| 3 | Pay-it-forward gonorrhea and chlamydia testing among men who have sex with men in China:a study protocol for a three-arm cluster randomized controlled trial显示文摘Background:Gonorrhea and chlamydia testing rates are poor among Chinese men who have sex with men(MSM).A quasi-experimental study suggested that a pay-it-forward strategy increased dual gonorrhea/chlamydia testing among MSM.Pay-it-forward offers an individual a gift(e.g.,a free test)and then asks the same person if they would like to give a gift to another person.This article reports the protocol of a randomized controlled trial to evaluate dual gonorrhea/chlamydia test uptake and other outcomes among MSM in three arms-a pay-it-forward arm,a pay-what-you-want arm,and a standard of care arm.Methods:Three hundred MSM will be recruited at three HIV testing sites in Guangzhou and Beijing.Testing sites include two hospital-based MSM sexually transmitted diseases clinics and one MSM community-based organization.Eligible participants will be born biologically male,aged 16 years or older,reporting previous anal sex with another man,having never participated in the pay-it-forward program,without previous gonorrhea and chlamydia testing in the past 12 months,and residing in China.Following a cluster randomized design,every cluster of ten participants will be randomly allocated into one of three arms:(1)a pay-it-forward arm in which men are offered free gonorrhea and chlamydia testing and then asked whether they would like to donate('pay it forward')toward testing for future testers;(2)a pay-what-you-want arm in which men are offered free testing and told to decide how much to pay after receiving the test;(3)a standard of care arm in which men can pay the full price for dual gonorrhoea and chlamydia testing.The primary outcome is dual gonorrhoea/chlamydia testing as verified by administrative records.Secondary outcomes include incremental cost per test,incremental cost per diagnosis,community connectedness,and social cohesion.Primary outcome will be calculated for each arm using intention-to-treat and compared using one-sided 95%confidence intervals with a margin of 20%increase defined as superiority.Discussion:This study will examine the pay-it-forward strategy in comparison to the standard of care in improving test uptake for gonorrhea and chlamydia.We will leverage the cluster randomized controlled trial to provide scientific evidence on the potential effect of pay-it-forward.Findings from this study will shed light on novel intervention methods for increasing preventive health service utilization and innovate ways to finance it among communities.Trial registration:ClinicalTrials.gov,NCT03741725.Registered on 12 November 2018. | Tiange P.Zhang Fan Yang Weiming Tang Marcus Alexander Laura Forastiere Navin Kumar Katherine Li Fei Zou Ligang Yang Guodong Mi Yehua Wang Wenting Huang Amy Lee Weizan Zhu Peter Vickerman Dan Wu Bin Yang Nicholas A.Christakis Joseph D.Tucker | 2019 | Infectious Diseases of Poverty2019，8，4： | 1 |

| 5 | MOLECULAR DYNAMICS SIMULATION OF POLYMER/CARBON NANOTUBE COMPOSITES显示文摘In this paper, we present classical molecular dynamics(MD) simulations of model polymer/CNT composites constructed by embedding a single wall(10,10) CNT into two different amorphous polymer matrices: poly(methyl methacrylate) and poly{(m-phenylene-vinylene)-co-[(2,5-dioctoxy-p-phenylene) vinylene]}, respectively, with different volume fractions. The simulation results support the idea that it is possible to use CNTs to mechanically reinforce an appropriate polymer matrix, especially in the longitudinal direction of the nanotube. The comparison of the simulation results with the macroscopic rule-of-mixtures for composite systems showed that for strong interfacial interactions, there can be large deviations of the results from the rule-ofmixtures. In order to verify this study, results obtained have been compared with those given by Elliott and Han(2007). | Sumit Sharma Rakesh Chandra Pramod Kumar Navin Kumar | 2015 | Acta Mechanica Solida Sinica2015，28，4： | 1 |
