ACE gene polymorphism and susceptibility to hypertension in a Jordanian adult population.

Hypertension is one of the most common and complicated disorders associated with genetic and environmental risk factors. The angiotensin-converting enzyme (ACE) is important in the renin-angiotensin-system pathway. The gene expression of ACE has been investigated as a possible hypertension marker. This study investigates the association between polymorphisms within the ACE1 and ACE2 genes and hypertension susceptibility in a Jordanian population. The study comprised a total of 200 hypertensive patients and 180 healthy controls. A polymerase chain reaction (PCR) was performed to genotype the candidate polymorphism (rs4646994) of the ACE1gene. The Luminex DNA array technique was used for genotyping SNPs (rs4359, rs4344, rs4341, rs4343, and rs2106809) of the ACE1 and ACE2 genes. Our findings suggest no association between SNPs and hypertension regarding allelic and genotypic frequencies. However, rs4359 was significantly associated with diet (pP = 0.049), know HTN (P = 0.042), and number of years DM (P = 0.003). rs4341 was associated with diet (P = 0.032), peripheral vascular disease (P = 0.005), and chronic kidney disease (p = 0.049). While rs4343 was associated with diet (P = 0.031), diabetes mellitus (P = 0.032), and other medication (P = 0.025). Furthermore, the haplotypes of four SNPs of the ACE1 gene showed no significant association with HTN patients and healthy controls. Our findings indicate no association between the polymorphisms in the ACE gene and the risk of hypertension development in the Jordanian adult population.

Prevalence of Obstructive Sleep Apnea Among Atrial Fibrillation Patients: A Cross-Sectional Study from Jordan.

Background: Obstructive Sleep Apnea (OSA) is a common respiratory disorder that causes intermittent upper airway collapse during sleep and can lead to various acute cardiovascular complications. Atrial Fibrillation (AF) is the most common sustained cardiac arrhythmia and is associated with an increased risk of cardiovascular hospitalization and all-cause mortality. Our study aimed to investigate the prevalence of individuals with AF and those considered at high risk for OSA. Methods: A cross-sectional study was conducted with a population comprising patients who had visited KAUH cardiology clinics between 2017-2019; subjects were categorized into AF patients and general cardiology patients. Patients were surveyed for OSA using the Berlin Questionnaire to assess the degree of OSA symptoms and to classify patients into high- or low-risk groups based on their responses. Results: Of the 656 patients, 545 met our inclusion criteria, of whom 192 were diagnosed with AF. Comparable demographic characteristics were observed between the AF and non-AF groups, barring higher rates of obesity (p=0.001) and smoking (p=0.042) in the AF group. The prevalence of high-risk OSA was significantly higher in AF patients (68.2%) compared to non-AF patients (29.4%), with an adjusted odds ratio of 2.473 times (95% CI: 1.434 -4.266, p=0.001) greater for AF. The age, gender, and BMI categories did not differ significantly between the two groups. Binary logistic regression revealed significant associations between OSA and risk factors such as asthma (OR=4.408, 95% CI: 2.634-7.376, p=0.001). Conclusion: These results serve to display a statistically significant increase in high-risk OSA in existing AF patients, irrespective of the presence of conventional OSA risk factors; this could imply a more immediate and direct relationship between both diseases and calls to include routine screening for OSA in patients diagnosed, newly or otherwise, with AF.

The presence or absence of midsagittal tissue bridges and walking: a retrospective cohort study in spinal cord injury.

STUDY DESIGN: Cohort study. Retrospective analysis of T2-weighted magnetic resonance images (MRIs) and clinical documentation. OBJECTIVES: To evaluate the relationship between the presence/absence and widths of midsagittal tissue bridges and walking ability among veterans with cervical, predominantly chronic SCI. SETTING: University research and hospital setting. METHODS: T2-weighted midsagittal MRIs of 22 United States veterans with cervical spinal cord injuries were examined. The presence/absence of midsagittal tissue bridges were determined, and the widths of present ventral and dorsal tissue bridges were measured. Midsagittal tissue bridge characteristics were related to each participant's ability to walk based off examination of clinical documentation. RESULTS: Fourteen of the analyzed participant images revealed the presence of midsagittal tissue bridges. Ten of those individuals (71%) possessed overground walking ability. The 8 individuals with no apparent tissue bridges were all unable to walk. There was a significant correlation between walking and widths of ventral midsagittal tissue bridges (r = 0.69, 95%CI: 0.52, 0.92, p < 0.001), as well as dorsal midsagittal tissue bridges (r = 0.44, 95%CI: 0.15, 0.73, p = 0.039). CONCLUSION: The evaluation of midsagittal tissue bridges may be useful in various rehabilitation settings to help inform patients' plan of care, allocation of neuromodulatory resources, and appropriate stratification into research cohorts.

