RESUMEN
Background: Single-incision laparoscopic cholecystectomy (SILC) is a minimally invasive procedure designed to minimize the number and size of the incisions needed for cholecystectomy. Titanium clips are traditionally used to close the cystic duct and artery. Although it is considered safe, dislodgement can result in bleeding and biliary leakage. Using LigaSure for duct sealing is still controversial. The aim of this study was to evaluate the safety and feasibility of using LigaSure to close the cystic duct during SILC. Methods: A prospective study over two years was conducted at the General Surgery Department, Mansoura University Hospital, on 102 patients, 51 in each group. They underwent SILC using LigaSure (Group 1) or titanium clips (Group 2) to control the cystic duct and artery. Results: The data analyzed included demographic data, operative time, intra- and postoperative complications, postoperative pain, and hospital stay. The operative time was significantly shorter in LigaSure group (68.5 ± 9.8 versus 72.9 ± 10.6 minutes in the clips group, P .03). There was no significant difference between the two groups regarding postoperative bile leak or bleeding. However, two cases in Group 1 and four cases in Group 2 were converted to multiple port laparoscopic cholecystectomy; this was statistically nonsignificant. Postoperative pain and hospital stay showed no significant difference between the two groups. Two patients in each group developed port-site incisional hernia. Conclusions: Clipless SILC using LigaSure is a feasible and safe procedure with acceptable morbidity with shorter operative time than SILC using clips. Nevertheless, the risk of port-site incisional hernia should be explained to the patients.
RESUMEN
Background: Anterior lamellar keratoplasty (ALK) is a less invasive procedure than PK, and thus avoids many of the intraocular complications associated with PK. DALK can be performed using several different techniques, with either a manual dissection, a keratome or femtosecond-laser assisted dissection, or with a big bubble technique. To analyse the outcomes and compare the results of three deep anterior lamellar keratoplasty (DALK) techniques. Methods: This study included 105 DALK cases performed at Queen Victoria Hospital, East Grinstead, UK, in the period between January 2016 and May 2022. Cases were classified into four groups based on technique: BB-DALK, manual DALK, FS-DALK and 'converted to PK group'. Results: There was significant improvement in VA and Kmax compared to the preoperative values in all groups. There was no significant difference detected in VA and Kmax between all groups. Conclusions: Performing DALK surgery with any suitable technique (manual, big-bubble or femtosecond-assisted) is effective and causes significant improvements in VA and Kmax, even in cases where a conversion to penetrating keratoplasty is required. However, every technique has its pros and cons and should be tailored according to surgeon preference and individual case pathology.
RESUMEN
BACKGROUND: Moderate laryngomalacia lies in the grey zone where the parents and treating team might hesitate to decide the treatment plan for the child. Neurodevelopmental assessment of the child was neither assessed nor incorporated in surgical decision-making in the past. OBJECTIVES: To evaluate the neurodevelopmental outcome of moderate laryngomalacia treatment strategies (surgery versus conservative). METHODS: We conducted an observational multicentric cohort study. We compared two groups of patients according to their moderate laryngomalacia treatment strategy: surgical treatment and no treatment. The neurodevelopmental outcome was assessed by Griffiths-III developmental scales. RESULTS: A total of 150 children were diagnosed with moderate laryngomalacia of which 56 were successfully treated with surgery and 94 improved without intervention. The median Griffiths-III developmental quotients (DQs) of subscales A, B, C, E, and general development were significantly higher in the surgically treated group compared to conservatively treated ones. CONCLUSION: Untreated moderate laryngomalacia cases have worse neurodevelopmental outcomes than surgically treated cases.

Kikuchi-Fujimoto disease (KFD), also known as histiocytic necrotizing lymphadenitis, is a rare, benign condition affecting young Oriental-Asian females. It is characterized by fever and tender cervical lymphadenopathy with an unclear aetiology, and in most longitudinal reviews, KFD occurs before systemic lupus erythematosus (SLE). Herein, the case of a 28-year-old Kuwaiti female without any relevant past medical history, who was simultaneously diagnosed with KFD and SLE following an Ebstein-Barr virus infection, is reported. The patient was treated with oral prednisolone, hydroxychloroquine, cyclosporin, and belimumab and her response was clinically and biochemically favourable. Although KFD is prevalent in Asian populations, it may affect all races. Early diagnosis of KFD is difficult, particularly when simultaneously diagnosed with SLE, but crucial to preventing inappropriate therapy. Clinicians need to know about this rare disease, especially when patients present with fever and swollen lymph nodes, due to a risk of misdiagnosis with tuberculosis or lymphoma, as these are more often thought to be the cause of such symptoms.