| 6 | Prevalence of anxiety among gestational diabetes mellitus patients: A systematic review and meta-analysis显示文摘BACKGROUND A diagnosis of gestational diabetes mellitus(GDM)negatively influences maternal mental health.There is a lack of systematic review and meta-analysis on prevalence of anxiety among GDM women.AIM To pool data from existing literature to determine the pooled estimates for the prevalence of anxiety among women diagnosed with GDM.METHODS We searched multiple databases including MEDLINE,Cinahl,PubMed and Scopus to identify studies published up to 31 October 2019 with data on the prevalence of anxiety among women diagnosed with GDM.Data were extracted from published reports.Estimates were pooled using random-effects metaanalyses.RESULTS We reviewed 19 abstracts,retrieved 10 articles and included three studies incorporating 12744 GDM women from three countries.The pooled prevalence of anxiety was 29.5%(95%CI:6.9,52.0)among GDM women.CONCLUSION Prevalence of anxiety among GDM women was high.We suggest that epidemiological studies on anxiety should be conducted urgently as it merits clinical attention.In addition,it is important to identify factors associated with anxiety among women diagnosed with GDM. | Kai Wei Lee Hong Chuan Loh Seng Choi Chong Siew Mooi Ching Navin Kumar Devaraj Maiza Tusimin Habibah Abdul Hamid Fan Kee Hoo | 2020 | World Journal of Meta-Analysis2020，8，3： | 1 |
| 7 | Optimization of substrate ratio for beer production from finger millet and barley显示文摘Seventeen designed experiments were conducted in three steps(malting,brewing and fermentation)to produce beer from barley,finger millet and the combination of both.Effects of independent variables with three levels for each i.e.blend ratios of grains(100:0,50:50,0:100),kilning temperature(50℃,70℃,90℃)and malted grain to water ratios(1:3,1:5,1:7)were investigated on product quality.The results of the study indicated that all the independent parameters i.e.blend ratio,kilning temperature and slurry ratio affected the responses(pH,colour,bitterness and alcohol content)significantly.Optimum values of parameters,from the simultaneous optimization done using Design Expert 8.0.6.1 software,for beer production,were found to be 68:32 blend ratio,50℃ kilning temperature and 1:7 slurry ratio.The model F-value was found to be highly significant at 1% level of significance for all the responses.All the responses could be predicted by fitting the second order mathematical model and adequacy checked by R^(2). | Sanjay Kumar Anupama Singh Navin Chandra Shahi Khan Chand Kopal Gupta | 2015 | International Journal of Agricultural and Biological Engineering2015，8，2： | 0 |
| 8 | Electrospun Aligned PCL/Gelatin Scaffolds Mimicking the Skin ECM for Effective Antimicrobial Wound Dressings显示文摘Bacterial infections and multidrug-resistant bacteria are major health burdens in wound care.Biocompatible antimicrobial agents,e.g.,ε-polylysine(ε-PL),provide a broad spectrum of antibacterial properties and support dermal cell growth.Here,ε-PL was incorporated into polycaprolactone(PCL)/gelatin electrospun scaffolds collected at varying rotation speeds.Then,the samples were crosslinked using dopamine hydrochloride to provide highly proliferative dressings with broad antimicrobial activity.The morphological study showed that the electrospun wound dressings were smooth,continuous,and bead-free,with a mean diameter ranging from 267±7 to 331±8 nm for all random and aligned nanofibers.The fiber alignment of the electrospun PCL/gelatin scaffolds improved their tensile strength and modulus.Moreover,nanofiber mats are highly hydro-philic,which is crucial for an efficient wound dressing.The samples also demonstrated high antimicrobial properties against common wound bacterial strains,including methicillin-resistant Staphylococcus aureus(MRSA),Staphylococcus aureus(SA),Escherichia coli(EC),Acinetobacter baumannii(AB),and Pseudomonas aeruginosa(PA).Mammalian cell prolifera-tion and morphology assays involving primary human dermal fibroblasts(hDFs)and immortalized keratinocytes(HaCaT)showed excellent biocompatibility of the electrospun mats and remarkably aligned mats.Furthermore,aligned mats showed more cell migration than randomly oriented mats,which is desirable for more efficient wound healing.Therefore,it can be concluded that aligned PCL/gelatin mats containingε-PL are promising for potential use in wound dressings. | Erfan Rezvani Ghomi Rajamani Lakshminarayanan Vijila Chellappan Navin Kumar Verma Amutha Chinnappan Rasoul Esmaeely Neisiany Kottaiswamy Amuthavalli Zhi Sheng Poh Brandon Han Siang Wong Nileshkumar Dubey Roger Narayan Seeram Ramakrishna | 2023 | Advanced Fiber Materials2023，5，1： | 0 |

