RESUMEN

BACKGROUND: Safe blood is essential for the care of patients with life-threatening anemia and hemorrhage. Low blood donation rates, inefficient testing procedures, and other supply chain disruptions in blood administration affect patients in low-resource settings across Sub-Saharan countries, including Kenya. Most efforts to improve access to transfusion have been unidimensional, usually focusing on only point along the blood system continuum, and have excluded community stakeholders from early stages of intervention development. Context-appropriate interventions to improve the availability of safe blood at the point of use in low-resource settings are of paramount importance. Thus, this protocol proposes a multifaceted approach to characterize the Kenyan blood supply chain through quantitative and qualitative analyses as well as an industrial engineering approach. METHODS: This study will use a mixed-methods approach in addition to engineering process mapping, modeling and simulation of blood availability in Kenya. It will be guided by a multidimensional three-by-three-by-three matrix: three socioeconomic settings, three components of the blood system continuum, and three levels of urgency of blood transfusion. Qualitative data collection includes one-on-one interviews and focus group discussions with stakeholders across the continuum to characterize ground-level deficits and potential policy, systems, and environment (PSE) interventions. Prospectively-collected quantitative data will be used to estimate blood collection and transfusion of blood. We will create a process map of the blood system continuum to model the response to PSE changes proposed by stakeholders. Lastly, we will identify those PSE changes that may have the greatest impact on blood transfusion availability, accounting for differences across socioeconomic settings and levels of urgency. DISCUSSION: Identifying and prioritizing community-driven interventions to improve blood supply in low-resource settings are of utmost importance. Varied constraints in blood collection, processing, delivery, and use make each socioeconomic setting unique. Using a multifaceted approach to understand the Kenyan blood supply and model the response to stakeholder-proposed PSE changes may lead to identification of contextually appropriate intervention targets to meet the transfusion needs of the population.

RESUMEN

BACKGROUND: The supply of blood in many low- and middle-income nations in Sub-Saharan Africa (SSA) does not meet the patient care needs. Lack and delay of blood transfusion cause harm to patients and slow the rate of progress in other parts of the health system. Recognizing the power of implementation science, the BLOODSAFE Program was initiated which supports three SSA research study teams and one data coordinating center (DCC) with the goal to improve access to safe blood transfusion in SSA. STUDY DESIGN AND METHODS: The study team in Ghana is focusing on studying and decreasing iron deficiency in blood donors and evaluating social engagement of blood donors through different approaches. The study team in Kenya is building a "vein to vein" workflow model to elucidate and devise strategies to overcome barriers to blood donation and improve infrastructural components of blood product production and use. The Malawi team is studying the infectious disease ramifications of blood donation as well as blood donor retention strategies aimed at blood donors who commence their donation career in secondary schools. RESULTS AND DISCUSSION: Together the project teams and the DCC work as a consortium to support each other through a shared study protocol that will study donor motivations, outcomes, and adverse events across all three countries. The BLOODSAFE Program has the potential to lead to generalizable improvement approaches for increasing access to safe blood in SSA as well as mentoring and building the research capacity and careers of many investigators.

RESUMEN

BACKGROUND: Human migration is a worldwide phenomenon that receives considerable attention from the media and healthcare authorities alike. A significant proportion of children seen at public sector health facilities in South Africa (SA) are immigrants, and gaps have previously been noted in their healthcare provision. The objective of the study was to describe the characteristics and differences between the immigrant and SA children admitted to Kalafong Provincial Tertiary Hospital (KPTH), a large public sector hospital in the urban Gauteng Province of SA. METHODS AND FINDINGS: A cross-sectional study was conducted over a 4-month period during 2016 to 2017. Information was obtained through a structured questionnaire and health record review. The enrolled study participants included 508 children divided into 2 groups, namely 271 general paediatric patients and 237 neonates. Twenty-five percent of children in the neonatal group and 22.5% in the general paediatric group were immigrants. The parents/caregivers of the immigrant group had a lower educational level (p < 0.0001 neonatal and paediatric), lower income (neonatal p < 0.001; paediatric p = 0.024), difficulty communicating in English (p < 0.001 neonatal and paediatric), and were more likely residing in informal settlements (neonatal p = 0.001; paediatric p = 0.007) compared to the SA group. In the neonatal group, there was no difference in the number of antenatal care (ANC) visits, type of delivery, gestational age, and birth weight. In the general paediatric group, there was no difference in immunisation and vitamin A supplementation coverage, but when comparing growth, the immigrant group had more malnutrition compared to the SA group (p = 0.029 for wasting). There was no difference in the prevalence of maternal human immunodeficiency virus (HIV) infection, with equally good prevention of mother-to-child transmission (PMTCT) coverage. There was also no difference in reported difficulties by immigrants in terms of access to healthcare (neonatal p = 0.379; paediatric p = 0.246), although a large proportion (10%) of the neonates of immigrant mothers were born outside a medical facility. CONCLUSIONS: Although there were health-related differences between immigrant and SA children accessing in-hospital care, these were fewer than expected. Differences were found in parental educational level and socioeconomic factors, but these did not significantly affect ANC attendance, delivery outcomes, immunisation coverage, HIV prevalence, or PMTCT coverage. The immigrant population should be viewed as a high-risk group, with potential problems including suboptimal child growth. Health workers should advocate for all children in the community they are serving and promote tolerance, respect, and equal healthcare access.

