RESUMO

Introduction: Shaping up the post-2015 development agenda is of crucial importance in the development process around the Globe as 20151 was the last year of milllenium development goals. It is the right time to asses our own progress vis-a-vis the Millennium development goals. Appropriate feeding and weaning practices are the key contributor for decreasing morbidities and mortalities in under-five children. As per national family health survey-5 (NFHS-5), only 55.8% of the Indian infants between 0 and 6 months were exclusively breastfed in Gujarat. Children age 6-8 months receiving solid or semi-solid food and breast milk were only 49.4% in Gujarat. Only 5.8% of breastfeeding infants aged 6-23 months receive an adequate diet in Gujarat. Hence the following study was done to know the practice of breastfeeding and weaning in mothers of urban and rural area of Ahmedabad city, Gujarat. Objective: The primary objective of this study was to describe the breastfeeding and newborn care practices and the factors affecting the initiation and duration of breastfeeding in urban and rural areas of Ahmedabad city, Gujarat and the secondary objective was to describe the comorbidities associated with them. Methods: Cross-sectional study was done in anganwadis of slums of urban and rural field practice area of B.J. Medical College, Ahmedabad. Results: Half of the under-five children were provided jaggery as pre-lacteal feed both in urban (45%) and rural (53%) area. In urban area most common reason for providing pre lacteal feeds was due to family customs (55%) followed by their belief that it leads to help in removal of meconium from gut (22%) followed by as advised from their relatives (23%) as compared to in rural area where there was belief that it leads to help in removal of meconium from gut (52%) followed by family customs (31%) and advise from relatives (17%). There were 7.5% under-five children in urban area in whom breastfeeding was not initiated immediately compared to rural area in which there were 42% under-five children. Conclusion: Frequent occurrence of acute illness among under-fives may have lead to undernutrition.

RESUMO

BACKGROUND: In this first-in-human phase 1 study (NCT02964013; MK-7684-001), we investigated the safety and efficacy of the anti-TIGIT (T cell immunoglobulin and ITIM domain) antibody vibostolimab as monotherapy or in combination with pembrolizumab. PATIENTS AND METHODS: Part A enrolled patients with advanced solid tumors, and part B enrolled patients with non-small-cell lung cancer (NSCLC). Patients received vibostolimab 2.1-700 mg alone or with pembrolizumab 200 mg in part A and vibostolimab 200 mg alone or with pembrolizumab 200 mg in part B. Primary endpoints were safety and tolerability. Secondary endpoints included pharmacokinetics and objective response rate (ORR) per RECIST v1.1. RESULTS: Part A enrolled 76 patients (monotherapy, 34; combination therapy, 42). No dose-limiting toxicities were reported. Across doses, 56% of patients receiving monotherapy and 62% receiving combination therapy had treatment-related adverse events (TRAEs); grade 3-4 TRAEs occurred in 9% and 17% of patients, respectively. The most common TRAEs were fatigue (15%) and pruritus (15%) with monotherapy and pruritus (17%) and rash (14%) with combination therapy. Confirmed ORR was 0% with monotherapy and 7% with combination therapy. In part B, 39 patients had anti-PD-1 (programmed cell death protein 1)/PD-L1 (programmed death-ligand 1)-naive NSCLC (all received combination therapy), and 67 had anti-PD-1/PD-L1-refractory NSCLC (monotherapy, 34; combination therapy, 33). In patients with anti-PD-1/PD-L1-naive NSCLC: 85% had TRAEs-the most common were pruritus (38%) and hypoalbuminemia (31%); confirmed ORR was 26%, with responses occurring in both PD-L1-positive and PD-L1-negative tumors. In patients with anti-PD-1/PD-L1-refractory NSCLC: 56% receiving monotherapy and 70% receiving combination therapy had TRAEs-the most common were rash and fatigue (21% each) with monotherapy and pruritus (36%) and fatigue (24%) with combination therapy; confirmed ORR was 3% with monotherapy and 3% with combination therapy. CONCLUSIONS: Vibostolimab plus pembrolizumab was well tolerated and demonstrated antitumor activity in patients with advanced solid tumors, including patients with advanced NSCLC.

