    Information on drivers of dispersal is critical for wildlife conservation but is rare for long-lived marine mammal species with large geographic ranges. We fit multi-state mark-recapture models to resighting data of 369 known-aged Steller sea lion (Eumetopias jubatus) females marked as pups on their natal rookeries in southeastern Alaska from 1994-2005 and monitored from 2001-15. We estimated probabilities of females being first observed parous at their natal site (natal philopatry), and of not moving breeding sites among years (breeding philopatry) at large (> 400 km, all five rookeries in southeastern Alaska) and small (lions.

We estimated probabilities of females being first observed parous at their natal site (natal philopatry, and of not moving breeding sites among years (breeding philopatry at large (> 400 km, all five rookeries in southeastern Alaska and small (< 4 km, all islands within the largest rookery, Forrester Island Complex, F spatial scales. At the rookery scale, natal philopatry was moderately high (0.776-0.859 for most rookeries and breeding philopatry was nearly 1, with < 3% of females switching breeding rookeries between years. At more populous islands at F, natal philopatry was 0.500-0.684 versus 0.295-0.437 at less populous islands, and breeding philopatry was 0.919-0.926 versus 0.604-0.858. At both spatial scales, the probability of pupping at a non-natal site increased with population size of, and declined with distance from, the destination site. Natal philopatry of < 1 would increase gene flow, improve population resilience, and promote population recovery after decline in a heterogeneous environment. Very high breeding philopatry suggests that familiarity with neighboring females and knowledge of the breeding site (the topography of pupping sites and nearby foraging locations may be a critical component to reproductive strategies of sea lions.

    1. We used up to 34 years of capture-recapture data from about 22,100 new releases of day-old female ducklings and multistate modelling to test predictions about the influence of environmental, habitat and management factors on natal dispersal probability of three species of ducks within the Engure Marsh, Latvia. 2. The mean natal dispersal distances were very similar (c . 0?6-0?7 km) for all three species and were on average 2?7 times greater than breeding dispersal distances recorded within the same study system. 3. We were unable to confirm the kinship hypothesis and found no evidence that young first-nesting females nested closer to their relatives (either mother or sister) than to the natal nest. 4. Young female northern shovelers, like adults, moved from small islands to the large island when water level was high and vice versa when water level was low before the construction of elevated small islands. Movement probabilities between the two strata were much higher for young shovelers than adults, suggesting that young birds had not yet developed strong fidelity to the natal site. Movements of young female tufted ducks, unlike those of shovelers, were not dependent on water level fluctuations and reflected substantial flexibility in choice of first nesting sites. 5. Data for young birds supported our earlier conclusion that common pochard nesting habitats in black-headed gull colonies were saturated during the entire study period. Young females, like the two adult age groups, moved into and out of colonies with similar probability. Fidelity probability of female pochards to each stratum increased with age, being the lowest (0?62) for young (DK) females, intermediate (0?78) for yearlings (SY) and the highest (0?84) for adult (ASY) females. 6. Young female tufted ducks, like adults, showed higher probabilities of moving from islands to emergent marshes when water levels were higher both before and after habitat management.

  5. Two decades of genetic profiling yields first evidence of natal philopatry and long-term fidelity to parturition sites in sharks

    Sharks are a globally threatened group of marine fishes that often breed in their natal region of origin. There has even been speculation that female sharks return to their exact birthplace to breed (\\'natal philopatry\\'), which would have important conservation implications. Genetic profiling of lemon sharks (Negaprion brevirostris) from 20 consecutive cohorts (1993-2012) at Bimini, Bahamas, showed that certain females faithfully gave birth at this site for nearly two decades. At least six females born in the 1993-1997 cohorts returned to give birth 14-17 years later, providing the first direct evidence of natal philopatry in the chondrichthyans. Long-term fidelity to specific nursery sites coupled with natal philopatry highlights the merits of emerging spatial and local conservation efforts for these threatened predators. © 2013 John Wiley & Sons Ltd.

  6. Spatial distribution of breeding Pied Flycatchers Ficedula hypoleuca in respect to their natal sites

    Sokolov, L.

    2004-06-01

    Full Text Available Study of philopatry and dispersal of pied flycatchers Ficedula hypoleuca was launched on the Courish Spit (SE Baltic in 1981. Since then, ca. 9,000 nestlings were ringed at different sites in the Russian part of the Courish Spit. A total of 557 individuals ringed as pulli were recaptured in subsequent seasons in the study area. Both males and females are more often recaptured in the plots where they were ringed than in other plots. These results were interpreted in the framework of the hypothesis forwarded by Löhrl (1959 and supported by Berndt & Winkel (1979. These authors suggested that cavity nesters (pied flycatchers and collared flycatchers F. albicollis imprint their future local breeding area during the period of postfledging exploration. Birds that survive until the next spring, return to these imprinted areas to breed. A similar study done by Sokolov et al. (1984 on the Courish Spit in an open nesting species, the chaffinch Fringilla coelebs, confirmed this finding. We assumed that juvenile pied flycatchers disperse for varying distances during their postfledging movements and imprint a local area, some 1–5 kilometres in diameter. This area is the goal of their migration next spring. It is suggested that in spring, yearlings are non–randomly distributed in respect to the area they have imprinted as juveniles. Recently, Vysotsky (2000, 2001 re–analysed the same data on philopatry of pied flycatchers on the Courish Spit and forwarded an alternative hypothesis. He suggests that juveniles, both males and females, do not imprint any local area during the postfledging period, but are distributed randomly across the area of several dozens of kilometres in spring. Vysotsky was able to show that distribution of distances of natal dispersal did not differ from the random pattern the study plot which was an 8.5 km long line of nest boxes along the Courish Spit. The aim of this study was to test these two alternative hypotheses. To do so, we

  9. Inadvertent social information in breeding site selection of natal dispersing birds

    Several species use the number of young produced as public information (PI) to assess breeding site quality. PI is inaccessible for synchronously breeding birds because nests are empty by the time the young can collect this information. We investigate if location cues are the next best source of inadvertent social information (ISI) used by young prospectors during breeding site choice. We experimentally deployed ISI as decoys and song playbacks of breeding males in suitable and sub-optimal habitats during pre- and post-breeding periods, and monitored territory establishment during the subsequent breeding season for a social, bobolink (Dolichonyx oryzivorus), and a more solitary species, Nelson's sharp-tailed sparrow (Ammodramus nelsoni). The sparrows did not respond to treatments, but bobolinks responded strongly to post-breeding location cues, irrespective of habitat quality. The following year, 17/20 sub-optimal plots to which bobolink males were recruited were defended for at least two weeks, indicating that song heard the previous year could exert a ‘carry-over attraction’ effect on conspecifics the following year. Sixteen recruited males were natal dispersers, as expected when animals have little opportunity to directly sample their natal habitat quality. We suggest that differences in breeding synchronicity may induce an equivalent clinal distribution of ISI use. PMID:16543178

    Autumn latitudinal migrations generally exhibit one of two different temporal migration patterns: type 1 where southern populations migrate south before northern populations, or type 2 where northern populations overtake southern populations en route . The ruby-throated hummingbird ( Archilochus colubris ) is a species with an expansive breeding range, which allows opportunities to examine variation in the timing of migration. Our objective was to determine a relationship between natal origin of ruby-throated hummingbirds and arrival at a Gulf coast stopover site; and if so, what factors, such as differences in body size across the range as well as the cost of migration, might drive such a pattern. To carry out our objectives, we captured hummingbirds at a coastal stopover site during autumn migration, at which time we collected feathers from juveniles for analysis of hydrogen stable isotopes. Using the hydrogen stable isotope gradient of precipitation across North America and published hydrogen isotope values of feathers from populations of breeding ruby-throated hummingbirds, we assigned migrants to probable natal latitudes. Our results confirm that individuals from across the range (30-50° N) stopover along the Gulf of Mexico and there is a positive relationship between arrival day and latitude, suggesting a type 1 migration pattern. We also found no relationship between fuel load (proxy for migration cost) or fat-free body mass (proxy for body size) and natal latitude. Our results, coupled with previous work on the spatial migration patterns of hummingbirds, show a type 1 chain migration pattern. While the mechanisms we tested do not seem to influence the evolution of migratory patterns, other factors such as resource availability may play a prominent role in the evolution of this migration system.

    Objective: This study was designed to establish risky sexual practices amongst female undergraduate students. Method: This was a descriptive cross-sectional study carried out in September 2009 amongst full-time female undergraduate students. A multi-stage sampling method was used to recruit 391 students for the study. Results: The mean age of the students was 21.4 ± 3.2 years (range 17–45 years. More than half (52.4% of the students were sexually active. The median age at first sexual intercourse was 19.0 years (range 12–24 years. Participants who had multiple sexual partners had a median of 2 (range, 2–4 sexual partners. The majority (89.3% of the students used contraceptives. Almost half (41.5%, sometimes or rarely, used contraceptives during sex. With regard to substance use, 57.5% and 6.9% respectively drank alcohol and used drugs. Sexually active students had 1.5 times (OR = 1.5, p = 0.04, (OR = Odds Ratio, more chances of consuming alcohol than those who were not sexually active. Students with multiple sexual partners were 7 times more likely to consume alcohol compared to those who did not have multiple partners (OR = 6.9, p = 0.004. Students with multiple sexual partners had 3.5 times more chances of taking drugs compared to students with one steady partner (OR = 3.5, p = 0.038. Conclusion: A large number of female university students are engaging in risky sexual practices. University Management should concentrate on developing and implementing policies to promote safer sexual practices, in particular targeting consequences of STIs and HIV and methods to minimise the risk.

    Full Text Available Participant recruitment, retention and product adherence are necessary to measure the efficacy or effectiveness of an intervention in a clinical trial. As part of a Phase III HIV prevention trial in a rural area in Kwazulu-Natal, South Africa, a peer educator programme was initiated to aid in recruitment and retention of trial participants from the community. Enrolled trial participants who had completed at least 6 months of trial participation and who had honoured all of their scheduled trial visits within that period were approached to be peer educators. Following additional selection criteria, 24 participants were eligible to be trained as peer educators. Training topics included HIV/AIDS, sexually transmitted infections, nutrition, antiretrovirals, clinical trials, and methods of disseminating this information to the community. The role of peer educators was to bring interested women from their community to the trial site for comprehensive education and information about the trial and possibly trial participation. A total of 1879 women were educated by peer educators between July 2004 and December 2006. Of these, 553 women visited the trial site for further education and screening for participation in the trial. Peer educators provided continuous education and support to women enrolled in the trial which also promoted retention, ultimately contributing to the site's 94% retention rate. Recruitment and retention efforts of trial participants are likely to be enhanced by involving trial participants as peer educators. Such trial participants are in a better position to understand cultural dynamics and hence capable of engaging the community with appropriate HIV prevention and trial-related messaging.

    At a wetland study site in Tuskegee National Forest, AL, resting female mosquitoes were collected from natural and artificial resting sites to identify species-specific resting sites and to evaluate various artificial resting sites for their utility in collecting resting mosquitoes. Natural resting sites included small tree cavities, large tree cavities, and understory vegetation. Artificial resting sites included resting boxes, fiber pots, and plastic trash cans. We collected 12,888 female mosquitoes, representing 23 species in 8 genera, during the 6-month study. Each mosquito species demonstrated a preference for a particular type of resting site. Resting Aedes vexans females were collected almost exclusively from understory vegetation, while the great majority of Anopheles quadrimaculatus females were aspirated from large tree cavities. Culex erraticus and Cx. peccator females preferred trash cans over other available resting sites. Females of Cx. territans, although collected most commonly in large tree cavities, were also collected frequently from understory vegetation and trash cans. A multiple regression of resting-site parameters (excluding vegetation), including volume, surface area, and opening size, indicated that 50% and 20% of the variability associated with An. quadrimaculatus and Cx. territans collections, respectively, could be explained by opening size. Inner surface area and volume accounted for 33% and 12% of variation in Cx. erraticus and Cx. peccator collections, respectively. Thus, female mosquitoes generally preferred larger resting sites over smaller resting sites. Similarly shaped artificial resting sites (fiber pots and trash cans) yielded comparable numbers of females per unit of volume (for those species that preferred artificial resting sites), indicating that shape of the resting site is an important factor in resting-site preference. In addition, trash cans proved to be a valuable novel tool for collecting resting female mosquitoes.

    The study aimed to explore the factors facilitating and inhibiting female condom use among female university students in South Africa. This qualitative study drew on 15 individual, in-depth interviews with female university students in Durban, South Africa. The results of the study highlight several factors that facilitate and inhibit female condom use. Protection from sexually transmitted infections (including HIV/AIDS) and prevention of pregnancy facilitated use of the device among female students. In addition, students expressed positive attitudes towards the female condom and preferred it to hormonal contraceptives because it offered them dual protection. Absence of side effects and greater power and autonomy to initiate safer sex were other factors that facilitated use. Inadequate availability, partner objection, stigma, insertion difficulties and lack of awareness served as significant barriers to consistent female condom use. Although the female condom can protect female students from infections and pregnancy, there are several barriers to its use. Interventions should aim to increase availability of the female condom, and male involvement should be increased to facilitate consistent use of the method.

    Full Text Available OBJECTIVE: The purpose of this study is to investigate the knowledge, practices, and attitudes among female university students in South Africa regarding emergency contraceptives (EC. METHODS: A cross-sectional study was conducted among 582 female university students who were selected using multi-stage sampling techniques. Multivariate logistic regression analysis was used to find significant predictors for EC awareness. RESULTS: The average age of the female students was 20.9 years (SD=3.0 and 57.2% were presently sexually active. Overall, 49.8% of the participants reported having heard about EC prior to the study. Regarding sexual activities among the female students, 53.2% reported to have sex, and 21.2% of the sexually experienced students used EC prior to the study. Regarding the effectiveness of EC, 29.5% students said it could be used up to 72 hours after unprotected sexual intercourse, and 8% said it could be used just before sex. About two-thirds (61.8% would recommend the use of EC and 63.2% would use it if they needed. The multivariate analysis indicated that students who were older (>20 years, presently sexually active, and living with their parents were more likely to be aware of EC (p<0.05. CONCLUSION: The students' knowledge and utilization of EC were low. Health education and promotion should be targeted towards these students, and the EC services should be offered on campus.

    2016-02-01

    Full Text Available Background: The South African government intervened by implementing the prevention of mother–to-child transmission programme (PMTCT to curb the HIV transmission from mother to child during and after pregnancy. The PMTCT programme has been at the forefront of global prevention efforts since 1998. Without treatment, the risk of transmission ranges from one in five to one in two newborns; however, the risk of mother-to-child transmission can be reduced to as low as 2%–5% with evidenced interventions. Sub-Saharan Africa, and most particularly South Africa, is the most affected by the pandemic despite having the largest financial investment in PMTCT services across the continent.Objectives: The objectives of the study were to describe and explore the female perspectives of male inclusion in the prevention of mother-to-child HIV transmission programme in KwaZulu-Natal.Methodology: A qualitative, descriptive, explorative study was conducted through in-depth individual interview of pregnant women until data saturation.Results: The findings of the study revealed that the existing design of public hospitals was not wholly conducive to facilitating male inclusion in maternal and child health services. Resources were largely insufficient to support the participation of pregnant mothers and any attempts to support the inclusion of males needed to be based on a clear increase in service provision.Conclusion: The study recommended male partners’ inclusion in the prevention of mother- to-child HIV transmission to support effective management of HIV in pregnancy and PMTCT programmes. The inclusion of men will provide the holistic support needed by pregnant women on PMTCT programmes.

    Activity of Swift Foxes (Vulpes velox) at den sites was studied in northwestern Texas during pup rearing seasons in 2000 and 2001 to determine role of males in parental care. Twenty-four percent of radio-collared females with a potential to breed successfully raised pups to eight weeks of age. We intensively monitored presence and absence of male and female Swift Foxes at two den sites each year. Females were present >2.6 times more at den sites than males during the pup rearing season. Female and male Swift Foxes largely stayed at dens during diurnal hours and were active away from dens during nocturnal and crepuscular hours. Females and males spent 12.4% and 3.0% more time at dens before pups emerged, than after pups emerged, respectively. Following depredation of one male parent, the female spent 29% less time at the den site. Decrease in time spent at the den by the female following loss of her mate suggested that loss of one parent might severely impact recruitment of Swift Foxes. Our observations indicated that intense Coyote (Canis latrans) depredation may severely impact pup-rearing success as well as the parental care within Swift Fox family groups.

    Sexual reference display on a social networking web site (SNS) is associated with self-reported sexual intention; females are more likely to display sexually explicit content on SNSs. The purpose of this study was to investigate male college students' views towards sexual references displayed on publicly available SNSs by females. Focus groups. One large state university. Male college students age 18-23. All tape recorded discussion was fully transcribed, then discussed to determine thematic consensus. A trained male facilitator asked participants about views on sexual references displayed on SNSs by female peers and showed examples of sexual references from female's SNS profiles to facilitate discussion. A total of 28 heterosexual male participants participated in seven focus groups. Nearly all participants reported using Facebook to evaluate potential female partners. Three themes emerged from our data. First, participants reported that displays of sexual references on social networking web sites increased sexual expectations. Second, sexual reference display decreased interest in pursuing a dating relationship. Third, SNS data was acknowledged as imperfect but valuable. Females who display sexual references on publicly available SNS profiles may be influencing potential partners' sexual expectations and dating intentions. Future research should examine females' motivations and beliefs about displaying such references and educate women about the potential impact of these sexual displays.

    1997-07-01

    Misaki feral horses were separated into 2 herds and the difference between dispersal from natal group (natal dispersal) and dispersal from natal area (natal emigration) was studied. The causes of dispersal and emigration and their effects on harem formation were studied 1979-1994. The number of horses ranged from 73 (mature males: 8, mature females: 26, young males: 8, young females: 3, colt foals: 6, filly foals: 10 and geldings: 12) in 1979 and 86 (mature males: 14, mature females: 37, young males: 12, young females: 7, colt foals: 5, filly foals: 7 and geldings: 4) in 1994 when the present study ended. All 29 males which survived to age 4 years and 58 females which survived to age 3 years left their natal or mother groups at age one to 3. Seventeen of 22 dispersing males and 29 of 39 dispersing females left their natal groups around the birth of their siblings and significant correlations were found between natal dispersal and birth of a sibling. The number of emigrating young males correlated negatively and significantly with the total number of young males in another herd and the number of emigrating young females correlated positively and significantly with the total number of young females in the natal herd. All 13 emigrating stallions which survived to age 5 years formed stable harem groups and a significant correlation was found between natal emigration and harem formation. Twenty-three of 35 resident mares formed stable consort relations with harem stallions and a significant correlation was found between residence and formation of stable consort relations.

    We studied the dispersal behavior of 1,475 northern spotted owls (Strix occidentalis caurina) during banding and radio-telemetry studies in Oregon and Washington in 1985-1996. The sample included 324 radio-marked juveniles and 1,151 banded individuals (711 juveniles, 440 non-juveniles) that were recaptured or resighted after dispersing from the initial banding location. Juveniles typically left the nest during the last week in May and the first two weeks in June (x?? ?? SE = 8 June ?? 0.53 days, n = 320, range = 15 May-1 July), and spent an average of 103.7 days in the natal territory after leaving the nest (SE = 0.986 days, n = 137, range = 76-147 days). The estimated mean date that juveniles began to disperse was 19 September in Oregon (95% CI = 17-21 September) and 30 September in Washington (95% CI = 25 September-4 October). Mean dispersal dates did not differ between males and females or among years. Siblings dispersed independently. Dispersal was typically initiated with a series of rapid movements away from the natal site during the first few days or weeks of dispersal. Thereafter, most juveniles settled into temporary home ranges in late October or November and remained there for several months. In February-April there was a second pulse of dispersal activity, with many owls moving considerable distances before settling again in their second summer. Subsequent dispersal patterns were highly variable, with some individuals settling permanently in their second summer and others occupying a series of temporary home ranges before eventually settling on territories when they were 2-5 years old. Final dispersal distances ranged from 0.6-111.2 km for banded juveniles and 1.8-103.5 km for radio-marked juveniles. The distribution of dispersal distances was strongly skewed towards shorter distances, with only 8.7% of individuals dispersing more than 50 km. Median natal dispersal distances were 14.6 km for banded males, 13.5 km for radio-marked males, 24.5 km for

  7. The Interplay Between the Public Trust Doctrine and Biodiversity and Cultural Resource Legislation in South Africa: The Case of the Shembe Church Worship Site in Tembe Elephant Park in KwaZulu-Natal

    Full Text Available Employees in the remote Tembe Elephant Park – a nature reserve in KwaZulu-Natal, South Africa – created an open-air place of worship by clearing natural vegetation. Whilst it may be argued that the damage to the protected area is insignificant, such action, for the conservation management, raises a number of principle, operational policy, and legislative questions. It is common practice for people to practice their religion within the protected area, but this usually involves the use of existing facilities and does not involve injury to the vegetation or landscape. It is argued that the unplanned establishment of a worship site is in conflict with the purpose of the establishment of the protected area and regulating legislation. It is further argued that the clearing of the site risks adding to the cumulative impact of unnatural disturbance to the protected area, which invokes consideration of the role of the Public Trust Doctrine decision and actions taken by the conservation agency on this matter. Analysis of South Africa’s conservation jurisprudence indicates a significant disparity in the provision of the Public Trust Doctrine between the biodiversity and heritage conservation legislation. The latter legislation embraces a perplexing and potentially problematic form of the Public Trust Doctrine, in that it confuses the traditional roles of the state, the trustee, and the broader public – the ‘beneficiaries’. This is a significant challenge for conservation managers drawing on the Doctrine to guide the development and implementation of an operational policy within the protected area.

  8. The Influence of Kinship on Familiar Natal Migrant Rhesus Macaques (Macaca mulatta)

    In most primate species, females remain in the natal group with kin while males disperse away from kin around the time of puberty. Philopatric females bias their social behavior toward familiar maternal and paternal kin in several species, but little is known about kin bias in the dispersing sex. Male dispersal is likely to be costly because males encounter an increased risk of predation and death, which might be reduced by dispersing together with kin and/or familiar males (individuals that were born and grew up in same natal group) or into a group containing kin and/or familiar males. Here we studied the influence of kinship on familiar natal migrant rhesus macaques (Macaca mulatta) on Cayo Santiago, Puerto Rico, by combining demographic, behavioral, and genetic data. Our data suggest that kinship influences spatial proximity between recent natal immigrants and males familiar to them. Immigrants were significantly nearer to more closely related familiar males than to more distantly related individuals. Within a familiar subgroup, natal migrants were significantly closer to maternal kin, followed by paternal kin, then non-kin, and finally to males related via both the maternal and paternal line. Spatial proximity between natal immigrants and familiar males did not decrease over time in the new group, suggesting that there is no decline in associations between these individuals within the first months of immigration. Overall, our results might indicate that kinship is important for the dispersing sex, at least during natal dispersal when kin are still available. PMID:24850977

  9. War rape, natality and genocide.

    Feminist philosophy can make an important contribution to the field of genocide studies, and issues relating to gender and war are gaining new attention. In this article I trace legal and philosophical analyses of sexual violence against women in war. I analyze the strengths and limitations of the concept of social death—introduced into this field by Claudia Card—for understanding the genocidal features of war rape, and draw on the work of Hannah Arendt to understand the central harm of genocide as an assault on natality. The threat to natality posed by the harms of rape, forced pregnancy and forced maternity lie in the potential expulsion from the public world of certain groups—including women who are victims, members of the 'enemy' group, and children born of forced birth.

    We investigated foraging decisions by adult females of the common green bottle fly, Lucilia sericata, in accordance with their physiological state. When we gave female flies a choice between visually occluded, fresh canine feces (feeding site) and a CO2-euthanized rat (carrion oviposition site), 3-d-old "protein-starved" females responded equally well to feces and carrion, whereas protein-fed gravid females with mature oocytes responded only to carrion, indicating resource preferences based on a fly's physiological state. Dimethyl trisulfide (DMTS) is known to attract gravid L. sericata females to carrion. Therefore, we analyzed headspace from canine feces by gas chromatographic-electroantennographic detection (GC-EAD) and GC/mass spectrometry. In bioassays, of the 17 fecal odorants that elicited GC-EAD responses from fly antennae, a blend of indole and one or more of the alcohols phenol, m-/p-cresol and 1-octen-3-ol proved as attractive to flies as canine feces. Unlike young females, gravid females need to locate carrion for oviposition and distinguish between fresh and aging carrion, the latter possibly detrimental to offspring. Gravid female L. sericata accomplish this task, in part, by responding to trace amounts of DMTS emanating from fresh carrion and by discriminating against carrion as soon it begins to produce appreciable amounts of indole, which is also the second-most abundant semiochemical in fresh canine feces, and apparently serves as an indicator of food rather than oviposition resources. Our results emphasize the importance of studying foraging choices by flies in accordance with their physiological stage.

    Exposure to adverse intra-uterine conditions can predispose for metabolic disorders later in life. By using a sheep model, we studied (i) how programming of glucose-insulin homoeostasis during late gestation is manifested later in life depending on the early post-natal dietary exposure and (ii) whether dietary alteration in obese individuals can prevent adverse outcomes of early life programming. During late gestation, twin-pregnant sheep were fed 100% (NORM) or 50% (LOW) of energy and protein requirements. After birth, offspring were exposed to a moderate (CONV) or high-carbohydrate-high-fat (HCHF) diet until around puberty. Offspring remaining thereafter (exclusively females) were fed a moderate diet until young adulthood. LOW lambs had increased insulin secretory responses during intravenous glucose tolerance tests indicative of reduced insulin sensitivity. HCHF lambs were hypertriglyceridaemic, 75% had mild pancreatic collagen infiltration, and their acute insulin secretory response and insulin clearance during intravenous glucose and insulin tolerance tests, respectively, were reduced. However, NORM-HCHF in contrast to LOW-HCHF lambs had normal glucose tolerance, indicating that later health outcomes are highly influenced by pre-natal nutrition. Dietary alteration normalized glucose-insulin homoeostasis in adult HCHF females, whereas late-gestation undernutrition (LOW) permanently depressed insulin sensitivity. Maintenance of glucose tolerance in sheep exposed to pre-natal undernutrition relied on pancreatic hypersecretion of insulin to compensate for reduced insulin sensitivity. A mismatching high-fat diet in early post-natal life interfered with this pancreatic hypersecretion resulting in reduced glucose tolerance. Early post-natal, but not late pre-natal, impacts on glucose-insulin homoeostasis could be reversed by dietary correction later in life. Acta Physiologica © 2013 Scandinavian Physiological Society.

    Rates of sexually transmitted infections (STIs) and unplanned pregnancy are high in Kenya, and limited reproductive health education exists in schools. We designed and implemented a 6-week reproductive health curriculum in Laikipia District, Kenya, in 2011, which included didactic sessions, educational games, and open discussions. We applied a mixed quantitative and qualitative methods to evaluate this curriculum including a comprehensive 35-item survey to assess pre- and post-training knowledge, attitudes, and practices of female teenagers regarding STIs/HIV and family planning using paired t-test as well as complementary focus groups (n=42) and individual interviews (n=20). Average age for 42 female teenagers was 16.5 (± 1.31) years. Pre-test questionnaires revealed lack of knowledge about different types of STIs, specifically chlamydia, but adequate knowledge of basic contraception including abstinence and condom use. By the conclusion of the study, we observed improvement in following educational domains: general knowledge of HIV/AIDS (85% ± 7.5% to 94% ± 5.6%) (pcurriculum was feasible, well received, and achieved its educational goals.

    Hip fracture is a kind of osteoporotic fractures in elderly patients. Its important monitoring indicator is to measure bone mineral density (BMD) using DXA. The stress characteristics and material distribution in different parts of the bones can be well simulated by three-dimensional finite element analysis. Our previous studies have demonstrated a linear positive correlation between clinical BMD and the density of three-dimensional finite element model of the femur. However, the correlation between the density variation between intertrochanteric region and collum femoris region of the model and the fracture site has not been studied yet. The present study intends to investigate whether the regional difference in the density of three-dimensional finite element model of the femur can be used to predict hip fracture site in elderly females. The CT data of both hip joints were collected from 16 cases of elderly female patients with hip fractures. Mimics 15.01 software was used to reconstruct the model of proximal femur on the healthy side. Ten kinds of material properties were assigned. In Abaqus 6.12 software, the collum femoris region and intertrochanteric region were, respectively, drawn for calculating the corresponding regional density of the model, followed by prediction of hip fracture site and final comparison with factual fracture site. The intertrochanteric region/collum femoris region density was [(1.20 ± 0.02) × 10(6)] on the fracture site and [(1.22 ± 0.03) × 10(6)] on the non-fracture site, and the difference was statistically significant (P = 0.03). Among 16 established models of proximal femur on the healthy side, 14 models were consistent with the actual fracture sites, one model was inconsistent, and one model was unpredictable, with the coincidence rate of 87.5 %. The intertrochanteric region or collum femoris region with lower BMD is more prone to hip fracture of the type on the corresponding site.

    Understanding the factors that affect dispersal is a fundamental question in ecology and conservation biology, particularly as populations are faced with increasing anthropogenic impacts. Here we collected georeferenced genetic samples (n = 2,540) from three generations of black bears (Ursus americanus) harvested in a large (47,739 km2), geographically isolated population and used parentage analysis to identify mother-offspring dyads (n = 337). We quantified the effects of sex, age, habitat type and suitability, and local harvest density at the natal and settlement sites on the probability of natal dispersal, and on dispersal distances. Dispersal was male-biased (76% of males dispersed) but a small proportion (21%) of females also dispersed, and female dispersal distances (mean ± SE  =  48.9±7.7 km) were comparable to male dispersal distances (59.0±3.2 km). Dispersal probabilities and dispersal distances were greatest for bears in areas with high habitat suitability and low harvest density. The inverse relationship between dispersal and harvest density in black bears suggests that 1) intensive harvest promotes restricted dispersal, or 2) high black bear population density decreases the propensity to disperse. Multigenerational genetic data collected over large landscape scales can be a powerful means of characterizing dispersal patterns and causal associations with demographic and landscape features in wild populations of elusive and wide-ranging species.

    Highly migratory organisms present major challenges to conservation efforts. This is especially true for exploited anadromous fish species, which exhibit long-range dispersals from natal sites, complex population structures, and extensive mixing of distinct populations during exploitation. By tracing the migratory histories of individual Chinook salmon caught in fisheries using strontium isotopes, we determined the relative production of natal habitats at fine spatial scales and different life histories. Although strontium isotopes have been widely used in provenance research, we present a new robust framework to simultaneously assess natal sources and migrations of individuals within fishery harvests through time. Our results pave the way for investigating how fine-scale habitat production and life histories of salmon respond to perturbations—providing crucial insights for conservation.

  2. A longitudinal study of Steller sea lion natality rates in the Gulf of Alaska with comparisons to census data.

    Full Text Available Steller sea lion (Eumetopias jubatus numbers in the Western Distinct Population Segment are beginning to recover following the dramatic decline that began in the 1970s and ended around the turn of the century. Low female reproductive rates (natality may have contributed to the decline and remain an issue of concern for this population. During the 2000s we found high natality among Steller sea lions in the Gulf of Alaska indicating a healthy population. This study extends these previous estimates over an additional three years and tests for interannual variations and long-term trends. We further examine the proportions of pups to adult females observed on the rookery and nearby haulouts during the birthing season to assess whether census data can be used to estimate natality. Open robust design multistate models were built and tested using Program MARK to estimate survival, resighting, and state transition probabilities in addition to other parameters dependent on whether or not a female gave birth in the previous year. Natality was estimated at 70% with some evidence of interannual variation but a long-term increasing or decreasing trend was not supported by the data. Bootstrap and regression comparisons of census data with natality estimates revealed no correlation between the two methods suggesting that census data are not an appropriate proxy for natality in this species. Longitudinal studies of individual animals are an appropriate method for estimating vital rates in species with variable detection over time such as the Steller sea lion. This work indicates that natality remains high in this region and is consistent with a population in recovery.

    The uptake and retention of a radiolabeled synthetic progestin, ORG 2058, was studied in the urinary tract of the female baboon. Four estrogen-primed baboons were injected intravenously with 2.5 micrograms./kg. body weight of 3H-ORG 2058. One animal, which served as a control, received an additional injection of 2.5 mg./kg. body weight of unlabeled progesterone. One hour after the injections, the animals were killed and the kidneys, ureters and urinary bladder were removed and processed for autoradiography. Localization of progestin was observed in the nuclei of the convoluted and straight segments of the distal tubule, the ascending thick limb of the loop of Henle and both cortical and medullary collecting tubules. Connective tissue cells were also labeled in the medulla and cortex of the kidney. An absence of silver grains was noted in the renal corpuscle, all segments of the proximal tubule and the thin loop of Henle. Concentration of the tritiated steroid was not observed in either the ureter or bladder or in any portions of the urinary tract of the control animal. This study suggests that progesterone has a direct effect via a progesterone specific receptor on the various target cells that sequestered the 3H-ORG 2058

    Full Text Available Natal teeth are those present in the oral cavity at the child’s birth. These teeth can cause ulcers on the ventral surface of the tongue, lip, and the mother’s breast characterizing the Riga-Fede Disease. The treatment depends on the tooth’s mobility and the risk of aspiration or swallowing; whether it is supernumerary or regular primary teeth; whether it is causing interference in breastfeeding; breast and oral soft tissue injuries; and the general state of child’s health. A 1-month-old female infant was diagnosed with two natal teeth and an ulcerated lesion on the ventral surface of the tongue, leading to the clinical diagnosis of Riga-Fede Disease. The treatment performed consisted of the maintenance of the natal tooth that showed no increased mobility, adding a small increment of glass ionomer cement to its incisal edge, and orientation for hygiene with saline solution. Due to the increased mobility of the other natal tooth, surgical removal was performed. There was regular monitoring of the patient and complete wound healing was observed after 15 days. The proposed treatment was successful and the patient is still in follow-up without recurrence of the lesion after one year.

    P-element transposons in the Drosophila germline mobilize only in the presence of the appropriate transposase enzyme. Sometimes, instead of mobilizing completely, P elements will undergo site-specific recombination with the homologous chromosome. Site-specific recombination is the basis for male recombination mapping, since the male germline does not normally undergo recombination. Site-specific recombination also takes place in females, but this has been difficult to study because of the obs...

