients suffering from end stage renal diseases. Our results demonstrate that zApoL1 is essential for proper blood filtration in the zebrafish glomerulus and that zApoL1 affects the expression of nephrin.

Idiopathic forms of Focal Segmental Glomerulosclerosis (FSGS) are caused by circulating permeability factors, which can lead to early recurrence of FSGS and kidney failure after kidney transplantation. In the past three decades, many research endeavors were undertaken to identify these unknown factors. Even though some potential candidates have been recently discussed in the literature, “the” actual factor remains elusive. Therefore, there is an increased demand in FSGS research for the use of novel technologies that allow us to study FSGS from a yet unexplored angle. Here, we report the successful treatment of recurrent FSGS in a patient after living-related kidney transplantation by removal of circulating factors with CytoSorb apheresis. Interestingly, the classical published circulating factors were all in normal range in this patient but early disease recurrence in the transplant kidney and immediate response to CytoSorb apheresis were still suggestive for pathogenic circulating factors. To proof the functional effects of the patient’s serum on podocytes and the glomerular filtration barrier we used a podocyte cell culture model and a proteinuria model in zebrafish to detect pathogenic effects on the podocytes actin cytoskeleton inducing a functional phenotype and podocyte effacement. We then performed Raman spectroscopy in the < 50 kDa serum fraction, on cultured podocytes treated with the FSGS serum and in kidney biopsies of the same patient at the time of transplantation and at the time of disease recurrence. The analysis revealed changes in podocyte metabolome induced by the FSGS serum as well as in focal glomerular and parietal epithelial cell regions in the FSGS biopsy. Several altered Raman spectra were identified in the fractionated serum and metabolome analysis by mass spectrometry detected lipid profiles in the FSGS serum, which were supported by disturbances in the Raman spectra. Our novel innovative analysis reveals changed lipid metabolome profiles associated with idiopathic FSGS that might reflect a new subtype of the disease.

Hepatitis E Virus (HEV) is a globally widespread pathogen that causes acute hepatitis infection. Beyond hepatic pathogenesis, HEV has been proven to cause several extrahepatic manifestations, such as neurological, renal, and hematological manifestations. It was also associated with mortality in pregnant females. Several studies have investigated the impact of HEV on the male reproductive system; however, the available data are limited and conflicting. Assessment of the patients’ ejaculates/semen samples revealed that HEV particles are excreted in these fluids in cases of chronic infection but not acute infection. The excreted HEV particles are infectious to in vivo animal models and in vitro cell culture. However, the effect of HEV infection on male infertility is not confirmed. One study including human samples showed male infertility associated with HEV genotype 4 infection. Studies of HEV infection in animal models such as pigs, gerbils, and mice showed that HEV infection caused distortion on the testes, damage of the blood–testis barrier, and induction of inflammatory responses leading to abnormalities in the sperm. The excretion of HEV in the semen fluids raises concerns about HEV transmission via sexual transmission. However, all available data do not confirm the transmission of HEV through sexual intercourse. This review aims to summarize and critically assess the available studies investigating the influence of different HEV genotypes on the male reproductive system, providing insights into whether HEV contributes to reproductive impairment in men.

Dedifferentiation and loss of podocytes are the major cause of chronic kidney disease. Dach1, a transcription factor that is essential for cell fate, was found in genome‐wide association studies to be associated with the glomerular filtration rate. We found that podocytes express high levels of Dach1 in vivo and to a much lower extent in vitro. Parietal epithelial cells (PECs) that are still under debate to be a type of progenitor cell for podocytes expressed Dach1 only at low levels. The transfection of PECs with a plasmid encoding for Dach1 induced the expression of synaptopodin, a podocyte‐specific protein, demonstrated by immunocytochemistry and Western blot. Furthermore, synaptopodin was located along actin fibres in a punctate pattern in Dach1‐expressing PECs comparable with differentiated podocytes. Moreover, dedifferentiating podocytes of isolated glomeruli showed a significant reduction in the expression of Dach1 together with synaptopodin after 9 days in cell culture. To study the role of Dach1 in vivo, we used the zebrafish larva as an animal model. Knockdown of the zebrafish ortholog Dachd by morpholino injection into fertilized eggs resulted in a severe renal phenotype. The glomeruli of the zebrafish larvae showed morphological changes of the glomerulus accompanied by down‐regulation of nephrin and leakage of the filtration barrier. Interestingly, glomeruli of biopsies from patients suffering from diabetic nephropathy showed also a significant reduction of Dach1 and synaptopodin in contrast to control biopsies. Taken together, Dach1 is a transcription factor that is important for podocyte differentiation and proper kidney function.