Anorectal sepsis is a common and potentially serious medical condition characterized by infection and inflammation of the anal canal and surrounding tissues. However, the lack of standardized and comprehensive scoring systems specifically tailored for predicting the severity of anorectal sepsis poses challenges in clinical practice. This study aimed to develop and validate a scoring system for predicting the severity of anorectal sepsis by incorporating relevant patient factors. A retrospective cohort study was conducted at Mansoura University Hospital, a tertiary care center, over a period of 5 years. The study population consisted of 330 patients diagnosed with anorectal sepsis during the study period. A scoring system was developed using multiple variables, with each variable assigned a specific score based on its clinical significance and weight in predicting disease severity. The developed scoring system's predictive performance was evaluated using receiver operating characteristic (ROC) analysis, calculating the area under the ROC curve to assess discriminative ability. Descriptive statistics were used to summarize the demographic and clinical characteristics of the study population. Chi-square tests or t tests were performed to assess differences between non-severe and severe anal sepsis groups. The scoring system consisted of 12 variables, with a maximum total score of 18. The logistic regression analysis revealed significant associations between localized swelling, presentation within 72 hours, multiple drainage sessions, and severe anorectal sepsis. The ROC analysis showed an area under the curve of 0.85, indicating good discriminative ability of the scoring system. The scoring system was developed and validated in a single center, which may limit its generalizability to other settings. The scoring system demonstrated good predictive performance and can be a valuable tool for clinicians in assessing disease severity, guiding treatment decisions, and identifying high-risk patients.

The efficient and sustainable supply and transport of water is a key component to any functioning civilisation making the role of urban water systems (UWS) inherently crucial to the wellbeing of its customers. However, managing water is not a simple task. Whether it is ageing infrastructure, transient flows, air cavities or low pressures; water can be lost as a result of many issues that face UWSs. The complexity of those networks grows with the high urbanisation trends and climate change making water companies and regulatory bodies in need of new solutions. So, it comes as no surprise that many researchers are invested in innovating within the water industry to ensure that the future of our water is safe. Deep reinforcement learning (DRL) has the potential to tackle complexities that used to be very challenging as it relies on deep neural networks for function approximation and representation. This technology has conquered many fields due to its impressive results and can effectively revolutionise UWS. In this article, we explain the background of DRL and the milestones of this field using a novel taxonomy of the DRL algorithms. This will be followed by with a novel review of DRL applications in the UWS which focus on water distribution networks and stormwater systems. The review will be concluded with critical insights on how DRL can benefit different aspects of urban water systems.

Phytase is crucial in enhancing the bioavailability and release of phosphorus and other nutrients bound to phytic acid, making them more bioavailable for animal absorption. This study was carried out to inspect the effect of supplementing low phosphorus (P) diet with di-calcium phosphate (DCP) and liquid phytase enzyme (LP), which contains 1500 FTU/kg, on growth performance, intestinal morphometry, proximate body chemical composition, blood profile, immunity status, liver mitochondrial enzyme activities, the expression response and economic returns of Nile tilapia (Oreochromis niloticus). Three triplicate groups of fish (initial weight 5.405 ± 0.045 g, N = 90) were fed on three different diets for 90 days. The first was a control diet with zero DCP; the second was a control diet supplemented with 0.71% DCP; the third was a control diet supplemented with 0.03% LP. The groups were designated as CG, DCP and LP, respectively. Results showed that LP induced considerable improvements (p < 0.05) in FBW, body weight gain, weight gain rate, specific growth rate, HIS, viscero-somatic index, spleen-somatic index, feed conversion ratio, blood parameters and the histomorphometry assessment of intestinal villi absorptive capacity, compared with the other groups. Also, whole-body protein and lipid contents pointedly (p < 0.05) increased by LP, compared with the DCP group. A positive response (p < 0.05) to the phytase enzyme was noted in complexes I, III and IV of the mitochondrial liver complex enzyme activity. Likewise, the relative gene expression levels of (GHr-1, IGF-1, FAS and LPL) were notably (p < 0.05) upregulated by phytase enzyme, associated with DCP and control groups. Further, phytase recorded the highest total return and profit percentage. It can be concluded that Nile tilapia benefits from using phytase enzyme 1500 FTU/kg at 0.03% without adding DCP in terms of good performance and profits.

Trans-abdominal preperitoneal (TAPP) and totally extraperitoneal (TEP) repairs are the available surgeries for inguinal hernias, with both methods of laparoscopic repairs requiring mesh applications. This study analyzes the correlation between sutured versus stapler mesh fixation in a laparoscopic TAPP for unilateral groin hernia regarding chronic pain during 3-year follow-up. A total of 130 patients with laparoscopic hernia undergoing TAPP repair were randomized into 2 groups based on their fixation technique-one with sutures and the other with stapler. Postoperative complications and chronic groin pain were noted for each technique. Equal number of participants was present in the stapler and suture groups, with the majority having an ASA score of one. The mean age was 42.50 ± 13.86 years, and the body mass index (BMI) was 27.47 ± 5.88. The stapler group presented a shorter mean operative time than the suture group. However, the stapler group had a significantly higher mean VAS score than the suture group. Most participants in the suture group (89.2%) had LOS for 1 day, while a 2-day LOS was significantly higher in the stapler group (12.3%) than in the suture group (9.2%). No patient reported mesh erosion, conversion, recurrence, testicular atrophy, and mesh infection. Early postoperative pain was more in stapler group along with long hospital stay, but both were non-significant. Chronic postoperative pain results and recurrence incidences over 3-year follow-up were also similar. Re-admission rates were minimal, no significant complications occurred.

