Methods:
Patients with severe kyphoscoliosis having coronal Cobb angle >90° were applied with modified halo-pelvic Ilizarov distraction assembly preoperatively. The modified assembly consisted of a pelvic component and halo ring, and distraction was given at the rate of 2–3 mm/day for 6–12 weeks. Complete clinical assessments along with pulmonary function tests were performed, and scoliosis series X-ray images were assessed for coronal and sagittal Cobb angle and other spinopelvic parameters before applying the assembly and during 2 years of follow-up.
Results:
Thirty-four patients (age, 9–27 years; male/female ratio of 18:16) were included. The coronal and sagittal Cobb angles were 116°±16.2° and 84°±28.3°, respectively. Correction rates obtained through modified halo-pelvic assembly were nearly 52% (p=0.001) in coronal and 40% (p=0.001) in sagittal Cobb angles, with improvement in height (p=0.001). Apical vertebral translation and coronal balance were also improved significantly (p=0.001). Further improvements in all the parameters were obtained after definitive surgery, with improvements in the forced expiratory volume in 1 second (p =0.002) and forced vital capacity (p=0.001).
Conclusions
Our modified halo-pelvic Ilizarov distraction assembly can achieve good correction in severe spinal deformities without significant risk to neurology, has fewer complications, and promotes good patient compliance.

Atrial fibrillation (AF) is a prevalent cardiac arrhythmia affecting millions of individuals worldwide and posing significant challenges to healthcare systems. The growing body of research has uncovered sex-related differences in AF pathophysiology, including the role of fatty acid-binding protein 4 (FABP4) and leptin as potential biomarkers. FABP4 and leptin, key adipokines involved in cardiovascular health, have been linked to inflammation, oxidative stress, and endothelial dysfunction, all of which may contribute to AF development. These adipokines exhibit sex-specific differences in their concentrations, with females generally showing higher FABP4 levels and males displaying distinct leptin profiles. Furthermore, hormonal influences, particularly estrogen, and testosterone, play significant roles in shaping AF risk and atrial remodeling. Estrogen is associated with cardioprotective effects, while testosterone may exert proarrhythmic effects. Understanding these sex-specific mechanisms could lead to more tailored and effective clinical management of AF. The future of AF research holds promise for precision medicine, novel therapeutic targets, artificial intelligence integration, and personalized care approaches. Emphasizing patient-centered care, telemedicine, and multidisciplinary collaboration can further enhance AF management and improve patient outcomes. In conclusion, recognizing and addressing sex-related factors in AF pathophysiology offer opportunities for gender-responsive interventions and advancements in AF management. Implementing these insights may pave the way for targeted therapies and improved quality of life for individuals affected by AF.

Objectives:
Postmenopausal females often experience genitourinary symptoms like vulvovaginal dryness due to estrogen decline.Hormone replacement therapy is effective in alleviating vaginal atrophy and genitourinary syndrome in this population. Evaluate local estrogen’s safety and effectiveness for alleviating postmenopausal vaginal symptoms, including endometrial thickness, dyspareunia, vaginal pH, and dryness.
Methods:
We searched Google Scholar, Cochrane Library, ClinicalTrial.Gov, PubMed, and ScienceDirect databases until July 2023. All randomized controlled trials (RCTs) linking intravaginal estrogen supplementation to vaginal atrophy or vaginitis were included. The risk of bias was evaluated with RoB 2, and publication bias was assessed using Egger and Beggs analysis.
Results:
All evidence pertains to females. Eighteen studies (n = 4,723) compared estrogen with placebo. Patients using estrogen showed a significant increase in superficial cells (mean differences [MD]: 19.28; 95% confidence intervals [CI]: 13.40 to 25.16; I2 = 90%; P < 0.00001) and a decrease in parabasal cells (MD: –24.85; 95% CI: –32.96 to –16.73; I2 = 92%; P < 0.00001). Vaginal pH and dyspareunia significantly reduced in estrogen users (MD: –0.94; 95% CI: –1.05 to –0.84; I2 = 96%) and (MD: –0.52; 95% CI: –0.63 to –0.41; I2 = 99%), respectively. Estrogen did not significantly affect vaginal dryness (MD: –0.04; 95% CI: –0.18 to 0.11; I2 = 88%). Adverse events like vulvovaginal pruritis, mycotic infection, and urinary tract infection were reported, but the association was insignificant (risk ratio: 0.95; 95% CI: 0.88 to 1.02; I2 = 0%).
Conclusions
Our meta-analysis of 18 RCTs suggests promising potential for intravaginal estrogen therapy in alleviating vaginal atrophy and vaginitis in postmenopausal females.

