The test results on UAV-Head dataset show that our method can also achieve high precision pedestrian detection on UAV images with 88.5% AP and 75 FPS. In addition, we have conducted a precision calibration test to obtain the transformation matrix from images (vertical images and tilted images) to real-world coordinate. Based on the accurate pedestrian detection and the transformation matrix, the social distancing monitoring between individuals is reliably achieved.The specific factors and response strategies that affect COVID-19 transmission in local communities remain under-explored in the current literature due to a lack of data. Based on primary COVID-19 data collected at the community level in Wuhan, China, our study contributes a community-level investigation on COVID-19 transmission and response strategies by addressing two research questions 1) What community factors are associated with viral transmission? and 2) What are the key mechanisms behind policy interventions towards controlling viral transmission within local communities? We conducted two sets of analyses to address these two questions-quantitative analyses of the relationship between community factors and viral transmission and qualitative analyses of policy interventions on community transmission. Our findings show that the viral spread in local communities is irrelevant to the built environment of a community and its socioeconomic position but is related to its demographic composition. Specifically, groups under the age of 18 play an important role in viral transmission. Moreover, a series of community shutdown management initiatives (e.g., group buying, delivering supplies, and self-reporting of health conditions) play an important role in curbing viral transmission at the local level that can be applied to other geographic contexts.Skull base osteomyelitis is an inflammatory process that usually occurs secondary to necrotizing otitis externa or chronic mastoid infections. The involvement of the external auditory canal is typical of this condition and aids in its diagnosis. The treatment of skull base osteomyelitis is often complex and involves long-term intravenous antibiotics. Skull base osteomyelitis originating from the middle ear is a rare entity. We report a case of skull base osteomyelitis originating from the bilateral otitis media.Inferior vena cava thrombosis (IVCT) is a potentially fatal condition that may rarely occur in young patients with COVID-19 infection. This report describes a young adult female with a recent COVID 19 infection who presented with fever, bilateral flank pain, elevated inflammatory markers, and evidence of thrombosis in the inferior vena cava (IVC) on computed tomography (CT). The patient required treatment with anticoagulation therapy and catheter-directed thrombolysis, IVC filter placement, and mechanical suction-assist thrombectomy.Background This article investigates the inheritance, penetrance, clinical presentation, and therapeutic outcomes of hereditary head and neck paragangliomas (HNPGLs) by offering a four-generational report of an 18-member family affected by this rare condition. Methodology Information was compiled by examination of patients and a review of medical records and correspondence (retrospective case series). Results Six members of the 18-member family were diagnosed with HNPGL between 2002 and 2018. A known pathogenic point mutation in subunit D of the succinyl dehydrogenase complex (SDHD, c.317G>T, p.Gly106Val) was responsible for the tumor phenotype. The mutation could be revealed in seven family members, three diseased adults, one healthy adult, and three healthy children, out of the nine who consented to gene testing. The median age at diagnosis was 33.5 years (range 22-50 years). Five of the eight primary tumors were glomus caroticum, two were glomus jugulare, and one was a glomus vagale tumor. The therapeutic approaches were multimodal and included embolization therapy, surgery, radiation, and watchful waiting. Follow-up was reported for five of the six patients (mean follow-up of 34.8 months after primary therapy); three showed no disease progression or recurrence. Conclusions This study exemplifies the autosomal dominant, parent-of-origin-dependent inheritance and the high disease penetrance in hereditary paraganglioma-pheochromocytoma syndromes. Six out of a total of eight adult descendants (75%) of the original SDHD mutation carrier developed tumors, and the morbidity associated with the disease as well as its therapy was especially high in late-diagnosed, advanced cases. This substantiates the necessity for early radiologic surveillance and genetic testing.Introduction This study compares the immune response after coronavirus disease 2019 (COVID-19) inactivated virus vaccine between healthy individuals (HI) and patients on hemodialysis (HD). Methods In this cross-sectional, comparative study, the presence or absence of immunoglobulin G (IgG) anti-S antibody and IgG anti-S antibody titer was compared between HI, and patients on HD after two doses of COVID-19 vaccine. Results A total of 81 participants, 50 (61.7%) HD patients and 31 (38.3%) HI, were studied. The mean age was 52.9±12 in HD patients and 42±12.4 in HI. Vaccination responder rates were 80.6% in HI and 72% in HD patients after the first dose (p=0.38) and 93.5% in HI and 94% in HD at the third week of the second dose of the vaccine (p=0.93). The mean IgG antibody titer was 156.3±113.8 in HI and 143.4 ± 117.8 in HD patients (p=0.538) after the first dose and 186.7 ± 97.9 in HI and 180.6 ± 105.8 in HD patients (p=0.552) at three weeks of the second dose. No statistically significant difference was found in antibody titer with respect to gender, age, vaccine (BBIBP-CorV or Conovac), and hypertension. Diabetic HD patients had a lower antibody titer than non-diabetic HD patients (p=0.03) while participants who had a history of COVID-19 infection had a higher IgG titer (p = 0.001). The levels of IgG titer in the same patient increased, corresponding to the doses of vaccine (p less then 0.001). No HD patient developed COVID-19 infection till the third week of vaccination. Conclusion This study demonstrates a similar humoral response after COVID-19 inactivated virus vaccination in HD patients and HI. The response was lower among diabetic patients on HD and better in those with previous COVID-19 infection.
The study aimed to evaluate sexual function before and after inguinal hernia surgery using a standard, internationally approved, patient-administered questionnaire.

