Comparison Of Vascular Calcification And Mineral Bone Disease In Non-Dialysis (CKD4/5ND) Vs Dialysis Dependent (CKD5D) Patients.

BACKGROUND: Chronic kidney disease (CKD) has been a highly prevalent medical condition in all parts of the world affecting the haemostasis of the body in number of ways. Epidemiological data suggest that no region of the world has been spared from this condition and both developing and developed countries equally share the burden of this disease. Objective was to compare the vascular calcification and mineral bone disease in non-dialysis vs dialysis patients suffering from chronic kidney disease at a tertiary care hospital of Pakistan. It is a Comparative study, conducted at the Department of nephrology Pak Emirates Military Hospital Rawalpindi. Four months from November 2020 to February 2021. METHODS: A total of 310 cases were included in the study, which were diagnosed as chronic kidney disease in nephrology department by a consultant nephrologist on basis of National Kidney Foundation/Kidney Disease Outcome Quality Initiative (NKF/KDOQI) 2002. They were divided into two equal groups by block randomization. Group I had the patients who were not dependent on dialysis (CKD4/5ND) while group II had dialysis dependent patients. Abdominal aorta, mitral and tricuspid valves were assessed to look for vascular calcification. Calcium, phosphate and parathyroid hormone levels were done to assess the mineral bone profile. RESULTS: Out of 310 patients, 192 (61.9%) patients were males and 118 (38.1%) were females. Ninty-eight (31.6%) had evidence of vascular calcification while 212 (68.4%) did not have vascular calcification. 147 (47.4%) had hypocalcaemia, 167 (53.8%) had hyperphosphatemia while 98 (31.6%) patients had raised Parathyroid hormone levels. Regression analysis revealed that vascular calcification and abnormal mineral bone profile was significantly present more among patients who were dependent on dialysis (p-value<0.05). CONCLUSIONS: Bone mineral disease and vascular calcification were consistent findings among patients suffering from chronic kidney disease. Patients who were dependent on dialysis were more prone to develop these complications as compared to those who were not dependent on dialysis.

Association of Intestinal Microbial Dysbiosis With Chronic Obstructive Pulmonary Disease.

Normal gut flora plays various beneficial roles for the human body, including the protection against inflammatory states and mucosal viral infections. It also influences the immune system of the body. The metabolites produced by the gut bacteria control local and other systemic organs' immune functions like the lungs and brain, playing a role in their response to acute and chronic illnesses. Probiotics have shown beneficial effects on lung health. On the contrary, dysbiosis is associated with several diseases, including asthma, chronic bronchitis, emphysema, allergies, and other acute viral infections. By altering the diet of patients with respiratory diseases like patients with chronic obstructive pulmonary diseases (COPD), we may be able to mitigate their conditions. This literature review aims to discuss the mechanisms altering the gastrointestinal flora, the pathophysiology of gut and lung axis, the role of diet in gut microbe health, and the association of COPD with gut dysbiosis and peptic ulcer disease (PUD). We have extracted the data from PubMed and Google Scholar, consisting of review articles, case-control studies, and animal studies. The studies showed an association between gut microbes and different lung diseases. It is found that gut dysbiosis not only disrupts intestinal immunity but may also facilitate the development of COPD. Present studies also show an increased seroprevalence of Helicobacter pylori in patients with COPD. The strategies that can improve lung functions, especially in COPD patients, include prebiotics and probiotic supplementation to a diet more balanced than the current average American diet.

Association of Atrial Fibrillation With Patient Characteristics in Postoperative Coronary Artery Bypass Grafting Surgery.

Introduction Atrial fibrillation (AF) after coronary artery bypass grafting (CABG) is correlated with poor patient outcomes. The study evaluated the association of patients' clinical and sociodemographic characteristics with the incidence of atrial fibrillation, postoperatively.  Methodology A longitudinal study was performed in the cardiology department of a tertiary care unit, Sindh, Pakistan between October 2019 and November 2020. All patients who underwent CABG surgery irrespective of gender aged 30 to 75 years were included in the study. Patients with a history of atrial fibrillation or severe left ventricular dysfunction were excluded from the study. The incidence of atrial fibrillation was determined by observing an irregular pattern on electrocardiography (ECG) with no definite P-wave and irregular R-R interval. The patients were monitored for seven postoperative days. The final outcome was measured on the seventh postoperative day.  Results A total of 247 patients with a mean age of 63.43 ± 9.72 were enrolled in the study. Out of the 247 patients, 9.7% developed new-onset atrial fibrillation, postoperatively. Age above 65 years was associated with the occurrence of AF but it was not statistically significant (p>0.05). Similarly, patients who developed AF were more likely to have a left ventricle ejection fraction (LVEF) of less than 35% than those without AF (66.67% vs 43.95%; p=0.033).  Conclusion A high rate of AF was observed in the study. Older age and impaired ventricular function were significantly associated with atrial fibrillation. It is recommended that hospitals should devise guidelines and protocols for the prevention and management of atrial fibrillation in patients undergoing cardiothoracic surgeries in order to minimize patient mortality and improve patient outcomes.

