Sclerostin and TNF-related weak inducer of apoptosis: can they be important in the patients with glomerulonephritis?

SUMMARY OBJECTIVE: Sclerostin is a protein produced by osteocytes, kidneys, and vascular cells and has many effects on kidney and vascular structures. Soluble TNF-related weak inducer of apoptosis is a proinflammatory cytokine that may cause glomerular and tubular injury and increase sclerostin expression. This study aimed to investigate serum sclerostin and soluble TNF-related weak inducer of apoptosis levels in patients with glomerulonephritis and the effects they may be associated with. METHODS: This cross-sectional study included 93 patients, 63 of whom were glomerulonephritis and 30 were healthy controls. Serum sclerostin, soluble TNF-related weak inducer of apoptosis, and 24-h urinary protein excretion were measured, and pulse wave velocity was calculated for arterial stiffness. RESULTS: Serum sclerostin and soluble TNF-related weak inducer of apoptosis were higher in glomerulonephritis patients than in the control group, and serum sclerostin and soluble TNF-related weak inducer of apoptosis levels were correlated with both proteinuria and pulse wave velocity. In addition, in the regression analysis, serum sclerostin and soluble TNF-related weak inducer of apoptosis levels were found to be independent predictors of proteinuria in patients with glomerulonephritis. CONCLUSION: This is the first study to show that serum sclerostin and soluble TNF-related weak inducer of apoptosis are elevated in glomerulonephritis patients, and these two markers correlate with arterial stiffness and proteinuria in these patients. Considering the effects of sclerostin and soluble TNF-related weak inducer of apoptosis in patients with glomerulonephritis, we think these mechanisms will be the target of both diagnosis and new therapies.

Selecting the Right Plane of Dissection in Thyroidectomy: Along the Recurrent Laryngeal Nerve or the Thyroid Capsule? A Retrospective Analysis

Abstract Introduction Total thyroidectomy remains highly technical, with a significant risk of recurrent laryngeal nerve (RLN) compromise and hypoparathyroidism. After identifying RLN, at the level of the ligament of Berry, local factors may compel the surgeon to either dissect along the nerve or the thyroid capsule. Objective The objective of the present study is to compare these two approaches in terms of outcomes and complication rates. Methods This is a retrospective analysis from September, 2013 to April 2019 of 511 consecutive patients undergoing thyroidectomy. General demographics and disease parameters were recorded. At the discretion of the surgeon and according to the demands of the local operative factors, the patients either had dissection along the RLN or along the thyroid capsule. Perioperative and postoperative parameters such as blood loss, duration of surgery, hospital stay, pain scores, analgesia requirements and complications were recorded. The groups were compared with the Pearson chi-squared test or with the Fisher exact test. A p-value < 0.05 was considered statistically significant. Results The incidence of transient hypocalcaemia and transient RLN compromise were higher when dissection was performed along the nerve as opposed to the plane along the thyroid capsule. Other parameters including operative time, hospital stay, pain scores, analgesia requirement, wound infection, seroma, hemorrhage, and recurrence did not differ between the groups. Subgroup analysis of the patients who presented with complications showed that local factors, malignancy, and extent of surgery correlated positively with complications when dissected along the RLN. Conclusion Dissection along the capsule of the thyroid during thyroidectomy is a safer plane in terms of low rate of transient RLN injury and hypoparathyroidism as opposed to dissection along the nerve.

Comparison of rapid antigen testing and RT-PCR in the diagnosis of COVID-19 in Kashmir division

Background:Accurate diagnosis and widespread use of diagnostic tests with easy accessis important to contain the spread of SARS-CoV-2. A Real-time reverse transcription polymerase chain reaction (RT-PCR) has high cost and can be performed in special laboratories. There have been several easy to perform rapid antigen detection tests developed and recommended to use at point of care for timely detection of positive patients and their isolation to limit the spread of infection. The aim of the study was to compare the cost effectiveness and the role of RT-PCR and rapid antigen testing in diagnosing different suspects of COVID-19.Methods:In this cross-sectional study the data of all the suspected cases who underwent COVID-19 testing over a period of seven weeks at divisional level was used for analysis.Results:The widespread use of rapid antigen testing makes it more cost effective in detecting COVID-19 cases than the highly sensitive and specific RT-PCR testing. Conclusions:Rapid antigen tests can be used as a screening testing tool in high-risk groups to identify the infected persons quickly and for preventing the transmission of infection particularly in low resource settings.