Background Nurse interns’ capacity for innovative behavior is a key component of healthcare settings because of increasing demands and complexities. Thus, it is important to find strategies that promote their innovative behavior. The development of psychological capital (PsyCap) improves positive behaviors and attitudes, such as engagement, motivation, and satisfaction, in the work environment. Therefore, this study aimed to assess the effect of a PsyCap educational program on nurse interns’ innovative behavior. Methods A quasi-experimental design was used in this study. This study was executed at Fayoum University hospitals. The study participants comprised all the available nurse interns ( n  = 223) registered in the internship year (2022–2023) in the aforementioned settings. The data were gathered using three instruments, namely, the PsyCap Knowledge Questionnaire, the PsyCap Questionnaire, and the Innovative Behavior Inventory. Results The nurse interns’ mean scores regarding total knowledge about PsyCap, total perception of PsyCap, and total perception of innovative behavior significantly improved through the posttest phase (41.27 ± 9.31, 92.22 ± 6.26, 91.31 ± 9.06, respectively) and the follow-up phase (37.83 ± 8.83, 89.96 ± 6.31, 88.89 ± 8.33) in comparison with the pretest phase (14.39 ± 5.83, 69.04 ± 8.13, 60.55 ± 7.15). Conclusion The PsyCap educational program was effective and beneficial for improving the nurse interns’ perceptions of innovative behavior. Therefore, PsyCap interventions should be implemented in hospitals through professional development programs and orientation programs.

ObjectiveTo assess the relative effects of individual testosterone products among hypogonadal men.DesignSystematic review and network meta-analysis.MethodsWe searched MEDLINE, Embase, Cochrane CENTRAL, and grey literature (25 May 2017) for randomised-controlled trials (RCTs) and non-randomised studies (NRS) that involved hypogonadal men given testosterone replacement therapy (TRT) for ≥3 months. Comparators were placebo, another TRT, or the same product at a different dose. Outcomes were quality of life, depression, libido, erectile function, activities of daily living and testosterone levels, as well as cardiovascular death, myocardial infarction, stroke, prostate cancer, heart disease, diabetes, serious adverse events, withdrawals due to adverse events and erythrocytosis. RCT data were pooled via meta-analysis and network meta-analysis. Risk of bias was assessed using Cochrane’s risk of bias tool (RCTs) andScottish Intercollegiate Guidelines Network (SIGN)50 (NRS).ResultsEighty-seven RCTs and 51 NRS were included. Most were at high or unclear risk of bias, with short treatment duration and follow-up. When compared as a class against placebo, TRT improved quality of life (standardised mean difference (SMD) −0.26, 95% CI −0.41 to –0.11), libido (SMD 0.33, 95% CI 0.16 to 0.50), depression (SMD −0.23, 95% CI −0.44 to –0.01) and erectile function (SMD 0.25, 95% CI 0.10 to 0.41). Most individual TRTs were significantly better than placebo at improving libido (6/10). Only one TRT was better than placebo at improving quality of life, and no individual TRTs improved depression or erectile function. There was no increased risk of adverse events, with the exception of withdrawals due to adverse events with the use of some TRTs.ConclusionDespite a class effect of improving quality of life, depression, erectile function and libido, major improvements were not observed with the use of any individual product. We observed no statistically significant increase in the risk of adverse events; however, longer-term high-quality trials are needed to fully assess the risk of harm.PROSPERO registration number CRD42014009963.

