RESUMO
Retrospective observational study. To determine the efficacy and safety of bioactive glass ceramics mixed with autograft in the treatment of spondylodiscitis. Thirty-four patients with spondylodiscitis underwent surgery using autologous bone graft augmented by antibiotic loaded bioactive glass ceramic granules. Twenty-five patients aging 6 to 77, completed 1-year follow-up. The lumbosacral junction was affected in 3, lumbar spine in 13, one each in the dorso-lumbar junction and sacrum, and 7 dorsal spines. The organism isolated was Mycobacterium tuberculosis in 15, Methicillin sensitive Staphylococcus aureus (MSSA) in 4, Pseudomonas aeruginosa in 4, Klebsiella pneumoniae in one, Burkholderia pseudomallei in 1, and mixed infections in 2. All patients had appropriate antibiotic therapy based on culture and sensitivity. Clinical and radiological evaluation of all the patients was done at 6 weeks, 3 months, 6 months, and 12 months after the surgery. Twenty-three patients improved clinically and showed radiographic fusion between 6 and 9 months. The patient with Burkholderia infection died due to fulminant septicemia with multi organ failure while another patient died at 9 months due to an unrelated cardiac event. The mean Visual Analogue Score (VAS) at the end of 1-year was 2 with radiological evidence of fusion in all patients. There were no re-infections or discharging wounds, and the 30-day re-admission rate was 0. Bioactive glass ceramics is a safe and effective graft expander in cases of spondylodiscitis. The absorption of antibiotics into the ceramic appears to help the elimination of infection.

The rapidly increasing burden of hypertension is responsible for premature deaths from cardiovascular disease (CVD), renal disease, and stroke, with a tremendous public health and financial burden. Hypertension detection, treatment, and control vary worldwide; it is still low, particularly in low- and middle-income countries (LMICs). High blood pressure (BP) and CVD risk have a strong, linear, and independent association. They contribute to alarming numbers of all-cause and CVD deaths. A major culprit for increased hypertension is sympathetic activity, and further complications of hypertension are heart failure, ischemic heart disease (IHD), stroke, and renal failure. Now, antihypertensive interventions have emerged as a global public health priority to reduce BP-related morbidity and mortality. Calcium channel blockers (CCB) are highly effective vasodilators. and the most common drugs used for managing hypertension and CVD. Cilnidipine, with both L- and N-type calcium channel blocking activity, is a promising 4th generation CCB. It causes vasodilation via L-type calcium channel blockade and inhibits the sympathetic nervous system (SNS) via N-type calcium channel blockade. Cilnidipine, which acts as a dual L/N-type CCB, is linked to a reduced occurrence of pedal edema compared to amlodipine, which solely blocks L-type calcium channels. The antihypertensive properties of cilnidipine are very substantial, with low BP variability and long-acting properties. It is beneficial for hypertensive patients to deal with morning hypertension and for patients with abnormal nocturnal BP due to exaggerated sympathetic nerve activation. Besides its BP-lowering effect, it also exhibits organ protection via sympathetic nerve inhibition and renin-angiotensin-aldosterone system inhibition; it controls heart rate and proteinuria. Reno-protective, neuroprotective, and cardioprotective effects of cilnidipine have been well-documented and demonstrated.

Adverse cardiac remodeling refers to progressive structural and functional modifications in the heart because of increased wall stress in the myocardium, loss of viable myocardium, and neurohormonal stimulation. The guideline-directed medical therapy for Heart failure (HF) includes Angiotensin receptor-neprilysin inhibitor (ARNI) (sacubitril/valsartan), ß-blockers, sodium-glucose co-transporter 2 (SGLT2) inhibitors, and mineralocorticoid receptor antagonists (MRA). ARNI is under-prescribed in India despite its attractive safety and efficacy profile. Therefore, the consensus discusses objectives and topics related to ARNI in the management of cardiac remodeling, and experts shared their views on the early timely intervention of effective dosage of ARNI to improve the diagnosis and enhance mortality and morbidity benefits in cardiac reverse remodeling (CRR).

