Abstract
OBJECTIVES World Health Organization (WHO) guidelines for health programmes and healthcare delivery are the foundation of its technical leadership in public health and essential to decision-making globally. A key function of guideline development is to identify areas in which further evidence is needed because filling these gaps will lead to future improvements in population health. The objective of this study was to examine the knowledge gaps and research questions for addressing those gaps generated through the WHO guideline development process, with the goal of informing future strategies for improving and strengthening the guideline development process. STUDY DESIGN We did a systematic, retrospective analysis of research questions identified in the published guidelines. METHODS We analyzed guidelines published between January 1, 2008, and December 31, 2018, by the Communicable Diseases Cluster in five disease areas: tuberculosis (TB), HIV, malaria, TB-HIV, and neglected tropical diseases (NTDs). Research questions were extracted independently by two researchers. We analyzed the distribution of research questions by disease and by topic category and did a qualitative assessment of optimum practice for research question generation during the guideline development process. RESULTS A total of 48 guidelines were included: 26 on HIV, 1 on malaria, 11 on TB, 5 on TB/HIV, and 5 on NTDs. Overall, 36 (75%) guidelines encompassed a total of 360 explicit research questions; the remainder did not contain specific research questions. The number of research questions that focused on TB was 49, TB/HIV was 38, HIV was 250, and NTDs was 23. The number of research questions that focused on diagnosis was 43 (11.9%) of 360, prevention was 62 (17.2%), treatment was 103 (28.6%), good practice was 12 (3.3%), service delivery was 86 (23.8%), and other areas was 54 (15%). Research questions were often not formulated in a specific or actionable way and were hard to identify in the guideline. Examples of good practice identified by the review team involved the generation of specific and narrowly defined research questions, with accompanying recommendations for appropriate study design. CONCLUSIONS The WHO must strengthen its approach to identifying and presenting research questions during the guideline development process. Ensuring access to research questions is a key next step in adding value to the guideline development process.

Abstract
Nonosseous or soft tissue Ewing's sarcoma is a rare form of Ewing's sarcoma/primitive neuroectodermal tumour that seldom affects the head and neck region. Involvement of the nose and paranasal sinuses is extremely uncommon, with only eight of such patients being reported to date, mostly affecting adolescents and young adults. To our knowledge, this study is the first comprehensive report of primary soft tissue Ewing's sarcoma involving the paranasal sinuses in an elderly patient who successfully completed treatment. We herein discuss the pathogenesis, management and factors affecting the prognosis of this rare group of tumours involving the nose and paranasal sinuses, in relation to the available literature.

Abstract
Fifty-one lactic acid bacteria (LAB) strains were isolated and identified based on 16S ribosomal DNA sequence from the intestinal tracts of 142 kuruma shrimps (Marsupenaeus japonicus) collected from Kanmon Strait, Fukuoka and Tachibana Bay, Nagasaki, Japan. Cellular immunomodulatory function of 51 isolated LAB strains was assessed by measuring the level of interferon (IFN)-γ induction in mouse spleen cell culture. The strain Lactococcus lactis D1813 exhibited the highest amount of IFN-γ production and also bactericidal activity and was selected for testing its immunomodulatory role as a probiotic in kuruma shrimp. We also assessed the effect of dietary incorporation of this probiotic on resistance to Vibrio penaeicida infection in the kuruma shrimp. Our results demonstrate that probiotic L. lactis D1813-containing diet-fed (10⁵ cfu g⁻¹) shrimps displayed a significant up-regulation of lysozyme gene expressions in the intestine and hepatopancreas. However, insignificantly higher expression of anti-lipopolysaccharide factor, super oxide dismutase, prophenoloxidase, and toll-like receptor 1 was recorded in the intestine of shrimps fed the probiotic diet. Moreover, significantly increased (P < 0.01) resistance to the bacterial pathogen in term of better post-infection survival (61.7 %) was observed in the shrimps fed with the probiotic-incorporated diet compared with the control diet-fed group (28.3 %). The present study indicates the immunomodulatory role of the LAB L. lactis D1813 on the kuruma shrimp immune system and supports its potential use as an effective probiotic in shrimp aquaculture.

