Association of CTLA-4 gene polymorphisms with the genetic susceptibility and prognosis of patients with Bladder urothelial carcinoma

To assess the association of cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) gene polymorphisms with the prognosis of patients with Bladder urothelial carcinoma (BUC). From February 2019 to October 2020, 256 BUS patients treated at the Xinxiang Central Hospital were selected as the study group, whilst 250 healthy individuals were selected as the control group. Genotypes of rs5742909 (-318C/T), rs231775 (+49A/G) and rs4553808 (-1661A/G) were determined by PCR-restriction fragment length polymorphism assay. The frequencies of genotypes and alleles of the CTLA-4 gene were compared between the two groups. All patients had undergone surgical treatment and were followed up for 3 years and divided into good prognosis group (n = 166) and poor prognosis group (n = 86) based on the status of disease. The distribution of alleles and genotypes were compared, and Kaplan-Meier analysis was used to assess the association of genetic polymorphisms with the prognosis. No significant difference was found in the gender, age, BMI, smoking history and alcohol use between the two groups (P > 0.05). The frequencies of GG genotype and G allele for the rs231775 (+49A/G) and rs4553808 (-1661A/G) loci were significantly higher in the study group compared with the control group (P < 0.05), whilst no statistical difference was found in the genotypic and allelic frequency for the rs5742909 locus between the two groups (P > 0.05). Among the 252 subjects who had completed follow-up, 86 had poor prognosis and 166 had good prognosis. The frequencies of GG genotype and G allele at the rs231775 (+49A/G) and rs4553808 (-1661A/G) loci were significantly lower in the good prognosis group compared with the poor prognosis group (P < 0.05). Kaplan-Meier survival curve analysis showed that the survival time of patients with GG genotype for the rs231775 (+49A/G) and rs4553808 (-1661A/G) loci was significantly shorter than patients with AA or AG genotypes (Log Rank 2 = 13.654, 9.974, P < 0.001). The polymorphisms of the rs231775 and rs4553808 loci of the CTLA-4 gene are associated with genetic susceptibility and poor prognosis for BUC, and a higher GG genotypic frequency may increase the risk for infection and poor prognosis of the patients.

Evaluation of the effect of dextrose prolotherapy versus deep dry needling therapy for the treatment of temporomandibular joint anterior disc displacement with reduction: (a randomized controlled trial).

to compare the combined effect of Prolotherapy and Deep Dry Needling (DDN) versus DDN effect on relieving the symptoms of Temporomandibular joint (TMJ) anterior disc displacement. The clinical trial randomly allocated forty patients. The (control group) patients received four intraarticular and masseteric DDN sessions, while the (study group) patients were subjected to the exact technique followed by Prolosolution injection. The baseline preoperative measurements included Maximal interincisal opening (MIO), auscultation of the presence of clicking, and Visual Analogue Scale (VAS), which were repeated for postoperative measurements after one, two, five, and eight months. By the end of the study, all patients expressed apparent improvement in pain MIO and clicking. The inter- and intragroup comparison revealed that the pain score values of the control group after five and eight months were significantly higher than those of the study group. The study group demonstrated more significant MIO calibration than the control group, with insignificant differences between both groups regarding the presence of clicking at any time interval. The associations between clicking and VAS values, between clicking and MIO, and between VAS values and increased MIO were positive in the test group and negative in the control group. Dextrose Prolotherapy and DDN were beneficial. However, Prolotherapy demonstrated more significant, sustained, and correlated long-term alleviation of symptoms and increased MIO. The study assesses the sole effect of dextrose prolotherapy on relieving the signs of TMJ anterior disc displacement apart from the impact of the penetrating needle. The study was registered on www. gov (#: NCT05821985) by Ahmed Nagi Alghandour.

Lasmiditan ameliorates serotonergic itch in mice: Possible involvement of 5-HT1F receptors.

