Abstract
BACKGROUND Patient knowledge about chronic diseases increases health-promoting behaviors and improves clinical outcomes. We assessed this association for patients with chronic viral hepatitis. METHODS Untreated patients chronically infected with HBV (n = 500) or HCV (n = 500) were enrolled at 19 centers across India. A survey, adapted from the US CDC National Health and Nutrition Examination Survey (NHANES) questionnaire, was administered at a single visit to assess HBV/HCV knowledge, community disease awareness, treatment quality, and healthcare barriers. We developed the India Hepatitis Knowledge Index (IHKI), where a higher IHKI score (range 0-10) indicates increased hepatitis knowledge. Multivariate regression models evaluated demographic and disease factors. RESULTS The overall mean IHKI score was 5.6 out of 10, with higher scores among patients with HBV (5.9) than HCV (5.3); p < 0.001. In HBV patients lower IHKI was associated with shorter disease duration, government clinic attendance (p < 0.0001), fewer personal experiences with HBV (p < 0.0001), and residing in northern India. Among HCV patients, lower IHKI was associated with shorter disease duration, community (p < 0.0001) and government clinic attendance (p < 0.0001), and fewer personal experiences with HCV (p < 0.0001). Among HBV patients, IHKI was independently associated with disease severity as assessed by MELD score, albumin, and APRI. This association was strongest for HBV patients with elevated ALT and HBV DNA >2000 IU/ml. Among HCV patients, IHKI results had no significant associations with disease severity. CONCLUSIONS The association of IHKI with disease underscores the need to understand connections between hepatitis knowledge and progression and may guide efforts to address patient education and awareness of chronic viral hepatitis in India.

Abstract
Severe injuries in the craniofacial complex, resulting from trauma or pathology, present several challenges to functional and aesthetic reconstruction. The anatomy and position of the craniofacial region make it vulnerable to injury and subsequent local infection due to external bacteria as well as those from neighbouring structures like the sinuses, nasal passages, and mouth. Porous polymethylmethacrylate (PMMA) "space maintainers" have proven useful in staged craniofacial reconstruction by promoting healing of overlying soft tissue prior to reconstruction of craniofacial bones. We describe herein a method by which the porosity of a prefabricated porous PMMA space maintainer, generated by porogen leaching, can be loaded with a thermogelling copolymer-based drug delivery system. Porogen leaching, space maintainer prewetting, and thermogel loading all significantly affected the loading of a model antibiotic, colistin. Weeks-long release of antibiotic at clinically relevant levels was achieved with several formulations. In vitro assays confirmed that the released colistin maintained its antibiotic activity against several bacterial targets. Our results suggest that this method is a valuable tool in the development of novel therapeutic approaches for the treatment of severe complex, infected craniofacial injuries.

Abstract
The present work investigated the osteogenic potential of injectable, dual thermally and chemically gelable composite hydrogels for mesenchymal stem cell (MSC) delivery in vitro and in vivo. Composite hydrogels comprising copolymer macromers of N-isopropylacrylamide were fabricated through the incorporation of gelatin microparticles (GMPs) as enzymatically digestible porogens and sites for cellular attachment. High and low polymer content hydrogels with and without GMP loading were shown to successfully encapsulate viable MSCs and maintain their survival over 28 days in vitro. GMP incorporation was also shown to modulate alkaline phosphatase production, but enhanced hydrogel mineralization along with higher polymer content even in the absence of cells. Moreover, the regenerative capacity of 2 mm thick hydrogels with GMPs only, MSCs only, or GMPs and MSCs was evaluated in vivo in an 8 mm rat critical size cranial defect for 4 and 12 weeks. GMP incorporation led to enhanced bony bridging and mineralization within the defect at each timepoint, and direct bone-implant contact as determined by microcomputed tomography and histological scoring, respectively. Encapsulation of both GMPs and MSCs enabled hydrogel degradation leading to significant tissue infiltration and osteoid formation. The results suggest that these injectable, dual-gelling cell-laden composite hydrogels can facilitate bone ingrowth and integration, warranting further investigation for bone tissue engineering.