    This study addresses the lack of empirical studies about the epidemic of syphilis among middle-aged female sex workers (FSWs). The objectives of this study were to investigate prevalence of syphilis, and its potential risk factors among middle-aged FSWs in China. A cross-sectional study with respondent-driven sampling (RDS). A multisite study conducted at three Chinese cites (Nanning, Hefei, and Qingdao) with different levels of sexually transmitted diseases in 2014. 1245 middle-aged female sex workers who were over 35 years old (about 400 per study site). Unprotected commercial sex, and syphilis and HIV infection were biologically tested and measured. The RDS-adjusted prevalence of active syphilis was 17.3% in Hefei, 9.9% in Qingdao, and 5.4% in Nanning. The RDS-adjusted prevalence of prevalent syphilis was between 6.8% and 33.6% in the three cities. The proportion of unprotected sex in the past 48 h verified by the prostate-specific antigen test (PSA) was between 27.8% and 42.4%. Multiple log-binomial regression analyses indicate that middle-aged FSWs who had 5 or more clients in the past week prior to interviews and engaged in unprotected sex were more likely to be active syphilitic cases. Middle-aged FSWs who had rural residency were less likely to be active syphilitic cases. In contrast with previous studies that reported low prevalence of syphilis and high prevalence of protected sex among FSWs in China, both the prevalence of syphilis and unprotected sex were high among middle-aged FSWs. Evidence-based intervention programmes should be developed and evaluated among this vulnerable population in China and other countries with similar settings.

  13. Reproductive suppression and the seasonality of reproduction in the social Natal mole-rat (Cryptomys hottentotus natalensis).

    2008-01-01

    Natal mole-rats are social subterranean rodents which exhibit a reproductive division of labour. Reproduction is confined to a single breeding female and one or more males; the remainder of the colony members is reproductively suppressed by the presence of the breeding animals. Apart from the discovery that female Natal mole-rats are induced ovulators, little is known about the reproductive biology of this species. Natal mole-rats are closely related to common and highveld mole-rats, both of which are induced ovulators and seasonal breeders. We therefore postulated that reproduction in Natal mole-rats is seasonally regulated. However, the results indicate that dominant Natal mole-rats are able to reproduce in the winter as well as in the summer. Furthermore, the increment in plasma LH in response to GnRH does not show marked seasonal differences in reproductive or non-reproductive mole-rats of either sex. Nevertheless, in all reproductive categories the level of plasma LH is significantly higher in the winter than in the summer. Seasonality in plasma LH levels dissociated from seasonality in breeding seems paradoxical. Further investigations will be required to elucidate this finding. We also investigated the processes underlying socially regulated reproduction in this species by determining basal and GnRH-evoked plasma LH in reproductive and non-reproductive animals of each sex in both seasons. The results failed to identify neuroendocrine differences consistent with an inhibited reproductive state in subordinates of either sex. Thus, the present findings suggest that behavioural interactions and/or inbreeding avoidance are the principal factors underlying suppression of reproduction in subordinate Natal mole-rats.

    This editorial comments on the latest reports of the Oxford Survey of Childhood Cancer (now based on Birmingham). With 14759 pairs, the latest survey is over 10-fold larger than the 1958 report and the calculation of fatal childhood cancer rate at one case in 990 ante-natal radiographic examinations is rather larger than the early estimates, in spite of the fetal radiation dose having been halved and the cure rate for childhood leukemia being much improved. Comments are made on the comparisons with bomb survivors, and on the much increased fatal cancer incidence after first trimester radiography. (UK)

    We evaluated site-specific skeletal adaptation to loading during growth, comparing radius (RAD) and femoral neck (FN) DXA scans in young female gymnasts (GYM) and non-gymnasts (NON). Subjects from an ongoing longitudinal study (8-26yr old) underwent annual DXA scans (proximal femur, forearm, total body) and anthropometry, completing maturity and physical activity questionnaires. This cross-sectional analysis used the most recent data meeting the following criteria: gynecological age ≤2.5yr post-menarche; and GYM annual mean gymnastic exposure ≥5.0h/wk in the prior year. Bone geometric and strength indices were derived from scans for 173 subjects (8-17yr old) via hip structural analysis (femoral narrow neck, NN) and similar radius formulae (1/3 and Ultradistal (UD)). Maturity was coded as M1 (Tanner I breast), M2 (pre-menarche, ≥Tanner II breast) or M3 (post-menarche). ANOVA and chi square compared descriptive data. Two factor ANCOVA adjusted for age, height, total body non-bone lean mass and percent body fat; significance was tested for main effects and interactions between gymnastic exposure and maturity. At the distal radius, GYM means were significantly greater than NON means for all variables (pproximal femur, GYM exhibited narrower periosteal and endosteal dimensions, but greater indices of cortical thickness, BMC, aBMD and section modulus, with lower buckling ratio (pradius BMC, width, endosteal diameter, cortical cross-sectional area, and section modulus (GYM advantages primarily post-menarche); and 3) UD radius BMC and axial compressive strength (GYM advantages were larger with greater maturity, greatest post-menarche). Maturity-specific comparisons suggested site-specific skeletal adaptation to loading during growth, with greater advantages at the radius versus the proximal femur. At the radius, GYM advantages included greater bone width, cortical cross-sectional area and cortical thickness; in contrast, at the femoral neck, GYM bone tissue cross

    Colonization of vacant habitats is an important process for supporting the long-term persistence of populations and species. We used a before–after experimental design to follow the process of colonization by steelhead Oncorhynchus mykiss (anadromous Rainbow Trout) at six monitoring sites in a natal stream, Beaver Creek, after the modification or removal of numerous stream passage barriers. Juvenile O. mykiss were collected at monitoring sites by using a backpack electrofisher. Passive integrated transponder tags and instream tag reading stations were used in combination with 16 microsatellite markers to determine the source, extent, and success of migrant O. mykiss after implementation of the barrier removal projects. Steelhead migrated into the study area during the first spawning season after passage was established. Hatchery steelhead, although comprising more than 80% of the adult returns to the Methow River basin, constituted a small proportion (23%) of the adult O. mykiss colonizing the study area. Adult steelhead and fluvial Rainbow Trout entered the stream during the first spawning season after barrier removal and were passing the uppermost tag reader (12 km upstream from the mouth) 3–4 years later. Parr that were tagged in Beaver Creek returned as adults, indicating establishment of the anadromous life history in the study area. Population genetic measures at the lower two monitoring sites (lower 4 km of Beaver Creek) significantly changed within one generation (4–5 years). Colonization and expansion of steelhead occurred more slowly than expected due to the low number of adults migrating into the study area.

    We compare binary evolution models with different assumptions about black-hole natal kicks to the first gravitational-wave observations performed by the LIGO detectors. Our comparisons attempt to reconcile merger rate, masses, spins, and spin-orbit misalignments of all current observations with state-of-the-art formation scenarios of binary black holes formed in isolation. We estimate that black holes (BHs) should receive natal kicks at birth of the order of σ ≃200 (50 ) km /s if tidal processes do (not) realign stellar spins. Our estimate is driven by two simple factors. The natal kick dispersion σ is bounded from above because large kicks disrupt too many binaries (reducing the merger rate below the observed value). Conversely, the natal kick distribution is bounded from below because modest kicks are needed to produce a range of spin-orbit misalignments. A distribution of misalignments increases our models' compatibility with LIGO's observations, if all BHs are likely to have natal spins. Unlike related work which adopts a concrete BH natal spin prescription, we explore a range of possible BH natal spin distributions. Within the context of our models, for all of the choices of σ used here and within the context of one simple fiducial parameterized spin distribution, observations favor low BH natal spin.

    Full Text Available South Africa bears the greatest burden of HIV infection globally with the most infected people living in KwaZulu-Natal (KZN. Decentralised medical care for HIV positive patients and antiretroviral therapy (ART delivery to primary health care facilities were proposed nationally to achieve adequate ART coverage for patients in need of treatment. This study described the HIV positive patients who accessed medical care and were initiated on ART at two existing government Primary Health Care (PHC clinics with no added donor support, in Ilembe, KZN. This was an observational descriptive study of ART initiation from 01 April 2008 to 30 April 2009. Data were collected from clinical records kept on site. HIV Testing and the pre-ART programmes which consisted of medical care prior to ART initiation are briefly described. Socio-economic, demographic and clinical characteristics of patients who were initiated on ART were sampled and described. A minority (2.95% of the study population tested for HIV of which 36.0%tested positive. Majority (60.0% of patients who joined the pre-ART programme care did not return. The ART sample consisted of 375 patients of whom 65.0%were women, 85.9%were unmarried, 61.6%were unemployed and 50.4%had a secondary level of education. Tuberculosis (TB prevalence and incidence at ART initiation were 22.1%and 14.7%respectively. The prevalence of Syphilis and Hepatitis B co-infections were 13.1%and 8.6 %respectively. Two thirds of female patients (66.4% received a Pap smear result of which the majority (62.3% were abnormal. Uptake for HIV testing followed by relevant CD4 testing was poor. High TB, Hepatitis B and Syphilis co-infection was noted amongst patients initiated on ART. Cervical cancer screening must be intensified. Although ART initiation with no added external resources was successful, record keeping was suboptimal.

    This cross-sectional study was aimed at determining whether certain pre-natal and natal conditions can predict specific dental anomalies. The conditions observed were: low birth-weight, preterm birth, pre-natal & natal complications. The dental anomalies observed were: enamel defects, total number of decayed, missing and filled teeth (total DMFT), disturbances in the tooth shape and disturbances in the number of teeth. Out of more than 2000 medical files of children aged 2-17 years old which were reviewed, 300 files met the selection criteria. Information recorded from the files included: age, gender, health status (the ASA physical status classification system by the American Society of Anesthesiologists), birth week, birth weight, total DMFT, hypomineralization, abnormal tooth shape, abnormal number of teeth and hypoplasia. Twenty one children out of 300 (7%) were born after a high-risk pregnancy, 25 children (8.3%) were born after high-risk birth, 20 children (6.7%) were born preterm - before week 37, and 29 children (9.7%) were born with a low birth weight (LBW) - 2500 grams or less. A relationship between a preterm birth and LBW to hypomineralization was found. And a relationship between a preterm birth and high-risk pregnancy to abnormal number of teeth was found. No relationship was found between birth (normal/high-risk) and the other parameters inspected. Preterm birth and LBW may predict hypomineralization in both primary and permanent dentitions. Furthermore, the study demonstrated that preterm birth and high-risk pregnancy may predict abnormal number of teeth in both dentitions.

    Whether to use young male or young female reference data to calculate bone mineral density (BMD) T-scores in men remains controversial. The third National Health and Nutrition Examination and Survey (NHANES III) data show that the mean and standard deviation of femoral neck and total hip BMD is greater in young men than young women, and therefore differences in T-scores at these sites using NHANES III female vs male norms becomes less as BMD decreases. In contrast, manufacturer-specific reference databases generally assume similar standard deviations of BMD in men and women. Using NHANES III reference data for the femoral neck and total hip, respectively we found that men with T-scores of -2.5 when young male norms are used have T-scores of -2.4 and -2.3 when young female norms are used. Using manufacturer-specific reference data, we found that men with T-scores of -2.5 when young male norms are used at the femoral neck, total hip, lumbar spine, or one-third of the forearm would have T-scores ranging from -2.4 to -0.4 when young female norms are used, depending on skeletal site and densitometer manufacturer. The change of proportions of men diagnosed with osteoporosis when young female norms are used instead of young male reference data differs substantially according to skeletal site and densitometer manufacturer.

  7. Are female monarch butterflies declining in eastern North America? Evidence of a 30-year change in sex ratios at Mexican overwintering sites

    Science.gov (United States)

    Davis, Andrew K.; Rendón-Salinas, Eduardo

    2010-01-01

    Every autumn the entire eastern North American population of monarch butterflies (Danaus plexippus) undergoes a spectacular migration to overwintering sites in the mountains of central Mexico, where they form massive clusters and can number in the millions. Since their discovery, these sites have been extensively studied, and in many of these studies, monarchs were captured and sexes recorded. In a recent effort to compile the sex ratio data from these published records, a surprising trend was found, which appears to show a gradual decline in proportion of females over time. Sex ratio data from 14 collections of monarchs, all spanning 30 years and totaling 69 113 individuals, showed a significant negative correlation between proportion of females and year (r = −0.69, p = 0.007). Between 1976 and 1985, 53 per cent of overwintering monarchs were female, whereas in the last decade, 43 per cent were female. The relationship was significant with and without weighting the analyses by sampling effort. Moreover, analysis of a recent three-year dataset of sex ratios revealed no variation among nine separate colonies, so differences in sampling location did not influence the trend. Additional evidence from autumn migration collections appears to confirm that proportions of females are declining, and also suggests the sex ratio is shifting on breeding grounds. While breeding monarchs face a number of threats, one possibility is an increase in prevalence of the protozoan parasite, Ophryocystis elektroscirrha, which recent evidence shows affects females more so than males. Further study will be needed to determine the exact cause of this trend, but for now it should be monitored closely. PMID:19776062

  10. Experiences of childbirth in Natal Indian women

    H.B. Brookes

    1991-09-01

    Full Text Available Through fifteen in-depth case studies of primipara, Natal Indian women’s experiences of childbirth have been described Common problems were identified, including lack of a family support person throughout labour, lithotomy position for delivery, episiotomies and their sequelae, breast-feeding difficulties and lack of professional support in the early puerperium at home. Preparation for common medical interventions in labour, breast-feeding and parenting appeared inadequate. Pertinent sociocultural aspects have been identified. These include continuing family support and culturally prescribed behaviour pertaining most importantly to the early puerperium and affecting the maternal-neonatal dyad. In the early adaptation to motherhood informants continued their role as daughter or daughter-in-law and would only actively continue their role as wife later or at the end of the puerperium. These traditional patterns of behaviour persist despite marked changes in educational level, language spoken and employment status. In the light of this research and founded on scientific evidence, a number of recommendations are made and areas for further research are identified

    A project is described in which the Epidemiologic Studies Branch, DBE, is cooperating with the National Center for Health Statistics in a National Natality Survey and a National Fetal Mortality Survey of a sample of live births and of late fetal deaths (28 or more weeks gestation) in 1979. Questionnaires will be sent to a sample of mothers who had a live born infant or late fetal death in 1979, to hospitals in which the deliveries took place, to attending physicians, and all other possible sources of health care. The survey will provide quantitative information regarding use of ionizing and nonionizing radiation, including ultrasound, during pregnancy and possible associations between radiation and late fetal mortality. Specifically the study will provide information on the demographic and socioeconomic characteristics of the mothers and complications of pregnancy, labor, and delivery. The physical condition of the infant at birth is also included. This is one of many health surveys conducted routinely by the NCHS under the National Health Survey program

    It is commonly assumed that the propensity to disperse and the dispersal distance of mammals should increase with increasing density and be greater among males than among females. However, most empirical evidence, especially on large mammals, has focused on highly polygynous and dimorphic species displaying female-defence mating tactics. We tested these predictions on roe deer, a weakly polygynous species of large herbivore exhibiting a resource-defence mating tactic at a fine spatial scale. Using three long-term studies of populations that were subject to the experimental manipulation of size, we did not find any support for either prediction, whether in terms of dispersal probability or dispersal distance. Our findings of similar dispersal patterns in both sexes of roe deer suggest that the underlying cause of natal dispersal is not related to inbreeding avoidance in this species. The absence of positive density dependence in fine-scale dispersal behaviour suggests that roe deer natal dispersal is a pre-saturation process that is shaped by heterogeneities in habitat quality rather than by density per se.

  13. [Recent evolution of natality and fertility in Venezuela].

    Science.gov (United States)

    Picouet, M R

    1977-01-01

    Venezuela, like the majority of Latin American countries, has experienced an important decrease in fertility rate since 1960; it was 48/1000 in 1954, the highest level ever, but only 36.6/1000 in 1975. This phenomenon implies the intervention of new factors which affected birth rate. Birth underegistration in Venezuela has always been a problem; it has decreased from 8% in 1950, to 6% in 1971, but it is still necessary to make corrections in the observed birth rate to have a figure nearer to reality. Thus, while observed birth rate was 45.9/1000 in 1960, and 36.6 in 1975, the estimated birth rate was 47.7 and 38.1 in the same years. The computation of age-specific fertility rate shows an increase up to 1960, a stabilization between 1960 and 1967, and a progressive decrease after 1968. An interpretation of the recent evolution in birth and fertility rate must take into consideration the number of women exposed to the risk of pregnancy, the changes in rate of marriage, and especially the changes in reproductive behavior. Family planning programs have been available in Venezuela since 1963, and there are now about 150 clinics which provide contraceptive information and services. However, the female population covered by such programs is only 12%; this means that numerous women seek contraception outside of organized programs, and that, indeed, birth control precedes years of the diffusion of contraceptive methods. With an estimated birth rate of 38.1/1000 in 1975, Venezuela still has one of the highest natality rates in the world.

  14. Polyalanine repeat polymorphism in RUNX2 is associated with site-specific fracture in post-menopausal females.

    Directory of Open Access Journals (Sweden)

    Nigel A Morrison

    Full Text Available Runt related transcription factor 2 (RUNX2 is a key regulator of osteoblast differentiation. Several variations within the RUNX2 gene have been found to be associated with significant changes in BMD, which is a major risk factor for fracture. In this study we report that an 18 bp deletion within the polyalanine tract (17A>11A of RUNX2 is significantly associated with fracture. Carriers of the 11A allele were found to be nearly twice as likely to have sustained fracture. Within the fracture category, there was a significant tendency of 11A carriers to present with fractures of distal radius and bones of intramembranous origin compared to bones of endochondral origin (p = 0.0001. In a population of random subjects, the 11A allele was associated with decreased levels of serum collagen cross links (CTx, p = 0.01, suggesting decreased bone turnover. The transactivation function of the 11A allele showed a minor quantitative decrease. Interestingly, we found no effect of the 11A allele on BMD at multiple skeletal sites. These findings suggest that the 11A allele is a biologically relevant polymorphism that influences serum CTx and confers enhanced fracture risk in a site-selective manner related to intramembranous bone ossification.

  15. Scaling of Natal Dispersal Distances in Terrestrial Birds and Mammals

    Directory of Open Access Journals (Sweden)

    Glenn D. Sutherland

    2000-07-01

    Full Text Available Natal dispersal is a process that is critical in the spatial dynamics of populations, including population spread, recolonization, and gene flow. It is a central focus of conservation issues for many vertebrate species. Using data for 77 bird and 68 mammal species, we tested whether median and maximum natal dispersal distances were correlated with body mass, diet type, social system, taxonomic family, and migratory status. Body mass and diet type were found to predict both median and maximum natal dispersal distances in mammals: large species dispersed farther than small ones, and carnivorous species dispersed farther than herbivores and omnivores. Similar relationships occurred for carnivorous bird species, but not for herbivorous or omnivorous ones. Natal dispersal distances in birds or mammals were not significantly related to broad categories of social systems. Only in birds were factors such as taxonomic relatedness and migratory status correlated with natal dispersal, and then only for maximum distances. Summary properties of dispersal processes appeared to be derived from interactions among behavioral and morphological characteristics of species and from their linkages to the dynamics of resource availability in landscapes. In all the species we examined, most dispersers moved relatively short distances, and long-distance dispersal was uncommon. On the basis of these findings, we fit an empirical model based on the negative exponential distribution for calculating minimum probabilities that animals disperse particular distances from their natal areas. This model, coupled with knowledge of a species' body mass and diet type, can be used to conservatively predict dispersal distances for different species and examine possible consequences of large-scale habitat alterations on connectedness between populations. Taken together, our results can provide managers with the means to identify species vulnerable to landscape-level habitat changes

    Full Text Available We studied natality in the Northern Alaska Peninsula (NAP and Southern Alaska Peninsula (SAP caribou (Rangifer tarandus granti herds during 1996-1999, and mortality and weights of calves during 1998 and 1999- Natality was lower in the NAP than the SAP primarily because most 3-year-old females did not produce calves in the NAP Patterns of calf mortality in the NAP and SAP differed from those in Interior Alaska primarily because neonatal (i.e., during the first 2 weeks of life mortality was relatively low, but mortality continued to be significant through August in both herds, and aggregate annual mortality was extreme (86% in the NAP Predators probably killed more neonatal calves in the SAP, primarily because a wolf den (Canis lupus was located on the calving area. Despite the relatively high density of brown bears (Ursus arctos and bald eagles (Haliaeetus leucocephalus, these predators killed surprisingly few calves. Golden eagles (Aquila chrysaetos were uncommon on the Alaska Peninsula. At least 2 calves apparently died from pneu¬monia in the range of the NAP but none were suspected to have died from disease in the range of the SAP. Heavy scav¬enging by bald eagles complicated determining cause of death of calves in both the NAP and SAP.

  8. FUNCTIONALLY UNIVENTRICULAR HEARTS: IMPACT OF PRE-NATAL DIAGNOSIS

    Full Text Available Within the last few decades the pre-natal echocardiographic diagnosis of congenital heart defects has made substantial progresses, particularly for the identification of complex malformation. Functionally univentricular hearts categorize a huge variety of heart malformations. Since no one of the patients with these congenital heart defects can ever undergo a bi-ventricular type of repair, early recognition and decision-making from the neonatal period are required in order to allow for appropriate multiple-step diagnostic and treatment procedures, either of interventional cardiology and/or surgery, on the pathway of univentricular heart. In the literature strong disagreements exist about the potential impact of the pre-natal diagnosis on the early and late outcomes of complex congenital heart defects. This review of the recent reports has been undertaken to better understand the impact of pre-natal diagnosis in functionally univentricular hearts taking into consideration the following topics:•pre-natal screening•outcomes and survival•general morbidity•neurologic and developmental consequences•pregnancy management and delivery planning•resources utilization and costs/benefits issues•ethical implications, parents counseling, interruption of pregnancy versus treatment

  5. Consequences of pre-natal radiation exposure for post-natal development

    Mole, R.H.

    1982-01-01

    A review of revised observations on Japanese bomb survivors suggests that 10-18 weeks of pregnancy is the period of greatest sensitivity for foetal brain damage leading to severe mental retardation. Severe food deficiencies suggest a cause for the apparently high frequency of severe mental retardation in the unexposed control population and may also have contributed to the dose-dependent increase in those irradiated in utero. The author concludes that there is no confirmed evidence to suggest that the pre-implantation stage of mammalian development is unusually radiosensitive. In the human, the succeeding period of major organogenesis seems to be less sensitive and important than the following 10-18 week period of pregnancy. It is suggested that malformation (teratogenesis) should be distinguished from maldevelopment. Malformations are the result of failure of embryonic organization and ionizing radiation is not an efficient teratogen in this sense. Maldevelopment after exposure to radiation is the consequence of cell depletion of sufficient degree randomly distributed throughout an irradiated tissue. It is concluded that dose thresholds for maldevelopments are to be expected after irradiation both in pre-implantation and post-implantation stages, and that somatic mutation has a possible role as a mechanism without threshold for development damage by pre-natal irradiation, but not likely to be of practical significance.

  6. The Relationship between Social Networking Site Use and the Internalization of a Thin Ideal in Females: A Meta-Analytic Review

    Full Text Available Previous research has indicated that exposure to traditional media (i.e., television, film, and print predicts the likelihood of internalization of a thin ideal; however, the relationship between exposure to internet-based social media on internalization of this ideal remains less understood. Social media differ from traditional forms of media by allowing users to create and upload their own content that is then subject to feedback from other users. This meta-analysis examined the association linking the use of social networking sites (SNSs and the internalization of a thin ideal in females. Systematic searches were performed in the databases: PsychINFO, PubMed, Web of Science, Communication and Mass Media Complete, and ProQuest Dissertations and Theses Global. Six studies were included in the meta-analysis that yielded 10 independent effect sizes and a total of 1,829 female participants ranging in age from 10 to 46 years. We found a positive association between extent of use of SNSs and extent of internalization of a thin ideal with a small to moderate effect size (r = 0.18. The positive effect indicated that more use of SNSs was associated with significantly higher internalization of a thin ideal. A comparison was also made between study outcomes measuring broad use of SNSs and outcomes measuring SNS use solely as a function of specific appearance-related features (e.g., posting or viewing photographs. The use of appearance-related features had a stronger relationship with the internalization of a thin ideal than broad use of SNSs. The finding suggests that the ability to interact with appearance-related features online and be an active participant in media creation is associated with body image disturbance. Future research should aim to explore the way SNS users interact with the media posted online and the relationship linking the use of specific appearance features and body image disturbance.

    Atlantic bluefin tuna populations are in steep decline, and an improved understanding of connectivity between individuals from eastern (Mediterranean Sea) and western (Gulf of Mexico) spawning areas is needed to manage remaining fisheries. Chemical signatures in the otoliths of yearlings from regional nurseries were distinct and served as natural tags to assess natal homing and mixing. Adults showed high rates of natal homing to both eastern and western spawning areas. Trans-Atlantic movement (east to west) was significant and size-dependent, with individuals of Mediterranean origin mixing with the western population in the U.S. Atlantic. The largest (oldest) bluefin tuna collected near the northern extent of their range in North American waters were almost exclusively of western origin, indicating that this region represents critical habitat for the western population.

  11. Evolution of natal dispersal in spatially heterogenous environments.

    2017-01-01

    Understanding the evolution of dispersal is an important issue in evolutionary ecology. For continuous time models in which individuals disperse throughout their lifetime, it has been shown that a balanced dispersal strategy, which results in an ideal free distribution, is evolutionary stable in spatially varying but temporally constant environments. Many species, however, primarily disperse prior to reproduction (natal dispersal) and less commonly between reproductive events (breeding dispersal). These species include territorial species such as birds and reef fish, and sessile species such as plants, and mollusks. As demographic and dispersal terms combine in a multiplicative way for models of natal dispersal, rather than the additive way for the previously studied models, we develop new mathematical methods to study the evolution of natal dispersal for continuous-time and discrete-time models. A fundamental ecological dichotomy is identified for the non-trivial equilibrium of these models: (i) the per-capita growth rates for individuals in all patches are equal to zero, or (ii) individuals in some patches experience negative per-capita growth rates, while individuals in other patches experience positive per-capita growth rates. The first possibility corresponds to an ideal-free distribution, while the second possibility corresponds to a "source-sink" spatial structure. We prove that populations with a dispersal strategy leading to an ideal-free distribution displace populations with dispersal strategy leading to a source-sink spatial structure. When there are patches which cannot sustain a population, ideal-free strategies can be achieved by sedentary populations, and we show that these populations can displace populations with any irreducible dispersal strategy. Collectively, these results support that evolution selects for natal or breeding dispersal strategies which lead to ideal-free distributions in spatially heterogenous, but temporally homogenous

    Developmental dysplasia of the hip (DDH) is a developmental defect that prevents normal articulation between the acetabulum and the femoral head. This is an unusual condition, with a prevalence of 1-2 per thousand, and with only two poorly described skeletons documented in South American paleopathological literature. In this work we report an individual with such a condition, from the archeological site Tres Cruces I (Quebrada del Toro, Salta, Argentina). Several radiocarbon dates and associated materials date it to the Superior Formative (400-1000 AD). The remains are of an adult female, who also has tabular oblique cranial modification. Through detection of abnormalities in the morphology of the femora and ossa coxae, a differential diagnosis was carried out. On the left hip joint the formation of a well-defined false acetabulum, without connection with the true one, was observed. The latter was shallow, triangular, with an irregular base. The left os coxae showed a wider greater sciatic notch angle. The right os coxae exhibited a false acetabulum connected with the true one. Both femora presented a small femoral head, flat and mushroom-shaped, with shortening of the neck. These features were more pronounced on the right-side elements. On the basis of the aforementioned, a presumptive diagnosis of bilateral developmental dysplasia of the hip with complete dislocation on both sides was established. Copyright © 2017 Elsevier Inc.

    The epidemic of HIV/AIDS continues to spread among older adults and mid-age female sex workers (FSWs) over 35 years old. We used egocentric network data collected from three study sites in China to examine the applicability of Burt's Theory of Social Holes to study social support among mid-age FSWs. Using respondent-driven sampling, 1245 eligible mid-age FSWs were interviewed. Network structural holes were measured by network constraint and effective size. Three types of social networks were identified: family networks, workplace networks, and non-FSW networks. A larger effective size was significantly associated with a higher level of social support [regression coefficient (β) 5.43-10.59] across the three study samples. In contrast, a greater constraint was significantly associated with a lower level of social support (β -9.33 to -66.76). This study documents the applicability of the Theory of Structural Holes in studying network support among marginalized populations, such as FSWs.

    Information regarding polychlorinated biphenyls (PCBs) in environmental media in Africa is limited. This paper presents results of a monitoring program conducted in KwaZulu-Natal Province, South Africa designed to characterize levels, trends and sources of airborne PCBs. Particulate and vapor samples were sampled over the 2004-2005 period at three sites. The total PCB concentration averaged 128 {+-} 47 pg m{sup -3}, and levels were highest in winter. Tri- through hexa-congeners predominated, and the vapor fraction was predominant. Several tetra- through hexa-chlorinated congeners had levels comparable to those at urban sites in the northern hemisphere, but hepta- through deca-congeners resembled levels at background sites. PCB source areas, deduced using spatial and temporal patterns, compositional information and trajectory analyses, likely included local, regional and global sources. Soils at three rural sites showed high PCB concentrations, and milk from a local dairy showed PCB concentrations comparable to USA levels in year 2000. - Airborne PCBs in KwaZulu-Natal, South Africa have similar concentrations but distinctive congener patterns compared to areas of historically high PCB use.

    Full Text Available Abstract Background Lepidium meyenii, known as Maca, grows exclusively in the Peruvian Andes over 4000 m altitude. It has been used traditionally to increase fertility. Previous scientific studies have demonstrated that Maca increases spermatogenesis and epididymal sperm count. The present study was aimed to investigate the effects of Maca on several fertility parameters of female mice at reproductive age. Methods Adult female Balb/C mice were divided at random into three main groups: i Reproductive indexes group, ii Implantation sites group and iii Assessment of uterine weight in ovariectomized mice. Animals received an aqueous extract of lyophilized Yellow Maca (1 g/Kg BW or vehicle orally as treatment. In the fertility indexes study, animals received the treatment before, during and after gestation. The fertility index, gestation index, post-natal viability index, weaning viability index and sex ratio were calculated. Sexual maturation was evaluated in the female pups by the vaginal opening (VO day. In the implantation study, females were checked for implantation sites at gestation day 7 and the embryos were counted. In ovariectomized mice, the uterine weight was recorded at the end of treatment. Results Implantation sites were similar in mice treated with Maca and in controls. All reproductive indexes were similar in both groups of treatment. The number of pups per dam at birth and at postnatal day 4 was significantly higher in the group treated with Maca. VO day occurred earlier as litter size was smaller. Maca did not affect VO day. In ovariectomized mice, the treatment with Maca increased significantly the uterine weights in comparison to their respective control group. Conclusion Administration of aqueous extract of Yellow Maca to adult female mice increases the litter size. Moreover, this treatment increases the uterine weight in ovariectomized animals.

  19. Lack of pubertal influences on female dispersal in muriqui monkeys, Brachyteles arachnoides.

    Strier; Ziegler

    2000-04-01

    The hormonal mediation of dispersal in female mammals is poorly understood, in part because of the difficulties of detecting the onset of ovarian cycling and puberty in dispersing individuals. We used noninvasive methods of faecal steroid assays to determine the timing of dispersal relative to puberty and ovarian cycling in wild female muriqui monkeys, a species in which males are philopatric and nearly all females transfer from their natal groups. Natal females had a mean+/-SE age of 73.4+/-7.2 months (N=18) at the time of their transfers. Intergroup transfers occurred when one or more sexually active adult females were present, but did not show any seasonal patterns. Faecal progesterone and oestradiol profiles from nine natal females prior to transfer and four non-natal females that transferred into our study group demonstrate unequivocally that dispersal occurs prior to puberty in this species. All females showed baseline oestradiol levels and low progesterone levels compared with cycling adult females. Immigrants were first observed to copulate at 11.2+/-2.2 months of age (N=4), prior to the onset of normal ovarian cycles, and gave birth to their first offspring at 33.8+/-7.3 months (N=4) after transferring. Mean cortisol levels did not differ between natal emigrants or recent immigrants, and were within the range of those of adult males during the nonbreeding season in 10 of the 11 prepubertal females sampled. These results indicate that female dispersal is not triggered by activational hormones associated with puberty or escape from reproductive suppression in this species.

    Full Text Available South Africa bears the greatest burden of HIV infection globally with the most infected people living in KwaZulu-Natal (KZN. Decentralised medical care for HIV positive patients and antiretroviral therapy (ART delivery to primary health care facilities were proposed nationally to achieve adequate ART coverage for patients in need of treatment. This study described the HIV positive patients who accessed medical care and were initiated on ART at two existing government Primary Health Care (PHC clinics with no added donor support, in Ilembe, KZN. This was an observational descriptive study of ART initiation from 01 April 2008 to 30 April 2009. Data were collected from clinical records kept on site. HIV Testing and the pre-ART programmes which consisted of medical care prior to ART initiation are briefly described. Socio-economic, demographic and clinical characteristics of patients who were initiated on ART were sampled and described. A minority (2.95% of the study population tested for HIV of which 36.0% tested positive. Majority (60.0% of patients who joined the pre-ART programme care did not return. The ART sample consisted of 375 patients of whom 65.0% were women, 85.9% were unmarried, 61.6% were unemployed and 50.4% had a secondary level of education. Tuberculosis (TB prevalence and incidence at ART initiation were 22.1% and 14.7% respectively. The prevalence of Syphilis and Hepatitis B co-infections were 13.1% and 8.6 % respectively. Two thirds of female patients (66.4% received a Pap smear result of which the majority (62.3% were abnormal. Uptake for HIV testing followed by relevant CD4 testing was poor. High TB, Hepatitis B and Syphilis co-infection was noted amongst patients initiated on ART. Cervical cancer screening must be intensified. Although ART initiation with no added external resources was successful, record keeping was suboptimal.