Previously, some allergic conditions involving pruritus have been linked to migraine, raising the possibility that migraine and itching may be governed by similar underlying mechanisms. We aimed to investigate the efficacy of Lasmiditan, a highly selective agonist of the5-hydroxytryptamine 1F (5-HT1F) receptor and a recently approved medication for the treatment of migraine headaches, in ameliorating serotonergic itching. Forty animals were employed in the present study (n = 40). Eight animals were randomly assigned to each of the following study groups (n = 8, in each group): (1) "Normal Saline": This group was given intradermal injections of normal saline (2) "5-HT": The animals were injected with intradermal 5-HT, which was used to induce itching. (3) "Lasmiditan 0.3", "Lasmiditan 1", and "Lasmiditan 3" groups: injected with 5-HT as well as intraperitoneal Lasmiditan at different dose levels (0.3, 1, and 3mg/kg, respectively). Scratching behavior was recorded for 60min, and the skin tissue of three mice was sampled at the end of the behavioral experiment to assess the levels of TLR-4, IL-31, 5-HT1F receptor, CGRP & TRPV4. In the present study, we found that Lasmiditan when administered at 1mg/kg effectively reduced serotonin-induced itching compared to the "5-HT" group (P < 0.0001). Following the administration of Lasmiditan (1mg/kg), the expression levels of the 5-HT1F receptor significantly increased (P < 0.01). Further, the levels of TLR-4, IL-31, CGRP & TRPV4 were substantially reduced upon the administration of Lasmiditan (1mg/kg). We found that Lasmiditan is effective in reducing serotonergic itch in mice through its interaction with the 5-HT1F receptor in the skin tissue of mice.

Direct correlation of MR-DWI and histopathology of Wilms' tumours through a patient-specific 3D-printed cutting guide.

The International Society of Paediatric Oncology-Renal Tumour Study Group (SIOP-RTSG) discourages invasive procedures to determine the histology of paediatric renal neoplasms at diagnosis. Therefore, the histological subtype of Wilms' tumours (WT) is unknown at the start of neoadjuvant chemotherapy. MR-DWI shows potential value as a non-invasive biomarker through apparent diffusion coefficients (ADCs). This study aimed to describe MR characteristics and ADC values of paediatric renal tumours to differentiate subtypes. Children with a renal tumour undergoing surgery within the SIOP-RTSG 2016-UMBRELLA protocol were prospectively included between May 2021 and 2023. In the case of a total nephrectomy, a patient-specific cutting guide based on the neoadjuvant MR was 3D-printed, allowing a correlation between imaging and histopathology. Whole-tumour volumes and ADC values were statistically compared with the Mann-Whitney U-test. Direct correlation on the microscopic slide level was analysed through mixed model analysis. Fifty-nine lesions of 54 patients (58% male, median age 3.0 years (range 0-17.7 years)) were included. Forty-four lesions involved a WT. Stromal type WT showed the lowest median decrease in volume after neoadjuvant chemotherapy (48.1 cm3, range 561.5-(+)332.7 cm3, p = 0.035). On a microscopic slide level (n = 240 slides) after direct correlation through the cutting guide, stromal areas showed a significantly higher median ADC value compared to epithelial and blastemal foci (p < 0.001). With a cut-off value of 1.195 * 10-3 mm2/s, sensitivity, and specificity were 95.2% (95% confidence interval 87.6-98.4%) and 90.5% (95% confidence interval 68.2-98.3%), respectively. Correlation between histopathology and MR-DWI through a patient-specific 3D-printed cutting guide resulted in significant discrimination of stromal type WT from epithelial and blastemal subtypes. Stromal Wilms' tumours could be discriminated from epithelial- and blastemal lesions based on high apparent diffusion coefficient values and limited decrease in volume after neoadjuvant chemotherapy. This may aid in future decision-making, especially concerning discrimination between low- and high-risk neoplasms. MR-DWI shows potential value as a non-invasive biomarker in paediatric renal tumours. The patient-specific cutting guide leads to a correlation between apparent diffusion coefficient values and Wilms' tumour subtype. Stromal areas could be discriminated from epithelial and blastemal foci in Wilms' tumours based on apparent diffusion coefficient values.

Prospective Validation of the Pancreatic Fistula Risk Classification by the International Study Group for Pancreatic Surgery (PARIS trial).