Objective:
The study examined the efficacy of various generations of cephalosporins against biofilms developed by pathogenic S. aureus and E. coli.
Methods:
The development of biofilms by both bacteria was assessed using petri-plate and microplate methods. Biofilm hydrolysis and inhibition were tested using first to fourth generations of cephalosporins, and the effects were analyzed by crystal violet staining and phase contrast microscopy.
Results:
Both bacterial strains exhibited well-developed biofilms in petri-plate and microplate assays. Cefradine (first generation) showed 76.78% hydrolysis of S. aureus biofilm, while significant hydrolysis (59.86%) of E. coli biofilm was observed by cefipime (fourth generation). Similarly, cefuroxime, cefadroxil, cefepime, and cefradine caused 78.8%, 71.63%, 70.63%, and 70.51% inhibition of the S. aureus biofilms, respectively. In the case of E. coli, maximum biofilm inhibition (66.47%) was again shown by cefepime. All generations of cephalosporins were more effective against S. aureus than E. coli, which was confirmed by phase contrast microscopy.
Conclusions
and Relevance: Cephalosporins exhibit dual capabilities of hydrolyzing and inhibiting S. aureus and E. coli biofilms. First-generation cephalosporins exhibited the highest inhibitory activity against S. aureus, while the third and fourth generations significantly inhibited E. coli biofilms. This study highlights the importance of tailored antibiotic strategies based on the biofilm characteristics of specific bacterial strains.

A plethora of paraneoplastic syndromes have been reported as remote effects of colorectal carcinoma (CRC). However, there is a dearth of data pertaining to the association of this cancer with demyelinating neuropathies. Herein, we describe the case of a young woman diagnosed with chronic inflammatory demyelinating polyneuropathy (CIDP). Treatment with intravenous immunoglobulins and prednisone did not improve her condition, and her neurological symptoms worsened. Subsequently, she was readmitted with exertional dyspnea, lightheadedness, malaise, and black stools. Colonoscopy revealed a necrotic mass in the ascending colon, which directly invaded the second part of the duodenum. Pathologic results confirmed the diagnosis of locally advanced CRC. Upon surgical resection of the cancer, her CIDP showed dramatic resolution without any additional therapy. Patients with CRC may develop CIDP as a type of paraneoplastic syndrome. Clinicians should remain cognizant of this potential association, as it is of paramount importance for the necessary holistic clinical management.

Vibrio harveyi belongs to the Vibrio genus that causes vibriosis in marine and aquatic fish species through double-stranded DNA virus replication. In humans, around 12 Vibrio species can cause gastroenteritis (gastrointestinal illness). A large amount of virus particles can be found in the cytoplasm of infected cells, which may cause death. Despite these devastating complications, there is still no cure or vaccine for the virus. As a result, we used an immunoinformatics approach to develop a multi-epitope vaccine against most pathogenic hemolysin gene of V. harveyi. The immunodominant T- and B-cell epitopes were identified using the hemolysin protein. We developed a vaccine employing three possible epitopes: cytotoxic T-lymphocytes, helper T-lymphocytes, and linear B-lymphocyte epitopes, after thorough testing. The vaccine was developed to be antigenic, immunogenic, and non-allergenic, as well as having a better solubility. Molecular dynamics simulation revealed significant structural stiffness and binding stability. In addition, the immunological simulation generated by computer revealed that the vaccination might elicit immune reactions in the actual life after injection. Finally, using Escherichia coli K12 as a model, codon optimization yielded ideal GC content and a higher codon adaptation index value, which was then included in the cloning vector pET2+ (a). Altogether, our experiment implies that the proposed peptide vaccine might be a good option for vibriosis prophylaxis.
