RESUMO

BACKGROUND AND AIMS: In 2015, the country of Georgia launched an elimination program aiming to reduce the prevalence of Hepatitis C virus (HCV) infection by 90% from 5.4% prevalence (~150 000 people). During the first 2.5 years of the program, 770 832 people were screened, 48 575 were diagnosed with active HCV infection, and 41 483 patients were treated with direct-acting antiviral (DAA)-based regimens, with a >95% cure rate. METHODS: We modelled the incremental cost-effectiveness ratio (ICER) of HCV screening, diagnosis and treatment between April 2015 and November 2017 compared to no treatment, in terms of cost per quality-adjusted life year (QALY) gained in 2017 US dollars, with a 3% discount rate over 25 years. We compared the ICER to willingness-to-pay (WTP) thresholds of US$4357 (GDP) and US$871 (opportunity cost) per QALY gained. RESULTS: The average cost of screening, HCV viremia testing, and treatment per patient treated was $386 to the provider, $225 to the patient and $1042 for generic DAAs. At 3% discount, 0.57 QALYs were gained per patient treated. The ICER from the perspective of the provider including generic DAAs was $2285 per QALY gained, which is cost-effective at the $4357 WTP threshold, while if patient costs are included, it is just above the threshold at $4398/QALY. All other scenarios examined in sensitivity analyses remain cost-effective except for assuming a shorter time horizon to the end of 2025 or including the list price DAA cost. Reducing or excluding DAA costs reduced the ICER below the opportunity-cost WTP threshold. CONCLUSIONS: The Georgian HCV elimination program provides valuable evidence that national programs for scaling up HCV screening and treatment for achieving HCV elimination can be cost-effective.

RESUMO

BACKGROUND: Despite changes in the discourse around gender distributions within academic leadership, women continue to be under-represented in academia. Our study aims to identify the extent of gender disparity in the academic leadership in the top 50 North American universities and to critically analyse the contributing factors through a comprehensive theoretical framework. METHODS: We adopted the theoretical framework of leadership continuum model. A retrospective analysis of the gender of the leadership ranks was conducted between December 2018 and March 2019 for the top 50 universities in North America (2019 Quacquarelli Symonds World University Ranking system). The leadership hierarchy was classified into six tiers. RESULTS: A total of 5806 faculty members from 45 US and five Canadian universities were included. Women were overall less likely to be in a senior leadership role than men (48.7% vs 51.3%; p value=0.05). Women accounted for fewer positions than men for resident/chancellor (23.8% vs 76.2%; p value<0.001), vice-president/vice-chancellor (36.3% vs 63.7%; p value<0.001), vice provost (42.7% vs 57.3%; p value=0.06), dean (38.5% vs 61.5%; p value<0.001) and associate dean (48.2% vs 51.8%; p-value=0.05). Women however were in a greater proportion in the assistant dean positions (63.8% vs 36.2%; p value<0.001). CONCLUSION: Leadership gender imbalance is trans-organisational and transnational within the top 50 universities of North America and progressively widens towards the top leadership pyramid. This correlates with the lack of women leadership progress and sustainability in later cycles of the leadership continuum model (beyond assistant dean).

RESUMO

BACKGROUND: In April 2015, in collaboration with the US Centers for Disease Control and Prevention and Gilead Sciences, the country of Georgia embarked on the world's first hepatitis C elimination program. We aimed to assess progress toward elimination targets 3 years after the start of the elimination program. METHODS: We constructed a hepatitis C virus (HCV) care cascade for adults in Georgia, based on the estimated 150 000 persons aged ≥18 years with active HCV infection. All patients who were screened or entered the treatment program during April 2015-March 2018 were included in the analysis. Data on the number of persons screened for HCV were extracted from the national HCV screening database. For the treatment component, we utilized data from the Georgia National HCV treatment program database. Available treatment options included sofosbuvir and ledipasvir/sofosbuvir-based regimens. RESULTS: Since April 2015, a cumulative 974 817 adults were screened for HCV antibodies; 86 624 persons tested positive, of whom 61 925 underwent HCV confirmatory testing. Among the estimated 150 000 adults living with chronic hepatitis C in Georgia, 52 856 (35.1%) were diagnosed, 45 334 (30.2%) initiated treatment with direct-acting antivirals, and 29 090 (19.4%) achieved a sustained virologic response (SVR). Overall, 37 256 persons were eligible for SVR assessment; of these, only 29 620 (79.5%) returned for evaluation. The SVR rate was 98.2% (29 090/29 620) in the per-protocol analysis and 78.1% (29 090/37 256) in the intent-to-treat analysis. CONCLUSIONS: Georgia has made substantial progress in the path toward eliminating hepatitis C. Scaling up of testing and diagnosis, along with effective linkage to treatment services, is needed to achieve the goal of elimination.

