RESUMO
In a cross-sectional survey in Omdurman, Sudan, during March-April 2021, we estimated that 54.6% of the population had detectable severe acute respiratory syndrome coronavirus 2 antibodies. Overall population death rates among those >50 years of age increased 74% over the first coronavirus disease pandemic year.

Advanced surgical technologies consist of remote and virtual platforms that facilitate surgical care and education. It also includes the infrastructure necessary to utilize these platforms (e.g., internet access, robotic systems, and simulators). Given that 5 billion people lack access to safe and timely surgical care, the appeal of these technologies to the field of global surgery lies primarily in its ability to eliminate geographical barriers and address surgeon shortages. This article discusses the use of virtual and remote technologies in resource-limited settings, the potential applications of these technologies, the possible barriers to their integration, and the impact these technologies may have on access to surgical care and education. Specifically, it will explore how robotic surgery, telesurgery, virtual education platforms, and simulations have the potential to be instrumental in enhancing worldwide access to safe surgical care.
RESUMO
Khalawi are non-governmental, traditional educational boarding institutions, widely scattered in Sudan. Many Khalawi are resource-limited with deficient feeding and poor housing conditions, which could seriously affect the students' health. A cross-sectional study was conducted, involving all students of a Khalwa in Sharg Al-Neel Locality, Khartoum State. Demographic data were collected using a structured questionnaire with anthropometric measurements, along with laboratory and clinical assessments for anaemia. The dietary behaviours of students were also assessed using Global School-based Health Survey. Statistical analysis was conducted using SPSS software. A total of 131 students were included in this study. Their mean age was 13.7 ± 2.7 years, nearly half of them were from Darfur State in western Sudan, and the majority of them are primary school students. Upon assessment, many displayed serious symptoms and signs of anaemia namely: conjunctival pallor, palmar pallor, fatigability, lightheadedness and palpitation. Based on their haemoglobin testing, 95% were anemic and 24% had severe anaemia. Although 63.6% of them had normal body mass index (4.5%), 11.4%, were found 'severely thin' and 'thin', respectively. Regarding their dietary habits, 46.8% of them consumed milk or milk products less than one time per day, while 20.6% did not consume milk products in the past 30 days. Moreover, 39.4%, 44.9% and 39.4% did not consume any vegetables, fruits or fruit juice, respectively, in the past month. Students of Khalwa displayed poor dietary habits, which resulted in nutritional deficiencies. Programmes must be directed towards improving the quality of diet provided at these schools.
RESUMO
Khalawi are one of the most ancient non-governmental educational institutions that are commonly found all over Sudan playing a major role in the Sudanese society. The majority of Khalwa students are children. This study was part of a mixed methods project, conducted by Khartoum Medical Students' Association, aiming to investigate the health status of Khalwa students. It is a cross-sectional study carried out in Mustafa Alfadni Khalwa, Sharg Al-Neel suburb in Khartoum State. The participants were clinically assessed by a doctor and data were collected by using a data entry tool made specially to screen for major infectious diseases among students. The results showed a mean age of 13.7 years. Most of the students (47.7%) were originally from Darfur, and 27.5% of them had only Khalwa education. Respiratory clinic results revealed that 10% were complaining of cough, and 3.4% were diagnosed with pneumonia. Additionally, 44.6% of the students had tinea capitis and 21% had scabies. On examination, 2.3% and 1.1% had mild splenomegaly and hepatomegaly, respectively. Infectious conjunctivitis and trachoma were reported among 11.7% and 10.9%, respectively. Blood films for malaria were positive in 51.3%. Macroscopic and microscopic haematuria was evident among 13.4% and 10.8% of the participants, respectively. Stool examination results showed that 1.4% of the students had worms, 1.5% had ova and 18.8% had red blood cells in stools. Infectious diseases are very common among Khalwa students and their living environment is facilitating the transmission of these diseases. Agent control and sanitation improvement are crucial to decrease such infectious diseases.
RESUMO
BACKGROUND: Anterior cruciate ligament reconstruction (ACLR) with hamstring autograft has gained popularity. However, an unpredictably small graft diameter has been a drawback of this technique. Smaller graft diameter has been associated with increased risk of revision, and increasing the number of strands has been reported as a successful technique to increase the graft diameter. PURPOSE: To compare failure rates of 5-strand (5HS) and 6-strand (6HS) hamstring autograft compared with conventional 4-strand (4HS) hamstring autograft. We describe the technique in detail, supplemented by photographs and illustrations, to provide a reproducible technique to avoid the variable and often insufficient 4HS graft diameter reported in the literature. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: We retrospectively reviewed prospectively collected data of all primary hamstring autograft ACLRs performed at our institution with a minimum 2-year follow-up and 8.0-mm graft diameter. A total of 413 consecutive knees met the study inclusion and exclusion criteria. The study population was divided into 5HS and 6HS groups as well as a 4HS control group. The primary outcome was failure of ACLR, defined as persistent or recurrent instability and/or revision ACLR. RESULTS: The analysis included 224, 156, and 33 knees in the 5HS, 6HS, and 4HS groups, respectively. The overall ACLR failure rate in this study was 11 cases (8%): 5 cases for 5HS, 3 cases for 6HS, and 3 cases for 4HS. No statistically significant differences were found among groups (P = .06). The mean graft diameter was 9 mm, and the mean follow-up was 44.27 months. CONCLUSION: The 5HS and 6HS constructs have similar failure rates to the conventional 4HS construct of 8.0-mm diameter and are therefore safe and reliable to increase the diameter of relatively smaller hamstring autografts. We strongly recommend using this technique when the length of the tendons permits to avoid failures reportedly associated with inadequate graft size.