;Heart failure (HF) is a huge global public health task due to morbidity, mortality, disturbed quality of life, and major economic burden. It is an area of active research and newer treatment strategies are evolving. Recently angiotensin receptor-neprilysin inhibitor (ARNI), a class of drugs (the first agent in this class, Sacubitril-Valsartan), reduces cardiovascular mortality and morbidity in chronic HF patients with reduced left ventricular ejection fraction (LVEF). Positive therapeutic effects have led to a decrease in cardiovascular mortality and HF hospitalizations (HFH), with a favorable safety profile, and have been documented in several clinical studies with an unquestionable survival benefit with ARNI, Sacubitril-Valsartan. This consensus statement of the Indian group of experts in cardiology, nephrology, and diabetes provides a comprehensive review of the power and promise of ARNI in HF management and an evidence-based appraisal of the use of ARNI as an essential treatment strategy for HF patients in clinical practice. Consensus in this review favors an early utility of Sacubitril-Valsartan in patients with HF with reduced EF (HFrEF), regardless of the previous therapy being given. A lower rate of hospitalizations for HF with Sacubitril-Valsartan in HF patients with preserved EF who are phenotypically heterogeneous suggests possible benefits of ARNI in patients having 40-50% of LVEF, frequent subtle systolic dysfunction, and higher hospitalization risk.

Iron deficiency (ID) with or without anemia is frequently observed in patients with heart failure (HF). Uncorrected ID is associated with higher hospitalization and mortality in patients with acute HF (AHF) and chronic HF (CHF). Hence, in addition to chronic renal insufficiency, anemia, and diabetes, ID appears as a novel comorbidity and a treatment target of CHF. Intravenous (IV) ferric carboxymaltose (FCM) reduces the hospitalization risk due to HF worsening and improves functional capacity and quality of life (QOL) in HF patients. The current consensus document provides criteria, an expert opinion on the diagnosis of ID in HF, patient profiles for IV FCM, and correct administration and monitoring of such patients.

PURPOSE: The present study made an attempt to develop copper nanoparticles (Cu-NP) with antifungal property using green synthesis method. Copper oxide nanoparticles (CuO-NPs) botanically synthesized using Neem leaf extract (Azadirachta indica A. Juss) were characterized by using different techniques like; UV-visible spectrophotometry, FTIR, XRD, SEM and TEM. METHODS: Materials were chosen the disease free and fresh Azadirachta indica A. Juss were collected and identified at Center of Biodiversity and Taxonomy. The plant samples were vigorously washed with distilled water then shade dried followed by sterilization with 0.1% mercuric chloride for 20 s and again it was washed with distilled water. 15 g powder form of plant material was added to 200 ml double distilled, CO2 free and deionized water and kept in shaker at 80°C and 1500 rpm for six hours. After agitation, the extract was separated by regular centrifugation at 10,000 rpm followed by filtration by using whatmann filter paper. The final volume of 100 ml of supernatant was collected as pure extract and stored in cool place for further use. RESULTS: The final results confirm a significant inhibition of CuO-NPs for the test fungi. Additionally, CuO-NPs demonstrated an enhanced effect when combined with Neem leaf extract. A total of 20-30% improvement in activity was noticed after combination, which correlates with commonly used synthetic fungicides. The toxicity results reveal that A. indica extract and their combined fractions with CuO-NP were less toxic to the test seeds of experimental plant while as bulk Cu followed by biosynthesized CuO-NPs influenced the germination rate as compared to control pots. CONCLUSIONS: The study drops a concern of research and offers a promising route of developing Copper based green fungicides that can help to combat with modern issues of synthetic fungicides. An average size of 80 ± 15 nm monoclinic cupric oxide (CuO) and cubic cuprous oxides (Cu2O) nanocrystals that existed in mixed form were successfully developed.