Pharmaceutical co-crystals of posaconazole for improvement of physicochemical properties

Abstract Posaconazole exerts an extended spectrum of antifungal activity against various strains of clinically relevant moulds and yeasts. In recent years, antifungal triazole posaconazole has become increasingly important for the prophylaxis and treatment of systemic mycoses. After oral administration of posaconazole, absolute bioavailability has been estimated to range from 8% to 47%. Pharmaceutical co-crystallization is a promising approach for improving dissolution rate or manipulating other physical properties of API. The objective of this study is to improve the dissolution rate of posaconazole by co-crystallization. A 1:1 stoichiometric co-crystals of adipic acid were prepared by solvent assisted grinding method. The prepared co-crystals were subjected to solid-state characterization by FTIR, PXRD and DSC studies. The physicochemical properties of posaconazole and co-crystals were assessed in terms of melting point, flowability and dissolution rate. The results indicated improvement in flow property and dissolution rate. In vitro dissolution profile of co-crystals showed a significant increased dissolution of posaconazole from initial period in 0.1 N hydrochloric acid solution. The dissolution efficiency for posaconazole-adipic acid co-crystal was 61.65 % against posaconazole, 46.58 %. Thus, co-crystallization can be a promising approach to prepare posaconazole-adipic acid co-crystals with improved physicochemical properties.

Proposed Pathway Linking Respiratory Infections with Depression

Depression is one of the most important causes of disability and loss of useful life of people around the world. Acute respiratory infection caused a large number of severe illnesses and deaths of the world and most of these due to viral infections, which is estimated more than 80% of respiratory infections. Detection of viruses by immune pathogen recognition receptors activates the intracellular signaling cascade and eventually cause produces interferons. Inflammatory process begins with secretion of interferons and the expression of interferon-stimulated genes. One of the most important of these genes is indoleamine-pyrrole 2,3-dioxygenase (IDO), which plays a major role in tryptophan catabolism. IDO is an intracellular monomeric enzyme that is also responsible for breaking down and consuming tryptophan in the Kynurenine pathway. Increased inflammation has been linked to decrease tryptophan concentrations and increase kynurenine levels. We tried to explain the role of inflammation by viral respiratory infections in causing depression.

17-alpha hydroxyprogesterone caproate for the prevention of recurrent preterm birth among singleton pregnant women with a prior history of preterm birth: a systematic review and meta-analysis of six randomized controlled trials

To perform a systematic review and meta-analysis of all randomized controlled trials (RCTs) that investigated the clinical benefits of 17-alpha hydroxyprogesterone caproate (17OHPC) in the prevention of recurrent preterm birth (PTB) among singleton pregnant women with a previous history of PTB. We searched four major databases up till April 2021 and assessed the risk of bias in the included studies. We meta-analyzed various maternal-neonatal endpoints (n=18) and pooled them as mean difference or risk ratio (RR) with 95% confidence interval (CI) using the random-effects model. Six RCTs met the inclusion criteria, comprising 2,573 patients (17OHPC=1,617, control=956). RCTs revealed an overall low risk of bias. The rates of PTB <35 weeks (n=5 RCTs; RR, 0.77; 95% CI, 0.63-0.93; P=0.008), PTB <32 weeks (n=3 RCTs; RR, 0.68; 95% CI, 0.51-0.91; P=0.009), neonates with low birth weight (<2.5 kg) at delivery (n=3 RCTs; RR, 0.63; 95% CI, 0.5-0.79; P<0.001), and neonatal death (n=4 RCTs; RR, 0.41; 95% CI, 0.20-0.84; P=0.02) were significantly reduced in the 17OHPC group compared with the control group. Moreover, 17OHPC treatment correlated with a significantly decreased rate of retinopathy (n=2 RCTs; RR, 0.42; 95% CI, 0.18-0.97; P=0.004). However, there were no significant differences in the rates of neonatal intensive care unit admission, cesarean delivery, and other pretermrelated complications between both the groups. Among singleton pregnant women with a prior history of PTB, 17OHPC may favorably decrease the risks of recurrent PTB and reduce the rate of neonatal death.

