Knowledge, attitudes, ethical and social perspectives towards fecal microbiota transplantation (FMT) among Jordanian healthcare providers.

BACKGROUND: Fecal microbiota transplant (FMT) is a treatment modality that involves the introduction of stool from a healthy pre-screened donor into the gastrointestinal tract of a patient. It exerts its therapeutic effects by remodeling the gut microbiota and treating microbial dysbiosis-imbalance. FMT is not regulated in Jordan, and regulatory effort for FMT therapy in Jordan, an Islamic conservative country, might be faced with unique cultural, social, religious, and ethical challenges. We aimed to assess knowledge, attitudes, and perceptions of ethical and social issues of FMT use among Jordanian healthcare professionals. METHODS: An observational, cross-sectional study design was used to assess knowledge, attitudes, and perceptions of ethical and social issues of FMT among 300 Jordanian healthcare professionals. RESULTS: A large proportion (39 %) thought that the safety and efficacy of this technique are limited and 29.3 % thought there is no evidence to support its use. Almost all (95 %) responded that they would only perform it in certain cases, if ethically justified, and 48.3 % would use it due to treatment failure of other approaches. When reporting about reasons for not using it, 40 % reported that they would not perform it due to concerns about medical litigation, fear of infections (38 %), and lack of knowledge of long safety and efficacy (31.3 %). Interestingly, all practitioners said they would perform this procedure through the lower rather than upper gastrointestinal tract modality and the majority will protect the patient's confidentiality via double-blinding (43.3 %). For a subset of participants (n = 100), the cultural constraints that might affect the choice of performing FMT were mainly due to donor's religion, followed by dietary intake, and alcohol consumption. CONCLUSIONS: Our healthcare practitioners are generally reluctant to use the FMT modality due to religious and ethical reasons but would consider it if there was a failure of other treatment and after taking into consideration many legislative, social, ethical and practice-based challenges including safety, efficacy and absence of guidelines.

COVID-19: Between Past and Present.

Since the WHO declared coronavirus disease 2019 (COVID-19) as a pandemic, huge efforts were made to understand the disease, its pathogenesis, and treatment. COVID-19 is caused by severe acute respiratory syndrome (SARS) coronavirus-2 (SARS-CoV2), which is closely related to SARS-associated coronavirus (SARS-CoV). This article attempts to provide a timely and comprehensive review of the coronaviruses over the years, and the epidemics they caused in this century with a focus on the current pandemic COVID-19. It also covers the basics about the disease immunopathogenesis, diagnosis, prognosis, and treatment options. Although almost every single week new clinical findings are published, which change our understanding of COVID-19, this review explores and explains the disease and the treatment options available so far. In summary, many therapeutic options are being investigated to treat and/or ameliorate the symptoms of COVID-19, but none is registered and no sufficient data to support immune-based therapy beyond the context of clinical trials. For that, strengthening our immune system is the best defense at this time.

Oral contraceptive and breast cancer: do benefits outweigh the risks? A case - control study from Jordan.

BACKGROUND: Oral contraceptives (OCs) use has been linked to increased risk of breast cancer (BC) in several reports from the world. Limited number of similar studies have been conducted in the Middle Eastern female population. This study aimed to explore any possible correlation between the contemporary and duration of OCs use among Jordanian women and the risk of breast cancer. METHODS: A case control study was conducted in 450 Jordanian women (225 as cases and 225 as controls), aged 18 to 65. Chi-square test was used to study the association between risk of breast cancer and different factors. Mann Whitney-U test was employed to evaluate the relation between time-dependent risk factor and breast cancer. RESULTS: Our results indicated that regular use of OCs exhibited association with increased risk of breast cancer (OR = 2.25, 95% CI 1.34-2.79; p = 0.002), while the duration of OCs use was not associated with the increased risk of breast cancer (p > 0.05). In addition, other factors demonstrated significant association with the increased risk of breast cancer such as age at puberty, age at menopause, previous pregnancies, menopausal status, and family history of cancer. CONCLUSIONS: regular use of OCs may be associated with increased risk of breast cancer in Jordanian women. A larger sample size in multi-center setting study is required to confirm this finding among the Jordanian female population.

Impediments to use of oral contraceptives among refugee women in camps, Jordan.

