RESUMO
Soil carbon (C) loss is the prime sign of land degradation, and C pools have a great impact on soil quality and climate change mitigation. Hence, a field experiment was conducted for three consecutive years to assess the impact of crop intensification and conservation tillage practices on changes in the C pool at different soil depths of marginal land of the Indian Himalayas. The experiment consisted of two intensified cropping systems viz., CS1-Summer maize (Zea mays L.) -rainy season maize-lentil (Lens esculenta L.) and CS2-Summer maize-rainy season maize-mustard (Brassica juncea (L.) Czern) and five tillage practices viz., No-till (NT); NT + live mulch of cowpea (NT + LMC); reduced tillage (RT); RT + LMC and conventional tillage (CT). Results revealed that CS2 produced significantly higher biomass, C retention efficiency (9.85%), and sequestrated greater C (0.42 Mg ha-1 yr-1) in the soil system than CS1. Of the various tillage practices, RT + LMC registered higher biomass and recycled greater biomass and C than those under other tillage practices. However, the highest soil organic carbon (SOC) content (7.03 g kg-1) and pool (9.62 Mg ha-1) in 0-10 cm depth were observed under NT + LMC. The non-labile C pool size under NT in 0-10 cm and 10-20 cm depths was significantly greater than those under CT. The NT + LMC sequestrated significantly higher SOC (0.57 Mg ha-1 yr-1) than other tillage practices. Thus, the study indicated that the adoption of an intensified maize-based system under RT + LMC or NT + LMC would increase SOC storage and C sequestration in marginal lands of the Indian Himalayas.

BACKGROUND: Hepatic expression of microRNA-107 is ubiquitously upregulated in various metabolic diseases. In our previous study, we had demonstrated that fatty acid synthase (FASN) is a target of miR-107. miR-107-FASN interaction, by inducing endoplasmic reticulum (ER) stress, promotes lipid accumulation in hepatocytes. Here, we explore the possible mechanism(s) of the miR-107-FASN-ER stress on hepatic lipid metabolism. METHODS: HepG2 cells were transfected with the scramble or miR-107 and/or its inhibitor. Transcript levels of lipid droplet membrane proteins, apolipoproteins and ß-oxidation genes were quantified by quantitative reverse transcription-PCR. Cells were treated with tunicamycin (Tm, 1 h) and 4-PBA (4-phenyl butyric acid, 8 h) or transfected with hydroxyacyl-CoA dehydrogenase/3-ketoacyl-CoA thiolase/enoyl-CoA hydratase, apha subunit (HADHA) short interfering RNA or its overexpression vector. Mice were injected with the scramble or mmu-miR-107 (2.5 mg kg(-1) body weight) and random glucose levels were measured and oral glucose tolerance test was performed. Serum levels of cholesterol, triglyceride and serum glutamic oxaloacetic transaminase/serum glutamic-pyruvic transaminase (SGOT/SGPT) were evaluated. Hepatic tissues were collected to estimate levels of miR-107 and mitochondrial ß-oxidation genes. Six-micrometer-thick cryosections of hepatic tissues were prepared and stained with Oil Red O for lipid accumulation. RESULTS: miR-107 does not alter the expression of lipid metabolism-related transcription factors, lipid droplet components and apolipiprotein B. miR-107 significantly decreased the levels of the mitochondrial ß-oxidation enzyme, HADHA in HepG2 cells (P<0.01), which was prevented by the miR-107 inhibitor. Similar decrease was observed with Tm (P<0.001), suggesting that HADHA inhibition is promoted by ER stress induction. Interestingly, miR-107-mediated HADHA suppression was rescued by the ER stress inhibitor, 4-PBA (P<0.01). HADHA overexpression rescued miR-107-induced lipid accumulation (P<0.01). miR-107 injection in mice increased random blood glucose levels (P<0.05) and impaired glucose tolerance (P<0.05). Hepatic levels of Hadha were significantly decreased (P<0.001 and P<0.05) accompanied by increased lipid accumulation (P<0.001). CONCLUSIONS: miR-107 promotes hepatic lipid accumulation by suppressing transcript levels of HADHA, induces hyperglycemia and impairs glucose tolerance. We conclude that miR-107 regulation of fatty acid oxidation is an important contributor toward hepatic lipid accumulation.