Effectiveness of simplified predictive intubation difficulty score and thyromental height in head and neck surgeries: an observational study / Eficácia do escore simplificado preditivo de dificuldade de intubação e da altura tiromentoniana em cirurgias de cabeça e pescoço: estudo observacional

Abstract Background and objectives: In this study, we aimed to investigate the predictive value of different airway assessment tools, including parts of the Simplified Predictive Intubation Difficulty Score (SPIDS), the SPIDS itself and the Thyromental Height Test (TMHT), in intubations defined as difficult by the Intubation Difficulty Score (IDS) in a group of patients who have head and neck pathologies. Methods: One hundred fifty-three patients who underwent head and neck surgeries were included in the study. The Modified Mallampati Test (MMT) result, Thyromental Distance (TMD), Ratio of the Height/Thyromental Distance (RHTMD), TMHT, maximum range of head and neck motion and mouth opening were measured. The SPIDSs were calculated, and the IDSs were determined. Results: A total of 25.4% of the patients had difficult intubations. SPIDS scores >10 had 86.27% sensitivity, 71.57% specificity and 91.2% Negative Predictive Value (NPV). The results of the Receiver Operating Curve (ROC) analysis for the airway screening tests and SPIDS revealed that the SPIDS had the highest area under the curve; however, it was statistically similar to other tests, except for the MMT. Conclusions: The current study demonstrates the practical use of the SPIDS in predicting intubation difficulty in patients with head and neck pathologies. The performance of the SPIDS in predicting airway difficulty was found to be as efficient as those of the other tests evaluated in this study. The SPIDS may be considered a comprehensive, detailed tool for predicting airway difficulty.

Introduction:This study aimed to assess the incidence, microbiological features and management of surgical site infections (SSIs). Methodology:All patients in the surgical ward were followed from admissions until discharge during the study period. Only hospitalized patients with certain SSIs within 30 days of surgeries were included in the study. Results:A total of 457 patients were followed during the study period. Interestingly, only 9 (1.9 %) of the patients developed SSIs. Most of the patients were males 6 (66.7%) and Saudi nationals 7 (77.8 %). The most common surgical procedures were laparoscopic and orthopedic surgeries with a similar rate of 3 (3.3 %).Conclusion:This study revealed that the incidence of SSIswas quite lower atthe hospital where the study was conducted and different types of antibiotics were used and recommended for prophylaxis

Profile of dog bite injuries in patients presenting at Kimberley Hospital Complex's emergency and gateway centres, 2015 to 2017

Background: Dog bite injuries in humans remain a public health problem. There is limited nationally representative data on the magnitude of the problem and the epidemiological profile of dog bite injuries in South Africa. Aim: To describe the profile of dog bite injuries in patients presenting to Kimberley Hospital Complex (KHC) emergency and gateway centres. To determine the prevalence of dog bite injuries amongst all patients presenting to these centres and the compliance of mandatory notification of dog bites. Setting: Kimberley Hospital Complex emergency and gateway centres. Methods: A retrospective review of all dog bite cases who presented to KHC from August 2015 to July 2017. The total number of all patients who presented were taken into consideration for calculating the prevalence of dog bite cases. Results: During the study period, 433 dog bite cases were identified out of 107 731 patients seen at emergency and gateway centres, giving a prevalence of 0.4%. Of all cases, 62.4% were male patients and 37.6% were female patients. Most affected age group was between 10 and 19 years (19.6%). Category II exposure type accounted for the majority of the cases (59.4%). Unvaccinated dogs were incriminated in 61.9% of cases. Stray dogs were responsible for 83.1% of all injuries. More than half of the cases (47.9%) were notified by the treating doctors. Conclusion: Dog bite injuries in Kimberley were commonest in children and adolescents. The prevalence tended to decrease in adulthood with advancing age groups. Most bites resulted from unvaccinated stray dogs. Only about half of the cases were notified to the appropriate authorities. Prevalence of dog bite injuries amongst patients presenting at KHC resulted in the low rate of 0.4%. Awareness needs to be created amongst health care providers on the importance of notification of all exposure to rabies. More efforts are required at the prevention of dog bites in children and adolescents through stringent measures to limit the number of free-roaming dogs

