Quality of Life among Renal Transplant Recipients in Bahrain: A Single-Center Experience.

Although a positive effect of renal transplantation on quality of life (QOL) scores was demonstrated in numerous international studies, there are a few studies in renal transplant recipients in Arabic countries. The purpose of this study was to assess the QOL in renal transplant recipients in Bahrain. We used the standard QOL Index (QOLI) score instrument in Arabic languages. This study included 58 patients, aged 26-71 years, and 63.8% of them were males. We excluded patients below 18 years old and failed renal transplant at the time of the study. The highest QOL score was in the psychological/spiritual domain (87.4 ± 12.2), followed by the family domain (85.5 ± 13.1), the health and functioning domain (82.7 ± 13.3), and the social and economic domain (80.5 ± 13.9). There was a highly significant high positive correlation between the QOLI and each of the tested domains (P <0.001). Married participants had a significantly higher QOL score in the family domain, compared to unmarried participants (P = 0.025). The QOL scores in the health and functioning domain were significantly affected by the patient's social status, residence, and coexisting diabetes mellitus. In addition, the QOLI scores were significantly greater among patients who did their transplants in Bahrain (P = 0.045). Most of the renal transplant patients in Bahrain are satisfied with their QOL. Their QOL was also variably impacted by the different sociodemographic and clinical factors.

A toolbox for conducting an online OSCE.

This toolbox highlights the lessons learned and the tools used to run the online OSCE at the College of Medicine and Medical Sciences, Arabian Gulf University (CMMS-AGU) using Zoom™ï¸. The examiners considered the examination to be valid in assessing all clinical skills except for psychomotor skills and students found it to be highly acceptable. We describe three phases. Planning and preparation phase in which situation analysis, aligning stakeholders, mobilizing resources, creating a shared vision, and ownership of the exam project take place. For successful implementation of examinations, detailed plans are needed including manpower, timings, number of stations and detailed description of the steps of the examination process. We provide a set of guiding questions for proper decision making related to online clinical exams. Implementation Phase in which piloting is very useful to apply improvements to the original plan and to outline the needed capacity building of the participating staff. We give a detailed description of the guiding documents, means of communication and features of ZOOM that were used. Evaluation phase we provide a guide for evaluating the process and outcome, including a list of key performance indicators.

Validating the modified System for Evaluation of Teaching Qualities: a teaching quality assessment instrument.

CONSTRUCT: We assessed the validity of the modified System for Evaluation of Teaching Qualities (mSETQ) in evaluating clinical teachers in Bahrain. BACKGROUND: Clinical teacher assessment tools are essential for improving teaching quality. The mSETQ is a teaching quality measurement tool, and demonstrating the validity of this tool could provide a stronger evidence base for the utilization of this questionnaire for assessing medical teachers in Bahrain. APPROACH: This study assessed the construct validity of this questionnaire in medical schools across Bahrain using 400 medical students and 149 clinical teachers. Data were analyzed using confirmatory factor analysis (CFA). The goodness-of-fit index (GFI), comparative fit index (CFI), root mean square residual, and standardized root mean square error of approximation (RMSEA) indices were used to evaluate the model fit. The internal consistency reliability was assessed using Cronbach's alpha. RESULTS: The results of the CFA revealed an acceptable fit. All criteria for a good model fit were met except for the RMSEA fit index and the standardized root mean square residual (SRMR) value, which was very close to an acceptable value. Good overall reliability was found in the study (α=0.94). CONCLUSION: The overall findings of this study provided some evidence supporting the reliability and validity of the mSETQ instrument.

The high-molecular weight multimer form of adiponectin is a useful marker of polycystic ovary syndrome in Bahraini Arab women.

