n to providing screening services. Furthermore, cervical screening service should be integrated to the routine care and treatment, so that HIV-positive women can get counseling services in every clinical contact.
The uptake of cervical cancer screening among HIV-positive women in Ethiopia was low. The findings of this study suggest the need to improve the existing national strategies of cervical cancer screening so as to strengthen reproductive health education and promotion, in addition to providing screening services. Furthermore, cervical screening service should be integrated to the routine care and treatment, so that HIV-positive women can get counseling services in every clinical contact.
To investigate the function and morphology of meibomian glands (MG) in night shift medical staff (MS).

Sixty-two eyes of 31 patients in the MS group and 59 eyes of 31 patients in the control group were consecutively enrolled. All participants completed Ocular Surface Disease Index (OSDI) and Standard Patient Dry Eye Evaluation (SPEED) questionnaires for dry eye severity, as well as Schirmer I and tear break-up time (TBUT) tests. LipiView® II Ocular Surface Interferometer was used for lipid layer thickness (LLT), MG dropout, and partial blink (PB) rate tests. MG expression was measured with an MG evaluator.

The OSDI score in the MS group was 22.39 ± 13.42, which was significantly higher than that in the control group (9.87 ± 6.64
 = -3.997,

 = -4.766,
=0.001). There was no significant difference in Schirmer I test between the MS group and control group (
 = -1.346,
=0.178). TBUT in MS group was significantly shorter than that in the control group (
 = -5.201,

One assay, used by many immunologists, employs 2-(N-(7-Nitrobenz-2-oxa-1,3-diazol-4-yl)Amino)-2-Deoxyglucose (2-NBDG), a fluorescent analogue of 2-deoxyglucose (2DG), as a substrate for glucose transporters. This molecule has been validated as a substrate for the glucose transporter Glut2 (Slc2a2) in mammalian cells but 2-NDBG selectivity for the glucose transporters expressed by T cells, Glut1 (Slc2a1) and Glut3 (Slc2a3), has never been explored. Nor has the possibility that 2-NBDG might bind to T cells that do not express glucose transporters been assessed. In this technical commentary we interrogate the specificity of 2-NBBG labelling as a readout for glucose transport in T lymphocytes. We compare flow cytometric 2-NBDG staining against well validated radiolabelled glucose transport assays in murine T cells. Our data show there can be a large discordance between glucose transport capacity and 2-NBDG labelling in T cells. We also find that 2-NBDG uptake into murine T cells is not inhibited by competitive substrates or facilitative glucose transporter inhibitors, nor can 2-NBDG competitively block glucose uptake in T cells. Collectively, these data argue that 2-NBDG uptake alone is not a reliable tool for the assessment of cellular glucose transport capacity.
The prevalence and appearance of sesamoid bones in the foot vary considerably among different populations and ethnic groups. We sought to evaluate the prevalence and distribution patterns of foot sesamoid bones among Omani patients referred for radiological investigation.

We conducted a retrospective study among patients who had been referred for foot X-ray from January to December 2018. We used the chi-square test to determine the gender and age influence on the prevalence of sesamoid bones, and the Spearman's correlation coefficient to assess the coincidence of specific distributions of sesamoid bones at the metatarsophalangeal (MTP) joints.

A total of 774 foot radiographs composed of 442 right foot radiographs and 332 left foot radiographs were reviewed for the presence of sesamoid bones at MTP and interphalangeal (IP) joints of the foot. We observed a high prevalence rate of sesamoid bones at the fifth MTP joint (13.7%), and first IP of the great toe (9.9%). There were nine distinctive patterns of sesamoid bones. The coincidence of sesamoid bones at two or more MTP joints was 14.6%, with a high prevalence rate at first and fifth MTP joints (10.3%). Moreover, the prevalence rate of sesamoid bones increased with increasing age at the fifth MTP joint.

The prevalence of sesamoid bones in the foot is considerably high in Omani subjects and needs further prospective studies. Meanwhile, our findings could be helpful for clinicians to consider ailments of sesamoid bones during differential diagnosis in Omani patients who present with foot pain and discomfort.

The incidence of sports-related sudden cardiac arrest (SrSCA) in sub-Saharan Africa is unknown.

To determine the incidence of sudden cardiac arrest (SCA) in non-competitive athletes in an urban population of Cameroon, a country in sub-Saharan Africa.

Two study populations in Cameroon were used. A 12-month, multisource surveillance system of 86 189 inhabitants over 12 years old recorded all deaths in two administrative districts of Douala City. All fields of sports, emergency medical service, local medical examiners and district hospital mortuaries were surveyed. Two blinded cardiologists used a verbal autopsy protocol to determine the cause of death. SCA was identified for all deaths occurring within 1 hour of onset of symptoms. A cross-sectional study was conducted among 793 persons in Yaoundé City, which is the second study population aimed at determining the proportion of people who are physically active.

The mean age in the cross-sectional study was 27.3±10.7, with more men (56.2%). The cross-sectional study showed that 69.0% (95% CI 65.8 to 72.2) of the population could be considered to have at least 3 hours of physical activity per week. The surveillance found that among 288 all-cause deaths, 27 (9.4%) were due to SCA. One SrSCA was registered in a 35-year-old woman while running. Merging both sources revealed an SrSCA incidence of 1.7 (95% CI 0.2 to 12.0) cases per 100 000 athletes per year.

This pioneer study reports the incidence estimates of SrSCA in a sub-Saharan African general population and should be regarded as a first step to a big problem.

Microfluidics offers an invaluable tool to precisely stimulate, manipulate, and analyze the tissue microenvironment in live tissues and engineer mass transport around and into small tissue volumes. Such control is critical in clinical studies, especially where tissue samples are scarce, in analytical sensors, where testing smaller amounts of analytes results in faster, more portable sensors, and in biological experiments, where accurate control of the cellular microenvironment is needed. Microfluidics also provides inexpensive multiplexing strategies to address the pressing need to test large quantities of drugs and reagents on a single biopsy specimen, increasing testing accuracy, relevance, and speed while reducing overall diagnostic cost. Here, we review the use of microfluidics to study the physiology and pathophysiology of intact live tissues at sub-millimeter scales. We categorize uses as either in vitro studies - where a piece of an organism must be excised and introduced into the microfluidic device - or in vivo studies - where whole organisms are small enough to be introduced into microchannels or where a microfluidic device is interfaced with a live tissue surface (e.g. the skin or inside an internal organ or tumor) that forms part of an animal larger than the device. These microfluidic systems promise to deliver functional measurements obtained directly on intact tissue - such as the response of tissue to drugs or the analysis of tissue secretions - that cannot be obtained otherwise.Proposals for allocating scarce lifesaving resources in the face of the Covid-19 pandemic have aligned in some ways and conflicted in others. This paper attempts a kind of priority setting in addressing these conflicts. In the first part, we identify points on which we do not believe that reasonable people should differ-even if they do. These are (i) the inadequacy of traditional clinical ethics to address priority-setting in a pandemic; (ii) the relevance of saving lives; (iii) the flaws of first-come, first-served allocation; (iv) the relevance of post-episode survival; (v) the difference between age and other factors that affect life-expectancy; and (vi) the need to avoid quality-of-life judgments. In the second part, we lay out some positions on which reasonable people can and do differ. These include (i) conflicts between maximizing benefits and priority to the worst off; (ii) role-based priority; and (iii) whether patients' existing lifesaving resources should be subject to redistribution.