Abstract
Background: The overexpression of oestrogen-related receptor-β (ERRβ) in breast cancer patients is correlated with improved prognosis and longer relapse-free survival, and the level of ERRβ mRNA is inversely correlated with the S-phase fraction of cells from breast cancer patients. Methods: Chromatin immunoprecipitation (ChIP) cloning of ERRβ transcriptional targets and gel supershift assays identified breast cancer amplified sequence 2 (BCAS2) and Follistatin (FST) as two important downstream genes that help to regulate tumourigenesis. Confocal microscopy, co-immunoprecipitation (CoIP), western blotting and quantitative real-time PCR confirmed the involvement of ERRβ in oestrogen signalling. Results: Overexpressed ERRβ induced FST-mediated apoptosis in breast cancer cells, and E-cadherin expression was also enhanced through upregulation of FST. However, this anti-proliferative signalling function was challenged by ERRβ-mediated BCAS2 upregulation, which inhibited FST transcription through the downregulation of β-catenin/TCF4 recruitment to the FST promoter. Interestingly, ERRβ-mediated upregulation of BCAS2 downregulated the major G1-S transition marker cyclin D1, despite the predictable oncogenic properties of BCAS2. Interpretation: Our study provides the first evidence that ERRβ, which is a coregulator of ERα also acts as a potential tumour-suppressor molecule in breast cancer. Our current report also provides novel insights into the entire cascade of ERRβ signalling events, which may lead to BCAS2-mediated blockage of the G1/S transition and inhibition of the epithelial to mesenchymal transition through FST-mediated regulation of E-cadherin. Importantly, matrix metalloprotease 7, which is a classical mediator of metastasis and E-cadherin cleavage, was also restricted as a result of ERRβ-mediated FST overexpression.

Abstract
With the aim of evaluating the effect of a Mongolian dairy product derived Lactobacillus paracasei spp. paracasei (strain 06TCa22) (Lpp) on the cytokine-mediated immune responses to Vibrio harveyi infection, we examined 16 cytokine expressions in the Japanese pufferfish, Takifugu rubripes. Fish were orally treated with the heat-killed Lpp at 1 mg g(-1) body weight d(-1) for 3 days. At 24 h posttreatment, fish were infected by an intramuscular injection of 0.1 mL V. harveyi bacterial suspension (10(8) cfu mL(-1)). Additionally, superoxide anion production (SAP) and phagocytic activity (PA) of head kidney cells were assessed during 120 h postinfection period. Significant up-regulation of pro-inflammatory (IL-1β, IL-6, IL-17A/F-3, TNF-α and TNF-N), cell-mediated immune inducing (IL-12p35, IL-12p40 and IL-18), antiviral/intra-cellular pathogen killing (I-IFN-1 and IFN-γ), anti-inflammatory (IL-10) and lymphocyte agonistic (IL-2, IL-7, IL-15, IL-21 and TGF-β1) cytokines was observed in the treated fish compared to control ones during the pathogen infection. Furthermore, significantly increased SAP and PA (P < 0.01; 0.05) were recorded in the treated fish compared to untreated fish. These results suggest the beneficial role of Lpp in enhancement of cytokine-mediated immunity in the Japanese pufferfish against V. harveyi infection and application of this product as a potential fish immunostimulant.

Abstract
INTRODUCTION The choice of analgesia during prostate biopsy remains controversial. The pain has dual origin: from the insertion of the probe as well as the biopsy itself. Periprostatic nerve block (PPNB) is currently the gold standard modality for decreasing pain of prostate biopsy but it does not alleviate the pain of probe insertion. A randomised controlled trial was performed to test the efficacy and safety of the combination of topical application of diltiazem gel and PPNB for pain control during transrectal ultrasonography guided prostate biopsy. METHODS A total of 73 patients who were to undergo their first prostate biopsy were randomised to receive either 2ml of 2% topical diltiazem gel or a placebo 15 minutes before the biopsy. All the patients then had a PPNB using 1% lignocaine. A ten- point visual analogue scale was used to record the pain immediately after the insertion of the probe and during the biopsy. Any adverse effects were also recorded. RESULTS There was no significant difference in the mean age and prostate volumes between the groups. There was a significantly lower mean pain score due to probe insertion in those patients who received topical diltiazem than in the placebo group (p<0.0001). There was no significant difference between the pain scores during the biopsy itself between the two groups. CONCLUSIONS Topical diltiazem significantly reduces the pain of probe insertion during prostate biopsy and can be used effectively as an adjuvant to PPNB.