RESUMEN

STUDY OBJECTIVE: To establish face and construct validity for a novel variation of American College of Obstetrics and Gynecology "Flowerpot Model" for transvaginal hysterectomy (TVH) surgical simulation with improved vesicovaginal dissection during surgical education simulation. DESIGN: Cross-sectional face and construct validation study using the "Flowerpot Model." The vesicovaginal dissection plane was modified to include additional felt and balloon materials to simulate the bladder. SETTING: Single academic center. PARTICIPANTS: Fourteen residents and fellows, postgraduate year (PGY) 2 to 6, subdivided into junior (n = 8) with ≤10 prior TVH surgeries and senior groups (n = 6) with >10 prior TVH surgeries performed. INTERVENTIONS: All subjects watched a brief introductory video and then were filmed simulating a TVH. MEASUREMENTS AND MAIN RESULTS: For face validity, subjects completed an anatomic checklist and pre/post simulation satisfaction survey. For construct validation, 2 independent, blinded expert surgeons (M.A. and J.M.) graded films using the Global Rating Scale of Operative Performance (GRS). Primary outcome was mean GRS between groups. The junior group consisted of PGY 2 to 3 with ≤ 10 prior TVH, median 7.5 (interquartile range [IQR] 6.75) and senior group PGY 3 to 6 with >10 TVH, median 19 (IQR 10) (p <.01). Subjects were "satisfied" or "very satisfied" with bladder and anterior peritoneal fold simulation (92%) and found vesicovaginal dissection "realistic" (100%). GRS score was significantly different between groups (juniors, 19.5 [IQR 5] vs seniors, 28.5 [IQR 8.5]; p = .048). Intergrader correlation was high (ρ = 0.87, p <.01). Surgeon volume of prior TVH was not significantly correlated to average GRS score, ρ = 0.49 (p = .10). The model improved comfort and confidence scores in the junior group more than senior group (p = .04), but senior group still had higher post simulation confidence scores than the junior group (p = .02). CONCLUSION: Face and construct validity with the modified Flowerpot Model was demonstrated. This low fidelity model is capable of simulation of a TVH with a novel vesicovaginal dissection. Prior surgical experience was not correlated to GRS score or time to procedure completion.

RESUMEN

The objective was to assess the feasibility and safety of the ̳Every Second Matters for Emergency and Essential Surgery - Ketamine' (ESM-Ketamine) package in support of obstetric and gynecologic emergency and essential surgery when no anesthetist is available. A consecutive case series was conducted in twelve hospitals across five severely resource-limited counties in Kenya. 530 women underwent obstetric or gynecological operative procedures supported by non-anesthetist clinicians using the ESM-Ketamine package between November 1, 2013 and September 30, 2017. Main outcomes included reasons for ESM-Ketamine activations and ketamine-related adverse events. There were two (0.4%) prolonged (>30 seconds) oxygen desaturations below 92%. Brief oxygen desaturations (<30 seconds) below 92% occurred in 15 (2.8%) cases and 113 (21.3%) were administered diazepam to treat hallucinations or agitation. There were no ketamine-related deaths or injuries. The ESM- Ketamine package appears feasible and safe for use in support of obstetric and gynecologic surgeries when no anesthetist is available.