Reported Adverse Effects and Attitudes among Arab Populations Following COVID-19 Vaccination: A Large-Scale Multinational Study Implementing Machine Learning Tools in Predicting Post-Vaccination Adverse Effects Based on Predisposing Factors.

Background: The unprecedented global spread of coronavirus disease 2019 (COVID-19) has imposed huge challenges on the healthcare facilities, and impacted every aspect of life. This has led to the development of several vaccines against COVID-19 within one year. This study aimed to assess the attitudes and the side effects among Arab communities after receiving a COVID-19 vaccine and use of machine learning (ML) tools to predict post-vaccination side effects based on predisposing factors. Methods: An online-based multinational survey was carried out via social media platforms from 14 June to 31 August 2021, targeting individuals who received at least one dose of a COVID-19 vaccine from 22 Arab countries. Descriptive statistics, correlation, and chi-square tests were used to analyze the data. Moreover, extensive ML tools were utilized to predict 30 post vaccination adverse effects and their severity based on 15 predisposing factors. The importance of distinct predisposing factors in predicting particular side effects was determined using global feature importance employing gradient boost as AutoML. Results: A total of 10,064 participants from 19 Arab countries were included in this study. Around 56% were female and 59% were aged from 20 to 39 years old. A high rate of vaccine hesitancy (51%) was reported among participants. Almost 88% of the participants were vaccinated with one of three COVID-19 vaccines, including Pfizer-BioNTech (52.8%), AstraZeneca (20.7%), and Sinopharm (14.2%). About 72% of participants experienced post-vaccination side effects. This study reports statistically significant associations (p < 0.01) between various predisposing factors and post-vaccinations side effects. In terms of predicting post-vaccination side effects, gradient boost, random forest, and XGBoost outperformed other ML methods. The most important predisposing factors for predicting certain side effects (i.e., tiredness, fever, headache, injection site pain and swelling, myalgia, and sleepiness and laziness) were revealed to be the number of doses, gender, type of vaccine, age, and hesitancy to receive a COVID-19 vaccine. Conclusions: The reported side effects following COVID-19 vaccination among Arab populations are usually non-life-threatening; flu-like symptoms and injection site pain. Certain predisposing factors have greater weight and importance as input data in predicting post-vaccination side effects. Based on the most significant input data, ML can also be used to predict these side effects; people with certain predicted side effects may require additional medical attention, or possibly hospitalization.

Observational evidence on the coastal upwelling along the northwest coast of India during summer monsoon.

The lesser known coastal upwelling in the North Eastern Arabian Sea (NEAS) during summer monsoon, its associated dynamics and forcing mechanisms is elucidated for the first time using basin scale monthly time-series in-situ and satellite data. The presence of cool upwelled waters along northwest coast of India from July to early October with an associated increase in productivity was evident in both data. The low level Findlater jet blows towards west coast of India with high wind magnitude (10-12 m/s) during summer monsoon generates strong Ekman transport (1416 kg/m/s) at offshore and Ekman pumping velocity (1.349 m/s) at coastal region initiates upwelling. It was identified that the currents and remote forcing also regulate upwelling along the region. Although upwelling seems to exist along the northwest coast, it was weaker (25.5 °C) compared to the southwest coast where the SST dropped to 24 °C. The upwelling was observed in the south during June as a surface process, while it was observed along the northwest coast of India by the end of August. Even though the onset of upwelling in the NEAS and South Eastern Arabian Sea (SEAS) had a lag of two months, the recession of upwelling happened during late and early September respectively. The cause for the lag in the onset and cessation of upwelling between SEAS and NEAS is attributed to the propagation of Kelvin waves and southwest monsoon winds. The study also reveals that temperature and chlorophyll profiles show bi-modal peaks of high and low associated with winter cooling (winter) and upwelling (summer).