Concordance between tuberculin skin test and interferon-gamma release assay for latent tuberculosis screening in inflammatory bowel disease

Background/Aims@#Latent tuberculosis screening is mandatory prior to initiating anti-tumor necrosis factor (anti-TNF) medications. Guidelines recommend interferon-gamma release assays (IGRA) as first line screening method for the general population. Studies provided conflicting evidence on IGRA and tuberculin skin test (TST) performance in inflammatory bowel disease (IBD) patients. We assessed test concordance and the effects of immunosuppression on their performance in IBD patients. @*Methods@#We searched MEDLINE, Embase and Cochrane databases (2011–2018) for studies testing TST and IGRA in IBD. Primary outcome was TST and IGRA concordance. Secondary outcomes were effects of immunosuppressive therapy on performance. Immunosuppression defined as either steroids, thiopurine, methotrexate or cyclosporine use. We used the pooled random effects model to adjust for heterogeneity analyzed using (I2–Q statistics). We compared the fixed model to exclude smaller study effects. @*Results@#Sixteen studies (2,488 patients) were included. Pooled TST and IGRA concordance was 85% (95% confidence interval [CI], 81%–88%; P=0.01). Effects of immunosuppression were reported in 8 studies (814 patients). The odds ratio of testing positive by IGRA decreased to 0.57 if immunosuppressed (95% CI, 0.31–1.03; P=0.06). The odds ratio of testing positive by TST if immunosuppressed was 1.14 (95% CI, 0.61–2.12; P=0.69). The fixed model yielded similar results, however the negative effect of immunosuppression on IGRA reached statistical significance (P=0.01). @*Conclusions@#While concordance was 85% between TST and IGRA, the performance of IGRA seems to be negatively affected by immunosuppression. Given the importance of detecting latent tuberculosis prior to anti-TNF initiation, further randomized controlled trials comparing the performance of TST and IGRA in IBD patients are needed.

Histologically confirmed upper gastrointestinal Crohn’s disease: is it rare or are we just not searching hard enough?

Background/Aims@#Crohn’s disease (CD) may involve the upper parts of the gastrointestinal (GI) tract including the esophagus, stomach, and duodenum. Clinical features of upper GI CD (UGICD) are not well characterized in the Gulf region. We therefore aimed to assess the prevalence and clinical characteristics of patients diagnosed with UGICD. @*Methods@#We performed a retrospective analysis of all patients diagnosed with CD who underwent upper GI endoscopy between 2012 and 2017 at King Abdulaziz University Hospital, irrespective of age. Patients who had endoscopy of the upper GI tract at baseline and had histologically confirmed UGICD were included. Data on patients’ demographics, clinical characteristics, extraintestinal manifestations and complications were reviewed. @*Results@#We identified 78 CD patients who underwent upper GI endoscopy from our medical records. The mean age was 17.2±8.7 years and 55.1% were males. Of the total, 19 out of 78 patients (24.4%) had histologically confirmed UGICD (3 esophageal, 16 gastric, and 9 duodenal), of which 52.6% were symptomatic. Disease distribution was ileal in 57.8%, colonic in 21.1% and ileo-colonic in 21.1%. A non-stricturing and non-penetrating phenotype was reported in 89.4%, stricturing in 5.3%, and penetrating in 5.3%. Perianal disease was found in 10.5%. UGICD was complicated by stricture formation in 2 patients (esophageal and gastric). @*Conclusions@#The prevalence of UGICD is considered high among CD Saudi patients who undergo upper GI endoscopy at baseline, and is asymptomatic in 47.4% of patients. This reported prevalence is not dissimilar from reports originating from Western countries.