Abstract
Cytokine responses in the Japanese pufferfish (Takifugu rubripes) head kidney (HK) cells to heat-killed lactic acid bacteria probiotics isolated from the Mongolian dairy products were investigated by transcriptomic examination. The HK cells were incubated with two heat-killed bacteria, namely Lactobacillus paracasei spp. paracasei (strain 06TCa22) and L. plantarum (strain 06CC2) and the responses of 16 cytokine genes at 0 (control), 1, 4, 8, 12, 24 and 48 h post-stimulation were assayed by multiplex RT-PCR analysis (GenomeLab Genetic Analysis System, GeXPS; Beckman Coulter, Inc.). The 16 genes included in the assay were pro-inflammatory cytokines (IL-1β, IL-6, IL-17A/F-3, TNF-α and TNF-N), cell-mediated immune regulators (IL-12p35, IL-12p40 and IL-18), antiviral (I-IFN-1 and IFN-γ) and other regulatory (IL-2, IL-7, IL-15, IL-21, IL-10 and TGF-β1) cytokines. Despite the differences in the transcriptional profiles, expression of all the cytokines tested here was significantly elevated by both the probiotic bacterial stimulants compared with the unstimulated control. Therefore, this in vitro study has demonstrated the modulation of cytokine defense mechanisms in the HK cells by the two heat-killed probiotics indicating their potentiality as novel immunostimulants to fish. However, strain-dependent varied expression of important cytokines (cell-mediated immune regulators, antiviral and anti-inflammatory cytokines) suggests better efficacy of L. paracasei spp. paracasei strain as fish immunostimulant. Further in vivo studies to elucidate the cytokine regulation networks will validate our present observations. A careful evaluation of ant-inflammatory properties may be undertaken using single strain to affirm the immunostimulatory capability. Moreover, application timings and frequency to assess the longevity of immunostimulant effects and to make the application cost-effective need to be evaluated before any practical use in aquaculture.

Abstract
This cross-sectional study was done to see the association of post thyroidectomy parathyroid failure with thyroid disease and type of surgery. It was carried out in the Department of Otolaryngology-Head and Neck Surgery, Bangabandhu Sheikh Mujib Medical University, Dhaka during the period of July 2008 to June 2010. Total 50 cases of thyroid malignancy and multinodular goiter who had undergone total or near total thyroidectomy with or without neck dissection were studied. In this study highest number of cases were found in 3rd decade of age (28%) and there was female predominance (M:F=1:3.54). Overall frequency of post operative hypocalcaemia was 30% (26% was temporary hypocalcaemia and 4% was permanent). Hypocalcaemia revealed clinically in 20% cases and remained subclinical in 10% cases. Hypocalcaemia developed in 42.30% cases of malignant thyroid disease and 16.66% cases of benign thyroid disease (p<0.05). It was found in 54.54% cases with neck dissection and 23.07% cases without neck dissection (p<0.05). Hypocalcaemia developed in 62.5% cases where parathyroid gland were not identified and 23.8% cases where parathyroid gland was identified. Hypocalcaemia developed most commonly on the 2nd post operative day (73.33%). There is a significance difference with development of parathyroid failure after thyroid surgery between benign and malignant thyroid disease and also between thyroid surgery with or without neck dissection.

Abstract
Cytomegalovirus (CMV) infection is frequent in immunocompromised patients, especially in AIDS, organ transplantation and rarely in Hodgkin's disease and Non-Hodgkin's lymphoma (NHL). We present a case of NHL with CMV oesophagitis, which has rarely been documented in literature. Apart from fungal and herpes simplex infections, as the common differential diagnosis for oesophagitis in patients of lymphoma, CMV should be considered an important etiologic agent. Early diagnosis and prompt treatment of CMV oesophagitis with gancyclovir can avert significant morbidity and avoid unacceptable treatment delays.

