The most commonly described symptom described as not at all by females was hearing words that others do not hear. There was no statistical difference in mental well-being between males and females. Older participants (>40 years old) had better mental well-being in comparison to their younger counterparts. Conclusion During the fallout of the coronavirus disease 2019 (COVID-19) pandemic, much attention and resources were allocated toward the physical aspect of the pandemic, yet the psychological implications must not be understated. Multiple variables, such as age, marital status, and unemployment, may impact the mental well-being of the population and must be further assessed.Background Metabolic syndrome (syndrome X) is the name for a group of risk factors that raises your risk for heart disease and other health problems, such as diabetes and stroke. Dilatation of blood vessels following stress is a function of vasodilators produced by the endothelium. Flow-mediated vasodilation assesses endothelial function. In the case of endothelial dysfunction, flow-mediated vasodilation is impaired, resulting in decreased or even absence of vasodilation following stress. The easy availability of ultrasound machines nowadays and the non-invasive nature of the test make this a practical test for assessing endothelial dysfunction and the risk of cardiovascular diseases. Various studies have confirmed the presence of impaired flow-mediated vasodilation in patients with coronary artery disease. However, the presence of impaired flow-mediated vasodilation in individuals with risk factors but no cardiovascular diseases can prove that this can be used to predict individuals at risk. This study triesdothelial dysfunction in NAFLD, as shown by the decrease in flow-mediated vasodilation when compared with normal liver.Most osteoporotic vertebral fractures (OVFs) are treated conservatively, but surgery is often indicated for residual pain, neuropathy, or severe deformity. OVFs tend to develop in elderly patients, so less invasive surgery is desirable. Surgery is mainly performed to stabilize the fractured vertebral body. Percutaneous cement augmentation, such as via balloon kyphoplasty (BKP), has produced satisfactory results as a surgical method for managing OVFs. Posterior fixation with implants is often performed with or without cement augmentation when stronger fixation is considered necessary for OVFs with local kyphosis and angular instability. Pedicle screws (PSs) are widely used as an implant for posterior fixation, but given the risk of backing out in bones with severe osteoporosis, several measures have been taken to increase the strength such as by adding hooks. In cases of osteoporosis, hooks that can use cortical bone as an anchor are considered more useful than PS but are rarely used in minimally invasive surgery. We developed a minimally invasive posterior hook stabilization approach to directly stabilize the posterior spinal components as a new augmentation method for BKP and applied it to four cases of thoracolumbar OVF with neurological symptoms. WAY-262611 The operation time was about 60 minutes, including BKP, and the estimated blood loss was about 10 ml. link2 No postoperative implant problems occurred, and in all cases, neurological symptoms, such as buttocks and leg pain, were alleviated at an early stage after surgery. link3 One patient had a postoperative adjacent vertebral body fracture that was conservatively treatable. Minimally invasive posterior hook stabilization, which we developed as a way of augmenting BKP, was considered useful for managing vertebral body fractures of the thoracolumbar spine with local kyphosis and angular instability.Hypoventilation syndrome is defined as a decrease in alveolar ventilation leading to hypercapnia (PaCO2 > 35-45 mmHg) and hypoxemia. There are multiple causes of hypoventilation syndrome described in the literature, of which central and obesity-related causes are more prevalent. Other causes such as neuromuscular disorders and chest wall deformities are relatively less common. Multiple defects in the normal functioning of the respiratory function are implicated in the pathophysiological mechanism of hypoventilation syndrome, such as a hypoactive central ventilatory drive, decreased airway function, ventilation-perfusion mismatch, defective pulmonary mechanics, and respiratory muscle fatigue. Patients often present with dyspnea, headache, lethargy, repeated pulmonary infections, hypoxia that usually improves with low flow oxygen, and hypercapnia that may alter mental function. Nocturnal or diurnal assisted mechanical ventilation is proven to be an effective therapy for patients suffering hypoventilation syndromes. We describe a case of a 47-year-old woman with hypoventilation syndrome resulting from a rare chest wall deformity with inward protrusion of the costochondral junction of the ribs with ossification of the costal cartilage on CT who presented with dyspnea and hypercapnia.Abdominal liposarcoma is most often located in the retroperitoneum. Small bowel mesentery is a rare site of liposarcoma. Dedifferentiated liposarcoma (DDLS) is a rare variant of mesenteric liposarcoma with only 12 cases reported in the literature. DDLS has a worse prognosis compared to a well-differentiated liposarcoma. Here, we present a case of giant liposarcoma located in the jejunal mesentery diagnosed on the contrast-enhanced computed tomography of the abdomen. The patient underwent complete surgical excision with uneventful postoperative recovery. DDLS was confirmed on histopathological examination of the resected specimen. The patient is currently receiving adjuvant therapy with doxorubicin