Pseudomonas-Contaminated Pool Triggering an Episode of Idiopathic Palmoplantar Hidradenitis.

Idiopathic palmoplantar hidradenitis (IPPH) is a disorder that mainly affects the palms and soles of children. Although many cases have been reported to occur after recreational swimming activities, whether IPPH is caused by intense physical activity or by Pseudomonas infection has yet to be proven. We report a case of a 3-year-old girl who presented with IPPH after swimming in a pool with evidence of P. aeruginosa contamination, further solidifying the association between Pseudomonas and IPPH.

The impact of COVID-19 on surgical practice in Jordan during the second outbreak: A survey.

BACKGROUND: COVID-19 is an acute respiratory pandemic with no available effective antiviral treatment or widely available effective vaccine. Surgical practice has faced widespread problems due to the pandemic including viral transmission risk and cross-infection, staffing problems, prioritizations of surgical procedures, and lack of beds due to occupancy of hospitals and ICU beds with COVID-19 patients. METHODS: A survey was conducted between October 31 to November 4, 2020, through google forms. The questionnaire involved 16 questions sent to consultants and specialists of all general and special surgical specialties and subspecialties in Jordan. RESULTS: We have got responses from surgeons of all public and private sectors in Jordan. There was a pronounced decline in the number of elective and emergency procedures performed during October 2020 due to COVID-19 pandemic related reasons. CONCLUSIONS: The impact of COVID-19 on the surgical practice in Jordan during October 2020 was moderate to prominent. Measures that could be made to alleviate this impact include the assignment of certain hospitals for covid-19 patients as a step before the establishment of field hospitals and the cooperation between the private and the public health sectors.

Impact of PCSK9, WDR12, CDKN2A, and CXCL12 Polymorphisms in Jordanian Cardiovascular Patients on Warfarin Responsiveness and Sensitivity.

BACKGROUND: The main objective of this study is sought to determine the impacts of PCSK9, WDR12, CDKN2A, and CXCL12 polymorphisms on warfarin sensitivity and responsiveness in Jordanian cardiovascular patients during the initiation and stabilization phases of therapy. METHODS: This study took place at the anticoagulation clinic at Queen Alia Heart Institute (QAHI) in Jordan. DNA samples were collected from 212 cardiovascular patients and 213 healthy controls. Genomic SNPs genotyping was conducted using the MassARRAY System at the Australian Genome Research Facility. RESULTS: This study assessed 10 polymorphisms (rs11206510 within the PCSK9 gene, rs6725887 and rs7582720 within the WDR12 gene, rs4977574, rs10757278, and rs1333049 within the CDKN2A gene, rs2862116, rs7906426, rs1746048, and rs268322 within the CXCL12 gene) in 212 Jordanian cardiovascular patients. Carriers of CDKN2A rs1333049, rs10757278, and PCSK9 rs11206510 polymorphisms had an increased risk of resistance during the initiation phase of warfarin therapy compared to those who do not carry it, or those who are carrying one polymorphism only (P < 0.05), while carriers of CXCL12 rs7906426 polymorphism had similar increased risk but during the stabilization phase of warfarin therapy (P < 0.05). CONCLUSION: Carriers of CXCL12 rs2862116 polymorphism had an increased risk to be warfarin extensive responders compared to those with no or only one polymorphism (P = 0.01). However, the presence of PCSK9 rs11206510 polymorphism affects the warfarin maintenance doses (P ˃ 0.0001).

Physiological and Histological Changes in Pancreatic Gland Associated with Ageing in Local Rabbits in Iraq.