Abstract
Advances in cancer management have resulted in a significant increase in median survival of number of diseases. Consequently we are seeing more patients living long enough to develop symptomatic brain metastases. The management of such patients will be discussed here. The most important definitive investigation is contrast enhanced MRI scan of brain. Management consists of supportive care and disease directed treatment. Surgical resection remains the gold standard for the treatment of solitary brain metastases. Whole brain radiotherapy is considered standard treatment for all patients with brain metastases. The role of chemotherapy was limited in the past. Recently several new agents have been identified as potentially useful. Preliminary results indicate that drugs like temozolomide and topotecan have antitumor activity against the brain metastases as well as the primary systemic malignancies. The goal of multimodality treatment for brain metastases is to palliate local symptoms and prevent consequences of neurological involvement.

Abstract
17531 Background: Imatinib is a very active agent in advanced phase CML. The present study assesses the impact of Imatinib therapy on the outcome of Indian patients with CML in Accelerated Phase (AP) and Blast Crisis (BC). Methods: Patients of CML in AP or BC who were treated with Imatinib based therapy between 2001 and 2006 were analyzed retrospectively. Results: A total of 65 patients who received Imatinib based treatment for CML in AP or BC were analyzed. Thirty eight (58.46 %) patients diagnosed in chronic phase (CP) were initiated on Imatinib based treatment at time of progression to AP or BC. The remaining 27 (41.53 %) patients had AP or BC of CML at initial diagnosis. At the time of start of Imatinib treatment 36 (55.38 %) patients had AP and 29 (44.61 %) were in BC. Imatinib as a single agent was used in 41 (63.07 %) patients (27 in AP and 14 in BC) and in combination with oral 6-MP and Etoposide was used in 24 (36.92 %) patients (14 in AP and 10 in BC). Hematological response (HR) was seen in 64.61% (42 out of 65) patients, complete HR in 32 (49.23 %) and partial HR in 10 (15.38 %). Cytogenetic response (CR) was noted in 21 (32.31%) patients (Complete -10, Partial -9, and Minor - 2). Twenty eight (43.07%) patients remained progression free (HR+CR in 16 and only HR in 12 patients) till the last date of follow up (median duration of follow-up was 17 months).For the whole group (n=65) the overall survival from the diagnosis of AP or BC after commencing Imatinib treatment was 65.3%, 51.6% and 34.4% at 1, 2 and 3 years respectively. The median survival was 25 months. The median survival and OS at 1 year, as expected, was significantly better for patients in AP (36 months, 77.4 %) as compared to those in BC (11 months, 48.2%)(p=0.004) and both were much longer than previously reported with non-Imatinib therapy. Outcome in patients with AP or BC was not significantly improved by addition of 6-MP and Etoposide. Temporary discontinuation of Imatinb for grade III/IV toxicity was done in 27 (41.53 %) patients for a median duration of 28 days. Conclusions: Imatinib has improved the outcome of patients with advanced phase CML. Our data also documents this in patients from India. However, Imatinib needs to be studied with newer combinations to achieve long term disease control in patients with CML, particularly those in BC. No significant financial relationships to disclose.

Abstract
The development of gastric carcinoma in a patient with gastric lymphoma is rare. Helicobacter pylori is a common etiologic agent for both these conditions. We report a 38-year-old lady who was initially diagnosed to have gastric lymphoma and developed early gastric carcinoma on follow up. She was operated on for the carcinoma and is in complete remission since.

Abstract
The instability, rupture, and subsequent growth of holes in a thin Jeffreys-type viscoelastic film under the influence of long-range van der Waals force are investigated using both linear stability analysis and nonlinear numerical solutions. The linear stability analysis of full governing equations valid for arbitrary wave numbers shows that although fluid rheology does not influence the dominant length scale of the instability, it significantly affects the growth rate. It is shown that neglect of inertia and solvent dynamics results in a nonphysical singularity in the growth rate beyond a critical value of relaxation time. We further carry out numerical simulations of a set of long-wave, nonlinear differential equations (also derived in Rauscher et al., Eur. Phys. J. E 17, 373 (2005)) governing the evolution of the free surface. The nonlinear simulations, in their domain of validity, confirm the results of the linear analysis. Interestingly, results from nonlinear simulations further show that both for Newtonian and viscoelastic liquids, the shape and the dewetting dynamics of a hole are identical when examined in terms of a rescaled time which depends on rheological parameters. Thus, viscoelasticity of Jeffreys type merely accelerates the growth rate, without however affecting the important morphological characteristics.