Abstract
OBJECTIVE The occurrence of yeast infections in humans has increased, with the species belonging to genus Candida still being the most common cause of infection. Nevertheless, infections caused by less common yeasts have been widely reported in recent years. The main objective of this study was to assess the potential of these less common saprophytic yeasts to invade the host cell, which is essential for causing systemic infections. MATERIAL AND METHODS Various yeast isolates were identified by DNA sequence information of PCR amplified ITS region. The purported saprophytic yeasts were characterized for internalization by mammalian cells in vitro, by staining the F-actin. CONCLUSION The identification of different yeast isolates from various patients revealed that 70% of the isolates belonged to the genus Candida, while remaining 30% of the isolates were yeasts not belonging to genus Candida. These non-Candida clinical isolates, either in yeast or hyphal forms, were efficiently internalized by human epithelial cells. The internalization was marked by a process of actin polymerization surrounding the invading yeast. Such uptake by epithelial cells signifies traversal of cell barrier by yeast cells during infection in vivo.

Abstract
The hepatitis C virus (HCV) epidemic was forecasted through 2030 for 15 countries, and the relative impact of two scenarios was considered: (i) increased treatment efficacy while holding the treated population constant and (ii) increased treatment efficacy and increased annual treated population. Increasing levels of diagnosis and treatment, in combination with improved treatment efficacy, were critical for achieving substantial reductions in disease burden. In most countries, the annual treated population had to increase several fold to achieve the largest reductions in HCV-related morbidity and mortality. This suggests that increased capacity for screening and treatment will be critical in many countries. Birth cohort screening is a helpful tool for maximizing resources. In most of the studied countries, the majority of patients were born between 1945 and 1985.

Abstract
Morbidity and mortality attributable to chronic hepatitis C virus (HCV) infection are increasing in many countries as the infected population ages. Models were developed for 15 countries to quantify and characterize the viremic population, as well as estimate the number of new infections and HCV related deaths from 2013 to 2030. Expert consensus was used to determine current treatment levels and outcomes in each country. In most countries, viremic prevalence has already peaked. In every country studied, prevalence begins to decline before 2030, when current treatment levels were held constant. In contrast, cases of advanced liver disease and liver related deaths will continue to increase through 2030 in most countries. The current treatment paradigm is inadequate if large reductions in HCV related morbidity and mortality are to be achieved.

Abstract
Chronic hepatitis C virus (HCV) infection is a leading cause of liver related morbidity and mortality. In many countries, there is a lack of comprehensive epidemiological data that are crucial in implementing disease control measures as new treatment options become available. Published literature, unpublished data and expert consensus were used to determine key parameters, including prevalence, viremia, genotype and the number of patients diagnosed and treated. In this study of 15 countries, viremic prevalence ranged from 0.13% in the Netherlands to 2.91% in Russia. The largest viremic populations were in India (8 666 000 cases) and Russia (4 162 000 cases). In most countries, males had a higher rate of infections, likely due to higher rates of injection drug use (IDU). Estimates characterizing the infected population are critical to focus screening and treatment efforts as new therapeutic options become available.

Abstract
Hepatocellular carcinoma (HCC) is one of the major causes of morbidity, mortality and healthcare expenditure in patients with chronic liver disease. There are no consensus guidelines on diagnosis and management of HCC in India. The Indian National Association for Study of the Liver (INASL) set up a Task-Force on HCC in 2011, with a mandate to develop consensus guidelines for diagnosis and management of HCC, relevant to disease patterns and clinical practices in India. The Task-Force first identified various contentious issues on various aspects of HCC and these issues were allotted to individual members of the Task-Force who reviewed them in detail. The Task-Force used the Oxford Center for Evidence Based Medicine-Levels of Evidence of 2009 for developing an evidence-based approach. A 2-day round table discussion was held on 9th and 10th February, 2013 at Puri, Odisha, to discuss, debate, and finalize the consensus statements. The members of the Task-Force reviewed and discussed the existing literature at this meeting and formulated the INASL consensus statements for each of the issues. We present here the INASL consensus guidelines (The Puri Recommendations) on prevention, diagnosis and management of HCC in India.

