Epidemiology and outcome of HIV patients in Finland co-infected with tuberculosis 1998-2015.

BACKGROUND: Tuberculosis (TB) is a major cause of death in HIV patients worldwide. Here we describe the epidemiology and outcome of HIV-TB co-infections in a high-income country with low TB incidence and integrated HIV and TB therapy according to European guidelines. METHODS: This study was based on the HIV cohort of the Helsinki University Hospital which includes all HIV patients in the Helsinki region with a population of 1.5 million. Totally, 1939 HIV-positives who have been under follow-up between 1998 and 2015 were included. RESULTS: TB was diagnosed in 53 (2.7%) of the HIV-patients. The TB incidence rate was higher in injecting drug users (IRR 3.15; 95% CI 1.33-7.52) and heterosexuals (IRR 3.46; 95% CI 1.64-7.29) compared to men having sex with men. The incidence rate was also higher in those born in Sub-Saharan Africa (IRR 3.53; 95% CI 1.78-7.03) compared to those born in Finland. There was a significant reduction in the total TB incidence rate of 59% per 6-year period between 1998 and 2015 (p < 0.001). In injecting drug users there was a reduction in incidence rate from 1182 to 88 per 100,000 (p < 0.001) and in people born in Sub-Saharan Africa from 2017 to 195 per 100,000 (p < 0.001). Among the 53 HIV-TB co-infected cases, one female and 15 males died during follow up. HIV was the primary cause of death in five patients but none of the deaths were caused by TB. CONCLUSION: The incidence rate of tuberculosis among HIV-positives in Finland has been declining between 1998 and 2015. Among injecting drug users, the reduction is probably explained by harm reduction interventions and care in comprehensive care centers in Helsinki. The increased coverage of antiretroviral therapy is probably another main reason for the decline in TB incidence rates. Despite good treatment results for both HIV and TB, the all-cause mortality among Finnish males with HIV-TB was high, and common causes of death were intoxications and suicides.

Stuck in the Clinic: Vernacular Healing and Medical Anthropology in Contemporary sub-Saharan Africa.

While vernacular therapeutics had long been a topic of interest to many writing about medicine and healing in Africa, with a few exceptions most recent anthropological writings on medicine in Africa are focused on biomedicine. In this article, I trace this shift back to the turn of the millennium and the convergence of three events: the emergence of global health, the accession of the occult economies paradigm, and critiques of culturalism in medical anthropology. I argue that these three shifts led to research projects and priorities that looked different from those defined and undertaken as late as the late 1990s. While seeking to avoid the errors that could come with writing about vernacular therapeutic traditions in Africa as bounded comprehensive systems, I argue that there are empirical, political, and practical reasons why medical anthropologists may want to reconsider our collective research priorities.

Relationship between vitamin D knowledge and 25-hydroxyvitamin D levels amongst pregnant women.

BACKGROUND: Pregnant women living at northerly latitudes are at risk of suboptimal vitamin D status. There is a paucity of studies correlating knowledge, attitudes and practices of vitamin D with serum levels amongst pregnant women. We aimed to determine the prevalence of suboptimal vitamin D status in pregnant women of various ethnicities attending two Dublin maternity hospitals and to assess levels of knowledge, attitudes and practices concerning vitamin D. METHODS: We conducted a cross-sectional study of 116 pregnant women of Irish, Asian, Sub-Saharan African and Middle Eastern and North African (MENA) origin. Vitamin D status was determined by measurement of serum 25-hydroxyvitamin D (25OHD). We examined knowledge, attitudes and practices concerning vitamin D using an interview-assisted questionnaire. RESULTS: The median (interquartile range) 25OHD level was 25.9 (16.5-44.7) nmol L(-1). Using a cut-off point of <30 nmol L(-1) , the proportion at risk of deficiency was significantly higher among MENA (88%; P < 0.001) and Sub-Saharan African women (68%; P = 0.019) than Irish women (36%). Eighty-two women (71%) reported they had insufficient knowledge about vitamin D and its sources. Vitamin D containing supplement usage was the strongest predictor of 25OHD levels ≥30 nmol L(-1) (odds ratio = 18.03, 95% confidence interval = 5.7256.8, P < 0.001). CONCLUSIONS: Suboptimal vitamin D status is common in this cohort of pregnant women, especially among those of Sub-Saharan African and MENA origin. Awareness of vitamin D dietary sources is poor among all subgroups. Recommending vitamin D containing supplements may be the best strategy at present for improving vitamin D status with a need for increased vitamin D education.