BACKGROUND: HBA1c is used as an indicator for the long-term control of the glycaemic state and outcome predictors in diabetic patients. Diabetic patients have an increased risk of post-operative complications especially those related to infection. The aim of our study is to ascertain the relationship between HBA1c levels and post-operative recovery within the subspecialty of gynaecological oncology. METHOD: Prospective cohort study during the period 1 August 2012 through 31 August 2014. Preoperative measurement of HBA1c on all gynaecological oncology patients that underwent major surgery. Patient variables collected and analysed were BMI (kg/m(2)), length of stay (LOS in days), cancer stage (stage 1 through stage 4), infective complications, non-infective complications and readmission to hospital. RESULTS: A total of 300 patients were included in our study, 34 of them were known to be diabetic while 266 were presumed to be non-diabetic. Of the presumed non-diabetic cohort, 17.3 % (46/266) had impaired glucose tolerance or diabetes. Mean BMI was significantly increased in the pre-existing diabetic group (32.8 vs. 29.3 kg/m(2), p = 0.016). Infective complications were almost double the rate amongst the known diabetic women than those presumed to be non-diabetic (32.4 vs. 18.0 %, p = 0.048). Rate of re-admission to hospital due to complications was 20.6 % in the diabetic group and 4.1 % within the presumed non-diabetic group (p < 0.001). Infective complications occurred in 16.9 % of women with HBA1c <42 mmol/mol, 22.7 % of those with HBA1c of 42-47 mmol/mol, 43.5 % of patients with HBA1c 48-64 mmol/mol and 37.5 % of patients with HBA1c >64 mmol/mol. Non-infective complications were also more frequent in women with elevated HBA1c (11.1, 22.7, 26.1 and 12.5 % in those women with HBA1c <42, 42-47, 48-64 and >64 mmol/mol, respectively). Re-admission to hospital within 30 days for a complication of surgery occurred in 4.4 % of women with HBA1c <42 mmol/mol, 4.5 % of women with HBA1c measured at 42-47 mmol/mol, 30.8 % of those with HBA1c 48-64 mmol/mol and 25 % of women with HBA1c >64 mmol/mol. CONCLUSION: Preoperative measurement of HBA1c may identify patients (both diabetic and non-diabetic women) at higher risk of postoperative complications and could be used as a trigger for modification of the perioperative management of such patients.

BACKGROUND/AIM: According to recent studies up to 80% of patients would like to receive more information about how cancer treatments can affect their sexual functioning. Moreover, 75 % of them would not feel comfortable being the first to bring up the subject. Our Gynaecological Advice Clinic was established in 2006 at the Christie Hospital and offers support to cancer patients who face sexuality issues. A previous evaluation established that the service sees approximately, 200 patients per year. The aims of this study are to evaluate the service by collecting data relating to levels of attendance, type and amount of clinical activity and to explore further patients' experiences and management. METHODS: This is a retrospective study which was carried out in 2012-2013. Different models are used to evaluate our patients including history taking integrated therapy model, consultations to understand the normal anatomy and physiology with the use of diagrams and photographs, psycho-education and the international classification "Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition" (DSMV). The treatment options advised include medications such as hormone replacement treatment, testosterone, antidepressant, local oestrogen, tibolone, aqueous cream, lubrication to introitus, diprobase, dermal cream and advice for massage to areas of discomfort. Moreover, the use of vaginal dilators, the role of pelvic floor exercises, vulval care and self examination are explained. The team works closely with the psycho-oncology department. The most frequently discussed topics that were covered during the consultation are analysed. RESULTS: 41 outpatient clinics were held between 2012 and 2013. 194 patients attended those clinics during the study period. Single and not group therapy was offered to all the participants. 216 patients were offered appointments while 194 patients actually attended (90%). Patients' age ranged from 24 to 91 years with a mean age of 59 years. 45% had endometrial and 32% cervical cancer, 18% vulval cancer, 4 % ovarian cancer. 74% attended on their own while 18% with their partners and 8% with another family member or friend. 98% of the patients had confidence/trust in the healthcare professional. 95% felt involved with treatment decisions. 82% reported completely understanding information about side-effects. 16% were unaware of who to contact once they had completed treatment. 8% were attending for on-going help with psycho-sexual concerns following completion of treatment. CONCLUSION: The clinic was positively evaluated by patients, they had a high level of trust in the nurses running the service and they found it beneficial. Consultations were generally lasting 20-30 min and most patients reported this was an appropriate length. It once again highlights that although the service was set-up to address psycho-sexual concerns, in reality it dealt with a variety of other patient concerns. Due to the success of the clinic, the service has expanded and we are now supporting patients from other tumour groups such as colorectal, urology and plastic surgery.