The aim of this study was a prospective validation of the recently established ISGPS pancreas classification as a parenchymal risk classification system for pancreatic fistula after pancreatoduodenectomy. Postoperative pancreatic fistula (POPF) is the major driver for complications after partial pancreatoduodenectomy (PD). Recently, the International Study Group for Pancreatic Surgery (ISGPS) published a pancreas classification containing the parameters main pancreatic duct diameter (MPD) and pancreatic texture to help assess the risk of POPF development following pancreatoduodenectomy. From January 2020 to July 2021, 271 patients receiving elective PD were included after informed consent. The postoperative course was documented prospectively up to postoperative day 30. Among the pancreas characteristics, MPD and pancreatic texture were assessed intraoperatively at the pancreatic resection margin and the pancreatic glands were assigned to one of the four pancreas classes according to the ISGPS (A to D). The primary endpoint was POPF according to the updated ISGPS definition. Secondary endpoints comprised other post-PD morbidity and mortality. Of 271 patients, 264 had available data according to the ISGPS pancreas classification. Of those, 78 were assigned to class A (30%), 53 to class B (20%), 50 to class C (19%) and 83 to class D (31%). POPF occurred in 54 of 271 patients (19.9%). The 30-day mortality was 7/271 (2.6%), with 6/7 having developed POPF (86%). POPF rates within the classes A, B, C and D were 9.0%, 11.3%, 20.0% and 37.4%, respectively (P<0.001). In the univariable regression analysis, only patients in pancreas class D demonstrated a significantly higher risk for POPF when compared to class A (OR 6.05, 95%-CI: 2.6-15.9, P<0.001). In the multivariable regression model, patients in class D had a significantly higher risk for POPF compared to class A (OR 3.45, 95%-CI: 1.15-11.3, P=0.032). The model comprised Body Mass Index, surgery duration, microscopic fibrosis and the ISGPS pancreas classification, demonstrating an AUC-value of approximately 0.82 when tested on the PARIS dataset. This prospective trial shows that the ISGPS pancreas classification is valid. Patients in risk class D are prone to POPF independently of other factors. Therefore, all future publications on pancreatic surgery should report the risk class according to the ISGPS pancreas classification to allow for a better comparison of reported cohorts.

Clinical and Genomic Perspective of SARS CoV-2 Infection in Liver Disease Patients: A Single-Centre Retrospective Study.

The limited literature on the clinical course of COVID-19 among patients with underlying liver disease (LD) is available from India. The present study aimed to evaluate the clinical and mutational profile of SARS-CoV-2 among LD cases. This was a retrospective study including admitted LD cases in whom SARS-CoV-2 RT-PCR testing was performed. Complete demographic and clinical details were retrieved from Hospital Information System. Detailed mutational analysis was performed by comparing LD COVID-19 positive study group, i.e. LD-CoV(+) with COVID-19 positive outpatients without any underlying LD as control, i.e. NLD-CoV(+). Out of 232 enrolled LD cases, 137 (59.1%) were LD-CoV(+). LD cases with existing co-morbidities were affected more (P = 0.002) and had 2.29 times (OR 2.29, CI 95%, 1.25-4.29) higher odds of succumbing to COVID-19 (P = 0.006). On multivariate regression analysis, ascites (P = 0.05), severe COVID-19 pneumonia (P = 0.046), and an increased levels of bilirubin (P = 0.005) and alkaline phosphatase (P = 0.003) were found to be associated with adverse outcome in LD-CoV(+).On mutational analysis, we found certain differences between LD- and NLD-CoV(+) infected with Delta [LD- and NLD-CoV (+ /D)] and Omicron [LD- and NLD-CoV(+/O)]. More mutations were shared between LD- and NLD-CoV(+/O) compared to LD- and NLD-CoV(+/D). There were differences in prevalence of indel mutations specific to LD-CoV ( +) for both Delta and Omicron. Moreover, we also reported an interesting genic bias between LD- and NLD-CoV( +) in harbouring deleterious/tolerated mutations. To conclude, LD cases with comorbidities were affected more and had higher odds of mortality due to COVID-19. The definite difference between LD- and NLD-CoV(+) groups with respect to frequency of harboured mutations and an inherent genic bias between them is of noteworthy importance.

Comparative efficacy of bilateral mesh sacrospinous ligament suspension versus laparoscopic sacrocolpopexy in patients with metroptosis