BACKGROUND: Notching of the anterior femoral cortex during total knee arthroplasty (TKA) has been attributed to cause supracondylar fractures of the femur. Anatomic variations in the femur bone in different races make notching inevitable when standard designs of prostheses are used. The objective of this study is to determine the prevalence of notching when a PFC Sigma knee was used in an Indian population sample using the anterior referencing system and to assess the frequency of femoral shaft fractures in these cases. METHODS: This is a single-center, prospective study. All patients undergoing TKA were recruited and followed up for a minimum of 2 years. All patients had a PFC Sigma knee (DePuy Synthes), and the anterior referencing system was used for implantation. The Knee Society Score was used for outcome scoring and the Gujarathi's schema for the grading of notching. Radiological outcomes were evaluated by an independent observer. Linear regression analysis assessed the effect of notching on range of motion and final score. RESULTS: Of the 200 cases, 21% had varying degrees of notching. Grade I was seen in 13%, grade II in 6.5%, grade III in 1%, and grade IV in 0.5% in this series. There was no supracondylar fracture in 2 years. Notching had no bearing on the range of movement or outcome scores. CONCLUSION: Although notching is best avoided, this study has shown no correlation between notching and supracondylar fracture of the femur following TKA. It does not appear to have any bearing on the range of movement or final outcome scores.

BACKGROUND: Clinical as well as subclinical hyponatremia is frequently seen after orthopedic surgery. The study was aimed to determine the frequency and severity of hyponatremia in a cohort of total joint arthroplasty cases and identify the risk factors and their impact. METHODS: This is a retrospective observational study of 546 consecutive cases of total joint arthroplasty patients from a single institution. Only primary hip and knee replacements were included. The study was approved by the institutional review board. Preoperative and postoperative serum electrolytes were recorded till 45-day review. This was correlated with the age, gender, BMI, drug intake, and comorbidities. RESULTS: We identified 84.9% postsurgical hyponatremia in our cohort. Of these 80% were mild, 16% moderate and 4% severe. Preoperative hyponatremia was a consistent finding in most severe cases. Thaizides, ACE inhibitors, and longer surgeries like bilateral TKRs had more hyponatremia. Hospital stay was not impacted in this study for reasons discussed. There were no deaths in this series during the follow-up period, but two patients were rehospitalized. CONCLUSION: Postsurgical hyponatremia occurs in up to 85% of primary hip and knee arthroplasty patients. The most consistent predictor of severe electrolyte disturbance postsurgery is preoperative hyponatremia. Older age, female gender, longer surgery, and drugs like thiazides and ACE inhibitors seemed contributory.

Could some vaccines drive the evolution of more virulent pathogens? Conventional wisdom is that natural selection will remove highly lethal pathogens if host death greatly reduces transmission. Vaccines that keep hosts alive but still allow transmission could thus allow very virulent strains to circulate in a population. Here we show experimentally that immunization of chickens against Marek's disease virus enhances the fitness of more virulent strains, making it possible for hyperpathogenic strains to transmit. Immunity elicited by direct vaccination or by maternal vaccination prolongs host survival but does not prevent infection, viral replication or transmission, thus extending the infectious periods of strains otherwise too lethal to persist. Our data show that anti-disease vaccines that do not prevent transmission can create conditions that promote the emergence of pathogen strains that cause more severe disease in unvaccinated hosts.

Avian influenza is a significant economic burden on the poultry industry in geographical regions where it is enzootic. It also poses a public health concern when avian influenza subtypes infect humans, often with high mortality. Understanding viral genetic factors which positively contribute to influenza A virus (IAV) fitness - infectivity, spread and pathogenesis - is of great importance both for human and livestock health. PB1-F2 is a small accessory protein encoded by IAV and in mammalian hosts has been implicated in a wide range of functions that contribute to increased pathogenesis. In the avian host, the protein has been understudied despite high-level full-length conservation in avian IAV isolates, which is in contrast to the truncations of the PB1-F2 length frequently found in mammalian host isolates. Here we report that the presence of a full-length PB1-F2 protein, from a low pathogenicity H9N2 avian influenza virus, prolongs infectious virus shedding from directly inoculated chickens, thereby enhancing transmission of the virus by lengthening the transmission window to contact birds. As well as extending transmission, the presence of a full-length PB1-F2 suppresses pathogenicity evidenced by an increased minimum lethal dose in embryonated chicken eggs and increasing survival in directly infected birds when compared to a virus lacking an ORF for PB1-F2. We propose that there is a positive pressure to maintain a full-length functional PB1-F2 protein upon infection of avian hosts as it contributes to the effective transmission of IAV in the field.

