RESUMO
Background@#Atrial tachycardia poses challenges in patient management due to the associated risks of stroke and systemic embolism. While anticoagulation is recommended in atrial fibrillation (AF), its role in atrial tachycardia remains less defined. This prospective study aimed to evaluate the efficacy and safety of apixaban, a direct oral anticoagulant, in individuals diagnosed with left-sided atrial tachycardias. @*Methods@#Patients diagnosed with left-sided atrial tachycardia (n = 439) were observed over 3 years. Baseline characteristics, medication regimens, and clinical outcomes were assessed. Apixaban-treated individuals (n = 213) received standard or reduced dosages, while the control group (n = 226) received standard care. Primary outcomes included stroke, systemic embolism, bleeding, and mortality rates. @*Results@#Baseline characteristics were comparable between groups. The apixaban cohort showed a lower incidence of stroke (7.0% vs. 9.3%, p = 0.027) and decreased all-cause mortality (11.7% vs. 12.8%, p = 0.012) compared to controls.No significant differences were found in major bleeding or systemic embolization between groups. @*Conclusion@#Apixaban demonstrated a potential benefit in reducing stroke and mortality rates in patients with leftsided atrial tachycardia. While requiring further validation, these findings suggest a potential role for apixaban in anticoagulation strategies for atrial tachycardia management.