OBJECTIVES: This study aimed to assess factors related to oral contraceptive (OC) use among refugee married women in the age range 18-50 years, residing in refugee camps in Jordan. METHODS: A face-to-face questionnaire was completed by 425 women, who had used OCs at least once in their lifetime as a contraceptive method. Data were collected between November 2016 and January 2017. RESULTS: About 45 percent of women preferred OCs as a contraceptive method. Most (80 percent) women thought OCs were effective, while 68.5 percent were concerned about their safety. About 10.6 percent women became pregnant while using OCs, and 75 percent reported side effects, specifically headache (54.6 percent), irritability (46.4 percent), mood swings (39.1 percent), and weight gain (30.6 percent). However, only 21.2 percent of participating women reported that they knew how to use OCs. Alarmingly, 85.9 percent of women reported that they skipped the OC pill when they missed using it. Knowledge about correct use was directly correlated with education, number of pregnancies and children, and duration of OC use. CONCLUSION: Women residing in refugees' camps in Jordan had relative unwillingness to use OCs. Although they tended to use them appropriately and had fair experience with their use, large gaps in their knowledge were apparent.

The impact of clinical pharmacists in improving Jordanian patients' health outcomes.

OBJECTIVES: To assess the impacts of clinical pharmacists on Jordanian patients' health outcomes. Methods: A systematic review was conducted until July 2016 within EBSCO, Pubmed, Cochrane database, and ISI Web of Knowledge. Published studies evaluating the benefit of clinical pharmacy services on therapeutic, safety, humanistic, and economic outcomes in hospital or community settings in Jordan were targeted. Two reviewers independently extracted and assessed risk of bias using a pre-published validated tool. The literature search identified 130 publications of which 21 full texts met predetermined inclusion criteria. Results: Studies were of moderate quality. Pharmacist interventions resulted in an average reduction (95% CI) in systolic blood pressure of 5.45 mm Hg (2.95-7.92) and diastolic blood pressure of 3.03 mm Hg (1.09-4.96). The mean reduction in glycosylated hemoglobin was 0.75% (-0.49-1.99) and fasting blood sugar was 36.73 mg/dl (-19.7-93.1). The average reduction in low-density lipoprotein cholesterol was 2.36 (1.8-16.62) mg/dl and triglycerides was 20.16 (6.14-46.47). There was a minimal increase in the level of high-density lipoprotein cholesterol of 1.24 (1.64-4.11) mg/dl. Effects on safety along with humanistic and economic outcomes and long term effects remained unclear.  Conclusion: Published evidence from Jordan highlights service opportunities for clinical pharmacists. Favorable but not always statistically significant impacts were found on therapeutic outcomes. More studies are needed to understand safety, humanistic, economic, and long-term outcomes. Therefore, the add-on benefits of this service to the health system are not well understood. Future studies of higher rigor and multi-perspective outcomes are mandated.

Current knowledge, attitude, and patterns of oral contraceptives utilization among women in Jordan.

BACKGROUND: Studies exploring the knowledge, attitude and patterns of OCs use among women in Jordan are lacking. The aim of this study was to assess knowledge, attitude, and patterns of oral contraceptives (OCs) utilization among women in Jordan. METHODS: A face-to-face questionnaire inquiring demographic information and issues related to knowledge and use of OCs was completed by women (n = 1571), who have had used OCs at least once in their lifetime. A model was created to assess the effects of knowledge, attitude and previous experience on the patterns of OCs utilization. RESULTS: Jordanian women exhibited positive attitudes towards OCs efficacy and safety. This positive attitude was approvingly associated with the patterns of use. However, only half of participating women reported that they knew how to use OCs. About 60% of women received recommendations for OCs use from a physician. Moreover, women's knowledge about OCs mechanism of action was obtained namely from physician (29.9%). Side effects were reported in 75.1% of participating women. Reported side effects were headache (41.2%), mood swings (35.5%), irritability (33.5%) and weight gain (28.7%). Interestingly, the occurrence of side effects was the main reason for OCs discontinuation. CONCLUSION: The study showed that women who have positive attitude toward OCs tend to utilize them more appropriately. However, there is still need for educational programs to enhance knowledge about OCs utilization in Jordan.

The Role of Megalin in the Transport of Gentamicin Across BeWo Cells, an In Vitro Model of the Human Placenta.