This study assesses the efficacy of bilateral mesh sacrospinous ligament suspension (MSSLS) compared to laparoscopic sacrocolpopexy (LSC) in patients with uterine prolapse. Ninety-eight patients with uterine prolapse were evaluated at our hospital from January 2021 to January 2023. Patients were equally divided into two groups: the study group (undergoing MSSLS) and the control group (undergoing LSC) using a random number table. Various parameters including operation time, bleeding volume, indwelling catheter time, exhaust time, hospital stay, pelvic organ prolapse stage, postoperative recurrence rate, pain severity, quality of life, pelvic floor function, impact on sexual life, complications, and recurrence rate were recorded. The study group showed significant reductions in operation time, bleeding volume, indwelling catheter time, exhaust time, and hospital stay compared to the control group (P < 0.05). There were no significant differences in Aa, Ba, Ap, Bp, and C between the two groups before surgery (P > 0.05), but six months postoperatively, these indexes were significantly lower in the study group (P < 0.05). Pain severity did not differ significantly between the two groups before surgery (P > 0.05), but was significantly lower in the study group six months postoperatively (P < 0.05). Quality of life, pelvic floor function, and sexual life quality did not significantly differ before surgery, at 6 months, and at 12 months postoperatively (P > 0.05). All patients were followed up for 12–14 months, with an average follow-up time of (13.02 ± 1.36) months. The incidence of complications was significantly lower in the study group (P < 0.05), but there were no recurrences in either group, thus the difference was not statistically significant (P > 0.05). MSSLS emerges as a safe and efficacious treatment for uterine prolapse, notably reducing both complications and recurrence rates, rendering it suitable for broad clinical application.

The impact of antiplatelet and anticoagulant medications on early implant failure following sinus floor augmentation: A retrospective cohort analysis.

The effect of antiplatelet and anticoagulant medications on the outcomes of sinus floor augmentation remains unclear. This retrospective cohort study analyzed data from electronic medical records of consecutive patients undergoing sinus floor augmentation at a single medical center. Patients were categorized into three categories: patients under antiplatelet medications, patients under anticoagulation medications, and healthy individuals. Data collected included tobacco smoking, residual alveolar bone height, timing of implant placement, materials used, vertical bone gain, early implant failure (EIF), and complications such as Schneiderian membrane perforation and postoperative bleeding. Multivariable analysis was performed to assess risk factors for EIF. Statistical significance was considered below 5%. Among 110 patients with 305 implants, EIF occurred in 10% of patients and 4.65% of implants. No significant difference in postoperative bleeding or EIF was found between study groups. Univariate and multivariable analyses highlighted tobacco smoking (odds ratio [OR] = 7.92), lower residual alveolar ridge height (OR = 0.81), and staged implant placement (OR = 4.64) as significant EIF risk factors in this cohort. Anticoagulant and antiplatelet therapies do not significantly elevate the risk of EIF or postoperative bleeding following sinus floor augmentation. Tobacco smoking, residual alveolar ridge height and staged sinus floor augmentation were risk factors for EIF in patients using antiplatelet or anticoagulation medications undergoing sinus floor augmentation.

Thrombocytopenia in Plasmodium vivax Malaria: A Report from a Sub-zonal Hospital in Western Rajasthan

Abstract Background: Malaria continues to be a major public health problem in India. Vivax malaria is being increasingly seen with thrombocytopenia. The reported prevalence of the same has been extremely variable and its significance is not well established. This study was conducted to ascertain the prevalence and severity of thrombocytopenia in vivax malaria and assess the outcome of cases with severe thrombocytopenia. A secondary objective was to compare the clinical and laboratory profile of cases of vivax malaria with falciparum malaria and mixed infection. Materials and Methods: This hospital-based prospective study was carried out in the department of general medicine at a sub-zonal hospital in Western Rajasthan in the year 2022. Consecutive febrile patients with a diagnosis of malaria were included in the study after ruling out coexistent alternate infections. Results: A total of 396 cases were enrolled. Ninety-nine percent of patients were male. The mean age of the study group was 32.1 years. A total of 328 (90.8%) out of 361 vivax malaria cases had thrombocytopenia (platelet count &lt;150 × 103 μL) with 26.5% having severe thrombocytopenia (platelet count &lt;50 × 103 μL). The mean defervescence duration was 44.4 h in vivax malaria. 3.4% of severe vivax malaria cases required intensive care unit care due to hypotension, respiratory distress, and multiorgan dysfunction, and none of them had any bleeding manifestations. All cases recovered well after standard treatment. There was a significant statistical difference between the mean platelet count among the three types of malaria: vivax, falciparum, and mixed (vivax + falciparum infections) (P = 0.03). Similarly, on applying Chi-square test, there was a significant difference in severe thrombocytopenia across the groups (P = 0.01). Conclusion: There is a high prevalence of thrombocytopenia in vivax malaria including severe thrombocytopenia. In the majority of cases, this thrombocytopenia does not result in any adverse event, and cases respond well to conventional treatment. Clinicians need to be aware of the extent and severity of thrombocytopenia in vivax malaria and rule out this treatable condition in endemic areas with a high prevalence of other coexistent infections causing thrombocytopenia.