E-Cadherin as a Marker for Nodal Metastasis in Head and Neck Squamous Cell Carcinoma

Aim: Head and neck cancers, all over the world, contribute greatly to the number of deaths, despite the advancements in the therapeutic strategies. It is characterized by locoregional disease with a tendency for metastasis to the cervical lymph nodes. The pre-operative detection of lymph node metastasis is critical for the effective treatment of patients with head and neck squamous cell carcinoma. Therefore the objective of this study was to identify E-cadherin as a marker for prediction of lymph node metastasis in head and neck squamous cell carcinoma (HNSCC).Study Design:Cross-sectional study.Place and Duration of Study: Dow University of Health Sciences, Karachi. 1 Year duration.Methodology:Cross-sectional analysis of 54 subjects with HNSCC, who underwent neck dissections, was carried out. Expression of E-cadherin was evaluated using immunohistochemical analysis and traditional histological parameters, and correlation of E-Cadherin with histologically verified presence of regional metastases was determined. Data was subjected to descriptive statistics and chi-square using Spss v.16.0.Results:54 patients included 33 males (61.1%) and 21 females (38.9%) aged from 18 to 73 (mean 44.8±12.7). A statistically significant relationship between the Downregulation of E-cadherin and histologically verified presence of nodal metastasis was established. (p value= 0.01).Conclusion:This study shows that low E-cadherin expression is useful for predicting lymph node metastases in cases of head and neck carcinoma.

A Cross-Sectional Survey to Assess Knowledge, Attitude, and Practices in Patients with Hypothyroidism in Riyadh, Saudi Arabia

Background: Without corrective action, patients suffering from hypothyroidism may exhibit increased risk ofcardiovascular diseases, dysrhythmias and fractures, and are also at risk of adverse effects on bone mass, lipidmetabolism, blood pressure, and a declined cognitive function. Methods: We adopted a cross-sectional survey toassess the knowledge, attitude, and practices in patients with hypothyroidism in Riyadh, Saudi Arabia.Participants for the study were recruited from 04/08/2019 till 24/09/2019 through convenience sampling method.For an individual to participate in the study, they were required to be 18 years of age and diagnosed withhypothyroidism, a Saudi citizen and a resident of Riyadh. The participants were assessed on a number ofindicators; demographics, questions on knowledge domain, questions on attitude domain, and questions onpractice domain. In our construct, the knowledge section consisted of 20 factual statements to assess variousindicators of hypothyroidism, including the symptoms, risk factors, diagnosis, and treatment. Results: 55% of therespondents were female and 45% were male. The study indicates that hypothyroidism occurs at a higherprevalence in females in the 45+ age category, which is consistent with previous literature. Equally, 24% of therespondents strongly disagree that women are at a greater risk of developing hypothyroidism and should be testedat regular intervals for hypothyroidism; while, 19% of the respondents agree that women are at a greater risk ofdeveloping hypothyroidism and should be tested at regular intervals for hypothyroidism. The findings indicate aworrying lack of knowledge about hypothyroidism among residents of Riyadh. Conclusion: There is a need forgreater public education and awareness in Saudi Arabia to improve the level of knowledge about hypothyroidism.

