RESUMO

BACKGROUND: Phenylketonuria (PKU) is the most frequent inborn error in amino acid metabolism caused by a deficiency of the phenylalanine hydroxylase enzyme (PAH). If PKU is left untreated, high concentrations of phenylalanine (Phe) accumulate in the blood, leading to severe brain dysfunction, neurodevelopmental, behavioral and psychological problems. Data concerning the epidemiology of PKU in Jordan are limited. The main objectives of our study were to determine the prevalence of PKU in Jordan, analyze the PKU phenotypes, and identify major challenges in providing dietary management to PKU patients. METHODS: Data were collected utilizing the medical records of PKU patients attending the PKU clinic at the Ministry of Health in Amman, Jordan, between 2008 and 2021. RESULTS: The total number of patients diagnosed with PKU was 294. The prevalence of PKU was estimated to be 1/5263. Most patients were Jordanians (90.8%), and 9.2% were non-Jordanians. More than half of the patients (56%) were diagnosed through the national newborn screening (NBS) program. Regarding the phenotypes of PKU, 46.6% had moderate PKU, whereas 42.9% had the classic type of PKU and only 8 (2.7%) had cofactor Tetrahydrobiopterin (BH4) deficiency (atypical PKU). According to the age of diagnosis, 66% of patients were diagnosed more than 30 days post-birth. Consanguinity was found in 87.4% of patients, and the majority of patients, 218 (74.2%), had first-degree consanguinity. The most common complication was mental retardation (31%). Most patients were committed to dietary management (83%) and developed fewer complications. CONCLUSION: In our study, we demonstrated the importance of the NBS program in the early identification and diagnosis of new PKU cases which allows the initiation of treatment and dietary management to prevent severe complications of PKU in Jordan.

RESUMO

Background: Population-based serosurveillance is a cornerstone to furthering our understanding of the COVID-19 pandemic at the community levels. In Jordan, four waves (phases) of seroprevalence epidemiological investigations were conducted using representative population-based national samples. This study aims to estimate the population-based seropositivity, herd immunity, and vaccination coverage at the fourth wave. Methods: Multistage sampling technique was implemented to recruit a nationally representative sample for the fourth wave of the seroprevalence investigation (June to August 2021). Electronically collected data utilized a questionnaire on background demographics, chronic diseases, and COVID-19 vaccination history. Also, blood samples were collected to detect the presence of total Anti-SARS-CoV-2 IgM and IgG using Wantai/ELISA assays. Prevalence estimates were presented using percentage and 95% Confidence Intervals (C.I.). Results: There were 8821 participants included in this study, with a mean age of 31.3 years, and 61.7% were females. COVID-19 national seroprevalence and vaccination coverage estimates were 74.1% (95% C.I.: 73.1-74.9%) and 38.4% (95% C.I.: 37.1-39.6%), respectively. Among children, seroprevalence estimates were similar to unvaccinated adults. Among COVID-19 adults, 57.2% were vaccinated. Among vaccinated participants, 91.5% were seropositive, while among unvaccinated, 63.2% were seropositive. By age group, seroprevalence ranged between 53.0% and 86.9%. Seroprevalence estimates were significantly different by gender, vaccination status and dose, and residence. Conclusion: The reported interplay between seropositivity and vaccination coverage estimate seems insufficient to provide herd immunity levels to combat new variants of SARS-CoV-2. Children and healthcare workers seem to be an epidemiologically influential group in spreading COVID-19. As the globe is still grappling with SARS-CoV-2 infection, national seroepidemiological evidence from Jordan calls for more focus on vaccination coverage, especially among epidemiologically vulnerable groups, to optimize herd immunity.

RESUMO

BACKGROUND: Despite under-reporting, health workers (HWs) accounted for 2 to 30% of the reported COVID-19 cases worldwide. In line with data from other countries, Jordan recorded multiple case surges among HWs. METHODS: Based on the standardized WHO UNITY case-control study protocol on assessing risk factors for SARS-CoV-2 infection in HWs, HWs with confirmed COVID-19 were recruited as cases from eight hospitals in Jordan. HWs exposed to COVID-19 patients in the same setting but without infection were recruited as controls. The study lasted approximately two months (from early January to early March 2021). Regression models were used to analyse exposure risk factors for SARS-CoV-2 infection in HWs; conditional logistic regressions were utilized to estimate odds ratios (ORs) adjusted for the confounding variables. RESULTS: A total of 358 (102 cases and 256 controls) participants were included in the analysis. The multivariate analysis showed that being exposed to COVID-19 patients within 1 metre for more than 15 minutes increased three-fold the odds of infection (OR 2.92, 95% CI 1.25-6.86). Following IPC standard precautions when in contact with patients was a significant protective factor. The multivariate analysis showed that suboptimal adherence to hand hygiene increased the odds of infection by three times (OR 3.18; 95% CI 1.25-8.08). CONCLUSION: Study findings confirmed the role of hand hygiene as one of the most cost-effective measures to combat the spreading of viral infections. Future studies based on the same protocol will enable additional interpretations and confirmation of the Jordan experience.