Effects of high-quality neurosurgical nursing care on improving clinical nursing quality.

With continuous advancements in medical technology, neurosurgical nursing is constantly developing and improving to provide higher-quality nursing services. To explore the effects of different types of high-quality nursing care on clinical nursing quality and patient satisfaction in neurosurgical nursing. Eighty patients who received neurosurgical treatment in the Affiliated Hospital of Southwest Medical University from June to December 2020 were selected as study participants and categorised into study and control groups. The study group comprised 40 patients who received 4 different types of high-quality nursing care, whereas the control group comprised 40 patients who received conventional nursing care. After a specific period, nursing satisfaction levels and adverse event and complication rates were compared between the two groups. Satisfaction with high-quality care was higher than that with conventional care, and high-quality health services and regional services showed the highest satisfaction levels, with an average score of 12 on the Glasgow scale. The satisfaction levels of the study and control groups were 75% and 57%, respectively, with a statistically significant difference (t = 7.314, P < 0.05). During the nursing period, the adverse event and complication rates were the highest in patients with level III pathology grade and those who underwent neurosurgery (40.02% and 85.93%, respectively), and the difference was statistically significant. In neurosurgical nursing, employing appropriate high-quality nursing methods can effectively reduce adverse event and complication rates in patients, thereby improving the quality of nursing care and increasing clinical nursing value.

The impact of anastomotic leakage characteristics on the occurrence of anastomotic stenosis after colorectal resection, a retrospective cohort study.

Anastomotic stenosis (AS) is a common complication after colorectal resection. However, the predisposing factors for stricture formation are not fully understood. Previous studies have shown anastomotic leakage (AL) to be a risk factor for the occurrence of AS. Therefore, we aim to investigate the impact of anastomotic leakage characteristics on the occurrence of anastomotic stenosis after colorectal resection. Consecutive patients with AL following elective, sphincter preserving, colorectal resection, with or without diversion ostomy, between January 2009 and March 2023 were identified from a prospectively collected database. The characteristics of the anastomotic leakage, patient baseline and operative characteristics as well as the postoperative outcomes were analyzed using univariate and multivariate logistic regression to identify factors associated with the occurrence of post-leakage AS. A total of 129 patients developed AL and met the inclusion criteria. Among these, 28 (21.7%) patients were diagnosed with post-leakage AS. There was a significantly higher frequency of patients with neoadjuvant radiotherapy (18% vs 3%; p = .026) and hand-sewn anastomoses (39% vs 17%; p = .011) within the AS group. Furthermore, the extent of the anastomotic defect was significantly higher in the AS group compared with the non-AS group (50%, IQR 27-71 vs. 20%, IQR 9-40, p = 0.011). Similar findings were observed between the study groups regarding age, sex, BMI, ASA score, medical comorbidities, diagnosis, surgical procedure, surgical approach (open vs. minimally invasive), and anastomotic fashioning (side-to-end vs. end-to-end). On multivariate analysis, the extent of the anastomotic defect (OR 1.01; 95% CI 1.00-1.03; p = 0.034) and hand-sewn anastomoses (OR 2.68; 95% CI 1.01-6.98; p = 0.043) were confirmed as independent risk factors for post-leakage AS. No correlation could be observed between the occurrence of post-leakage AS and the ISREC grading of AL, the anastomotic height or the management of AL. Time to ostomy reversal was significantly longer in the AS group (202d, IQR 169-275 vs. 318d IQR 192-416, p = 0.014). The extent of the anastomotic defect and hand-sewn anastomoses were confirmed as independent risk factors for the occurrence of post-leakage AS. No correlation could be observed between the ISREC grading of AL, the anastomotic height or AL management, and the occurrence of post-leakage AS.