  1. Age at first reproduction in philopatric female muriquis ( Brachyteles arachnoides hypoxanthus).

    Female northern muriquis ( Brachyteles arachnoides hypoxanthus or B. hypoxanthus) at the Estação Biológica de Caratinga/RPPN-FMA, Minas Gerais, Brazil typically disperse from their natal groups at an average age of 6.1+/-0.6 years (median =6.0 years, range =5.3-7.8 years, n =22), prior to the onset of puberty and sexual activity. Immigrants do not conceive until at least their second mating season, and the minimum interval from immigration to first reproduction has been 2.0 years. Age at first reproduction in dispersing females, previously estimated at 8.9 years, has now been documented at 9.0 and 9.25 years for two females whose birth dates are known. This is older than the 7.5 years at which the only female previously known to have reproduced in her natal group gave birth. Here, we present new data from a second female that reproduced in her natal group. This female (BA) was first observed to copulate at 5.5 years, and gave birth to her first infant at 7.25 years of age. Her 1.75-year cycling-to-first conception delay was only slightly shorter than the minimum recorded for immigrant females, and thus was not responsible for her young age at first reproduction compared to dispersing females. Although our sample size is small, our findings suggest that early puberty may permit females to reproduce in their natal group, implying a possible link between life history trade-offs and dispersal patterns. Because the only two females that have reproduced in their natal group were maternal sisters, it is also possible that maternal effects on age at puberty can impact dispersal patterns, particularly in small populations of primates.

    Full Text Available Many studies have shown that juvenile salmon imprint olfactory memory of natal stream odors during downstream migration, and adults recall this stream-specific odor information to discriminate their natal stream during upstream migration for spawning. The odor information processing of the natal stream in the salmon brain, however, has not been clarified. We applied blood oxygenation level-dependent (BOLD functional magnetic resonance imaging to investigate the odor information processing of the natal stream in the olfactory bulb and telencephalon of lacustrine sockeye salmon (Oncorhynchus nerka. The strong responses to the natal stream water were mainly observed in the lateral area of dorsal telencephalon (Dl, which are homologous to the medial pallium (hippocampus in terrestrial vertebrates. Although the concentration of L-serine (1 mM in the control water was 20,000-times higher than that of total amino acid in the natal stream water (47.5 nM, the BOLD signals resulting from the natal stream water were stronger than those by L-serine in the Dl. We concluded that sockeye salmon could process the odor information of the natal stream by integrating information in the Dl area of the telencephalon.

    Full Text Available We explored the recent cementation of modern beachrock on the seaward margin of the Durban Bluff, central KwaZulu-Natal. The low latitude and subtropical climatic setting is a unique context compared to the more commonly documented contemporary beachrock formation in the tropics. Geological field mapping was carried out and here we present results based on sedimentary facies of a clastic shoreline and carbonate diagenesis of interstitial cements using transmitted light microscopy. The beachrock was cemented by micrite and aragonite, and iron oxide infilled voids. The presence of human artefacts within the deposit showed evidence for cementation within the last century. The elevation (at Mean Low Water and correlation to rates of sea level change for the east coast of South Africa showed that the beachrock is less than 72 years in age. In contrast to older local Pleistocene deposits, beachrocks have cemented along this stretch of coast during successive sea level highstands with similar climatic regimes – the last Interglacial, the Holocene High and the present. Here we report the most southerly documentation of modern beachrock in KwaZulu-Natal, which, to our knowledge, represents the youngest deposit reported in southern Africa.

  12. Individual patterns of habitat and nest-site use by hosts promote transgenerational transmission of avian brood parasitism status.

    Science.gov (United States)

    Hoover, Jeffrey P; Hauber, Mark E

    2007-11-01

    Brood parasitic birds impose variable fitness costs upon their hosts by causing the partial or complete loss of the hosts' own brood. Growing evidence from multiple avian host-parasite taxa indicates that exposure of individual hosts to parasitism is not necessarily random and varies with habitat use, nest-site selection, age or other phenotypic attributes. For instance, nonrandom patterns of brood parasitism had similar evolutionary consequences to those of limited horizontal transmission of parasites and pathogens across space and time and altered the dynamics of both population productivity and co-evolutionary interactions of hosts and parasites. We report that brood parasitism status of hosts of brown-headed cowbirds Molothrus ater is also transmitted across generations in individually colour-banded female prothonotary warblers Protonotaria citrea. Warbler daughters were more likely to share their mothers' parasitism status when showing natal philopatry at the scale of habitat patch. Females never bred in their natal nestboxes but daughters of parasitized mothers had shorter natal dispersal distances than daughters of nonparasitized mothers. Daughters of parasitized mothers were more likely to use nestboxes that had been parasitized by cowbirds in both the previous and current years. Although difficult to document in avian systems, different propensities of vertical transmission of parasitism status within host lineages will have critical implications both for the evolution of parasite tolerance in hosts and, if found to be mediated by lineages of parasites themselves, for the difference in virulence between such extremes as the nestmate-tolerant and nestmate-eliminator strategies of different avian brood parasite species.

    The current study constituted part of a larger, longitudinal, South African-based study, namely, The Road and Aircraft Noise Exposure on Children's Cognition and Health (RANCH-South Africa). In the context of a multicultural South Africa and varying demographic variables thereof, this study sought to investigate and describe the effects of gender, socioeconomic status and home language on primary school children's reading comprehension in KwaZulu-Natal. In total, 834 learners across 5 public schools in the KwaZulu-Natal province participated in the study. A biographical questionnaire was used to obtain biographical data relevant to this study, and the Suffolk Reading Scale 2 (SRS2) was used to obtain reading comprehension scores. The findings revealed that there was no statistical difference between males and females on reading comprehension scores. In terms of socioeconomic status (SES), learners from a low socioeconomic background performed significantly better than those from a high socioeconomic background. English as a First Language (EL1) speakers had a higher mean reading comprehension score than speakers who spoke English as an Additional Language (EAL). Reading comprehension is indeed affected by a variety of variables, most notably that of language proficiency. The tool to measure reading comprehension needs to be standardized and administered in more than one language, which will ensure increased reliability and validity of reading comprehension scores.

    2011-01-01

    This article examines the contradictions that African girls' schooling presented for colonial governance in Natal, through the case study of Inanda Seminary, the region's first and largest all-female school for Africans. While patriarchal colonial law circumscribed the educational options of girls whose fathers opposed their schooling, the head of Natal's nascent educational bureaucracy argued that African girls' education in Western domesticity would be essential in creating different sorts of families with different sorts of needs. In monogamous families, Native Schools Inspector Robert Plant argued, husbands and sons would be taught to 'want' enough to impel them to labour for wages - but they would also be sufficiently satisfied by their domestic comforts to avoid political unrest. Thus, even as colonial educational officials clamped down on African boys' curricula - attempting to restrict their schooling to the barest preparation for unskilled wage labour - they allowed missionaries autonomy to educate young women whose fathers did not challenge their school attendance. This was because young women's role in the social reproduction of new sorts of families made their education ultimately appear to be a benefit to colonial governance. As young men pursued wage labour, young women began to comprise the majority of African students, laying the groundwork for the feminisation of schooling in modern southern Africa.

    Men's sexual arousal patterns are category-specific: Men typically display significantly greater physiological responses to sexual stimuli depicting members of their preferred gender category. Category-specific patterns of sexual arousal have not been consistently reported in natal women. We used vaginal photoplethysmography to examine patterns of sexual arousal in 11 male-to-female (MtF) transsexuals following sex reassignment surgery (SRS) and in 72 natal women. Subjective arousal was measured with a continuous response lever. Video clips depicting sexual activity between two males, two females, or one male and one female were used as erotic stimuli. All transsexual participants displayed category-specific sexual arousal. Five homosexual transsexual participants (attracted exclusively to males before sex reassignment) showed greater genital and subjective responses to male than to female stimuli, while six nonhomosexual transsexual participants showed the opposite pattern. Vaginal pulse amplitude (VPA) was lower in transsexual participants than in natal women. The mean correlation between VPA and subjective responses was high in nonhomosexual transsexuals, but was significantly lower in homosexual transsexuals and in natal women. One transsexual participant who reported a change in sexual orientation following sex reassignment displayed VPA and subjective responses consistent with her pre-reassignment sexual orientation. We conclude that male-to-female transsexuals display male-typical category-specific sexual arousal following SRS, and that vaginal photoplethysmography is a promising methodology for studying patterns of sexual arousal in postoperative transsexuals.

    Post-natal stress has been shown to have important short and long term effects on many adult traits in birds. During stress, metabolic alterations often result in the mobilization of energy away from energy-sensitive functions such as growth, which could have significant implications for developing animals. However, little is known about the implications of stress hormones for energy consumption in growing individuals. We experimentally increased corticosterone (CORT) levels in nestling zebra finches via oral administration, between the ages of 7 and 18 days. The standard metabolic rate (SMR) of birds was measured twice overnight when birds were between 11-13 and 55-65 days of age. Developmental CORT administration significantly elevated overnight variability in SMR (sd) in nestling birds (during the treatment period), but not at 55-65 days (5-6 weeks after the treatment period). The effect on variability was seen more prominently in birds from larger brood sizes and in females. We found no effects of our treatments on mean SMR overnight. However, brood size and sex had interactive effects, with males from larger brood sizes having higher SMR at 55-65 days of age. These results suggest that stress hormones can have significant effects on energy metabolism and possibly nocturnal arousal and sleep fragmentation. However, there were no detectable long term effects of our treatments on SMR, suggesting that these effects are only short-lived, in order to maintain homeostasis in the short term.

    Various interventions have resulted in increased rates of HIV testing. However, encouraging men to acknowledge their risk for HIV, to test and link to treatment remains a challenge. In this study, we examine men's perspectives on navigating HIV risk in rural KwaZulu-Natal, South Africa. Qualitative interviews were conducted at four intervals over a three-year time period with a baseline cohort of 126 men and women. We found that men navigated HIV risk in their sexual relationships mainly by monitoring their partner's behaviour. Men expressed concerns about female respectability, invoking discourses on hlonipha rooted in Zulu cultural ideals and Christian ideals about women staying close to home. In the post-apartheid era, these concerns were inflected by anxieties over changing gender norms and the high rates and risks of infection in the region. HIV prevention discourses on behaviour intersected with men's efforts to assert their masculinity through the monitoring and controlling of women's behaviour. The potential negative impacts of this should be addressed. Prevention efforts need to focus on men's vulnerability to infection in terms of their own behaviour as well as the contexts in which they live.

Although, 95% of the Sri Lankan mutated genetic sites for thalassaemia are known, more research will be needed to identify the other rare sites. The publication of this paper, with its novelty for pre-natal diagnosis, would encourage clinicians to practice it in other centres and to extend it to families with other genetic disorders.

    The growing gray seal population in the Baltic Sea has led to increased conflicts with fisheries. Despite limited data on gray seal ecology, management measures, such as culling, have been implemented recently. We studied movements and site fidelity of Baltic gray seals using mark-recapture analysis based on photographic identification of individuals (photo-id). Seals were photographed at the major summer haul-out sites. Profile photographs of the head and neck were matched using purpose-written software to generate a database of capture histories from 1995-2000. The haul-outs were grouped into seven areas. Darroch's method (20) for a two-sample capture-recapture census was adapted to estimate rates of movement between the areas. The majority of seals were estimated to remain within the same area, suggesting that Baltic gray seals exhibit a high degree of site fidelity during the summer, and that fidelity to a site lasts for more than one season.

    Full Text Available BACKGROUND: It seems generally accepted that targeted interventions in India have been successful in raising condom use between female sex workers (FSWs and their clients. Data from clients of FSWs have been under-utilised to analyse the risk environments and vulnerability of both partners. METHODS: The 2009 Integrated Biological and Behavioural Assessment survey sampled clients of FSWs at hotspots in Andhra Pradesh, Maharashtra and Tamil Nadu (n=5040. The risk profile of clients in terms of sexual networking and condom use are compared across usual pick-up place. We used propensity score matching (PSM to estimate the average treatment effect on treated (ATT of intervention messages on clients' consistent condom use with FSW. RESULTS: Clients of the more hidden sex workers who solicit from home or via phone or agents had more extensive sexual networks, reporting casual female partners as well as anal intercourse with male partners and FSW. Clients of brothel-based sex workers, who were the least educated, reported the fewest number/categories of partners, least anal sex, and lowest condom use (41%. Consistent condom use varied widely by state: 65% in Andhra Pradesh, 36% in Maharashtra and 29% in Tamil Nadu. Exposure to intervention messages on sexually transmitted infections was lowest among men frequenting brothels (58%, and highest among men soliciting less visible sex workers (70%. Exposure had significant impact on consistent condom use, including among clients of home-based sex workers (ATT 21%; p=0.001 and among men soliciting other more hidden FSW (ATT 17%; p=0.001. In Tamil Nadu no impact could be demonstrated. CONCLUSION: Commercial sex happens between two partners and both need to be, and can be, reached by intervention messages. Commercial sex is still largely unprotected and as the sex industry gets more diffuse a greater focus on reaching clients of sex workers seems important given their extensive sexual networks.

    This article focuses on considerations for natal females who present in the adolescent years with concerns related to their gender. They maybe individuals previously evaluated in their childhood years who have persisted with gender variance or gender identity disorder (GID) in DSM-IV, or they may be presenting for the first time in their adolescent years. The article discusses how to assess adolescents who come for evaluation and what treatments and other resources are available for them and their families. Where there seem to be differences between boys and girls with gender identity issues, they will be noted.

  4. Pre and post-natal antigen exposure can program the stress axis of adult zebra finches: evidence for environment matching.

    Merrill, Loren; Grindstaff, Jennifer L

    2015-03-01

    Both maternal exposure to stressors and exposure of offspring to stressors during early life can have lifelong effects on the physiology and behavior of offspring. Stress exposure can permanently shape an individual's phenotype by influencing the development of the hypothalamic-pituitary-adrenal (HPA) axis, which is responsible for the production and regulation of glucocorticoids such as corticosterone (CORT). In this study we used captive zebra finches (Taeniopygia guttata) to examine the effects of matching and mismatching maternal and early post-natal exposure to one of two types of antigens or a control on HPA axis reactivity in adult offspring. Prior to breeding, adult females were injected with lipopolysaccharide (LPS), keyhole limpet hemocyanin (KLH) or a control. Offspring of females in each of the three treatments were themselves exposed to LPS, KLH or a control injection at 5 and 28days post-hatch. When offspring were at least 18months of age, standardized capture and restraint stress tests were conducted to determine the impact of the treatments on adult stress responsiveness. We found significant interaction effects between maternal and offspring treatments on stress-induced CORT levels, and evidence in support of the environment matching hypothesis for KLH-treated birds, not LPS-treated birds. KLH-treated offspring of KLH-treated mothers exhibited reduced stress-induced CORT levels, whereas LPS-treated or control offspring of KLH-treated mothers exhibited elevated stress-induced CORT levels. Although the treatment effects on baseline CORT were non-significant, the overall pattern was similar to the effects observed on stress-induced CORT levels. Our results highlight the complex nature of HPA axis programming, and to our knowledge, provide the first evidence that a match or mismatch between pre and post-natal antigen exposure can have life-long consequences for HPA axis function.

    Gender-based violence has serious consequences for the psychological, physical, and sexual well-being of both men and women. Various gender roles, attitudes, and practices in South Africa create an environment that fosters submission and silence in females and hegemony and coercion in males. One of the expressions of this power inequity is a high prevalence of forced sex, which in its turn is associated with higher risk of HIV infection. This study therefore assessed potential gender differences in beliefs about forced sex and in prevalence of reported forced sex among high school students (N = 764) in KwaZulu-Natal. Results showed that significantly more boys were sexually active (26 %) than girls (12 %) and that boys experienced earlier sexual debut by over a year. Boys also held a more positive view about forced sex than girls since they associated it more often with signs of love, as an appropriate way to satisfy sexual urges, and as acceptable if the girl was financially dependent on the boy. The perception that peers and friends considered forced sex to be an effective way to punish a female partner was also more common among boys. On the other hand, boys were less knowledgeable about the health and legal consequences of forced sex, but no significant differences were found for other sociocognitive items, such as self-efficacy and behavioral intention items. Consequently, health education programs are needed to inform both boys and girls about the risks of forced sex, to convince boys and their friends about its inappropriateness and girls to empower themselves to avoid forced sex.

    The European perch is a species endowed with high adaptation capabilities as regards different environmental conditions. The aim of the study was to analyse the annual developmental cycle of ovaries of the European perch from the Oder river, Lake Dąbie and a drainage canal (Warm Canal) carrying post-cooling water from the Dolna Odra power plant (annual average water temperature in the canal is higher by 6-8°C than the water of the other sampling sites). Most of the female perch caught in the canal carrying post-cooling water had immature stage 2 gonads (delayed development of the gonads) and were smaller than the fish from the other sites. No traces of spawning in the form of deposed egg strings were found in the drainage canal. Adult individuals avoid high temperatures found in the Warm Canal. In April, in perch from all sites, ovaries with post-spawning oocytes were observed. The spawning season of the females lasted from the beginning of April until May. Stage 4 of gonad development, with oocytes in advanced vitellogenesis, was the longest and ranged from September through February.

    The sterile neutrino mechanisms for natal neutron stars kicks are re-analyzed. It is shown that the magnetic field strengths needed for a kick were underestimated essentially. Another mechanism with standard neutrinos is discussed where the outgoing neutrino flux in a supernova explosion with a strong toroidal magnetic field generation causes the field redistribution in "upper" and "lower" hemispheres of the supernova envelope. The resulting magnetic field pressure asymmetry causes the pulsar natal kick.

    Clients of female sex workers (CFSWs) are a bridge population for the spread of HIV and syphilis to low or average risk heterosexuals. Most studies have examined the point prevalence of these infections in CFSWs. Limited evidence suggests that older age CFSWs are at a higher risk of acquiring sexually transmitted diseases compared with younger clients. Thus, we sought to describe long-term trends in HIV, syphilis, and hepatitis C (HCV) to better understand how these infections differ by sex worker classification and client age. We also examined trends in HIV, syphilis, and HCV among categories of female sex workers (FSWs).We conducted serial cross-sectional studies from 2010 to 2015 in Guangxi autonomous region, China. We collected demographic and behavior variables. FSWs and their clients were tested for HIV, syphilis, and HCV antibodies. Positive HIV and syphilis serologies were confirmed by Western blot and rapid plasma regain, respectively. Clients were categorized as middle age (40-49 years) and older clients (≥50 years). FSWs were categorized as high-tier, middle-tier, or low-tier based on the payment amount charged for sex and their work venue. Chi-square test for trends was used for testing changes in prevalence over time.By 2015, low-tier FSWs (LTFSWs) accounted for almost half of all FSWs; and they had the highest HIV prevalence at 1.4%. HIV prevalence declined significantly for FSWs (high-tier FSW, P = 0.003; middle-tier FSWs; P = 0.021; LTFSWs, P preferred LTFSWs, especially older clients (81.9%).Our results suggest that HIV and syphilis infections are increasing in older clients who prefer LTFSWs. HIV and syphilis are likely increasing in Guangxi Province through heterosexual transmission.

    Full Text Available Since South Africa boasts a high biodiversity of frog species, a multispecies haemoparasite survey was conducted by screening the blood from 29 species and 436 individual frogs. Frogs were collected at three localities in sub-tropical KwaZulu-Natal, a hotspot for frog diversity. Twenty per cent of the frogs were infected with at least one of five groups of parasites recorded. Intraerythrocytic parasites comprising Hepatozoon, Dactylosoma, and viral or bacterial organisms, as well as extracellular parasites including trypanosomes and microfilarid nematodes were found. A significant difference (P < 0.01 in the prevalence of parasitaemia was found across species, those semi-aquatic species demonstrating the highest, followed by semi-terrestrial frog species. None of those species described as purely terrestrial and aquatic were infected. Hepatozoon and Trypanosoma species accounted for most of the infections, the former demonstrating significant differences in intensity of infection across species, families and habitat types (P = 0.028; P = 0.006; P = 0.007 respectively. Per locality, the first, the formally protected Ndumo Game Reserve, had the highest biodiversity of haemoparasite infections, with all five groups of parasites recorded. The other two sites, that is the area bordering the reserve and the Kwa Nyamazane Conservancy, had a lower diversity with no parasite infections recorded and only Hepatozoon species recorded respectively. Such findings could be ascribed to the anthropogenic impact on the latter two sites, the first by the rural village activities, and the second by the bordering commercial sugar cane agriculture. Future studies should include both morphological and molecular descriptions of the above parasites, as well as the identification of potential vectors, possibly clarifying the effects human activities may have on frog haemoparasite life cycles and as such their biodiversity.

    To achieve UNAIDS 90-90-90 targets, alternatives to conventional HIV testing models are necessary in South Africa to increase population awareness of their HIV status. One of the alternatives is oral mucosal transudates-based HIV self-testing (OralST). This study describes implementation of counsellor-introduced supervised OralST in a high HIV prevalent rural area. Cross-sectional study conducted in two government-run primary healthcare clinics and three Médecins Sans Frontières-run fixed-testing sites in uMlalazi municipality, KwaZulu-Natal. Lay counsellors sampled and recruited eligible participants, sought informed consent and demonstrated the use of the OraQuick(™) OralST. The participants used the OraQuick(™) in front of the counsellor and underwent a blood-based Determine(™) and a Unigold(™) rapid diagnostic test as gold standard for comparison. Primary outcomes were user error rates, inter-rater agreement, sensitivity, specificity and predictive values. A total of 2198 participants used the OraQuick(™) , of which 1005 were recruited at the primary healthcare clinics. Of the total, 1457 (66.3%) were women. Only two participants had to repeat their OraQuick(™) . Inter-rater agreement was 99.8% (Kappa 0.9925). Sensitivity for the OralST was 98.7% (95% CI 96.8-99.6), and specificity was 100% (95% CI 99.8-100). This study demonstrates high inter-rater agreement, and high accuracy of supervised OralST. OralST has the potential to increase uptake of HIV testing and could be offered at clinics and community testing sites in rural South Africa. Further research is necessary on the potential of unsupervised OralST to increase HIV status awareness and linkage to care. © 2016 John Wiley & Sons Ltd.

    Full Text Available This paper presents findings of a survey of optometric practices and practitioners in the KwaZulu-Natal (KZN province. Questions on demographics of practitioners, equipment, clinical practice andbusiness profile were included in the questionnaire. Also, issues that have the potential to impact on optometric practices were contained in the questionnaire and these include medical aid, advertising, continuous professional development (CPD and emigration. Of the 117 completed questionnaires, 55% were from females and 45% were from male practitioners. The respondents included 55% Indians, 27% Whites, 17% Blacks and 1% Coloureds. The majority of practices were located in urban areas (90% and rural areas (10%, and were mostly independent (67% and franchises (33%. Only a minority of the practices had major diagnostic equipment such as visual field analysers (33% and corneal topographers (7%. A significant proportion of the practitioners reported not routinely performing non-contact tonometry (45% and slit lamp examination (41% respectively. The majority (95% rated patient’s needs as a very important factor in their decision to prescribe an optical device. A significant proportion (38% of the practices had annual patient bases of above 33 000, with 35% having an average of 51-100 new patients per month.

  18. Assessing entrepreneurship perceptions of high school learners in Pietermaritzburg, KwaZulu-Natal

    Full Text Available Although South Africa achieved positive economic growth rates since the advent of democracy in 1994, the formal sector has not been able to absorb the annual increasing number of job-seekers on the market and solve the unemployment problem. The exercise of entrepreneurship, through business formations and expansions, is regarded as a vehicle for job creation and output expansion. According the Global Entrepreneurship Monitor (GEM reports, South Africa’s level of early stage total entrepreneurial activity (TEA is rather low relative to other countries at a similar level of development. This is partly owing to skills and resource limitations. If more individuals could realistically be exposed to practical entrepreneurship education at the secondary school level, South Africa’s base for entrepreneurial capacity can be enhanced. This study uses quasi logistic regression to examine the probability of secondary school learners, in Pietermaritzburg, the capital of Kwazulu-Natal province in South Africa, to start their own business in the future. It also probes the association between the socio-economic attributes of these learners and entrepreneurship. On the basis of a survey of 275 senior school learners from 5 schools, the regression results indicate that gender, ethnic background and having a role model as well as acquiring personal skills to run one’s own business are significant factors influencing an individual’s propensity to venture into small firm self-employment in the future. Black learners are perceived to have a significantly greater disposition to enter into business than other groups, and male scholars are found to have a greater probability of starting their own business than female. As potential entrepreneurs do not necessarily come exclusively from a business family background, the supply of effective entrepreneurship can be augmented, if more young individuals with the relevant skills endowment can start opportunity firms

    To evaluate the safety, technical feasibility, and complications of totally implanted central venous access ports (TIVAPs) in the upper arm, for comparison with trans-jugular chest ports in patients with breast cancer. In total, 223 consecutive female breast cancer patients who received a TIVAP in the upper arm or chest between July 2014 and February 2016 were included. All procedures were performed via a sonographic and fluoroscopic-guided approach using the Seldinger technique under local anesthesia. We reviewed the medical records to determine technical success, pain scale, early (≤30 days), and late (>30 days) complications. In total, 231 devices were implanted in the upper arms (n=176, 76%) and chests (n=55, 24%) of the patients. The mean age was 51.6±10.7 years (range 23-78 years; upper arm, 52.1±11.0 years; chest, 50.1±9.7 years, P>0.05). The mean implantation time for TIVAPs was 181.7±109.2 days (range, 9-460 days; upper arm 175.2±102.7 days; chest, 202.4±126.6 days, P>0.05), with 41,974 catheter-days. The technical success rate was 100%. Fourteen complications (6.1%) occurred in 14 patients (0.33/1000 catheter-days). There was no significant difference in complication-free survival for patients with upper arm TIVAPs and those with trans-jugular chest TIVAPs. The mean amount of 2% lidocaine, used as local anesthesia, was 3.3±1.7 ml and 14.5±4.1 ml for upper arm and chest TIVAPs, respectively. (Pupper arm is a safe procedure with a low rate of complications. Upper arm TIVAPs can be implanted with less pain compared with trans-jugular chest TIVAPs. Copyright © 2018 Elsevier Inc.

  1. Observations of feedback between protostars and their natal clouds

    Green, Joel D.

    2008-06-01

    In this thesis we explore the relationship between the formation of protostars, and the influence of protostellar outflows on their environment using Infrared Spectrograph onboard the Spitzer Space Telescope. First we introduce the modern understanding of protostellar development advanced by the IRS_Disks guaranteed time program. Next we explore the FU Orionis phenomenon, an IRS_Disks dataset of flaring stars undergoing a burst accretion event. Finally we present a suite of data on Herbig Haro flows in Cepheus A to determine whether protostellar outflows can dissociate a wide angle cavity in their natal cloud. We present 5-35 mm spectra, taken with the Infrared Spectrograph (IRS) on the Spitzer Space Telescope, of five FU Orionis objects: FU Ori, V1515 Cyg, V1057 Cyg, BBW 76, and V346 Nor. All but V346 Nor reveal amorphous silicate grains in emission at 10 mm and 20 mm, and show water-vapor absorption bands at 5.8 and 6.8 mm and SiO or possibly methane absorption at 8 mm. These absorption features closely match these bands in model stellar photospheres--signs of the gaseous photospheres of the inner regions of these objects' accretion disks. The continuum emission at 5-8 mm is also consistent with such disks, and, for FU Orionis and BBW 76, longer-wavelength emission may be fit by a model which includes moderate disk flaring. V1057 Cyg and V1515 Cyg have much more emission at longer wavelengths than the others, perhaps evidence of substantial remnant of their natal, infalling envelopes. This indicates that FU Orionis events can briefly raise outflow rates sufficiently high to dispel their surrounding envelopes and open swaths of the ambient medium via compression waves. Herbig Haro objects are small emission nebulae that signify the interaction between both broad and collimated outflows from young stellar objects and the ambient molecular cloud material. GGD37 is suspected to be an amalgamation of at least two superposed flows (including HH 168) traveling in

    Regular physical activity during puberty improves bone mass acquisition. However, it is unknown whether extreme intense training has the same favorable effect on the skeleton. We evaluated the bone mass acquisition in a unique cohort of world-class rhythmic gymnasts. A total of 133 adolescent girls and young women with a mean age of 18.7 ± 2.7 (14.4-26.7) years participated in this study: 82 elite rhythmic gymnasts (RGs) and 51 controls (CONs). Anthropometric variables and body composition were assessed, and all participants completed questionnaires on their general medical, menstrual, and training histories. Broadband ultrasound attenuation (BUA in decibels per megahertz) was determined by quantitative ultrasound at the heel. RGs presented lower weight (-8.5%, P rhythmic gymnastics appeared to have a beneficial effect on the bone health of a weight-bearing site. This effect was nevertheless modulated by the age of menarche. The high mechanical loading generated by this activity may counterbalance the negative effect of menstrual disorders.

    Few prospective studies have examined associations between breast cancer worry and screening behaviours in women with elevated breast cancer risks based on family history. Methods. This study included 901 high familial risk women, aged 23-71 years, from the Ontario site of the Breast Cancer Family Registry. Self-reported breast screening behaviours at year-one followup were compared between women at low (N=305), medium ( N=433), and high (N=163) levels of baseline breast cancer worry using logistic regression. Nonlinear relationships were assessed using likelihood ratio tests. Results. A significant non-linear inverted “U” relationship was observed between breast cancer worry and mammography screening (π=0. 034) for all women, where women at either low or high worry levels were less likely than those at medium to have a screening mammogram. A similar significant non-linear inverted “U” relationship was also found among all women and women at low familial risk for worry and screening clinical breast examinations (CBEs). Conclusions. Medium levels of cancer worries predicted higher rates of screening mammography and CBE among high-risk women

    We tested the hypothesis that sex-biased natal dispersal reduces close inbreeding in American black bears, a solitary species that exhibits nearly complete male dispersal and female philopatry. Using microsatellite DNA and spatial data from reproductively mature bears (>or= 4 years old), we examined the spatial genetic structure of two distinct populations in New Mexico from 1993 to 2000. As predicted, relatedness (r) and the frequency of close relationships (parent-offspring or full siblings) decreased with distance among female dyads, but little change was observed among male or opposite-sex dyads. Neighbouring females were more closely related than neighbouring males. The potential for inbreeding was low. Most opposite-sex pairs that lived sufficiently close to facilitate mating were unrelated, and few were close relatives. We found no evidence that bears actively avoided inbreeding in their selection of mates from this nearby pool, as mean r and relationship frequencies did not differ between potential and actual mating pairs (determined by parentage analysis). These basic patterns were apparent in both study areas despite a nearly two-fold difference in density. However, the sex bias in dispersal was less pronounced in the lower-density area, based on proportions of bears with male and female relatives residing nearby. This result suggests that male bears may respond to reduced competition by decreasing their rate or distance of dispersal. Evidence supports the hypothesis that inbreeding avoidance is achieved by means of male-biased dispersal but also indicates that competition (for mates or resources) modifies dispersal patterns.

    Little is known regarding factors implicated in early engagement and retention in HIV care among individuals not yet eligible for antiretroviral therapy (pre-ART) in sub-Saharan Africa. Identifying such factors is critical for supporting retention in pre-ART clinical care to ensure timely ART initiation and optimize long-term health outcomes. We assessed patients' pre-ART HIV care-related information, motivation, and behavioral skills among newly diagnosed ART-ineligible patients, initiating care in KwaZulu-Natal, South Africa. The survey was interviewer-administered to eligible patients, who were aged 18 years or older, newly entering care (diagnosed within the last six-months), and ineligible for ART (CD4 count > 200 cells/mm(3)) in one of four primary care clinical sites. Self-reported information, motivation, and behavioral skills specific to retention in pre-ART HIV-care were characterized by categorizing responses into those reflecting potential strengths and those reflective of potential deficits. Information, motivation, and behavioral skills deficits sufficiently prevalent in the overall sample (i.e.,≥30% prevalent) were identified as areas in need of specific attention through intervention efforts adapted to the clinic level. Gender-based differences were also evaluated. A total of 288 patients (75% female) completed structured interviews. Across the sample, eight information, eight motivation, and eight behavioral skills deficit areas were identified as sufficiently prevalent to warrant specific targeted attention. Gender differences did not emerge. The deficits in pre-ART HIV care-related information, motivation, and behavioral skills that were identified suggest that efforts to improve accurate information on immune function and HIV disease are needed, as is accurate information regarding HIV treatment and transmission risk prior to ART initiation.

