This study was useful in evaluating the hazardous effects of uncontrolled use of Pb in general and in assessing the developmental and neurotoxicity of foetuses due to exposure during pregnancy in particular. Co-administration of garlic has beneficial effects in amelioration of Pb-induced neurotoxicity and reversing the histopathological changes of the cerebellum of mother rats and foetuses.

The COVID-19 pandemic changed the world of medical education, moving it years ahead of time into the future. Many concepts needed to be changed, so did the methodologies. Nevertheless, clinical assessment remained tricky. This work highlights the outcome of the work of College of Medicine and Medical Sciences at the Arabian Gulf University in Bahrain in performing virtual clinical examination using Zoom™. Tips in this article are meant to help plan, implement and evaluate clinical assessments virtually.

Background The COVID-19 pandemic has impacted all spheres of society including medical education and healthcare systems. In response to the pandemic, there has been a transition in medical education practice from traditional forms of teaching to online instruction delivery and virtual learning. Effective clinical microbiology education involves a combination of 'hands-on' practical learning and instructional delivery of scientific knowledge. Microbiology practical laboratories are critical learning environments offering 'hands-on' learning experiences that cannot be replicated through online learning. We conducted a mixed-methods study to understand the perception of online and face-to-face microbiology laboratory sessions among the medical students and microbiology faculty at Arabian Gulf University (AGU). Methods The study participants were third and fourth-year undergraduate medical students and faculty involved in delivering microbiology labs at AGU. The questionnaire consisted of questions ranging from perceived learning style to attitude towards online delivery of microbiology curriculum. After the questionnaire administration (google form), focus group discussion (FGD) was conducted for students and microbiology faculty separately. Results Among 168 students, 50.6% preferred face-to-face lab sessions as compared to 30.4% who preferred online labs, and 51.8% considered online labs to be an essential addition to face-to-face labs. Among the faculty, 85.7% preferred the face-to-face mode of teaching. All the faculty (100%) disagreed that all the microbiology labs teaching should be online. 57.2% considered online labs to be an essential addition to traditional face-to-face labs. Both faculty and students hold that a blended mode of instructional delivery is vital and indispensable for the transfer of skills and knowledge for microbiology students. Conclusion The blended mode of delivering microbiology laboratory sessions in medical school is successful and well-received by both students and faculty. Students take the responsibility for furthering their own learning and understanding of concepts. Instructors have also noticed that blending learning strategies also successfully enhances the development of cognitive skills and problem-solving abilities in students. A review of the microbiology lab curriculum is necessary to identify content areas that can be delivered effectively through online, face-to-face lab sessions, or both, supported with appropriate tools and infrastructure.

The challenges imposed by the ongoing outbreak of severe acute respiratory syndrome coronavirus-2 affects every aspect of our modern world, ranging from our health to our socio-economic needs. Our existence highly depends on the vaccine’s availability, which demands in-depth research of the available strains and their mutations. In this work, we have analyzed all the available SERS-CoV2 genomes isolated from the Kingdom of Bahrain in terms of their variance and origin analysis. We have predicted various known and unique mutations in the SERS-CoV2 isolated from Bahrain. The complexity of the phylogenetic tree and dot plot representation of the strains mentioned above with other isolates of Asia indicates the versatility and multiple origins of Bahrain’s SERS-CoV2 isolates. We have also identified two high impact spike mutations from these strains which increase the virulence of SARS-CoV2. Our research could have a high impact on vaccine development and distinguishes the source of SERS-CoV2 in the Kingdom of Bahrain.

Purpose: Currency seems to represent an important vehicle for transmission of pathogenic microorganisms, thus a potential in affecting the public health. Digital transactions are more common in developed countries; however, handling cash currency is still very common in many countries including Bahrain. A recent study from Australia reported that SARS-CoV-2 may survive for 28 days on smooth surfaces (including banknotes), however the study was purely experimental and done in controlled laboratory environment. There were worldwide speculations suggesting the possible transmission of SARS-CoV-2 infection through currency notes. A recent study from Bangladesh reported presence of SARS-CoV-2 in approximately 7% of currency samples collected from the community. No such study has been performed on Bahraini currency, so the present study was proposed to screen the cash currency in circulation in Bahrain for the possible presence of SARS-CoV-2. Method: We collected notes and coins of Bahraini currency and a few of Saudi riyals from different public sources of currency exchange. Two time points were selected for collection when percentage of tested positive cases was on its peak. All the samples were tested for the presence of SARS-CoV-2 antigen with rapid antigen detection kit and qRT-PCR method. For initial validation, 5 samples each of potential SARS-CoV-2 RNAs extracted from known positive cases and 5 samples of extracted RNA from known negative persons were tested by rapid antigen detection kit and qRT-PCR. The results of qRT-PCR were interpreted as per the interpretation chart provided by the supplier. Results: During the study period, a total of 250 currency samples were collected including different denominations of currency notes and coins. Majority of the currency samples were collected from grocery stores followed by food outlets. Following validation, the currency samples were tested, and all turned negative for SARS-CoV-2 by rapid antigen detection test as well as by RT-PCR. Conclusion: This study predicts on Bahraini currency posing no threat of SARS-CoV-2 transmission via currency exchange.