Which are potent to the attract governments attention. Environment and wildlife are subject to the harmful impacts of mining and its related activities. In this study, districts, namely Mardan and Mohmand have been targeted with respect to mining impacts. The assessment was carried out on wildlife adversely affected by the mining sector. The fauna has been keenly observed to bring the calculated risks and threat perception of the regional wildlife. Total 9 species of mammals, 21 species of birds, were recorded in District Mardan. While in District Mohmand 2 species of mammals, 9 species of birds, and 4 species of reptiles were studied. The Study explored that mining primarily responsible for land degradation. Which lead to food and agriculture losses. Several other factors like blasting, pollution, hunting, deforestation, habitat loss was also observed. Deforestation surfaced one of the major causes for extinction of fauna in the said region. preemptive measures are needed to seize the man-made catastrophe.
Resumo A mineração é vital para o sustento humano e um setor crucial na economia do Estado. No entanto, seus impactos sobre o meio ambiente e a biodiversidade não podem ser subestimados, visto serem potentes para atrair a atenção do governo. O meio ambiente e a vida selvagem estão sujeitos aos impactos prejudiciais da mineração e de suas atividades relacionadas. Neste estudo, os distritos, nomeadamente Mardan e Mohmand, foram selecionados no que diz respeito aos impactos da mineração. A avaliação foi realizada em animais selvagens afetados negativamente pelo setor de mineração. A fauna tem sido observada atentamente para trazer os riscos calculados e a percepção de ameaça à vida selvagem regional. Um total de nove espécies de mamíferos, 21 espécies de pássaros, foi registrado no Distrito Mardan. Enquanto no Distrito Mohmand, duas espécies de mamíferos, nove espécies de pássaros e quatro espécies de répteis foram estudadas. O estudo explorou essa mineração que é principalmente responsável pela degradação do solo, acarretando perdas de alimentos e na agricultura. Vários outros fatores como explosões, poluição, caça, desmatamento, perda de habitat também foram observados. O desmatamento veio à tona como uma das principais causas de extinção da fauna da região, e tem-se que medidas preventivas são necessárias para dimensionar a catástrofe provocada pelo homem.
RESUMO
Abstract Introduction Allergic rhinitis (AR) is estimated to affect up to 30% of the world population. With the rise in cases, newer treatment modalities have been explored. Probiotics have shown to reduce symptoms of AR and improve quality of life. A few systematic reviews have been published aiming to assess the role of probiotics in AR. Objectives To consolidate the recent evidence with an overview of systematic reviews by extracting data regarding subjective outcomes (from quality of life questionnaires, the Total Nasal Symptom Score, the Total Ocular Symptom Score, the Daily Total Symptom Score, the incidence of AR, and the Rhinitis Total Symptom Score) and objective outcomes (levels of antigen-specific immunoglobulin E [IgE], total IgE, interleukin 10 [IL-10], interferon gamma [IFNG], eosinophil, and the T helper 1/T helper 2 [Th1/Th2] ratio). Data Synthesis We conducted a literature search on the PubMed, EBSCO CINAHL, EBSCO Dentistry & Oral Sciences Source, and Cochrane Library up to April 14, 2020. The qualitative assessment was performed using the Assessing the Methodological Quality of Systematic Reviews (AMSTAR-2) tool. A total of 419 titles were screened, and 3 systematic reviews met our eligibility criteria. Probiotics in the treatment of AR have been shown to improve quality of life, the total nasal and ocular symptom scores, the daily total symptom scores and Th1/Th2 ratio. No difference was ascertained for rhinitis total symptom score, and the rates of antigen-specific IgE, total IgE, IL-10, INFG and eosinophil. Conclusion The present review showed that there is considerable evidence that probiotics are useful in the treatment of AR. Further randomized trials targeting the limitations of the currently-available evidence can help ascertain the usefulness of probiotics in cases of AR.
RESUMO
Background: Periodontitis is a multi-factorial chronic inflammatory disease of attachment apparatus of teeth with microorganisms playing a major role. To address periodontal disease various strategies have been adopted to target these periodonto-pathogens. Various antimicrobial drugs (systemic as well as local) are effectively used to control the disease. However due to various side effects ofsystemic administration of the drugs like gastro intestinal disturbances, development of resistant organisms, high dosage of the drug required, local delivery of the drug is a better option as the drug is directly delivered at the site of infection with minimum dosage and maximum response achieved thus eliminating all the undesired effects of the drug. Aim: To evaluate the efficacy of 10% povidone iodine with 2% metronidazole and 1% ornidazole with 0.25% chlorhexidine gel as local delivery systems for the reduction in the pocket depth, changes in CAL, gingival inflammation. Materials and methods: A total of 20 patients diagnosed with mild- moderate chronic periodontitis were divided into two groups in a split-mouth study design - Group I and Group II with each group containing 20 sites with probing depth of >5 mm, CAL ?3 mm. In Group I, 10% povidine-iodine gel with 2% metronidazole was delivered inside the pocket and Group II, 1% ornidazole with 0.25% chlorhexidine was used as a local delivery system in adjunct to scaling and root planning. In both groups, medications were delivered at weekly interval for a period of 4 weeks. Baseline and 4 weeks measurements were done and compared for probing pocket depth (PPD), clinical attachment levels (CAL) and gingival inflammation. Results: The results obtained were statistically analyzed. Both groups showed statistically significant improvements in terms of clinical parameters. However, there was statistically insignificant difference when compared between the two groups. The results clearly demonstrate that both povidone iodine with metronidazole and ornidazole with chlorhexidine are also useful in controlling the acute phase of the periodontal disease in adjunct to scaling and root planning (SRP). Conclusion: Both drugs when used as an adjunct to scaling and root planning enhances probing pocket depth reduction, change in clinical attachment levels and gingival inflammation in mild- moderate chronic periodontitis cases.
RESUMO
Background: Management of gingivitis is commonly done by the removal of etiological agents by Periodontist. However, use of topical applications of antibiotic combinations has been shown to improve the treatment outcome. Various drugs alone or in combination have been used. So this study was conducted to determine the effect of different concentrations of combination drugs on gingivitis.Material & Methods:100 patients of gingivitis were divided into two groups of 50 each – Group-A and Group-B. After scaling and root planing, Group-A patients were made to apply Metronidazole 1% and Chlorhexidine 0.25% for period of 12 weeks while as Group-B patients applied Metronidazole 1.5% and Chlorhexidine 0.50% for 12 weeks. Baseline scores of gingival index and bleeding index were recorded followed by readings at 4 and 12 weeks.Results:Results showed that there was a significant improvement in gingivitis and bleeding on probing at 4 and 12 weeks after local application of Metronidazole and Chlorhexidine gel in both the groups. However there were no statistically significant differences between two groups.Conclusions:Topical application of Metronidazole and Chlorhexidine gel as an adjunct to scaling and root planing is an effective treatment modality for the management of gingivitis and the concentrations of the combination do not have any significant effect on the treatment.

