Pathological right ventricular changes in synthesized electrocardiogram in end-stage renal disease patients and their association with mortality and cardiac hospitalization: a cohort study.

BACKGROUND: Right ventricular (RV) function is an important prognostic predictor for end-stage renal disease (ESRD) patients. Non-invasive evaluation of RV function by simple electrocardiogram (ECG) is not yet evident. The purpose of this article was to investigate the presence and association of pathological right ventricular changes in synthesized ECG with cardiac hospitalization and mortality. METHODS: A prospective cohort study of 137 ESRD patients (mean age: 56 years) were recruited from the hemodialysis unit in An-Najah National University Hospital, Nablus, Palestine. Synthesized ECG was done right before the hemodialysis (HD) session. The pathological right ventricular changes were recorded for each patient. The relationship between pathological RV changes and mortality, cardiac and non-cardiac hospitalization was assessed through a 6-months follow-up period. RESULTS: Right ventricular Q wave was found in 2.2% of patients, while right ventricular ST elevation was found in 0.7% of patients, and right ventricular negative T wave was found in 0.7% of patients. During the 6-month period of follow-up, 36 (26.3%) patients were hospitalized, nine patients (6.6%) due to cardiac causes. A total of 8 (5.83%) patients died, out of those 4 patients (2.91%) due to cardiac causes. Using Fisher's exact test, there was a significant association between pathological abnormalities in synthesized ECG and hospitalization among hemodialysis patients, (p = 0.047). Pathological changes in synthesized ECG were less prevalent in non-cardiac hospitalizations than in cardiac hospitalizations. CONCLUSIONS: The presence of pathological RV synthesized ECG changes can predict cardiac hospitalization in ESRD patients. Synthesized ECG is a good available tool that can be easily performed in ESRD patients. To determine whether Synthesized ECG can be used as a screening tool for pathological RV changes in a dialysis patients, more research with a larger number of patients and a longer follow-up period is required.

Postpartum Depression in The Arab Region: A Systematic Literature Review.

BACKGROUND: Postpartum Depression (PPD) is a major public health problem affecting mothers and their babies. However, few studies have investigated the prevalence and risk factors for postpartum depression among Arab mothers. This systematic literature review aims to determine the prevalence of PPD among mothers in Arab countries and identify the main risk factors. METHODS: A review of all peer-reviewed journal published studies on PPD and its risk factors among Arab mothers until February 2016. The following data bases were searched; PubMed, Springlink, Science direct, EBSCOhost, and Arabpsychnet. RESULTS: 25 studies were included in the review. PPD rates were high in general but prevalences were close to the rates observed in other low and lower-middle-income countries. Twelve studies reported PPD prevalences in the region of 15-25%, 7 studies reported prevalences< 15% and 6 studies reported prevalences<25%. The most important risk factors for PPD were: low income and socioeconomic status, obstetric complications during pregnancy, unwanted pregnancy, ill infant, formula feeding, low social and husband support, marital and in-laws conflicts, stressful life events during pregnancy and personal or family history of depression. CONCLUSION: Prevalence of PPD is high in most Arab countries, with differences due in part to variations in methods of assessment. This review highlights the problem of PPD and advocates for the adoption of necessary changes in the Arab health systems such as routine screening and efficient referral systems in order to detect and treat this potentially debilitating condition.

Helicobacter pylori resistance to antibiotics at the An-Najah National University Hospital: a cross-sectional study.

BACKGROUND: Bacterial resistance to antibiotics is considered the most important determinant of treatment failure. Monitoring the evolution of antimicrobial resistance to common antibiotics is therefore of special importance for clinicians. The frequency of resistance to antibiotics in Helicobacter pylori isolates is increasing. The aim of this study was to determine the pattern of H pylori antibiotic resistance at the An-Najah National University Hospital. METHODS: In this cross-sectional study, we recruited patients older than 18 year who were admitted to the An-Najah National University Hospital. Participants underwent oesophageal gastroduodenoscopy and gastric biopsy in the hospital's laparoscopic department. Biopsies were taken from the gastric antrum and body during endoscope. The analysis of the biopsies included rapid urease test, histological examination to detect H pylori, and bacterial culture using selective media. After culturing the bacteria for 7 days, we tested oxidase, urease, and catalase activity. Cultures that were positive for H pylori were tested for their susceptibility to various antimicrobial agents. Ethical approval was obtained from the An-Najah National University before starting the data collection. All participants gave informed consent before the procedure. FINDINGS: Between July 1, 2016, and Jan 1, 2017, we enrolled 91 patients with dyspepsia (49 women and 42 men). 38 (42%) patients had an H pylori infection. H pylori was found in three (100%) of three patients with a duodenal ulcer, three (46%) of ten patients with a gastric ulcer, 20 (54%) of 37 patient with gastritis, and 12 (41%) of 29 patient with a normal endoscopic appearance. When isolates of H pylori isolates were subjected to sensitivity tests against six antibiotics, ciprofloxacin was the most effective drug against H pylori (0% resistance), followed by levofloxacin (0%), moxifloxacin (3%), and amoxicillin (18%). Metronidazole and clarithromycin were the least effective drugs, with resistance rates of 100% and 47%, respectively. INTERPRETATION: H pylori isolates from the Palestinian patients included in this study were highly resistant to the traditional first-line antibiotics clarithromycin and metronidazole. However, fluoroquinolones and amoxicillin are still effective antimicrobial choices. This could be the result of the unjustified wide use of antibiotics in the Palestinian community and the use of clarithromycin-based therapy as first-line treatment for H pylori, which in turn has led to increased rates of H pylori eradication failure. We recommend using quinolone-based regimens for H pylori and rationing the use of antibiotics in Palestinian patients. FUNDING: An-Najah National University.