RESUMO

The ascorbate-glutathione (AsA-GSH) cycle is a major pathway of H2O2 scavenging in plants. The effect of diurnal variations in hydrogen peroxide (H2O2) content, the intensity of lipid peroxidation (malondialdehyde, MDA), photosynthesis, antioxidants and antioxidative enzyme activities involved in AsA-GSH metabolism has been studied comparatively in leaves of durum (Triticum durum Desf.) and bread (Triticum aestivum L.) wheat genotypes exposed to soil drought. Drought stress caused an increase in the content of H2O2, MDA, alterations in the activities of AsA-GSH cycle enzymes and quantitative changes in AsA and GSH content during the day. PSII efficiency was significantly lower in the control and drought exposed leaves at the highest temperature in the afternoon. The ascorbate peroxidase activity was found to increase and ascorbic acid amount decreased with increasing temperature during the day. Further, the glutathione amount and glutathione reductase activity increased at the expense of the regeneration of the oxidised form of glutathione. Our results revealed that wheat can tolerate drought stress by enhancing the antioxidant enzyme activities and alteration of the concentration of ascorbate and glutathione.

RESUMO

Management of HIV in India has significantly improved with many international and local programmes supporting prevention and treatment. However, there are areas in India where women and children living with HIV endure a myriad of medical, psychological and social challenges. Women in rural poor areas in India have little control over important aspects of their life. Often, they have little decision-making powers within their families on matters that affect them personally. They find themselves unable to negotiate to protect themselves from harm or risk of infection. Those who are known to have contracted HIV are reluctant to access health care for fear of discrimination and marginalization, leading to a disproportionate death rate in HIV women. India is arguably home to the largest number of orphans of the HIV epidemic. These children face an impenetrable barrier in many Indian societies and endure stigmatization. This situation encourages concealment of the disease and discourages children and their guardians from accessing available essential services. This article provides an overview of the relevant literature and presents an insight into a complex mix of issues that arise directly out of the HIV diagnosis, including the role of social attitudes in the spread of HIV, and in creating barriers to accessing care. The review identifies international programmes and local initiatives that have ensured better access to antiretroviral therapy and have led to prolonged survival and reduction in the vertical transmission of HIV in India.

RESUMO

BACKGROUND: Telavancin is approved in the USA and Canada for the treatment of Gram-positive complicated skin and skin structure infections (cSSSIs) based on the results of the Phase 3 Assessment of TeLAvancin in complicated Skin and skin structure infections (ATLAS) trials, which demonstrated non-inferiority of telavancin to vancomycin. METHODS: We conducted a post hoc analysis of the ATLAS studies (ClinicalTrials.gov identifiers NCT00091819 and NCT00107978) to explore the efficacy of telavancin in patients with various types of cSSSIs. RESULTS: A total of 1794 patients were included in this analysis; 1434 patients were clinically evaluable (CE) and 563 of these had methicillin-resistant Staphylococcus aureus (MRSA). Among CE patients with major abscesses (n = 619), cure rates were 91% for telavancin and 90% for vancomycin (95% CI for the difference -3.6 to 5.7). In patients with infective cellulitis (n = 519), cure was achieved in 87% and 88% of telavancin- and vancomycin-treated patients, respectively (95% CI for the difference -6.2 to 5.2). Cure rates in patients with wound infections were 85% in the telavancin group and 86% in the vancomycin group (95% CI for the difference -10.5 to 9.0). Cure rates for each type of cSSSI in patients infected with MRSA were also similar between the two treatment arms. Among CE patients infected with Panton-Valentine leucocidin (PVL)-positive MRSA (n = 447), cure rates were 93% for telavancin and 90% for vancomycin (95% CI for the difference -2.2 to 8.2). CONCLUSIONS: Cure rates were similar for telavancin and vancomycin in patients with different types of cSSSIs, including infections caused by MRSA and PVL-positive strains of MRSA.