RESUMO
Data on age and body weight at breeding, parity, previous litter size, days open and some descriptive body linear traits from 389 meat-type, prolific Black Bengal goats in Tripura State of India, were collected for 3 and 1/2 years (2007 to 2010) and analyzed using logistic regression model. The objectives of the study were i) to evaluate the effect of age and body weight at breeding, parity, previous litter size and days open on litter size of does; and ii) to investigate if body linear type traits influenced litter size in meat-type, prolific goats. The incidence of 68.39% multiple births with a prolificacy rate of 175.07% was recorded. Higher age (>2.69 year), higher parity order (>2.31), more body weight at breeding (>20.5 kg) and larger previous litter size (>1.65) showed an increase likelihood of multiple litter size when compared to single litter size. There was a strong, positive relationship between litter size and various body linear type traits like neck length (>22.78 cm), body length (>54.86 cm), withers height (>48.85 cm), croup height (>50.67 cm), distance between tuber coxae bones (>11.38 cm) and distance between tuber ischii bones (>4.56 cm) for discriminating the goats bearing multiple fetuses from those bearing a single fetus.
RESUMO
SUMMARY: The Women's Health Initiative (WHI) double-blind, placebo-controlled clinical trial randomly assigned 36,282 postmenopausal women in the U.S. to 1,000 mg elemental calcium carbonate plus 400 IU of vitamin D(3) daily or placebo, with average intervention period of 7.0 years. The trial was designed to test whether calcium plus vitamin D supplementation in a population in which the use of these supplements was widespread would reduce hip fracture, and secondarily, total fracture and colorectal cancer. INTRODUCTION: This study further examines the health benefits and risks of calcium and vitamin D supplementation using WHI data, with emphasis on fractures, cardiovascular disease, cancer, and total mortality. METHODS: WHI calcium and vitamin D randomized clinical trial (CT) data through the end of the intervention period were further analyzed with emphasis on treatment effects in relation to duration of supplementation, and these data were contrasted and combined with corresponding data from the WHI prospective observational study (OS). RESULTS: Among women not taking personal calcium or vitamin D supplements at baseline, the hazard ratio [HR] for hip fracture occurrence in the CT following 5 or more years of calcium and vitamin D supplementation versus placebo was 0.62 (95 % confidence interval (CI), 0.38-1.00). In combined analyses of CT and OS data, the corresponding HR was 0.65 (95 % CI, 0.44-0.98). Supplementation effects were not apparent on the risks of myocardial infarction, coronary heart disease, total heart disease, stroke, overall cardiovascular disease, colorectal cancer, or total mortality, while evidence for a reduction in breast cancer risk and total invasive cancer risk among calcium plus vitamin D users was only suggestive. CONCLUSION: Though based primarily on a subset analysis, long-term use of calcium and vitamin D appears to confer a reduction that may be substantial in the risk of hip fracture among postmenopausal women. Other health benefits and risks of supplementation at doses considered, including an elevation in urinary tract stone formation, appear to be modest and approximately balanced.