Comprehensive care for sickle cell disease immigrant patients: a reproducible model achieving high adherence to minimum standards of care.

BACKGROUND: Comprehensive care and advances in clinical investigations have reduced morbidity and mortality in sickle cell disease (SCD), but only a minority of children with SCD has access to comprehensive care. In Europe the majority of patients with SCD are immigrants who present barriers in accessing the health system; therefore, new evidence-based models of comprehensive care are needed to ensure that all SCD patients receive high-quality care, overcoming patient- and health system-related barriers. We wanted to verify if addressing the specific needs of immigrant patients contributes to improving adherence. PROCEDURES: Linguistic, cultural, social issues were considered in organizing comprehensive care in 2006. Hospital's records were used to determine access from 2006 to 2010 and to compare adherence before and after 2006. RESULTS: Ninety-four patients with SCD were enrolled in comprehensive care; 94% were first generation immigrants (81% African). Age at diagnosis was higher for children born abroad vs. children born in Italy (66.08 vs 25.36 months, P < 0.005). Since 2006, children were seen at least once a year, with 100% adherence to follow-up appointments. Coverage increased from 26% to 97% for flu vaccination, from 80% to 92% for pneumococcus immunization, from 27% to 100% for Transcranial Doppler (TCD) screening (P < 0.001). Emergency Department access/patient/year and inpatient admissions/patient/year decreased from 2.3 to 0.98 and from 0.30 to 0.25, respectively (P < 0.001). CONCLUSIONS: Comprehensive care can be delivered to vulnerable groups obtaining high adherence if linguistic, cultural, social issues are addressed. This model may merit assessment in other communities where immigrants represent the majority of patients.

Genomic ancestry of North Africans supports back-to-Africa migrations.

North African populations are distinct from sub-Saharan Africans based on cultural, linguistic, and phenotypic attributes; however, the time and the extent of genetic divergence between populations north and south of the Sahara remain poorly understood. Here, we interrogate the multilayered history of North Africa by characterizing the effect of hypothesized migrations from the Near East, Europe, and sub-Saharan Africa on current genetic diversity. We present dense, genome-wide SNP genotyping array data (730,000 sites) from seven North African populations, spanning from Egypt to Morocco, and one Spanish population. We identify a gradient of likely autochthonous Maghrebi ancestry that increases from east to west across northern Africa; this ancestry is likely derived from "back-to-Africa" gene flow more than 12,000 years ago (ya), prior to the Holocene. The indigenous North African ancestry is more frequent in populations with historical Berber ethnicity. In most North African populations we also see substantial shared ancestry with the Near East, and to a lesser extent sub-Saharan Africa and Europe. To estimate the time of migration from sub-Saharan populations into North Africa, we implement a maximum likelihood dating method based on the distribution of migrant tracts. In order to first identify migrant tracts, we assign local ancestry to haplotypes using a novel, principal component-based analysis of three ancestral populations. We estimate that a migration of western African origin into Morocco began about 40 generations ago (approximately 1,200 ya); a migration of individuals with Nilotic ancestry into Egypt occurred about 25 generations ago (approximately 750 ya). Our genomic data reveal an extraordinarily complex history of migrations, involving at least five ancestral populations, into North Africa.

Association of kidney function, vitamin D deficiency, and circulating markers of mineral and bone disorders in CKD.