RESUMEN

BACKGROUND: Septic incomplete miscarriages remain a cause of maternal deaths in South Africa. There was an initial decline in mortality when a strict protocol based approach and the Choice of Termination of Pregnancy Act in South Africa were implemented in this country. However, a recent unpublished audit at the Pretoria Academic Complex (Kalafong and Steve Biko Academic Hospitals) suggested that maternal mortality due to this condition is increasing. The objective of this investigation is to do a retrospective audit with the purpose of identifying the reasons for the deteriorating mortality index attributed to septic incomplete miscarriage at Steve Biko Academic Hospital. METHODS: A retrospective audit was performed on all patients who presented to Steve Biko Academic Hospital with a septic incomplete miscarriage from 1(st) January 2008 to 31(st) December 2010. Data regarding patient demographics, initial presentation, resuscitation and disease severity was collected from the "maternal near-miss"/SAMM database and the patient's medical record. The shock index was calculated for each patient retrospectively. RESULTS: There were 38 SAMM and 9 maternal deaths during the study period. In the SAMM group 86.8% and in the maternal death group 77.8% had 2 intravenous lines for resuscitation. There was no significant improvement in the mean blood pressure following resuscitation in the SAMM group (p 0.67), nor in the maternal death group (p 0.883). The shock index before resuscitation was similar in the two groups but improved significantly following resuscitation in the SAMM group (p 0.002). Only 31.6% in the SAMM group and 11.1% in the maternal death group had a complete clinical examination, including a speculum examination of the cervix on admission. No antibiotics were administered to 21.1% in the SAMM group and to 33.3% in the maternal death group. CONCLUSION: The strict protocol management for patients with septic incomplete miscarriage was not adhered to. Physicians should be trained to recognise and react to the seriously ill patient. The use of the shock index in the identification and management of the critically ill pregnant patient needs to be investigated.

RESUMEN

Although many countries still face opposition to the legislation of artificial tanning beds, all Australian states and territories have announced a total ban on commercial tanning beds. A combination of epidemiological and policy-centered research, powerful personal stories, and the active advocacy of prominent academics, cancer organizations, and grassroots community campaigners contributed to the decisions to first legislate standards and then ban all commercial tanning beds. We have illustrated that incremental change can be an effective pathway to securing substantial public health reforms.

RESUMEN

Prior investigations suggest that maternal HIV/AIDS poses significant challenges to young children. This study investigates the relationships between mothers' psychological functioning, parenting, and children's behavioral outcomes and functioning in a population of women living with HIV (N = 361) with a child between the ages of 6 and 10 years in Tshwane, South Africa. Utilizing path analysis, findings revealed that maternal depression is related to increased parenting stress and parent-child dysfunction, maternal coping is related to parenting style, and maternal coping, parenting style and stress, and parent-child dysfunction are associated with children's behavior and functioning, with parenting emerging as an important mediator. These findings suggest that interventions for women living with HIV and their children should not only address maternal psychological functioning (depression and coping), but should also focus on parenting, promoting a positive approach.

RESUMEN

This study aimed to determine whether there have been shifts in news coverage of sun protection issues over a 12-year period in the context of an evolving skin cancer prevention agenda. A content analysis was performed on all relevant articles (N = 552) published in the two metropolitan daily newspapers in Melbourne, Australia, from 2001 to 2012. Coding variables included theme, article type, prominence, spokesperson and topic slant. Articles were collapsed into three 4-year blocks and a series of chi-square analyses conducted to examine changes over time in coverage of topical issues (i.e. vitamin D and sunbeds) and established sun protection themes [i.e. health effects of ultraviolet (UV) exposure, education/prevention, attitudes/behaviour]. Coverage of vitamin D and sunbed issues increased over time and became more positive for sun protection objectives. The proportion of articles reporting on established sun protection themes remained steady over time (range: 36-38%) and there were no changes observed in the way these topics were presented in the news media. These results highlight that potentially competing sun protection issues that emerge over time need not pose a threat to existing skin cancer prevention programmes but instead can provide opportunities to further spread programme messages while increasing credibility.