We have isolated ν(µ) charged-current quasielastic (QE) interactions occurring in the segmented scintillator tracking region of the MINERvA detector running in the NuMI neutrino beam at Fermilab. We measure the flux-averaged differential cross section, dσ/dQ², and compare to several theoretical models of QE scattering. Good agreement is obtained with a model where the nucleon axial mass, M(A), is set to 0.99 GeV/c² but the nucleon vector form factors are modified to account for the observed enhancement, relative to the free nucleon case, of the cross section for the exchange of transversely polarized photons in electron-nucleus scattering. Our data at higher Q² favor this interpretation over an alternative in which the axial mass is increased.
RESUMO
We report a study of ν(µ) charged-current quasielastic events in the segmented scintillator inner tracker of the MINERvA experiment running in the NuMI neutrino beam at Fermilab. The events were selected by requiring a µ- and low calorimetric recoil energy separated from the interaction vertex. We measure the flux-averaged differential cross section, dσ/dQ², and study the low energy particle content of the final state. Deviations are found between the measured dσ/dQ² and the expectations of a model of independent nucleons in a relativistic Fermi gas. We also observe an excess of energy near the vertex consistent with multiple protons in the final state.
RESUMO
Brachial plexus injury is not uncommon in our country like Bangladesh and it causes functional damage and physical disability of the upper limbs. Most of the cases were caused by motor vehicle accident. We have conducted a prospective study for the operative treatment of 105 adult traumatic brachial plexus injury cases in Hand unit in the department of Orthopaedics, Bangabandhu Sheikh Mujib Medial University (BSMMU) during January 2012 to July 2019. The main surgical options for brachial plexus injury include primary reconstructive surgery such as neurolysis, direct repair, nerve graft, nerve transfer (neurotization) and possibly free functioning (gracilis) muscle transfer and secondary reconstructive procedure such as tendon transfer, arthrodesis, FFMT and bony procedure. Each of these procedures is used either alone or in combination for particular clinical scenarios. Aims and objectives of this study was to restoration of shoulder abduction and external rotation, elbow flexion and hand function are goal of treatment of adult traumatic brachial plexus injury. Age range was from 14 years to 55 years (mean age 26 years). Male were 95 and female were 10 cases. Time from trauma to surgery was valid 3 months to 9 months. Motor cycle accident was most common mechanism of injury. Upper plexus (C5, C6) injury was 52 cases, extended upper plexus (C5, C6 & C7) injury was 19 cases and global brachial plexus injury was 34 cases. When there is high suspicion of root avulsions, early exploration and reconstruction is indicated. Operate these patients 2-3 months after their injury. In other patients without high suspicion of root avulsion, we routinely perform exploration between 3 to 6 months after injury when no adequate sign of recovery are present. Common reconstructive options are any injury with neuroma in continuity with conductive nerve action potential (NAP): only neurolysis or any injury with nerve rupture or postganglionic neuroma not conducting nerve Action potential (NAP) and good proximal nerve: Direct repair or repair with nerve graft or nerve transfer if possible. Follow up period from 6 months to 6 years. The best results were obtained in C5, C6 and C5, C6 & C7 brachial plexus injury cases. SAN to SSN, Oberlin II and long head triceps motor branch to anterior division of axillary nerve transfer for C5 & C6 injury or upper plexus injury and in addition intercostals nerve to anterior division of axillary nerve and AIN branch of median nerve to ECRB for C5, C6 & C7 (extended upper plexus injury). Extra-plexus and intra-plexus neurotization was done in global brachial plexus injury cases and 5 cases by contra-lateral C7 to median nerve by vascularised ulnar nerve graft and only 2 cases contra-lateral C7 to lower trunk through pre spinal or pre tracheal route were done and only one case by FFMT. Few cases gain shoulder abduction and elbow flexion but no improvement of hand function and most cases even by FFMT still in follow up. Results of surgical treatment of upper and extended upper brachial plexus injury cases were satisfactory on the other hand recovery of shoulder abduction and elbow flexion was acceptable and comparable to other study in global brachial plexus injury and recovery of hand function were poor.

Tumors in the hand are relatively uncommon but 95% are benign. Tumors occurring in the hand, forearm and arm often have unique growth patterns and potential for metastasis that may be different from those seen elsewhere in the body. Secondary metastatic tumors in the hand are very rare (0.1%). Diagnosis is mainly clinical, but X-ray, USG and MRI help as a diagnostic aid. The aim of the study was to early diagnosis, see the pattern and proper management of the hand tumor and ensure good hand function. This prospective study was done from January 2004 to July 2019. We found 220 hand tumors in the hand unit, Department of Orthopaedic Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka Bangladesh. Among 220 patients, male were 114(51.81%) and female were 106 (48.19%). Out of 220 patients we found 190(86.36%) benign tumor and tumor like lesions and 30(13.64%) was malignant hand tumors. Out of 190 benign lesions, benign tumor was 158(83.15%) and 32(16.85%) was tumor like lesions. Among 158 benign tumor, bone tumors were 40(25.31%) and soft tissue tumours were 138(74.69%). Out of soft tissue tumor, peripheral nerve tumor was 20(12.66%). Enchondroma and Giant cell tumors are the most common among the benign bone tumors, on the other hand giant cell tumors of tendon sheath, Glomus tumor, haemangioma, neurofibroma, schwanoma are the common soft tissue tumors. Compound palmar ganglion, fibromatosis and tuberculosis of phalanx are the most common tumor like lesions. Synovial sarcoma 10(33.33%), osteosarcoma 03(10%), chondrosarcoma 03(10%), ewings sarcoma 02(6.66%), fibrosarcoma 04 (13.33%), Malignant fibrous histocytoma 01(3.33%), soft tissue sarcoma 01(3.33%), Merkel cell tumor 01(3.33%), pleomorphic Rabdomyosarcoma 01(3.33%), malignant melanoma 01(3.33%), clear cell sarcoma of tendon and aponeurosis 01(3.33%), undifferentiated carcinoma 01(3.33%) and extra skeletal chondro sarcoma 01(3.33%) were the malignant tumors. Most of the benign lesions recovered fully after excision except neurofibroma and malignant tumors were treated with excision (including amputation) and chemo-radiotherapy successfully, but 4 patients were refereed to higher center due to recurrence and deteriation of hand function and one patient died due to metastasis. Malignant hand tumor management is very difficult even after amputation with multidisciplinary approach. Hand tumor is uncommon and malignant tumors are rare but any abnormal lump or bump in the hand or wrist is considered as tumor. Early detection and intervention are essential for better prognosis and survival for malignant tumors of hands and upper limbs.