The pancreas is a pear-shaped flat organ resembling the letter L, and yellowish to pink in color. This organ is of medical significance since it is associated with two life-threatening diseases including diabetes mellitus and pancreatic cancer. This study was conducted on male rabbits which were assigned into 3 age groups (6-month-old, 1-year-old, and 3-year-old rabbits). Physiological and histological changes of the pancreas were studied in the adopted age groups. The physiological aspect and the histological structure of the pancreas were also studied by the analysis of the level of pancreatic gland hormones and hormonal changes. Based on the results, there were significant differences in the concentration of pancreatic gland hormones. Insulin level in the second study group was more than that in the first and third groups, while the highest concentration of blood sugar (glucose) was observed in the third group, compared to the first and second. Although the basic structure of the pancreas was similar in all samples, changes were observed in the tissue structure of the pancreas throughout the process of aging. By the increase of age (from 1 to 3 years old), Langerhans islets increased in size, contained alpha and beta cells that were surrounded by a loose connective tissue in the third stage. Moreover, no significant difference was observed in the diameters of cells that produced enzymes at all stages of life. Physiological and histological changes indicated that age plays a role in the function and structure of the pancreas gland during different stages of life. In addition, this study indicated that the hormonal variability of the pancreas is closely related to the histological composition of gland components. Therefore, further studies on the role of factors, such as gender, different breeds, or environmental conditions seem to be necessary and may provide more information on factors that may affect the effectiveness and activity of the pancreas gland.

The Knowledge and Perception of Antiplatelet and Anticoagulant agents among Dentists in Northern Jordan.

OBJECTIVES: The aim of this study was to describe the attitude and perception toward antiplatelet/anticoagulant agents in patients with cardiovascular diseases among dentists in the northern district of Jordan and to compare the current practice of Jordanian dentists and the recently published guidelines regarding the management of patients taking antiplatelet/anticoagulant drugs before dental procedures. MATERIALS AND METHODS: This is a cross-sectional study conducted on dentists and dental interns working at the dental clinics in northern Jordan, including dental clinics at Jordan University of Science and Technology (JUST) and the private sector. The total sample size comprised of 128 subjects (78 dentists from JUST and 50 private practitioners). The participants were interviewed using a preformed questionnaire to assess their knowledge and perceptions regarding the antiplatelets and the anticoagulant agents. RESULTS: Approximately 61.5% of participants from JUST university and 20.0% of those in the private sector were aware of the use of clopidogrel (P < 0.0001). Although the overall awareness regarding other antiplatelets such as prasugrel was very low (8.6%), dentists from JUST (12.8%) showed a significantly higher level of awareness compared to the private practitioners (2.0%) (P = 0.049). More than 70% of the participants from JUST and only 46.0% of the private practitioners were aware of the consequences of interrupting treatment with clopidogrel in patients with coronary stents (P = 0.002). Almost both the participants from JUST (25.78%) and the private sector (24.22%) are consulting the cardiologists with similar frequencies before interrupting the treatment with the antiplatelet/anticoagulant agents. Participants who have clinical PhD qualifications are more aware of the recent clinical guidelines and the newest agents compared to others. CONCLUSIONS: The awareness regarding the newest antiplatelet/anticoagulant agents is poor among the dentists in northern Jordan. However, the majority (62.3%) of them realize the consequences of interrupting such treatments in patients with coronary stents. Unfortunately, only a quarter of the dentists are consulting the cardiologists before interrupting the treatment with the antiplatelet agents. Proper education, courses, and workshops should be performed to the dentists to improve their knowledge about this critical issue.

A 44 years-old male patient surviving total occlusion of the left main coronary artery (STEMI) accompanied with cardiogenic shock.

INTRODUCTION: Thrombus occlusion of the left main coronary artery (LMCA) is a poorly prognostic condition that is commonly associated with mortality especially when complicated with cardiogenic shock. PRESENTATION OF CASE: In this report, we presented a case for 44 years-old male patient who is not known to have ischemic heart disease. He was transferred from a peripheral hospital for emergency percutaneous coronary intervention (PCI) after presenting with anterior ST-elevation myocardial infarction (STEMI) complicated with cardiogenic shock. DISCUSSION: The PCI revealed complete occlusion of the LMCA with a thrombus which was stented and the patient regain his cardiovascular stability. The patient survived this complete occlusion that was complicated with cardiogenic shock giving the quick intervention with the PCI and the use of the circulatory support devices. CONCLUSION: The PCI procedure with the intra-aortic balloon pump should be available and offered early for patients with STEMI complicated with cardiogenic shock. This could be very critical in increasing the survival rates for those patients.

Description on variability of shelf-edge hydrography and current structure of the South Eastern Arabian Sea during summer and winter monsoons.