BACKGROUND & AIMS: We tested if decreased total and high molecular weight (HMW)-adiponectin, and altered HMW/total adiponectin ratio (HMWR) constitute reliable markers of polycystic ovary syndrome (PCOS) among Bahraini Arab women. METHODS: Case-control study involving 122 Bahraini Arab women with PCOS and 89 ethnically-matched control women. PCOS was evaluated according to 2003 Rotterdam criteria. Total and HMW-adiponectin were measured by ELISA. RESULTS: Compared to controls, women with PCOS had significantly reduced plasma HMW-adiponectin, and HMWR, more so than total adiponectin. Logistic regression analysis revealed that HMW-adiponectin and HMWR, more than total adiponectin, were negatively associated with PCOS. ROC area-under-the-curve for predicting PCOS were larger for HMW-adiponectin (0.679 ± 0.037), and HMWR (0.653 ± 0.039), than total adiponectin (0.537 ± 0.041). Regression analysis confirmed the association of low HMW-adiponectin and HMWR with PCOS. HMW-adiponectin and HMWR inversely correlated with age, BMI, hirsutism, insulin, HOMA-IR, and positively correlated with serum LDL-cholesterol. Total adiponectin was negatively correlated with waist-hip ratio and serum LH levels. CONCLUSIONS: Reduction in adiponectin plasma levels is an independent risk factor for PCOS. Changes in HMW-adiponectin serum levels and HMW/total adiponectin ratio are better markers for the presence of PCOS, when compared with total adiponectin.

Leutinizing hormone/choriogonadotropin receptor and follicle stimulating hormone receptor gene variants in polycystic ovary syndrome.

PURPOSE: Previous studies identified follicle-stimulating hormone receptor (FSHR) and luteinizing hormone/choriogonadotropin receptor (LHCGR) genes as polycystic ovary syndrome (PCOS) susceptibility loci, which was dependent on the racial/ethnic background of studied population. We investigated the association of genetic variants in FSHR and LHCGR with PCOS in Bahraini Arab women. METHODS: A retrospective case-control study, involving 203 women with PCOS, and 211 age- and ethnically-matched control women. FSHR and LHCGR genotyping was done by allelic exclusion method (real-time PCR). RESULTS: Significantly lower frequencies of heterozygous LHCGR rs7371084 and FSHR rs11692782 genotype carriers were seen between women with PCOS vs. controls, and increased frequency of heterozygous homozygous LHCGR rs4953616 genotype carriers were detected between women with PCOS compared to control women. Limited linkage disequilibrium was noted among LHCGR and FSHR SNPs, and 2 blocks were constructed: the first (Block 1) spanning 61 kb contained the six tested LHCGR SNPs, and the second (Block 2) spanning 298 kb contained four of the five tested FSHR SNPs. Higher frequency of LHCGR GTCAAG haplotype was seen in women with PCOS compared to controls; the frequencies of the remaining LHCGR haplotypes, and all FSHR haplotypes were similar between cases and controls. CONCLUSION: This is the first study to confirm the association of novel LHCGR (rs7371084, rs4953616) and FSHR (rs11692782) SNPs with PCOS. The differential association of LHCGR and FSHR variants with PCOS confirms the racial/ethnic contribution to their association with PCOS.

DENND1A gene variants in Bahraini Arab women with polycystic ovary syndrome.

Recent genome-wide association studies and replication analyses reported an association between variants of DENND1A gene and polycystic ovary syndrome (PCOS), mostly in Asians. We therefore examined whether the common DENND1A SNPs rs10818854, rs2479106, and rs10986105 are associated with PCOS in Bahraini Arab population. This case-control study involved 191 women with PCOS diagnosed according to the Rotterdam criteria, and 202 control women. SNP genotyping was performed by the allelic discrimination in real-time PCR. The outcome was that the minor allele frequencies of SNPs rs10818854, rs2479106, and rs10986105 were similar between women with PCOS and control women (P>0.05), even before correcting for multiple testing, and none of the tested DENND1A SNPs were associated with PCOS under co-dominant, dominant, or recessive genetic models. None of the tested DENND1A variants were associated with PCOS features (hirsutism, insulin sensitivity, menses pattern, free testosterone, and free androgen index). Taking common GTA haplotype as reference (OR=1.00), [rs10818854/rs2479106/rs10986105] 3-locus haplotype analysis demonstrated lack of association of any of the DENND1A haplotypes with PCOS, even before correcting for multiple testing. To conclude we demonstrated lack of association of DENND1A SNPs rs10818854, rs2479106, and rs10986105, previously associated with PCOS in Asians, with PCOS in Bahraini Arab women.