BACKGROUND: The replacement of traditional oils with a camphor and menthol-based eutectic mixture is done to prepare oil-less emulsion-like dispersions for co-delivery of cinnarizine (CNZ) and morin hydrate (MH) for managing Meniére's disease (MD). Since two drugs are loaded into the dispersions, the development of a suitable reverse phase-high performance liquid chromatography (RP-HPLC) method for their simultaneous analysis becomes inevitable. OBJECTIVE: By applying the analytical quality by design (AQbD) approach, the RP-HPLC method conditions were optimized for the concomitant determination of two drugs. METHODS: The systematic AQbD started with identifying critical method attributes (CMA) through an Ishikawa fishbone diagram, risk estimation matrix, and risk priority number-based failure mode effect analysis followed by screening using fractional factorial design and optimization by face-centered central composite design. The concomitant determination of two drugs by the optimized RP-HPLC method condition was substantiated via specificity checking using combined drug solution, drug entrapment efficiency, and in vitro release of the two drugs from emulsion-like dispersions. RESULTS: The AQbD optimized RP-HPLC method conditions revealed the retention time for CNZ and MH at 5.017 and 5.323, respectively. The studied validation parameters were found within the ICH-prescribed limits. Exposing the individual drug solutions to acidic and basic hydrolytic conditions yielded extra chromatographic peaks for MH, probably due to the degradation of MH. The DEE % values of 87.40 ± 4.70 and 74.79 ± 2.94, respectively, were noticed for CNZ and MH in emulsion-like dispersions. More than 98% CNZ and MH release was occurred from emulsion-like dispersions within 30 min post-dissolution in artificial perilymph. CONCLUSIONS: Overall, the AQbD approach could be helpful for systematic optimization of RP-HPLC method conditions to estimate concomitantly other therapeutic moieties. HIGHLIGHTS: The proposed article shows the successful application of AQbD for the optimization of RP-HPLC method conditions to concomitantly estimate CNZ and MH in combined drug solution and dual-drug-loaded emulsion-like dispersions.

Earlier we have shown that exogenous expression of HIPPI, a molecular partner of Huntingtin interacting protein HIP-1, induces apoptosis and increases expression of caspases-1, -8 and -10 in HeLa and Neuro2A cells. The C-terminal pseudo death effector domain of HIPPI (pDED-HIPPI) specifically interacts with the putative promoter sequences of these genes. In the present manuscript, we predict from structural modeling of pDED-HIPPI that R393 of HIPPI is important for such interaction. R393E mutation in pDED-HIPPI decreases the interaction with the putative promoter of caspase-1 in cells. Expression of caspase-1 is decreased in cells expressing mutant pDED-HIPPI in comparison to that observed in cells expressing wild type pDED-HIPPI. Using HIP-1 knocked down cells as well as over expressing HIP-1 with mutation at its nuclear localization signal and other deletion mutations, we demonstrate that translocation of HIPPI to the nucleus is mediated by HIP-1 for the increased expression of caspase-1. HIPPI-HIP-1 heterodimer is detected in cytoplasm as well as in the nucleus and is associated with transcription complex in cells. Taking together, we are able to show the importance of R393 of HIPPI and the role of HIPPI-HIP-1 heterodimer in the transcription regulation of caspase-1.