Abstract
BACKGROUND A previous study has shown that shorter bevacizumab infusions (0.5 mg/kg/min) can be safely administered without increasing the risk of infusion-related hypersensitivity reactions (HSRs). However, the risk of proteinuria and hypertension in patients receiving shorter infusions of bevacizumab is undetermined. PATIENTS AND METHODS This was a multicenter, prospective, observational study in patients receiving <10 mg/kg of bevacizumab infused over 0.5 mg/kg/min. Patients were observed until discontinuation of bevacizumab for progression of cancer or toxicity. The incidence of hypertension and proteinuria was compared with a prior cohort of patients who had received standard duration infusions of bevacizumab. RESULTS Sixty-three patients received a total of 392 doses of shorter bevacizumab infusions. Nineteen (30.2%) patients experienced proteinuria while receiving bevacizumab. Out of 19 patients, 13 had grade 1 and 6 had grade 2 proteinuria. None of the patients experienced grade 3 or 4 proteinuria. Hypertension was reported in 32 (50.8%) patients receiving bevacizumab. Twelve (19%) patients developed grade 3 or greater hypertension on bevacizumab. The incidence of proteinuria and hypertension was 38.3% and 56.6%, respectively, in patients (N = 120, 1347 infusions) receiving standard duration infusions of bevacizumab. CONCLUSIONS Shorter bevacizumab infusions (0.5 mg/kg/min) do not increase the risk of proteinuria and hypertension.

Abstract
BACKGROUND AND AIM The role of insulin resistance (IR) and hepatic steatosis in fibrogenesis in chronic hepatitis C infection (CHC) has yielded conflicting data and few studies have been performed in Asian-region populations. We retrospectively investigated the relationship between host metabolic variables, including IR and hepatic steatosis, to hepatic fibrosis in Asian-region CHC genotype 2/3 patients. METHODS A total of 303 treatment-naïve Asian-region patients with CHC genotype 2/3 were enrolled in a multicenter phase 3 study of albinterferon alfa-2b plus ribavirin for 24 weeks. IR was defined as Homeostasis Model for Assessment of IR (HOMA-IR) > 2. Baseline liver biopsy was evaluated by a single expert histopathologist. Post hoc subgroup logistic regression modeling selected for independent variables associated with significant fibrosis (METAVIR stage F2-F4). RESULTS Insulin resistance was available in 263 non-diabetic Asian-region patients (hepatitis C virus-2 [HCV-2] = 171, HCV-3 = 92), and 433 non-Asian region patients (407 "Caucasian"); METAVIR fibrosis prevalence F0-F1 (minimal fibrosis)= 201 (77%) and F2-F4 (significant fibrosis) = 59 (23%), and steatosis prevalence of grade 0 = 169 (65%), grade 1 = 64 (25%), grade 2/3 = 27 (10%). Median HOMA-IR was 1.8 (interquartile range: 1.2-2.7); 100 (38%) patients had HOMA-IR > 2. Factors independently associated with significant fibrosis included HOMA-IR (odds ratio [OR]= 8.42), necro-inflammatory grade (OR = 3.17), age (OR = 1.07) and serum total cholesterol levels (OR = 0.008). This was similar to non-Asian region patients, but steatosis was not associated with significant fibrosis in either cohort. CONCLUSIONS In this subgroup study of Asian-region HCV genotype 2 or 3 patients, insulin resistance, along with age, cholesterol levels and necro-inflammation, but not steatosis may be associated with significant hepatic fibrosis.