RESUMEN

Involvement of male partners may increase adherence to and improve outcomes of programs to prevent mother-to-child HIV transmission (PMTCT). Greater understanding of factors impeding male voluntary HIV counseling and testing (VCT) is needed. A cross-sectional study was conducted in Tshwane, South Africa. Semi-structured interviews were completed with men whose partners had recently been pregnant. Of 124 men who participated, 94% believed male HIV testing was important, but 40% had never been tested. Of those tested, 32% were tested during the pregnancy, while 37% were tested afterward. Fifty-eight percent of men reported that their female partners had disclosed their test results during pregnancy. A man's likelihood of testing during pregnancy was associated with prior discussion of testing in PMTCT, knowing the female partner had tested, and her disclosure of the test result (all p<0.05). In terms of increasing male-partner HIV testing rates, 74% of the men reported they would respond favorably to a written invitation for VCT from their partners. Based on themes that emerged during the interviews, six partner invitation cards to encourage male involvement in PMTCT were designed. Responses to the cards were elicited from 158 men and 409 women. One invitation card framed by the themes of fatherhood and the baby was selected by 41% of men and 31% of women as the most likely for women undergoing PMTCT to bring to their male partners and the most successful at encouraging men to be tested. In conclusion, this study found that a substantial proportion of men whose partners were recently pregnant had never been tested themselves; of those who had tested, most had done so only after the pregnancy. Encouraging partner communication and clinic attendance using an invitation card could facilitate increased male testing and participation in PMTCT.

RESUMEN

Structured interviews were conducted with 224 HIV-positive women diagnosed during pregnancy, at antenatal clinics in Tshwane, South Africa, in order to investigate the use of coping strategies during the first two years after diagnosis. Interviews were conducted between one and four weeks after diagnosis during pregnancy, with three follow-up interviews conducted post-partum. Coping strategies were assessed with an adapted version of the Brief COPE. It was found that active coping was used more often than avoidant coping throughout the study period. Active coping increased over time, while avoidant coping decreased at first but increased again between 6 and 21 months after diagnosis. The most frequently used coping strategies included acceptance, direct action, positive reframing, religion and distraction. At first, women coped through internalised strategies. Over time, outward-focused strategies developed. Avoidant coping patterns differed from previous research indicating that women diagnosed during pregnancy deal with the consequences of HIV after the baby is born. Recommendations for mental health services are made.

RESUMEN

Adults with HIV are living longer due to earlier diagnosis and increased access to antiretroviral medications. Therefore, fewer young children are being orphaned and instead, are being cared for by parents who know they are HIV positive, although they may be asymptomatic. Presently, it is unclear whether the psychological functioning of these young children is likely to be affected or, alternatively, whether it is only when a mother is ill, that children suffer adverse effects. We, thus, aimed to compare the behavior and psychological functioning of young children (aged 6-10 years) of HIV-positive and HIV-negative mothers. We also aimed to examine the association between HIV status disclosure and child outcomes. This study uses cross-sectional data from the baseline assessment of a randomized controlled trial conducted in Tshwane, South Africa. Participants (n=509) and their children were recruited from area health clinics. Among the 395 mothers with HIV, 42% reported symptoms of HIV disease. Multivariate linear regression models suggested that after adjusting for socio-demographic characteristics, children of HIV-positive mothers had significantly greater externalizing behaviors than children of HIV-negative mothers. Importantly, children whose mothers were symptomatic had greater internalizing and externalizing behaviors compared with children of HIV-negative mothers, but this was not true for children of asymptomatic mothers. Additionally, among children of HIV-positive mothers, those who had been told their mothers were sick compared with children who had been told nothing had less internalizing and externalizing behaviors and improved daily living skills. This study, therefore, provides evidence that maternal HIV disease can affect the behaviors of young children in South Africa but, importantly, only when the mothers are symptomatic from their disease. Furthermore, results suggest that disclosure of maternal illness but not HIV status was associated with improved behavior and psychological functioning among young children.

RESUMEN

Tanning beds used according to the manufacturer's instructions expose the user to health risks, including melanoma and other skin cancers. Applying the MPOWER model (monitor, protect, offer alternatives, warn, enforce, and raise taxes), which has been used in tobacco control, to tanning bed reform could reduce the number of people at risk of diseases associated with tanning bed use. Among the tactics available to government are restricting the use of tanning beds by people under age 18 and those with fair skin, increasing the price of tanning bed services through taxation, licensing tanning bed operators, and banning unsupervised tanning bed operations.