and ifosfamide in view of close resection margin, mitotic rate and high rate of recurrence.Isolation of Shigella in the bloodstream is a rare sequela of Shigella infections. Shigellemia typically occurs in patients with immature immune responses or in immunocompromised adults. Herein, we present a case of shigellemia in a 40-year-old male who presented with diabetic ketoacidosis (DKA), severe diarrhea, hypovolemic hyponatremia, and altered mental status. Stool cultures were found to be positive for Shigella, and broad-spectrum antibiotic therapy was initiated. Because of the patient's reported sexual exposures, a rapid HIV point of care test was done and returned negative. In spite of intervention, the patient's vitals, labs, and symptoms failed to improve, and he developed septic shock requiring pressor support in the intensive care unit. Further workup for the etiology of the patient's sepsis included a CT abdomen and pelvis which showed findings concerning infectious colitis. Blood cultures later returned positive for Shigella, which was found to be resistant to multiple antibiotics. The patient was started on IV ceftriaxone with an improvement of and eventual resolution of symptoms. Shigellemia is a rare complication of infection with Shigella and necessitates further workup to avoid overlooking potential predisposing factors such as HIV or other immunocompromising conditions. Its susceptibilities should also be evaluated, as Shigella strains are more frequently becoming resistant to antibiotics that had previously been the therapies of choice.Treatment for recurrent intracranial neoplasms is often difficult and less standardized. Since its approval by the Food & Drug Administration (FDA), GammaTileTM (GT, GT Medical Technologies, Tempe, AZ), a novel collagen tile cesium brachytherapy, has been investigated for use in this population. This study presents the initial experience with the use of GT for patients with recurrent intracranial neoplasms at a tertiary referral center. A retrospective analysis of all patients with GT implantation from November 2019 to July 2021 was performed. Information regarding demographics, clinical history, imaging data, prior tumor treatment, dosing, surgical complications, and outcomes was collected. Twelve patients were included in this study. Pathologies included gliomas (five patients), meningiomas (five patients), and metastatic tumors (two patients). The median tumor volume treated was 24 cc (IQR 21.2 - 31.3 cc), and patients had a median of 7.5 tiles implanted (IQR 5.4 - 10.3). One patient had a delayed epidural hematoma requiring reoperation, which was unrelated to GT implantation. Median follow-up was seven months (IQR 3 -10), with the longest follow-up time of 20 months. Two patients have had local disease recurrence and three patients have had systemic progression of their disease. Three patients are deceased with survivals of 2.9, 4.8, and 5.8 months. Collagen tile brachytherapy is a safe and viable option for patients with recurrent intracranial tumors. Our data are consistent with early results seen at other institutions. Long-term data with larger patient populations are required to assess efficacy, safety, and indications for the use of this novel technology.Klippel-Trenaunay syndrome (KTS) is a rare disorder characterized by abnormal development of soft tissues, lymphatic system, and blood vessels. Major features include tissue and bone overgrowth, vein malformation, and port-wine stains with or without lymphatic abnormalities. It is crucial to review this rare syndrome to avoid any diagnostic delay. In addition, it is also vital to follow disease courses with symptomatic treatment for rare complex diseases, which would help clinicians understand and implement a better treatment plan in the future. We present the case of a 19-year-old male eventually diagnosed with KTS who initially presented with swelling of his feet and skin erosion with bloody discharge. Associated findings were bluish skin discoloration, nodularity, and bleeding per rectum, leading to anemia and subsequent heart failure. Colonoscopy/sigmoidoscopy showed vascular malformation and an active bleeding site. Our patient manifested most of the clinical attributes of KTS, with an interesting clinical course of arteriovenous, soft tissue, capillary, lymphatic, and vascular malformations. However, in our case, the patient is receiving only symptomatic treatment (blood transfusion) without any limb amputation or reconstruction surgery, leading to no further deterioration of the quality of life.
Various factors including the system of examination affect students' academic achievement. Annual or semester-based examinations are commonly observed practices. Students like semester system, as their academic performance is significantly higher in this system. Medical education in Pakistan has largely followed the British system of preclinical and clinical years of teaching followed by end-of-year examinations. In the wake of medical education reform, the semester system of examination having objective assessment was recently introduced in medical institutes of Pakistan. There is no empirical evidence regarding the effects of this change on medical students' academic achievement. This study aimed to assess whether the semester system has made any difference in the academic performance of medical students as compared to the annual system of examination.

Anatomy percentage scores of two batches of students who sequentially took annual and semester examinations were collected from a medical university.The data were analyzed for normality and later descriptive and inferential statistical tests were carried.