Frequency of Electrolyte Imbalance in Patients Presenting With Acute Stroke.

Introduction Electrolyte disturbances are commonly reported in acute stroke in studies conducted in the western world. Presently, the data available about the prevalence of electrolyte disturbance in patients with stroke are not sufficient, especially from developing countries. The purpose of our study is to determine the frequency of occurrence of electrolyte imbalance in patients presenting with acute stroke in a tertiary care hospital. Methods This descriptive cross-sectional study was conducted in the department of internal medicine and neurology in a tertiary care hospital, Pakistan, from December 2019 to March 2021. A total of 300 patients, aged between 30 and 70 years, with either ischemic or hemorrhagic stroke, as diagnosed on contrast tomography (CT) scan of the head or magnetic resonance imaging (MRI) of the brain, were enrolled in the study. The biochemical analysis of the stroke patients was done. Results Out of the 300 participants, 139 (46.3%) participants were from the ischemic stroke group while 161 (53.7%) were from the hemorrhagic stroke group. The mean sodium level was significantly lower in the ischemic group as compared to the hemorrhagic group (129.41 ± 3.12 mEq/L vs. 134.42 ± 3.46 mEq/L; p-value: <0.0001). Potassium level was significantly higher in the hemorrhagic group compared to the ischemic group (6.27 ± 1.12 mmol vs. 4.31 ± 0.71 mmol; p-value: <0.0001). Conclusion Patients coming to emergency with stroke should be screened immediately for electrolyte imbalance. Early identification of rapid imbalances of serum electrolytes may aid in prompt medical intervention and resultant improved outcomes in stroke patients. It is crucial that electrolyte imbalances in these patients are closely monitored to avoid any complications.

Right Unilateral Versus Bilateral Electroconvulsive Therapy in Patients With Clinical Depression.

Introduction Electroconvulsive therapy (ECT) is a functional treatment for a significant mental illness that involves a momentary application of electrical stimulation to induce generalized seizures. The use of right unilateral (RUL) and bilateral (BL) ECT has been controversial. Thus, the study aimed at comparing the effectiveness of RUL ECT and BL ECT in treating depression. Methodology A longitudinal study was conducted between September 2016 and January 2021 at a tertiary care hospital in Sindh, Pakistan. All patients over the age of 18 with clinically diagnosed depression in the last month were included in the study. Baseline depression scores and post-treatment scores were determined using Hamilton Depression Rating Scale (HDRS). All patients were assigned to each treatment group. Group A was administered right unilateral electroconvulsive therapy, while group B was administered bilateral electroconvulsive therapy. Adverse effects were documented right after treatment, at four hours, and then one day after therapy. Depression severity was determined after each ECT session using the HDRS scale. Electroconvulsive therapy was discontinued when an HDRS score of 10 was achieved.  Results  The mean HDRS score at baseline in the bilateral ECT group was 24.99 ± 3.938, which lowered to 17.56 ± 2.65 by the 3rd session, 12.45 ± 3.76 by the 6th session, and to 11.86 ± 2.3 by the end of treatment (p<0.0001). Similarly, the right unilateral ECT was equally effective in improving the depressive symptoms (p<0.0001). There was no significant difference between the efficacy of bilateral and unilateral placements of electrodes in electroconvulsive therapy (p=0.116).

The Comparison Of Efficacy Between Losartan And Diltiazem As Antiproteinuric Agent In Non-Diabetic Renal Diseases.