Method: sixty patients of ADHD and 60 age and sex matched control were evaluated with EEG to detect abnormal waves. Results: Patients with ADHD show abnormal EEG results in the form of background slowing in3 patients (5%) and epileptiform discharge in 19 patients (32%) frontal slowing in 13 patients(22%) normal EEG in 25 patients (42%).Conclusion: There is increased low frequency activity and decreased high frequency activity in children with ADHD, this may aid as an indicator in the diagnosis of ADHD

Effect of Isoflavones and Genistein on Glucose Metabolism in Peri- and Post-Menopausal Women: An Overview of Meta-Analysis

The purpose of the present overview of meta-analysis is to summarize and critically assess the effect of isoflavones and genistein on glucose metabolism among the peri- and post-menopausal women. Two independent authors searched the databases of MEDLINE, Scopus and Cochrane Library for meta-analysis. Three databases were searched from inception to January 2018. Methodological quality of each meta-analysis of randomized controlled trials was evaluated using the AMSTAR (a measurement tool used to assess systematic reviews). Four meta-analyses were included to the current overview. Fasting insulin levels and homeostatic model assessment of insulin resistance (HOMA-IR) values were significantly lower in peri-menopausal and postmenopausal. Two meta-analyses showed that treatment with isoflavones could not alter fasting blood glucose. However, one meta-analysis depicted that isoflavones significantly improved blood glucose levels in non-Asian postmenopausal women. Treatment with genistein could have significant beneficial effects on fasting insulin, blood glucose and HOMA-IR in comparison to the control group. Regardless of the population, the treatment with genistein is effective in improving fasting insulin, HOMA-IR and glucose levels. Nevertheless, the high heterogeneity among studies and poor methodology of reviews made it difficult to draw a definite conclusion on the positive impacts of soy on glucose metabolism.

Effect of Lavender on Sleep, Sexual Desire, Vasomotor, Psychological and Physical Symptom among Menopausal and Elderly Women: A Systematic Review

OBJECTIVES: The present systematic review was conducted to compare the effect of lavender on the quality of sleep, sexual desire, and vasomotor, psychological and physical symptoms among menopausal and elderly women. METHODS: There were five electronic databases which selected to search respective articles which included were Scopus, PubMed, Web of Science, Google Scholar, and the Cochrane Library without any language restriction since the study inception to March 10, 2018. The quality of studies was assessed in accordance with a jaded scale. RESULTS: According to three trials, the lavender as utilized in a capsule form or aromatherapy could significantly improve the measured Pittsburgh Sleep Quality Index score (P < 0.05) in the menopausal and elderly women. The aromatherapy with lavender improved sexual function (P < 0.001), depression (P < 0.001), anxiety (P < 0.001), and physical (P < 0.001) symptoms. Based on a trial, 66.7%, 70.0%, and 53.3% of subjects reported feelings of relaxation, happiness, and cleanness effects of having used lavender respectively. CONCLUSIONS: The results suggested the effectiveness of the use of lavender either in capsule form or aromatherapy on the improved quality of sleep, depression, anxiety, sexual desire, and psychological and physical symptoms. These results, however, should be interpreted with caution considering the limitations of the study.

Clinical Study of Acid-Peptic Disease in a Semi-Urban Setup in Western Uttar-Pradesh

Background: Acid peptic disease is a common morbidity is India. We aim to find the present dynamics of age, sex and causative factors in our semiurban setup in western Uttar-Pradesh. Methods: a prospective study was done to include patients with acid peptic like symptoms presenting between January 2016 to December 2017. Upper GI endoscopy was done in patients with severe and recurrent symptoms. Results: In our study, out of 488 patients, 24 presented with perforated ulcers while 255 patients underwent upper GI endoscopy. 42 patients had normal mucosa on endoscopy. Highest incidence was seen in the age group of 31-40 years.68.86% of the patients had some sort of tobacco or alcohol intake. Conclusion: Peptic ulcer disease is still associated with considerable morbidity even in this era of proton pump inhibitors and H2 receptor blockers available as OTC products. The highest incidence was in the age group of 31-40 years. Lifestyle factors like smoking, alcohol intake, spicy, oily and salty food intake and tobacco chewing are present in majority of patients. Incidence of the disease in females is seen to be increasing.