RESUMO

BACKGROUND & AIMS: Georgia, with a high prevalence of HCV infection, launched the world's first national hepatitis C elimination program in April 2015. A key strategy is the identification, treatment, and cure of the estimated 150,000 HCV-infected people living in the country. We report on progress and key challenges from Georgia's experience. METHODS: We constructed a care cascade by analyzing linked data from the national hepatitis C screening registry and treatment databases during 2015-2018. We assessed the impact of reflex hepatitis C core antigen (HCVcAg) testing on rates of viremia testing and treatment initiation (i.e. linkage to care). RESULTS: As of December 31, 2018, 1,101,530 adults (39.6% of the adult population) were screened for HCV antibody, of whom 98,430 (8.9%) tested positive. Of the individuals who tested positive, 78,484 (79.7%) received viremia testing, of whom 66,916 (85.3%) tested positive for active HCV infection. A total of 52,576 people with active HCV infection initiated treatment and 48,879 completed their course of treatment. Of the 35,035 who were tested for cure (i.e., sustained virologic response [SVR]), 34,513 (98.5%) achieved SVR. Reflex HCVcAg testing, implemented in March 2018, increased rates of monthly viremia testing by 97.5% among those who screened positive for anti-HCV, however, rates of treatment initiation decreased by 60.7% among diagnosed viremic patients. CONCLUSIONS: Over one-third of people living with HCV in Georgia have been detected and linked to care and treatment, however, identification and linkage to care of the remaining individuals with HCV infection is challenging. Novel interventions, such as reflex testing with HCVcAg, can improve rates of viremia testing, but may result in unintended consequences, such as decreased rates of treatment initiation. Linked data systems allow for regular review of the care cascade, allowing for identification of deficiencies and development of corrective actions. LAY SUMMARY: This report describes progress in Georgia's hepatitis C elimination program and highlights efforts to promote hepatitis C virus screening and treatment initiation on a national scale. Georgia has made progress towards eliminating hepatitis C, treating over 50,000 people, approximately one-third of the number infected, and achieving cure for 98.5% of those tested. However, identifying infected individuals and linking them to care remains challenging. Novel approaches to increase diagnostic testing can have unintended consequences further down the care cascade.

RESUMO

BACKGROUND: In April 2015, the government of Georgia (country) initiated the world's first national hepatitis C elimination program. An analysis of blood donor infectious screening data was conducted to inform a strategic plan to advance blood transfusion safety in Georgia. STUDY DESIGN AND METHODS: Descriptive analysis of blood donation records (2015-2017) was performed to elucidate differences in demographics, donor type, remuneration status, and seroprevalence for infectious markers (hepatitis C virus antibody [anti-HCV], human immunodeficiency virus [HIV], hepatitis B virus surface antigen [HBsAg], and Treponema pallidum). For regression analysis, final models included all variables associated with the outcome in bivariate analysis (chi-square) with a p value of less than 0.05. RESULTS: During 2015 to 2017, there were 251,428 donations in Georgia, representing 112,093 unique donors; 68.5% were from male donors, and 51.2% of donors were paid or replacement (friends or family of intended recipient). The overall seroprevalence significantly declined from 2015 to 2017 for anti-HCV (2.3%-1.4%), HBsAg (1.5%-1.1%), and T. pallidum (1.1%-0.7%) [p < 0.0001]; the decline was not significant for HIV (0.2%-0.1%). Only 41.0% of anti-HCV seropositive donors underwent additional testing to confirm viremia. Infectious marker seroprevalence varied by age, sex, and geography. In multivariable analysis, first-time and paid donor status were associated with seropositivity for all four infectious markers. CONCLUSION: A decline during the study period in infectious markers suggests improvement in blood safety in Georgia. Areas that need further improvement are donor recruitment, standardization of screening and diagnostic follow-up, quality assurance, and posttransfusion surveillance.

