On the spread of spatial attention in touch: Evidence from event-related brain potentials.

To investigate the distribution of tactile spatial attention near the current attentional focus, participants were cued to attend to one of four body locations (hand or shoulder on the left or right side) to respond to infrequent tactile targets. In this Narrow attention task, effects of spatial attention on the ERPs elicited by tactile stimuli delivered to the hands were compared as a function of the distance from the attentional focus (Focus on the hand vs. Focus on the shoulder).

"I don't know when he will be back": life-changing events challenge the community ART Group model- a qualitative research study, Tete, Mozambique.

Background: Since 2008 in Mozambique, patients stable on antiretroviral therapy (ART) can join Community ART Groups (CAG), peer groups in which members are involved in adherence support and community ART delivery. More than 10 years after the implementation of the first CAGs, we study how changes in circumstance and daily life events of CAG members have affected the CAG dynamic.

Methods: A qualitative study using individual in-depth interviews (27) and focus group discussions (8) with CAG members and health care providers was carried out in Tete province, rural Mozambique.

Slipping through the cracks: a qualitative study to explore pathways of HIV care and treatment amongst hospitalised patients with advanced HIV in Kenya and the Democratic Republic of the Congo.

Advanced HIV causes substantial mortality in sub-Saharan Africa despite widespread antiretroviral therapy coverage. This paper explores pathways of care amongst hospitalised patients with advanced HIV in rural Kenya and urban Democratic Republic of the Congo, with a view to understanding their care-seeking trajectories and poor health outcomes. Thirty in-depth interviews were conducted with hospitalised patients with advanced HIV who had previously initiated first-line antiretroviral therapy, covering their experiences of living with HIV and care-seeking.

"I try the one that they say is good." - factors influencing choice of health care provider and pathways to diabetes care for Syrian refugees in Lebanon.

Background: Navigating health systems in host countries can be a challenge for refugees, particularly in a multi-provider system such as Lebanon. Syrian refugees in Lebanon face a high burden of Non-Communicable Diseases (NCDs) including diabetes mellitus. Evidence on how refugees navigate the health system is essential to improve provision of NCD services.

"It's a secret between us": a qualitative study on children and care-giver experiences of HIV disclosure in Kinshasa, Democratic Republic of Congo.

Background: It is estimated that 64,000 children under 15 years of age are living with HIV in the Democratic Republic of Congo (DRC). Non-disclosure - in which the child is not informed about their HIV status - is likely to be associated with poor outcomes during adolescence including increased risk of poor adherence and retention, and treatment failure. Disclosing a child's HIV status to them can be a difficult process for care-givers and children, and in this qualitative study we explored child and care-giver experiences of the process of disclosing, including reasons for delay.

Nitrate supply and uptake in the Atlantic Arctic sea ice zone: seasonal cycle, mechanisms and drivers.

Nutrient supply to the surface ocean is a key factor regulating primary production in the Arctic Ocean under current conditions and with ongoing warming and sea ice losses. Here we present seasonal nitrate concentration and hydrographic data from two oceanographic moorings on the northern Barents shelf between autumn 2017 and summer 2018. The eastern mooring was sea ice-covered to varying degrees during autumn, winter and spring, and was characterized by more Arctic-like oceanographic conditions, while the western mooring was ice-free year-round and showed a greater influence of Atlantic water masses.

'Only twice a year': a qualitative exploration of 6-month antiretroviral treatment refills in adherence clubs for people living with HIV in Khayelitsha, South Africa.

Objective: Longer intervals between routine clinic visits and medication refills are part of patient-centred, differentiated service delivery (DSD). They have been shown to improve patient outcomes as well as optimise health services-vital as 'universal test-and-treat' targets increase numbers of HIV patients on antiretroviral treatment (ART). This qualitative study explored patient, healthcare worker and key informant experiences and perceptions of extending ART refills to 6 months in adherence clubs in Khayelitsha, South Africa.

Knowledge transmission, peer support, behaviour change and satisfaction in post Natal clubs in Khayelitsha, South Africa: a qualitative study.