BACKGROUND: There are no recent data on prevalence of coronary artery disease (CAD) in Indians. The last community based study from Kerala, the most advanced Indian state in epidemiological transition, was in 1993 that reported 1.4% definite CAD prevalence. We studied the prevalence of CAD and its risk factors among adults in Kerala. METHODS: In a community-based cross sectional study, we selected 5167 adults (mean age 51 years, men 40.1%) using a multistage cluster sampling method. Information on socio-demographics, smoking, alcohol use, physical activity, dietary habits and personal history of hypertension, diabetes, and CAD was collected using a structured interview schedule. Anthropometry, blood pressure, electrocardiogram, and biochemical investigations were done using standard protocols. CAD and its risk factors were defined using standard criteria. Comparisons of age adjusted prevalence were done using two tailed proportion tests. RESULTS: The overall age-adjusted prevalence of definite CAD was 3.5%: men 4.8%, women 2.6% (p < 0.001). Prevalence of any CAD was 12.5%: men 9.8%, women 14.3% (p < 0.001). There was no difference in definite CAD between urban and rural population. Physical inactivity was reported by 17.5 and 18% reported family history of CAD. Other CAD risk factors detected in the study were: overweight or obese 59%, abdominal obesity 57%, hypertension 28%, diabetes 15%, high total cholesterol 52% and low level of high density lipoprotein cholesterol 39%. Current smoking was reported only be men (28%). CONCLUSION: The prevalence of definite CAD in Kerala increased nearly three times since 1993 without any difference in urban and rural areas. Most risk factors of CAD were highly prevalent in the state. Both population and individual level approaches are warranted to address the high level of CAD risk factors to reduce the increasing prevalence of CAD in this population.

Wine was prepared from three varieties of Phyllanthus viz., P. emblica (wild and cultivated) and P. acidus. Among the wines prepared, cultivated Emblica wine had the highest total phenolic (11.02 µg gallic acid equivalent/ml) and flavonoid (59.46 µg quercetin equivalent/ml) content. Further gallic acid, syringic acid, protocatechuic acid and caffeic acid were present in higher amounts in wine from the cultivated variety compared to other wines. HPLC analysis showed that in juice of the cultivated variety, gallic acid and coumaric acid were found in higher amounts than that in the corresponding wine. Antioxidant assays, LDL oxidation prevention, foam cell prevention and nitrite scavenging activities (cell lines) were found to be highest in cultivated Emblica juice and wine with an activity of 15 µg/ml and 14 µg/ml (nitrite assay) and 108.649 µg ascorbic acid equivalent/mg and 321.622 µg ascorbic acid equivalent /mg (total antioxidant capacity) respectively. CD36 expression was reduced and ABCA1 expression was increased to the highest extent by the cultivated Emblica wine and juice. Further, antioxidant activity was seen to increase during the course of fermentation. Sensory analysis showed that cultivated Emblica wine was sweeter compared to the other wines.
RESUMO
Glycogenic hepatopathy (GH) is an under-recognised complication of type 1 diabetes mellitus (T1DM) not controlled to target resulting in hepatomegaly and elevated liver transaminases. We report the case of a 19-year-old man with T1DM not controlled to target who presented with abdominal pain, hepatomegaly and deranged liver transaminases. He was subsequently diagnosed with GH on liver biopsy, with the mainstay of treatment being reduction in caloric intake and insulin.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: The aim of this study was to identify morphologic features on magnetic resonance imaging that might correlate with lumbar canal stenosis severe enough to warrant surgery. SUMMARY OF BACKGROUND DATA: None of the quantitative parameters measured on x-rays, CT scans, or magnetic resonance imaging correlates well with the severity of clinical symptoms in lumbar canal stenosis (LCS). In a patient with neurogenic claudication, we need to define what would constitute radiologic LCS and whether he needs surgical intervention. This paper attempts to define MRI features of LCS addressing the morphology rather than canal dimensions in any direction. MATERIALS AND METHODS: A total of 64 consecutive patients who were operated at 113 levels of LCS were reviewed retrospectively. Their clinical notes and MRI were analyzed. Only the axial T2-weighted images were utilized for this study. The images were reviewed by 1 orthopedic surgeon and 1 radiologist and segregated into morphologic categories. No interobserver and intraobserver studies were undertaken. RESULTS: Two types of axial image features were identified in LCS symmetrical and asymmetrical with 5 subtypes. They were trefoil, triangular, "cat's eye," "pinhole," and complete obliteration. Several subtypes were also described. Of the operated cases, 70.8% had a triangular configuration of the canal with symmetrical large triangular canal shape occurring in 49/80 levels. It was impossible to correlate the severity of symptoms, their duration, and the presence of objective neurological deficits with the morphologic picture from the documentation available. CONCLUSIONS: LCS seems to produce predictable patterns on T2 axial MRI. The triangular configuration correlates most frequently with surgical LCS. Further studies are needed in normal individuals, in prospective patients, and to determine the outcome of treatment based on MRI morphology.