Pulse versus daily oral Alfacalcidol treatment of secondary hyperparathyroidism in hemodialysis patients: a randomized controlled trial.

BACKGROUND: Secondary hyperparathyroidism is a common complication of chronic kidney disease and is managed using vitamin D replacement therapy. Very few studies have examined the effectiveness of pulse alfacalcidol therapy in comparison to daily oral alfacalcidol therapy in suppressing serum parathyroid hormone (PTH) levels in hemodialysis patients. The aim of this randomized controlled trial was to replicate the findings of prior studies comparing effectiveness of pulse oral alfacalcidol therapy versus daily oral alfacalcidol therapy in suppressing PTH after 13 weeks of therapy using a Palestinian sample of hemodialysis patients, and to identify demographic and biomedical characteristics of patients that are independently associated with PTH levels. METHODS: One hundred and sixty-seven patients completed the study, 88 in the daily group and 79 in the pulse group. The pulse group had more clinically significant reduction in mean PTH level by 75 pg/dL at 13 weeks than the daily group, but this was not statistically significant. RESULTS: The effect of alfacalcidol therapy on metabolism of phosphate and corrected calcium levels was comparable in both groups, and pulse therapy was not associated with increased risk of hypercalcemia and hyperphosphatemia. Serum PTH levels were independently and inversely associated with older age and diabetes. CONCLUSION: Switching daily alfacalcidol therapy to thrice-weekly alfacalcidol pulse therapy seems safe and convenient, especially for hemodialysis patients with poor compliance with treatment. This study also highlights the importance of monitoring and preventing malnutrition in hemodialysis patients and maintaining optimal glycemic control in diabetic hemodialysis patients.

Characteristics of De Novo Acute Myeloid Leukemia Patients in Palestine: Experience of An-Najah National University Hospital

Objective: To describe the characteristics of de novo acute myeloid leukemia (AML) in the Palestinian population. Study design and setting: A retrospective chart review study was conducted at An-Najah National University Hospital (NNUH) during the period of January, 2014 to December, 2016. Methodology: The medical records of AML patients treated at NNUH were reviewed. All patients at least 16 years of age diagnosed with de novo AML and started on induction chemotherapy were included. Descriptive statistics were employed to analyze the data. Results: Out of 88 patients diagnosed with AML during the study period, 64 had de novo AML and were included. Median age at diagnosis was 36 years, with a male to female ratio of 1.13:1. Two thirds of the cases were from the West Bank and the remainder were from Gaza. Major complaints at presentation were fatigue (64.1%), fever (46.9%), respiratory tract infections (39.1%) and bruising (28.1%). Hepatomegaly was present in 23.4% and splenomegaly in 34.4%. At presentation, the median white blood cells (WBC) count, hemoglobin (Hb) concentration and platelet count were 30. 5x109/L, 9.3g/ dL, and 39.5 x109/L, respectively. According to the French American British (FAB) classification, M4 was the most common subtype (32.8%) followed by M3 (21.9%). After a single cycle of induction chemotherapy complete remission (CR) was seen in 26 (41.9%) and non-remission (NR) in 17 (27.4%), while 19 patients (30.6%) died during the first admission for induction. Conclusion: The characteristics of de novo AML in Palestinian patients are comparable to published data elsewhere. M4 was the most common subtype. The outcome of the first cycle of induction chemotherapy was slightly inferior to the published data for M3 patients. Further studies are warranted to identify possible causes.

A hybrid approach for quantifying aortic valve stenosis using impedance cardiography and echocardiography.

BACKGROUND: Impedance cardiography (IC) is a noninvasive modality that utilizes changes in impedance across the thorax to assess hemodynamic parameters, including stroke volume (SV). This study compared aortic valve area (AVA) as assessed by a hybrid approach of transthoracic echocardiography (TTE) and impedance cardiography (IC) to AVA determined at cardiac catheterization using the Gorlin equation. METHODS: A total of 30 patients with moderate to severe aortic stenosis underwent AVA measurement using two different approaches: using the continuity equation (CE) in a hybrid method combining IC and TTE (AVA = stroke by volume impedance cardiography/trans-aortic-VTI) and using the Gorlin equation. Patient age ranged from 37 to 82 years (mean 48); there were 21 men and 9 women. Twenty-five patients were in sinus rhythm, and five had atrial fibrillation. RESULTS: There was no statistically significant difference for the mean AVA between the two methods (0.7 ± 0.24 cm(2) using the Gorlin equation versus 0.7 ± 0.23 cm(2) using the hybrid approach, p = 0.17; r = 0.76, p < 0.001). The mean difference was 0.004 cm(2), and the limits of agreement were -0.33 to 0.37. CONCLUSION: The hybrid method using impedance cardiography and TTE is a reasonable, clinically applicable approach to evaluate AVA and has significant correlation to invasive measurement using the Gorlin equation.