RESUMO

In 2016, the World Health Organization (WHO) set hepatitis elimination targets of 90% reduction in incidence and 65% reduction in mortality worldwide by 2030 (1). Hepatitis B virus (HBV) and hepatitis C virus (HCV) infection prevalences are high in Uzbekistan, which lacks funding for meeting WHO's targets. In the absence of large financial donor programs for eliminating HBV and HCV infections, insufficient funding is an important barrier to achieving those targets in Uzbekistan and other low- and middle-income countries. A pilot program using a catalytic funding model, including simplified test-and-treat strategies, was launched in Tashkent, Uzbekistan, in December 2019. Catalytic funding is a mechanism by which the total cost of a program is paid for by multiple funding sources but is begun with upfront capital that is considerably less than the total program cost. Ongoing costs, including those for testing and treatment, are covered by payments from 80% of the enrolled patients, who purchase medications at a small premium that subsidizes the 20% who cannot afford treatment and therefore receive free medication. The 1-year pilot program set a target of testing 250,000 adults for HBV and HCV infection and treating all patients who have active infection, including those who had a positive test result for hepatitis B surface antigen (HBsAg) and those who had a positive test result for HCV core antigen. During the first 3 months of the program, 24,821 persons were tested for HBV and HCV infections. Among those tested, 1,084 (4.4%) had positive test results for HBsAg, and 1,075 (4.3%) had positive test results for HCV antibody (anti-HCV). Among those infected, 275 (25.4%) initiated treatment for HBV, and 163 (15.2%) initiated treatment for HCV, of whom 86.5% paid for medications and 13.5% received medications at no cost. Early results demonstrate willingness of patients to pay for treatment if costs are low, which can offset elimination costs. However, improvements across the continuum of care are needed to recover the upfront investment. Lessons learned from this program, including the effectiveness of using simplified test-and-treat guidelines, general practitioners in lieu of specialist physicians, and innovative financing to reduce costs, can guide similar initiatives in other countries and help curb the global epidemic of viral hepatitis, especially among low- and middle-income countries.

RESUMO

The country of Georgia initiated an ambitious national hepatitis C elimination program. To facilitate elimination, a national hospital hepatitis C screening program was launched in November 2016, offering all inpatients screening for HCV infection. This analysis assesses the effectiveness of the first year of the screening program to identify HCV-infected persons and link them to care. Data from Georgia's electronic Health Management Information System and ELIMINATION-C treatment database were analyzed for patients aged ≥18 years hospitalized from November 1, 2016 to October 31, 2017. We described patient characteristics and screening results and compared linked-to-care patients to those not linked to care, defined as having a test for viremia following an HCV antibody (anti-HCV) positive hospital screening. Of 291,975 adult inpatients, 252,848 (86.6%) were screened. Of them, 4.9% tested positive, with a high of 17.4% among males aged 40-49. Overall, 19.8% of anti-HCV+ patients were linked to care, which differed by sex (20.6% for males vs. 18.4% for females; p = .019), age (23.9% for age 50-59 years vs. 10.7% for age ≥ 70 years; p < .0001), and length of hospitalization (21.8% among patients hospitalized for 1 day vs. 16.1% for those hospitalized 11+ days; p = .023). Redundant screening is a challenge; 15.6% of patients were screened multiple times and 27.6% of anti-HCV+ patients had a prior viremia test. This evaluation demonstrates that hospital-based screening programs can identify large numbers of anti-HCV+ persons, supporting hepatitis C elimination. However, low linkage-to-care rates underscore the need for screening programs to be coupled with effective linkage strategies.