    Full Text Available Abstract Background- Neonatal abdominal ultrasound is usually performed in Nigeria to investigate neonatal symptoms rather than as a follow up to evaluate fetal abnormalities which were detected on prenatal ultrasound. The role of routine obstetric ultrasonography in the monitoring of pregnancy and identification of fetal malformations has partly contributed to lowering of fetal mortality rates. In Nigeria which has a high maternal and fetal mortality rate, many pregnant women do not have ante-natal care and not infrequently, women also deliver their babies at home and only bring the newborns to the clinics for immunization. Even when performed, most routine obstetric scans are not targeted towards the detection of fetal abnormalities. The aim of the present study is to evaluate the benefit of routinely performing abdominal scans on newborns with a view to detecting possible abnormalities which may have been missed ante-natally. Methods- This was a longitudinal study of 202 consecutive, apparently normal newborns. Routine clinical examination and abdominal ultrasound scans were performed on the babies by their mother's bedside, before discharge. Neonates with abnormal initial scans had follow-up scans. Results- There were 108 males and 94 females. There were 12 (5.9% abnormal scans seen in five male and seven female neonates. Eleven of the twelve abnormalities were in the kidneys, six on the left and five on the right. Three of the four major renal anomalies- absent kidney, ectopic/pelvic kidney and two cases of severe hydronephrosis were however on the left side. There was one suprarenal abnormality on the right suspected to be a possible infected adrenal haemorrage. Nine of the abnormal cases reported for follow- up and of these, two cases had persistent severe abnormalities. Conclusions- This study demonstrated a 5.9% incidence of genito urinary anomalies on routine neonatal abdominal ultrasound in this small population. Routine obstetric USS

    Full Text Available OBJETIVO: Avaliar as diferenças sítio-ósseo dependentes no efeito das disfunções tireoidianas no fêmur e vértebras lombares de ratas. MÉTODOS: 33 ratas Wistar com dois meses de idade foram distribuídas em três grupos: eutireoideas (controle, hipotireoideas e hipertireoideas. Após 90 dias de tratamento para indução do hipo e hipertireoidismo, as ratas foram eutanasiadas, o sangue foi colhido para dosagem de T4 livre e os fêmures e as vértebras lombares (L1-L3 foram descalcificados e processados para análise da porcentagem de tecido ósseo trabecular. RESULTADOS: O grupo hipertireoideo apresentou porcentagem de tecido ósseo trabecular significativamente mais elevada na metáfise femoral, em comparação ao controle. Mas o hipertireoidismo não alterou a porcentagem de tecido ósseo trabecular na vértebra. O hipotireoidismo reduziu significativamente a porcentagem de tecido ósseo trabecular em comparação aos demais grupos nos segmentos 1-3 das vértebras lombares, mas não alterou a porcentagem de tecido ósseo trabecular no fêmur. CONCLUSÃO: O efeito do hipotireoidismo e do hipertireoidismo sobre a histomorfometria óssea é diferente e dependente do sítio ósseo.OBJECTIVE: Evaluating bone site-dependent differences in the effect of thyroid dysfunctions on the femur and lumbar vertebrae of female rats. METHODS: Thirty-three 2-month-old female wistar rats were distributed in three groups: euthyroid (control, hypothyroid and hyperthyroid. Ninety days after treatment for hypothyroidism and hyperthyroidism induction, the female rats were euthanized; the blood was collected for free T4 dosage and the femurs and segment 1-3 of the lumbar vertebrae were decalcified and processed for analysis of the trabecular bone percentage. RESULTS: The hyperthyroid group showed significantly higher trabecular bone percentage in the femoral metaphysis, in comparison with the control group. But the hyperthyroidism group did not increase the

    The current study constituted part of a larger, longitudinal, South African-based study, namely, The Road and Aircraft Noise Exposure on Children’s Cognition and Health (RANCH—South Africa). In the context of a multicultural South Africa and varying demographic variables thereof, this study sought to investigate and describe the effects of gender, socioeconomic status and home language on primary school children’s reading comprehension in KwaZulu-Natal. In total, 834 learners across 5 public schools in the KwaZulu-Natal province participated in the study. A biographical questionnaire was used to obtain biographical data relevant to this study, and the Suffolk Reading Scale 2 (SRS2) was used to obtain reading comprehension scores. The findings revealed that there was no statistical difference between males and females on reading comprehension scores. In terms of socioeconomic status (SES), learners from a low socioeconomic background performed significantly better than those from a high socioeconomic background. English as a First Language (EL1) speakers had a higher mean reading comprehension score than speakers who spoke English as an Additional Language (EAL). Reading comprehension is indeed affected by a variety of variables, most notably that of language proficiency. The tool to measure reading comprehension needs to be standardized and administered in more than one language, which will ensure increased reliability and validity of reading comprehension scores.

  14. Economic Activities, Illness Pattern and Utilisation of Health Care Facilities in the Rural Population of Kwazulu-Natal, South Africa

    Science.gov (United States)

    2009-01-01

    ABSTRACT Background The study was undertaken among the rural and black communities of the Uthungulu health district of the KwaZulu-Natal province, South Africa. Method A cross-sectional community-based descriptive study was conducted. A multi-stage sampling strategy was adopted to obtain a representative sample of the communities. Results The mean age of the population was 27 years and majority was female (54%). Among the adult population only 30% were educated, 19% were engaged in some form of economic activities while 9% were in the formal employment sector. The average monthly income per household was R1 301 (95% CI, R1 283; R1 308). The illnesses were reported by 27% of the total population over a period of one month. Notably higher rates of female individuals (29%) were sick compared to males (24%, p < 0.001). The rates of illnesses among adult females (39%) were also significantly higher than among males (31%, p < 0.009). Most of them (69%) attended primary health care (PHC) clinics for medical services, while 67% reported chronic conditions. Age (OR = 1.4), gender (OR = 0.711), education (OR = 0.64) and economic activities (OR = 1.9) were found to be associated with being ill or not. Conclusion The rural black communities are underdeveloped and deprived, which results in higher prevalence of illnesses; however, the utilisation of PHC facilities is comparatively higher than in the rest of the province and other parts of the country. Interventions to improve community health care services among the deprived population should be focused through public health strategies such as all-encompassing PHC that includes health promotion, education and basic essential amenities.

  15. Proximate influences on female dispersal in white-tailed deer

    Ultimate causes of animal dispersal have been hypothesized to benefit the dispersing individual because dispersal reduces competition for local resources, potential for inbreeding, and competition for breeding partners. However, proximate cues influence important features of dispersal behavior, including when dispersal occurs, how long it lasts, and direction, straightness, and distance of the dispersal path. Therefore, proximate cues that affect dispersal influence ecological processes (e.g., population dynamics, disease transmission, gene flow). We captured and radio-marked 277 juvenile female white-tailed deer (Odocoileus virginianus), of which 27 dispersed, to evaluate dispersal behavior and to determine proximate cues that may influence dispersal behavior. Female dispersal largely occurred at 1 year of age and coincided with the fawning season. Dispersal paths varied but generally were non-linear and prolonged. Physical landscape features (i.e., roadways, rivers, residential areas) influenced dispersal path direction and where dispersal terminated. Additionally, forays outside of the natal range that did not result in dispersal occurred among 52% of global positioning system (GPS)-collared deer (n = 25) during the dispersal period. Our results suggest intra-specific social interactions and physical landscape features influence dispersal behavior in female deer. Female dispersal behavior, particularly the lack of directionality, the semi-permeable nature of physical barriers, and the frequency of forays outside of the natal range, should be considered in regard to population management and controlling the spread of disease.

    Infertility, defined as 1 year of unprotected intercourse without conception, is becoming of increasingly important medical concern. Fertility in both the male and the female is at its peak in the twenties. Many couples today have postponed marriage and/or childbearing into their 30s until careers are established, but at that point fertility may be diminished. The current epidemic of venereal disease has been associated with an increasing incidence of tubal scarring. In addition, the use of intrauterine devices (IUDs) and birth control pills for contraception have let to later problems with pelvic inflammatory disease (PID) and ovulation disturbances. The problem of infertility intensifies as the number of babies available for adoption decreases. Therefore, it is estimated that approximately 10-20% of couples will eventually seek medical attention for an infertility-related problem. Fortunately, marked improvements in the results of tubal surgery are concurrently occurring secondary to refinements in microsurgical techniques, and many medical alternatives to induce ovulation are being developed. The male factor causes infertility in 30-40 % of couples, and the female factor is responsible in approximately 50% of couples. No cause is found in 10-20% of couples. This chapter discusses the role of coordinated imaging in the diagnosis and therapy of infertility in the female

    To quantify time from entry in HIV care until Antiretroviral therapy (ART) initiation and identify factors associated with ART initiation in rural KwaZulu-Natal, South Africa. Adults ≥16 years entering the decentralised Hlabisa ART programme between 2007 and 2011 were followed until June 2013. Median survival times to ART initiation from date of programme entry and from date of ART eligibility were estimated with Kaplan-Meier methods. Associated factors were evaluated in Cox regressions, censoring for deaths. Of 37 749 adults (71.6% female), 17 638 (46.7%) initiated ART. Nearly half (46.9%) met the CD4 criteria for treatment eligibility at programme entry. Among the 20 039 individuals not yet ART-eligible at entry, only 62.5% were retained in care with at least one further CD4 measurement, of whom 6688 subsequently became ART-eligible. Overall, 65.5% of the 24 398 ART-eligible individuals initiated ART over the study period. ART initiation was more likely in women (P CD4 count (P CD4 count at eligibility. In this rural programme, continuation of care remains challenging, especially in men and younger adults. ART initiation is more likely in those engaged prior eligibility than in those entering HIV care only late in their HIV disease. © 2014 John Wiley & Sons Ltd.

    The elemental uptake by edible seaweed Caulerpa racemosa (Sea grapes), a marine macroalgae (chlorophyta, green alga) grown richly along KwaZulu-Natal coastline. The total concentrations of seven elements, namely Mn, Fe, As, B, Ti, Zn and Hg in Caulerpa racemosa were monitored for a one-year cycle (June 2002 to May 2003) at four selected sampling sites spread over 150 km wide from North to South. The C. racemosa possess high arsenic, boron and titanium accumulating ability, but low iron uptake. A typical C. racemosa sample at Treasure Beach in the vicinity of Durban Metropolis in autumn contained Mn (5.2+/-ppm), Fe (0.21+/-0.01 ppm), As (8.5+/-0. ppm), B (1090+/-ppb), Ti (159+/-ppb), Zn (3.8+/-0.1 ppb), and Hg (189+/-ppb). The general trend found at all sites was high elemental concentrations in winter and a decrease in concentrations from winter to spring and summer. C. racemosa recorded highest mercury levels (>205 ppb) during the summer season at the Zinkwasi site. The arsenic speciation in four abundant seaweeds from the beaches of Indian Ocean in the KwaZulu-Natal coast is investigated. The speciation of arsenic in two rhodophyta seaweeds, Plocamium corallorhiza and Gelidium abbottiorum, and two chlorophyta seaweeds, Ulva lactuca and Caulerpa racemosa at four sampling sites during the summer of 2003, is elucidated. Caulerpa racemosa had highest total arsenic (in ppb) reaching (8850+/-200) at Zinkwasi, and the concentrations of the other arsenic species analysed are As (III) (194+/-10), As(V) (568+/-27), methylarsonic acid (494+/-22) and dimethylarsinic acid (373+/-12). In an indirect estimation, C. racemosa had 81+/-2% aresenosugars.

    To investigate how delayed introduction of sulfadoxine-pyrimethamine (Fansidar) and arthemeter-lumefantrine (Coartem) as first-line drugs for malaria in KwaZulu-Natal contributed to the reported epidemics of 1985-1988 and 1997-2001. Ecological study assessing the association between malaria incidence and the emergence and degree of resistance to chloroquine from 1982 to 1988 and to sulfadoxine-pyrimethamine from 1991 to 2001, when each was the first-line malaria treatment. The relative risk for malaria infection after the level of drug resistance reached 10% was 4.5 (95% CI: 4.0-5.2) in the chloroquine period and 5.9 (95% CI: 5.7-6.1) in the sulfadoxine-pyrimethamine period. In the chloroquine period, the relative risk of death from malaria was tenfold (95% CI: 1.3-78.1) and the case fatality doubled after drug resistance had reached 10%. The risk of death during the sulfadoxine-pyrimethamine period was 10.8 (95% CI: 5.9-19.2) and case fatality 1.8 times higher after drug resistance had reached 10%, than before. Malaria epidemics in KwaZulu-Natal, South Africa have been exacerbated by failing drug regimens. The establishment of sentinel sites for monitoring drug failure and the prompt adoption of guidelines based on World Health Organization standards in drug resistance should improve malaria control.

    Female rats given a single injection of testosterone propionate (TP) in the first few days of post-natal life exhibit post-pubertally, persistent vaginal oestrous, sterility, disordered secretion of gonadotrophins and modified patterns of sexual behaviour. The effects of TP on the incorporation of 14 C-uridine in the CNS of 5 and 61/2 day old litter mate triads consisting of male, female and TP treated female rats were investigated. Low resolution autoradiographs of serial sections of brain were prepared and analysed. A sexual dimorphism in cell nuclear size was found in the suprachiasmatic, arcuate and paraventricular nuclei of the hypothalamus. TP treatment resulted in an increase in nuclear size towards the male pattern in the latter two areas. A decrease in cell nuclear size was found in the ventromedial and suprachiasmatic nuclei. Neither sex differences nor changes following TP injection were detected in rate of incorporation of 14 C-uridine in any areas of the brain, although a significant (p<0.02) reduction in uridine incorporation in the adrenal of the female animal 24 hours after TP injection was demonstrated. The results suggested an immediate direct action of TP on the hypothalamus and peripheral tissues of the neonatal rat. (author)

    A total of 110 pediatric patients aged 1 mopth up to 12 yrs, were examined in a neuropathological clinic to study x-ray alterations of the pespipatary opqans ip children with natal traumas of the spine and spinal cord. Different forms of chest deformity, signs of paresis of the diaphragmatic cupola, that are frequent in such patients, have been revealed. These patients often develop pneumonia caused by insufficient diaphragmatic function. The frequency of the diaphragmatic nerve involvement in children with natal lesions is accounted for by the fact that at the level of the C4-segment of the spinal cord is located the spiral respiratory center that is responsible for respiratory movements in the natal period. Therefore, it seems likely that respiratory disorders of the peripheral type can occUr in children with natal traUma of the spine lumn and spinal cord. It has been found that alterations in the thoracic organs are mostly of neurological nature

  10. Autonomy, natality and freedom: a liberal re-examination of Habermas in the enhancement debate.

    Pugh, Jonathan

    2015-03-01

    Jurgen Habermas has argued that carrying out pre-natal germline enhancements would be inimical to the future child's autonomy. In this article, I suggest that many of the objections that have been made against Habermas' arguments by liberals in the enhancement debate misconstrue his claims. To explain why, I begin by explaining how Habermas' view of personal autonomy confers particular importance to the agent's embodiment and social environment. In view of this, I explain that it is possible to draw two arguments against germline enhancements from Habermas' thought. I call these arguments 'the argument from negative freedom' and 'the argument from natality'. Although I argue that many of the common liberal objections to Habermas are not applicable when his arguments are properly understood, I go on to suggest ways in which supporters of enhancement might appropriately respond to Habermas' arguments. © 2014 The Author.

    All available data regarding natality in Czechoslovakia (or the Czech Republic) before and after the Chernobyl accident are summarized. Data from the databases of the Czech Statistical Office and of the State Office for Nuclear Safety were used to analyze natality and mortality of children in the Czech Republic and to evaluate the relationship between the level of contamination and the change in the sex ratio at time of birth that was observed in some areas in November of 1986. Although the change in the ratio of newborn boys-to-girls ratio was statistically significant, no direct relationship between that ratio and the level of contamination was found. Statistically significant changes in the sex ratio also occurred in Czechoslovakia (or in the Czech Republic) in the past, both before and after the accident. Furthermore, no statistically significant changes in the rate of stillbirths and multiple pregnancies were observed after the Chernobyl accident

    Full Text Available In this paper I briefly discuss the development of the doctrine of legitimate expectation in South African law, which had left the way open for the Constitutional Court to develop a doctrine of substantive legitimate expectation in KwaZulu-Natal Joint Liaison Committee v MEC for Education, KwaZulu-Natal (KZN JLC. I then discuss the court's refusal to develop the doctrine in KZN JLC and analyse the approach adopted instead, which saw the court invoke rationality review to create a new legal mechanism for the enforcement of a unilateral, publicly promulgated promise by government to pay on broad public law grounds. I do so from the perspective of whether or not this creative approach amounted to the development of the doctrine by another name. I consider the implications of the creative approach in KZN JLC for the development of the doctrine of substantive legitimate expectation under administrative law in future. Finally I discuss how the creation of a new legal mechanism to enforce publicly promulgated promises to pay was "subversive of PAJA and the scheme in s 33 of the Constitution".

    To evaluate the association between pre-natal and post-natal exposure to pet ownership and lung function in children, a cross-sectional study named Seven Northeastern Cities (SNEC) study was conducted. In this study, children's lung function including the forced expiratory volume in 1 second (FEV 1 ), forced vital capacity (FVC), maximal mid-expiratory flow (MMEF), and peak expiratory flow (PEF) were measured by spirometers, and pet ownership situations were collected by questionnaire. Analyzed by multiple logistic regression and generalized linear modeling, we found that for all subjects, pet exposure in the first 2 years of life was significantly associated with lung function impairment of FVCpet exposure, the increased odds of lung function impairment ranged from 35% (aOR=1.35; 95%CI: 1.12, 1.62) for FVCpets, higher odds were observed among children with dogs. When stratified by gender, girls with current pet exposure were more likely to have lung function impairment than boys. It implies self-reported exposures to pets were negatively associated with lung function among the children under study. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  20. Challenges in the prenatal and post-natal diagnosis of mediastinal cystic hygroma: a case report

    Directory of Open Access Journals (Sweden)

    Nazir Sarfraz

    2008-08-01

    Full Text Available Abstract Introduction Cystic hygroma is a benign congenital neoplasm that mostly presents as a soft-tissue mass in the posterior triangle of the neck. Pure mediastinal lesions are uncommon; the vast majority are asymptomatic and are an incidental finding in adulthood. The diagnosis is often made intra- or postoperatively. Prenatal identification is exceptional and post-natal diagnosis also proves challenging. Case presentation We report one such case that was mistaken for other entities in both the prenatal and immediate post-natal period. Initial and follow-up antenatal ultrasound scans demonstrated a multicystic lesion in the left chest, and the mother was counselled about the possibility of her baby having a congenital diaphragmatic hernia. Initial post-natal chest radiographs were reported as normal. An echocardiogram and thoracic computed tomography scan confirmed a complex multiloculated cystic mediastinal mass. The working diagnoses were of a mediastinal teratoma or congenital cystic adenomatous malformation. At operation, the lesion was compressed by the left lung and was found to be close to the left phrenic nerve, which was carefully identified and preserved. After excision, histopathological examination of the mass confirmed the diagnosis of cystic hygroma. Postoperative dyspnoea was observed secondary to paradoxical movement of the left hemidiaphragm and probable left phrenic neuropraxia. This settled conservatively with excellent recovery. Conclusion Despite the fact that isolated intrathoracic cystic hygroma is a rare entity, it needs to be considered in the differential diagnosis of foetal and neonatal mediastinal masses, particularly for juxtadiaphragmatic lesions. The phrenic nerve is not identifiable on prenatal ultrasound imaging, and it is therefore understandable that a mass close to the diaphragm may be mistaken for a congenital diaphragmatic hernia because of the location, morphology and potential phrenic nerve compression

    2016-01-01

    1. Variation in post-natal growth rates is substantial among organisms and especially strong among latitudes because tropical and south temperate species typically have slower growth than north temperate relatives. Metabolic rate is thought to be a critical mechanism underlying growth rates after accounting for allometric effects of body mass. However, comparative tests on a large spatial scale are lacking, and the importance of metabolism for growth rates remains unclear both within and particularly across latitudes.

    Juvenile raptors often travel thousands of kilometers from the time they leave their natal areas to the time they enter a breeding population. Documenting movements and identifying areas used by raptors before they enter a breeding population is important for understanding the factors that influence their survival. In North America, juvenile Gyrfalcons (Falco rusticolus) are routinely observed outside the species' breeding range during the nonbreeding season, but the natal origins of these birds are rarely known. We used satellite telemetry to track the movements of juvenile Gyrfalcons during their first months of independence. We instrumented nestlings with lightweight satellite transmitters within 10 d of estimated fledging dates on the Seward Peninsula in western Alaska and in Denali National Park (Denali) in interior Alaska. Gyrfalcons spent an average of 41.4 ?? 6.1 d (range = 30-50 d) in their natal areas after fledging. The mean departure date from natal areas was 27 August ?? 6.4 d. We tracked 15 individuals for an average of 70.5 ?? 28.1 d post-departure; Gyrfalcons moved from 105 to 4299 km during this period and tended to move greater distances earlier in the tracking period than later in the tracking period. Gyrfalcons did not establish temporary winter ranges within the tracking period. We identified several movement patterns among Gyrfalcons, including unidirectional long-distance movements, multidirectional long-and shortdistance movements, and shorter movements within a local region. Gyrfalcons from the Seward Peninsula remained in western Alaska or flew to eastern Russia with no movements into interior Alaska. In contrast, Gyrfalcons from Denali remained in interior Alaska, flew to northern and western Alaska, or flew to northern Alberta. Gyrfalcons from both study areas tended to move to coastal, riparian, and wetland areas during autumn and early winter. Because juvenile Gyrfalcons dispersed over a large geographic area and across three

  9. Natal Dispersal in the North Island Robin (Petroica longipes: the Importance of Connectivity in Fragmented Habitats

    Full Text Available Natal dispersal is an important component in bird population dynamics and can influence the persistence of local and metapopulations. We examined natal dispersal in the North Island robin (Petroica longipes, a sedentary bird species distributed in a fragmented forest habitat on Tiritiri Matangi Island, New Zealand. Earlier studies have shown that the only dispersal phase in this species takes place when juveniles leave their natal patch, and that juveniles who fail to find suitable habitat do not survive their first winter. These findings suggest that natal dispersal behavior in this species is important for population viability. We found that juveniles were highly affected by the fragmentation of the forest habitat, with patch occupancy being positively correlated with degree of connectivity of the landscape. Most juvenile movements (52.1% were observed between patches that were separated by less than 20 m. Juvenile North Island robins were found in all forest habitat types, including young and open stands. This suggests that the juveniles are not dependent on old forest stands during their dispersal phase. Based on these findings, we suggest that management of this regionally-threatened species should focus not only on maintaining populations in occupied patches and increasing the habitat quality of these patches, but also on protecting existing forest patches acting as corridors and creating new forest habitat among patches. This would greatly increase the viability of the species' metapopulations by increasing dispersal success between both unoccupied patches and subpopulations. Additionally, increased connectivity between forest patches could also be expected to increase the probability of successful dispersal of other threatened native species, many of which are also sensitive to the high degree of fragmentation of their habitats.

    Full Text Available Este documento tiene como objetivo discutir el surgimiento de una nueva tipología residencial que se ha extendido en el sur de Natal / RN, los condominios llamado Club. Su principal característica es la apelación a los artículos de ocio más diversos, que son utilizados por los empresarios urbanos como una forma de crear un nuevo estilo de vida y un nuevo producto que se vende. La base teórica de este trabajo se basa en el enfoque heterodoxo de la coordinación espacial realizada por Pedro Abramo. Esta perspectiva considera el espacio urbano como un conjunto de inventario de viviendas que son ofrecidas por los empresarios urbanos. En general, el orden urbano y el ambiente residencial es incierto, porque sufren cambios derivados de la aparición de las innovaciones de espacio causadas por empresarios urbanos en busca de beneficios extraordinarios. En el caso de la zona sur de Natal, la construcción de carreteras principales que conectan esta zona de la ciudad al vecino municipio de Parnamirim, que ha sido el blanco de la abundancia del mercado inmobiliario de Natal. El ciclo de vida de los inventarios residenciales de la Zona Sur de Natal ha cambiado con el tiempo, desde el principio de la vivienda en grandes alojamientos para la producción de proyectos verticais. En la actualidad, un fenómeno nuevo que se plantea es la propagación de una nueva clasificación, los condominios club. Al ser un caso reciente en que los proyectos se encuentran todavía en fase de lanzamiento o de la construcción, el estudio se llevará a cabo mediante el análisis de marketing utilizadas por los empresarios urbanos para atraer a los consumidores a través de panfletos y folletos.

    Community family planning programmes in South Africa arose from the controversial apartheid history of controlling the African population while encouraging the growth of European migrant population. Post-apartheid population policies shifted away from population control to aligning policies to the global agenda that placed emphasis on the link between population and development. The focus on population and development polices in post-apartheid South Africa is on social equality, justice and peace rather than controlling sections of the population. Given the shift, this paper interrogates the conceptions of contraceptive use among rural communities in KwaZulu-Natal. Our primary objective is to understand the dynamics surrounding access to and use of family planning services in peri-urban and rural areas of KwaZulu-Natal. Using focus group data, the findings of the study suggest that different social categories interact with the family planning programmes differently. How teenagers and married women perceive the value of family planning differs. Gender differences regarding the use of condoms are also evident. The paper attempts to grapple with the non-use of condoms despite the knowledge that these prevent pregnancy and provide protection from sexually-transmitted diseases. The contribution of this paper lies in its identification of socio-cultural factors and the political economy underlying the different attitudes towards contraceptive use in rural KwaZulu-Natal.

    Many coral reef fish larvae spend days to months in the open ocean before settlement on coral reefs [1]. Early in development, larvae have limited swimming capabilities and will therefore be greatly affected by currents. This can potentially result in dispersal distances of tens of kilometers [2]. Nevertheless, up to 60 % of surviving larvae have been shown to return to their natal reefs [2]. To home, the larvae must develop strong swimming capabilities and appropriate orientation mechanisms. Most late-stage larval reef fish can, after being passively drifted for days to weeks, swim strongly [3], and Ostorhinchus doederleini larvae have been shown to use chemotaxis to identify their natal reef once in its vicinity [2] and a sun compass for longer distance orientation [4] during the day. But how do they orient at night? Here, we show that newly settled fish caught at One Tree Island (OTI) at the Capricorn Bunker Reef Group (Great Barrier Reef) can use geomagnetic compass information to keep a south-east heading. This behavior might help them return to their natal reef in the absence of any celestial cues at night. Copyright © 2016 Elsevier Ltd. All rights reserved.

    It is clear that the Belmont Pluton and the dykes are geochemically, isotopically and therefore, genetically distinct. The Belmont pluton is probably related to the garnet leucogranite phase of the Margate Complex. It is suggested that the dykes (∼ 965 Ma) are younger than the Belmont pluton (∼1055 Ma). The relatively low initial 87 Sr/ 86 Sr are typical of the granites intruded at ∼1000 Ma. The age of the dykes is comparable with the 951 ± 16 Ma (R o =.70320 ± 13) given for the Sezela pluton. The high R o (∼0.715) of the dykes is similar to other, minor granite sheets from southern Natal, and is compatible with an origin by late-stage melting of pre-existing radiogenic material. Both the dykes and the Sezela pluton are unequivocally younger than the D 3 deformation, whereas the young dates from the Oribi Gorge Suite are controversial. Thus, although it is possible that some of the minor, intrusive granitic sheets could yet be shown to be of Pan-African age, it is evident that no significant Pan-African magmatism or thermal overprinting has affected the Natal sector of the Namaqua-Natal-Maudheim belt. 1 fig., 7 refs

    Full Text Available Background: Substance use and psychiatric disorders cause significant burden of disease in low- and middle-income countries. Co-morbid psychopathology and longer duration of untreated psychosis (DUP can negatively affect treatment outcomes. Objectives: The study assessed substance use amongst adults with severe mental illness receiving services at a regional psychiatric hospital in KwaZulu-Natal (South Africa. We describe the prevalence and correlates of lifetime substance use and examine the association between substance use and DUP. Methods: A cross-sectional survey recruited adults diagnosed with severe mental illness and assessed lifetime and past 3-month substance use using the World Health Organization Alcohol, Smoking and Substance Involvement Screening Test. Regression analyses were conducted to determine associations between lifetime substance use (other than alcohol and tobacco and DUP as measured by the World Health Organization Encounter Form. Results: Amongst 87 participants, alcohol (81.6%, tobacco (75.6% and cannabis (49.4% were the most common substances reported for lifetime use. Risk of health-related problems (health, social, financial, legal and relationship of cannabis use was associated with younger age, single marital status and lower education. Adjusted regression analyses indicated that use of amphetamines and methaqualone is associated with longer DUP. Conclusions: Substance use is prevalent amongst psychiatric patients in KwaZulu-Natal and may contribute to longer DUP. Mental health services in this region should address co-morbid substance use and psychiatric disorders. Keywords: Substance Use; Psychosis; KwaZulu-Natal

    Full Text Available The aim of the study was to evaluate the outcome of the empowerment of rural women in relation to gender issues, power, and communication within the Zululand District of KwaZulu-Natal in South Africa after implementation of a four-year Primary Health Care project in partnership with the Provincial Department of Health, and two Schools of Nursing at the University of KwaZulu-Natal and McMaster University in Canada. This project is based on substantial evidence which reveals that rural women are being neglected to the extent that these women have missed out on opportunities for development. The reasons for this disempowerment of women, particularly rural women, are thought to be due to the feminisation of poverty, as well as female submission, educational deprivation, privacy of domestic violence, exploitation, domination by men and cultural oppression (patriarchy.A qualitative research approach was used. Focus group discussion was utilised as the data collection technique, and this was also applied during the collection of baseline data. An interview guide covered issues of concern in the communities and households, including what the women would, or had done about these, how they engaged in decision-making in their families, how they handled situations when there was a difference of opinion, and their awareness of, and ability to claim their rights, including control of their lives. The data was collected from six clinics, from groups of six to ten women in the predominantly rural Zululand District of KwaZulu-Natal.The project has revealed improvement in the women’s realisation of their rights, albeit limited, in communication, self-confidence, and reliance, including partnerships between Primary Health Care Nurses and women’s groups. The formation of women’s groups facilitated community development and participation in their own health, socio-economic and emotional development.The project suggests that such groups be encouraged and

  19. Spatial distributions of male and female strawberry poison frogs and their relation to female reproductive resources.

    2001-12-01

    In many species with a resource-based mating system, males defend resources to increase their attractiveness to females. In the strawberry poison frog, Dendrobates pumilio, suitable tadpole-rearing sites appear to be a limited resource for females. Territorial males have been suggested to defend tadpole-rearing sites to increase their access to females. In this study we investigate the spatial association between tadpole-rearing sites and the sexes as well as the spatial association of males and females. If strawberry poison frogs have resource defense polygyny, we expect males and females to be associated with tadpole-rearing sites and that females will deposit their offspring in tadpole-rearing sites inside the territories of their mates. To test this hypothesis, home range and core area sizes were calculated for both sexes and the association patterns were compared in two areas that differed in their abundance of tadpole-rearing sites. Home ranges and core areas of females were much larger than male home ranges. Females showed a clumped distribution in the vicinity of tadpole-rearing sites. Males were not clumped and were less associated with tadpole-rearing sites. Females generally did not use tadpole-rearing sites in the territory of their mates and we therefore conclude that males did not defend tadpole-rearing sites for females. Our data are consistent with the general assumption that female distribution is influenced by resource distribution and that male distribution depends on female distribution. Nevertheless, the distribution of D. pumilio females was also influenced by male spacing patterns. Males probably initially establish their core areas where female density is high and then females move among territories to sample males. Males compete vigorously for places with high female density, the defense of which is likely important for enhancing their mating success. In general, the spacing patterns did not differ between populations but the sex ratio was

    Juvenile survival and recruitment can be more sensitive to environmental, ecological and anthropogenic factors than adult survival, influencing population-level processes like recruitment and growth rate in long-lived, iteroparous species such as southern right whales. Conventionally, Southern right whales are individually identified using callosity patterns, which do not stabilise until 6–12 months, by which time the whale has left its natal wintering grounds. Here we use DNA profiling of skin biopsy samples to identify individual Southern right whales from year of birth and document their return to the species’ primary wintering ground in New Zealand waters, the Subantarctic Auckland Islands. We find evidence of natal fidelity to the New Zealand wintering ground by the recapture of 15 of 57 whales, first sampled in year of birth and available for subsequent recapture, during winter surveys to the Auckland Islands in 1995–1998 and 2006–2009. Four individuals were recaptured at the ages of 9 to 11, including two females first sampled as calves in 1998 and subsequently resampled as cows with calves in 2007. Using these capture-recapture records of known-age individuals, we estimate changes in survival with age using Cormack-Jolly-Seber models. Survival is modelled using discrete age classes and as a continuous function of age. Using a bootstrap method to account for uncertainty in model selection and fitting, we provide the first direct estimate of juvenile survival for this population. Our analyses indicate a high annual apparent survival for juveniles at between 0.87 (standard error (SE) 0.17, to age 1) and 0.95 (SE 0.05: ages 2–8). Individual identification by DNA profiling is an effective method for long-term demographic and genetic monitoring, particularly in animals that change identifiable features as they develop or experience tag loss over time.

    Full Text Available Black rhinoceroses (Diceros bicornis are endangered and the southern-central sub-species (Diceros bicornis minor is considered critically endangered. We assessed the reproductive lifehistories of black rhinoceroses in Hluhluwe–iMfolozi Park (HiP, KwaZulu-Natal, South Africa, to determine whether this historically important donor sub-population was meeting regional reproductive targets. Detailed life-history information for known individuals (n = 79–120 was used to investigate reproductive parameters between 1998 and 2013. Mean age at sexual maturity was 12 years, which exceeded a target period of 7 years and 5 months. The mean inter-calving interval was 3 years and 8 months – 8 months longer than the recommended 3 years. The poor population performance of the HiP black rhinoceroses could be a result of poor habitat quality, poor animal condition, females losing their first calves, predation of calves or a negative social effect of annual live-harvesting of the population. However, we believe that the estimated ecological carrying capacity of black rhinoceroses at HiP (a figure used to ascertain whether the population can be harvested at all may be incorrect, leading to the poor reproductive performance. We recommend that the accuracy of the ecological carrying capacity estimate be assessed as a matter of urgency and that a moratorium be placed on the live-harvesting of individuals until the estimate has been refined. Conservation implications: Our results provide key data which can be used to refine black rhinoceros breeding targets in South Africa and the region more broadly

    Full Text Available Background: The incidence and prevalence of multidrug–resistant tuberculosis (MDR TB in the province of KwaZulu-Natal, South Africa, are amongst the highest in the world. Previously, interventions have been largely biomedical based; however, there is growing opinion that interventions must include social aspects such as patient education and attitudes.Methods: This observational study assessed the knowledge and attitudes of 380 patients diagnosed with MDR TB at a centralised MDR TB unit in Durban. Data were collected using a questionnaire that was distributed to every third patient attending the outpatient MDR TB clinic. Data were collected over an 8-week period and analysed descriptively.Results: Just under half of the respondents had primary MDR TB. Most respondents were young, female unemployed and did not receive a social grant. Knowledge around diagnosis of MDR TB was generally adequate. There were important misconceptions about spread of the disease and duration of treatment. Most respondents received knowledge of MDR TB from healthcare workers. Some respondents received knowledge from friends, family and Sangomas and believed that the disease was caused by bewitchment or as a form of punishment.Discussion: The need for strengthening the role of primary care physicians in promoting education and providing support is highlighted. Further study is needed to investigate the high rate of primary MDR TB and to identify the unique challenges faced by women who have MDR TB. Future research could include the possibility of involving traditional healers in a contextually sensitive MDR TB education, training and support programme.

  3. Sexual signalling by females: do unmated females increase their signalling effort?

    Theory predicts that females should invest least in mate searching when young, but increase their effort with age if they remain unmated. Few studies have examined variation in female sexual signalling. Female Dawson's burrowing bees (Amegilla dawsoni) search for males by signalling their receptivity on emergence, but many leave the emergence site unmated and must attract males at feeding sites. Female bees prevented from mating on emergence had more extreme versions of cuticular hydrocarbon profiles that make them attractive to males, lending empirical evidence of adaptive shifts in female mating effort. © 2015 The Author(s) Published by the Royal Society.