An integrated geophysical survey using land magnetic and ground penetrating radar (GPR) methods was conducted to investigate the archaeological findings and ancient cultural relics at an undiscovered 100 m × 60 m in Tal-Baltus in El-Sadat city, Menofia Governorate, Egypt. The study area at Tal-Baltus was chosen among several archaeological hills in the Menofia governorate due to its archaeological significance in the Greco-Roman history of Egypt. The total area was first surveyed using the magnetic method, and then two small promising sites within this area were selected for the GPR survey. The obtained magnetic results showed the presence of remarkably high anomalies with different shapes of irregular geometry. Therefore, they are interpreted as ruins of old storage rooms related to an ancient harbor-shaped structure. Besides, numerous scattered pillars and column heads were also delineated and matched with remains of granite blocks in abundance in the study area, taking the same trend as the delineated magnetic anomalies. In addition, the GPR results highlighted several hyperbolas with variable amplitudes and sizes, which have been interpreted as the shallow foundation of a potential ancient harbor made of limestone. The comprehensive interpretation of the integrated magnetic and GPR surveys strongly suggests that the study area may be a part of an ancient harbor in addition to some other ancillary room-shaped structures used for cargo storage purposes and scattered portions of walls and pillars dating back to the Greco-Roman era.

The RAS family of oncoproteins (KRAS, HRAS, and NRAS) drive aggressive cancers like pancreatic ductal adenocarcinoma (PDAC) and non-small cell lung cancer (NSCLC), yet targeting mutant RAS has historically been challenging due to its “undruggable” structure. Recent advances in mutation-specific inhibitors (e.g., sotorasib for KRASG12C) have demonstrated clinical efficacy but face limitations in tumor types like PDAC, where KRASG12C mutations are rare. Broad-spectrum pan-RAS inhibitors (e.g., RMC-7977, RMC-6236, ADT-007/ADT-1004) now offer promise by targeting active GTP-bound or nucleotide-free RAS across isoforms and mutations. Preclinical studies show these agents induce deep tumor regressions, overcome resistance to allele-specific inhibitors, and remodel the tumor microenvironment (TME) by enhancing T-cell infiltration and reducing immunosuppressive myeloid cells. Early clinical data for RMC-6236 report disease control rates of 85–87% in NSCLC and PDAC, with manageable toxicity. This review shows that pan-RAS inhibitors represent a promising new class of therapeutics capable of overcoming many historical challenges associated with the “undruggable” nature of RAS proteins and demonstrating encouraging preclinical and early clinical results, particularly in difficult-to-treat tumor types such as PDAC and NSCLC. Challenges remain in achieving a therapeutic index due to RAS’s role in normal tissue homeostasis, but tumor-specific drug accumulation and rapid normal tissue recovery may mitigate risks. Ongoing trials are evaluating combination strategies with immunotherapy and chemotherapy, positioning pan-RAS inhibitors as transformative agents for RAS-driven cancers.

Introduction Severe congenital ptosis poses a complex challenge for oculoplastic surgeons, requiring meticulous surgical intervention to restore eyelid function and improve aesthetic outcomes mainly by using frontalis sling approach. A crucial issue in frontalis sling surgeries is the sustainability of effect. Purpose This retrospective study reports the outcomes of two surgical techniques for treating severe congenital ptosis in the paediatric age group: Silicon rods ptosis sling and a novel technique involving the use of Silicon rods with green braided polyester (Ethibond) sutures to secure the rods in place “sling for the sling”. Methods The medical records of children who underwent frontalis suspension were reviewed in a retrospective fashion. We identified two groups; the first group (20 patients: 35 eyelids) had the traditional frontalis suspension surgery using silicone suspension set, the second group (14 patients: 25 eyelids) was operated using the new “sling for sling” technique. We used the postoperative marginal reflex distance-1 (MRD-1) as the primary outcome measure while the frequency of both wound related complications and recurrence were considered as secondary outcome measures. Post operative data were collected and compared after 1 month, 6 months, 12 months, and 18 months. Results Preliminary results indicate promising outcomes for both techniques, with significant improvement in eyelid elevation observed in both groups. However, the novel technique using Silicon rods with Ethibond sutures demonstrated enhanced sustainability, leading to a more durable outcome with significantly less recurrence. Conclusion This study highlights the potential benefits of the novel technique in treating severe congenital ptosis and introduces an innovative approach to Silicone rods fixation to achieve a long-term corrective effect.