RESUMO

BACKGROUND: Georgia has one of the highest HCV prevalence in the world and launched the world's first national HCV elimination programs in 2015. Georgia set the ambitious target of diagnosing 90% of people living with HCV, treating 95% of those diagnosed and curing 95% of treated patients by 2020. We report outcomes of Sofosbuvir (SOF) based treatment regimens in patients with chronic HCV infection in Georgia. METHODS: Patients with cirrhosis, advanced liver fibrosis and severe extrahepatic manifestations were enrolled in the treatment program. Initial treatment consisted of SOF plus ribavirin (RBV) with or without pegylated interferon (INF). Sustained virologic response (SVR) was defined as undetectable HCV RNA at least 12 weeks after the end of treatment. SVR were calculated using both per-protocol and modified intent-to-treat (mITT) analysis. Results for patients who completed treatment through 31 October 2018 were analyzed. RESULTS: Of the 7342 patients who initiated treatment with SOF-based regimens, 5079 patients were tested for SVR. Total SVR rate was 82.1% in per-protocol analysis and 74.5% in mITT analysis. The lowest response rate was observed among genotype 1 patients (69.5%), intermediate response rate was achieved in genotype 2 patients (81.4%), while the highest response rate was among genotype 3 patients (91.8%). Overall, SOF/RBV regimens achieved lower response rates than IFN/SOF/RBV regimen (72.1% vs 91.3%, P < 0.0001). In multivariate analysis being infected with HCV genotype 2 (RR =1.10, CI [1.05-1.15]) and genotype 3 (RR = 1.14, CI [1.11-1.18]) were associated with higher SVR. Patients with cirrhosis (RR = 0.95, CI [0.93-0.98]), receiving treatment regimens of SOF/RBV 12 weeks, SOF/RBV 20 weeks, SOF/RBV 24 weeks and SOF/RBV 48 weeks (RR = 0.85, CI [0.81-0.91]; RR = 0.86, CI [0.82-0.92]; RR = 0.88, CI [0.85-0.91] and RR = 0.92, CI [0.87-0.98], respectively) were less likely to achieve SVR. CONCLUSIONS: Georgia's real world experience resulted in high overall response rates given that most patients had severe liver damage. Our results provide clear evidence that SOF plus IFN and RBV for 12 weeks can be considered a treatment option for eligible patients with all three HCV genotypes. With introduction of next generation DAAs, significantly improved response rates are expected, paving the way for Georgia to achieve HCV elimination goals.

RESUMO

In April 2015, the country of Georgia, with a high prevalence of hepatitis C virus (HCV) infection (5.4% of the adult population, approximately 150,000 persons), embarked on the world's first national elimination program (1,2). Nearly 40% of these infections are attributed to injection drug use, and an estimated 2% of the adult population currently inject drugs, among the highest prevalence of injection drug use in the world (3,4). Since 2006, needle and syringe programs (NSPs) have been offering HCV antibody testing to persons who inject drugs and, since 2015, referring clients with positive test results to the national treatment program. This report summarizes the results of these efforts. Following implementation of the elimination program, the number of HCV antibody tests conducted at NSPs increased from an average of 3,638 per year during 2006-2014 to an average of 21,551 during 2015-2018. In 2017, to enable tracking of clinical outcomes among persons who inject drugs, NSPs began encouraging clients to voluntarily provide their national identification number (NIN), which all citizens must use to access health care treatment services. During 2017-2018, a total of 2,780 NSP clients with positive test results for HCV antibody were identified in the treatment database by their NIN. Of 494 who completed treatment and were tested for HCV RNA ≥12 weeks after completing treatment, 482 (97.6%) were cured of HCV infection. Following the launch of the elimination program, Georgia has made much progress in hepatitis C screening among persons who inject drugs; recent data demonstrate high cure rates achieved in this population. Testing at NSPs is an effective strategy for identifying persons with HCV infection. Tracking clients referred from NSPs through treatment completion allows for monitoring the effectiveness of linkage to care and treatment outcomes in this population at high risk, a key to achieving hepatitis C elimination in Georgia. The program in Georgia might serve as a model for other countries.