In 14 patients underwent open adrenalectomy with high-frequency electric welding application (I group), in 8 - open adrenalectomy (II group). The two groups were compared: duration of surgery, blood loss, postoperative pain intensity, duration of postoperative hospitalization, the frequency of intra-and postoperative complications, histological changes in tissues. The advantages of open adrenalectomy with high-frequency electric welding application feel less duration of surgery and estimated blood loss, lack of necrosis in the surrounding tissues and foreign bodies in the wound, reducing the trauma of surgery, improving rehabilitation.

Avascular necrosis (AVN) of femoral head is an increasingly common cause of musculoskeletal disability. Most of the cases caused by steroid induced and traumatic but idiopathic cause are not also uncommon. Almost all the patients presented with pain at the hip, limping gait, restricted movement and difficulty in waking and squatting and becomes disabled. Core decompression and muscle pedicle bone graft at stage IIA, IIB and III provides painless and mobile life. Core decompression supplemented with bone graft to enhance mechanical support and augment healing. We have started a prospective study for the treatment of AVN of Femoral head at stage IIA, IIB and III by core decompression and Tensor fascia lata muscle pedicle bone graft in the department of Orthopaedic surgery Bangabandhu Seikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2009 to December 2019. Aim of the study was to assess the effectiveness of core decompression and tensor fascia lata muscle pedicle bone graft in the treatment of AVN of femoral head at stage IIA, IIB and III. A total 48 patients and 65 hips were operated. Out of 48 patients, male was 30(62.50%) and female was 18(37.5%). Male-Female ratio was 1.66:1. Age of the patients ranging from 20 years to 50 years, mean age 36±4.65 years. According to aetiology corticosteroid induced was 47/65 (72.31%), idiopathic was 8(12.31%), post traumatic was 4(6.15%), ITP was 2(3.08%), ALL was 2(3.08%), and alcohol induced was 2(3.08%) of femoral head involvement. According to Ficat and Arlet's staging, stage IIA hip involvement was 28/65(43.08%), stage IIB was 32(49.23%) and stage III was 5(07.69%). All patients were treated with core decompression along with tensor fascia lata (TFL) muscle pedicle bone graft. All patients were followed clinically and radiologically at regular interval. Follow up period was 6 months to 10 years. Harris hip score (HHS) was used for evaluation of clinical outcome. Among the 65 hips, 24(36.92%) was excellent outcome (HHS >90), 30(46.15%) was good outcome (HHS: 80-90), 7(10.78%) was fair outcome (HHS: 70-79) and 4(6.15%) was poor outcome. For valid statistical analysis excellent and good results were grouped as satisfactory that was 54(83.07%) and fair and poor results were grouped as unsatisfactory that was11(16.93%), p value is <0.001 that is significant.

AIMS/HYPOTHESIS: This study reports the results of the first phase of a national study to determine the prevalence of diabetes and prediabetes (impaired fasting glucose and/or impaired glucose tolerance) in India. METHODS: A total of 363 primary sampling units (188 urban, 175 rural), in three states (Tamilnadu, Maharashtra and Jharkhand) and one union territory (Chandigarh) of India were sampled using a stratified multistage sampling design to survey individuals aged ≥ 20 years. The prevalence rates of diabetes and prediabetes were assessed by measurement of fasting and 2 h post glucose load capillary blood glucose. RESULTS: Of the 16,607 individuals selected for the study, 14,277 (86%) participated, of whom 13,055 gave blood samples. The weighted prevalence of diabetes (both known and newly diagnosed) was 10.4% in Tamilnadu, 8.4% in Maharashtra, 5.3% in Jharkhand, and 13.6% in Chandigarh. The prevalences of prediabetes (impaired fasting glucose and/or impaired glucose tolerance) were 8.3%, 12.8%, 8.1% and 14.6% respectively. Multiple logistic regression analysis showed that age, male sex, family history of diabetes, urban residence, abdominal obesity, generalised obesity, hypertension and income status were significantly associated with diabetes. Significant risk factors for prediabetes were age, family history of diabetes, abdominal obesity, hypertension and income status. CONCLUSIONS/INTERPRETATIONS: We estimate that, in 2011, Maharashtra will have 6 million individuals with diabetes and 9.2 million with prediabetes, Tamilnadu will have 4.8 million with diabetes and 3.9 million with prediabetes, Jharkhand will have 0.96 million with diabetes and 1.5 million with prediabetes, and Chandigarh will have 0.12 million with diabetes and 0.13 million with prediabetes. Projections for the whole of India would be 62.4 million people with diabetes and 77.2 million people with prediabetes.