Corneal aberrations are associated with low-energy meniscus injuries

BackgroundVisual impairment can cause balance problems. Therefore, visual impairment caused by an increase in corneal deviations can lead to sudden and unstable loads in the lower extremities. We aimed to investigate the possible relationship between low-energy meniscal injuries and corneal structural measures.MethodsThis prospective, observational study included individuals aged between 18–40 years with a normal body-mass index. The study group consisted of 54 patients with grade 2 or 3 meniscus injuries after low-energy activity. The control group consisted of 54 healthy individuals without any complaints in the knee joint. The corneal parameters of all participants were evaluated with a Scheimpflug corneal topography and specular microscopy device. Simulated keratometry (SimK), minimum central corneal thickness (MCCT), cylindrical diopter (ClyD), corneal volume (CVol) spheric aberrations (SphAbb), high-order aberration (HOA), coma values, and endothelial parameters were recorded.ResultsThe research and control groups were similar in terms of age, body mass index, and gender distribution. There was no significant difference between the groups in the corneal SimK and CylD, parameters. However, HOA, Coma, SphAbb, and cell variability (Cv) values were significantly higher in the study group, and contrarily MCCT, CVol, and endothelial count (Cd) values were significantly lower.ConclusionsOur findings suggest that individuals with relatively lower MCCT values tend to develop meniscal damage after low-energy activity. Hence, the loss of corneal strength in these patients may be a sign of possible weakness in the meniscus. The HOA value above 0.26, the coma value above 0.16, and the SphAbb value above 0.1 may significantly increase the possible meniscus injury.

Effect of bivalirudin on myocardial microcirculation and adverse events after interventional therapy in older patients with acute coronary syndrome.

Bivalirudin, a direct thrombin inhibitor, is used in anticoagulation therapies as a substitute for heparin, especially during cardiovascular procedures such as percutaneous coronary intervention. To explore the effect of bivalirudin on myocardial microcirculation following an intervention and its influence on adverse cardiac events in elderly patients with acute coronary syndrome (ACS). In total, 165 patients diagnosed with acute myocardial at our hospital between June 2020 and June 2022 were enrolled in this study. From June 2020 to June 2022, elderly patients with ACS with complete data were selected and treated with interventional therapy. The study cohort was randomly divided into a study group (n = 80, administered bivalirudin) and a control group (n = 85, administered unfractionated heparin). Over a 6-mo follow-up period, differences in emergency processing times, including coronary intervention, cardiac function indicators, occurrence of cardiovascular events, and recurrence rates, were analyzed. Significant differences were observed between the study cohorts, with the observation group showing shorter emergency process times across all stages: Emergency classification; diagnostic testing; implementation of coronary intervention; and conclusion of emergency treatment (P < 0.05). Furthermore, the left ventricular ejection fraction in the observation group was significantly higher (P < 0.05), and the creatine kinase-MB and New York Heart Association scores were notably lower than those in the control group (P < 0.05). In elderly patients receiving interventional therapy for ACS, bivalirudin administration led to increased activated clotting time achievement rates, enhanced myocardial reperfusion, and reduced incidence of bleeding complications and adverse cardiac events.

A comparative study of the outcome of unilateral versus bilateral internal anal sphincterotomy in treatment of chronic anal fissure

Background: Gold standard treatment for chronic anal fissure is lateral internal sphincterotomy. Bilateral internal sphincterotomy (BIS) as a treatment option for chronic anal fissure has not been evaluated. Aims and Objectives: The aims and objectives of the study are to compare the efficacy of unilateral versus bilateral internal anal sphincterotomy in treatment of chronic anal fissure. Materials and Methods: Study design: A prospective randomized comparative study. Study area: Patients coming to General Surgery outpatient department at College of Medicine and Sagore Dutta Hospital with chronic anal fissure. Study period: July 2022 to December 2023 (18 months). Sample Size: 100 patients. Study Group: Group A=Patients who had undergone unilateral internal sphincterotomy (UIS)=50 patients and Group B=Patients who had undergone BIS=50 patients. Results: 2 (4%) patients in Group A and 3 (6%) patients in Group B developed incontinence for flatus postoperatively. No patients in either group developed incontinence for stools. The Mean Fissure Healing Time (Mean±SD) (Weeks) post-sphincterotomy was 4.32±0.91339 in Group A and 2.66±0.65807 in Group B. There were 6 cases of recurrence in the unilateral sphincterotomy group. Second surgery was needed in 4 patients who underwent unilateral sphincterotomy. Conclusion: As compared to UIS, BIS results in a faster healing of chronic anal fissure, with no increase in incontinence, decreased pain score, and less recurrence rates.

