Recovery after caesarean birth: a qualitative study of women's accounts in Victoria, Australia
<p>Abstract</p> <p>Background</p> <p>The caesarean section rate is increasing globally, especially in high income countries. The reasons for this continue to create wide debate. There is good epidemiological evidence on the maternal morbidity associated with caesarean section. Few studies have used women's personal accounts of their experiences of recovery after caesarean. The aim of this paper is to describe women's accounts of recovery after caesarean birth, from shortly after hospital discharge to between five months and seven years after surgery.</p> <p>Method</p> <p>Women who had at least one caesarean birth in a tertiary hospital in Victoria, Australia, participated in an interview study. Women were selected to ensure diversity in experiences (type of caesarean, recency), caesarean and vaginal birth, and maternal request caesarean section. Interviews were audiotaped and transcribed verbatim. A theoretical framework was developed (three Zones of clinical practice) and thematic analysis informed the findings.</p> <p>Results</p> <p>Thirty-two women were interviewed who between them had 68 births; seven women had experienced both caesarean and vaginal births. Three zones of clinical practice were identified in women's descriptions of the reasons for their first caesareans. Twelve women described how, at the time of their first caesarean section, the operation was performed for potentially life-saving reasons (Central Zone), 11 described situations of clinical uncertainty (Grey Zone), and nine stated they actively sought surgical intervention (Peripheral Zone).</p> <p>Thirty of the 32 women described difficulties following the postoperative advice they received prior to hospital discharge and their physical recovery after caesarean was hindered by a range of health issues, including pain and reduced mobility, abdominal wound problems, infection, vaginal bleeding and urinary incontinence. These problems were experienced across the three zones of clinical practice, regardless of the reasons women gave for their caesarean.</p> <p>Conclusion</p> <p>The women in this study reported a range of unanticipated and unwanted negative physical health outcomes following caesarean birth. This qualitative study adds to the existing epidemiological evidence of significant maternal morbidity after caesarean section and underlines the need for caesarean section to be reserved for circumstances where the benefit is known to outweigh the harms.</p
Very advanced maternal age and morbidity in Victoria, Australia: a population based study
BACKGROUND: In Australia, approximately 0.1% of births occur to women 45 years or older and this rate has been increasing in recent years. There are however, few population based studies examining perinatal outcomes among this age group. The aim of this study was to determine the maternal and perinatal outcomes of pregnancies in women aged 45 years or older compared to women aged 30–34 years. METHODS: Data on births at 20 or more weeks’ gestation were obtained from the Victorian Perinatal Data Collection for the years 2005 and 2006. We examined selected maternal and perinatal outcomes for women of very advanced maternal age (VAMA) aged 45 years or older (n = 217) and compared them to women aged 30–34 years (n = 48,909). Data were summarised using numbers and percentages. Categorical data were analysed by Chi-square tests and Fisher’s exact test. Comparisons are presented using unadjusted odds ratios, 95 percent confidence intervals (CIs) and p-values. RESULTS: Women aged 45 years and older had higher odds of gestational diabetes (OR 2.05; 95% CI 1.3–3.3); antepartum haemorrhage (OR 1.89; 95% CI 1.01–3.5), and placenta praevia (OR 4.88; 95% CI 2.4–9.5). The older age-group also had higher odds of preterm birth between 32–36 weeks (OR 2.61; 95% CI 1.8–3.8); low birth-weight (<2,500 gr) (OR 2.22; 95% CI 1.5–3.3) and small for gestational age (OR 1.53; 95% CI 1.0–2.3). Stratified analysis revealed that VAMA was most strongly associated with caesarean section in primiparous women (OR 8.24; 95% CI 4.5, 15.4) and those using ART (OR 5.75; 95% CI 2.5, 13.3), but the relationship persisted regardless of parity, ART use and plurality. Low birthweight was associated with VAMA only in first births (OR 3.90; 95% CI 2.3, 6.6), while preterm birth was more common in older women for both first (OR 3.13; 95% CI 1.8, 5.3) and subsequent (OR 2.08; 95% CI 1.2, 3.5) births, and for those having singleton births (OR 2.11; 95% CI 1.3, 3.4), and those who did not use ART (OR 2.10; 95% CI 1.3, 3.4). Preterm birth was very common in multiple births and following ART use, regardless of maternal age. CONCLUSIONS: This study demonstrates that women aged 45 years and older, in Victoria, Australia, have higher rates of pregnancy and perinatal complications, compared to women aged 30–34 years
New archaeological discoveries in north-central Timor-Leste indicate sociocultural adaptations to landscape change during the Holocene
During the Holocene, Wallacea saw dramatic sociocultural changes during the Pre-ceramic, Neolithic, Metal-age, and Colonial periods, as well as climatic and associated environmental changes that affected the landscapes and ecologies of islands. These environmental and cultural processes appear to have influenced human socioeconomic adaptations throughout the archipelago. Here, we present new anthropological and archaeological data demonstrating the effects of these processes. Excavations at the cave site of Hatu Saur on the north coast of Timor-Leste have revealed a deep archaeological sequence that dates from ca. 10,500 years until the present. The site contains extensive assemblages of faunal remains, as well as stone artifacts, revealing settlement patterns that were influenced by sea level change and estuarine infilling after 7 ka. The sequence encompasses the beginning of the Neolithic in Timor-Leste, some 3500 years ago, and the period from ca. 700 years ago when outside influences, including Chinese and Makassar traders and Dutch and Portuguese colonization, greatly affected the indigenous culture and economy on the island of Timor, reflected in the material culture remains from Hatu Saur. The archaeological findings complement related anthropological research in the region that highlights unique local mythologies of settlement origins and their contested histories
Agnoprotein Is an Essential Egress Factor during BK Polyomavirus Infection.