Background: The Post Natal Club (PNC) model assures comprehensive care, including HIV and Maternal and Child Health care, for postpartum women living with HIV and their infants during an 18-month postnatal period. The PNC model was launched in 2016 in Town Two Clinic, a primary health care facility in Khayelitsha, South Africa. This qualitative research study aims to understand how participation in PNCs affected knowledge transmission, peer support, behaviour change and satisfaction with the care provided.

Access to health services for men who have sex with men and transgender women in Beira, Mozambique: A qualitative study.

Objectives: HIV prevalence and incidence are higher among key populations including Men who have Sex with Men (MSM) and transgender women in low and middle income countries, when compared to the general population. Despite World Health Organisation guidelines on the provision of services to key populations recommending an evidence-based, culturally relevant and rights-based approach, uptake of HIV services in many resource-limited and rights-constrained settings remains low. Médecins Sans Frontières (MSF) has been offering health services for MSM and transgender women in Beira, Mozambique since 2014 using a peer-educator driven model, but uptake of services has not been as high as expected.

Perceptions and Health-Seeking Behaviour for Mental Illness Among Syrian Refugees and Lebanese Community Members in Wadi Khaled, North Lebanon: A Qualitative Study.

This is a qualitative exploration of the perceptions of mental health (MH) and their influence on health-seeking behaviour among Syrian refugees and the Lebanese population in Wadi Khaled, a rural area of Lebanon bordering Syria. Eight focus group discussions and eight key informant interviews were conducted with male and female Syrian refugees and Lebanese community members from March to April 2018. MH illness was associated with stigma, shame and fear among both populations.

'When you welcome well, you vaccinate well': a qualitative study on improving vaccination coverage in urban settings in Conakry, Republic of Guinea.

Background: Recurrent measles outbreaks followed by mass vaccination campaigns (MVCs) occur in urban settings in sub-Saharan countries. An understanding of the reasons for this is needed to improve future vaccination strategies. The 2017 measles outbreak in Guinea provided an opportunity to qualitatively explore suboptimal vaccination coverage within an MVC among participants through their perceptions, experiences and challenges.

"With every passing day I feel like a candle, melting little by little." experiences of long-term displacement amongst Syrian refugees in Shatila, Lebanon.

Background: Long term displacement and exposure to challenging living conditions can influence family dynamics; gender roles; violence at home and in the community and mental well-being. This qualitative study explores these issues as perceived by Syrian refugees who have been living in Shatila, a Palestinian camp in South Beirut, Lebanon, for at least 2 years.

Methods: Twenty eight in-depth interviews with men and women were conducted between February and June 2018.

'I treat it but I don't know what this disease is': a qualitative study on noma (cancrum oris) and traditional healing in northwest Nigeria.

Background: Noma, a neglected disease mostly affecting children, with a 90% mortality rate if untreated, is an orofacial gangrene that disintegrates the tissues of the face in <1 wk. Noma can become inactive with early stage antibiotic treatment. Traditional healers, known as mai maganin gargajiya in Hausa, play an important role in the health system and provide care to noma patients.

In island containment: a qualitative exploration of social support systems among asylum seekers in a mental health care programme on Lesvos Island, Greece.

Background: Social support is a core determinant of health and plays a key role in the healing process of people with mental health problems and those who have been exposed to torture or other traumatic events. At the same time, social support is particularly challenging to build in such populations, as self-isolation and social withdrawal are common consequences of traumatic incidents. Defining social support is also challenging as there is no globally adequate definition.

Patient experiences of ART adherence clubs in Khayelitsha and Gugulethu, Cape Town, South Africa: A qualitative study.

Background: Globally, 37 million people are in need of lifelong antiretroviral treatment (ART). With the continual increase in the number of people living with HIV starting ART and the need for life-long retention and adherence, increasing attention is being paid to differentiated service delivery (DSD), such as adherence clubs. Adherence clubs are groups of 25-30 stable ART patients who meet five times per year at their clinic or a community location and are facilitated by a lay health-care worker who distributes pre-packed ART.

"I take my pills every day, but then it goes up, goes down. I don't know what's going on": Perceptions of HIV virological failure in a rural context in Mozambique. A qualitative research study.