RESUMO
Background: Periodontal diseases are characterized by the presence of bleeding, inflammation, sensitivity, discomfort, mobility and tooth loss. Plenty of studies supported the assumption that vitamin D deficiency might be a risk factor for periodontal diseases. Our study aimed to investigate the true association between serum vitamin D level and the presence of periodontal disease. Materials and methods: The study evaluated 40 patients (age group 19-35 years) attending the outpatient department, Department of Periodontics and Implantology, Govt. Dental College and Hospital, Srinagar, equally divided into two groups (Group I and Group II) according to the inclusion criteria. Group I included generalized aggressive periodontitis patients while Group II included non periodontitis patients. Clinical parameters and serum 25-hydroxyvitamin D level were assessed. Results: Serum vitamin D levels of periodontitis patients compared to non-periodontitis patients presented non statistically significant differences (p-value = 0.878). Conclusion: Although the serum vitamin D level in aggressive periodontitis patients was lower than the healthy controls but the difference seemed to be statistically insignificant and hence it can be concluded that the serum vitamin D deficiency is not a risk factor for periodontitis.

RESUMO
@# Objective: To explore the protective role of Glinus lotoides ethanolic extract in a depression model through modulating oxidant/antioxidant enzyme system and inflammatory status. Methods: Phytochemical constituents of Glinus lotoides ethanolic extract were evaluated qualitatively and quantitatively along with HPLC. Rats were divided into six groups. The normal control and the intoxicated groups received normal saline, and the standard group received imipramine, while the remaining groups received 100, 300, and 500 mg/kg Glinus lotoides ethanolic extract. All groups received treatments for 14 d. Lipopolysaccharides (LPS) were then administered i.p. (0.83 mg/kg) to all groups except the normal control group. After 24 h, anxiety and depression-like behaviors were evaluated by performing behavioral analysis (open field, tail suspension, forced swim, sucrose preference test), and determining total oxidant status, total antioxidant capacity, catalase, and biochemical parameters [malondialdehyde, glutathione, superoxide dismutase, tumor necrosis factor (TNF)-alpha and interleukin (IL)-6]. Results: Phytochemical studies confirmed the presence of phenols and flavonoids and HPLC analysis showed the presence of gallic acid, quercetin, chlorogenic, and caffeic acid. Total oxidant status was significantly decreased, while total antioxidant capacity was significantly increased in the Glinus lotoides ethanolic extract treated groups. Moreover, Glinus lotoides ethanolic extract diminished malondialdehyde, IL-6, and TNF-alpha levels, while increasing superoxide dismutase, catalase, and glutathione activities. Conclusions: Glinus lotoides ethanolic crude extract shows significant antidepressant activity by modulating oxidative and biochemical parameters that supports its folkloric use in traditional systems of medicine.

Abstract Introduction Parotid gland tumors include a wide variety of inflammatory and neoplastic diseases. The majority of these tumors are benign (80%), which usually require superficial parotidectomy, while the incidence of malignant tumors is lower (20%), requiring more radical surgery with or without neck dissection. The diagnosis cannot be established on the basis of clinical history and simple physical examination and requires complementary diagnostic methods. Fine needle aspiration cytology (FNAC) guided by ultrasound is a widely used diagnostic tool to evaluate parotid swellings. Objective To determine the sensitivity, specificity, positive and negative predictive values and diagnostic accuracy of FNAC in the diagnosis of parotid gland tumors. Methods A retrospective chart review of 193 patients who underwent preoperative FNAC and parotidectomy at the Aga Khan University Hospital, Karachi, Pakistan, from the period of January 2000 to December 2015 was performed. Results Out of 193 patients undergoing parotidectomy, 110 (57%) were males and 83 (43%) were females, the mean age being 48.21 and 43.76 years old, respectively. The mean duration of the symptoms was 41.33 months, and the most common symptom was preauricular swelling present in all patients, followed by pain, which was present in 29 patients (15%) and facial nerve weakness in 6 patients (3.1%). Fine needle aspiration cytology was performed preoperatively and the results were compared with the final histopathology, which showed sensitivity of 88.9%, specificity of 97.9%, positive predictive value of 93%, negative predictive value of 96.7% and diagnostic accuracy of 95.8%. Conclusion Our results suggest that FNAC is relatively an accurate method for preoperative diagnosis of parotid swelling and can prove to be a valuable tool for preoperative counseling of the nature of the disease and prognosis.

