Assessment of immunity to polio among Rohingya children in Cox's Bazar, Bangladesh, 2018: A cross-sectional survey.

BACKGROUND: We performed a cross-sectional survey in April-May 2018 among Rohingya in Cox's Bazar, Bangladesh, to assess polio immunity and inform vaccination strategies. METHODS AND FINDINGS: Rohingya children aged 1-6 years (younger group) and 7-14 years (older group) were selected using multi-stage cluster sampling in makeshift settlements and simple random sampling in Nayapara registered camp. Surveyors asked parents/caregivers if the child received any oral poliovirus vaccine (OPV) in Myanmar and, for younger children, if the child received vaccine in any of the 5 campaigns delivering bivalent OPV (serotypes 1 and 3) conducted during September 2017-April 2018 in Cox's Bazar. Dried blood spot (DBS) specimens were tested for neutralizing antibodies to poliovirus types 1, 2, and 3 in 580 younger and 297 older children. Titers ≥ 1:8 were considered protective. Among 632 children (335 aged 1-6 years, 297 aged 7-14 years) enrolled in the study in makeshift settlements, 51% were male and 89% had arrived after August 9, 2017. Among 245 children (all aged 1-6 years) enrolled in the study in Nayapara, 54% were male and 10% had arrived after August 9, 2017. Among younger children, 74% in makeshift settlements and 92% in Nayapara received >3 bivalent OPV doses in campaigns. Type 1 seroprevalence was 85% (95% CI 80%-89%) among younger children and 91% (95% CI 86%-95%) among older children in makeshift settlements, and 92% (88%-95%) among younger children in Nayapara. Type 2 seroprevalence was lower among younger children than older children in makeshift settlements (74% [95% CI 68%-79%] versus 97% [95% CI 94%-99%], p < 0.001), and was 69% (95% CI 63%-74%) among younger children in Nayapara. Type 3 seroprevalence was below 75% for both age groups and areas. The limitations of this study are unknown routine immunization history and poor retention of vaccination cards. CONCLUSIONS: Younger Rohingya children had immunity gaps to all 3 polio serotypes and should be targeted by future campaigns and catch-up routine immunization. DBS collection can enhance the reliability of assessments of outbreak risk and vaccination strategy impact in emergency settings.

Increased NID1 Expression among Breast Cancer Lung Metastatic Women; A Comparative Analysis between Naive and Treated Cases.

BACKGROUND: Lungs are the second most common reported site of distant metastasis in Breast cancer after bone. Mostly the studies were conducted in cell lines and animal model. To date, there is no blood biomarker reported that could determine the breast cancer progression in terms of lung metastasis. OBJECTIVE: The aim of this study is to determine Nidogen-1 (NID1)'s mRNA and protein expressions in non-invasive blood samples of breast cancer, in early (II) and lung metastasis advanced stages (III & IV) of naive and treated groups. To determine the functional association of NID1, we employed an in silico analysis, STRING database version 11. METHODS: A total of n = 175 cases of breast cancer were recruited in our study. Real time quantitative PCR and ELISA were performed to analyze the mRNA and protein expressions of NID1 respectively. An in silico method is also used to assess NID1's interactome. Some significant patents related to this topic were also studied and discussed in this research paper. RESULTS: The results show high levels of NID1's mRNA in the naive group (Group A) as compared to treated group (Group B). Similar trend of increased NID1's protein expressions was also observed among naive and treated groups, respectively. Our results also show the significant impact of treatment on NID1's gene and protein expressions. In silico analysis has revealed the functional association of NID1 with its different interactome protein partners. CONCLUSION: The increased expression of NID1 in early to advanced naive as compared to the treated groups with lung metastasis makes it a promising marker which has pro-metastatic role in breast cancer.

Diabetes risk assessment among squatter settlements in Pakistan: A cross-sectional study.

INTRODUCTION: Diabetes mellitus (DM) has evolved as a major public health concern worldwide, as its prevalence is increasing exponentially. Pakistan now ranks seventh among the countries with the highest burden of DM. It is expected to become one of the major causes of morbidity within the next 25 years. Therefore, finding an effective way to identify individuals at risk of developing diabetes is a necessity. The Finnish Diabetes Risk Score (FINDRISC) has proved to be an effective noninvasive screening tool for identifying individuals at risk for developing diabetes. The objective of this study was to determine the frequency of individuals who are at risk for developing DM and their risk of developing DM over the next 10 years using the FINDRISC tool. METHODS: A cross-sectional survey was conducted on 241 adults. The data were collected using the FINDRISC questionnaire followed by calculation of a summated score and analysis to determine the association between the risk factors under study and the risk of developing diabetes. RESULTS: Out of 241 study participants, 137 (56.8%) were men and 104 (43.1%) were women. Our study showed that 129 (53.5%) participants had low risk, 68 (28.2%) had slightly elevated risk, 27 (11.2%) had moderate risk and 17 (7%) had high risk of developing DM. CONCLUSION: The general population should be educated about the importance of healthy lifestyle, with special emphases on maintaining an ideal body mass index and a low-risk waist circumference, along with daily fruit and vegetable intake and physical activity of at least 30 min/day.

Assessment of fertility control efforts in a selected area of Karachi, Pakistan.

AIMS: To investigate the impact of fertility control efforts on reducing fertility and to study the contributory role of fertility inhibiting factors viz, age of the marriage, breast feeding and post-partum amenorrhea, abortion and use of contraceptives in selected area in Karachi, Pakistan. The aim was to estimate the gap between knowledge of contraceptives and its practice i.e. KAP-GAP as well as to determine the level of unmet need in the PIB colony in Karachi. DATA SOURCE: A sample survey was conducted in PIB colony in Karachi from October 2005 to November 2005 by interviewing 340 married women in reproductive ages. The data was tabulated and John Bongaarts technique was used to analyse the success of fertility control efforts in the selected area. RESULTS: Of the total of 340 respondents, 38% were currently using contraceptive methods with 26% using OCP's and 12% were condom users. A slight reduction in total fertility (TFR) was noticed. CONCLUSION: The population policy of Pakistan envisages achieving population stabilization in 2020 by reducing the annual rate of population growth from 1.9% to 1.3% and TFR at 2.1. This target requires strenuous efforts to make the concept of small family an accepted milieu through an eagerly designed communication and education campaign. Concentration on proximate determinants of fertility particularly breast feeding and prolonging birth interval will not generate opposition from the community because these concepts are in accordance with Islamic injunctions and teachings.