| 10 | Prevalence,awareness and control of hypertension in Malaysia from 1980-2018:A systematic review and meta-analysis显示文摘BACKGROUND Hypertension is a common public health problem worldwide and is a well-known risk factor for increased risk of cardiovascular diseases,contributing to high morbidity and mortality.However,there has been no systematic review and meta-analysis of a multiethnic population such as that of Malaysia.AIM To determine the trend in prevalence,awareness and control rate of hypertension in Malaysia.METHODS Systematic searches were conducted in six databases(PubMed,Scopus,Ovid,CINAHL,Malaysian Medical Repository and Malaysia Citation Index)for articles published between 1980 and 2018.Two authors reviewed the studies and performed quality assessment and data extraction independently.Pooled estimates of hypertension prevalence,awareness and control rate were calculated using the DerSimonian-Laird random-effects model.Subgroup and sensitivity analyses were performed.RESULTS We included 56 studies involving a total of 241796 participants.The overall pooled prevalence of hypertension aged≥18 years was 29.7%.The prevalence of hypertension was the lowest in the 1980s(16.2%,95%confidence interval(CI):13.4,19.0),increasing up to 36.8%(95%CI:6.1,67.5)in the 1990s,then decreasing to 28.7%(95%CI:21.7,35.8)in the 2000s and 26.8%(95%CI:21.3,32.3)in the 2010s.The prevalence of awareness was 51.4%(95%CI:46.6,56.3),while 33.3%(95%CI:28.4,38.2)of those on treatment had achieved control of their blood pressure.CONCLUSION In Malaysia,three in ten adults aged≥18 years have hypertension,while four in ten adults aged≥30 years have hypertension.Five out of ten people are aware of their hypertension status and only one-third of those under treatment achieved control of their hypertension.Concerted efforts by policymakers and healthcare professionals to improve awareness and control of hypertension should be of high priority. | Man Jun Soo Zhen Yee Chow Siew Mooi Ching Chun Han Tan Kai Wei Lee Navin Kumar Devaraj Hani Syahida Salim Vasudevan Ramachandran Poh Ying Lim Dhashani Sivaratnam Fan Kee Hoo Ai Theng Cheong Yook Chin Chia | 2020 | World Journal of Meta-Analysis2020，8，4： | 0 |
| 11 | Cytoreductive surgery with hyperthermic thoracoabdominal chemotherapy in stage Ⅳ ovarian cancer - a technical description显示文摘Systemic chemotherapy for peritoneal disease in ovarian carcinoma is associated with a recurrence rate of more than 75%,and most of the cases are confined to the peritoneal cavity.The propensity of locoregional treatment failure has paved the way for the discovery of cytoreductive surgery with intra-cavitary chemotherapy.Cytoreductive surgery(CRS)is the present-day treatment modality for a variety of peritoneal carcinomatosis including ovarian cancer,and multi-visceral resection is critical for completion of CRS.In cases of diaphragmatic infiltration by tumor deposits,partial resection leads to a diaphragmatic rent,which can be used for the perfusion of chemotherapeutic drugs into the pleural cavity.Disease transmission from the peritoneal to pleural cavity is a poor prognostic factor however.Hence,intrathoracic hyperthermic chemotherapy may be a reasonable treatment option for ovarian carcinoma with malignant pleural effusion or pleural deposits.Hyperthermic intraperitoneal chemotherapy(HIPEC)is added to the treatment plan in cases of complete CRS but this is a technically demanding procedure.Therefore,performing hyperthermic intrathoracic chemotherapy on top of CRS and HIPEC may be even more complicated for such advanced cancers.The technique of combining HIPEC and hyperthermic intrathoracic chemotherapy is also commonly known as hyperthermic thoracoabdominal chemotherapy(HITAC).The perioperative morbidity and mortality may be remarkably high in such scenarios.We describe our CRS technique with HITAC,which was performed in three FIGO stage IVA ovarian carcinoma patients with metastatic pleural effusion after complete CRS.The patients were retrospectively identified from a prospectively maintained database.All had partial diaphragmatic resection followed by HITAC as part of CRS treatment.Surgical techniques are outlined along with accompanying intra-operative images.Patient demographics,clinical and follow-up details were also described briefly.No comparative analysis with control patients was done.Adjustments in chemotherapy dose are not mandatory for HITAC.Of three patients,one had intrathoracic recurrence on followup;no mortality was recorded HITAC is a complex and potentially harmful procedure whose toxicity profile is still poorly known.Morbidity was not life-threatening and survival was acceptable. | Mukur Dipi Ray Raghuram Kuppusamy Navin Kumar Rakesh Garg | 2020 | Journal of Cancer Metastasis and Treatment2020，6，1： | 0 |