RESUMO

INTRODUCTION: The clinical spectrum of primary hyperparathyroidism (PHPT) has undergone a striking change with asymptomatic form predominant in developed countries, whereas symptomatic form predominant in developing countries. In this study, we have analyzed clinical presentation, investigations, management, operative findings in patients with PHPT at our center. MATERIALS AND METHOD: A retrospective, review of medical records of all patients with PHPT between 2000 and July 2012 at our institute was undertaken. A total of 96 patients were included in this study. RESULTS: The mean age of patients was 50.8 years. Of the 96 patients, 63 were females (65.6%) and 33 were males (34.4%). Among them, 17.7% were asymptomatic and 82.3% were symptomatic. Bone pain was the most common complaint (52%) followed by renal stones (27%). Nearly 10.4% were part of familial PHPT, whereas others were sporadic adenomas. All patients had hypercalcemia (range 10.5-19.4 mg/dl) with elevated parathyroid (PTH) levels (range 32-3820 pg/ml). 25(OH) VitD levels were available in 86 patients (89.6%). There was no correlation between VitaminD levels and symptomatology. Sestamibi scan was true positive in 95.6%, false negative 2.2%, and inconclusive in 2.2%. Ultrasonography (USG) results were true positive in 84.2%, false positive in 6.3%, and false negative in 9.5%. Intraoperative PTH levels were measured in 83.3% patients. Postoperative complications were reported in 20.8% patients. CONCLUSIONS: Clinical spectrum of PHPT varies but bones and stones are still the predominant manifestations even in affluent society. Asymptomatic form also exists and can be detected by routine measurement of serum calcium. There was no correlation seen between the 25 VitD levels and clinical symptoms.

RESUMO

BACKGROUND: Identifying the DNA binding sites for transcription factors is a key task in modeling the gene regulatory network of a cell. Predicting DNA binding sites computationally suffers from high false positives and false negatives due to various contributing factors, including the inaccurate models for transcription factor specificity. One source of inaccuracy in the specificity models is the assumption of asymmetry for symmetric models. METHODOLOGY/PRINCIPAL FINDINGS: Using simulation studies, so that the correct binding site model is known and various parameters of the process can be systematically controlled, we test different motif finding algorithms on both symmetric and asymmetric binding site data. We show that if the true binding site is asymmetric the results are unambiguous and the asymmetric model is clearly superior to the symmetric model. But if the true binding specificity is symmetric commonly used methods can infer, incorrectly, that the motif is asymmetric. The resulting inaccurate motifs lead to lower sensitivity and specificity than would the correct, symmetric models. We also show how the correct model can be obtained by the use of appropriate measures of statistical significance. CONCLUSIONS/SIGNIFICANCE: This study demonstrates that the most commonly used motif-finding approaches usually model symmetric motifs incorrectly, which leads to higher than necessary false prediction errors. It also demonstrates how alternative motif-finding methods can correct the problem, providing more accurate motif models and reducing the errors. Furthermore, it provides criteria for determining whether a symmetric or asymmetric model is the most appropriate for any experimental dataset.

RESUMO

Oritavancin is a novel lipoglycopeptide with demonstrated effectiveness against complicated skin and skin structure infections (cSSSI) caused by Gram-positive pathogens, including those caused by methicillin-resistant Staphylococcus aureus (MRSA). The pharmacokinetic and pharmacodynamic profile of oritavancin is favorable for single or infrequent dosing. A phase 2, multicenter, randomized, double-blind, parallel, active-comparator study (ClinicalTrials.gov identifier, NCT00514527) of single and infrequent dosing of intravenous (i.v.) oritavancin for the treatment of cSSSI caused by Gram-positive pathogens (wound infections, major abscess, and cellulitis) was undertaken to evaluate the noninferiority of front-loaded dosing regimens compared to a daily-dosing regimen. A total of 302 patients ≥ 18 years of age were randomized equally to one of three oritavancin treatment groups, receiving either a daily dose (200 mg) administered for 3 to 7 days, a single dose (1,200 mg), or an infrequent dose (800-mg dose, with the option for an additional 400 mg on day 5). The primary efficacy was defined as a clinical response in clinically evaluable (CE) patients assessed at days 21 to 29 (test of cure [TOC]). The cure rates in the CE population were 72.4% (55/76) in the daily-dose group, 81.5% (66/81) in the 1,200-mg-single-dose group, and 77.5% (55/71) in the infrequent-dose group. In patients with MRSA at baseline, the cure rates were 78.3% (18/23), 73.0% (27/37), and 87.0% (20/23) in the daily-, 1,200-mg-single-, and infrequent-dose groups, respectively; however, the study was not powered to assess outcomes in the MRSA subpopulation, and given the heterogeneity of the types of infection and the small sample size, these do not suggest any true differences in efficacy rates for these pathogens. The frequencies of adverse events were similar among treatment groups. The results of this study show that single- and infrequent-dosing schedules of oritavancin were as efficacious as daily administration and had a similar safety profile in treating cSSSI caused by Gram-positive pathogens, including MRSA.