RESUMO

The evolution of the COVID-19 pandemic in Jordan during the first 10 months of the epidemic was peculiar and can be easily categorized in three different phases: a first period featuring a very low number of reported cases, a second period with exponential growth from August with up to 8000 cases on the 18th November 2020, and a third phase with steady and progressive decline of the epidemiological curve. With the aim of better determine the entity of the population exposed to SARS-CoV-2, the Jordan Ministry of Health with the support of the WHO launched three rounds of the nationwide sero-prevalence survey. Using population proportionate to size (PPS) methodology, around 5000 individuals were selected from all Jordan governorates. Blood samples were collected from all participants and ELISA assays for total IgM, IgG antibodies to COVID-19 were used for testing at the National Public Health Laboratory. Results revealed that seroprevalence dramatically increased over time, with only a tiny fraction of seropositive individuals in August (0.3%), to increase up to more than 20-fold in October (7.0%) and to reach one-third of the overall population exposed by the end of 2020 (34.2%). While non age-specific trends were detected in infection rates across different age categories, in all three rounds of the seroprevalence study two out of three positive participants did not report any sign and/or symptom compatible with COVID-19. The serial cross-sectional surveys experience in Jordan allowed to gain additional insights of the epidemic over time in combination with context-specific aspects like adherence to public health and social measures (PHSM). On the other hand, such findings would be helpful for planning of public health mitigation measures like vaccinations and tailored restriction policies.

RESUMO

Background: Knowledge, attitudes and practices of health care professionals towards pharmacovigilance are strongly associated with reporting adverse drug reactions, as proven by a number of studies. This study aims to evaluate the levels of knowledge, attitudes and practices towards pharmacovigilance among physicians working at health centres of the Jordanian Ministry of Health. Methods: This took the form of a cross-sectional survey. Questionnaires were distributed by the researcher and research assistant to the physicians. Twenty primary and comprehensive health centres were covered. Results: The study included 106 physicians. Poor knowledge and practices were observed (mean knowledge score of 1.5±1.2 out of five, and mean practice score of 5.5±1.8 out of 15), while a high level of positive attitudes was observed (mean attitude score of 9.3±1.3 out of 10). Half of the physicians were aware that monitoring adverse drug reactions in Jordan is carried out by the Jordan Pharmacovigilance Centre. The majority of physicians (95.2%) mentioned that they rarely or never used the adverse drug reactions reporting form in Jordan. Conclusions: It is clear that there is a need to initiate educational activities and intervention programmes to raise the awareness of health care providers in Jordan regarding pharmacovigilance.

RESUMO

OBJECTIVES: This study aimed to determine the overall incidence, trend, and epidemiology of cancer among Jordanians from 2000 to 2013 using data extracted from Jordan's Cancer Registry (JCR). METHODS: All cancer cases among Jordanians registered between 2000 and 2013 were analyzed using CanReg software and SPSS. The overall crude incidence rates (CIRs) and the age standardized rates (ASRs) of cancer per 100,000 were calculated. RESULTS: A total of 58788 cancer cases were registered during the period 2000-2013. Of those, 28545 (48.6%) were males and 30243 (51.4%) were females. About three-quarters (77.3%) of the registered patients were ≥ 40 years in age. Overall, the average crude cancer incidence rate was 82.8/100,000 population during the 14-year study period. On the other hand, the ASR was 126/100,000 during the same period (124.2 /100,000 for males and 128.4 /100,000 for females). The cumulative top cancers among males were colorectal, lung, lymphoma, urinary bladder, and prostate, respectively, while those among females were breast, colorectal, lymphoma, thyroid, and uterine. The number of cancer cases has increased from 3370 in 2000 to 5409 in 2013 (60.5% increase over the 14 years). The percentage of increase was 68.4% in females and 52.5% in males. The ASR has also increased from 113.6 per 100,000 in 2000 to 142.1 per 100.000 in 2013 with a 25.1% of increase during the 14 years. CONCLUSION: Over the 14-year study period, incidence of cancer in Jordan has increased. However, it remains lower than that in other Eastern Mediterranean and Western countries. We recommend initiating screening programs for the most common types of cancer in Jordan that have valid screening tests to detect cancer during its early stages and reduce overall morbidity and mortality.

