Prevalence and correlates of generalized anxiety disorder and perceived stress among Sudanese medical students.

BACKGROUND: Generalized Anxiety Disorder (GAD) causes significant disturbance in an individual's well-being and activity. Whereby, interfering with the dynamic progress in life. Also, anxiety is a product of stress and a major predictor of academic performance. This study aimed to assess the prevalence of Generalized Anxiety Disorder (GAD), measure levels of anxiety and perceived stress, evaluate the academic profile, identify lifestyle characteristics, and explore the relationship between these factors. METHODS: In this cross-sectional study, 340 Sudanese medical students filled out online questionnaires, composed of the sociodemographic and lifestyle characteristics, academic profile, Generalized Anxiety Disorder-2 scale (GAD-2), and Perceived Stress Scale-10 (PSS-10). Descriptive and inferential statistics were applied using Statistical Package for Social Science (SPSS) Version 20.0 for data analysis. RESULTS: Of 340 medical students, 3.8% of them were diagnosed with GAD, while 29.1% scored ≥ 3 in GAD-2, indicating a possible diagnosis. The study found that 9.7% of the participants used addictive substances, with 42% of them having high GAD-2 scores. Moreover, high anxiety levels were associated with high-stress scores (p-value = 0.000). Also, high GAD-2 scores were significantly associated with students who spent less than 10,000 SDG (18 USD) weekly, spent more time on entertainment using smart devices (p-value = 0.004), and had an unhealthy diet (p-value = 0.004). Low anxiety levels were associated with better sleep quality (p-value = 0.00), satisfaction with religious practices (p-value = 0.00), and increased leisure/hobby time (p-value = 0.018). High-stress levels were observed in females (p-value = 0.035), those with lower academic performance satisfaction levels, and increased hours of smart device usage for entertainment (p-value = 0.001). Reduced stress levels were associated with being ≥ 23 years old, increased leisure/hobby time (p-value = 0.002), satisfaction with religious practices [F(3, 166.6) = 10.8, p-value = 0.00)], and having a healthy diet (p-value = 0.006). CONCLUSION: The low prevalence of GAD corresponded with previous literature, but 29.1% of medical students had a high probability of having GAD. The study emphasizes on providing accessible mental health services for medical students and interventions addressing modifiable risk factors.

The role of imaging in malignant pleural mesothelioma: an update after the 2018 BTS guidelines.

Malignant pleural mesothelioma (MPM) is a primary malignancy of the pleura and is associated with a poor outcome. The symptoms and signs of malignant mesothelioma present late in the natural history of the disease and are non-specific, making the diagnosis challenging and imaging key. In 2018, the British Thoracic Society (BTS) updated the guideline on diagnosis, staging, and follow-up of patients with MPM. These recommendations are discussed in this review of the current literature on imaging of MPM. It is estimated MPM will continue to cause serious morbidity and mortality in the UK late into the 21st century, and internationally, people continue to be exposed to asbestos. We aim to update the reader on current and future imaging strategies, which could aid early diagnosis of pleural malignancy and provide an update on staging and assessment of tumour response.

Are Indians and females less tolerant to pain? An observational study using a laboratory pain model.

In Malaysia, it is a common belief among health care workers that females and Indians have lower pain threshold. This experience, although based on anecdotal experience in the healthcare setting, does not allow differentiation between pain tolerance, and pain expression. To determine whether there is a difference in the tolerance to pain between the three main ethnic groups, namely the Malays, Chinese and Indians as well as between males and females. This was a prospective study, using a laboratory pain model (ischaemic pain tolerance) to determine the pain tolerance of 152 IMU medical students. The mean age of the students was 21.8 years (range 18-29 years). All of them were unmarried. The median of ischaemic pain tolerance for Malays, Chinese and Indians were 639s, 695s and 613s respectively (p = 0.779). However, statistically significant difference in ischaemic pain tolerance for males and females Indian students were observed. Possible ethnic difference in pain tolerance in casual observation is not verified by this laboratory pain model. Difference in pain tolerance between genders is shown only for Indians.

Pain morbidity in primary care - preliminary observations from two different primary care settings.

The prevalence of pain complaints as a reason for patient-doctor encounters in the local primary care setting is unknown. We performed a cross-sectional survey of such encounters in one public primary care clinic (KK) and 17 general practice clinics (GP), from the city of Seremban, Negeri Sembilan, Malaysia. Reasons for visits were recorded by doctors in KK and medical students in GP using a structured questionnaire. Morbidity data was coded using the International Classification of Primary Care (ICPC-2). A total of 2234 encounters were recorded (80.9% from KK, 19.1% from GP). The overall prevalence of pain complaints was 31.9% with a significant difference between the two cohorts (KK 28.7% and GP 45.2%, p<0.001). Musculoskeletal pain complaints were more common in KK than GP (40.9% versus 29.7%, p<0.05). Of the 3 main ethnic groups in Malaysia (Malay, Chinese and Indian) the Indian patients at KK had the highest prevalence of pain complaints and the Chinese at the GP had the lowest. Thus pain was a common complaint in the two different primary care settings studied. Some of the differences observed are probably due to the differences in the healthcare seeking behaviour of patients consulting at these two settings as well as differences in the payment systems.

[Attendance at a health center by clandestine prostitutes in Djibouti]. / Fréquentation d'un centre de santé par les prostituées clandestines à Djibouti.

The extent of clandestine prostitution in Djibouti is difficult to evaluate. Due to the secrecy of the prostitutes and often their low level of education, the follow-up of these patients is also difficult. A sexually transmitted disease clinic specialized in the treatment of prostitutes and their customers has been established in Djibouti since 1963. We tried to evaluate the available data on the clandestine prostitutes attendance at the center. The population was young with a mean age of 23 years. Fifty percent had children and 60% were divorced or separated. Ninety-one percent were Ethiopian and 73% lived in the same district of the city of Djibouti. Almost half of them were HIV positive. The duration of residence in Djibouti before the first visit to the clinic varied widely with a median of 12 months. However, the total duration of prostitution before the first visit was shorter with a median of 3 months. The complaint at the first visit was most often minor. Among the prostitutes who first came to the center in 1993, half of them came only once. The overall duration of follow-up was 8 months, for an average of 3.7 visits per patient. Alternatively, 20 patients had more than 10 consultations and this represented one third of the consultations given to previous patients. This last group is the only one which tended to respect the monthly visits proposed to each patient at the first consultation. The other patients seemed to come only when they felt ill. The routine statistical activities which separately counted the new and previous patients gave an optimistic but faulty impression: these showed an increase in the total number of patients and also an increase in the percentage of previous patients visiting (from 42 to 69% between 1988 and 1994). It is difficult to evaluate the follow-up of such a mobile population. The few patients known for their fidelity contrasted with the fact that half of the patients had visited the center only once. This low frequency of visitation could be due to either the management of the center or to the lack of proximity of the contacts within the districts.