    Full Text Available There is a growing recognition of the dangers of electoral violence. Yet, the theoretical foundation for systematic research and for adequate policy is still underdeveloped. This article aims to develop the theoretical understandings of strategies to manage and prevent electoral violence. This is accomplished by integrating research conducted within the two academic discourses on democratization and conflict management and also by drawing on the experiences from the conflict-ridden province KwaZulu-Natal in South Africa. The five strategies identified are monitoring, mediation, legal measures, law enforcement and self-regulating practices. In the article, the functions and mechanisms of the strategies are discussed. In addition, we analyse the limitations and usefulness of each of the strategies in turn and also provide suggestions on how to improve electoral security.Gewaltsame Auseinandersetzungen bei Wahlen werden zunehmend als Gefahr erkannt. Dennoch sind die theoretischen Grundlagen systematischer Forschungen zu diesem Phänomen, die zu angemessenen politischen Handlungsweisen beitragen könnten, immer noch ungenügend entwickelt. Dieser Beitrag zielt darauf ab, einen theoretischen Hintergrund für Strategien zum Umgang mit Gewalt bei Wahlen und zur Prävention zu entwickeln. Zu diesem Zweck kombinieren die Autorinnen Ergebnisse zweier Forschungsbereiche – der Demokratisierungsforschung und der Forschung zum Konfliktmanagement – und ziehen außerdem Erfahrungen aus der konfliktbeladenen südafrikanischen Provinz KwaZulu-Natal heran. Sie identifizieren fünf Strategien: Monitoring, Mediation, gesetzliche Maßnahmen, Sanktionierung und Selbsthilfepraktiken. Die Autorinnen diskutieren die Wirkungsweisen und Erfolgsaussichten, aber auch die Grenzen dieser Strategien und machen einige konkrete Vorschläge zur Erhöhung der Sicherheit bei Wahlen.

    Melatonin administered during adulthood induces beneficial effects on cognition and neuroprotection in the Ts65Dn (TS) mouse model of Down syndrome. Here, we investigated the effects of pre- and post-natal melatonin treatment on behavioral and cognitive abnormalities and on several neuromorphological alterations (hypocellularity, neurogenesis impairment and increased oxidative stress) that appear during the early developmental stages in TS mice. Pregnant TS females were orally treated with melatonin or vehicle from the time of conception until the weaning of the offspring, and the pups continued to receive the treatment from weaning until the age of 5 months. Melatonin administered during the pre- and post-natal periods did not improve the cognitive impairment of TS mice as measured by the Morris Water maze or fear conditioning tests. Histological alterations, such as decreased proliferation (Ki67+ cells) and hippocampal hypocellularity (DAPI+ cells), which are typical in TS mice, were not prevented by melatonin. However, melatonin partially regulated brain oxidative stress by modulating the activity of the primary antioxidant enzymes (superoxide dismutase in the cortex and catalase in the cortex and hippocampus) and slightly decreasing the levels of lipid peroxidation in the hippocampus of TS mice. These results show the inability of melatonin to prevent cognitive impairment in TS mice when it is administered at pre- and post-natal stages. Additionally, our findings suggest that to induce pro-cognitive effects in TS mice during the early stages of development, in addition to attenuating oxidative stress, therapies should aim to improve other altered processes, such as hippocampal neurogenesis and/or hypocellularity.

    Full Text Available However significant the legacy of former segregational policies in the spatial organisation of South African cities, it is important to include other basic spatial structures that have often been minimised. That is the aim of this paper. The towns in KwaZulu-Natal province provide a strong illustration of this point. The urban entities in the province can be differentiated by several criteria – either historical or contemporary – that are not always related to apartheid policy. The towns are underpinned by basic structures that organise the province. These structures are determined not only by racial discrimination, but also by economics. Recent developments seem to reinforce this trend.

    Severe coastal erosion occurred along the KwaZulu-Natal coastline between mid-May and November 2011. Analysis of this erosion event and comparison with previous coastal erosion events in 2006/2007 offered the opportunity to extend the understanding of the time and place of coastal erosion strikes. The swells that drove the erosion hotspots of the 2011 erosion season were relatively low (significant wave heights were between 2 m and 4.5 m) but of long duration. Although swell height was import...

    Rb-Sr data are presented for a number of intrusive lithologies from the Scottburgh area of southern Natal. Dates obtained from these units range from ∼ 900 Ma to ∼ 1100 Ma with initial 87 Sr/ 86 Sr in the range ∼ 0,7026 to > 0,709 and are similar to dates obtained elsewhere in southern Natal. These dates, together with known field relationships, indicate that deformation of the supracrustal gneisses first occurred prior to ∼ 1089 Ma whereas the major metamorphic and tectonic episode (M 2 /D 2 - cause of the pervasive E-W tectonic fabric) occurred at ∼ 1000 Ma. D 3 was complete by ∼ 951 Ma. Pb isotope data provide insufficient spread to assist in dating the lithologies considered but do provide additional constraints on the genetic history of this sector of the Namaqua-Natal Belt. 26 refs., 10 figs., 6 tabs

    Malaria is the most contagious global concern. As a public health problem with outbreaks, affect the quality of life and economy, also could lead to death. Therefore, this research is to forecast malaria cases with climatic factors as predictors in Mandailing Natal Regency. The total number of positive malaria cases on January 2008 to December 2016 were taken from health department of Mandailing Natal Regency. Climates data such as rainfall, humidity, and temperature were taken from Center of Statistic Department of Mandailing Natal Regency. E-views ver. 9 is used to analyze this study. Autoregressive integrated average, ARIMA (0,1,1) (1,0,0)12 is the best model to explain the 67,2% variability data in time series study. Rainfall (P value = 0.0005), temperature (P value = 0,0029) and humidity (P value = 0.0001) are significant predictors for malaria transmission. Seasonal adjusted factor (SAF) in November and March shows peak for malaria cases.

Theimportance and value of school-based interventions in children has been identified in South Africa (SA. Although oral health strategiesinclude integrated school-based interventions, there is a lack of published evidence on whether these strategies have been translated intopractice and whether these programmes have been evaluated.Objective. To assess the efficiency and sustainability of the toothbrushing programme implemented at health-promoting schools inKwaZulu-Natal Province, SA.Methods. A mixed-methods approach was used for this study, conducted at 23 health-promoting schools in KwaZulu-Natal using focusgroup discussions. Triangulation was used for evaluation.Results. The intervention implemented had created awareness of oral health for learners, educators and parents. Findings in this studyindicate that although there were benefits obtained from this school-based intervention, many challenges, such as time constraints, largeclasses and a lack of adequate resources and funding, affected the sustainability of the programme.Conclusion.The school setting has the potential to deliver integrated preventive and promotive programmes provided they are supportedby adequate funding and resources.

    Aim: The way provincial or regional growth depends on infrastructure is investigated in this article and it is applied to data from KwaZulu-Natal province, as an illustration. Setting: This study investigates the extent to which infrastructure in KwaZulu-Natal province in South Africa leads towards economic growth of the province. Methods: From a theoretical framework, this article develops an endogenous growth model, which investigates the association between provincial public capital stock expenditure and economic growth. Data series for public capital formation are first developed to apply in this study and others to follow. Econometric techniques are then employed, using quarterly data between 2001 and 2015, to assess the set hypothesis that growth in expenditure on public capital leads to national economic growth. Results: The empirical results support the argument of a positive relationship between provincial capital stock and economic growth in the long-term. The findings also suggests that the long-term causality or effect fades over time, albeit slowly. Conclusion: The nature and statistical significance of the long-term equilibrium relationship seems to be ambiguous at best. Some evidence of an equilibrium relationship in the short-term was, however, also observed. In conclusion, there also seems to be some causality between provincial capital stock and provincial gross domestic product in the short-run.

    Despite the development of context-specific guidelines, cryptococcal meningitis (CCM) remains a leading cause of death amongst HIV-infected patients. Results from clinical audits in routine practice have shown critical gaps in clinicians' adherence to recommendations regarding the management of CCM. The aim of this study was to review the acute management of CCM at an urban district hospital in KwaZulu-Natal, South Africa with a view to making recommendations for improving care. An urban district hospital in KwaZulu-Natal, South Africa. A retrospective audit was performed on clinical records of all patients (age > 13 years) admitted to the hospital with a diagnosis of CCM between June 2011 and December 2012. Measurement of cerebrospinal fluid opening pressure at initial lumbar puncture (LP) was done rarely and only 23.4% of patients had therapeutic LPs. The majority of patients (117/127; 92.1%) received amphotericin B, however, only 19 of the 117 patients (16.2%) completed the 14-day treatment target. Amphotericin B-toxicity monitoring and prevention was suboptimal; however, in-patient referral for HIV counselling and testing was excellent. The quality of care of CCM based on selected process criteria showed gaps in routine care at the hospital despite the availability of context-specific guidelines. An action plan for improving care was developed based on stakeholders' feedback. A repeat audit should be conducted in the future in order to evaluate the impact of this plan and to ensure that improvements are sustained.

    Full Text Available Background: KwaZulu-Natal province began implementation of voluntary medical male circumcision (VMMC as an integral part of its HIV infection prevention strategy that includes other programmes such as HIV counselling and testing (HCT, screening and treatment of sexually transmitted infections and tuberculosis, and other sexual and reproductive health services. This followed randomised controlled trials that showed up to 60% HIV infection risk reduction amongst circumcised men. Implementation of the strategy occurred despite absence of knowledge of operational barriers and its acceptability to health care workers (HCWs. Objectives: The study aimed to explore HCWs’ perspectives of and barriers to strategy implementation at public sector health facilities to inform implementation policy. Method: A purposive quota sampling method was used to select HCWs for focus group discussions at three study sites. Participants were asked open-ended questions using an interview schedule based on a literature review to explore acceptability of and perceptions regarding provision of the strategy. Thematic analysis was conducted. Results: Acceptability of the strategy was high amongst the participants; however, there was limited knowledge of some key concepts of the strategy, personnel role confusion, missed opportunities for client recruitment, and infrastructural constraints. Negative perceptions included beliefs that VMMC would discourage condom use and cause stigma associated with non-circumcision of HIV-positive males, with perceptions of sexual behavioural disinhibition in circumcised men. Conclusion: There is a need to engage further with stakeholders if implementation of VMMC is to be successful. More training and support needs to be provided to HCWs at public sector facilities.

    The portion of Brazilian continental margin located between the Pernambuco Shear Zone (ZCPE) and Touros High, enclosing Natal Platform and Paraiba basin, NE Brazil, presents a thin sedimentary cover represented by Neo- Cretaceous deposits, over an elevated basement. In this zone the narrow platform ends abruptly against the ocean plate, forming a scarped slope. This area corresponds to the Transverse zone of Northeast Brazil (TZN) limited by two extensive transcurrent E-W shear zones that acted as accommodation zones for the strain produced by the advance of the southern and northern rift branches. During the Aptian, the rift suffered a NE deflection and contoured the Borborema Province and the TZN. The resistance of this block to the rift advance generated a prominent and elevated region into the Atlantic gulf which resulted in the absence of rift deposition over the Brazilian margin and its deviation to the African side. The model suggested by this paper denominates this area as the 'exception zone' of the Brazilian margin, which possess a poor petroliferous potential and need to be separated from the sector corresponding to the Pernambuco basin, located to south of ZCPE, representing the last piece of margin before the rift deflection and possessing an important petroliferous potential.

    Transsexualism is characterized by feelings of incongruity between one's natal sex and one's gender identity. It is unclear whether transsexual individuals have a body image that is more congruent with their gender identity than their sex assigned at birth (natal sex) and, if so, whether there are contributions from perceptual dysfunctions. We compared 16 pre-hormone treatment female-to-male transsexual (FtM) individuals to 20 heterosexual female and 20 heterosexual male controls on a visual identification task. Participants viewed photographs of their own body that were morphed by different degrees to bodies of other females or males, and were instructed to rate "To what degree is this picture you?" We also tested global vs. local visual processing using the inverted faces task. FtM differed from both control groups in demonstrating higher self-identification ratings for bodies morphed to the sex congruent with their gender identity, and across a broad range of morph percentages. This difference was more pronounced for longer viewing durations. FtM showed reduced accuracy for upright faces compared with female controls for short duration stimuli, but no advantage for inverted faces. These results suggest different own body identification in FtM, consisting of a relatively diffuse identification with body images congruent with their gender identity. This is more likely accounted for by conscious, cognitive factors than perceptual differences.

    We investigated the use of third-generation (3G) mobile communications to provide telehealth services in remote health clinics in rural KwaZulu-Natal, South Africa. We specified a minimal set of services as our use case that would be representative of typical activity and to provide a baseline for analysis of network performance. Services included database access to manage chronic disease, local support and management of patients (to reduce unnecessary travel to the hospital), emergency care (up to 8 h for an ambulance to arrive), e-mail, access to up-to-date information (Web), and teleclinics. We made site measurements at a representative set of health clinics to determine the type of coverage (general packet radio service [GPRS]/3G), its capabilities to support videoconferencing (H323 and Skype™ [Microsoft, Redmond, WA]) and audio (Skype), and throughput for transmission control protocol (TCP) to gain a measure of application performance. We found that none of the remote health clinics had 3G service. The GPRS service provided typical upload speed of 44 kilobits per second (Kbps) and download speed of 64 Kbps. This was not sufficient to support any form of videoconferencing. We also observed that GPRS had significant round trip time (RTT), in some cases in excess of 750 ms, and this led to slow start-up for TCP applications. We found audio was always so broken as to be unusable and further observed that many applications such as Web access would fail under conditions of very high RTT. We found some health clinics were so remote that they had no mobile service. 3G, where available, had measured upload speed of 331 Kbps and download speed of 446 Kbps and supported videoconferencing and audio at all sites, but we frequently experienced 3G changing to GPRS. We conclude that mobile communications currently provide insufficient coverage and capability to provide reliable clinical services and would advocate dedicated wireless services where reliable

    Natal dispersal is a key life history trait for the evolution and adaptation of wild populations. Although its evolution has repeatedly been related to the social and environmental context faced by individuals, parent-offspring regressions have also highlighted a possible heritable component. In this study, we explore heritability of natal dispersal, at the scale of the sub-Antarctic Possession Island, for a large-scale foraging seabird, the Wandering albatross Diomedea exulans, exploiting a pedigree spanning over four decades and a maximum of four generations. The comparison of three different methods shows that heritability on the liability scale can vary drastically depending on the type of model (heritability from 6% to 86%), with a notable underestimation by restricted maximum likelihood animal models (6%) compared to Bayesian animal models (36%). In all cases, however, our results point to significant additive genetic variance in the individual propensity to disperse, after controlling for substantial effects of sex and natal colony. These results reveal promising evolutionary potential for short-scale natal dispersal, which could play a critical role for the long-term persistence of this species on the long run. © 2011 The Authors.

    Lack of access to nutritious and balanced diets remains a major impediment to the health and well-being of people living in rural areas. The study utilizes a qualitative systematic approach to conduct an environmental scan and review of scientific literature of studies conducted in South Africa, specifically KwaZulu-Natal (KZN). Availability and access to nutritious, diverse and balanced diets were identified as key constraints for achieving food and nutrition security as well as for human health and well-being. This has led to both under- and over-nutrition, with the former, in particular stunting, affecting children under 5 years. A high incidence of over-nutrition, both overweight and obesity, was observed among black African females. In South Africa, poor people rely mostly on social grants and cannot afford a balanced diet. Under these circumstances, agriculture could be used to increase availability and access to diverse and nutritious foods for the attainment of a balanced diet. The wider use of traditional vegetable crops and pulses could improve availability and access to healthy and locally available alternatives. The promotion of household and community food gardens, and the use of nutrient dense crops with low levels of water use, i.e., high nutritional water productivity, offers prospects for addressing malnutrition in poor rural areas.

    In South Africa (SA), >4,000 women die annually of cervical cancer, a disease caused by the human papillomavirus (HPV). Infections caused by certain genotypes of HPV increase the risk of cervical cancer. HIV-infected women in particular are more likely to have persistent HPV infection, with higher-risk genotypes. In SA, two vaccines (HPV quadrivalent (types 6, 11, 16, and 18) vaccine, recombinant (Gardasil) and HPV bivalent (types 16 and 18) vaccine, recombinant (Cervarix)) are currently registered for the prevention of HPV-related disease. In the past, there have been significant challenges to achieving high coverage and uptake of vaccination–contributory factors include cost and lack of awareness. An HPV demonstration project among schoolgirls in rural KwaZulu-Natal showed that high vaccine uptake is achievable. In 2014, the National Department of Health launched the national HPV vaccination programme among female learners attending public schools. Awareness of HPV vaccination among healthcare providers, education of parents, teachers and learners, and avoidance of missed opportunities for vaccination are vital to the success of the programme. Primary healthcare practitioners may play an important role in cervical cancer prevention by identifying and offering vaccination to girls who miss the opportunity to be vaccinated at school. HPV vaccination should be considered as one arm of a comprehensive programme of cervical cancer prevention and control.

    Cervical cancer is linked to infection of the cervix by oncogenic human papillomavirus (HPV) subtypes. The quadrivalent Gardasil vaccine (against HPV types 6, 11, 16, 18), recommended in girls 9 - 12 years of age, has been shown to be safe, immunogenic and efficacious, with minimal or no side-effects. To demonstrate the capacity of school health teams to carry out vaccinations within a school environment. To assess the uptake of 3 doses of the vaccine, document lessons learnt and provide recommendations for a national rollout of school-based HPV vaccination for learners. Female learners (age 9 - 12 years) from 31 primary schools in Nongoma and Ceza districts (KwaZulu-Natal province, South Africa) were identified for inclusion in the vaccination programme. The 3 doses of vaccine were administered by existing school health teams. Education and training sessions were held with all stakeholders: provincial departments of health and education; school health teams; primary healthcare nurses; hospital doctors and nurses; private practitioners; school principals, teachers and governing bodies; parents; and community and traditional leaders. The overall uptake of the vaccine was found to be high: 99.7%, 97.9% and 97.8% for the first, second and third doses respectively (N = 963). No adverse events were attributed to the HPV vaccine. This project demonstrated the successful implementation of HPV vaccination among learners (ages 9 - 12 years) using school health teams.

    The potential reproductive and developmental toxicity of the synthetic oligodeoxynucleotide (ODN) CpG 7909, a component of GSK's AS15 immunostimulant, was examined in rat and rabbit studies following intermittent intramuscular injections. Previous studies using subcutaneous and intraperitoneal injections in mice, rats and rabbits revealed that CpG ODNs induced developmental effects. To analyze the safety signal, GSK conducted additional animal studies using the intended clinical route of administration. CpG 7909 injections were administered intramuscularly to rats or rabbits 28 and 14days before pairing, on 4 or 5 occasions during gestation, and on lactation day 7. The No Observed Adverse Effect Level for female fertility, embryo-fetal and pre- and post-natal development was 4.2mg/kg in both species, approximately 500-fold higher than the anticipated human dose. In conclusion, the anticipated risk to humans is considered low for sporadic intramuscular exposure to CpG 7909. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

    Decreased natality resulting from nutritional stress is one hypothesized mechanism for declines of Steller sea lions (SSLs; Eumetopias jubatus) in western Alaska, but little is known of the winter foraging habitats or behavior of adult females. To address this critical data need, adult female Steller sea lions were chemically immobilized and tagged with Fastloc® GPS satellite transmitters during the fall at Southeast Alaska (SEAK) during 2010 (n=3), and the central and western Aleutian Islands (AI) from 2011-2014 (n=9). To identify habitat features of biological importance to these animals, location data were processed with a continuous-time correlated random walk model and kernel density estimates of predicted locations were used to compute individual-based utilization distributions. Kernel density estimates and diving behaviors (i.e. mean, maximum, and frequency of dive depths) were examined with respect to a series of static and dynamic environmental variables using linear mixed-effects models. Habitat use varied within and among individuals, but overall, all response variables were significantly related to a combination of the predictor variables season, distance to nearest SSL site, bathymetric slope, on/off shelf, sea surface temperature, sea surface height, proportion of daylight, and some interaction effects (P≤0.05). The habitat use of SSL from SEAK was consistent with previous reports and reflected the seasonal distribution of predictable forage fish, whereas SSL from the AI used a variety of marine ecosystems and habitat use was more variable, likely reflecting specific prey behaviors encountered in different areas. These results have improved our understanding of the habitat features necessary for the conservation of adult female SSL and have been useful for reviewing designated critical habitat for Steller sea lions throughout the U.S. range.

    Full Text Available Centralization of municipal procurement in the KwaZulu-Natal Province is faced with several challenges. There were two aims for this study: to identify factors influencing municipal procurement and to design a model of the factors influencing municipal procurement, in an attempt to improve the understanding of municipal procurement. The proposed model is based on sound theoretical frameworks like knowledge management theory and the application of theory and practice ethics as well as the secondary data. The study found that the biographic factors as well as internal and external factors have strong influences on the success or failure of municipal procurement. The significance of these factors formed the basis for a proposed model and is subject to further experiments by other scholars.

  4. Neutron star natal kicks and the long-term survival of star clusters

    We investigate the dynamical evolution of a star cluster in an external tidal field by using N-body simulations, with focus on the effects of the presence or absence of neutron star natal velocity kicks. We show that, even if neutron stars typically represent less than 2 per cent of the total bound mass of a star cluster, their primordial kinematic properties may affect the lifetime of the system by up to almost a factor of 4. We interpret this result in the light of two known modes of star cluster dissolution, dominated by either early stellar evolution mass-loss or two-body relaxation. The competition between these effects shapes the mass-loss profile of star clusters, which may either dissolve abruptly (`jumping'), in the pre-core-collapse phase, or gradually (`skiing'), after having reached core collapse.

    This study examines variations in ante-natal care (ANC) and family planning in Krakor, Pursat, Cambodia between 1996 and 1998. Population-based survey interviews were conducted with a total of 291 women in 1996 and 211 women in 1998. An intervention strategy designed to enhance the skills and roles of Health Centre staff, Village Health Volunteers (VHVs) and Traditional Birth Attendants (TBAs) was conducted. Over this timeframe, reported ANC access increased from 37% to 47%. Most women delivered their last child at home, usually assisted by a TBA. Few women practiced family planning, despite the fact that most reported that they did not want any further children. A range of reasons for not practicing family planning were found to be highly significant, including the lack of available services (pCambodia.

    Full Text Available This article reports on a descriptive study aimed at exploring the perceptions of student nurses about the past, present and future of the discipline. In-depth interviews with 12 students from KwaZulu- Natal were transcribed and analysed. Students showed a realistic appraisal of the discipline. They valued the essence of the profession, and were positive about their work and their training. They felt, however that nurses are not treated well by others, that the working conditions are poor and the quality of care often bad. They saw their current role as more autonomous than in the past, and saw the nurse as moving more into the community, becoming more specialised, and more entrepreneurial in future. They saw the challenges of the future in the areas of quality of care, improving training, recognition of the profession, and management, and dealing with the problem of HIV/AIDS.

    The accelerated aging of the Brazilian population will certainly increase the number of institutionalized elderly. Based on this focus, this descriptive and exploratory study was carried out at three asylum institutions in Natal (RN), Brazil, with a view to characterizing the elderly living there, as well as identifying the socioeconomic and health problems and causes that took them to the asylum. The sample consisted of 30% of the total number of elderly in each asylum. These are philanthropic institutions and give shelter to poor elderly persons. Results showed that the three institutions' socioeconomic and health characteristics were similar to what is found in literature, with few financial conditions, family contact marked by conflict, lack or absence of leisure activities, precarious health, restricted medical and nursing care and absence of private health plans. Our reflections on the socioeconomic and health conditions of these persons led to the conclusion that public bodies need to take actions to safeguard their civil rights.

    Researchers aimed to determine the effects of a teenage pregnancy (TP) prevention program for 816 high school students attending 16 KwaZulu-Natal, South African schools through a randomized control trial. Data were collected at baseline and at the 8-month follow-up in 2009. Results were calculated using multivariate analyses of program effects employing Mplus 6, and indicated significantly healthier attitudes, including intentions to abstain from sex whilst at school, plans to communicate with partners about teenage pregnancy, and increased reports of condom use. Researchers thus provide some support for the effectiveness of a TP prevention program that should be further strengthened in a comprehensive approach that includes schools and families.

    Background. Although pregnancy is a recognized risk factor for severe influenza infection, the effect of influenza on miscarriages and births remains unclear. We examined the relationship between influenza and birth rates during the 1918 pandemic in the United States, Denmark, Sweden, and Norway...... of peak pandemic exposure and depressions in birth rates, and identified pregnancy stages at risk of influenza-related miscarriage. Results. Birth rates declined in all study populations in spring 1919 by a mean of 2.2 births per 1000 persons, representing a 5%–15% drop below baseline levels (P ...). The 1919 natality depression reached its trough 6.1–6.8 months after the autumn pandemic peak, suggesting that missing births were attributable to excess first trimester miscarriages in ∼1 in 10 women who were pregnant during the peak of the pandemic. Pandemic-related mortality was insufficient to explain...

    Full Text Available Resumo Pouco explorado pela literatura, os deslocamentos diários casa-escola refletem uma incoerência espacial entre a distribuição da população em idade escolar e os estabelecimentos de ensino de educação básica (nível médio em Natal, RN. Neste trabalho exploraremos o perfil dos comutadores (estudantes a partir de um recorte político-administrativo intramunicipal. Dessa forma foi possível captar os fluxos diários de estudantes entre os bairros do município de Natal. Para isso, utilizamos o conceito de espaço de vida como embasamento teórico e o banco de dados do Censo Escolar 2012. Assim, relacionando as informações referentes à localidade de residência e de estudos dos alunos, verificou-se a relação entre o deslocamento para estudo e o desempenho escolar medido através do indicador de distorção idade-série em um modelo de regressão logística. Entre os resultados encontrados identificou-se que a chance de um aluno ter um bom rendimento escolar não está relacionada com a proximidade de sua residência da escola. Nesse sentido, a dinâmica da população em termos de distribuição escolar e de alunos pode representar aspectos importantes para a gestão urbana e a oferta de serviços educacionais, sobretudo em um contexto no qual as tendências demográficas apontam para uma redução expressiva da população em idade escolar nos próximos anos.

  13. O discurso do risco e o aconselhamento genético pré-natal

    Directory of Open Access Journals (Sweden)

    Marilena C. D. V. Corrêa

    Full Text Available A medicalização é um fenômeno social difuso nas sociedades ocidentais que se expressa segundo um diferencial de gênero. A gravidez é um momento fortemente medicalizado, no qual as mulheres se vêem cercadas de uma rede de vigilância de seu corpo, sendo responsabilizadas não só pela própria saúde, mas também pela produção de um feto saudável. O controle dos riscos no pré-natal é proposto, entretanto, em um contexto no qual as possibilidades diagnósticas são amplamente majoritárias comparativamente às possibilidades terapêuticas. Essa defasagem é agravada pelo fato de, no Brasil, o abortamento ser ilegal. Este artigo é fruto de pesquisa empírica realizada em um ambulatório público de genética pré-natal, que constou de: observação das práticas de atendimento, revisão de prontuários e realização de entrevistas com profissionais de saúde. Discutem-se o contexto fortemente medicalizado do aconselhamento genético no Brasil e a percepção dos médicos sobre suas práticas neste contexto. É discutido também o possível impacto sobre a tomada de decisão das mulheres atendidas em relação a riscos, técnicas, exames e seus desdobramentos.

    2003-02-01

    We investigated post-natal development of the adrenocortical stress-response system in captive American kestrels (Falco sparverius) by measurements of baseline and stress-induced levels of corticosterone at ages 10, 16, 22, and 28 days post-hatching. Baseline levels of corticosterone increased significantly during post-natal development and although chicks aged 10- and 16-days old exhibited comparable baseline corticosterone levels, those of 22-day-old chicks were significantly higher and those of 28-day-old chicks close to fledging were higher than all younger groups. Chicks in this study exhibited low levels of stress-induced corticosterone early in development and did not exhibit adult-type stress-induced levels of corticosterone until 22 days of age post-hatching. Finally, although baseline and stress-induced levels of 28-day-old birds were significantly higher than one-year-old adults, there was no relationship between baseline corticosterone concentrations and time to nest departure. The fact that baseline levels of corticosterone are low during early development and then increase during later development may be an adaptation to the negative effects of chronically elevated corticosterone levels and as previously noted in other studies may minimize these negative effects on rapid growth and development in young birds, potentially maximizing normal growth. The ability of even young kestrel chicks to elevate corticosterone levels in response to stress suggests that they may be able to physiologically cope with food shortages associated with unpredictable food resources which wild kestrels often face.

    Full Text Available Background: Despite the development of context-specific guidelines, cryptococcal meningitis (CCM remains a leading cause of death amongst HIV-infected patients. Results from clinical audits in routine practice have shown critical gaps in clinicians’ adherence to recommendations regarding the management of CCM.Aim: The aim of this study was to review the acute management of CCM at an urban district hospital in KwaZulu-Natal, South Africa with a view to making recommendations for improving care.Setting: An urban district hospital in KwaZulu-Natal, South Africa.Methods: A retrospective audit was performed on clinical records of all patients (age > 13 years admitted to the hospital with a diagnosis of CCM between June 2011 and December 2012.Results: Measurement of cerebrospinal fluid opening pressure at initial lumbar puncture (LP was done rarely and only 23.4% of patients had therapeutic LPs. The majority of patients (117/127; 92.1% received amphotericin B, however, only 19 of the 117 patients (16.2% completed the 14-day treatment target. Amphotericin B-toxicity monitoring and prevention was suboptimal; however, in-patient referral for HIV counselling and testing was excellent.Conclusions: The quality of care of CCM based on selected process criteria showed gaps in routine care at the hospital despite the availability of context-specific guidelines. An action plan for improving care was developed based on stakeholders’ feedback. A repeat audit should be conducted in the future in order to evaluate the impact of this plan and to ensure that improvements are sustained.

    2017-01-01

    Full Text Available Introduction: Rural radiographers require, over and above traditional radiographic expertise, additional competencies which to a certain degree are unique however not limited to rural practice. Previous studies, however, have focused more attention primarily on other rural health professionals such as doctors and nurses leaving a research need in this field. This article focuses on the additional competencies that may be required for rural radiographers.Aim: To investigate and identify additional core competencies required by radiographers working in rural hospitals of KwaZulu-Natal in order to propose a continuous professional development strategy aimed at rural radiographers.Methods: An exploratory sequential design was utilised with qualitative (Phase I and quantitative (Phase II strands involving seven participants and 109 respondents, respectively. Only radiographers working in rural KwaZulu-Natal hospitals were included in the study. The four major themes and categories identified in Phase I were used to develop data collection instrument for Phase II of the study.Results: Collectively, the results revealed that there were a number of additional core competencies such as, but not limited to, teamwork, ability to do basic obstetric ultrasound scans, leadership, management and reporting on plain radiographs, all of which are required by rural radiographers. In 2014 when these competencies were checked against a single curriculum, it was found that majority of them were either partially covered or not at all covered.Conclusion: The study provides additional information on context specific core competencies and, therefore, may act as a catalyst to influence the future of radiographers working in rural areas of South Africa.

    2015-02-01

    Full Text Available Background: Compulsory community service (CCS for nurses commenced in South Africain January 2008 after it was legislated in the new Nursing Act (Act No. 33 of 2005. Nurses completing their registered nurse programme are registered as community nurse practitioners (CNPs during the CCS period and make up the largest number of health professionals serving CCS. Whilst health institutions have welcomed CNPs as additional resources for the shortage of nursing staff, no structured guidelines have been provided at a regional level as to how these nurses should be utilised or managed during the CCS year. To date, no large-scale study has been conducted on nurses carrying out CCS in order to generalise the findings.Objectives: To establish the perceptions of newly-qualified nurses carrying out CCS in KwaZulu-Natal, South Africa.Method: A quantitative survey design was used to obtain data from a randomly selected sample of the 2012 cohort of nurses carrying out CCS in KwaZulu-Natal.Results: CNPs have a positive attitude toward CCS and perceive themselves as being well prepared for the year of community service in terms of knowledge, skills and ability to administer nursing care. They identified positive benefits of the year of community service.The concerns raised were limited orientation and support; and a few CNPs experienced problems of acceptance by the nurses with whom they work.Conclusion: It is recommended that all health institutions who receive CNPs develop structured orientation and support for these nurses in order to promote their development, thereby enhancing their benefit to the communities they serve.

    Full Text Available Background: Due to the lack of exact data on natality and infant mortality rates of the Roma living in Slovakia we aim to look closer into these parameters, analyze them and in this respect compare two ethnic groups: Roma and non-Roma Slovak children. Material and methods: In the time period from 1997 to 2011, we collected data in selected parameters (birth rate, infant mortality rate, the number of newborns with low birth weight, the number of children abandoned by their mothers after birth in the Prešov region, and we evaluated them. Findings: A declining natality rate was observed in non-Roma children, as opposed to an upward trend in Roma children. In 1997, every fourth child was born to a Roma woman; in 2011, it was every third child. A declining infant mortality rate was observed in all groups studied. In the Roma children, the decline in the infant mortality rate was the biggest, yet the mere infant mortality rate, in this group of children, was the highest – in 1997 and in 2011 approximately 3-times higher than in the children born to non-Roma mothers. Conclusion: In our study, the infant mortality rate of Roma children is on decline, yet still it is high when compared to the non-Roma population. This may be caused by low interest of the Roma in providing health care to their children and their low responsibility or their inability to take responsibility for health and health care education of their children.

The Report cites KwaZulu-Natal in South Africa as being at the heart of the HIV/AIDS epidemic; this article is based on research on dating and sexuality among HIV-positive people in KwaZulu-Natal. Dating and sexuality are an integral part of living. Yet HIV-positive persons are denied intimacy at a time when this is most needed (Kasiram in Kasiram, Partab & Dano, 2006. Little is known about the full range of sexual adaptations that HIV-infected individuals choose (Schiltz & Sandfort, 2000. Kasiram, Partab, Dano and Van Greunen (2003:9 cite interaction and intimacy among HIV-positive persons as a neglected research focus, while Painter (2001 adds that insufficient attention is afforded to couple relationships for infected people. An important reason that motivated this study on dating and sexual challenges faced by HIV-positive people was the first author’s (the main researcher’s personal experience of being HIV positive and counselling and life coaching HIV-positive people. She is confronted regularly with variations of the question “Will I be normal?”, which often translates to: “Will I be able to date and have sex.

