SARS-CoV-2 journey: from alpha variant to omicron and its sub-variants.

The COVID-19 pandemic has affected hundreds of millions of individuals and caused more than six million deaths. The prolonged pandemic duration and the continual inter-individual transmissibility have contributed to the emergence of a wide variety of SARS-CoV-2 variants. Genomic surveillance and phylogenetic studies have shown that substantial mutations in crucial supersites of spike glycoprotein modulate the binding affinity of the evolved SARS-COV-2 lineages to ACE2 receptors and modify the binding of spike protein with neutralizing antibodies. The immunological spike mutations have been associated with differential transmissibility, infectivity, and therapeutic efficacy of the vaccines and the immunological therapies among the new variants. This review highlights the diverse genetic mutations assimilated in various SARS-CoV-2 variants. The implications of the acquired mutations related to viral transmission, infectivity, and COVID-19 severity are discussed. This review also addresses the effectiveness of human neutralizing antibodies induced by SARS-CoV-2 infection or immunization and the therapeutic antibodies against the ascended variants.

Navigating miscarriage in Jordan: understanding emotional responses and coping strategies.

BACKGROUND: Miscarriages account for 20% of clinically confirmed pregnancies and up to 50% of all pregnancies and is considered one of the most heartbreaking events experienced by women. The current study aimed to explore participants' perceptions and practices and how they link with the negative emotions of miscarriage. METHODS: In this cross-sectional study a web-based questionnaire was used to gather data from 355 women living in Jordan who had experienced a previous miscarriage. The questionnaire consisted of four sections, including socio-demographic information, experience with miscarriage, emotions after the experience, and self-care practices. Participants were recruited through social media platforms from April to August 2022. Data were analyzed using SPSS, and descriptive statistics, chi-square test, and binomial regression were performed to examine the results. RESULTS: The results show that the majority of participants were in the age group of 22-34 years and a larger percentage of participants hold a Bachelor's degree and were employed. All participants had experienced a previous miscarriage with 53.8% having one, 27.0% having two, and 19.2% having three or more miscarriages. In addition, most miscarriages did not have an explanation for their cause (77.5%), but vaginal bleeding was the most reported symptom (55.2%) and surgical management was predominant (48.7%). Most participants reported adequate emotional support from partners and family (63.7% and 62.3%, respectively). Almost half (48.7%) of the respondents felt like they had lost a child and those who did not receive any social support had a higher association with the same feeling (p = 0.005). Of the participating women, 40.3% decided to postpone another pregnancy while 20.0% planned for a subsequent pregnancy. The feeling of shame regarding the miscarriage was the main driver for women to get pregnant again (Odd ration [OR] 2.98; 95% confidence interval (CI) 1.31-6.82; p = 0.01). CONCLUSIONS: The findings highlight the emotional impact of miscarriage on women and the need for proper support and self-care practices.

COVID-19 infection and vaccine have no impact on in-vitro fertilization (IVF) outcome.

To investigate the effect of COVID-19 infection or vaccine on IVF outcome. This is a multicenter retrospective study. Data were collected from all patients treated in the ART units between September and November 2021 after the vaccination of the general population began. Medical records of all patients who had IVF/intracytoplasmic sperm injection (ICSI) were retrospectively reviewed. Patients were categorized into four groups: previously infected by COVID-19, vaccinated by COVID vaccine, previously infected and vaccinated, or neither infected nor vaccinated. Total number of participants 151 (vaccinated only 66, infected only 18, vaccinated and previously infected 34, and control 33. Outcomes (ET on day of trigger, number of oocytes retrieved, quality of oocytes, number of fertilized oocytes, number and quality of embryos, number of embryos transferred, number of embryos frozen, implantation rate and clinical pregnancy rate) were compared between these four groups. Moreover, we compared the outcome before and post infection, as well as before and post vaccine in a group of patients. No evidence was found to suggest that COVID-19 disease or SARS-CoV-2 Vaccine adversely affects Clinical pregnancy rates (positive fetal heartbeat) (OR 0.9, CI 0.5-1.9, OR 1.8, CI 0.9-3.6, respectively) and the following parameters: fertilization rate, implantation rate, positive bHcg) (OR 0.9, CI 0.5-1.8, OR 1.5, CI 0.7-2.9, respectively). Although a limitation of our study is the small comparison groups, and the wide confidence intervals in the Odds Ratio estimates.

COVID-19 and Semen Fluid Parameters, a Retrospective Study from Infertility Clinics.