RESUMEN

OBJECTIVE: Using a qualitative design this study aimed to (1) explore the experience of people living with osteoarthritis (OA), (2) gain an understanding of their navigation of the health system and, (3) explore their opinions on the role of exercise and joint replacement surgery for the management of OA. METHODS: Purposive sampling was used to recruit 26 participants with knee OA, aged 45 years and over, from Tasmania, Australia. Semi-structured interviews were audio-recorded, transcribed, coded, and thematically analysed to document participant understanding and experience of OA and their opinions on the role of exercise and surgery in managing OA. RESULTS: Of the 26 participants, 80% (n = 21) were female with a mean age of 66 years. The main theme identified was that individuals with knee OA were navigating a maze of OA treatments. Three related subthemes were that participants: (i) perceived their general practitioner did not have an ongoing role in their OA care, (ii) self-directed their management and, (iii) sampled from a 'smorgasbord' of treatment options, including low-value care options. Two other major themes were: the role of exercise for OA management, and surgery as a last resort. CONCLUSION: Our findings suggest that OA patients may not be choosing consistent, high-value care for their OA. This highlights the importance of an evidence-based multi-disciplinary approach to guide patients to self-manage their OA and support their navigation of the health system. Reducing emphasis on the pathway to surgery and streamlining access to conservative management strategies may assist people to receive high-value care.

RESUMEN

Postpartum hemorrhage (PPH) is the leading cause of maternal mortality in Kenya. The aim of this study was to measure quality and timeliness of care for PPH in a sample of deliveries in referral hospitals in Kenya. We conducted direct observations of 907 vaginal deliveries in three Kenyan hospitals from October 2018 through February 2019, observing the care women received from admission for labor and delivery through hospital discharge. We identified cases of "suspected PPH", defined as cases in which providers indicated suspicion of and/or took an action to manage abnormal bleeding. We measured adherence to World Health Organization and Kenyan guidelines for PPH risk assessment, prevention, identification, and management and the timeliness of care in each domain. The rate of suspected PPH among the observed vaginal deliveries was 9% (95% Confidence Interval: 7% - 11%). Health care providers followed all guidelines for PPH risk assessment in 7% (5% - 10%) of observed deliveries and all guidelines for PPH prevention in 4% (3% - 6%) of observed deliveries. Lowest adherence was observed for taking vital signs and for timely administration of a prophylactic uterotonic. Providers did not follow guidelines for postpartum monitoring in any of the observed deliveries. When suspected PPH occurred, providers performed all recommended actions in 23% (6% - 40%) of cases. Many of the critical actions for suspected PPH were performed in a timely manner, but, in some cases, substantial delays were observed. In conclusion, we found significant gaps in the quality of risk assessment, prevention, identification, and management of PPH after vaginal deliveries in referral hospitals in Kenya. Efforts to reduce maternal morbidity and mortality from PPH should emphasize improvements in the quality of care, with a particular focus on postpartum monitoring and timely emergency response.

RESUMEN

The prevention of mother-to-child HIV transmission (PMTCT) is a complex challenge in heavily affected and resource-limited settings such as South Africa. Management of PMTCT requires a cascade of interventions that need to be addressed to effectively decrease the risk of HIV transmission to infants. This PMTCT cascade includes incremental components that can be shaped and influenced by the patient-provider relationship. The relationship that a pregnant woman has with her care providers may possibly affect decisions that she makes concerning her antenatal care and may, in turn, influence the quality of the care provided. A patient-provider relationship scale (PPRS) was developed in Pretoria, South Africa with two aims: first, to quantify the patient-provider relationship in an antenatal population in a resource-limited setting and provide preliminary evidence of its reliability and validity; and second, to determine whether the patient-provider relationship has an effect on PMTCT. The instrument was administrated in a cross-sectional pilot study to a group of women at discharge after delivery (n=192) at two major hospitals in South West Tshwane. Statistical analysis of the instrument showed high reliability (α=0.91) and preliminary evidence of its validity including significant associations with participants' attitudes regarding the functioning of the clinics and a single statement (the clinic staff "know me as a person," R=0.47, p<0.001) that has been shown previously to have a significant association with adherence to antiretroviral treatment. For HIV-positive participants, the PPRS was significantly associated with statements related to important components of the PMTCT cascade. In addition, those with substantially inadequate antenatal care (≤2 visits) and those who did not initiate highly active antiretroviral therapy, although eligible, had significantly poorer PPRS scores. The PPRS is a potentially useful, context-appropriate instrument that could have an important role in future research focused on improving PMTCT and decreasing the risk of HIV infection in children.