RESUMO

Telavancin is a novel antibiotic being investigated for the treatment of serious infections caused by Gram-positive bacteria, including complicated skin and skin structure infections (cSSSI) and pneumonia. This once-daily intravenous lipoglycopeptide exerts rapid bactericidal activity via a dual mechanism of action. It is intended for use to combat infections caused by Staphylococcus aureus and other Gram-positive bacteria, including methicillin-resistant and vancomycin-intermediate strains of S. aureus (MRSA and VISA, respectively). Vancomycin is the current gold standard in treating serious infections caused by Gram-positive bacteria, especially MRSA. In recent clinical trials, telavancin has shown excellent efficacy in phase II and III multinational, randomized, double-blinded studies of cSSSI. In the phase II FAST 2 study, which compared telavancin 10 mg/kg intravenously q 24 h vs standard therapy (an antistaphylococcal penicillin at 2 g IV q 6 h or vancomycin 1 gm IV q 12 h), the clinical success rate in the telavancin-treated group was 96% vs 94% in the standard therapy group. In two identical phase III trials comparing telavancin versus vancomycin at the doses of the FAST 2 study for cSSSI, the clinical cure rates were 88.3% and 87.1%, respectively. Two additional phase III clinical trials investigating telavancin for use in hospital-acquired pneumonia, caused by Gram-positive bacteria are currently ongoing. Telavancin is currently under regulatory review in both the United States and Europe for the indication of treatment of cSSSI.

RESUMO

Telavancin is a bactericidal lipoglycopeptide with a multifunctional mechanism of action. We conducted a randomized, double blind, active-control phase II trial. Patients > or = 18 years of age with complicated skin and skin structure infections caused by suspected or confirmed gram-positive organisms were randomized to receive either telavancin at 10 mg/kg intravenously every 24 h (q24h) or standard therapy (antistaphylococcal penicillin at 2 g q6h or vancomycin at 1 g q12h). A total of 195 patients were randomized and received at least one dose of study medication. Clinical success rates were similar in all analysis populations at test of cure. In microbiologically evaluable patients with Staphylococcus aureus at baseline (n = 91), 96% of the telavancin group and 90% of the standard-therapy group were cured. Among patients with methicillin-resistant S. aureus (MRSA) at baseline (n = 45), clinical cure rates were also 96% for telavancin and 90% for standard therapy. Microbiologic eradication in patients with S. aureus infection was better with telavancin compared to standard therapy (92% versus 78%, P = 0.07) and significantly better in patients with MRSA (92% versus 68%; P = 0.04). Therapy was discontinued for an adverse event (AE) in 6% and 3% of the patients receiving telavancin and standard therapy, respectively. Except for two cases of rash in the telavancin group, these AEs were similar in type and severity in the two groups. The overall incidences and severities of AEs and laboratory abnormalities were similar between the two groups. These data support the ongoing studies assessing the efficacy and safety of telavancin in the treatment of serious gram-positive infections, particularly involving MRSA.