OBJECTIVE: To determine the superiority of aerobic exercise (AE) interventions on key outcomes of stroke recovery, including cardiorespiratory fitness (VÌO2peak, primary outcome), systolic blood pressure (SBP) and mobility (6 min Walk Test (6MWT) distance and 10 m Usual Gait Speed) after stroke. DATA SOURCES: MEDLINE, EMBASE, Web of Science, CINAHL, CENTRAL, SPORTDiscus, PsycINFO and AMED Allied and Complementary Medicine were searched from inception to February 2023. ELIGIBILITY CRITERIA: Randomised controlled trials were included that compared the effects of any AE interventions (low-intensity, moderate-intensity, high-intensity continuous training (HICT), high-intensity interval training (HIIT)) to no exercise, usual care or other AE interventions in individuals poststroke. ANALYSES: Systematic review with Bayesian network meta-analysis (NMA) methodology was employed. Surface under the cumulative ranking curve (SUCRA) values were used to rank interventions. The Grading of Recommendations, Assessment, Development and Evaluation minimally contextualised framework for NMA was followed. RESULTS: There were 28 studies (n=1298) included in the NMA for VÌO2peak, 11 (n=648) for SBP, 28 (n=1494) for 6MWT and 18 (n=775) for the 10 m Usual Gait Speed. The greatest effect on VÌO2peak, 6MWT and 10 m Usual Gait Speed was observed after HIIT and HICT. No differences between interventions were found for SBP. SUCRA values identified HIIT as the superior AE intervention for all outcomes of interest. HIIT was the most effective intervention for improving VÌO2peak (2.9 mL/kg/min (95% credible interval 0.8 to 5.0) moderate certainty) compared with usual care. CONCLUSION: This NMA suggests that higher-intensity AE is superior to traditional low-intensity to moderate-intensity AE for improving outcomes after stroke.

Lymphatic flow and anatomy can be challenging to study, owing to variable lymphatic anatomy in patients with diverse primary or secondary lymphatic pathologic conditions and the fact that lymphatic imaging is rarely performed in healthy individuals. The primary components of the lymphatic system outside the head and neck are the peripheral, retroperitoneal, mesenteric, hepatic, and pulmonary lymphatic systems and the thoracic duct. Multiple techniques have been developed for imaging components of the lymphatic system over the past century, with trade-offs in spatial, temporal, and contrast resolution; invasiveness; exposure to ionizing radiation; and the ability to obtain information on dynamic lymphatic flow. More recently, dynamic contrast-enhanced (DCE) MR lymphangiography (MRL) has emerged as a valuable tool for imaging both lymphatic flow and anatomy in a variety of congenital and acquired primary or secondary lymphatic disorders. The authors provide a brief overview of lymphatic physiology, anatomy, and imaging techniques. Next, an overview of DCE MRL and the development of an MRL practice and workflow in a hybrid interventional MRI suite incorporating cart-based in-room US is provided, with an emphasis on multidisciplinary collaboration. The spectrum of congenital and acquired lymphatic disorders encountered early in an MRL practice is provided, with emphasis on the diversity of imaging findings and how DCE MRL can aid in diagnosis and treatment of these patients. Methods such as DCE MRL for assessing the hepatic and mesenteric lymphatic systems and emerging technologies that may further expand DCE MRL use such as three-dimensional printing are introduced. ©RSNA, 2024 Test Your Knowledge questions for this article are available in the supplemental material.

Abstract Introduction It is now evident that the loss of smell and/or taste may be consistent accompanying symptoms of the SARS-CoV-2 infection. Objective To estimate the social behavior of recent anosmic non-hospitalized patients in the COVID-19 pandemic and to try to obtain the natural pattern in society in a cross-sectional study. Methods A cross-sectional study conducted on 4,860 patients with anosmia complaints during the COVID-19 pandemic. Patients who needed a consultation for an anosmia complaint confirmed that they had completed the survey regarding age, gender, history of general diseases, history of nasal disease, associated COVID-19 symptoms, smoking, blood group, and risk factors. Results A total of 4,860 patients with a mean age of 34.26 ± 11.91 years completed the study. There was a predominance of female patients: 3,150 (58.9%). Most patients (4,083 patients; 83%) developed sudden anosmia. In 85% (4131 patients) of the patients, a previous history of contact with anosmic patients was present. The most prevalent blood group was O (39%). In total, 67.4% of the patients underwent medical treatment. A history of unusual influenza attacks in December 2020 was reported by by 27% (1312 patients) of the patients. Conclusion Despite large diversity of behaviors among anosmic patients in the COVID-19 pandemic, we can observe a great similarity in the pattern of anosmia in non-hospitalized patients, especially in the way it spreads, the predisposing factors, and the individual recovery.