RESUMEN

Surface ultraviolet (UV) radiation plays an important role in human health. Increased exposure to UV radiation increases the risk of skin cancer. In Australia, public campaigns to prevent skin cancer include the promotion of daily UV forecasts. If all other atmospheric factors are equal, stratospheric ozone decreases result in UV increases. Given that Australia still has the highest skin cancer rates in the world, it is important to monitor Australia's stratospheric ozone and UV radiation levels over time because of the effects cumulative exposure can have on humans. In this paper, two long-term ozone datasets derived from surface and satellite measurements, a radiation code and atmospheric meteorological fields are used to calculate clear-sky UV radiation over a 50-year period (1959-2009) for Australia. The deviations from 1970-1980 levels show that clear-sky UV is on the rise. After the 1990s, an overall annual increase from 2 to 6% above the 1970-1980 levels was observed at all latitudes. Examining the summer and winter deviations from 1970-1980 showed that the winter signal dominated the annual changes, with winter increases almost twice those in summer. With ozone levels not expected to recover to pre-depletion levels until the middle of this century, UV levels are expected to continue to rise. Combined with Australians favoring an outdoor life-style, when temperatures are warmer, under high levels of UV, the associated risk of skin cancer will increase.

RESUMEN

Hemorrhage is responsible for at least 40% of deaths after trauma and 27% of maternal deaths worldwide. Patients with hemorrhagic shock require attentive critical care and transfusion of blood products. Access to a safe and affordable blood supply is critical to providing safe surgical care. Traumatic injury, obstetric hemorrhage, and upper gastrointestinal bleed are the main causes of severe bleeding requiring transfusion. This article discusses the presentation and management of these causes across the world and provides a brief overview of the current challenges in maintaining a global blood supply.

RESUMEN

BACKGROUND/PURPOSE: The study aimed to establish compliance of indoor tanning businesses with 2009 legislation, particularly with requirements to provide information on skin cancer and exclude people under 18 or with fair skin. METHODS: Compliance was tested through surveys and in-person visits to 30 businesses in Melbourne, Australia. Research assistants presented as potential customers with different profiles: young adults eligible to use a sunbed, young adults with fair skin, under age customers who prompted with their age and under age customers who concealed their age and claimed to be 18 if asked. RESULTS: Communicating the risks of skin cancer during the visit improved from 70% in 2003, prior to the introduction of legislation, to 97% in 2009. While there were improvements in restricting access to sunbeds among high-risk groups, compliance of indoor tanning businesses with age and skin type restrictions remained less than optimal. Almost half (47%) allowed access to fair-skinned research assistants, compared with 90% in 2003. Only one of the 30 operators allowed access to a teenager who prompted with her age; in 2003, 52% of under age teenagers were granted access without parental consent. However, when teenagers concealed their age or claimed to be 18, 80% of operators granted them access. CONCLUSIONS: The findings suggest that regulation of the indoor tanning industry is a better approach to this health issue than voluntary standards and/or education. Nonetheless, inadequate compliance with requirements to exclude high-risk groups lends weight to calls for stricter monitoring and enforcement, or an absolute ban.

RESUMEN

The authors of this study evaluated a structured 10-session psychosocial support group intervention for newly HIV-diagnosed pregnant South African women. Participants were expected to display increases in HIV disclosure, self-esteem, active coping and positive social support, and decreases in depression, avoidant coping, and negative social support. Three hundred sixty-one pregnant HIV-infected women were recruited from four antenatal clinics in Tshwane townships from April 2005 to September 2006. Using a quasi-experimental design, assessments were conducted at baseline and two and eight months post-intervention. A series of random effects regression analyses were conducted, with the three assessment points treated as a random effect of time. At both follow-ups, the rate of disclosure in the intervention group was significantly higher than that of the comparison group (p<0.001). Compared to the comparison group at the first follow-up, the intervention group displayed higher levels of active coping (t=2.68, p<0.05) and lower levels of avoidant coping (t=-2.02, p<0.05), and those who attended at least half of the intervention sessions exhibited improved self-esteem (t=2.11, p<0.05). Group interventions tailored for newly HIV positive pregnant women, implemented in resource-limited settings, may accelerate the process of adjusting to one's HIV status, but may not have sustainable benefits over time.