The study of the effects of SARS-CoV-2 infection and/or vaccination on semen fluid analysis (SFA) parameters is still incomplete. The aim of this study is to assess the effect of COVID-19 infection and vaccination on sperm parameters for a sample of individuals visiting multi-infertility clinics in Jordan. SFA records were collected retrospectively between September and November 2021 and analyzed using Jamovi software (version 2.2.5 for Windows); p-values < 0.05 were considered statistically significant. Sperm concentration, progressive motility, normal morphology, and semen liquefaction time, volume, and viscosity were compared among two data categories. In the first category of data, SFA records from 354 participants were separated into four groups: only vaccinated, infected and vaccinated, neither infected nor vaccinated, and only infected. In the other category, SFA from 49 subjects before their infection and/or vaccination and after were classified into the same mentioned groups and analyzed. There were no statistically significant differences between the studied parameters in the SFA records in the first data category and the second. Nevertheless, the sperm concentration was higher among vaccinated subjects compared to unvaccinated ones (p = 0.04). It is concluded that SARS-CoV-2 infection and vaccines have no negative effects on SFA parameters.

Conception Preferences during COVID-19 Pandemic Lockdowns.

Background: The COVID-19 lockdowns imposed new challenges to couples who were planning to conceive. In this research paper, we aimed to study the perceptions of women in Jordan during the pandemic regarding fertility behavior, the desire to use assisted reproductive technology (ART) and the awareness and beliefs of potential risks related to conception. Methods: A validated online-based questionnaire was distributed to women from April-May 2020, Statistical analysis was performed using the statistical software SPSS version 22 and R software (2020); p values ≤ 0.05 were considered statistically significant. Results: The total number of participants was 814 women, with 78.2% of the participants (58.7% fertile and 76.6% infertile) believing that pregnancy during the COVID-19 pandemic could be risky. Among them, 16% and 40%, respectively, were trying to conceive during the pandemic, and 97.4% and 89.9%, respectively, were not willing to use ART if needed during the pandemic. Young, nulliparous women who were married for less than one year were significantly associated with the desire to conceive during the COVID-19 pandemic. Conclusion: This study concluded that the fertility behavior of women in Jordan changed during the pandemic, and their desire for natural conception and for using ART declined, as they believed that there were potential risks related to conceiving during the pandemic. However, the effect was greater among the general fertile population than the infertile.

Remote learning during Covid-19 lockdown: A study on anatomy and histology education for pharmacy students in Jordan.

The Covid-19 pandemic has changed almost all aspects of education. The anatomy and histology courses for pharmacy students focus heavily on the face-to-face communication of theory and practical knowledge, and due to the pandemic, only theory content was delivered in an online format. This brought up many concerns about pharmacy student preparedness. This work explores the effectiveness and student perspective of remote teaching of the theoretical anatomy and histology course in Jordanian universities from the perspective of pharmacy students. The objectives are to determine the strengths, challenges, and the effectiveness of remote delivery on student learning. An online-based validated questionnaire was distributed to students majoring in Pharmacy and enrolled in the course during the second semester of 2019-2020 at 11 universities in Jordan. A total of 442 students participated in the study. Results showed that there were significant differences in perceptions of the social media platforms used in distance learning and remote delivery of the course. Most participants had positive perceptions of the educational process and studying via distance learning. There were many strengths noted including time flexibility and several challenges such as the lack of face-to-face interaction with instructors, inadequate internet connectivity, and technical issues. In conclusion, online-taught anatomy and histology course during the Covid-19 lockdown in Jordan was a success as perceived by students, but the course still possessed challenges need to be overcome in the future.

Use of complementary and alternative therapies in infants under 3 months in Jordan.

BACKGROUND: The use of complementary and alternative medicine in infants to maintain health and treat illnesses is popular in Jordan. No guidelines or regulations govern their use. AIMS: This study explored mothers' knowledge and use of complementary and alternative therapies for infants younger than 3 months in Jordan and their reasons for using these remedies. METHODS: This was a cross-sectional study of a convenience sample of mothers of babies born in 2015 in Jordan. Data were collected using a questionnaire posted on six Facebook groups that target mothers in Jordan. Mothers were asked about their use of several complementary and alternative therapies for different conditions. RESULTS: Of 1028 questionnaires received, 520 were included in the analysis. Most mothers (81.3%) were 18-29 years old and had a university degree (78.3%). Most knew about the use of the complementary and alternative medicines for bloating/ colic but had never used them. Of the medicines used for bloating/colic, aniseed was most often used (by 70.2% of mothers). Aniseed was also used by 60.8% of mothers to help their baby sleep and by 48.1% for constipation. The main reasons for using these remedies were availability at home (60.4%) and social acceptability of their use (55.4%). The main sources of information about these medicines were older female relatives (78.1%) and social media (56.0%). CONCLUSIONS: The use of complementary and alternative medicines for babies is common in Jordan. Efforts are needed to increase awareness among mothers of the risks, side-effects and efficacy of complementary and alternative therapies in infants.

Sternalis muscle in jordanian population: a prevalence study and level of physicians' awareness.