RESUMO

Worldwide, an estimated 257 million persons are living with chronic hepatitis B virus (HBV) infection (1). To achieve the World Health Organization (WHO) goals for elimination of HBV infection worldwide by 2030, defined by WHO as 90% reduction in incidence and 65% reduction in mortality, access to treatment will be crucial. WHO estimated the care cascade* for HBV infection, globally and by WHO Region. The patent and licensing status of entecavir and tenofovir, two WHO-recommended medicines for HBV treatment, were examined using the Medicines Patent Pool MedsPaL† database. The international price of tenofovir was estimated using WHO's global price reporting mechanism (GPRM), and for entecavir from a published study (2). In 2016, among the estimated 257 million persons infected with HBV worldwide, approximately 27 million (10.5%) were aware of their infection, an estimated 4.5 million (16.7%) of whom were on treatment. In 2017, all low- and middle-income countries (LMICs) could legally procure generic entecavir, and all but two LMICs could legally procure generic tenofovir. The median price of WHO-prequalified generic tenofovir on the international market fell from $208 per year in 2004 to $32 per year in 2016. In 2015, the lowest reported price of entecavir was $427 per year of treatment (2). Increased availability of generic antivirals effective in treating chronic HBV infection has likely improved access to treatment. Taking advantage of reductions in price of antivirals active against HBV infection could further increase access to treatment. Regular analysis of the hepatitis B treatment care cascade can assist in monitoring progress toward HBV elimination goals.

RESUMO

Identifying patients at-risk for HIV infection, such as men who have sex with men (MSM), is an important step in providing HIV testing and prevention interventions. It is unknown how primary care providers (PCPs) assess MSM status and related HIV-risk factors. We analyzed data from a panel-derived web-based survey for healthcare providers conducted in 2014 to describe how PCPs in the U.S. determined their patients' MSM status. We calculated adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) to describe PCP characteristics associated with systematically determining MSM status (i.e., PCP used "a patient-completed questionnaire" or "routine verbal review of sex history"). Among the 1008 PCPs, 56% determined MSM status by routine verbal review of sexual history; 41% by patient disclosure; 39% by questions driven by symptoms/history; 23% by using a patient-completed questionnaire, and 9% didn't determine MSM status. PCPs who systematically determined MSM status (n=665; 66%) were more likely to be female (aPR=1.16, CI=1.06-1.26), to be affiliated with a teaching hospital (aPR=1.15, CI=1.06-1.25), to routinely screen all patients aged 13-64 for HIV (aPR=1.29, CI=1.18-1.41), and to estimate that 6% or more of their male patients are MSM (aPR=1.14, CI=1.01-1.30). The majority of PCPs assessed MSM status and HIV risk factors through routine verbal reviews of sexual history. Implementing a systematic approach to identify MSM status and assess risk may allow PCPs to identify more patients needing frequent HIV testing and other preventive services, while mitigating socio-cultural barriers to obtaining such information.

RESUMO

BACKGROUND: Condom-less sex can increase the risk of acquiring or transmitting HIV. AIM: To characterize the prevalence of condom use at the most recent sex act and identify factors associated with use of a condom at the most recent sex act in adults in the United States. METHODS: Data from the cross-sectional National Survey of Family Growth from cycles 2006 through 2010 and 2011 through 2013 were analyzed for sexually active men and women 18 to 44 years old who reported having sex (vaginal, anal, or oral) with an opposite-sex partner in the past 12 months. HIV-related sexual risk behaviors (SRBs) in the past 12 months included sex with at least four opposite-sex partners; exchanging sex for money or drugs; sex with an injection drug user; sex with an HIV-positive person; sex with a man who previously had sex with a man (women only); sex with a man (men only); or sex with a partner who had sex with other partners. OUTCOMES: The outcome for this analysis was condom use at the most recent anal or vaginal sex act. RESULTS: Overall prevalence of condom use was 24.8%; only 33.8% of adults with at least one SRB reported the use of a condom. Only 46.4% of unmarried or single men (vs 14.7% married or cohabitating men) and 32.3% unmarried or single women (vs 14.1% married or cohabitating women) with SRBs reported using a condom at the most recent sexual encounter and were less likely to use a condom at the most recent sexual encounter compared with those who did not report SRBs. We did not find a significant relation between using a condom and SRBs in married or cohabitating men and women. STRENGTHS AND LIMITATIONS: Our analysis adds to the literature on how condom use varies by marital status. We measured the use of condoms at the most recent sexual act, which might not reflect an individual's previous behavior of condom use. Nonetheless, condom use at the most recent sexual act has been documented in previous studies as a valid proxy of condom use over time. CONCLUSION: Continued efforts are needed to promote condom use in heterosexual adults in the United States, particularly those at high risk for HIV, namely individuals engaging in anal sexual acts and with multiple sex partners.