Fipronil is a broadspectrum N-phenylpyrazole insecticide with gamma-aminobutyric acid type A receptor inhibitory action causing hyperexcitability of central nervous system. There is no literature reported in the past concerning its acute toxicity in human beings. A case report is useful for workers in medical and veterinary field. Hence, we are reporting a case in which young male intoxicated with fipronil compound was presented to the emergency department for having generalized tonic-clonic seizures and subsequently with the features of delirium for few days. This patient was treated with benzodiazepines which controlled the seizures and antipsychotics were given for few days for treating the psychosis.
RESUMO
Ancient endogenous retroviruses (ERVs), designated endogenous avian retrovirus (EAVs), are present in all Gallus spp. including the chicken, and resemble the modern avian sarcoma and leukosis viruses (ASLVs). The EAVs comprise several distinct retroviruses, including EAV-0, EAV-E51 and EAV-HP, as well as a putative member previously named the avian retrotransposon of chickens (ART-CH). Thus far, only the EAV-HP elements have been well characterized. Here, we determined sequences of representative EAV-0 and EAV-E51 proviruses by cloning and data mining of the 2011 assembly of the Gallus gallus genome. Although the EAV-0 elements are primarily deleted in the env region, we identified two complete EAV-0 env genes within the G. gallus genome and prototype elements sharing identity with an EAV-E51-related clone previously designated EAV-E33. Prototype EAV-0, EAV-E51 and EAV-E33 gag, pol and env gene sequences used for phylogenetic analysis of deduced proteins showed that the EAVs formed three distinct clades, with EAV-0 sharing the last common ancestor with the ASLVs. The EAV-E51 clade showed the greatest level of divergence compared with other EAVs or ASLVs, suggesting that these ERVs represented exogenous retroviruses that evolved and integrated into the germline over a long period of time. Moreover, the degree of divergence between the chicken and red jungle fowl EAV-E51 sequences suggested that they were more ancient than the other EAVs and may have diverged through mutations that accumulated post-integration. Finally, we showed that the ART-CH elements were chimeric defective ERVs comprising portions of EAV-E51 and EAV-HP rather than authentic retrotransposons.