Posterior Cruciate Buckling Angle Variations Are Associated with Different Patterns of Medial Meniscus Tears in Anterior-Cruciate-Deficient Knees: Results of a Prospective Comparative Magnetic Imaging Resonance Study

Background: The diagnosis of anterior cruciate ligament (ACL) tear relies on clinical evaluation and magnetic resonance imaging (MRI). Direct and indirect signs of ACL tear have been described with MRI evaluation. Posterior cruciate ligament (PCL) buckling has been described as an indirect radiographic sign of an ACL tear. Purpose: The aim of the present study was to assess the variations in PCL buckling angles in patients with ACL tears and in patients with isolated lesions in the posterior horn of the medial meniscus. In addition, the influence of different patterns of medial meniscus tears in ACL-deficient knees was investigated. Finally, the influences of risk factors such as tibial slope, delay from injury to surgery, absence of medial meniscus tear, degree of Lachman and pivot shift testing were also assessed. Study design: This was a cohort study. Methods: A total of 154 patients (78 in the group with ACL tear and 76 in the control group) were assessed with MRI and lateral weight-bearing X-ray to assess PCL buckling angle and tibial slope by two independent observers. The presence of a medial meniscus bucket handle or ramp lesion of the medial meniscus was assessed and recorded at the time of surgery. Results: PCL buckling angle measurement was highly reliable, with an ICC of 0.866 and 0.894, respectively, in the study group and the control group for interobserver reliability. The intrarater reliability was found to be high in PCL buckling angle for the study group [ICC = 0.955] and the control group [ICC = 0.943]. The mean angle in patients with ACL tear was 110.7 ± 15.2° and 115.3 ± 16.2° (for the two examiners) and 111.4 ± 12° and 114 ± 14.5° (for the two examiners) in patients with an intact, healthy ACL. An association emerged between bucket handle tears of the medial meniscus (p = 0.010) and a decreased PCL buckling angle and between ramp lesions of the medial meniscus and increased PCL buckling angle both (p = 0.024). Conclusions: Good inter- and intraobserver reliability for the measurement of the PCL buckling angle was observed. Increased PCL buckling angle values were observed in patients with concomitant ACL and bucket handle tears of the medial meniscus, while decreased angle values were observed in those who had ACL tear and ramp lesion of the medial meniscus. No statistically significant difference in the PCL buckling angle emerged between patients with ACL tears and those who had a healthy, intact ACL.

Systematic implementation of cardiopulmonary ultrasound imaging to optimize management of acute decompensated heart failure

BackgroundHeart failure (HF) poses a major health problem, where frequent HF rehospitalizations (HFH) heavily burden national health systems. HFH are predominantly linked to inadequate decongestion before discharge. It is uncertain if systematic implementation of cardio-pulmonary ultra-sound imaging (CPUSI) to standard HF management can improve outcomes and reduce HFH.ResultsThis study recruited 50 patients admitted with acute decompensated heart failure (ADHF). Besides the conventional daily assessment, CPUSI was systematically performed to guide treatment decisions, focusing on ventricular filling pressure and 8-zone lung ultrasound (LUS) score. On-admission and predischarge LUS scores were correlated to clinical outcomes. The mean age of the study group was 55.7 ± 10.59 years, with predominance of male gender. Supplementing clinical judgment, CPUSI modified therapeutic strategy in 57 out of 241 assessments (24%), improving patients’ care. Besides its value in guiding therapeutic decisions, the LUS score on admission had a significant positive correlation to the length of ICU stay and the total hospitalization length. Also, LUS score > 12 at discharge predicted 90-day HFH with sensitivity and specificity of 100% and 98%, respectively.ConclusionsSystematic CPUSI can improve HF management by complementing the often challenging judgment of pulmonary congestion. Adding periodic evaluation of ventricular filling pressures and LUS scores to clinical assessment can optimize treatment decisions and improve patient care. LUS score was a significant predictor for in-hospital and post-discharge clinical outcomes.Graphical abstract

Empowering mind-body wellness: effect of bundling seated exercises and psychoeducational rehabilitation using the teach-back approach on fatigue and coping of women postmastectomy