Background: HIV prevalence in Mozambique is estimated to be 13.2%. Routine viral load for HIV monitoring was first implemented in the rural area of Tete in 2014.

Xpert negative means no TB: A mixed-methods study into early implementation of Xpert in Puducherry, India.

Introduction: Xpert MTB/RIF was implemented in 2016 as the initial diagnostic test for extrapulmonary, pediatric, and human immunodeficiency virus-associated tuberculosis (TB) and as an add-on test for sputum microscopy-negative patients under Revised National TB Control Programme, Puducherry, India. We intended to study the change in TB case notification rates (CNRs) after 2015 and explore the enablers and barriers for implementation of Xpert.

Materials And Methods: Sequential mixed-methods study, quantitative phase followed by a descriptive qualitative phase (key informant interviews with healthcare providers in the program).

Patient and health-care worker experiences of an HIV viral load intervention using SMS: A qualitative study.

Background: Mobile Health or mHealth interventions, including Short Message Service (SMS), can help increase access to care, enhance the efficiency of health service delivery and improve diagnosis and treatment for HIV. Text messaging, or SMS, allows for the low cost transmission of information, and has been used to send appointment reminders, information about HIV counselling and treatment, messages to encourage adherence and information on nutrition and side-effects. HIV Viral Load (VL) monitoring is recommended by the WHO and has been progressively adopted in many settings.

"Even if she's really sick at home, she will pretend that everything is fine.": Delays in seeking care and treatment for advanced HIV disease in Kinshasa, Democratic Republic of Congo.

Introduction: HIV prevalence in the Democratic Republic of Congo (DRC) is estimated to be 1.2%, and access to HIV testing and treatment remains low across the country. Despite advances in treatment, HIV continues to be one of the main reasons for hospitalisation and death in low- and middle-income countries, including DRC, but the reasons why people delay seeking health-care when they are extremely sick remain little understood.

"Small small interventions, big big roles"- a qualitative study of patient, care-giver and health-care worker experiences of a palliative care programme in Kerala, India.

Background: Home-based palliative care is an essential resource for many communities. We conducted a qualitative study to explore perceptions of a home-based palliative care programme in Kerala, India, from the perspective of patients, their care-givers and the doctors, nurses and volunteers running the intervention.

Methods: A descriptive qualitative study was carried out.

"Life continues": Patient, health care and community care workers perspectives on self-administered treatment for rifampicin-resistant tuberculosis in Khayelitsha, South Africa.

Background: Self-administered treatment (SAT), a differentiated model of care for rifampicin-resistant tuberculosis (RR-TB), might address adherence challenges faced by patients and health care systems. This study explored patient, health-care worker (HCW) and community care worker (CCW) perspectives on a SAT pilot programme in South Africa, in which patients were given medication to take at home with the optional support of a CCW.

Methods: We conducted a mixed-methods study from July 2016-June 2017.

'I didn't know so many people cared about me': support for patients who interrupt drug-resistant TB treatment.

Setting: Early interventions for patients who interrupt their treatment for drug-resistant tuberculosis (DR-TB) are rarely reported and assessed. A novel, patient-centred intervention for patients at risk of loss to follow-up (LTFU) from DR-TB treatment was implemented in Khayelitsha, South Africa, in September 2013.

Objective: To explore the experiences and perceptions of patients, key support persons, health care workers (HCWs) and programme managers of a patient-centred model.

"I feel like I am less than other people": Health-related vulnerabilities of male migrants travelling alone on their journey to Europe.

During 2015 and 2016, an unprecedented flow of approximately 800,000 migrants coming from Turkey towards Western Europe crossed the Balkans. Male migrants are perceived as being less vulnerable compared to other migrants and they are not given priority in service and support provision. This qualitative study examines the self-perceived vulnerabilities of male migrants travelling alone along the Balkan route to Europe.

Conflict and tuberculosis in Sudan: a 10-year review of the National Tuberculosis Programme, 2004-2014.

Background: Sudan is a fragile developing country, with a low expenditure on health. It has been subjected to ongoing conflicts ever since 1956, with the Darfur crisis peaking in 2004. The conflict, in combination with the weak infrastructure, can lead to poor access to healthcare.