The paper describes the hydrography and vertical current structure along the shelf edge of South East Arabian Sea (SEAS) during summer and winter monsoons based on current profiles from moving Acoustic Doppler Current Profiler (ADCP). During summer monsoon, SEAS was characterized by upwelling with low saline water at the surface along the southern sector (8° N to 11° N). During winter, thermal structure was vertically homogeneous in the upper 80 m, and intrusion of low saline Bay of Bengal waters were found up to 14° N. In the southern sector, turbidity was more than the northern sector during winter and summer seasons. ADCP-derived current profiles during summer along 200-m isobath show dominant northward flow in the south, and southeasterly in the north as part of the West India Coastal Current (WICC). A comparison between ADCP current profiles and Ekman currents during summer indicates dominance of remote forcing (coastal Kelvin waves) over the local wind forcing in the 8-9° N sector whereas a combined influence of both remote forcing and wind in the 9-15° N sector. During winter, the direction of surface current reversed and was poleward generally except at the southern sector (7-8° N) where the flow was southwestward. Sector-wise comparison of ADCP and Ekman current showed less influence of wind on current fields throughout the sector except at south; wind has a major role in the current generation, whereas along the 8-15° N sector, the remote forcing dominates over the wind.

Screening for obstructive sleep apnea among patients undergoing coronary catheterization in Jordan.

Aims: This study aimed to utilize a validated sleep questionnaire as a screening tool for symptoms and risk of obstructive sleep apnea in patients undergoing coronary catheterization in Jordan. Materials and methods: A cross-sectional design was used to screen adult patients undergoing coronary catheterization for obstructive sleep apnea (OSA). The Berlin sleep questionnaire was used to record nocturnal and daytime symptoms of OSA and to stratify patients into "low-risk" or "high-risk" for OSA. Coronary artery disease was defined as ≥50% intraluminal stenosis in at least one coronary vessel. Results: A total of 398 patients were studied, mean age was 58.7 years (SD=10.70), ranging from 21-92 years, and 68.6% were males. Based on the Berlin sleep questionnaire's definition, 176 patients (44.2%) were at high-risk for obstructive sleep apnea. Snoring was reported by 61%; loud in 42.1%, and frequent in 62%. Daytime sleepiness was reported by 36%, and 18.9% had fallen asleep while driving. Witnessed apnea during sleep was less reported (7.8%). Prevalence of symptoms and risk of OSA were not different between patients with and without coronary artery disease, P>0.05. In addition, logistic regression indicated that there was no significant association between risk of OSA and coronary artery disease, adjusted (odds ratio=0.93, 95% Confidence Interval=0.60-1.44, P=0.752). Conclusions: Symptoms and risk of obstructive sleep apnea were common among adult Jordanians undergoing coronary catheterization. There was no association between risk of obstructive sleep apnea and coronary artery disease. Larger studies are needed to assess the role of screening for obstructive sleep apnea in this patient population.

Prevalence of undiagnosed COPD in male patients with coronary artery disease: a cross-sectional study in Jordan.

Purpose: COPD and coronary artery disease (CAD) are common chronic diseases with shared risk factors. COPD continues to be largely underdiagnosed and undertreated. We aimed to describe the prevalence and predictors of undiagnosed COPD in Jordanian men with CAD. Patients and methods: In a cross-sectional study conducted at a referral center in Jordan, male patients who underwent coronary angiography for suspected CAD and reported ≥10 pack-year of cigarette smoking were recruited. Pre- and post-bronchodilator spirometry was undertaken for all participants, and COPD was defined as post-bronchodilator FEV1/FVC <70%. The finding of ≥50% coronary luminal narrowing confirmed the presence of CAD. Results: Spirometry was undertaken for 376 men with mean age of 56.02±10.55 years, and 72.6% were active cigarettes smokers with a mean pack-year of 55.89±34.25. A CAD diagnosis was confirmed in 300 (79.8%) men. Spirometric criteria for COPD were met in 76 (15.7%) patients, of whom 91.5% were not previously diagnosed. COPD-related symptoms were common: chronic cough (44.4%), dyspnea (66.2%), and wheezes (27.9%). COPD was more common in patients with (18.0%) compared to patients without (6.6%) CAD (P=0.014). Multivariate logistic regression showed that the risk of COPD was higher in patients with CAD (OR 3.16, 95% CI, 1.10-9.09, P=0.033) and in those with chronic bronchitis (OR 13.07, 95% CI, 6.69-25.52, P<0.001). Conclusion: There was a high prevalence of COPD among male patients with CAD and most were underdiagnosed despite having respiratory symptoms. Male smokers with CAD and respiratory symptoms should be evaluated for airflow limitation and the presence of COPD.