BACKGROUND: Vitamin D (25 hydroxyvitamin D [25(OH)D]) deficiency is common in patients with chronic kidney disease (CKD). Neither the relation of this deficiency to the decrease in glomerular filtration rate (GFR) nor the effects on CKD mineral and bone disorders (MBD) are clearly established. STUDY DESIGN: Cross-sectional analysis of baseline data from a prospective cohort, the NephroTest Study. SETTING & PARTICIPANTS: 1,026 adult patients with all-stage CKD not on dialysis therapy or receiving vitamin D supplementation. PREDICTORS: For part 1, measured GFR (mGFR) using (51)Cr-EDTA renal clearance; for part 2, 25(OH)D deficiency at <15 ng/mL. OUTCOMES & MEASUREMENTS: For part 1, 25(OH)D deficiency and several circulating MBD markers; for part 2, circulating MBD markers. RESULTS: For part 1, the prevalence of 25(OH)D deficiency was associated inversely with mGFR, ranging from 28%-51% for mGFR ≥60-<15 mL/min/1.73 m(2). It was higher in patients of African origin; those with obesity, diabetes, hypertension, macroalbuminuria, and hypoalbuminemia; and during winter. After adjusting for these factors, ORs for 25(OH)D deficiency increased from 1.4 (95% CI, 0.9-2.3) to 1.4 (95% CI, 0.9-2.1), 1.7 (95% CI, 1.1-2.7), and 1.9 (95% CI, 1.1-3.6) as mGFR decreased from 45-59 to 30-44, 15-29, and <15 (reference, ≥60) mL/min/1.73 m(2) (P for trend = 0.02). For part 2, 25(OH)D deficiency was associated with higher age-, sex-, and mGFR-adjusted ORs of ionized calcium level <1.10 mmol/L (2.6; 95% CI, 1.2-5.9), 1,25 dihydroxyvitamin D concentration <16.7 pg/mL (1.8; 95% CI, 1.3-2.4), hyperparathyroidism (1.8; 95% CI, 1.3-2.4), and serum C-terminal cross-linked collagen type I telopeptides concentration >1,000 pg/mL (1.6; 95% CI, 1.0-2.6). It was not associated with hyperphosphatemia (phosphate >1.38 mmol/L). LIMITATIONS: Cross-sectional analysis of the data prevents causal inferences. CONCLUSIONS: 25(OH)D deficiency is related independently to impaired mGFR. Both mGFR decrease and 25(OH)D deficiency are associated with abnormal levels of circulating MBD biomarkers.

Palliative care: a case study and reflections on some spiritual issues.

Being aware of notions of spirituality and ethnicity are perhaps at no time as important in nursing as at the end of a patient's life. This paper reflects on a case study of a patient receiving palliative care who was a nurse from Africa. One key reflection that arose from this case is 'what is spirituality?' How this is expressed is a dynamic process, and cannot necessarily be captured by a one-off question and answer session. The following case study highlights that what we want at the end of life, or may think we would want is not at all fixed. Therefore, nurses caring for dying patients need to be open-minded, and check regularly that the patient's chosen pathway is being followed. Also, there must be space for patients to change their minds. Tools are available and might be usefully adapted to suit individual patients' needs.

Transnational health and treatment networks: meaning, value and place in health seeking amongst southern African migrants in London.

Drawing upon research undertaken with migrants from southern Africa living in London, this paper examines the important role played by transnational health networks in influencing individual's treatment seeking decisions. As well as exploring the ways in which these networks provide important sources of help and support for people in times of ill health, the paper examines the ways in which treatments from particular places and contexts carry certain associations, meanings and values, which are in turn, considered vital in influencing health care outcomes.

Use of complementary, non-pharmacological pain reduction methods during childbirth among foreign-born and Swedish-born women.