Sternalis muscle (SM) is an anatomical variant that lies parallel to the sternum. It is present in (8%) of human population. Awareness about its presence during thoracic imaging is important, since it might be misdiagnosed as a tumor. This study is the first that discusses the prevalence of SM in the Jordanian population and document the level of awareness about SM among intern doctors and surgery and radiology residents. Our aims are to know the prevalence of SM in the Jordanian population, using thoracic multi-detector computerized tomography (CT) images, and to assess the awareness about SM among a sample of intern and resident Jordanian physicians. Random anonymous axial thoracic multi-detector CT images of 1,709 (801 females and 908 males) Jordanian patients, were examined for the presence or absence of unilateral and/or bilateral SM. A questionnaire aiming to identify SM was distributed among 175 intern doctors, 26 surgery resident and 28 radiology resident doctors, their answers were summarized. The prevalence of SM among Jordanians is 5.9%. The prevalence of unilateral SM is 2.1% on the right side of the thorax and 1.9% on the left side, bilateral prevalence was 1.8%. While 35.7% of the radiology residents could identify SM using CT and/or anatomy images, only 3.9% of surgery residents and none of the intern doctors could. We concluded that SM is present in the Jordanian population, with a prevalence of 5.9% which falls within the global average. Intern doctors and surgery and radiology residents are almost unaware and unfamiliar about SM.

Azygos Lobe: Prevalence of an Anatomical Variant and Its Recognition among Postgraduate Physicians.

The right azygos lobe is a rare anatomical variant of the upper lung lobe that can be misdiagnosed as a neoplasm, a lung abscess, or a bulla. The aim of this study was to assess the prevalence of right azygos lobe and to evaluate the ability of postgraduate doctors to correctly identify right azygos lobe. We analyzed a total of 1709 axial thoracic multi-detector computed tomography (CT) images for the presence of an azygos lobe. Additionally, a paper-based survey was distributed among a sample of intern doctors and radiology and surgery residents, asking them to identify the right azygos lobe in a CT image and in an anatomy figure. Results showed that the prevalence of the right azygos lobe in the study sample was 0.88%. Men have more right azygos lobes than women. None of the intern doctors or surgery residents identified the right azygos lobe correctly, whereas more than half (57.1%) of the radiology residents did. Most of the incorrect answers about the CT scan were related to the bronchi (25.0%). The apex of the lung (17.7%) and the superior vena cava (17.7%) were the most common incorrect answers about the anatomy figure. In conclusion, the prevalence of the right azygos lobe in the current study is within the range of previously published literature. More education should be given for the identification of the right azygos lobe during anatomy and clinical teaching.

The awareness of the Jordanian population about OTC medications: A cross-sectional study.

Due to the shortage of literature related to the safe use of over-the-counter (OTC) products by patients worldwide, the aim of this study was to evaluate people's knowledge and attitudes regarding the use of OTC products in Jordan. Using an internet-based questionnaire mainly spread through social media platforms, a descriptive cross-sectional study was conducted with Jordanian candidates who consume OTC products. A total of 274 OTC product users answered the survey questions. The results showed that analgesics were the most commonly used OTC products among the participants (50.4%). The majority used the OTC products only as needed rather than on a regular basis. Only 42.4% of the participants sought a pharmacist's help in determining the dose of the OTC medicine. Most of the participants were very interested in reading a patient information leaflet (80.3%) and the side effects and contraindications (89.5%). The majority of participants agreed that antibiotics have to be prescribed (68.5%), and anti-allergy medications should not be used as sleep aid medications (75.0%). About 53.4% thought that OTCs are sometimes enough to treat their health conditions without the need to follow-up with a physician. A chi-square analysis showed an association between gender, age, educational level and having a family member in the medical field and OTC products knowledge among Jordanians. Females, for example, were more interested in reading leaflet, checking production and expiry dates, knowing adverse effects, and appropriate storage conditions (P < .001, 0.022, 0.003, 0.007, respectively). We concluded that a good level of knowledge on the use of OTC products among the study population was identified in the present study.

Rosmarinic acid reverses the effects of metronidazole-induced infertility in male albino rats.

Rosmarinic acid (RA) is a natural antioxidant that has many biological activities. In the present study we investigated the potential of RA to reverse the negative effects of the widely used antibiotic and antiprotozoal agent metronidazole (MTZ), which is known to induce reversible male infertility. Two doses of RA (5 and 15mg kg-1) were studied in sexually mature rats with and without MTZ-induced infertility. Rats were intraperitoneally injected with 5mg kg-1 RA or 15mg kg-1 RA (in distilled water) and, 45min later, they were intraperitoneally injected with 40mg kg-1 MTZ (in distilled water). Cauda epididymidal sperm suspensions were used to assess sperm count, motility and morphology. Histological and ultrastructural studies were performed on the testes and cauda epididymidis. In rats in which infertility was not induced, neither dose of RA affected the parameters assessed. However, in sexually mature rats in which infertility was induced by 40mg kg-1 MTZ, RA at both 5 and 15mg kg-1 ameliorated the damaging effects of MTZ on final bodyweight (30 days later), sperm motility and morphology. Only 5mg kg-1 RA, and not 15mg kg-1 RA, improved the harmful effects of MTZ on the sperm count and testis ultrastructure. The findings of the present study have considerable clinical implications and suggest a possible use for RA to reverse the negative effects of MTZ on male fertility, the male reproductive system and spermatogenesis.