RESUMO

Obesity, a chronic condition associated with several life-threatening diseases, affects a significant proportion of the global population and has long been associated with vitamin D deficiency. The prevalence of both obesity and vitamin D deficiency has increased dramatically in Jordan in recent decades, especially among women. Few studies in Jordan and the surrounding area address this issue. In this study, we hypothesize that calcium and vitamin D have beneficial effects on weight reduction and metabolic profile in obese women. The objective of this study is to examine the effect of vitamin D3 and calcium supplementation on anthropometric measurements and some blood metabolites. Forty-five obese female subjects with vitamin D deficiency were recruited by a dietitian and randomly assigned to the same weight loss diet in addition to the following treatments (4 groups): control (CON), no prescribed supplements; vitamin D3 (Diet/D), given a high weekly dose of cholecalciferol (50 000 IU/subject/week); calcium (Diet/Ca), given 1200 mg/dL calcium/subject/day; vitamin D3 plus Ca (Diet/Ca/D), given cholecalciferol (50 000 IU/subject/week) and calcium (1200 mg/dL calcium/subject/day). Results revealed that after 3 months of supplementation, the Diet/Ca/D group subjects experienced a significant reduction (P ≤ .05) in weight (10.49 kg), BMI (4.61 ± 2 kg/m2), waist circumference (11.41 ± 8.9 cm), body fat percentage (2.43 ± 1.7%), FBG (25.81 ± 11.4 mg/dL), PTH (27.58 ± 8.9 pg/mL), cholesterol (0.56 ± 0.2 mmol/L), and triglycerides (0.53 ± 0.21 mmol/L) when compared to the Diet/Ca and the CON groups. Interestingly, however, the CON group showed a significant increase in serum PTH concentration (9.51 ± 3.8 pg/mL, P ≤ .05). Based on these results, a combined Ca and vitamin D3 supplement appears to enhance weight loss and improve some of the blood metabolic profiles in obese women subjected to a weight loss diet, thus supporting our study hypothesis.

RESUMO

OBJECTIVES: To determine the incidence of cervical cancer in Jordan and assess its trend in over a 14-year period (2000-2013). METHODS: This descriptive study was based on secondary analysis of cervical cancer data that are registered in the Jordan Cancer Registry (JCR). RESULTS: A total of 591 women were diagnosed with cervical cancer in Jordan during the period 2000-2013. The age at diagnosis ranged between 15 and 97 years, with a median of 50 years. The average age standardized rate (ASR) was 2.0/100,000 women. The incidence of cervical cancer started to decrease after 2006 but it remained relatively constant between 2008 and 2013. Over the 14-year period, ASR for cervical cancer decreased by 28.6% from 2.1 per 100,000 women in 2000 to 1.5 per 100,000 women in 2013. About 46.5% of the cases were of squamous cell carcinoma morphology. Early cancer constituted about 60% of the cases, regional cases constituted 9.6%, and distant metastatic cases constituted 10.7%. CONCLUSIONS: The incidence of cervical cancer in Jordan is low compared to regional estimates and remained relatively constant between 2008 and 2013. Implementation of screening measures could lead to better case finding, early diagnosis, and prevention of cervical cancer.

RESUMO

Objectives. To estimate the survival rate of colorectal cancer (CRC) and determine its predictors among Jordanian patients who were diagnosed in the period of 2005-2010. Methods. This study was based on Jordan cancer registry. All CRC cases that were registered in cancer registry during 2005-2010 were analyzed using the survival analysis. The last date for follow-up was 1st Oct 2016. Results. A total of 3005 patients with CRC were registered during 2005-2010. The overall 5-year and 10-year survival rates for patients with CRC were 58.2% and 51.8%, respectively. The 5-year survival rate decreased significantly from 60.4% for the age <50 years to 49.3% for the age ≥70 years (p < 0.005). The 5-year survival rate was 72.1% for the localized stage, 53.8% for the regional stage, and 22.6% for the distant metastasis. In the multivariate analysis, the only factors that were significantly associated with survival were age, grade, stage, and location of tumor. Conclusions. The overall 5-year and ten-year survival rates for CRC were 58.2% and 51.8%, respectively. Increased age, poor differentiation, advanced cancer stage, and right-sided cancers were associated with lower survival rates. Screening strategies are needed for early detection of colon adenomas and colorectal cancer in Jordan.