BK polyomavirus (BKPyV; hereafter referred to as BK) causes a lifelong chronic infection and is associated with debilitating disease in kidney transplant recipients. Despite its importance, aspects of the virus life cycle remain poorly understood. In addition to the structural proteins, the late region of the BK genome encodes for an auxiliary protein called agnoprotein. Studies on other polyomavirus agnoproteins have suggested that the protein may contribute to virion infectivity. Here, we demonstrate an essential role for agnoprotein in BK virus release. Viruses lacking agnoprotein fail to release from host cells and do not propagate to wild-type levels. Despite this, agnoprotein is not essential for virion infectivity or morphogenesis. Instead, agnoprotein expression correlates with nuclear egress of BK virions. We demonstrate that the agnoprotein binding partner α-soluble N-ethylmaleimide sensitive fusion (NSF) attachment protein (α-SNAP) is necessary for BK virion release, and siRNA knockdown of α-SNAP prevents nuclear release of wild-type BK virions. These data highlight a novel role for agnoprotein and begin to reveal the mechanism by which polyomaviruses leave an infected cell
Forty-thousand years of maritime subsistence near a changing shoreline on Alor Island (Indonesia)
We report archaeological findings from a significant new cave site on Alor Island, Indonesia, with an in situ basal date of 40,208-38,454 cal BP. Twenty thousand years older than the earliest Pleistocene site previously known from this island, Makpan retains dense midden deposits of marine shell, fish bone, urchin and crab remains, but few terrestrial species; demonstrating that protein requirements over this time were met almost exclusively from the sea. The dates for initial occupation at Makpan indicate that once Homo sapiens moved into southern Wallacea, settlement of the larger islands in the archipelago occurred rapidly. However, the Makpan sequence also suggests that the use of the cave following initial human arrival was sporadic prior to the terminal Pleistocene about 14,000 years ago, when occupation became intensive, culminating in the formation of a midden. Like the coastal sites on the larger neighbouring island of Timor, the Makpan assemblage shows that maritime technology in the Pleistocene was highly developed in this region. The Makpan assemblage also contains a range of distinctive personal ornaments made on Nautilus shell, which are shared with sites located on Timor and Kisar supporting connectivity between islands from at least the terminal Pleistocene. Makpan's early inhabitants responded to sea-level change by altering the way they used both the site and local resources. Marine food exploitation shows an initial emphasis on sea-urchins, followed by a subsistence switch to molluscs, barnacles, and fish in the dense middle part of the sequence, with crabs well represented in the later occupation. This new record provides further insights into early modern human movements and patterns of occupation between the islands of eastern Nusa Tenggara from ca. 40 ka.The fieldwork and dating for this project was funded by an

Angiotensin II for the Treatment of Vasodilatory Shock
BACKGROUND Vasodilatory shock that does not respond to high-dose vasopressors is associated with high mortality. We investigated the effectiveness of angiotensin II for the treatment of patients with this condition. METHODS We randomly assigned patients with vasodilatory shock who were receiving more than 0.2 mu g of norepinephrine per kilogram of body weight per minute or the equivalent dose of another vasopressor to receive infusions of either angiotensin II or placebo. The primary end point was a response with respect to mean arterial pressure at hour 3 after the start of infusion, with response defined as an increase from baseline of at least 10 mm Hg or an increase to at least 75 mm Hg, without an increase in the dose of background vasopressors. RESULTS A total of 344 patients were assigned to one of the two regimens; 321 received a study intervention (163 received angiotensin II, and 158 received placebo) and were included in the analysis. The primary end point was reached by more patients in the angiotensin II group (114 of 163 patients, 69.9%) than in the placebo group (37 of 158 patients, 23.4%) (odds ratio, 7.95; 95% confidence interval [CI], 4.76 to 13.3; P<0.001). At 48 hours, the mean improvement in the cardiovascular Sequential Organ Failure Assessment (SOFA) score (scores range from 0 to 4, with higher scores indicating more severe dysfunction) was greater in the angiotensin II group than in the placebo group (-1.75 vs. -1.28, P = 0.01). Serious adverse events were reported in 60.7% of the patients in the angiotensin II group and in 67.1% in the placebo group. Death by day 28 occurred in 75 of 163 patients (46%) in the angiotensin II group and in 85 of 158 patients (54%) in the placebo group (hazard ratio, 0.78; 95% CI, 0.57 to 1.07; P = 0.12). CONCLUSIONS Angiotensin II effectively increased blood pressure in patients with vasodilatory shock that did not respond to high doses of conventional vasopressors.

Contemporary caesarean section theory : risk, uncertainty and fear
In this chapter, we discuss several theoretical concepts relevant to an explanation of the contemporary use of caesarean section. We contend that, in order to provide safe and appropriate maternity care, midwives need to understand the multiple factors that influence the increasing use of caesarean birth by care givers and women. To begin, the prominent discourses of the competing ideologies of childbirth and the general changes to maternity care practices that have occurred over time are discussed. We then describe three ‘zones of clinical practice’ that help us understand traditional and contemporary reasons for caesarean section, as described in the scientific literature. From there, we critique three commonly reported approaches to decision-making in health care and suggest the limitations of these approaches in relation to decision-making for interventions, such as caesarean section. The theoretical framework developed, encompassing three zones of clinical practice and three decision-making styles draws on findings from an interview study of women’s experiences of caesarean section from an interview study of women’s experiences of caesarean section. With increasing use of technologies such as caesarean section, discourses of risk, fear, uncertainty, trust and confidence are shown to influence decision-making in childbirth