Developing a Breast Cancer Screening Program in Nigeria: Evaluating Current Practices, Perceptions, and Possible Barriers.

PURPOSE: In low- and middle-income countries like Nigeria, women present with advanced breast cancer at an earlier age. Given the limited resources, development of screening programs that parallel resource capabilities of low- and middle-income countries is imperative. The objective of this study was to evaluate the perceptions, practices, and barriers regarding clinical breast examination (CBE) screening in a low-income community in Nigeria. MATERIALS AND METHODS: A cross-sectional survey of women age 40 years or older in Ife, Nigeria, using multistaged sampling was performed. Information on sociodemographics, knowledge of breast cancer, screening practices, and willingness to participate in CBE screening was obtained using an interviewer-administered questionnaire. RESULTS: A total of 1,169 women whose ages ranged from 40 to 86 years (mean age, 47.7 years; standard deviation, 8.79 years) were interviewed. The majority of women (94%) knew about breast cancer, whereas 27.5% knew someone who had had breast cancer, the majority of whom (64.5%) had died of the disease. Of the 36% of women who had breast screening recommended to them, only 19.7% had an actual CBE. Of these, only 6% had it in the last year. The majority of women (65.4%) were willing to have regular CBEs and did not care about the sex of the examiner in most instances. Lack of perceived need was the reason cited by women unwilling to participate. CONCLUSION: The majority of women were aware of breast cancer and knew it as a fatal disease. With the relatively encouraging number of those willing to be examined, a carefully designed CBE program coupled with advocacy to correct uneducated beliefs seems promising.

Impact of introduction of laparoscopic surgery on management of unresolved intra-abdominal malignancies in a West African hospital.

BACKGROUND: Intra-abdominal malignancies often pose diagnostic problems to surgeons in resource-challenged centers such as ours due to limitations in modern imaging and other facilities. This prompted the adoption of laparoscopy in our hospital as an adjunctive tool in diagnosing these conditions. METHOD: Pre- and per-operative data of consecutive cases of clinically unresolved advanced intra-abdominal tumors subjected to laparoscopy from January 2009 through June 2013 were reviewed. Anatomic diagnosis and tissue biopsies were carried out during the procedures. RESULTS: Of the 152 patients seen with intra-abdominal tumors, 74 (48.7 %) had advanced conditions that could not be resolved clinically. Of these, 33 (44.6 %) were able to afford and had computed tomography (CT), scan while the remaining (N = 41; 55.4 %) less endowed only had an ultrasound scan. This cohort underwent laparoscopic evaluation, and biopsies confirmed the following: 27 (36.5 %) metastatic adenocarcinomas, 12 (16.2 %) primary hepatic malignancies, 11 (14.9 %) cases each of lymphomas and colonic adenocarcinomas, 4 (5.4 %) gastrointestinal stromal tumors, 3 (4.1 %) pancreatic carcinomas, 2 (2.7 %) cases each of carcinoid tumors and abdominal tuberculosis, and one case each of schistosomiasis and HIV-related Kaposi's sarcoma. Additionally, 26 (35.1 %) had ascites, while 29 (39.1 %) had peritoneal surface malignancies. With local adaptations and improvisations, laparoscopy was cheaper than an abdominal CT scan in our setting, with the additional benefit of obtaining tissue diagnosis to institute treatment. CONCLUSION: Although laparoscopy is commonly used for staging intra-abdominal tumors, we found it useful in complementing clinical diagnosis and attaining histopathological confirmation in a setting where access to and funding of modern imaging is limited.

Burden of prostate cancer in southwestern Nigeria.