57 male inguinal hernia cases operated with the Lichtenstein hernioplasty technique were prospectively included in the study. Patients who agreed to participate in the study had the IIEF (International Index of Erectile Function) scoring system form consisting of 15 questions filled in preoperatively, during the first and sixth months after surgery. Patients' age, BMI, comorbidity, employment status, hernia type, hernia size, and single or bilateral hernia were recorded. Calcium folinate The relationship between these variables was evaluated by statistical analysis.

A statistically significant difference was found in terms of erectile function, sexual desire, intercourse function, and overall satisfaction, when the preop-postop first month, preop-postop sixth month, and postoperative first month-postop six-month scores were compared (p < 0.05).

Pain and swelling due to an inguinal hernia can negatively affect the sexual functions of the patient, and most of the patients benefit from this after the surgery. Sexual dysfunction may be one of the indications for an inguinal hernia operation.

Affected victims display a wide range of signs and symptoms that impact their health. This study aimed to investigate the prevalence of aggressive behavior toward healthcare workers and its effects on job satisfaction, general health, and mental health. Methodology An online survey comprising a revised version of the Negative Acts Questionnaire-Revised (NAQ-R) was distributed to the fellows, residents, and nurses working in a tertiary care hospital. The survey collected information regarding the group's demographics and their exposure to WPB encountered in the work environment while maintaining confidentiality. Survey results were analyzed using SPSS Statistics version 25 (IBM Corp., Armonk, NY, USA). Results Among the 339 participants who filled the survey, 53% of healthcare practitioners in different services had experienced some form of WPB. Among the targeted group, it was noted that female gender (50%), age between 31 and 41 years (57.03%), nurses (51.98%), non-Saudi practitioners (41.94%), and those working in inpatient settings (49.74%) were the most commonly affected individuals in the medical facility. Furthermore, higher bullying prevalence was correlated with lower job satisfaction and mental health levels. Conclusions Age, gender, job, and nationality were factors associated with increased susceptibility to WPB. WPB in any facility is an unfortunate event, especially in a healthcare setting. It affects health practitioners by decreasing job satisfaction, jeopardizing health, and increasing the risk of harm to patients. WPB will eventually have a negative impact on the medical facility and the healthcare sector. Hence, hospital administrations should be alarmed about the rise in WPB, and adequate measures must be taken to deal with the root cause of the problem.The phosphatase and tensin homolog (PTEN) hamartoma tumor syndrome (PHTS) is a collection of diseases stemming from mutations in the PTEN tumor suppressor gene and is characterized by variable expressivity and abnormal overgrowth in multiple body systems. Its clinical manifestations include, but are not limited to, lipomas, limb overgrowth, dermatologic lesions, and malignancy. The infrequency of occurrence and broadness of clinical presentation has made the diagnosis and differentiation of different subtypes of PHTS challenging. This case report describes a five-year-old patient with a history of autism and macrocephaly who presented to the emergency department with right lower quadrant (RLQ) pain concerning for appendicitis. A physical exam was significant for right leg hemihypertrophy. Imaging ruled out appendicitis but diagnosed two large right-sided abdominal lipomas. The patient was discharged with the recommendation to pursue genetic testing given the physical exam findings and history. Following confirmation of a PTEN tumor suppressor gene mutation, the patient continued to have increased frequency of abdominal pain, developed vision changes, and was diagnosed with a benign follicular thyroid nodule. Hemihypertrophy, recurrent unilateral lipomas, and a confirmed PTEN mutation are consistent with a diagnosis of Proteus-like syndrome, a rare subtype of PHTS.Background Competent medical coding is key to maintaining a successful dermatology practice. Resident billing performance can have significant financial implications for the academic institutions employing them. During their residency training, dermatology residents commonly find themselves responsible for the billing of patient encounters. However, despite the importance of adequate knowledge and skill in medical coding, recent data show inadequacies in this aspect of resident education. The goal of this study is to evaluate the impact of an interventional coding curriculum on dermatology residents' billing accuracy at our institution. Methodology Billing data, including evaluation and management (E/M) level of service, procedural codes, and current procedural terminology modifiers (if applicable) were queried from the electronic medical records (EMR) at a resident clinic seeing patients on three half-days each week. Billing codes were gathered from patient visits occurring in two separate time periods, before and after the intervention.