Aminoglycosides (AG) are known to readily cross the placenta, although the mechanisms responsible for placental transport have not been characterized. Megalin is expressed in human placenta, and it is reasonable to speculate, given its role in renal AG uptake, that it is similarly involved in placental transport. However, the role of megalin in placental AG uptake has not been established. An in vitro model to study megalin-mediated placental transport has also not been previously described. The objectives of this study, therefore, were to evaluate the human choriocarcinoma (BeWo) cell line as a model to study megalin-mediated placental transport and to assess the uptake kinetics of gentamicin, an AG antibiotic, using this in vitro model. BeWo cells were grown on Transwell® plates, and megalin expression and functional activity were assessed. Uptake of (3)H-gentamicin was also evaluated in the presence and absence of megalin inhibitors. Expression of megalin protein and mRNA in BeWo cells were confirmed via immunoblot and qPCR analysis. Uptake of fluorescein isothiocyanate (FITC)-labeled bovine serum albumin (BSA) (a megalin substrate) was time-, concentration-, and temperature-dependent consistent with a transporter-mediated process. FITC-BSA uptake was also significantly reduced in the presence of unlabeled gentamicin (a megalin substrate) and sodium maleate (to induce megalin shedding) suggesting that megalin is functionally active in BeWo cells. Gentamicin uptake exhibited time and temperature dependence, saturability and Michaelis-Menten kinetics, all of which suggest a transporter-mediated process. Gentamicin uptake was also significantly reduced in the presence of the megalin inhibitors RAP and EDTA suggesting that megalin is likely involved in gentamicin uptake.

Megalin expression in human term and preterm placental villous tissues: effect of gestational age and sample processing and storage time.

INTRODUCTION: The aims of this study were to characterize megalin expression in human term and preterm placental villous tissues and to assess the impact of gestational age and sample storage on receptor expression. METHODS: Placental tissue samples were collected from pregnant women undergoing term and preterm Cesarean deliveries. Placental villous tissues were used to quantify megalin protein and mRNA expression by western blotting and quantitative polymerase chain reaction (q-PCR), respectively. Stability of megalin expression was also evaluated under various processing and storage conditions. RESULTS: Megalin mRNA was detected in term and preterm placental villous tissues. Expression in early preterm samples was 6-fold higher than in late preterm and term samples. Refrigeration of processed term samples at 4°C for up to 18h had a slight impact on megalin mRNA expression with stored samples exhibiting mRNA levels approximately 1.5-fold lower than those frozen immediately after processing. A greater decrease in mRNA expression (up to 33-fold) was observed when processed samples were snap-frozen immediately and thawed at 4°C. Processing of samples prior to refrigeration also appeared to improve mRNA stability with significantly higher expression levels noted in processed vs. unprocessed samples at all points for up to 48h. DISCUSSION: These data suggest that expression of megalin mRNA in term placental villous tissue is relatively stable for up to 18h when samples are processed immediately and refrigerated at 4°C prior to freezing. Processing prior to storage also appears to improve mRNA stability. This paper demonstrates the practical feasibility of analyzing stored tissue samples, thus, it will help with placental mRNA analysis. Additionally, megalin expression appears to vary inversely with gestational age with the greatest expression noted in the most premature samples. Age-dependent differences in placental megalin may therefore influence fetal exposure.

Receptor-mediated endocytosis across human placenta: emphasis on megalin.

Receptor-mediated endocytosis plays an important role in the maternal-fetal transport of various nutrients and drugs across human placenta. Megalin, a 600 kDa endocytic receptor, is expressed in placental syncytiotrophoblasts and is thought to contribute to the transport functions of the placenta. However, the molecular mechanisms involved in megalin-mediated transplacental transport of most substrates have not yet been characterized. Megalin is most extensively expressed on the apical surface of renal proximal tubular epithelial cells, where it is involved in the reabsorption of proteins, vitamins, and polybasic drugs including aminoglycoside (AG) antibiotics. It has been suggested that megalin-mediated endocytosis is primarily responsible for accumulation of aminoglycosides (AGs) in the renal proximal tubule, which results in direct cellular injury and death. The role of megalin in the renal uptake and accumulation of aminoglycosides has therefore received much attention. It is not known, however, whether megalin is involved in the maternal-fetal transport of AGs and other commonly used polybasic drugs. Studies designed to characterize the role of megalin in transplacental transport and to understand the molecular mechanisms involved in megalin-mediated endocytosis across human placenta are therefore needed.
