Teaching approaches and satisfaction of medical students during anesthesia rotations: a multicenter cross-sectional study.

BACKGROUND: Anesthesia training is an important component of medical education. This multicenter study was conducted to determine the teaching approaches used during anesthesia training or rotations and to assess the satisfaction of the medical students. METHODS: This multicenter study was conducted in a cross-sectional design. The study was conducted among 5th and 6th year medical students who completed their anesthesia rotations in different training centers in Palestine. The data were collected using a questionnaire in adherence to the strengthening the reporting of observational studies in epidemiology statement. RESULTS: Questionnaires were returned by 385 medical students. The mean anesthesia rotation length was 12.4 ± 2.1 days. On average, the students witnessed 7.8 ± 4.9 procedures performed under general, regional, and local anesthesia in a week. Of the students, 135 (35.1%) and 126 (32.8%) stated that the educators always or often explained how and why they did procedures or techniques during the anesthesia rotation and assessed their baseline level of knowledge before giving new knowledge or explaining things. On the other hand, stepping back and allowing the trainees to work through, presenting articles or literature relevant to the case, and being open to trying new or different procedures or techniques were less often reported by the medical students. Less than half of the students were satisfied with their competencies gained through the anesthesia rotation. CONCLUSION: Educators used active and effective teaching or training approaches less frequently during the anesthesia rotations. The findings of this study also showed that the medical students were not satisfied with their competencies after their anesthesia rotations. More studies are still needed to determine the best ways to improve anesthesia rotations and medical education or training in Palestine.

Breastmilk cadmium levels and estimated infant exposure: a multicenter study of associated factors in a resource-limited country.

BACKGROUND: Despite the undisputed benefits of breastfeeding, infants might become exposed to xenobiotics that could be excreted into breast milk following maternal exposure. This study was conducted to assess breastmilk cadmium levels among lactating women in Palestine, a resource-limited country. Estimated daily intake (EDI) of cadmium via breastmilk was also calculated and predictors of high breastmilk cadmium levels and high infant exposure via breastmilk were identified. METHODS: This multicenter study was conducted using a descriptive-analytical design. The lactating women were recruited from different maternity and public health clinics in all regions of Palestine. Demographic variables and exposure to sources of cadmium were collected in an interviewer-administered questionnaire. Foremilk samples (about 5 mL) were collected in polyethylene tubes using the hand-expression technique. The breast milk samples were collected in the period between December 2020 and March 2021. A pre-validated method using inductively coupled plasma mass spectrometry (ICP-MS) was used to quantify breastmilk cadmium levels. EDI values were calculated from the quantified breastmilk cadmium levels. RESULTS: Breastmilk samples were obtained from 256 lactating women. The mean breastmilk cadmium level was 0.34 (SD: 0.33) µg / L and the mean EDI of cadmium via breastmilk was 0.059 (SD: 0.058) µg / kg per body weight / day. Breastmilk cadmium levels were quantified in 92.6% of the breastmilk samples. Of the breastmilk samples, 13 (5.1%) had cadmium levels above those reported as "normal" by the World Health Organization (WHO). Multiple linear regression showed that higher breastmilk cadmium levels and higher EDI were predicted by being a smoker, living in a refugee camp, living close to an industrial area, living close to disposal of wastes, living close to paint shops, living in a house with peeling / chipping paint, frequent use of cosmetics, frequent use of hair dyes, and not using vitamins. CONCLUSION: The breastmilk cadmium levels and infant exposure were predicted by maternal exposure to sources of cadmium. The findings reported in this study are valuable to antenatal and postnatal healthcare service providers. More studies are needed to plan and implement measures to reduce breastmilk cadmium levels and infants' exposure to cadmium via breastmilk.