OBJECTIVES: To determine the pattern of presentation, prevalent age, hospital incidence, and outcome of management of prostate cancer in our environment. METHOD: Patients with histopathology evidence of prostate cancer managed between January 1991 and December 2007 were studied. Information entered into a pro-forma sheet and analyzed included the age of patients, clinical features, investigations, histopathology diagnosis, outcome of management, and duration of follow-up. RESULTS: During the period, 189 patients aged 46-99 years (mean, 68.0; 9.8 SD) confirmed and managed for prostate cancer were studied. The average hospital incidence (2002-2004) was 182.5 per 10(5) male admissions with 15.1-month mean duration of symptoms. Most 178 (94.2%) patients presented with advanced diseases, with 1 or multiple complications in 172 (91.0%), obstructive lower urinary tract symptoms 156 (82.5%), distant metastasis 97 (51.3%), lower back pain 95 (50.3%), weight loss 95 (50.3%), hematuria 86 (45.5%), anemia 77 (40.7%), renal failure 74 (39.2%), and inability to walk 42 (22.2%). Eighty-nine (47.0%) patients were farmers, 111 (58.7%) indulged in alcohol, and 46 (24.3%) smoked cigarettes. Mean prostate-specific antigen results available in 53 patients was 106.0 ng/mL (187.2SD) and digital rectal examination was valuable in diagnosis. Adenocarcinoma (186 [98.4%]) was the main histopathology type and most patients 136 (71.9%) had bilateral orchidectomy with or without antiandrogens. Mean duration of follow-up was 83.7 weeks. CONCLUSIONS: The burden of prostate cancer in our developing community is worrisome. It is prevalent between 46 and 99 years in our community. Presentation is late, often with urinary retention and other complications. In our setting, treatment is still essentially palliative with orchidectomy, which we found to be beneficial, acceptable, and the most affordable to our patients.

A novel endometriosis inducing factor in women with endometriosis.

AIM: To confirm the hypothesis of the presence of a possible endometriosis inducing factor(s) (EIF) in the blood of women with endometriosis. PATIENTS AND METHODS: Forty infertile women were studied. The study group compromised of fifteen women of each three different degrees of endometriosis and fifteen women without endometriosis as a control group. Stem cells are characterized by being spindle shaped and proliferate in appropriate culture indefinitely. The women sera were co-cultured with mesenchymal stem cells (MSCs) which were followed up weekly to look for morphological changes and to detect Annexin 1 marker and ß-actin gene by reverse transcriptase polymerase chain reaction. RESULTS: MSCs cultured with sera of cases with, mild, moderate and severe endometriosis, showed morphological changes to be columnar and cuboidal shaped cells -resembling endometrial cells and glands- by the 4th week in 60%, 60% & 100% respectively. These cells were detected from as early as the first week in women with moderate and severe types (20% for each group). The percentage of the change into endometrial like cells increased among the three groups where it was 30±25.8%, 45±29.9% and 75±37.9% respectively. Moreover, increasing number of endometrial like cells are detected weekly, the more severe the disease is. None of the cultures of serum of the control group had made such changes all over the study. Furthermore, with more differentiation there was a considerable decrease in number of stem cells. These differentiated cells expressed the Annexin-1 marker. CONCLUSION: It was evident that serum of women with endometriosis posses a factor(s) that enables the MSCs to be transformed into endometrial like cells and glands in vitro. This finding supports a new theory for the etiology of endometriosis. This observation may have a tremendous effect on the therapeutic implications of this debilitating condition.

Prevalence and chemotherapy of babesiosis among Lohi sheep in the Livestock Experiment Station, Qadirabad, Pakistan, and environs

A total of 310 blood smears were collected from sheep of the Livestock Experiment Station, Qadirabad, Sahiwal district, Pakistan, and surrounding areas. The samples were examined microscopically and 30 (9.67 percent) were positive for babesiosis. The animals were divided into two groups (A and B) for chemotherapy. Group A sheep were treated with diminazene diaceturate while group B animals received imidocarb dipropionate. Drug efficacy was determined by negative blood smear examination. Diminazene diaceturate effectiveness against babesiosis was 80 percent while that of imidocarb dipropionate was 100 percent. Hematological studies revealed a significant decrease in hemoglobin concentrations and hematocrit values for Babesia-positive animals compared to healthy controls.(AU)