    Full Text Available All the newborns with umbilical venous catheters, hospitalized in the neonatal intensive care unit at Januário Cicco Maternity Hospital in Natal, Brazil, between January, 2003 and December, 2004 were studied. The prevalence of Candida species in the tips of intra-venous catheters was assessed, as well as the coexisting exposures that the patients were subjected to. Catheter tips were cultivated in blood agar and when yeast culture occurred, the colony was subcultivated for species identification through morphologic and biochemical assays. From a total of 240 catheters, 41 were positive for yeasts, and 34 were submitted to identification. The following agents were isolated: 13 C. albicans (38%, 10 Candida parapsilosis (29%, 8 C. tropicalis (20%, one C. guilliermondii (3%, one C. famata (3% and one Trichosporon spp. (3%. Three patients among those with positive catheter tip fungal cultures were also hemoculture positive, with the same fungal species at both sites. Among the coexisting exposures, it should be pointed out that all the patients underwent broad spectrum antibiotic therapy, used a nasogastric probe, in addition to undergoing other invasive procedures such as mechanical ventilation and umbilical catheter implantation.Foram estudados, entre janeiro de 2003 a dezembro de 2004, todos os recém-nascidos internados na UTI neonatal da Maternidade Escola Januário Cicco, portadores de cateter venoso umbilical. Avaliou-se a prevalência de espécies de Candida nas pontas de cateteres intra-venosos dos neonatos, e os fatores associados a que os pacientes estavam submetidos. As pontas de cateter foram cultivadas em ágar sangue, e, quando houve crescimento de colônia leveduriforme, esta foi subcultivada para a realização de provas morfológicas e bioquímicas para identificar a espécie. Do total de 240 cateteres analisados, 41 apresentaram crescimento de leveduras, sendo 34 encaminhados para identificação, observando-se os seguintes

    Full Text Available The growth and development play an important role in orthodontics mainly in bone, because it can determine the maturity of the bone. Bone maturity evaluation is very important in orthodontic treatment, because there are many individual variations in growth and development such as time, duration and velocity of the growth. Nutritional status during pregnancy and infant period will influence the growth and the development of bone. Protein diet is an important factor, which will determine the optimal calcification during bone growth and development stages. Bone calcification, in orthodontics, can be used to estimate the bone maturity for diagnosis and treatment planning. The purpose of this study was to recognize ones ability to surpass calcium and phosphor deficiency because of pre and postnatal protein deficiency. There were three groups of samples of Rattus norvegicus rats. The first group was the control group with standard diet, the second was the infant group with pre and postnatal protein deficiency, and the third group was young rat at weaning age with pre and postnatal protein deficiency supplemented with enough protein in the diet. Bone calcification stage was analyzed: 1 Histologically by measuring epiphyseal width on right femur; 2 by measuring calcium and phosphor concentration on left femur with Spectrophotometry Atomic Absorption and spectroscopy ultra light visible. The data were analyzed by one way ANOVA continued by t test. The result showed that: 1 there was significant (p < 0.01 epiphyseal width difference between group I and II, I and III (p < 0,01 but there was not significant difference between group II & III (p > 0.05; 2 there was significant calcium and phosphor concentration on bone between group I, II and III (p < 0.01. It was concluded that bone calcification damage because of pre and post natal protein deficiency was an irreversible process. Protein supplement after bone calcification could not restore the condition.

    Molecular studies in social mammals rarely compare the inferences gained from genetic analyses with field information, especially in the context of dispersal. In this study, we used genetic data to elucidate sex-specific dispersal dynamics in the Virunga Massif mountain gorilla population (Gorilla beringei beringei), a primate species characterized by routine male and female dispersal from stable mixed-sex social groups. Specifically, we conducted spatial genetic structure analyses for each sex and linked our genetically-based observations with some key demographic and behavioural data from this population. To investigate the spatial genetic structure of mountain gorillas, we analysed the genotypes of 193 mature individuals at 11 microsatellite loci by means of isolation-by-distance and spatial autocorrelation analyses. Although not all males and females disperse, female gorillas displayed an isolation-by-distance pattern among groups and a signal of dispersal at short distances from their natal group based on spatial autocorrelation analyses. In contrast, male genotypes were not correlated with spatial distance, thus suggesting a larger mean dispersal distance for males as compared to females. Both within sex and mixed-sex pairs were on average genetically more related within groups than among groups. Our study provides evidence for an intersexual difference in dispersal distance in the mountain gorilla. Overall, it stresses the importance of investigating spatial genetic structure patterns on a sex-specific basis to better understand the dispersal dynamics of the species under investigation. It is currently poorly understood why some male and female gorillas disperse while others remain in the natal group. Our results on average relatedness within and across groups confirm that groups often contain close relatives. While inbreeding avoidance may play a role in driving female dispersal, we note that more detailed dyadic genetic analyses are needed to shed light on

    Full Text Available Background: Although deep vein thrombosis (DVT is a preventable disease, it increases the morbidity and mortality in hospitalised, patients, resulting in considerable economic health impact. The identification and primary prevention of risk factors using risk assessment and stratification with subsequent anti-thrombotic prophylaxis in moderate- to severe-risk categories is the most rational means of reducing morbidity and mortality. Aim and setting: The aim of the study was to describe the profile and frequency of known risk factors or comorbidities of hospitalised medical patients with ultrasound-diagnosed DVT in an urban district hospital in KwaZulu-Natal. Methods: A retrospective review of clinical notes of all medical patients (age ≥ 13 years admitted to the hospital with ultrasound-diagnosed DVT between July and December 2013. Results: The median age was 40 years (interquartile range 32–60 years and female preponderance was 72.84%. HIV and tuberculosis emerged as the prevalent risk factors, accounting for 51.85% and 35.80%, respectively. Other risk factors observed were recent hospitalisation (34.57%, smoking (25.93%, previous DVT (19.75% and congestive cardiac failure (18.52%. Conclusion: DVT in our study occurred predominantly in young female patients unlike previous studies where patients were generally older. Furthermore, HIV and tuberculosis were the two most common known risk factors or comorbidities observed. Clinicians should have a heightened awareness of venous thromboembolism in patients with either condition or where both conditions occur together and appropriate thromboprophylaxis should be administered.

    Full Text Available Youth unemployment is a problem that requires different diagnoses from different stakeholders, and informal business is important for local economic development. However, the youth are not much involved in the informal sector. Youth involvement in the informal sector will help address youth unemployment. This article aims to evaluate the impact of informal business development on reducing youth unemployment in the eThekwini Municipality, KwaZulu-Natal Province, South Africa. Through in-depth interviews with eThekwini Municipality officials, business support organisations and unemployed youth, assessment of supporting documents and site visits, enough data were collected to support the notion that informal business development can work to address unemployment in the municipality. The findings showed that the informal economy does not have a significant impact on completely mitigating the unemployment problem in the municipality. However, the sector is very important for economic growth and development, as well as job creation, which will begin to alleviate the unemployment problem. Thus both the formal and informal sectors of the economy need to be examined as potentially providing the first steps to achieving the long-term employment goals for the eThekwini Municipality.

    The purpose of this study was to describe the characteristics of a random sample of prison inmates from two provinces in South Africa with respect to correct knowledge regarding HIV/AIDS and sexual transmitted infection (STI) risk and beliefs about condom use. This cross-sectional descriptive study of 357 prison inmates formed part of a larger longitudinal investigation designed to implement a health education intervention for prison inmates in the KwaZulu-Natal (KZN) and Mpumalanga (MP) provinces of South Africa. Mean differences for groups were compared across sites using Analysis of Variance (ANOVA). Inmates from KZN were less likely to agree that 'It is important to use condoms every time you have sex' F (1355) = 25.8, pCondoms work well to prevent the spread of HIV' F (1355) = 11.7, pCondoms also prevent pregnancy' F (1355) = 5.1, pcondom use behaviour suggested that future prevention efforts focus on the importance of using condoms to prevent the spread of HIV/AIDS and other STIs.

Métodos: Estudo transversal com análise descritiva dos dados da PNS 2013, coletados no DATASUS entre dezembro de 2016 e janeiro de 2017. Responderam à pesquisa mulheres de 18 a 49 anos de idade que tiveram algum parto entre 01/01/2012 a 27/07/2013. A cobertura do pré-natal foi definida pela proporção de mulheres que responderam positivamente ao questionamento: “Na última vez que a senhora esteve grávida, a senhora fez pré-natal?”. Os dados coletados foram: assistência pré-natal, idade, cor da pele, grau de instrução, aconselhamentos, recebimento do cartão pré-natal, consultas realizadas, assistência ao parto por região ou unidade da federação. Resultados: Houve elevada cobertura do acompanhamento pré-natal (97,4% IC95% 96,5-98,4, com entrega do cartão pré-natal (95,3% IC95% 93,6-97,0 e início de pré-natal com menos de 13 semanas de gestação (83,7% IC95% 80,7-86,6, porém baixa proporção de gestantes com todos os aconselhamentos (69,2% IC95% 65,5-72,9 e com exames para Sífilis (64,8% IC95% 61,0-68,7. Entre as que realizaram o pré-natal, 69,33% das gestantes indicaram que todas as consultas foram feitas através do Sistema Único de Saúde. As regiões Norte e Nordeste apresentaram maior proporção de partos vaginais, porém menor número de consultas de pré-natal por gestante. Conclusão: Apesar de elevada cobertura da assistência pré-natal no Brasil, os indicadores mostram que ainda há inadequações no acesso ao serviço.

    Full Text Available O diagnóstico pré-natal está indicado para algumas genodermatoses graves, como a epidermólise bolhosa distrófica recessiva e a epidermólise bolhosa juncional. A biópsia de pele fetal foi introduzida em 1980, mas não pode ser realizada antes da 15a semana de gestação. A análise do DNA fetal é método preciso e pode ser realizado mais precocemente na gestação. No entanto, deve-se conhecer a base molecular da genodermatose, e é essencial determinar a mutação e/ou marcadores informativos nas famílias com criança previamente afetada. O DNA fetal pode ser obtido pela biópsia da vilosidade coriônica ou amniocentese. O diagnóstico genético pré-implantação tem surgido como alternativa que dispensa a interrupção da gestação. Essa técnica, que envolve fertilização in vitro e teste genético do embrião. vem sendo realizada para genodermatoses em poucos centros de referência. A ultra-sonografia é exame não invasivo, mas tem uso limitado no diagnóstico pré-natal de genodermatoses. A ultrasonografia tridimensional geralmente estabelece o diagnóstico tardiamente na gestação, e há apenas relatos anedóticos de diagnóstico pré-natal de genodermatoses usando esse método.Prenatal diagnostic testing is indicated for some severe genodermatoses, such as recessive dystrophic epidermolysis bullosa and junctional epidermolysis bullosa. Fetal skin biopsy was introduced in 1980, but it cannot be performed before 15th gestational week. Fetal DNA analysis is a precise method and can be performed earlier in pregnancy. However, the molecular basis of the genodermatoses must be known and it is essential to determine the gene mutations and/or informative markers in the families with a previously affected child. Fetal DNA can be obtained by chorionic villus sampling or amniocentesis. Preimplantation genetic diagnosis is an alternative approach obviating the need for termination of pregnancy.

    Rapid HIV tests have improved access to HIV diagnosis and treatment by providing quick and convenient testing in rural clinics and resource-limited settings. In this study, we evaluated the quality management system for voluntary and provider-initiated point-of-care HIV testing in primary healthcare (PHC) clinics in rural KwaZulu-Natal (KZN), South Africa. We conducted a quality assessment audit in eleven PHC clinics that offer voluntary HIV testing and counselling in rural KZN, South Africa from August 2015 to October 2016. All the participating clinics were purposively selected from the province-wide survey of diagnostic services. We completed an on-site monitoring checklist, adopted from the WHO guidelines for assuring accuracy and reliability of HIV rapid tests, to assess the quality management system for HIV rapid testing at each clinic. To determine clinic's compliance to WHO quality standards for HIV rapid testing the following quality measure was used, a 3-point scale (high, moderate and poor). A high score was defined as a percentage rating of 90 to 100%, moderate was defined as a percentage rating of 70 to 90%, and poor was defined as a percentage rating of less than 70%. Clinic audit scores were summarized and compared. We employed Pearson pair wise correlation coefficient to determine correlations between clinics audit scores and clinic and clinics characteristics. Linear regression model was computed to estimate statistical significance of the correlates. Correlations were reported as significant at p ≤0.05. Nine out of 11 audited rural PHC clinics are located outside 20Km of the nearest town and hospital. Majority (18.2%) of the audited rural PHC clinics reported that HIV rapid test was performed by HIV lay counsellors. Overall, ten clinics were rated moderate, in terms of their compliance to the stipulated WHO guidelines. Audit results showed that rural PHC clinics' average rating score for compliance to the WHO guidelines ranged between 64.4% (CI

    It is relatively easy to identify the reservoir from which a given comet was ejected. But dynamical models demonstrate that the main cometary reservoirs (Kuiper Belt, Oort Cloud) each contain icy bodies that formed in a range of environments in the protoplanetary disk, and the Oort Cloud may even contain bodies that formed in disks of sibling stars in the Sun s birth cluster. The cometary nucleus contains clues to the formative region(s) of its individual components. The composition of ices and rocky grains reflect a range of processes experienced by material while on the journey from the natal interstellar cloud core to the cometary nucleus. For that reason, emphasis is placed on classifying comets according to their native ices and dust (rather than orbital dynamics). Mumma & Charnley [1] reviewed the current status of taxonomies for comets and relation to their natal heritage.

  1. The evolution of female sex pheromones

    2013-08-01

    Full Text Available The role of female sex pheromones in natural selection, particularly as a means for species recognition to avoid the generation of hybrid offspring with low fitness, has been widely explored and is generally accepted by scholars. However, the significance of sex pheromones in shaping mate choice (sexual selection and in competition over breeding resources (social selection has been largely ignored. The effect of sexual selection on sex pheromones as a sexually dimorphic signaling trait has been discounted because the amount of pheromone released by females is typically minute, while the role of sex pheromones in competition over breeding resources (other than mates has not yet been considered. As a result of natural selection, variation in sex pheromones among females is expected to be low, and males are not expected to choose their mates among pheromone-releasing conspecific females. Sexual selection, on the other hand, should drive the increase in pheromone variance among females, and males are expected to choose females based on this variation. Moreover, social selection resulting from more general social interactions, for example competition among females for breeding sites and food, should also promote variance among female sex pheromones. Here, we review the current evidence for each of the three selection processes acting on sex pheromones of female moths as an advertising trait. We suggest that the three selection types are not mutually exclusive but rather act together to promote different fitness components in diverse ecological situations [Current Zoology 59 (4: 569–578, 2013].

    Full Text Available A study was conducted on 22,158 special B prescriptions (notificações B containing amphetamine-type anorectic drugs or benzodiazepines, obtained from compounding pharmacies or drugstores located in the city of Natal, RN, Brazil. The data obtained were compared with those from other Brazilian cities. Results showed that compounding pharmacies dispensed 85.4% of the prescriptions, indicating that these pharmacies filled out nearly 10 times more of these prescriptions than did the drugstores. The majority (83.5% of B prescriptions issued for the compounding pharmacies were for women, where the female/male patient ratio ranged from 7.1/1.0 for mazindol to 10.3/1.0 for amfepramone. Similar results were obtained for the benzodiazepines with ratios of 1.9/1.0 for clonazepam to 15.6/1.0 for oxazepam. Omissions and mistakes were present in the B prescriptions, including missing information about the patient (in 49.6% of the documents or about the pharmacies or drugstores (50.4%. There were cases where the name and/or CRM of the physician was lacking. It was noted that one medical doctor made out 1855 B prescriptions within one year. The same patient's name appeared on 138 prescriptions, and the same RG (identification card number was present in 125 others.

    Full Text Available A growing body of evidence shows within-population variation in natal dispersal, but the effects of such variation on social relationships and the kin composition of groups remain poorly understood. We investigate the link between dispersal, the kin composition of groups, and proximity patterns in a population of black-and-white colobus (Colobus vellerosus that shows variation in female dispersal. From 2006 to 2011, we collected behavioral data, demographic data, and fecal samples of 77 males and 92 females residing in eight groups at Boabeng-Fiema, Ghana. A combination of demographic data and a genetic network analysis showed that although philopatry was female-biased, only about half of the females resided in their natal groups. Only one group contained female-female dyads with higher average relatedness than randomly drawn animals of both sexes from the same group. Despite between-group variation in female dispersal and kin composition, female-female dyads in most of the study groups had higher proximity scores than randomly drawn dyads from the same group. We conclude that groups fall along a continuum from female dispersed, not kin-based, and not bonded to female philopatric, kin-based, and bonded. We found only partial support for the predicted link between dispersal, kin composition, and social relationships. In contrast to most mammals where the kin composition of groups is a good predictor of the quality of female-female relationships, this study provides further support for the notion that kinship is not necessary for the development and maintenance of social bonds in some gregarious species.

    Acute, short-term effects of early-life stress and associated glucocorticoid upregulation on physiology and survival are widely documented across vertebrates. However, the persistence and severity of these effects are largely unknown, especially through the adult stage and for natural systems. Here, we investigate physiological, morphological, and survival effects of post-natal glucocorticoid upregulation across the nestling, juvenile, and adult life stages in house sparrows (Passer domesticus). We manipulate circulating corticosterone concentration in wild, free-living house sparrow nestlings and monitor body size, size-corrected mass, two measures of health (hematocrit and phytohemagglutinin-induced skin swelling), and survival in a captive environment until adulthood. We find that early-life corticosterone exposure depresses nestling size-corrected mass in both sexes, with no strong effect of the treatment on body size or our two measures of health. Birds are able to compensate for negative effects of high early-life corticosterone exposure in the long-term and this effect largely disappears by the juvenile and adult stages. However, treatment has a negative effect on survival through one year of age, suggesting that long-term compensation comes at a price. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available This study explores how the media frame disaster contingency plans which include preparedness, mitigation, response and recovery of the KwaZulu-Natal province before, during and in the aftermath of natural disasters. The province has been stricken by natural disasters. Although newspapers report the disasters they fail to give details of disaster contingency plans that should be available to those who are susceptible to, and the victims of disasters. Based on a content analysis of 114 online newspaper articles between 2000 and 2013 to examine how the media framed the KZN government’s disaster contingency plans. This study concludes that the highest occurrence of disasters (71% was from 2011 onwards as compared to previous years, and most of these were associated with areas that are susceptible to floods (34%. The findings of the study highlight that the media placed an emphasis on disaster response (41% over preparedness (24% and mitigation (7%. The outcomes suggest that newspaper organisations need to appoint a designated reporter responsible for disaster management issues. This is relevant because this study conveys findings that have the potential to persuade government and newspaper organisations to collaborate and to ensure that their officials are multi-skilled and able to cover all phases of disaster management in their articles, in order for these to be understood at all levels of society. This study further adds to the growing body of knowledge regarding quality journalism that meets its objectives.

    Full Text Available The notion of teacher leadership is implicit in official documentation in the South African education system post 1994, which emphasises a move towards a more shared and participatory approach to the practice of leadership and management in schools. The concept of teacher leadership is embedded in a distributed leadership theoretical framing which emphasises that leadership need not be located only in the position of the principal but can be stretched over a range of people who work at different levels in a school. We report on a study in which the perceptions of teachers' on their understanding and experiences of teacher leadership were explored. The study adopted a survey approach and utilised closed questionnaires to gather data from 1,055 post level-one teachers across a range of schools of diverse contexts in KwaZulu-Natal. We found that while teachers supported the notion of shared leadership and believed they were equipped to lead, their leadership was largely restricted to their classrooms. There was some evidence of teacher leadership amongst teacher colleagues in certain curricular and extra-curricular activities. However, teacher leadership in relation to school-wide and community issues was almost non-existent. We signal two problematics regarding the leadership of school teachers and consider the implication of these for the distribution of leadership, and therefore change, in schools.

    Full text: Effect of Protein-calorie malnutrition was studied on the pups born to mothers receiving either irradiated normal diet (consisted equal parts of gram and wheat) or irradiation low protein diet (consisted one part of normal diet and three parts of heat). Level of DNA, RNA and protein content were found markedly reduced in the brain of irradiated low protein diet fed pups than in the pups fed on the irradiated normal diet. Glucose 6-phosphate dehydrogenase activity was found lower while catalase and lipid peroxidation activity were higher in the pups given irradiated low protein diet, compared whit the pups fed irradiated normal diet. On the whole both the irradiated low protein diet as well as irradiated normal diet fed pups showed higher index of biochemical changes than in the unirradiated low protein diet fed pups. Post-natal mortality was 60% in the pups given irradiated low protein diet, whereas the pups fed on the irradiated normal diet and unirradiated low protein diet did not show any death. The study given evidence that feeding of the irradiated low protein diet interferes more with the development of brain compared with the pups fed on irradiated normal diet

    Cocaine use by pregnant women has increased dramatically in recent years. To assess the effect of maternal cocaine use on infant outcome, we enrolled 224 women (105 cocaine users, 119 control subjects) and their infants (all of 34 weeks or more gestational age and nonasphyxiated) in a prospective, blinded study. Results showed that infants exposed to cocaine were more likely to be admitted to the newborn intensive care unit, be treated for congenital syphilis, have a greater length of stay, and be discharged to a person other than the mother (all p 0.80). Infants of cocaine-using mothers and control subjects had a similar incidence of abnormal cranial and renal ultrasonographic findings and abnormal pneumocardiograms (all p > or = 0.32). We conclude that in this cohort of nonasphyxiated infants of 34 weeks or more gestational age, infants exposed to cocaine had more medical and social problems than control infants but did not differ statistically in the incidence of severe growth retardation, abnormal cranial or renal ultrasonographic findings, or abnormal pneumocardiograms. We suggest that natal interventions for the nonasphyxiated term and near-term infant exposed to cocaine should include a careful history and physical examination, follow-up plans, and social service involvement.

    The chemical composition of three edible seaweeds (Codium capitatum, Hypnea spicifera and Sargassum elegans) and two inedible seaweeds (Halimeda cuneata and Spyridia hypnoides) from the Indian Ocean along the KwaZulu-Natal East Coast, South Africa were investigated as a function of seasonal variation. The proximate compositions of the edible seaweeds were determined. In edible seaweeds, the moisture level ranged from 85.4 to 89.5%, protein from 6.1 to 11.8%, lipids from 7.5 to 13.1% and carbohydrates from 37.8 to 71.9%. Elemental concentrations in the five studied seaweeds varied significantly with season (P seaweeds which was dissimilar to that in inedible seaweeds. This study suggests that edible macro alga, C. capitatum and H. spicifera, could be potential sources of most essential nutrients and may contribute positively to the diet without posing the risk of adverse health effects due to low concentrations of toxic elements. However, due to high levels of As in S. elegans, its consumption should be moderated to reduce dietary exposure to this toxic element.

    Homosexual patients are affected by social factors in their environment, and as a result may not have easy access to existing health care services. Prejudice against homosexuality and homosexual patients remains a barrier to them seeking appropriate healthcare. The concern is that lesbians and gays might delay or avoid seeking health care when they need it because of past discrimination or perceived homophobia within the health care thereby putting their health at risk. The aim of the study was to explore and describe the experiences of homosexual patients utilising primary health care (PHC) services in Umlazi in the province ofKwaZulu-Natal (KZN). A qualitative, exploratory, descriptive study was conducted which was contextual innature. Semi-structured interviews were conducted with 12 participants. The findings of this study were analysed using content analysis. Two major themes emerged from the data analysis, namely, prejudice against homosexual patients by health care providers and other patients at the primary health care facilities, and, homophobic behaviour from primary health care personnel. Participants experienced prejudice and homophobic behaviour in the course of utilising PHC clinics in Umlazi, which created a barrier to their utilisation of health services located there. Nursing education institutions, in collaboration with the National Department of Health, should introduce homosexuality and anti-homophobia education programmes during the pre-service and in-service education period. Such programmes will help to familiarise health care providers with the health care needs of homosexual patients and may decrease homophobic attitudes.

    2016-10-01

    Full Text Available This study, done in KwaZulu-Natal, South Africa, sheds light into the challenges facing women entrepreneurs involved in tourism businesses and the opportunities they can harness in the tourism industry, with particular reference to some gender nuances. The study collected qualitative and quantitative data from respondents, and the data were analysed using content and descriptive analyses respectively. The challenges facing these women entrepreneurs, identified by this study, include lack of financial capital, low business capability, problem of size and scope, racial issues and traditional perceptions, and imperfect business location. Some opportunities for growth identified are local municipality support, internet marketing, and formation of business network for self-support and training. This study recommends business skills training for the women entrepreneurs in the areas of sourcing business funding, creating unique value proposition, product excellence, marketing capability, operational excellence and customer service. Although this study was conducted in a South African province, it has implications for women entrepreneurs in sub-Saharan Africa, and beyond.

  14. Challenging cheap-labour theory: Natal and Transvaal coal miners, ca 1890-1950

    In the first half of the twentieth century, South Africa's two main coal-producing provinces, Natal and the Transvaal, were regarded as having separate industries. Comparing the two, the article shows that their geology, markets, ownership and organization were distinctive. In contrast, the patterns of labour struggles were alike, reflecting labour processes, racial divisions, and legal and ideological frameworks that were similar. The historiography of South African mining labour has emphasized the role of black migrants, who 'oscillated' between the mines and the rural areas from where they originated and to which they retired. While structuralist analyses argued that migrancy was the bedrock of a cheap-labour system that underpinned white power, leading social historians stressed that migrants were primarily rural men. The account presented here rejects the thrust of both positions, showing that a high proportion of coal miners settled around the mines. More of them would have done so had this been permitted, and the same applies to Africans working on the gold mines. Given that cheap-labour theory strengthens the exceptionalism that runs through much South African history, rejecting it can open up new possibilities for comparative study. In passing, the article reveals that black workers participated in the militant 1913 strike by the Witwatersrand's white mine workers.

    Full Text Available Ten out of fifty fresh and refrigerated samples of shrimp (Litopenaeus vannamei collected from retailers in Natal (Rio Grande do Norte, Northeastern Brazil tested positive for Vibrio parahaemolyticus. The Kanagawa test and multiplex PCR assays were used to detect TDH and TRH hemolysins and the tdh, trh and tlh genes, respectively. All strains were Kanagawa-negative and tlh-positive. Antibiotic susceptibility testing was done for seven antibiotics by the agar diffusion technique. Five strains (50% presented multiple antibiotic resistance to ampicillin (90% and amikacin (60%, while two strains (20% displayed intermediate-level resistance to amikacin. All strains were sensitive to chloramphenicol. Intermediate-level susceptibility and/or resistance to other antibiotics ranged from 10 to 90%, with emphasis on the observed growing intermediate-level resistance to ciprofloxacin. Half our isolates yielded a multiple antibiotic resistance index above 0.2 (range: 0.14-0.29, indicating a considerable risk of propagation of antibiotic resistance throughout the food chain.

    To determine the prevalence of repeat teenage pregnancy and the interval between first/most recent and repeat pregnancies, as well as to evaluate the sexual/reproductive health characteristics of teenagers with repeat pregnancies. A prospective observational study was undertaken at a hospital in KwaZulu-Natal, South Africa, between May and September 2013. Teenagers aged 13-19years who were pregnant, had recently delivered, or had terminated a pregnancy were enrolled. A questionnaire was used to obtain data. Among 341 participants, 281 (82.4%) were seen for a first pregnancy and 60 (17.6%) for a repeat pregnancy. The interval between first/most recent and repeat pregnancies was 24months or lower in 45 (75.0%) of repeat pregnancy participants. Only 58 (17.0%) participants had previously used contraception (54 [93.1%] of whom stopped within 12months) and 28 (8.2%) had used emergency contraception. More participants with repeat pregnancy than with first pregnancy had a positive HIV status (18 [30.0%] vs 26 [9.3%]; Pteenagers in South Africa is worrying. Focused interventions targeting teenagers following their first pregnancy need to be urgently implemented. Copyright © 2016 International Federation of Gynecology and Obstetrics.

    Rabies remains a significant problem throughout much of the developing world. An estimated 69 000 people die annually from exposure to rabies. Most of these deaths are the result of being bitten by a rabid dog. Mass vaccination campaigns targeting dogs have been implemented around the world in an attempt to control or eliminate canine rabies. We analysed the vaccination and cost data for a campaign in the KwaZulu-Natal province of South Africa; we found that the cost per dog vaccinated to be $6.61 for mass campaigns and $5.41 for local campaigns. We also estimated the cost of human post-exposure prophylaxis (PEP). The cost of PEP is approximately $64.50 on average per patient, and $333 on average for the 9% of patients who receive RIG. We also found that the districts that vaccinated the most dogs per capita experienced the highest rates of human treatment and thus had the highest PEP costs. © 2014 Blackwell Verlag GmbH.

    Full Text Available The research took into account accepted standards of good policy formulation to provide perspective and contextualise the study, and delineated educational challenges for the sector.The following theoretical frameworks guided the study: a constructivist approach in interpreting and  evaluating the role of school libraries within an education system based in constructivist principles, the traditional policy model to evaluate policy formulation and design, and a social constructionist view of policy in the interpreting of policy development and implementation. The epistemological basis for the main   methodology, the Delphi technique, was social constructivism.The research design comprised two phases.  Qualitative data collected from the Delphi panel's expert opinion was interpreted to analyse the policy document critically and assess its implementation strategy.  Quantitative data from an analysis of existing surveys and reports provided an overview of the current state of school  library provisioning in KwaZulu-Natal.  School library models already being implemented in the province were evaluated against this background.The research results provide guidelines for reviewing and refining the provincial policy intervention and  brought to the fore several issues that need to be resolved to facilitate school library development in South Africa.

    Full Text Available Academic members of staff at the University of KwaZulu-Natal (UKZN are expected to publish in research journals that have been accredited by the South African based Department of Higher Education and Training. However, some members of staff have chosen to focus solely on the teaching aspect of their careers and as a result they have no publication record. In this study, a set of per annum productivity unit counts was calculated for every academic at UKZN. Because it is possible for a publishing academic to also record a zero count for a given year, it is necessary to develop an appropriate methodology that can distinguish this zero count from one that will always be recorded by a non-publishing academic. By fitting a zero-inflated Poisson model to the data, specific factors can be identified that separately drive the non-publishing and publishing processes at UKZN. In particular, having a PhD and working in a large school has a significant impact on improving the research output of a publishing academic. If UKZN wants to become a research-focused university, non-publishing academics should be encouraged to undertake a PhD degree.

    Full Text Available Abstract Background South Africa, with its scientific capacity, good infrastructure and high HIV incidence rates, is ideally positioned to conduct large-scale HIV prevention trials. The HIV Prevention Research Unit of the South African Medical Research Council conducted four phase III and one phase IIb trials of women-initiated HIV prevention options in KwaZulu-Natal between 2003 and 2009. A total of 7046 women participated, with HIV prevalence between 25% and 45% and HIV incidence ranging from 4.5-9.1% per year. Unfortunately none of the interventions tested had any impact on reducing the risk of HIV acquisition; however, extremely valuable experience was gained, lessons learned and capacity built, while the communities gained associated benefits. Experience Our experience in conducting these trials ranged from setting up community partnerships to developing clinical research sites and dissemination of trial results. Community engagement included setting up community-based research sites with approval from both political and traditional leaders, and developing community advisory groups to assist with the research process. Community-wide education on HIV/sexually transmitted infection prevention, treatment and care was provided to over 90 000 individuals. Myths and misconceptions were addressed through methods such as anonymous suggestion boxes in clinic waiting areas and intensive education and counselling. Attempts were made to involve male partners to foster support and facilitate recruitment of women. Peer educator programmes were initiated to provide ongoing education and also to facilitate recruitment of women to the trials. Recruitment strategies such as door-to-door recruitment and community group meetings were initiated. Over 90% of women enrolled were retained. Community benefits from the trial included education on HIV prevention, treatment and care and provision of ancillary care (such as Pap smears, reproductive health care and

    Full Text Available KwaZulu-Natal province, South Africa, has among the highest burden of XDR TB worldwide with the majority of cases occurring due to transmission. Poor access to health facilities can be a barrier to timely diagnosis and treatment of TB, which can contribute to ongoing transmission. We sought to determine the geographic distribution of XDR TB patients and proximity to health facilities in KwaZulu-Natal.We recruited adults and children with XDR TB diagnosed in KwaZulu-Natal. We calculated distance and time from participants' home to the closest hospital or clinic, as well as to the actual facility that diagnosed XDR TB, using tools within ArcGIS Network analyst. Speed of travel was assigned to road classes based on Department of Transport regulations. Results were compared to guidelines for the provision of social facilities in South Africa: 5km to a clinic and 30km to a hospital.During 2011-2014, 1027 new XDR TB cases were diagnosed throughout all 11 districts of KwaZulu-Natal, of whom 404 (39% were enrolled and had geospatial data collected. Participants would have had to travel a mean distance of 2.9 km (CI 95%: 1.8-4.1 to the nearest clinic and 17.6 km (CI 95%: 11.4-23.8 to the nearest hospital. Actual distances that participants travelled to the health facility that diagnosed XDR TB ranged from 50 km (n = 109, 27%, with a mean of 69 km. The majority (77% of participants travelled farther than the recommended distance to a clinic (5 km and 39% travelled farther than the recommended distance to a hospital (30 km. Nearly half (46% of participants were diagnosed at a health facility in eThekwini district, of whom, 36% resided outside the Durban metropolitan area.XDR TB cases are widely distributed throughout KwaZulu-Natal province with a denser focus in eThekwini district. Patients travelled long distances to the health facility where they were diagnosed with XDR TB, suggesting a potential role for migration or transportation in the XDR TB

  4. Reproductive status and testosterone among females in cooperative mole-rat societies.

    2013-06-15

    Sexual selection acts on traits that increase reproductive success. Variation in reproductive success is often higher among males than females. Consequently, sexual selection has been studied extensively in males while its possible role in females has only recently attracted considerable attention. In some cooperatively breeding species females compete intensely for reproductive opportunities and may thereby have evolved 'male-like' traits such as increased intra-sexual aggression and exaggerated secondary sexual traits. The expression of the latter tends to be testosterone-dependent in male vertebrates but whether this is also the case among females remains poorly understood. Here, we compare two cooperatively breeding mole-rat species (Natal, Cryptomys hottentotus natalensis, and Damaraland mole-rats, Fukomys damarensis) in which a single female monopolises reproduction through behavioural and physiological suppression, respectively, to evaluate the effect of female intra-sexual competition. Consistent with the hypothesis that intra-sexual competition has shaped patterns of testosterone (T) secretion among females in these species, we show that (i) female T levels in both species are significantly higher among breeding (BFs) (who may face the highest degree of intra-sexual competition) compared to non-breeding females (NBFs), (ii) that T levels in both species are significantly higher when access to unrelated males can be assumed to be greatest (i.e., wet season), and (iii) that the average female T levels are a full order of magnitude higher in the absence of a physiological mechanism of reproductive suppression. Together, our results suggest a role for intra-sexual competition in shaping patterns of T secretion among females of the social mole-rats and raise the possibility of a modulatory role for the mode of reproductive suppression on competition-related traits in females.