Pheniramine maleate is an easily accessible, over-the-counterantihistaminic, which is frequently involved in overdoses. Pheniramine has antimuscarinic effect causing tachycardia, dilated pupils, urinary retention, and dry flushed skin, and decreased bowel sounds, confusion, mild increase in body temperature, cardiac arrhythmias, and seizures at lethal doses. It has not been implicated as an important cause of rhabdomyolysis and acute kidney injury (AKI). Rhabdomyolysis causing AKI is rarely reported in the literature. This case report emphasizes the occurrence of nontraumatic rhabdomyolysis in pheniramine maleate overdose which required hemodialysis. Since there is a lack of a specific antidote, treatment is mainly symptomatic and supportive. We report a fatal case of a young male with a very high dose of consumption of pheniramine maleate (4.077 g), which was complicated by seizures, respiratory depression, nontraumatic rhabdomyolysis, and AKI. Despite hemodialysis, ventilator support, and other intensive supportive care, patient could not survive and death ensued due to multiorgan dysfunction syndrome.
RESUMO
To assess the effect of various vaccine strains on replication and shedding of virulent Marek's disease virus from experimentally infected chickens, quantitative PCR (q-PCR) methods were developed to accurately quantify viral DNA in infected chickens and in the environment in which they were housed. Four groups of 10 chickens, kept in poultry isolators, were vaccinated at 1 day old with one of four vaccines covering each of the three vaccine serotypes, then challenged with very virulent MDV strain Md5 at 8 days of age. At regular time-points, feather tips were collected from each chicken and poultry dust was collected from the air-extract prefilter of each isolator. DNA was extracted from feather and dust samples and subjected to real-time q-PCR, targeting the U(S)2 gene of MDV-1, in order to measure Md5 level per 10(4) feather tip cells or per microgram of dust. Accuracy of DNA extraction from dust and real-time q-PCR were validated by comparing either q-PCR cycle threshold values or the calculated MDV genome level; for use in q-PCR, DNA was extracted from serial dilutions of MDV-infected dust diluted with noninfected dust, or DNA from MDV-infected dust was diluted with DNA from noninfected dust. The results confirmed the accuracy and sensitivity of dust DNA extraction and subsequent q-PCR and showed that differences in virus levels between dust samples truly reflect differences in shedding. Vaccination delayed both replication of Md5 in feather tips and shedding of Md5. First detection of Md5 in feather tips always preceded or coincided with first detection in dust in each group. pCVI988 and HVT+SB-1 were the most efficient vaccines in reducing both replication and shedding of Md5. There was close correlation between mean virus level in feathers of each group and mean virus level in the dust shed by that group. This relationship was similar in each of the vaccinated groups, demonstrating that measurement of the virus in dust can be used to monitor accurately both the infection status of the chickens and environmental contamination by MDV.

BACKGROUND: There is paucity of reliable contemporary data on prevalence of coronary artery disease (CAD) and risk factors in Indians. Only a few studies on prevalence of CAD have been conducted in Kerala, a Southern Indian state. The main objective of the Cardiological Society of India Kerala Chapter Coronary Artery Disease and Its Risk Factors Prevalence Study (CSI Kerala CRP Study) was to determine the prevalence of CAD and risk factors of CAD in men and women aged 20-79 years in urban and rural settings of three geographical areas of Kerala. METHODS: The design of the study was cross-sectional population survey. We estimated the sample size based on an anticipated prevalence of 7.4% of CAD for rural and 11% for urban Kerala. The derived sample sizes for rural and urban areas were 3000 and 2400, respectively. The urban areas for sampling constituted one ward each from three municipal corporations at different parts of the state. The rural sample was drawn from two panchayats each in the same districts as the urban sample. One adult from each household in the age group of 20-59 years was selected using Kish method. All subjects between 60 and 79 years were included from each household. A detailed questionnaire was administered to assess the risk factors, history of CAD, family history, educational status, socioeconomic status, dietary habits, physical activity and treatment for CAD; anthropometric measurements, blood pressure, electrocardiogram and fasting blood levels of glucose and lipids were recorded.

Introduction: Blunt trauma of the lower limb with vascular injury can cause devastating outcomes, including loss of limb and even loss of life. The primary aim of this study was to determine the limb salvage rate of patients sustaining such injuries when treated at Leeds General Infirmary (LGI) since becoming a Major Trauma Centre (MTC). The secondary aim was to establish patient complications. Methods: A retrospective analysis found that from 2013 to 2018, 30 patients, comprising of 32 injured limbs, were treated for blunt trauma to the lower limb associated with vascular injury. Results: Twenty-four patients were male and six were female. Their mean ages were 32 and 49, respectively. Three limbs were deemed unsalvageable and underwent primary amputation; of the remaining 29 potentially salvageable limbs, 27 (93%) were saved. Median ischaemic times for both amputees and salvaged limbs were under 6 hours. Of the 32 limbs, 27 (84%) were salvaged. All amputees had a MESS score ≥ 7, although not all patients with MESS ≥ 7 required amputation. Eleven limbs had prophylactic fasciotomies, three limbs developed compartment syndrome - all successfully treated and three contracted deep infections - one of which necessitated amputation. All but one patient survived their injuries and were discharged from the hospital. Conclusion: Attempted salvage of 27/29 (93%) limbs was successful and all but one patient survived these injuries when treated at an MTC. MESS scoring and ischaemic time are useful but not sole predictors of limb salvage. Complication rates are low but may be significant for their future implications.