Assessment of flatulence causing agents in Chickpea (Cicer arietinum L.) and their possible removal

Abstract Flatulence and fullness of stomach is one of the most common problem associated with chickpea primary due to presence of some oligosaccharides and phenols. In this investigation Desi and Kabuli varieties were compared for these oligosaccharides and phenolic compounds. Furthermore, the effect of different processing and cooking methods such as soaking, cooking and germination in the reduction of these antiphysiological factors were are also studies. Maximum tannic acid (0.90 ± 0.20%) was observed in Parbat and C-44 while minimum (0.60 ± 0.04%) in Karak-2. Stachyose contents ranged between 1.10 ± 0.05 (Karak-3) to 1.42 ± 0.02% (Parbat) while raffinose was 0.63 ± 0.05(Karak-3) to 0.81 ± 0.02% (Dasht). The highest tannic acid content was reduced up to 50% in C-44 by cooking of 72 hours germinated seeds. Stachyose and raffinose contents were completely removed after 72 hours germination. Present studies revealed that cooking after germination is the most effective method to reduce the anti-nutritional factors of chickpea. Individually, soaking and cooking also contributed to the loss of the same factors but to a lesser extent.

Prunus domestica alters functions of frog's heart

Prunes could exert cardiovascular protective effects. Trials have demonstrated antihypertensive effects of Prunus domestica. The aim of this study was to find out if prunes could alter cardiac functions that may help understanding the mode of control of hypertension. Changes in rate and contractile force of frogs' heart were recorded using Power Lab. Effects of prunes' extracts: aqueous [10, 20, 40%]; methanolic, acetonic, ethanolic and chloformic [10%]; were evaluated and compared with other drugs. We tested effects of acetylcholine and atropine [10-5], adrenaline, propranolol, verapamil and diltiazem [10[-3]]; NaC1, KCl, CaC1[2], MgC1[2] [10% w/v] on frog's heart alone and with prunes/drugs. All extracts of prunes significantly reduced HR and contractile force. Prunes combined with acetylcholine, propranolol or verapamil significantly enhanced bradycardia; whereas it blocked tachycardia produced by epinephrine, atropine or calcium; moreover prunes blocked the significant increase in HR and cardiac contractility produced by CaCl[2]; and reduced HR along with MgC1[2]. NaCl and KCl alone or with prunes had non-significant effects on frog's heart. In conclusion, Prunus domestica plays a key role in modification of intracellular Ca+2 concentration resulting in negative ionotropic and chronotropic effects [similar to cholinergic stimulation and adrenergic or calcium channel blockade] that could lead to hypotensive effects

Prevalence of mecA: Genotyping screening of community acquired- MRSA isolates in Karachi, Pakistan

Among resistant nosocomial and community pathogens, MRSA has become the most serious pathogen, causing life threatening infections worldwide. In S.aureus, quick and exact recognition of methicillin [cefoxitin] resistance has become essential. The benchmark for MRSA identification among S.aureus is the detection of the mecA gene that causes the expression of protein [PBP2a] culpable for classic â-lactam resistance. However, the utter reliance on amplification of mecA gene as a hallmark in confirmation of methicillin [cefoxitin] resistant S. aureus is the matter of distrust by some investigators. The current investigation designed to analyse the prevalence of mecA gene among phenotypically positive MRSA isolates using molecular method and to correlate its prevalence to conventional techniques. Furthermore, antimicrobial sensitivity of mecA positive staphylococci was determined by Kirby Baeuer method. For this purpose, 201 clinical staphylococcal specimens were recovered from various diagnostic laboratories in Karachi City, Pakistan. Phenotypic existence of methicillin resistance in S. aureus was observed to be 51.7%. In contrast, when organisms were subjected for amplification of mecA gene by PCR, mecA positive isolates were 36/104 [35%] MRSA isolates. Current work raise question towards the usefulness of molecular identification of mecA gene in confirmation of methicillin resistance without correlating with conventional methods. Therefore, it is essential to consider the other possible resistance mechanisms for Beta-lactams that may interact with mecA gene in the development of methicillin resistance mechanism in Staphylococcus