Abstract
Hodgkin's disease survivors are at an increased risk of developing second malignant neoplasms including secondary bone tumors. Common secondary bone tumors are osteogenic sarcoma and fibrosarcoma. Secondary primitive neuroectodermal tumor is extremely rare in this group. We present below, a rare case of secondary PNET in an 8-year-old child with Hodgkin's disease which developed unusually early outside the radiation portal and discuss potential factors responsible for its causation.

Abstract
Lymphatic filariasis (LF) and the major soil-transmitted helminth (STH) infections are co-endemic in many countries, particularly in Asia. Control strategies for both groups of infections have increasingly focused on the use of mass chemotherapy. With the use of albendazole, there is now a tool that is common to both. However, there are also important differences in their modes of transmission and epidemiology, and, as a result, in the overall control strategies. The Global Programme for the Elimination of Lymphatic Filariasis aims to eliminate LF through time-limited mass drug administration programmes. Control activities for STH are more diffuse, aiming to piggy-back de-worming onto existing services, such as school health activities; controlling morbidity, rather than eliminating infection, is the stated goal. In order to maximize health benefits to communities that are endemic for one or both of these infections, it is vitally important that policy makers and programme managers have a clear understanding of both commonalities and differences, and implement control strategies that allocate available resources in an optimal manner.

Abstract
Advances in the management of ovarian cancer by use of aggressive surgery and effective platinum-based chemotherapy have prolonged survival; this may have resulted in an alteration of the metastatic pattern of the disease and spread to unusual sites (e.g, CNS) has become more common. Also, with the availability of more sensitive imaging techniques, these tumors are being diagnosed with increasing frequency. Intramedullary spinal cord metastasis is rare. We report one such case treated successfully with chemotherapy and radiotherapy with long-term survival.

Abstract
Rituximab has been used extensively in lymphoproliferative disorders. We evaluated the results of 64 consecutive patients treated between 2001 and 2004 at our institution. This included 54 males and 10 females. The median age was 54 years (range 17 to 85 years). One-fourth of patients were above 60 years. The histology was aggressive NHL in 35, indolent NHL in 22 and 7 cases were diagnosed as CLL. Among NHL, sixteen were in early stage (I/II) and the remaining forty-one were in advanced stage (III/IV) of disease. B symptoms were present in 47% of cases. A total of 33 were de novo cases and 31 were previously treated. Rituximab monotherapy was used in 17 cases. Rituximab was used in combination with chemotherapy in the other 47 cases. Infusional toxicity included anaphylaxis in one, hypotension in one and minor infusional reactions in four others. The patient who developed anaphylaxis required discontinuation of further Rituximab. Growth factors were used in 25 patients. Febrile neutropenia occurred in 19 patients. The overall RR (CR + PR) was 72%. One patient had stable disease and progressive disease was documented in 17 patients. A total of seven patients died, three due to progressive disease, three due to chemotherapy related toxicity and one due to an unrelated cause. We conclude that Rituximab is a valuable addition to the treatment armamentarium of lymphoproliferative disorders.

Abstract
In this study, we show that partial mitochondrial DNA (mtDNA) depletion (mitochondrial stress) induces resistance to staurosporine (STP)-mediated apoptosis in C2C12 myoblasts. MtDNA-depleted cells show a 3-4-fold increased proapoptotic proteins (Bax, BAD and Bid), markedly increased antiapoptotic Bcl-2, and reduced processing of p21 Bid to active tBid. The protein levels and also the ability to undergo STP-mediated apoptosis were restored in reverted cells containing near-normal mtDNA levels and restored mitochondrial transmembrane potential. Inhibition of apoptosis closely correlated with sequestration of Bax, Bid and BAD in the mitochondrial inner membrane, increased Bcl-2 and Bcl-X(L), and inability to process p21 Bid. These factors, together with the reduced activation of caspases 3, 9 and 8 are possible causes of mitochondrial stress-induced resistance to apoptosis. Our results suggest that a highly proliferative and invasive behavior of mtDNA-depleted C2C12 cells is related to their resistance to apoptosis.