OBJECTIVE: to investigate the association between country of origin of women and their use of complementary pain reduction methods (i.e. non-pharmacological) during childbirth in Sweden. DESIGN: cross-sectional design. SETTING: a national register-based study. PARTICIPANTS: 215,497 singleton deliveries (including the first birth of each woman during the period) of women aged 18-47 years in Sweden between 1996 and 1998, divided into 12 subgroups of countries or regions. MEASUREMENTS: the use of complementary pain reduction methods during childbirth was analysed by logistic regression, adjusting for parity, level of education, number of antenatal care visits, complications in pregnancy, complications during childbirth, use of any pharmacological methods and use of epidural/spinal analgesia during childbirth. FINDINGS: all subgroups of foreign-born women, except those from Finland, had lower odds of complementary pain reduction methods during childbirth than Swedish-born women. Women from Bosnia, Arab countries, Sub-Saharan Africa, Turkey, Iran and Asia had about 40% lower odds for use of complementary pain reduction methods during childbirth than Swedish-born women. Women who used epidural analgesia had higher odds for use of complementary pain reduction methods during childbirth than women who did not use any pharmacological methods. KEY CONCLUSION: most subgroups of foreign-born women showed lower odds for and a different pattern in the use of complementary pain reduction methods during childbirth than Swedish-born women. These findings raise questions of whether the Swedish health-care system and care providers have sufficient awareness of and insight into the socio-cultural context of giving birth.

Cryptorchidism at birth in Nice area (France) is associated with higher prenatal exposure to PCBs and DDE, as assessed by colostrum concentrations.

BACKGROUND: Since fetal exposure to anti-androgenic and/or estrogenic compounds has adverse effect on animal reproduction, such exposure could be harmful to human fetus. Data are scarce on cryptorchidism and human exposure to endocrine disruptors. METHODS: We performed a prospective case-control study to assess the incidence of cryptorchidism and fetal exposure to selected chemicals in the Nice area. One hundred and fifty-one cord bloods (67 cryptorchid, 84 tightly matched controls) and 125 colostrums (56 for cryptorchid and 69 for controls) were screened for xenobiotics, including anti-androgenic dichloro-diphenyl-trichloro-ethylene (DDE), polychlorinated biphenyls (PCBs), and dibutylphthalate (and metabolite monobutylphthalate, mBP). RESULTS: Median concentrations in colostrum were higher, although not statistically significantly, in cryptorchid versus controls. Cryptorchid boys were more likely to be classified in the most contaminated groups in colostrum for DDE, Sigma PCBs and the composite score PCB + DDE. The same trend, but again not statistically significantly was observed for mBP. Odds ratio for cryptorchidism was increased for the highest score of Sigma PCB, with a trend only for DDE and Sigma PCB + DDE versus the lowest score of those components. CONCLUSIONS: Our results support an association between congenital cryptorchidism and fetal exposure to PCBs and possibly DDE. Higher concentrations in milk could be a marker of higher exposure or for an impaired detoxification pattern in genetically predisposed individuals.

Indigenous beliefs and attitudes to AIDS precautions in a rural South African community: an empirical study.

BACKGROUND: It was recently hypothesized that indigenous belief systems might have a bearing on attitudes toward HIV/AIDS prevention in Southern Africa. PURPOSE: This article comprises the first empirical test of the hypothesis. METHODS: Participants (n = 407) lived in a remote rural area of KwaZulu Natal, South Africa, and were divided into younger (18-24 years) and older (35-45 years) cohorts. All participants completed a questionnaire measuring Attitudes to AIDS Precautions, indigenous knowledge, indigenous beliefs about ancestral protection, and indigenous beliefs about illness. RESULTS: Indigenous beliefs pertaining to health behavior emerged as multidimensional in both structure and effect. Among older participants, there were significant associations between indigenous belief measures and Attitudes to AIDS Precautions. In this group, a strong belief in ancestral protection was associated with more negative Attitudes to AIDS Precautions, whereas a strong belief in traditional explanations for illness was associated with more positive Attitudes to AIDS Precautions. The indigenous beliefs measures were not associated with Attitudes to AIDS Precautions among younger participants. CONCLUSIONS: The data lend modest support to the hypothesis that indigenous beliefs have a measurable association with attitudes to AIDS prevention, although these associations may be diminishing across generations. Further research, exploring a wider range of indigenous beliefs and focusing on actual precautionary behaviors rather than attitudes, seems merited.