BACKGROUND: Multiple options have been tried to counter the proteinuria secondary to renal diseases. Clinicians and researchers are trying to find the best option for this purpose. OBJECTIVE: To compare efficacy of Losartan and Diltiazem in management of proteinuria in nondiabetic renal diseases at a tertiary care hospital of Pakistan. It was a Quasi-experimental study, conducted at the Department of nephrology Pak Emirates Military Hospital Rawalpindi. Five months, November 2020 to March 2021. METHODS: A total of 122 patients of non-diabetic renal diseases with significant proteinuria were included in the study. They were randomly divided into two groups via lottery method. Group I received losartan while group II received Diltiazem in standard dose for three months. After three months they underwent 24 hours' urinary protein levels and divided into complete, partial and non-responders to treatment. Age, gender, duration of illness and type of antiproteinuric treatment was correlated with response to treatment among the study population. RESULTS: Out of 122 patients, 80 (65.6%) were males while 42 (34.4%) were females. Membranous nephropathy 20 (16.4%) was the commonest non-diabetic renal disease seen in our study participants. Thirty (24.5%) had complete remission after three months of treatment, 60 (49.2%) had partial response while 32 (26.3%) had no response to treatment. Chisquare test revealed that use of losartan had statistically significant relationship (p-value<0.001) with good response among the study participants. CONCLUSIONS: Membranous nephropathy leading to proteinuria was the commonest non-diabetic renal disease encountered in our setup. Around 2/3rd of our patients showed either complete or partial response to treatment and Losartan was superior to Diltiazem in achieving response in our study participants.

Hg(II) sensing, catalytic, antioxidant, antimicrobial, and anticancer potential of Garcinia mangostana and α-mangostin mediated silver nanoparticles.

This study reports synthesis of Garcinia mangostana fruit pericarp (unwanted waste material) and α-mangostin mediated silver nanoparticles (AgNPs). These AgNPs were efficiently produced using 1:10 (extract and salt) ratio under stirring and heating, which was confirmed by surface plasmon resonance (SPR) band in UV-Visible spectroscopic analysis, and size of 73-91 nm determined by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The synthesized AgNPs were used for Hg(II) detection in tap water, where the limits of detection and quantification were 2.6 µM and 8.9 µM, respectively. Furthermore, the subject AgNPs showed promising catalytic activity in the reduction of dyes and food colours including Congo red (CR), methylene blue (MB), malachite green (MG), methyl orange (MO), para-nitrophenol (PNP), rhodamine B (RdB), zarda yellow (ZY), deep green (DG), and bright red (BR). The synthesized AgNPs were also evaluated for their antioxidant, antimicrobial, and anticancer properties, where α-mangostin and its nanoparticles (Mang-AgNPs) exhibited promising IC50 values of 14.1 and 13.5 µg/mL, respectively against DU-145 cell line validated by in silico molecular docking study. This study is the first report highlighting the application of AgNPs of G. mangostana fruit pericarp extracts, and α-mangostin in Hg(II) detection, dyes degradation, and anticancer potential against DU-145. Finding of this study suggested the suitability of AgNPs as promising solid biosensor in Hg(II) metal detection, dyes reduction, and target in anticancer drug development.

Characterization of natural gums via elemental and chemometric analyses, synthesis of silver nanoparticles, and biological and catalytic applications.

Gums; composed of polysaccharides, carbohydrates, proteins, and minerals, are high molecular weight hydrophilic compounds with several biological applications. This study describes the nutritional and toxic elements content, chemical composition, synthesis of silver nanoparticles (G-AgNPs), and pharmacological and catalytic properties of Prunus armeniaca (apricot), Prunus domestica (plums), Prunus persica (peaches), Acacia modesta (phulai), Acacia arabica (kikar), and Salmalia malabarica (silk cotton tree) gums. The elemental contents were analyzed by inductively coupled plasma-optical emission spectroscopy (ICP-OES) and ICP-mass spectrometry (ICP-MS). NMR spectroscopy was used for the identification of class of compounds in the mixture, their functional groups were determined through FTIR techniques, and plasmon resonance and size of G-AgNPs through UV-Vis spectroscopic technique and transmission electron microscopy (TEM). From the results, nutritional elements were present at appreciable concentrations, whereas toxic elements showed content below the maximum permissible ranges. Using the elemental data, linear discriminant and principal component analyses classified the gums to 99.9% variability index. Furthermore, G-AgNPs exhibited significant antioxidant, antibacterial, and redox catalytic potential. Hence, the subject G-AgNPs could have promising nutritional, therapeutic and environmental remediation applications.

Prevalence and Predictors of Blood Pressure Screening in Karachi: A Cross-sectional Study.