According to the World Diabetes Atlas, India is projected to have around 51 million people with diabetes. However, these data are based on small sporadic studies done in some parts of the country. Even a few multi-centre studies that have been done, have several limitations. Also, marked heterogeneity between States limits the generalizability of results. Other studies done at various time periods also lack uniform methodology, do not take into consideration ethnic differences and have inadequate coverage. Thus, till date there has been no national study on the prevalence of diabetes which are truly representative of India as a whole. Moreover, the data on diabetes complications is even more scarce. Therefore, there is an urgent need for a large well-planned national study, which could provide reliable nationwide data, not only on prevalence of diabetes, but also on pre-diabetes, and the complications of diabetes in India. A study of this nature will have enormous public health impact and help policy makers to take action against diabetes in India.

Interleukin-2 (IL-2)-deficient (IL-2-/-) mice develop anemia and colonic inflammatory bowel disease. To elucidate the mechanism of this disease, we have bred IL-2-/- mice to two strains of immunodeficient mice, RAG-2-deficient (RAG-2-/-, lacking B and T cells) and JH-deficient mice (JH-/-, lacking B cells). IL-2-/-, RAG-2-/- double-mutant mice are disease free, while IL-2-/-, JH-/- double-mutant mice succumb to bowel disease at the same rate as IL-2-/- littermates. IL-2-/-, JH-/- mice do not, however, succumb to anemia. Thus, spontaneous intestinal inflammation in IL-2-/- mice requires mature T cells, not B cells, while anemia is dependent on B cells.

Cytokines stimulate granulopoiesis through signaling via receptors whose expression is controlled by lineage-specific transcription factors. Previously, we demonstrated that granulocyte colony-stimulating factor (G-CSF) receptor mRNA was undetectable and granulocyte maturation blocked in CCAAT enhancer binding protein alpha (C/EBPalpha)-deficient mice. This phenotype is distinct from that of G-CSF receptor-/- mice, suggesting that other genes are likely to be adversely affected by loss of C/EBPalpha. Here we demonstrate loss of interleukin 6 (IL-6) receptor and IL-6-responsive colony-forming units (CFU-IL6) in C/EBPalpha-/- mice. The observed failure of granulopoiesis could be rescued by the addition of soluble IL-6 receptor and IL-6 or by retroviral transduction of G-CSF receptors, demonstrating that loss of both of these receptors contributes to the absolute block in granulocyte maturation observed in C/EBPalpha-deficient hematopoietic cells. The results of these and other studies suggest that additional C/EBPalpha target genes, possibly other cytokine receptors, are also important for the block in granulocyte differentiation observed in vivo in C/EBPalpha-deficient mice.

BACKGROUND AND OBJECTIVES: Natural orifice transluminal endoscopic surgery involves the introduction of instruments through a natural orifice into the peritoneal cavity to perform diagnostic and therapeutic surgical interventions. We report the utilization of the vaginal opening at the time of laparoscopic-assisted vaginal hysterectomy or total laparoscopic hysterectomy as a natural orifice for appendectomy. METHODS: We reviewed cases of 42 patients who underwent total laparoscopic hysterectomy or laparoscopic-assisted vaginal hysterectomy followed by appendectomy, performed by applying a stapler and removing the appendix transvaginally. By using a small-diameter laparoscope, the appendix was mobilized, especially in patients with adhesions, endometriosis, or retrocecal appendix, to facilitate transvaginal access with the stapler. RESULTS: All procedures were performed successfully without intraoperative or major postoperative complications. The appendectomy portion of the procedure took approximately 5 minutes to 10 minutes. Appendiceal pathology included serosal adhesions (14), fibrous obliteration of the lumen (12), endometriosis (4), serositis (2), and carcinoid tumor (1), among others. CONCLUSIONS: Appendectomy performed with an endoscopic stapler introduced transvaginally for amputation and retrieval following total laparoscopic hysterectomy or laparoscopically assisted vaginal hysterectomy appears to be a safe and effective modification of established techniques with acceptable outcomes.