RESUMO
Abstract Introduction Tumors of the parotid gland are heterogeneous. The purpose of the drain placement is to evacuate fluid that has a potential to accumulate in the dead space and cause infection after parotidectomy. Objectives To evaluate the factors associated with drain output among patients submitted to parotidectomy. Methods A retrospective cohort study was conducted in the Department of Otolaryngology/Head and Neck Surgery at the Aga Khan University Hospital, Karachi, from January 1994 to December 2014. Patients who underwent parotidectomy were included in the study. Linear regression analysis was used to determine the factors associated with drain output. Results A total of 193 patients were included in the study. The mean age of the patients was 46.3 years, and 57% of them were male. Length of surgery (β coefficient = 24.2; 95% confidence interval [95%CI]: 4.94-85.26), type of neck dissection (modified radical neck dissection: β = 93.9; 95% CI: 30.47-157.38; selective neck dissection: β = 79.9; 95%CI: 29.04-126.85), and type of parotidectomy (total β = 45.1; 95%CI: 4.94-85.26) were factors that significantly influenced drain output in patients submitted to parotidectomy with or without neck dissection. Conclusion Neck dissection, total parotidectomy and length of surgery were predictors of postoperative neck drainage in our cohort. These factors can help predict postoperative neck drain output and help in patient counselling.

RESUMO
ABSTRACT Introduction: Multiple myeloma (MM) is a common hematologic malignancy with variable degrees of immunodeficiency. Disease- and treatment-related compromise of the immune system predisposes patients to infections, which are a major cause of morbidity and mortality. Objective: We aimed to establish the incidence and main characteristics of infections in MM patients treated at our center over a 10-year period. Method and results: Of the 412 patients retrospectively analyzed, 154 (37.4%) were documented to have at least one episode of infection and were included in this study. A total of 244 infectious episodes were documented. The most common site of infection was the lung, followed by the genitourinary system. The most common infections were bacterial, followed by viral. Escherichia coli were the most common organism. In 160 (65.5%) episodes, the organism was not isolated. Thalidomide with dexamethasone was the most common treatment regimen, followed by melphalan with dexamethasone. Infection was the main cause of death in 26 (6.3%) out of all 412 patients. Conclusion: Infections are a notable cause of morbidity and mortality in the clinical course of MM patients. By considering patient and disease characteristics, a risk-adapted selection of the MM treatment should be employed, with special attention toward patient age and disease-associated organ dysfunction. Patient education, access to healthcare and physician vigilance are also essential. Vaccination and antimicrobial prophylaxis may be considered prior to or during therapy.

Introduction: The natural history of diabetic nephropathyhas generally been viewed as a descending path fromnormoalbuminuria to end stage renal disease through anintermediate stage marked by microalbuminuria and overtproteinuria. For this reason, measurement of urine albuminis often used as a sensitive marker and predictor of overtnephropathy in patients with diabetes mellitus. Study aimedto determine the prevalence of microalbuminuria in newlydiagnosed type 2 diabetes mellitus patients and to assess theprobable risk factors associated with microalbuminuria.Material and methods: A total of 155 newly diagnosed Type 2Diabetes mellitus patients were includedin our cross-sectionalstudy. After the history, general physical examination andanthropometry, various biochemical investigations includingkidney function test, plasma blood sugars, lipid profile andHbA1c. The detection of microalbuminuria was done byMicral Test (dipstick, Roche Diagnostic) method in a randomspot urine sample. Microalbuminuria was diagnosed if theurinary albumin excretion was ≥20 mg/L of urine.Results: The overall prevalence of nephropathy was 32.9%(51/155).There was significant association of albuminuriawith the increase in age of the patients, increased BMI, highglycated haemoglobin, high fasting plasma glucose, anddyslipidemia.Conclusion: A relatively high prevalence of microalbuminuriaat the time of diagnosis in our study reconfirms that evaluationfor microalbuminuria must be done at the time of diagnosis inall patients of T2DM