Background There is a lack of data about hypertension screening in low- to middle-income countries. The primary objective of this study was to determine the prevalence and predictors of blood pressure (BP) screening in Karachi, Pakistan. The secondary objective was to identify ways to improve effective BP screening practices among the population at risk. Methods This cross-sectional study was conducted from November 2016 to May 2017. The sample population consisted of 2039 residents of Karachi who were older than 18 years. A well-composed questionnaire was pilot tested and then used to assess their socio-demographic characteristics, personal attitude towards a healthy lifestyle, dietary habits, and BP screening practices. We used a chi-squared test as the primary statistical test. Results Of 2039 people, 1627 had their BP checked at least once in their lifetime. Approximately, half of the participants had their BP checked on a yearly basis. Women had a higher rate (83.6%, n = 989) of getting their BP checked than men (74.5%, n = 636). A significant relationship was observed between BP screening and lifestyle practices such as physical activity (p = 0.00), hours of sleep (p = 0.01), water intake (p = 0.01), and dining out (p = 0.03). Conclusion Current BP screening practices are inadequate amongst the urban population of Karachi. There is an urgent need for federal implementation of BP screening as well as awareness programs across the nation.

Successful management of a spontaneous viable monochorionic diamniotic twin pregnancy on cesarean scar with systemic methotrexate: A case report.

RATIONALE: Cesarean scar twin pregnancy is exceedingly rare and it remains to be a life-threatening condition even in the early weeks of gestation. Because of its rare occurrence, there is no consensus on the treatment modality of cesarean ectopic pregnancy. PATIENT CONCERNS: A 41-year-old, woman, gravida 7, para 6, with a history of low transverse cesarean section 2 years back presented with an estimated 6 weeks gestational age and viable spontaneous twin, monochorionic diamniotic gestation. The patient presented to the Emergency Department with complaints of vaginal bleeding and mild lower abdominal pain for 5 days. DIAGNOSES: An ultrasound examination was performed demonstrating a single intrauterine gestational sac with 2 viable embryos (monochorionic diamniotic) implanted in the lower uterine segment at the level of the prior cesarean section scar. A diagnosis of viable cesarean scar twin pregnancy was made. INTERVENTIONS: A 2 doses of 50 mg/m methotrexate (MTX) was given intramuscularly. The response to the treatment was monitored by serial beta-human chorionic gonadotropin (ß-hCG) and ultrasound. OUTCOMES: Patient was followed up with ß-hCG weekly levels which became 0 after 68 days of treatment. During the follow-up, the patient was asymptomatic, no side effects of MTX were noticed. LESSONS: We reported a rare case of viable monochorionic diamniotic twin pregnancy on a cesarean scar that was successfully treated with systemic MTX without any additional therapy. Additionally, the decline of ß-hCG in twin ectopic cesarean scar pregnancy appears to be similar to a singleton ectopic pregnancy.

Saline infusion sonohysterography versus hysteroscopy for uterine cavity evaluation.

BACKGROUND AND OBJECTIVES: The most frequent procedures performed on women with abnormal uterine bleeding are 2D and 3D ultrasound. The most common accepted approach for the management of abnormal uterine bleeding is 2D TV scan followed by therapeutic hysteroscopy. The purpose of this prospective study was to assess whether 3D saline infusion sonohysterography (3D SIS) could replace diagnostic hysteroscopy (DH) for the diagnosis of endometrial pathology, in patients with abnormal uterine bleeding. DESIGN AND SETTING: A prospective study in the ultrasound department of the Women's Specialized Hospital, King Fahad Medical City, Riyadh, Saudi Arabia from January 2008 to February 2010. PATIENTS AND METHODS: 0One hundred and one patients with abnormal uterine bleeding, suspected to have endometrial abnormality by 2D and 3D transvaginal scan, were prospectively studied. Of these, 55 patients had undergone both 3D SIS and DH, followed by verification of results with histopathology. RESULTS: Upon comparison of 3D SIS and DH individually with histopathology, specificity and sensitivity for 3D SIS were 67% and 100%, respectively, and for hysteroscopy 67% and 98%, respectively. In addition, the positive predictive value and negative predictive value were 98% and 100%, respectively, for 3D SIS, while for DH they were 98% and 67%, respectively. CONCLUSION: 3D SIS is a safe alternative to hysteroscopy. However, larger randomized controlled trials should be conducted to ascertain the validity and reliability of this advantageous, less-invasive procedure, for women with abnormal uterine bleeding, who require evaluation of the endometrial cavity.