  5. Uncoupling direct and indirect components of female choice in the wild

    2002-01-01

    One of the most controversial debates in evolutionary biology concerns the fitness consequences of female choice in nature. Discriminating females may benefit from high-quality territories and/or sires with high-quality genes. Here we experimentally dissociate female preferences for high-quality territories and male body size in a wild population of side-blotched lizards, Uta stansburiana. Females preferred experimentally improved territories but still chose high-quality sires for their progeny. High-quality territories were associated with earlier egg-laying dates and larger eggs. These maternal effects, evidently stimulated by high-quality territories, have been shown to enhance competitive ability and therefore the likelihood that philopatric offspring will capitalize on the direct benefits of superior territories, previously shown to promote progeny growth rate and survival (most offspring do not disperse from their natal area). Paternity analysis within clutches co-sired by two males revealed that female preferences for large males were also adaptive in terms of indirect benefits. Females used sperm from large sires to produce sons and sperm from small sires to produce daughters. Differential allocation of resources and progeny sex was adaptive and demonstrates a high degree of female control in the mating system. PMID:12417752

    Analysis of 283 offspring born at the Duke University Primate Center show that young female ruffed lemurs, Varecia variegata, produce significantly more daughters, whereas old mothers produce more sons than expected. Data are compared to 3 hypotheses for sex ratio bias: the Trivers-Willard hypothesis which predicts that dominant females produce more males, the local resource competition (LRC) hypothesis which predicts that subordinate females produce more males, and the local resource enhancement (LRE) extension of the LRC hypothesis that females produce the sex that provides later cooperative benefits. In the case of Varecia, this may include alloparenting or cooperative breeding. The results are more consistent with the LRC model. However, observations of 8 mother-daughter relationships show that female dominance rank in free-ranging Varecia groups is age reversed, with daughters aggressively outranking their mothers. Daughters born into the group were not beneficial as future supporters in within-group intermatriline competition as assumed by the LRE model, or as subordinate alloparents, cooperative breeders or aids in territorial defense. Both sex ratio and ranking observations are consistent, however, with the hypothesis that mothers produce daughters when they are young and able to invade elsewhere and sons as they age and are less able to do so. This is supported by a single observation of a mother dispersing which resulted in her daughter inheriting the natal territory. These data are supportive of the LRE model with female alliances and cooperative breeding among dispersed females. Copyright (c) 2009 S. Karger AG, Basel.

    Full Text Available Background: Male circumcision is currently being promoted in South Africa as a HumanImmunodeficiency Virus (HIV prevention method. Effective implementation requires thathealthcare providers should believe in the procedure’s efficacy and should possess a positiveattitude. A study was undertaken amongst pharmacy and nursing students with differentobjectives.Objectives: To ascertain students’ knowledge, attitudes and perceptions regarding malecircumcision and (HIV prevention.Method: A descriptive cross-sectional study using anonymous questionnaires was undertakenamongst 4th year pharmacy and nursing students studying at a university in KwaZulu-Natal,after obtaining their consent. Data were captured and analysed using SPSS version 15.Results: A response rate of 83.18% and a mean knowledge score of 66.43% with relativelypositive attitudes (62.7 were obtained; 85.4% of the respondents felt that promoting malecircumcision is appropriate, with all Muslim students (n < 11 supporting the promotion ofmale circumcision. Even though all Muslim students supported male circumcision, only 3students were willing to perform the procedure if adequately trained (p < 0.03. The majorityof the female students were unwilling to perform the procedure (p < 0.005. A third of therespondents indicated that male circumcision would both undermine existing protectivebehaviours and strategies as well as increase riskier sexual behaviour. Over 54% of therespondents believed that the South African Health System would be able to cope with themassive male circumcision drive. The majority of the respondents favoured the procedure tobe done at birth. Pain was cited as the most important reason for not wanting to be circumcised.Conclusion: Pharmacy and nursing students have a moderate knowledge of male circumcisionand HIV prevention with relatively positive attitudes. The majority felt that promoting malecircumcision is appropriate and should be encouraged.

  11. Female sexual dysfunction in female genital mutilation.

    2016-01-01

    Female genital mutilation (FGM), otherwise known as female genital cutting (FGC), is currently very topical and has become a significant global political issue. The impact of FGM on the lives of women and girls is enormous, as it often affects both their psychology and physical being. Among the complications that are often under-reported and not always acknowledged is female sexual dysfunction (FSD). FSD presents with a complex of symptoms including lack of libido, arousability and orgasm. This often occurs in tandem with chronic urogenital pain and anatomical disruption due to perineal scarring.To treat FSD in FGM each woman needs specifically directed holistic care, geared to her individual case. This may include psychological support, physiotherapy and, on occasion, reconstructive surgery. In many cases the situation is complicated by symptoms of chronic pelvic pain, which can make treatment increasingly difficult as this issue needs a defined multidisciplinary approach for its effective management in its own right. The problems suffered by women with FGM are wholly preventable, as the practice need not happen. The current global momentum to address the social, cultural, economic and medical issues of FGM is being supported by communities, governments, non-governmental agencies (NGOs) and healthcare providers. It is only by working together that the practice can be abolished and women and girls may be free from this practice and its associated consequences. © The Author(s) 2016.

  12. The labour market for histopathologists in KwaZulu- Natal: Emerging issues

    Full Text Available The aim of this article was to assess the factors that shape the labour market for histopathologists in KwaZulu-Natal (KZN, South Africa. The literature on the labour market and labour processes of histopathologists is dominated by North American and European literature. This gap is most acutely felt on the African continent. This article attempts to fill this gap by shifting the focus towards understanding the factors that shape the professional milieu and labour market for histopathologists in South Africa. This study through a qualitative, descriptive and contextual design engaged in in-depth interviews with 70% of the population of histopathologists in KZN. The interviews were analysed thematically. These interviews were triangulated against labour market statistics for histopathologists in South Africa as well as a range of documentary evidence. The outcome of the study has demonstrated four key challenges facing the labour market for histopathologists: racial inequities persist in the labour market, gender inequities also persist, there is unfettered public-private sector mobility, and poor curriculum design at medical school level accounts for a limited input of registrars into the profession. The article concludes that there needs to be a shift from only studying the labour market and work organisation of clinical doctors to empirical research on the role of medical laboratory specialists in the healthcare chain, which will render South African histopathologists and their work visible. A set of labour market interventions is also suggested. Die artikel bestudeer die faktore wat die arbeidsmark vir histopatoloë in KwaZulu-Natal (KZN, Suid-Afrika beïnvloed.

    Full Text Available Background: Homosexual patients are affected by social factors in their environment, and as a result may not have easy access to existing health care services. Prejudice against homosexuality and homosexual patients remains a barrier to them seeking appropriate healthcare. The concern is that lesbians and gays might delay or avoid seeking health care when they need it because of past discrimination or perceived homophobia within the health care thereby putting their health at risk. Aim of the study: The aim of the study was to explore and describe the experiences of homosexual patients utilising primary health care (PHC services in Umlazi in the province ofKwaZulu-Natal (KZN. Method: A qualitative, exploratory, descriptive study was conducted which was contextual innature. Semi-structured interviews were conducted with 12 participants. The findings of this study were analysed using content analysis. Results: Two major themes emerged from the data analysis, namely, prejudice against homosexual patients by health care providers and other patients at the primary health care facilities, and, homophobic behaviour from primary health care personnel. Conclusion: Participants experienced prejudice and homophobic behaviour in the course of utilising PHC clinics in Umlazi, which created a barrier to their utilisation of health services located there. Nursing education institutions, in collaboration with the National Department of Health, should introduce homosexuality and anti-homophobia education programmes during the pre-service and in-service education period. Such programmes will help to familiarise health care providers with the health care needs of homosexual patients and may decrease homophobic attitudes.

Foram visitadas 12 ILPIs na cidade do Natal-RN, sendo 6 sem fins lucrativos com 260 idosos avaliados e 6 com fins lucrativos e 127 idosos. A caracterização das desigualdades no perfil dos idosos se deu a partir de dados socioeconômicos e motivo da institucionalização. Os dados foram submetidos aos testes Qui-quadrado ou t de Student com nível de significância de 5%. Como resultado, aqueles idosos analfabetos, solteiros, negros e pardos, não aposentados, sem plano de saúde, sem filhos, que não recebem visitas e que compram algo fora da instituição com o próprio dinheiro, estavam associados às ILPIs sem fins lucrativos. Ao analisar os motivos que levaram o idoso a ser institucionalizado, os conflitos familiares, o abandono e o fato de não possuir lugar para morar estiveram associados às ILPIs sem fins lucrativos. Apenas a condição “estar doente” prevaleceu como motivo principal de institucionalização em ILPIs com fins lucrativos. As condições mais desfavoráveis foram dos idosos residentes em ILPIs sem fins lucrativos, o que demonstram o reflexo da desigualdade social durante a vida desses idosos.

    2017-01-01

    Introduction HIV-associated neurocognitive disorder (HAND) is a consequence of HIV infection of the central nervous system. The prevalence ranges between 15% and 60% in different settings. Objectives This prospective study determined the prevalence of HAND at a peri-urban HIV clinic in KwaZulu-Natal. Factors associated with HAND were examined, alternate neurocognitive tools were tested against the international HIV dementia scale (IHDS) score and an association between HAND and non-adherence to antiretroviral therapy (ART) was explored. Methods Between May 2014 and May 2015, 146 ART-naïve outpatients were assessed for HAND. IHDS score ≤ 10 established a diagnosis of HAND. Functional capacity was assessed using Eastern Cooperative Oncology Group (ECOG) score. Chi-squared test was used to identify risk factors for HAND. The get-up-and-go test (GUGT) and Center for Epidemiological Studies Depression scale – revised (CESD-r) were tested against the IHDS. HIV viral load done six months after initiating ART was used as a surrogate marker for adherence to ART. Results The prevalence of HAND was 53%. In total, 99.9% of patients with HAND had no functional impairment. Age > 50 years old was associated with HAND (p = 0.003). There was no correlation between the GUGT, CESD-r and the IHDS score. HAND was not associated with non-adherence (p = 0.06). Conclusions While the prevalence of HAND is high, it is not associated with functional impairment which suggests that asymptomatic neurocognitive impairment is prevalent. Age > 50 years old is a risk factor for HAND. The GUGT and CESD-r are not useful diagnostic tools for HAND. The relationship between HAND and non-adherence should be further explored. PMID:29568639

    Full Text Available Land-cover change and habitat loss are widely recognised as the major drivers of biodiversity loss in the world. Land-cover maps derived from satellite imagery provide useful tools for monitoring land-use and land-cover change. KwaZulu-Natal, a populous yet biodiversity-rich province in South Africa, is one of the first provinces to produce a set of three directly comparable land-cover maps (2005, 2008 and 2011. These maps were used to investigate systematic land-cover changes occurring in the province with a focus on biodiversity conservation. The Intensity Analysis framework was used for the analysis as this quantitative hierarchical method addresses shortcomings of other established land-cover change analyses. In only 6 years (2005-2011, a massive 7.6% of the natural habitat of the province was lost to anthropogenic transformation of the landscape. The major drivers of habitat loss were agriculture, timber plantations, the built environment, dams and mines. Categorical swapping formed a significant part of landscape change, including a return from anthropogenic categories to secondary vegetation, which we suggest should be tracked in analyses. Longer-term rates of habitat loss were determined using additional land-cover maps (1994, 2000. An average of 1.2% of the natural landscape has been transformed per annum since 1994. Apart from the direct loss of natural habitat, the anthropogenically transformed land covers all pose additional negative impacts for biodiversity remaining in these or surrounding areas. A target of no more than 50% of habitat loss should be adopted to adequately conserve biodiversity in the province. Our analysis provides the first provincial assessment of the rate of loss of natural habitat and may be used to fulfil incomplete criteria used in the identification of Threatened Terrestrial Ecosystems, and to report on the Convention on Biological Diversity targets on rates of natural habitat loss.

    Stream habitat restoration and supplemental stocking of hatchery-reared fish have increasingly become key components of recovery plans for imperiled freshwater fish; however, determining when to discontinue stocking efforts, prioritizing restoration areas, and evaluating restoration success present a conservation challenge. In this study, we demonstrate that otolith microchemistry is an effective tool for establishing natal origin of the June Sucker Chasmistes liorus, an imperiled potamodromous fish. This approach allows us to determine whether a fish is of wild or hatchery origin in order to assess whether habitat restoration enhances recruitment and to further identify areas of critical habitat. Our specific objectives were to (1) quantify and characterize chemical variation among three main spawning tributaries; (2) understand the relationship between otolith microchemistry and tributary chemistry; and (3) develop and validate a classification model to identify stream origin using otolith microchemistry data. We quantified molar ratios of Sr:Ca, Ba:Ca, and Mg:Ca for water and otolith chemistry from three main tributaries to Utah Lake, Utah, during the summer of 2013. Water chemistry (loge transformed Sr:Ca, Ba:Ca, and Mg:Ca ratios) differed significantly across all three spawning tributaries. We determined that Ba:Ca and Sr:Ca ratios were the most important variables driving our classification models, and we observed a strong linear relationship between water and otolith values for Sr:Ca and Ba:Ca but not for Mg:Ca. Classification models derived from otolith element : Ca signatures accurately sorted individuals to their experimental tributary of origin (classification tree: 89% accuracy; random forest model: 91% accuracy) and determined wild versus hatchery origin with 100% accuracy. Overall, this study aids in evaluating the effectiveness of restoration, tracking progress toward recovery, and prioritizing future restoration plans for fishes of conservation

  6. Don't bet against the natal homing abilities of marine fishes.

    Bentzen, Paul; Bradbury, Ian R

    2016-06-01

    Whether marine fishes are capable of homing to their natal areas has long been something of an enigma. For some estuarine species or sharks (which have extended nondispersal juvenile stages or are born as relatively large, fully formed juveniles), the answer is clearly 'yes' (Thorrold et al. ; Feldheim et al. ), but for most marine fishes, the issue is much more mysterious. Many species have free-floating eggs, and most have pelagic, passively dispersing larvae. It is challenging to imagine how adult fish might navigate to a region of the ocean they experienced only as eggs or larvae, and easier to assume that such dispersal leads inexorably to high gene flow, and even panmixia. One way to resolve the conundrum would be to track fish from hatching to reproduction, but for marine fishes with tiny eggs and drifting larvae, this is notoriously difficult to do (Bradbury & Laurel ). In this issue of Molecular Ecology, Bonanomi et al. () use a creative approach to solve this challenge for Atlantic cod (Gadus morhua) populations that mingle in the vicinity of Greenland. They show that cod that disperse more than a 1000 km away from Iceland as eggs and larvae, then spend years growing on the far side of Greenland, while mixing with two local populations, return as adults to spawning areas near Iceland - and further, that this behaviour has remained stable over more than six decades. They manage this feat with a clever use of historical cod tracking data, modern genomic data and genetic analysis of decades-old DNA obtained from archived materials. Their results have important implications for our view of the biocomplexity of marine fish populations, and how we should manage them. © 2016 John Wiley & Sons Ltd.

    Full Text Available Abstract Background The differential expression pattern of microRNAs (miRNAs during mammary gland development might provide insights into their role in regulating the homeostasis of the mammary epithelium. Our aim was to analyse these regulatory functions by deriving a comprehensive tissue-specific combined miRNA and mRNA expression profile of post-natal mouse mammary gland development. We measured the expression of 318 individual murine miRNAs by bead-based flow-cytometric profiling of whole mouse mammary glands throughout a 16-point developmental time course, including juvenile, puberty, mature virgin, gestation, lactation, and involution stages. In parallel whole-genome mRNA expression data were obtained. Results One third (n = 102 of all murine miRNAs analysed were detected during mammary gland development. MicroRNAs were represented in seven temporally co-expressed clusters, which were enriched for both miRNAs belonging to the same family and breast cancer-associated miRNAs. Global miRNA and mRNA expression was significantly reduced during lactation and the early stages of involution after weaning. For most detected miRNA families we did not observe systematic changes in the expression of predicted targets. For miRNA families whose targets did show changes, we observed inverse patterns of miRNA and target expression. The data sets are made publicly available and the combined expression profiles represent an important community resource for mammary gland biology research. Conclusion MicroRNAs were expressed in likely co-regulated clusters during mammary gland development. Breast cancer-associated miRNAs were significantly enriched in these clusters. The mechanism and functional consequences of this miRNA co-regulation provide new avenues for research into mammary gland biology and generate candidates for functional validation.

    Full Text Available Background: Homosexual patients are affected by social factors in their environment, and as a result may not have easy access to existing health care services. Prejudice against homosexuality and homosexual patients remains a barrier to them seeking appropriate healthcare. The concern is that lesbians and gays might delay or avoid seeking health care when they need it because of past discrimination or perceived homophobia within the health care thereby putting their health at risk.Aim of the study: The aim of the study was to explore and describe the experiences of homosexual patients utilising primary health care (PHC services in Umlazi in the province ofKwaZulu-Natal (KZN.Method: A qualitative, exploratory, descriptive study was conducted which was contextual innature. Semi-structured interviews were conducted with 12 participants. The findings of this study were analysed using content analysis.Results: Two major themes emerged from the data analysis, namely, prejudice against homosexual patients by health care providers and other patients at the primary health care facilities, and, homophobic behaviour from primary health care personnel.Conclusion: Participants experienced prejudice and homophobic behaviour in the course of utilising PHC clinics in Umlazi, which created a barrier to their utilisation of health services located there. Nursing education institutions, in collaboration with the National Department of Health, should introduce homosexuality and anti-homophobia education programmes during the pre-service and in-service education period. Such programmes will help to familiarise health care providers with the health care needs of homosexual patients and may decrease homophobic attitudes.

  10. Evidence in sheep for pre-natal transmission of scrapie to lambs from infected mothers.

    James D Foster

    Full Text Available Natural scrapie transmission from infected ewes to their lambs is thought to occur by the oral route around the time of birth. However the hypothesis that scrapie transmission can also occur before birth (in utero is not currently favoured by most researchers. As scrapie is an opportunistic infection with multiple infection routes likely to be functional in sheep, definitive evidence for or against transmission from ewe to her developing fetus has been difficult to achieve. In addition the very early literature on maternal transmission of scrapie in sheep was compromised by lack of knowledge of the role of the PRNP (prion protein gene in control of susceptibility to scrapie. In this study we experimentally infected pregnant ewes of known PRNP genotype with a distinctive scrapie strain (SSBP/1 and looked for evidence of transmission of SSBP/1 to the offspring. The sheep were from the NPU Cheviot flock, which has endemic natural scrapie from which SSBP/1 can be differentiated on the basis of histology, genetics of disease incidence and strain typing bioassay in mice. We used embryo transfer techniques to allow sheep fetuses of scrapie-susceptible PRNP genotypes to develop in a range of scrapie-resistant and susceptible recipient mothers and challenged the recipients with SSBP/1. Scrapie clinical disease, caused by both natural scrapie and SSBP/1, occurred in the progeny but evidence (including mouse strain typing of SSBP/1 infection was found only in lambs born to fully susceptible recipient mothers. Progeny were not protected from transmission of natural scrapie or SSBP/1 by washing of embryos to International Embryo Transfer Society standards or by caesarean derivation and complete separation from their birth mothers. Our results strongly suggest that pre-natal (in utero transmission of scrapie may have occurred in these sheep.

    Because supernova remnants are short-lived, studies of neutron star X-ray binaries within supernova remnants probe the earliest stages in the life of accreting neutron stars. However, such objects are exceedingly rare: none were known to exist in our Galaxy. We report the discovery of the natal supernova remnant of the accreting neutron star Circinus X-1, which places an upper limit of t < 4600 yr on its age, making it the youngest known X-ray binary and a unique tool to study accretion, neutron star evolution, and core-collapse supernovae. This discovery is based on a deep 2009 Chandra X-ray observation and new radio observations of Circinus X-1. Circinus X-1 produces type I X-ray bursts on the surface of the neutron star, indicating that the magnetic field of the neutron star is small. Thus, the young age implies either that neutron stars can be born with low magnetic fields or that they can rapidly become de-magnetized by accretion. Circinus X-1 is a microquasar, creating relativistic jets that were thought to power the arcminute-scale radio nebula surrounding the source. Instead, this nebula can now be attributed to non-thermal synchrotron emission from the forward shock of the supernova remnant. The young age is consistent with the observed rapid orbital evolution and the highly eccentric orbit of the system and offers the chance to test the physics of post-supernova orbital evolution in X-ray binaries in detail for the first time.

    Objective: To detect whether private GPs in KwaDukuza perceive their colleagues to be practising ethically. Method: The study entailed a cross-sectional descriptive study design, in which all 30 private GPs based in KwaDukuza, KwaZulu-Natal, were asked to complete a self-administered questionnaire during 2003. The survey was done on a voluntary basis and anonymity and confidentiality was maintained. Results: Twenty-five doctors returned completed questionnaires (an 83.3% response rate. Seventy per cent perceived their peers to be practicing ethically, while 48% (12/25 reported that they did not observe any medical misconduct by their colleagues. The majority of the respondents (76% reported that they did not know of any colleague who supplemented his or her income through the over-servicing of patients. The majority of the respondents (84% also reported that their colleagues never accepted cash payments that were not declared for income tax purposes. Medically unnecessary tests are a form of unethical behaviour pertaining to over-servicing, and 64% of the respondents reported that medically unnecessary tests to satisfy patient requests were not an important reason for performing these tests. The doctors expressed high stress levels from multiple stressors in their occupation. Conclusion: GPs in KwaDukuza indicated that they were under stress, but still practised ethically. The GPs emphasised the need for more training in medical ethics at all levels of the medical career. The majority of GPs of KwaDukuza perceive their colleagues to be practising ethically.

  15. The occurrence of fig wasps in the fruits of female gynodioecious fig trees

    Fig trees are pollinated by wasp mutualists, whose larvae consume some of the plant's ovaries. Many fig species (350+) are gynodioecious, whereby pollinators generally develop in the figs of 'male' trees and seeds generally in the 'females.' Pollinators usually cannot reproduce in 'female' figs at all because their ovipositors cannot penetrate the long flower styles to gall the ovaries. Many non-pollinating fig wasp (NPFW) species also only reproduce in figs. These wasps can be either phytophagous gallers or parasites of other wasps. The lack of pollinators in female figs may thus constrain or benefit different NPFWs through host absence or relaxed competition. To determine the rates of wasp occurrence and abundance we surveyed 11 dioecious fig species on Hainan Island, China, and performed subsequent experiments with Ficus tinctoria subsp. gibbosa to identify the trophic relationships between NPFWs that enable development in female syconia. We found NPFWs naturally occurring in the females of Ficus auriculata, Ficus hainanensis and F. tinctoria subsp. gibbosa. Because pollinators occurred only in male syconia, when NPFWs also occurred in female syconia, overall there were more wasps in male than in female figs. Species occurrence concurred with experimental data, which showed that at least one phytophagous galler NPFW is essential to enable multiple wasp species to coexist within a female fig. Individuals of galler NPFW species present in both male and female figs of the same fig species were more abundant in females than in males, consistent with relaxed competition due to the absence of pollinator. However, these wasps replaced pollinators on a fewer than one-to-one basis, inferring that other unknown mechanisms prevent the widespread exploitation by wasps of female figs. Because some NPFW species may use the holes chewed by pollinator males to escape from their natal fig, we suggest that dispersal factors could be involved.

    Full Text Available This study aimed to identify the incrusting and sedentary animals associated with the hull of a tugboat active in the ports of Pernambuco and later loaned to the port of Natal, Rio Grande do Norte. Thus, areas with dense biofouling were scraped and the species then classified in terms of their bioinvasive status for the Brazilian coast. Six were native to Brazil, two were cryptogenic and 16 nonindigenous; nine of the latter were classified as established (Musculus lateralis, Sphenia fragilis, Balanus trigonus, Biflustra savartii, Botrylloides nigrum, Didemnum psammatodes, Herdmania pallida, Microscosmus exasperatus, and Symplegma rubra and three as invasive (Mytilopsis leucophaeta, Amphibalanus reticulatus, and Striatobalanus amaryllis. The presence of M. leucophaeata, Amphibalanus eburneus and A. reticulatus on the boat's hull propitiated their introduction onto the Natal coast. The occurrence of a great number of tunicate species in Natal reflected the port area's benthic diversity and facilitated the inclusion of two bivalves - Musculus lateralis and Sphenia fragilis - found in their siphons and in the interstices between colonies or individuals, respectively. The results show the role of biofouling on boat hulls in the introduction of nonindigenous species and that the port of Recife acts as a source of some species.Este trabalho objetivou identificar os animais incrustantes e sedentários associados ao casco de um rebocador que atuava nos Portos de Pernambuco e foi cedido para o Porto de Natal, Rio Grande do Norte.

    Urethral carcinoma in 2 females has been treated with irradiation together with adjunct chemotherapy. In case 1, a 73-year-old female with squamous cell carcinoma was successfully treated with irradiation of 4,000 rad and peplomycin of 60 mg intravenously given. She has been free from the disease for the past 43 months. In case 2, a 61-year-old female with transitional cell carcinoma was initially treated with irradiation of 5,000 rad together with peplomycin 90 mg, which was followed by another 5,000 rad irradiation. The tumor recurred and the patient was operated on for cystourethrectomy and partial resection of the vagina. A further chemotherapy of cisplatin, peplomycin, and mitomycin C was instituted. She died of the tumor recurrence 23 months after the first visit to our clinic. Diagnosis and treatment modalities on the female urethral carcinoma are briefly discussed. (author)

  2. Deconstructing Female Friends

    Full Text Available One of Fay Weldon’s early novels, Female Friends (1975, published at the peak of her feminist ’phase’, deconstructs female and feminine stereotypes in order to present the writer’s own views on feminism. It speaks for a generation of women, who struggle to find their place in a male-dominated world, through three protagonists, who are neither happy, nor perfect. Narrated by the character Chloe, the novel revolves around her and her friends, Grace and Marjorie, with an aim at depicting the falsehood and hypocrisy that surround female friendship. It is precisely where Weldon’s specificity as a feminist writer lies: in her rendering the imperfections of women’s characters and relationships. This paper attempts to trace such elements of ‘fayminism’ in Female Friends by resorting to the tools of the feminist critic.

    Full Text Available Between 1995 and 2000, KwaZulu-Natal province, South Africa, experienced a marked increase in Plasmodium falciparum malaria, fuelled by pyrethroid and sulfadoxine-pyrimethamine resistance. In response, vector control was strengthened and artemether-lumefantrine (AL was deployed in the first Ministry of Health artemisinin-based combination treatment policy in Africa. In South Africa, effective vector and parasite control had historically ensured low-intensity malaria transmission. Malaria is diagnosed definitively and treatment is provided free of charge in reasonably accessible public-sector health-care facilities.We reviewed four years of malaria morbidity and mortality data at four sentinel health-care facilities within KwaZulu-Natal's malaria-endemic area. In the year following improved vector control and implementation of AL treatment, malaria-related admissions and deaths both declined by 89%, and outpatient visits decreased by 85% at the sentinel facilities. By 2003, malaria-related outpatient cases and admissions had fallen by 99%, and malaria-related deaths had decreased by 97%. There was a concomitant marked and sustained decline in notified malaria throughout the province. No serious adverse events were associated causally with AL treatment in an active sentinel pharmacovigilance survey. In a prospective study with 42 d follow up, AL cured 97/98 (99% and prevented gametocyte developing in all patients. Consistent with the findings of focus group discussions, a household survey found self-reported adherence to the six-dose AL regimen was 96%.Together with concurrent strengthening of vector control measures, the antimalarial treatment policy change to AL in KwaZulu-Natal contributed to a marked and sustained decrease in malaria cases, admissions, and deaths, by greatly improving clinical and parasitological cure rates and reducing gametocyte carriage.

    Full Text Available Tsetse-transmitted trypanosomosis (nagana has been the cause of stock losses in the recent past and still presents a major problem to livestock owners in certain areas of KwaZulu- Natal, South Africa. Over 10 000 cattle mortalities were reported in the 1990 nagana outbreak. Although information on the distribution and abundance of the tsetse flies Glossina brevipalpis and Glossina austeni in KwaZulu-Natal exists, data on their vector competence are lacking. This study aimed to determine the rate of natural Trypanosoma congolense infection by field-collected as well as colony-reared flies of these species. A total of 442 field-collected G. brevipalpis and 40 G. austeni flies were dissected immediately after collection to determine their infection rates, whilst 699 G. brevipalpis and 49 G. austeni flies were fed on susceptible animals in 10 and four batches, respectively, for use in xenodiagnosis experiments. Teneral colony flies were fed on infected animals and dissected 21 days post infection to confirm their infectivity testing. Glossina austeni harboured 8% immature and mature infections. In G. brevipalpis, the infection with the immature stages was lower (1% and no mature infections were observed. Although all four batches of G. austeni transmitted T. congolense to four susceptible animals, no transmission resulted from 10 batches of G. brevipalpis fed on susceptible cattle. Colony-derived G. austeni (534 and G. brevipalpis (882 were fed on four bovines infected with different T. congolense isolates. Both G. austeni and G. brevipalpis acquired trypanosome infection from the bovines, with immature infection ranges of 20% – 33% and 1% – 4%, respectively. Parasites, however, only matured in G. austeni (average = 4%. Glossina austeni plays a larger role in the epidemiology of animal trypanosomosis in KwaZulu-Natal than G. brevipalpis and therefore more focus should be aimed at the former when control measures are implemented.

    In South Africa malaria is endemic in Mpumalanga, Limpopo and the north-eastern areas of KwaZulu-Natal provinces. South Africa has set targets to eliminate malaria by 2018 and research into complementary vector control tools such as the Sterile Insect Technique (SIT) is ongoing. It is important to understand community perceptions regarding malaria transmission and control interventions to enable development of community awareness campaign messages appropriate to the needs of the community. We aimed to assess knowledge, attitudes, and practices regarding malaria transmission to inform a public awareness campaign for SIT in Jozini Local Municipality, Mamfene in KwaZulu-Natal province. We conducted a cross-sectional survey in three communities in Mamfene, KwaZulu-Natal during 2015. A structured field piloted questionnaire was administered to 400 randomly selected heads of households. Descriptive statistics were used to summarize data. Of the 400 participants interviewed, 99% had heard about malaria and correctly associated it with mosquito bites. The sources of malaria information were the local health facility (53%), radio (16%) and community meetings (7%). Approximately 63% of the participants were able to identify three or four symptoms of malaria. The majority (76%) were confident that indoor residual spraying (IRS) kills mosquitoes and prevents infection. Bed nets were used by 2% of the participants. SIT knowledge was poor (9%), however 63% of the participants were supportive of mosquito releases for research purposes. The remaining 37% raised concerns and fears, including fear of the unknown and lack of information on the SIT. Appropriate knowledge, positive attitude and acceptable treatment-seeking behaviour for malaria were demonstrated by members of the community. Community involvement will be crucial in achieving success of the SIT and future studies should further investigate concerns raised by the community. The existing communication channels used by the

    Full Text Available Female androgenetic alopecia is the commonest cause of hair loss in women. It is characterized by a diffuse reduction in hair density over the crown and frontal scalp with retention of the frontal hairline and a characteristic pattern distribution in genetically predisposed women. Because of the uncertain relationship with the androgens Female Pattern Hair Loss (FPHL is the most preferred definition of the condition. This review has been focused on the clinical features, diagnosis and treatment alternatives of FPHL.

  11. Desert bighorn sheep lambing habitat: Parturition, nursery, and predation sites

    Fitness of female ungulates is determined by neonate survival and lifetime reproductive success. Therefore, adult female ungulates should adopt behaviors and habitat selection patterns that enhance survival of neonates during parturition and lactation. Parturition site location may play an important role in neonatal mortality of desert bighorn sheep (Ovis canadensis mexicana) when lambs are especially vulnerable to predation, but parturition sites are rarely documented for this species. Our objectives were to assess environmental characteristics at desert bighorn parturition, lamb nursery, and predation sites and to assess differences in habitat characteristics between parturition sites and nursery group sites, and predation sites and nursery group sites. We used vaginal implant transmitters (VITs) to identify parturition sites and capture neonates. We then compared elevation, slope, terrain ruggedness, and visibility at parturition, nursery, and lamb predation sites with paired random sites and compared characteristics of parturition sites and lamb predation sites to those of nursery sites. When compared to random sites, odds of a site being a parturition site were highest at intermediate slopes and decreased with increasing female visibility. Odds of a site being a predation site increased with decreasing visibility. When compared to nursery group sites, odds of a site being a parturition site had a quadratic relationship with elevation and slope, with odds being highest at intermediate elevations and intermediate slopes. When we compared predation sites to nursery sites, odds of a site being a predation were highest at low elevation areas with high visibility and high elevation areas with low visibility likely because of differences in hunting strategies of coyote (Canis latrans) and puma (Puma concolor).