RESUMO

BACKGROUND: Community-acquired pneumonia (CAP) remains a major cause of morbidity and mortality throughout the world. Telithromycin (a new ketolide) has shown good in vitro activity against the key causative pathogens of CAP, including S pneumoniae resistant to penicillin and/or macrolides. METHODS: The efficacy and safety of telithromycin 800 mg orally once daily for 7 days in the treatment of CAP were assessed in an open-label, multicenter study of 442 adults. RESULTS: Of 149 microbiologically evaluable patients, 57 (9 bacteremic) had Streptococcus pneumoniae. Of the 57 S pneumoniae pathogens isolated in these patients, 9 (2 bacteremic) were penicillin- or erythromycin-resistant; all 57 were susceptible to telithromycin and were eradicated. Other pathogens and their eradication rates were: Haemophilus influenzae (96%), Moraxella catarrhalis (100%), Staphylococcus aureus (80%), and Legionella spp. (100%). The overall bacteriologic eradication rate was 91.9%. Of the 357 clinically evaluable patients, clinical cure was achieved in 332 (93%). In the 430 patients evaluable for safety, the most common drug-related adverse events were diarrhea (8.1%) and nausea (5.8%). CONCLUSION: Telithromycin 800 mg once daily for 7 days is an effective and well-tolerated oral monotherapy and offers a new treatment option for CAP patients, including those with resistant S pneumoniae.

RESUMO

BACKGROUND: Telavancin, a novel lipoglycopeptide, exerts concentration-dependent, rapid bactericidal activity on account of its multiple mechanisms of action. Telavancin is highly active against gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-intermediate, and vancomycin-resistant strains. METHODS: We conducted a randomized, double-blind, controlled, phase-2 clinical trial. Patients > or = 18 years of age with a diagnosis of complicated skin and soft-tissue infection caused by suspected or confirmed gram-positive organisms were randomized to receive either intravenously administered telavancin once daily or standard therapy (antistaphylococcal penicillin 4 times daily or vancomycin twice daily). RESULTS: For the study, 167 patients were randomized and received at least 1 dose of study medication. Success rates were similar in all analysis populations at the test-of-cure evaluation. Of patients with S. aureus infection at baseline (n = 102), 80% of the telavancin group were cured and 77% of the standard therapy group were cured. For patients with MRSA infection at baseline (n = 48), cure rates were 82% for the telavancin group and 69% for the standard therapy group. Microbiologic eradication in patients with MRSA infection was 84% for the telavancin group versus 74% for the standard therapy group. MIC90 values were lower for telavancin in all tested strains of S. aureus (< or = 0.25 ug/mL) compared with the MIC90 values for vancomycin and oxacillin. Similar proportions of patients discontinued therapy for adverse events in both treatment groups (approximately 5%). Fewer serious adverse events were reported in the telavancin group (4 events) than were for the standard therapy group (9). CONCLUSION: Clinical and microbiological results of this study support the further development of telavancin, especially for treatment of infection due to MRSA.

RESUMO

BACKGROUND: Current recommended durations for treatment of atypical community-acquired pneumonia (CAP) range from 10 to 21 days. However, antibiotics such as the fluoroquinolones may allow for effective, short-course regimens. OBJECTIVE: This study evaluated the efficacy of 750 mg levofloxacin for 5 days compared to a 500-mg, 10-day levofloxacin regimen for the treatment of atypical CAP. METHODS: A randomized, active-controlled, double-blind, multicenter study was conducted within the United States. Of the 528 patients enrolled in the study, 149 were diagnosed with CAP due to Legionella pneumophila, Chlamydia pneumoniae, or Mycoplasma pneumoniae. Patients' baseline symptoms were re-evaluated on Day 3 of therapy. Clinical efficacy and resolution of CAP symptoms were evaluated at the posttherapy visit (7-14 days after the last dose of active drug). RESULTS: This report represents a subgroup analysis of a previous clinical study. Among the 123 clinically evaluable patients diagnosed with atypical CAP (26 patients were unevaluable), the clinical success rates were 95.5% (63 of 66 patients) for the 750-mg group and 96.5% (55 of 57 patients) for the 500-mg group (95% CI for success rate of the 500-mg group minus that of the 750-mg group, -6.8 to 8.8). At the poststudy evaluation (31-38 days after treatment began), relapse occurred in