BackgroundBeing diagnosed with Breast Cancer (BC) is a crisis that throws the patient’s life out of balance. Cancer-related fatigue is a debilitating sign experienced by women during and after BC treatment. Regular physical exercise may help mitigate patients’ fatigue, enhance coping abilities, improve their quality of life, and overall well-being. In parallel, psychological interventions are geared toward normalizing the lived painful experiences among oncology patients.Objectiveto examine the effect of bundling seated exercises and psychoeducational rehabilitation using the teach-back approach on fatigue and coping of women postmastectomy.MethodsA quasi-experimental study was conducted in the Oncology Surgical Department and chemotherapy unit at the Alexandria Main University Hospital, Egypt. A total of 60 women were randomly allocated to either to the study or the control groups. Women in the study group practiced seated exercises and psychological rehabilitation interventions, including mindfulness breathing, problem-solving training, cognitive reframing technique, and thought stopping while the control group received the routine care.ResultsThe study revealed a significant decline in the fatigue mean scores among participants in the intervention group from 136.10 ± 27.76 to 98.43 ± 25.99 (p < 0.001). Similarly, there was a significant decrease in the patients’ mean scores of maladaptive coping, helplessness/ hopelessness (p = 0.014), and anxious preoccupation (p = 0.008). In contrast, there is a noticeable increment in the scores of adaptive coping, such as fighting spirit (p = 0.012), cognitive avoidance (p = 0.002), and fatalism (p = 0.009).ConclusionBundling seated exercises and psychological rehabilitation interventions using the teach-back approach have been proven to be simple and inexpensive non-pharmacological methods of reducing cancer-related fatigue and improving coping skills among women post-mastectomy.Trial registration numberNCT06360276, ClinicalTrails.gov, Retrospectively registered (April 8th, 2024), URL of trial registry record: https://clinicaltrials.gov/ct2/show/NCT06360276.

Treatment Trends and Epidemiologic Changes in Acetabular Fracture Management over the Course of 10 Years: An Analysis Based on 2853 Patients as Treated by the German Pelvic Multicenter Study Group

Background/Objectives: Acetabular fractures, traditionally linked to high-impact trauma in younger adults, are increasingly observed in the elderly due to falls and poor bone quality. This demographic shift necessitates updated treatment approaches. This study analyzes demographic trends and treatment evolution over a decade using the German pelvic fracture registry. Methods: Data on acetabular fractures were analyzed from the German pelvic fracture registry of the German Trauma Society. Parameters included classification, demographics, treatment methods, and surgical details. Trends were assessed by grouping patients based on treatment intervals and age, comparing treatment methods, surgical approaches, and reduction quality across these groups, considering fracture types and treatment volume. Results: The study included 2853 unilateral acetabular fractures with a mean patient age of 61.5 years, showing an increasing age trend. A shift from simple to complex fractures involving the anterior acetabular column was observed. Operative treatment was performed in 62.5% of cases, more common in non-geriatric patients and those with posterior column involvement. The use of anterior intrapelvic approaches increased over time, replacing the Ilioinguinal extrapelvic approach. Anatomical reduction was achieved in 47.4% of cases, with 31.7% having imperfect reductions and 20.9% poor reductions. High-volume centers had significantly better reduction outcomes, particularly for simple fractures. Geriatric patients exhibited worse reduction quality compared to younger patients. In-hospital mortality was stable at 3.3%. Conclusions: The study highlights a demographic shift towards an older patient population, leading to more complex fracture patterns. Despite advancements in surgical techniques and new implant technologies, these demographic changes have resulted in lower reduction quality for complex fractures. Emphasis is placed on careful patient selection for reconstructive surgery or endoprosthetic replacement to ensure high-quality outcomes.

Protective effect of modified lange "second position" for developing avascular necrosis following closed reduction for developmental dysplasia of the hip.

Developmental Dysplasia of the Hip (DDH) is a condition affecting hip joint development in children, presenting multiple manifestations. Immobilization methods to ensure hip concentricity, such as the human position and modified Lange position, vary in effectiveness and risks, especially avascular necrosis. The purpose of this study was to identify whether closed reduction (CR), with two different immobilization techniques, is effective in avoiding complications such as residual hip dysplasia (RHD), re-dislocation, and Avascular Necrosis (AVN). A total of 66 patients with DDH (84 hips) were treated with two different techniques of immobilization (groups A and B); the mean age at the time of reduction was 8 (6-13) months. The rates of RHD, Re-dislocation, and AVN were determined with a minimum follow-up of 48 months in both techniques. The Chi-square analysis conducted across the study groups unveiled that patients in Group B demonstrated a protective effect against AVN compared to those in Group A (OR: 0.248, 95% CI: 0.072-0.847, p = 0.026). However, no statistically significant differences were found between the groups concerning RHD (p = 0.563) and re-dislocation (p = 0.909). After the initial Human Position immobilization, the second cast with the modified Lange "second position" demonstrated a protective effect compared with maintaining the Human Position immobilization throughout the immobilization period, reducing the likelihood of AVN development in patients undergoing closed reduction for developmental dysplasia of the hip.