    Full Text Available OBJETIVOS: descrever a teoria da atenção nutricional no pré-natal de baixo risco da rede do Sistema Único de Saúde. MÉTODOS: estudo avaliativo cujo referencial teórico foi o Modelo de Avaliação de Implementação de Love (2004, em seu terceiro estágio (oferta da intervenção. A análise de cobertura foi realizada com base em dados da Pesquisa Nacional de Demografia e Saúde de 2006 e a de componentes contemplou a elaboração dos modelos causal e lógico-operacional. RESULTADOS: a cobertura da atenção pré-natal mostrou-se quase universal no Brasil. Entretanto a não participação em processos da atenção pré-natal e nutricional relacionou-se à maior vulnerabilidade socioeconômica. A magnitude elevada de distúrbios nutricionais gestacionais e o encadeamento lógico das causas presumidas desses distúrbios e de suas consequências ressaltam a pertinência em intervir na ingestão nutricional das gestantes, dada a capacidade que se tem de agir sobre essa causa e a eficácia/efetividade demonstrada das ações. Quanto ao mérito do modelo lógico-operacional, entendeu-se que se a estrutura e o processo da atenção nutricional forem adequadamente implementados pode-se chegar aos resultados esperados. CONCLUSÕES: a descrição da teoria da intervenção e sua modelização revelam-se como etapas fundamentais à avaliação da implementação da atenção nutricional no pré-natal, na busca por seu aprimoramento.

    190 premature babies and newborn with a hypoxic or traumatic natal encephalopathy were examined in the newborn period with cranial computed tomography. 10 other neonatals with cyanotic vitia even without neurologic syndromes were included into this study. 73 of these infants were intubated for a while and supplied with air. The CT findings were compared with those of a ''control group'' of neonatals who provided externally visible malformations but no burdening perinatal anamnesis. 82 premature and neonatal babies showed abnormal morphologic basic findings. Due to kind, localisation and size of the lesion, different morphologic patterns - depending on the birth weight - can be delineated. (orig./MG) [de

    Anopheles arabiensis (Patton; Diptera: Culicidae) is a major malaria vector in the southern African region. In South Africa, effective control of this species using indoor-based interventions is reduced owing to its tendency to rest outdoors. As South Africa moves towards malaria elimination there is a need for complementary vector control strategies. One of the methods under consideration is the use of the sterile insect technique (SIT). Key to the successful implementation of an SIT programme is prior knowledge of the size and spatial distribution of the target population. Understanding mosquito population dynamics for both males and females is critical for efficient programme implementation. It is thus necessary to use outdoor-based population monitoring tools capable of sampling both sexes of the target population. In this project mosquito surveillance and evaluation of tools capable of collecting both genders were carried out at Mamfene in northern KwaZulu-Natal Province, South Africa, during the period January 2014 to December 2015. Outdoor- and indoor-resting Anopheles mosquitoes were sampled in three sections of Mamfene over the 2-yr sampling period using modified plastic buckets, clay pots and window exit traps. Morphological and molecular techniques were used for species identifications of all samples. Wild-caught adult females were tested for Plasmodium falciparum (Welch; Haemosporida: Plasmodiidae) infectivity. Out of 1,705 mosquitoes collected, 1,259 (73.8%) and 255 (15%) were identified as members of either the Anopheles gambiae complex or Anopheles funestus group respectively. An. arabiensis was the most abundant species contributing 78.8% of identified specimens. Mosquito density was highest in summer and lowest during winter. Clay pots yielded 16.3 mosquitoes per trap compared to 10.5 for modified plastic buckets over the 2-yr sampling period. P. falciparum infection rates for An. arabiensis were 0.7% and 0.5% for 2014 and 2015, respectively

    The freshwater snail Bulinus globosus is an important intermediate host of Schistosoma haematobium, the causative agent of urinary schistosomiasis. This disease is of major health concern, especially in Africa where the majority of cases have been reported. In this study the inter- and intra-genetic diversity and population genetic structure of B. globosus from nine locations in the KwaZulu-Natal province of South Africa was studied using four polymorphic microsatellite loci (BgZ1-BgZ4). Moderate genetic diversity was detected within populations with a mean diversity (HE) of 0.49±0.09. The majority of populations significantly deviated from Hardy-Weinberg equilibrium (p<0.05), due to a deficit of heterozygotes. Such deviations may be due to founder events that were caused by bottlenecks that occurred as a result of frequent droughts and flooding that these snails' habitats are exposed to. Overall, the populations studied seem to be partially inbreeders/selfers with mean estimates of 0.24/0.38. A discernable genetic structure was elucidated among populations as evident by the mean pairwise FST of 0.58±0.13. There was no significant association between genetic and geographical distance among populations, an indication of limited gene flow. This increases the chances of populations losing alleles due to genetic drift. Populations in close proximity demonstrated high genetic differentiation (58.77% total variation) due to allelic differences between them. The sample populations fell into 12 clusters, however, the populations from uMkhanyakude and uThungulu exhibited no discernable genetic structure. Genetically, the Bhobhoyi site found within the uGu district was equidistant to the two main sampling regions. Copyright © 2016 Elsevier B.V. All rights reserved.

    Male harassment of females to gain mating opportunities is a consequence of an evolutionary conflict of interest between the sexes over reproduction and is common among sexually reproducing species. Male Trinidadian guppies Poecilia reticulata spend a large proportion of their time harassing females for copulations and their presence in female social groups has been shown to disrupt female-female social networks and the propensity for females to develop social recognition based on familiarity. In this study, we investigate the behavioural mechanisms that may lead to this disruption of female sociality. Using two experiments, we test the hypothesis that male presence will directly affect social behaviours expressed by females towards other females in the population. In experiment one, we tested for an effect of male presence on female shoaling behaviour and found that, in the presence of a free-swimming male guppy, females spent shorter amounts of time with other females than when in the presence of a free-swimming female guppy. In experiment two, we tested for an effect of male presence on the incidence of aggressive behaviour among female guppies. When males were present in a shoal, females exhibited increased levels of overall aggression towards other females compared with female only shoals. Our work provides direct evidence that the presence of sexually harassing males alters female-female social behaviour, an effect that we expect will be recurrent across taxonomic groups.

    The inferred parameters of the binary black hole GW151226 are consistent with nonzero spin for the most massive black hole, misaligned from the binary's orbital angular momentum. If the black holes formed through isolated binary evolution from an initially aligned binary star, this misalignment would then arise from a natal kick imparted to the first-born black hole at its birth during stellar collapse. We use simple kinematic arguments to constrain the characteristic magnitude of this kick, and find that a natal kick v_{k}≳50  km/s must be imparted to the black hole at birth to produce misalignments consistent with GW151226. Such large natal kicks exceed those adopted by default in most of the current supernova and binary evolution models.

    Global warming is an important issue in the world which it gives a negative effect on human life. One indicator of global warming is increasing greenhouse gas i.e. carbondioxide from human activities. Deforestation and forest degradation are the second largest contributor of carbon into the atmosphere, after the use of fossil fuels by industry and transportation. As lungs of the world, forest is enable to produce renewable energy sources i.e. biomass. Forest carbon stock in above ground biomass (AGB) is the greatest effect source on deforestation and forest degradation. Therefore, it is necessary to perform a study the potential of carbon in forest. The purpose of this research is to determine carbon stock value in Batang Gadis National Park, Mandailing Natal Regency, North Sumatera Province, Indonesia. The carbon potential stored in this forest vegetation is calculated using AGB allometric equation by using data in diameter at breast height (dbh = 1.3 m), height, and density of the wood for trees. Data obtained from secondary data is Asset Assessment Report which State Controlled Forest Natural Resources Batang Gadis National Park, 2016.

    Purpose The Hlabisa pregnancy cohort was established to evaluate the effectiveness of prevention of mother-to-child transmission (PMTCT) guideline revisions. The objectives of the Hlabisa pregnancy cohort are to: (1) provide cohort-level information on maternal health up to 6 weeks postpartum in a high HIV prevalence setting; and to (2) evaluate aspects of PMTCT care that have policy relevance. Participants The pregnancy cohort is located in primary health clinics in the Hlabisa subdistrict of rural KwaZulu-Natal, South Africa. Baseline data collection between 2010 and 2014 has been completed with the enrolment of 25 608 pregnancies; age ranged from 15–49 years. Pregnant women were assessed during routine antenatal visits: first visit, follow-up 1 week later, 32 weeks (HIV test), infant delivery and 6 weeks postpartum. Demographic, pregnancy, clinical, laboratory and HIV data were collected through Department of Health interviews, laboratory tests and routine data linkage. Treatment data for HIV-infected pregnant women were linked to the Africa Centre Hlabisa HIV Treatment and Care Programme for detailed antiretroviral therapy (ART) history and laboratory tests. Findings to date The proportion of women initiated on ART post-2013 were higher (n=437; 100%) than pre-2013 (n=768; 84.2%). The proportion of women in care at 6 weeks (73.8%) was also higher post-2013 relative to earlier years (58.5%). The majority of HIV-infected pregnant women were either on lifelong ART or ART prophylaxis; pre-2013, ∼ 9.6% of women were not on any ART. Pregnancy viral load monitoring was inadequate. Future plans This cohort will be used to: (1) determine HIV acquisition risk during pregnancy and postpartum; (2) determine the effect of HIV and ART on birth outcomes; (3) examine the effect of pregnancy on virological response to ART; and (4) characterise the effect of sequential pregnancies on access to clinical care, response to prolonged ART and birth outcomes.

    2016-09-01

    Full Text Available Background: In South Africa, there is a paucity of optometrists serving the needs of the larger public sector. KwaZulu-Natal is one of the most densely populated provinces and home to several of the poorest districts. Despite an optometry school in the province, and with a lack of compulsory community service for new graduates, more optometrists are needed to serve the public sector. While studies on the recruitment and retention of medical and allied health professionals have been conducted, limited evidence exists on work trends of public sector optometrists. Methods: A cross-sectional study design using both quantitative and qualitative data collection methods was used. All public sector optometrists and local district health co-ordinators in the province were contacted, with an 80% (41 out of 51 and 75% (9 out of 12 response rate, respectively. Questionnaires containing demographic, recruitment, retention and open-ended questions were distributed by post, fax and email and via an online survey to both groups. Telephonic interviews were also conducted using semi-structured techniques. Frequency distributions, Fisher’s exact test and odds ratios were used to statistically describe the demographic data, while qualitative responses were recorded and analysed for commonly occurring themes. Results: The present public sector optometry workforce comprises mainly young (73%, black (70%, women (66%. They chose to work in the public sector to ‘make a difference’ and were attracted by ‘good working hours’ and ‘job security’. Fifty-three percent of optometrists work in the public sector due to a study bursary, for which there was a statistically significant association for race (p = 0.01, gender (p = 0.05 and background origin (p = 0.05. To aid their retention in public service, improved salaries, career progression, recognition, improved management relations and improved instrumentation were ranked highest by these optometrists

    Full Text Available Abstract Background Successful antiretroviral treatment is dependent on sustaining high rates of adherence. In the southern African context, only a handful of studies (both quantitative and qualitative have looked at the determinants including a health behaviour theory of adherence to antiretroviral therapy. The aim of this study is to assess factors including the information, motivation and behavioural skills model (IMB contributing to antiretroviral (ARV adherence six months after commencing ARVs at three public hospitals in KwaZulu-Natal, South Africa. Methods Using systematic sampling, 735 HIV-positive patients were selected prior to commencing on ART from outpatient departments from three hospitals and followed-up at six months and interviewed with a questionnaire. Results A good proportion of patients were found to be adherent using both adherence instruments (visual analog scale = VAS 82.9%; Adult AIDS Clinical Trials Group = AATCG 70.8%. After adjusting for significant socio-economic variables, both the VAS and the dose, schedule and food adherence indicator found levels of adherence amongst urban residents to be almost 3 times greater than that of rural residents. After adjusting for health-related variables, for both indicators better adherence was associated with low depression and poorer adherence was associated with poor environmental factors. Adjusted odds ratios for adherence when taking into account different behavioural variables were for both adherence indicators, discrimination experiences were associated with lower adherence, and higher scores in adherence information and behavioural skills were associated with higher adherence. For the VAS adherence indicator, higher social support scores were associated with higher adherence. For the dose, schedule and food adherence indicator, using herbal medicines for HIV was associated with lower adherence. Conclusion For the patients in this study, particularly those not living in

    2010-01-01

    ABSTRACT Background Private general practitioners (GPs) have been criticised by the lay press citing unethical practice and the acceptance of kickbacks. In 2003, the Ethics Institute of South Africa conducted a national study of all doctors and also accused private GPs of unethical practice. In countries such as South Africa, with a practice of fee-for-service payments, there may be a temptation to put material interests above the best interests of patients. Private GPs, on the other hand, are of the opinion that the press and the Ethics Institute publication have unfairly singled them out. Objective To detect whether private GPs in KwaDukuza perceive their colleagues to be practising ethically. Method The study entailed a cross-sectional descriptive study design, in which all 30 private GPs based in KwaDukuza, KwaZulu-Natal, were asked to complete a self-administered questionnaire during 2003. The survey was done on a voluntary basis and anonymity and confidentiality was maintained. Results Twenty-five doctors returned completed questionnaires (an 83.3% response rate). Seventy per cent perceived their peers to be practicing ethically, while 48% (12/25) reported that they did not observe any medical misconduct by their colleagues. The majority of the respondents (76%) reported that they did not know of any colleague who supplemented his or her income through the over-servicing of patients. The majority of the respondents (84%) also reported that their colleagues never accepted cash payments that were not declared for income tax purposes. Medically unnecessary tests are a form of unethical behaviour pertaining to over-servicing, and 64% of the respondents reported that medically unnecessary tests to satisfy patient requests were not an important reason for performing these tests. The doctors expressed high stress levels from multiple stressors in their occupation. Conclusion GPs in KwaDukuza indicated that they were under stress, but still practised ethically. The

    2013-06-01

    The underrepresentation of women in physics doctorate programs and in tenured academic positions indicates a need to evaluate what may influence their career choice and persistence. This qualitative paper examines eleven females in physics doctoral programs and professional science positions in order to provide a more thorough understanding of why and how women make career choices based on aspects both inside and outside of school and their subsequent interaction. Results indicate that female physicists experience conflict in achieving balance within their graduate school experiences and personal lives and that this then influences their view of their future careers and possible career choices. Female physicists report both early and long-term support outside of school by family, and later departmental support, as being essential to their persistence within the field. A greater focus on informal and out-of-school science activities for females, especially those that involve family members, early in life may help influence their entrance into a physics career later in life. Departmental support, through advisers, mentors, peers, and women’s support groups, with a focus on work-life balance can help females to complete graduate school and persist into an academic career.

    2013-07-01

    The aim of this review was to study "female stalking" in the sense of the specific traits characterizing the phenomenon of stalking behaviour committed by women. The main medical databases were searched (Medline, Social Science Research Network, Apa Psyc Net), and 67 articles were selected, reporting studies conducted in clinical populations, case series, reports, reviews, retrospective studies and original articles. We outline a variety of different tactics adopted by female stalkers and a lesser propensity to pass on to physical violence. Nevertheless, female stalkers are more frequently affected by erotomania, and this condition generally increases the risk of violence. If there have previously been intimate relations between the stalker and her victim, this will increase the risk of violence. In a significant proportion of female stalkers, the behavior is carried out in the occupational setting, especially in the field of psychotherapy, where the male-female ratio is reversed. No significant differences emerged between the motivations of heterosexual or homosexual stalkers. In the category of crimes of harassment committed by women, stalking, at least in Italy, seems to be among the most prominent.

This review explores themajor research findings accumulated internationally over the last decade (2003-2013 about women'sviolence and crimes. The focus of the review is the intimate partner violence (IPV and sexual violencecommitted by females, the psychopathy and violence risk assessment, and the treatment and recidivism ofthese female offenders. Although the female offender topic is too wide to review all crime typologies (childphysical abuse is not included, for example the review indicates that: there are legal and police biases inthe treatment of women offenders; women can commit the same IPV and share the motivations of maleoffenders; sexual violence has a low prevalence, but there are many limitations in this research topic;predicting the risk of non-specific violence is feasible with the available tools; psychopathy is less prevalentamong adult female offenders, although there are fewer differences with male offenders among adolescentsamples; research about treatments is very limited and there are not effectiveness evidences; and last,recidivism rates for violent crimes are very low (in cases where information is available.

    Although the rocks of the Mzumbe Gneiss suite display a close similarity to many Archaean, high-alumina tonalite-trondhjemite suites, an origin by the reactivation of a pre-existing Archaean or early Proterozoic infrastructure during the Namaqua-Natal orogenesis, can be effectively excluded. It is proposed that the Natal Metamorphic Provunce was formed by the generation and successive accretion of discrete fragments of juvenile crust onto the southern margin of the Kaapvaal craton between ∼1200 and 900 Ma. 1 fig., 9 refs

    In this study, fifteen wild boar piglets were intranasally inoculated classical swine fever virus (CSFV) strain Catalonia 01. At 5 days post-inoculation, seven other animals within 48 h of birth were put in contact with them. Viral replication and innate and specific immune responses were evaluated. Of the inoculated animals, 46.67% remained post-natally persistently infected and were apparently healthy with neither humoral nor cellular immunological responses specific to CSFV and with high viral loads in their blood, organs and body secretions. Moreover, the present data extend the time period to 48 h after birth when a moderately virulent CSFV strain could lead to post-natal persistent infection given the generation of persistently infected wild boars in the contact group (33.33%). The innate immune response to the virus, as measured by type I IFN-α in serum, was mostly not impaired in the persistently infected wild boars. Interestingly, a decrease and lack of IFN-γ-producing cells against CSFV and PHA was observed. In endemic countries where wild swine species are increasing and low and moderate virulence CSFV strains are prevalent, the possible generation of this form of disease cannot be ruled out. © 2015 Blackwell Verlag GmbH.

    Full Text Available Background: In South Africa, there is a shortage of black chartered accountants, with some progress being made in transforming the industry. Accounting firms’ managers must be prepared to effectively manage the increasing diversity of the profession. Aim: The purpose of the study was to identify the managerial competencies required by accounting firms managers to effectively manage diversity in KwaZulu-Natal. Setting: The setting for this study is accounting firms in KwaZulu-Natal. Methods: A prospective, descriptive and analytical, cross-sectional design using systematic sampling was employed. The responses of 45 accounting firms’ managers and 114 trainees were analysed. Results: Both managers and trainees perceived the six managerial competencies important in managing diversity, but the ranking order of perceived importance indicated that there are variations in ratings. Teamwork and self-management competencies were highly rated by managers, while communication and teamwork competencies were highly rated by trainees. Conclusion: The managerial competencies are vital for the accounting firms’ managers. The study suggests that the accounting firms’ managers should consider the importance given by trainees and by themselves in prioritising the most important competencies they require in managing diversity. Accounting firms are encouraged to incorporate the six managerial competencies into the job descriptions or job advertisements and in the firms’ management development programme or training and development programme as the managerial competencies will assist managers in managing the diverse workforce effectively.

    The passage of Title IX legislation in 1972 provided enormous opportunities for women to reap the benefits of sports participation. For most female athletes, sports participation is a positive experience, providing improved physical fitness, enhanced self-esteem, and better physical and mental health. Nonetheless, for a few female athletes, the desire for athletic success combined with the pressure to achieve a prescribed body weight may lead to the development of a triad of medical disorders including disordered eating, menstrual dysfunction, and low bone mineral density (BMD)--known collectively as the female athlete triad. Alone or in combination, the disorders of the triad can have a negative impact on health and impair athletic performance.

    Female sterilization is relied on by nearly one in three women aged 35-44 years in the United States. Sterilization procedures are among the most common procedures that obstetrician-gynecologists perform. The most frequent sterilization procedures include postpartum tubal ligation, laparoscopic tubal disruption or salpingectomy, and hysteroscopic tubal occlusion. The informed consent process for sterilization is crucial and requires shared decision-making between the patient and the health care provider. Counseling should include the specific risks and benefits of the specific surgical approaches. Additionally, women should be counseled on the alternatives to sterilization, including intrauterine contraceptives and subdermal contraceptive implants. Complications, including unplanned pregnancy after successful female sterilization, are rare. The objectives of this Clinical Expert Series are to describe the epidemiology of female sterilization, access to postpartum sterilization, advances in interval sterilization techniques, and clinical considerations in caring for women requesting sterilization.

    Nigeria is among the countries with a high number of annual maternal deaths partly due to low utilization of maternal health services (MHS). This study aimed to explore whether there is an association between women's level of education and the appropriate use of antenatal and delivery services. A quantitative cross-sectional study was used to analyze the Nigerian Demographic and Health Survey (NDHS) data. Information from 33,385 women aged 15 - 49 years was analyzed using Bivariate Pearson Chi square test and multiple logistic regressions. Education is statistically associated with the number of antenatal clinic visits made (AOR = 3.208; CI 2.875 - 3.578; p education will improve income, interaction with health care providers, level of autonomy to seek and pay for appropriate MHS and ultimately use of MHS and positive pregnancy outcomes.

  9. Seasonal variation of reproductive success under female philopatry and male-biased dispersal in a common vole population.

    Borkowska, Anetta

    2011-01-01

    Variation of reproductive success, an important determinant of the opportunity for sexual selection, is an outcome of competition within one sex for mating with members of the other sex. In promiscuous species, males typically compete for access to females, and their reproductive strategies are strongly related to the spatial distribution of females. I used 10 microsatellite loci and the mtDNA control region to determine seasonal differences in the reproductive success of males and females of the common vole (Microtus arvalis), one of the most numerous mammals in Europe. The sex-related spatial structure and bias in dispersal between genders were also assessed. Standardized variance of the reproductive success of females did not vary seasonally due to the continuity of female philopatry throughout the breeding season and to the constancy of the number of females reproducing successfully in each season. The males are the dispersing sex, undergoing both natal and breeding dispersal. Their standardized variance of reproductive success was significantly higher than that for females in July, when only two males monopolized 80% of the females in the population and when variance of male reproductive success was highest (I(m)=7.70). The seasonally varying and high standardized variance of male reproductive success may be explained by male-male competition for matings, coupled with seasonal changes in the age structure of the population.

    To provide Canadian gynaecologists with evidence-based direction for female genital cosmetic surgery in response to increasing requests for, and availability of, vaginal and vulvar surgeries that fall well outside the traditional realm of medically-indicated reconstructions. Published literature was retrieved through searches of PubMed or MEDLINE, CINAHL, and The Cochrane Library in 2011 and 2012 using appropriate controlled vocabulary and key words (female genital cosmetic surgery). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. There were no date or language restrictions. Searches were updated on a regular basis and incorporated in the guideline to May 2012. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table). Recommendations 1. The obstetrician and gynaecologist should play an important role in helping women to understand their anatomy and to respect individual variations. (III-A) 2. For women who present with requests for vaginal cosmetic procedures, a complete medical, sexual, and gynaecologic history should be obtained and the absence of any major sexual or psychological dysfunction should be ascertained. Any possibility of coercion or exploitation should be ruled out. (III-B) 3. Counselling should be a priority for women requesting female genital cosmetic surgery. Topics should include normal variation and physiological changes over the lifespan, as well as the possibility of unintended consequences of cosmetic surgery to the genital area.

Para a investigação da estrutura, foram incluídas todas as 31 unidades da zona urbana. No estudo do processo revisou-se os registros de pré-natal das mães com data provável de parto nos 6 meses anteriores ao início do trabalho de campo, num total de 839 formulários. A estrutura foi considerada precária (70% da ideal, principalmente devido a deficiências da planta física. Quanto ao processo, observaram-se uma baixa cobertura (53% e média de consultas de 5,3. O pré-natal foi adequado em somente 37% dos registros (Índice de Kessner. Adicionando-se exames laboratoriais e procedimentos da consulta como critérios complementares, 31% e 5% dos registros foram considerados adequados, respectivamente. De um modo geral, a qualidade do cuidado pré-natal oferecido foi precária. Mecanismos que aumentem a aderência das equipes de saúde aos procedimentos e à lógica do programa, necessitam ser desenvolvidos.

    This systematic review and meta-analysis reports the efficacy of post-natal physical activity change interventions with content coding of behaviour change techniques (BCTs). Electronic databases (MEDLINE, CINAHL and PsychINFO) were searched for interventions published from January 1980 to July 2013. Inclusion criteria were: (i) interventions including ≥1 BCT designed to change physical activity behaviour, (ii) studies reporting ≥1 physical activity outcome, (iii) interventions commencing later than four weeks after childbirth and (iv) studies including participants who had given birth within the last year. Controlled trials were included in the meta-analysis. Interventions were coded using the 40-item Coventry, Aberdeen & London - Refined (CALO-RE) taxonomy of BCTs and study quality assessment was conducted using Cochrane criteria. Twenty studies were included in the review (meta-analysis: n = 14). Seven were interventions conducted with healthy inactive post-natal women. Nine were post-natal weight management studies. Two studies included women with post-natal depression. Two studies focused on improving general well-being. Studies in healthy populations but not for weight management successfully changed physical activity. Interventions increased frequency but not volume of physical activity or walking behaviour. Efficacious interventions always included the BCTs 'goal setting (behaviour)' and 'prompt self-monitoring of behaviour'.

    Full Text Available Globally, over 300 million people are estimated to be visually impaired. Uncorrected refractive error is the primary cause of almost half of all visual impairment, resulting in the global economy losing $269 billion in productivity annually. There is a definitive level of urgency in the treatment of refractive error in children as uncorrected refractive error results in the failure of normal visual maturation, termed amblyopia, which cannot be corrected in adult life. In South Africa, the lack of appropriatechild eye care strategies has posed a serious problem to the visual health of children. In 2006, the International Centre for Eye Care Education (ICEE conducted a situational analysis of child eye care services in the province of KwaZulu-Natal (KZN. The findings of this analysis indicated a dire need for comprehensive services in the province. Stakeholders (the KwaZulu-Natal Department of Healthand the KwaZulu-Natal Department of Education were advised on the value of a short-term strategy as the underpinning of a long-term sustainable approach. This resulted in the formation of a trialliance to implement the KZN Child Eye Care Programme. Eighty (80 individuals who were previously volunteers for the KZN Department of Health were trained in vision screening. These vi-sion screeners screened 239 606 primary school children from February 2007 to May 2008. Seven percent (15 944 of the children failed the vision screening and were referred for optometric assessments. Of the 15 944 children that failed the vision screening, 10 707 children were examined by optometrists and 1083 were found to have a refractive error and were therefore supplied with spectacles. The study indicates that a short-term programme to address a backlog of services can reach many underserved children. This programme identified many challenges of implementing a vision screening programme such as poor uptake of refractive services by learners in the absence of an appropriate

    Hypertension is the most common cardiovascular disorder affecting more males in younger age groups; in the age group of 45-64, it is equally frequent in both genders, it is more common in elderly females. Blood pressure increases more in females around the menopause. Use of hormonal replacement therapy is not associated with an BP increase but, because of increased risk of coronary events, stroke, and thromboembolic events, HRT is not re-commended in CVD prevention. There is a similar decrease in BP by antihypertensive drugs in both genders as well as benefit from antihypertensive treatment. Women report about a double rate of adverse events of antihypertensive drugs. Oral contraception use is associated with a mild BP increase in most women and development of overt hypertension in about 5 %. Pre-eclampsia is associated with increased risk of developing CVD later in life (more frequent development of hypertension, myocardial infarction, and stroke).

    Full Text Available Olympic weightlifting movements and their variations are believed to be among the most effective ways to improve power, strength, and speed in athletes. This study investigated the effects of two Olympic weightlifting variations (hang cleans and hang snatches, on power (vertical jump height, strength (1RM back squat, and speed (40-yard sprint in female collegiate athletes. 23 NCAA Division I female athletes were randomly assigned to either a hang clean group or hang snatch group. Athletes participated in two workout sessions a week for six weeks, performing either hang cleans or hang snatches for five sets of three repetitions with a load of 80-85% 1RM, concurrent with their existing, season-specific, resistance training program. Vertical jump height, 1RM back squat, and 40-yard sprint all had a significant, positive improvement from pre-training to post-training in both groups (p≤0.01. However, when comparing the gain scores between groups, there was no significant difference between the hang clean and hang snatch groups for any of the three dependent variables (i.e., vertical jump height, p=0.46; 1RM back squat, p=0.20; and 40-yard sprint, p=0.46. Short-term training emphasizing hang cleans or hang snatches produced similar improvements in power, strength, and speed in female collegiate athletes. This provides strength and conditioning professionals with two viable programmatic options in athletic-based exercises to improve power, strength, and speed.

    Increasing numbers of adolescents present in adolescent gender identity services, desiring sex reassignment (SR). The aim of this study is to describe the adolescent applicants for legal and medical sex reassignment during the first two years of adolescent gender identity team in Finland, in terms of sociodemographic, psychiatric and gender identity related factors and adolescent development. Structured quantitative retrospective chart review and qualitative analysis of case files of all adolescent SR applicants who entered the assessment by the end of 2013. The number of referrals exceeded expectations in light of epidemiological knowledge. Natal girls were markedly overrepresented among applicants. Severe psychopathology preceding onset of gender dysphoria was common. Autism spectrum problems were very common. The findings do not fit the commonly accepted image of a gender dysphoric minor. Treatment guidelines need to consider gender dysphoria in minors in the context of severe psychopathology and developmental difficulties.

    Voluntary medical male circumcision (VMMC) is an integral part of South Africa's HIV prevention programme. School-going males, in particular, are considered a cost-effective target population. However, ambitious policy targets have not been achieved due to the plateau in demand for VMMC. This study documents the factors influencing demand for VMMC amongst school-going males. Data were collected from 750 learners (251 circumcised and 499 uncircumcised) from 42 secondary schools in KwaZulu-Natal, South Africa. There was a positive association between the perceived benefit of VMMC and the likelihood of undergoing circumcision (AOR: 1.41, p = 0.01). There was a negative association between self-efficacy to use condoms and likelihood of undergoing VMMC (AOR: 0.75, p concern, learners who were confident in their ability to access condoms and t use a condom with their partner were less likely to undergo VMMC.

    Full Text Available This study explored the views of professional nurses in KwaZulu-Natal, South Africa regarding the role of spirituality and spiritual care in nursing practice and investigated whether professional nurses utilize spiritually based care in nursing practice. A cross-sectional descriptive design using multistage random sampling was utilized. Five hundred and fifty questionnaires were distributed to professional nurses between December 2012 and February 2013. A total of 385 participants completed the survey questionnaire, resulting in a 77% response rate. Data was analyzed using SSPS 0.20. The data revealed that nurses see spirituality and spiritual care as an important dimension of nursing practice but need greater preparedness. Nurses need to be effectively prepared to deal with the complexity of providing ethically based personalized spiritual care in an increasingly diverse society.

    We sought to examine which socioeconomic indicators are risk factors for virologic failure among HIV-1 infected patients receiving antiretroviral therapy (ART) in KwaZulu-Natal, South Africa. A case-control study of virologic failure was conducted among patients recruited from the outpatient clinic at McCord Hospital in Durban, South Africa between October 1, 2010 and June 30, 2012. Cases were those failing first-line ART, defined as viral load >1,000 copies/mL. Univariate logistic regression was performed on sociodemographic data for the outcome of virologic failure. Variables found significant (p automobile ownership was a risk factor among males, while variables of financial insecurity (unemployment, non-spouse family paying for care, staying with family) were risk factors for women. In this cohort, financial insecurity among women and automobile ownership among men were risk factors for virologic failure. Risk factor differences between genders demonstrate limitations of generalized risk factor analysis.

  19. Effects of natal departure and water level on survival of juvenile snail kites (Rostrhamus sociabilis) in Florida

    Survival rate from fledging to breeding, or juvenile survival, is an important source of variation in lifetime reproductive success in birds. Therefore, determining the relationship between juvenile survival and environmental factors is essential to understanding fitness consequences of reproduction in many populations. With increases in density of individuals and depletion of food resources, quality of most habitats deteriorates during the breeding season. Individuals respond by dispersing in search of food resources. Therefore, to understand the influence of environmental factors on juvenile survival, it is also necessary to know how natal dispersal influences survival of juveniles. We examined effects of various environmental factors and natal dispersal behavior on juvenile survival of endangered Snail Kites (Rostrhamus sociabilis) in central and southern Florida, using a generalized estimating equations (GEEs) approach and model selection criteria. Our results suggested yearly effects and an influence of age and monthly minimum hydrologic levels on juvenile Snail Kite survival. Yearly variation in juvenile survival has been reported by other studies, and other reproductive components of Snail Kites also exhibit such variation. Age differences in juvenile survival have also been seen in other species during the juvenile period. Our results demonstrate a positive relationship between water levels and juvenile survival. We suggest that this is not a direct linear relationship, such that higher water means higher juvenile survival. The juvenile period is concurrent with onset of the wet season in the ecosystem we studied, and rainfall increases as juveniles age. For management purposes, we believe that inferences suggesting increasing water levels during the fledging period will increase juvenile survival may have short-term benefits but lead to long-term declines in prey abundance and possibly wetland vegetation structure.

  20. Is BMR repeatable in deer mice? Organ mass correlates and the effects of cold acclimation and natal altitude.

    Russell, G A; Chappell, M A

    2007-01-01

    Basal metabolic rate (BMR) is probably the most studied aspect of energy metabolism in vertebrate endotherms. Numerous papers have explored its mass allometry, phylogenetic and ecological relationships, and ontogeny. Implicit in many of these studies (and explicit in some) is the view that BMR responds to selection, which requires repeatability and heritability. However, BMR is highly plastic in response to numerous behavioral and environmental factors and there are surprisingly few data on its repeatability. Moreover, the mechanistic underpinnings of variation in BMR are unclear, despite considerable research. We studied BMR repeatability in deer mice (Peromyscus maniculatus) across intervals of 30-60 days, and also examined the influence of birth altitude (3,800 m versus 340 m) and temperature acclimation (to approximately 5 or approximately 20 degrees C) on BMR, and the relationship between BMR and organ size. Neither acclimation temperature nor natal altitude alone influenced BMR, but the combination of birth at high altitude and cold acclimation significantly increased BMR. Few visceral organ masses were correlated to BMR and most were inconsistent across natal altitudes and acclimation temperatures, indicating that no single organ 'controls' variation in BMR. In several treatment groups, the mass of the 'running motor' (combined musculoskeletal mass) was negatively correlated to BMR and the summed mass of visceral organs was positively correlated to BMR. We found no repeatability of BMR in any treatment group. That finding-in sharp contrast to high repeatability of BMR in several other small endotherms-suggests little potential for direct selection to drive BMR evolution in deer mice.