Abstract
OBJECTIVES Nonalcoholic fatty liver disease (NAFLD) is commonly associated with type 2 diabetes mellitus (DM) though its prevalence is not well studied. We conducted a prospective study of prevalence and risk factors of NAFLD in patients with type 2 diabetes. RESEARCH DESIGN AND METHODS 204 type 2 DM patients attending an out-patient diabetic clinic underwent abdominal sonography. Ninty of 127 patients with fatty infiltration on ultrasound consented for liver biopsy, clinical and biochemical workup. RESULTS Eighty seven percent had NAFLD on histology with 62.6% steatohepatitis and 37.3% fibrosis. Age, duration of diabetes mellitus, degree of glycemic control, body mass index, waist circumference, family history of diabetes mellitus, did not predict the presence or severity of NAFLD or fibrosis. Serum alanine aminostranferase (ALT) and alkaline phosphatase levels, though within normal limits, were significantly higher in patients with steatohepatitis. Prevalence of NASH increased with increase in the components of the metabolic syndrome. Serum AST/ALT ratio were also significantly higher (p-0.049) in patients with severe fibrosis. All patients with severe fibrosis had metabolic syndrome. CONCLUSIONS Prevalence of NAFLD and NASH in our cohort of type 2 DM patients is high and increases with multiple components of metabolic syndrome. NASH and advanced fibrosis can occur in diabetic patients without any symptoms, signs or routine laboratory test abnormalities.

Abstract
Nevirapine induced hepatotoxicity is known but fatality is rare. We report a case of a young individual who developed nevirapine (NVP) induced fatal hepatitis without apparent risk factors or preceding rash. Exacerbation of underlying silent chronic liver dysfunction possibly contributed to the fatal outcome. This case stresses the need for careful evaluation, regular monitoring and prompt omission of drug on suspicion of hepatotoxicity.

Abstract
Multiple options exist for managing complex abdominal wall defects. These options range from the use of autologous tissue with rearrangement procedures to the use of prosthetic or bioprosthetic materials. All options rely on a thorough understanding of the structural and functional anatomy of the abdominal wall and the relationship of varying anatomical structures to provide the optimal reconstructive procedure. A successful reconstruction is achieved when the structural anatomy is integrated with understanding the dynamic function of the abdominal wall.

Abstract
OBJECTIVE Taxanes are commonly used anticancer agents with a potential of producing an allergic or hypersensitivity reaction (HSR). We performed a randomized study to evaluate the value of a test dose given prior to the full dose of either paclitaxel or docetaxel. RESEARCH DESIGN AND METHODS Patients were randomly assigned to either the administration of the full dose or to the prior administration of a 1 mg intravenous test dose of either paclitaxel or docetaxel. The primary endpoints were severity of the HSR and the cost of drug wastage due to a HSR. RESULTS Two hundred and eighteen patients were randomized from three different treatment sites. The overall incidence of HSR was 6.5% and there was no significant difference in the incidence of HSR in either group. The mean HSR severity grade was 2.8 for patients without a test dose and 2.3 for those receiving a test dose. There was, however, a reduction in the wastage of taxane in the test dose arm. Wastage avoided in the test dose arm was $1573 per patient who had a HSR and $104 per patient treated with a taxane. CONCLUSION Although a test dose may not reduce the severity of a HSR with the administration of a taxane, it does reduce the cost associated with drug wastage.

Abstract
Advances in molecular virology and availability of new antiviral agents have made a positive impact on the treatment of hepatitis B. It is important to know the natural history of hepatitis B virus as high amount of virus may remain in the body for long periods of time without any significant liver disease. Whilst reactivation or mutation of hepatitis B virus and immune clearance may be associated with liver injury leading at times to liver failure. Serological and virological tests are routinely available to systematically evaluate a patient who is detected to have Hepatitis B virus infection. International guidelines have been formulated to suggest appropriate selection of the patient and drug for effective treatment. Therapeutic strategies for total eradication of hepatitis B virus from the liver still remain elusive. However it is now possible to ameliorate liver disease and alter the natural history with effective long-term suppression of the hepatitis B virus. New formulations of existing drugs and newer antiviral agents are constantly being looked into in clinical trials in the pursuit of an ideal therapy.