Association of selective HLA class II susceptibility-conferring and protective haplotypes with type 2 diabetes in patients from Bahrain and Lebanon.

The association of HLA class II with type 2 diabetes (T2DM) was investigated in Bahraini and Lebanese subjects. DRB1*070101 (Lebanese and Bahraini) and DQB1*0201 (Lebanese) were susceptibility-conferring alleles, and unique susceptibility-conferring/protective haplotypes were found in both patient groups. Regression analysis confirmed that DRB1*070101-DQB1*0201 (Bahraini) and DRB1*110101-DQB1*0201 (Lebanese) were susceptibility-conferring haplotypes.

Comparison of palpation-guided versus ultrasound-guided fine-needle aspiration biopsies of thyroid nodules in an outpatient endocrinology practice.

OBJECTIVE: To investigate the role of thyroid ultrasonography in our outpatient endocrine practice. METHODS: We compared the efficacy of ultrasound-guided fine-needle aspiration biopsy (US-FNAB) of thyroid nodules with that of palpation-guided aspiration (P-FNAB) and determined the malignancy rates of palpable and nonpalpable nodules. All patients referred for assessment of thyroid nodular disease from October 1997 through August 2001 were included in the study. Fine-needle aspirations were performed by palpation guidance until October 1999, after which US-FNAB was exclusively performed. All thyroid examinations, ultrasound imaging, and aspiration biopsies were performed by the same endocrinologist in an office-based setting. Histopathologic and cytologic diagnoses were compared for patients who underwent thyroidectomy. RESULTS: A total of 376 nodules in 276 patients were aspirated during a 47-month period. P-FNAB was used on 157 nodules, and US-FNAB was performed on 219 nodules (both procedures were done on 21 nodules). For palpable thyroid nodules that were resected, the cytologic diagnostic accuracy rate was 60.9% and 80% for P-FNAB and US-FNAB, respectively. With use of ultrasound guidance, the sensitivity, positive predictive value, and negative predictive value increased significantly. In addition, the inadequate specimen rate decreased from 11.2% in the P-FNAB group to 7.1% in the US-FNAB group. Among the nodules that were not palpable, the malignancy rate was similar to that for the palpable thyroid nodules (5.1% versus 6.8%). CONCLUSION: US-FNAB improved the cytologic diagnostic accuracy, sensitivity, and positive predictive value and reduced the false-negative rate in comparison with P-FNAB. The malignancy rate for nonpalpable thyroid nodules was similar to that for palpable nodules.

Contribution of selective HLA-DRB1/DQB1 alleles and haplotypes to the genetic susceptibility of type 1 diabetes among Lebanese and Bahraini Arabs.

