Role of respiratory characteristics in treatment adherence with noninvasive home mechanical ventilation in myotonic dystrophy type 1, a retrospective study.

Chronic respiratory insufficiency is common in patients with myotonic dystrophy type 1 (DM1) and can be treated with noninvasive home mechanical ventilation (HMV). HMV is not always tolerated well resulting in low treatment adherence. We aimed to analyze if baseline respiratory characteristics such as pulmonary function, level of pCO2 and presence of sleep apnea are associated with HMV treatment adherence in DM1 patients. Pulmonary function testing, polysomnography and blood gas measurement data of DM1 patients were retrospectively collected. Initiation of HMV and treatment adherence after one year was documented. Patients with low treatment adherence (average daily use of HMV <5 h) were grouped with patients that discontinued HMV and compared with patients with high treatment adherence (average daily use of HMV >5 h). HMV was initiated in 101 patients. After one year, 58 patients had low treatment adherence. There were no differences between the low and high treatment adherence group regarding the respiratory characteristics. None of the included predictors (gender, age, body mass index, cytosine-thymine-guanine repeat length, FVC, daytime pCO2, bicarbonate, nighttime pCO2, nighttime base excess, apnea-hypopnea index and mean saturation during sleep) was able to significantly predict high treatment adherence. In conclusion, the respiratory characteristics are not associated with treatment adherence with HMV in DM1 patients and cannot be used to identify patients at risk for low HMV treatment adherence.

The Level of Anatomical Knowledge, Hard to Establish: a Systematic Narrative Review.

Objective: This literature review aimed to gain more insight into the level of anatomical knowledge based on published measurements among medical students, residents, fellows, and specialists. Methods: We performed an extensive literature search in three online databases: Medline (using PubMed), Web of Science, and Education Resources Information Centre (ERIC). Results: A total of 30 relevant studies were found. In these studies, participants took different anatomy tests, and their mean/median scaled scores range from 22.5 to 82.4% on a 0 to 100% scale. Conclusion: This review provides an overview of what is known about measured anatomical knowledge. After critically reviewing the literature, we have to conclude that the existing literature confirms that anatomical knowledge is hard to establish, mainly due to the lack of standardisation.Further research should focus on ways to define and assess 'desired anatomical knowledge' in different contexts. In a next phase, we can discuss if anatomical knowledge is lacking and if interventions are needed.

Disparities between Rural and Urban Areas of the Central Region of Saudi Arabia in the Utilization and Time-Centeredness of Emergency Medical Services.

The purpose of this study was to explore differences in characteristics of missions dispatched by Emergency Medical Services (EMS) between rural and urban areas of Riyadh province in Saudi Arabia (SA). It also aimed at identifying weaknesses related to utilization and Response Time (RT). The study retrospectively evaluated 146,639 completed missions in 2018 by measuring the utilization rate in rural and urban areas. The study shows there are six times more ambulance crews available for rural areas compared to urban. There were 22.1 missions per 1000 urban inhabitants and 11.2 missions per 1000 in rural areas. The median RT for high urgent trauma cases was 20.2 min in rural compared to 15.2 min in urban areas (p < 0.001). In urban areas, the median RT for high urgent medical cases was 16.1 min, while it was 15.2 min for high urgent trauma cases. Around 62.3% of emergency cases in urban and 56.5% in rural areas were responded to within 20.00 min. Women utilized EMS less frequently. The RT was increased in urban areas compared to previous studies. The RT in the central region of SA has been identified as equal, or less than 20.00 min in 62.4% of all emergency cases. To further improve adherence to the 20' target, reorganizing the lowest urgent cases in the rural areas seems necessary.

Obstetric anal sphincter injury: a follow-up questionnaire study on longer-term outcomes.

INTRODUCTION AND HYPOTHESIS: Obstetric anal sphincter injuries (OASIS) contribute significantly to the development of anal incontinence (AI) in women. The aim of this study was to establish the incidence of AI after OASIS and to study the influence on the quality of life (QoL) in patients with OASIS. METHODS: This cohort study, with prospective case-control follow-up, involves women who were treated for OASIS between 2005 and 2012 in two academic medical centers in The Netherlands. Three hundred and thirteen patients and 780 controls were invited to complete a validated questionnaire (Defecation Distress Inventory, Wexner Incontinence Score, and Fecal Instrument Quality of Life) regarding symptoms and bother of AI subsequent and QoL after delivery. The main outcome measures were the presence of AI and the impact on QoL. RESULTS: The questionnaire was completed by 141 patients and 194 controls. Mean follow-up was 4 years (range 1-9 years) in both groups. In the patient group, 55 women (39 %) reported AI symptoms compared with 38 women (20 %) in the control group (odds ratio 2.7, 95 % confidence interval 1.66-4.47, p < 0.01). In women who experienced symptoms of AI as very bothersome, QoL was affected in 14 (82.0 %) patients and three (33.5 %) controls (p = 0.012). CONCLUSIONS: In this study, women with OASIS had a more than doubled risk of longer-term bothersome symptoms of AI compared with controls. Symptoms were experienced as bothersome and as having an influence on QoL.