RESUMO

STUDY OBJECTIVE: We determine tetanus seroprotection rates and physician compliance with tetanus prophylaxis recommendations among patients presenting with wounds. METHODS: A prospective observational study of patients aged 18 years or older who presented to 5 university-affiliated emergency departments (EDs) because of wounds was conducted between March 1999 and August 2000. Serum antitoxin levels were measured by enzyme immunoassay with seroprotection defined as more than 0.15 IU/mL. Seroprotection rates, risk factors for lack of seroprotection, and rates of physician compliance with tetanus prophylaxis recommendations by the Advisory Committee on Immunization Practices were determined. RESULTS: The seroprotection rate among 1,988 patients was 90.2% (95% confidence interval 88.8% to 91.5%). Groups with significantly lower seroprotection rates were persons aged 70 years or older, 59.5% (risk ratio [RR] 5.2); immigrants from outside North America or Western Europe, 75.3% (RR 3.7); persons with a history of inadequate immunization, 86.3% (RR 2.9); and persons without education beyond grade school, 76.5% (RR 2.5). Despite a history of adequate immunization, 18% of immigrants lacked seroprotection. Overall, 60.9% of patients required tetanus immunization, of whom 57.6% did not receive indicated immunization. Among patients with tetanus-prone wounds, appropriate prophylaxis (ie, tetanus immunoglobulin and toxoid) was provided to none of 504 patients who gave a history of inadequate primary immunization (of whom 15.1% had nonprotective antibody titers) and to 218 (79%) of 276 patients who required only a toxoid booster. CONCLUSION: Although seroprotection rates are generally high in the United States, the risk of tetanus persists in the elderly, immigrants, and persons without education beyond grade school. There is substantial underimmunization in the ED (particularly with regard to use of tetanus immunoglobulin), leaving many patients, especially those from high-risk groups, unprotected. Better awareness of tetanus prophylaxis recommendations is necessary, and future tetanus prophylaxis recommendations may be more effective if they are also based on demographic risk factors.

RESUMO

The worldwide burden of respiratory tract disease is enormous. Resistance to penicillins, macrolides, and cephalosporins is now detected among the leading bacterial pathogens that cause respiratory tract infections (RTIs)-Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. The increasing role of atypical/intracellular pathogens (eg, Chlamydia pneumoniae, Mycoplasma pneumoniae, Legionella pneumophila) in RTIs, as well as their increase in antibiotic resistance prevalence, continues to be of great concern. More recently introduced treatment options for RTIs include the newer respiratory fluoroquinolones, along with the macrolides and azalides. Although these agents demonstrate good activity against common respiratory pathogens, reduced susceptibility to these agents has been reported. The ketolides are recently developed antibacterial agents with targeted-spectrum activity against common respiratory tract pathogens, including atypical/intracellular pathogens, and a low potential for inducing resistance. These promising new drugs have shown in vitro and in vivo efficacy in the treatment of community-acquired RTIs, such as community-acquired pneumonia, acute exacerbations of chronic bronchitis, and acute bacterial maxillary sinusitis.

RESUMO

Levofloxacin demonstrates concentration-dependent bactericidal activity most closely related to the pharmacodynamic parameters of the ratio of area under the concentration-time curve (AUC) to minimum inhibitory concentration (MIC) and the ratio of peak plasma concentration (C(max)) to MIC. Increasing the dose of levofloxacin to 750 mg exploits these parameters by increasing peak drug concentrations, allowing for a shorter course of treatment without diminishing therapeutic benefit. This was demonstrated in a multicenter, randomized, double-blind investigation that compared levofloxacin dosages of 750 mg per day for 5 days with 500 mg per day for 10 days for the treatment of mild to severe community-acquired pneumonia (CAP). In the clinically evaluable population, the clinical success rates were 92.4% (183 of 198 persons) for the 750-mg group and 91.1% (175 of 192 persons) for the 500-mg group (95% confidence interval, -7.0 to 4.4). Microbiologic eradication rates were 93.2% and 92.4% in the 750-mg and 500-mg groups, respectively. These data demonstrate that 750 mg of levofloxacin per day for 5 days is at least as effective as 500 mg per day for 10 days for treatment of mild-to-severe CAP.

RESUMO

Children below 15 yrs. of age without BCG scar were chosen for the tuberculin testing. Total 210 children were tested in 30 selected clusters (7 children in each cluster). Median age of the surveyed children was 6.33. Prevalence of infection in children was found to be 30.4% as 64 children out of 210 showed positive result (had induration > or = 10mm in size). Average ARI in the 0-14 yrs of age group was 5.4%. Tuberculosis is still one of the commonest problems in the urban slums. It is important to evaluate the epidemiology of tuberculosis in the changing face of century.