CONTEXT: Human leukocyte antigen (HLA) class II genes contribute to the genetic susceptibility of type 1 diabetes (T1D), and both susceptible and protective alleles were implicated with its pathogenesis, which varies among various ethnic/racial groups. OBJECTIVE: This study investigated the heterogeneity in HLA class II haplotypes distribution among Bahraini and Lebanese T1D patients. DESIGN: This was a cross-sectional retrospective study. SETTING: The study was conducted at primary care private and public health centers. PATIENTS AND OTHER PARTICIPANTS: Subjects comprised 126 T1D patients and 126 healthy controls from Bahrain and 78 Lebanese T1D patients and 111 control subjects. INTERVENTION(S): There were no interventions. RESULTS: Although Lebanese and Bahraini patients share DRB1*030101, DQB1*0201 as susceptible and DRB1*100101 and DQB1*030101 as protective alleles, DRB1*040101 was an additional susceptible allele in Bahraini patients, and DRB1*130701 and DQB1*050101 were additional susceptible and protective alleles in Lebanese, respectively. DRB1*030101-DQB1*0201 was susceptible, whereas DRB1*070101-DQB1*0201 and DRB1*110101-DQB1*030101 were protective haplotypes in Bahraini and Lebanese. DRB1*040101-DQB1*0302 and DRB1*040101-DQB1*050101 displayed different associations: they were protective in Lebanese but susceptible or neutral among Bahrainis. Whereas the frequency of homozygous DRB1*03011-DQB1*0201 was higher in Bahraini and to a lesser extent Lebanese patients, homozygous DRB1*110101-DQB1*030101 was significantly more frequent in Lebanese but not Bahraini controls, whereas DRB1*030101-DQB1*0201/DRB1*040101-DQB1*0201 was the major genotype among Bahraini patients but not Lebanese subjects in whom it was present at very low frequencies. CONCLUSION: In view of these differences between Bahraini and Lebanese, this demonstrates that the contribution of HLA class II to the genetic susceptibility to T1D must be evaluated with regard to specific HLA haplotypes and also ethnic origin and racial background.

Susceptible and protective human leukocyte antigen class II alleles and haplotypes in bahraini type 2 (non-insulin-dependent) diabetes mellitus patients.

Whereas the genetic risk for type 1 diabetes is linked to human leukocyte antigen (HLA) class II genes, the HLA association in type 2 (non-insulin-dependent) diabetes is less clear. The association between HLA class II genotypes and type 2 diabetes was examined in adult Bahrainis, an Arab population with a high prevalence of type 2 diabetes. HLA-DRB1* and -DQB1* genotyping of 86 unrelated type 2 diabetes patients (age, 51.6+/-8.2 years; mean duration of diabetes, 7.7+/-7.1 years) who had a strong family history of diabetes (52 of 72 versus 0 of 89 for controls, P<0.001) and 89 healthy subjects was done by PCR-sequence-specific priming. DRB1*040101 (0.1221 versus 0.0562, P=0.019) and DRB1*070101 (0.2151 versus 0.0843, P<0.001) were positively associated, while DRB1*110101 (0.0698 versus 0.1461, P=0.014) and DRB1*160101 (0.0640 versus 0.1236, P=0.038) were negatively associated with type 2 diabetes. DRB1*040101-DQB1*0302 (0.069 versus 0.0007; P=0.004), DRB1*070101-DQB1*0201 (0.178 versus 0.0761, P=0.007), DRB1*070101-DQB1*050101 (0.125 versus 0.0310, P=0.002), and DRB1*150101-DQB1*060101 (0.0756 versus 0.0281, P=0.008) were more prevalent among patients, while DRB1*160101-DQB1*050101 (0.0702 versus 0.0349, P=0.05) was more prevalent among controls, conferring disease susceptibility or protection, respectively. In Bahrainis with type 2 diabetes, there is a significant association with select HLA class II genotypes, which were distinct from those in type 1 diabetes.

Dramatic improvement of BMD following vitamin D therapy in a bone marrow transplant recipient.

Bone marrow transplantation is now an established successful treatment for several hematologic malignancies. Bone loss is among the long-term adverse effects of this procedure. The underlying pathophysiology is believed to be multifactorial. We report a case of osteoporosis in a young patient who underwent allogenic bone marrow transplantation for acute lymphoblastic leukemia that was complicated by intestinal graft-versus- host disease. Her bone density measurement showed T-scores of -3.46 and -2.47 in the lumbar spine and femoral neck respectively. On evaluation, she had low normal serum calcium, low urine calcium, low 25- hydroxyvitamin D, elevated total and bone specific alkaline phosphatases, and elevated parathyroid hormone. Following treatment with calcifediol, the biochemical markers normalized and the bone mineral density increased by 88% in the lumbar spine and almost 60% in the femoral neck, both of which were above the mean for her age group. We believe that the graft-versus-host disease caused a malabsorptive state that led to vitamin D deficiency and possible resistance and consequent osteomalacia.