RESUMO

Georgia, a country in the Caucasus region of Eurasia, has a high prevalence of hepatitis C virus (HCV) infection. In April 2015, with technical assistance from CDC, Georgia embarked on the world's first program to eliminate hepatitis C, defined as a 90% reduction in HCV prevalence by 2020 (1,2). The country committed to identifying infected persons and linking them to care and curative antiviral therapy, which was provided free of charge through a partnership with Gilead Sciences (1,2). From April 2015 through December 2016, a total of 27,595 persons initiated treatment for HCV infection, among whom 19,778 (71.7%) completed treatment. Among 6,366 persons tested for HCV RNA ≥12 weeks after completing treatment, 5,356 (84.1%) had no detectable virus in their blood, indicative of a sustained virologic response (SVR) and cure of HCV infection. The number of persons initiating treatment peaked in September 2016 at 4,595 and declined during October-December. Broader implementation of interventions that increase access to HCV testing, care, and treatment for persons living with HCV are needed for Georgia to reach national targets for the elimination of HCV.

RESUMO

Few groups in the United States (US) are as heavily affected by HIV as men who have sex with men (MSM), yet many MSM remain unaware of their infection. HIV diagnosis is important for decreasing onward transmission and promoting effective treatment for HIV, but the cost-effectiveness of testing programs is not well-established. This study reports on the costs and cost-utility of the MSM Testing Initiative (MTI) to newly diagnose HIV among MSM and link them to medical care. Cost and testing data in 15 US cities from January 2013 to March 2014 were prospectively collected and combined to determine the cost-utility of MTI in each city in terms of the cost per Quality Adjusted Life Years (QALY) saved from payer and societal perspectives. The total venue-based HIV testing costs ranged from $18,759 to $564,284 for nine to fifteen months of MTI implementation. The cost-saving threshold for HIV testing of MSM was $20,645 per new HIV diagnosis. Overall, 27,475 men were tested through venue-based MTI, of whom 807 (3 %) were newly diagnosed with HIV. These new diagnoses were associated with approximately 47 averted HIV infections. The cost per QALY saved by implementation of MTI in each city was negative, indicating that MTI venue-based testing was cost-saving in all cities. The cost-utility of social network and couples testing strategies was, however, dependent on whether the programs newly diagnosed MSM. The cost per new HIV diagnosis varied considerably across cities and was influenced by both the local cost of MSM testing implementation and by the seropositivity rate of those reached by the HIV testing program. While the cost-saving threshold for HIV testing is highly achievable, testing programs must successfully reach undiagnosed HIV-positive individuals in order to be cost-effective. This underscores the need for HIV testing programs which target and engage populations such as MSM who are most likely to have undiagnosed HIV to maximize programmatic benefit and cost-utility.

RESUMO

Objective To assess the combined effect of consanguineous and child marriages (CCM) on children health, which has not previously been explored, either globally or locally. Methods We analyzed secondary data from a series of cross-sectional, nationally representative Pakistan Demographic and Health Surveys 1990-91, 2006-07, and 2012-13. A total of 5406 mothers with 10,164 children were included in the analysis. Child health was assessed by variables such as history of diarrhea, acute respiratory infection (ARI), ARI with fever, Under-5 child mortality (U5CM) and small-size birth (SSB). Associations among variables were assessed by calculating unadjusted Odd Ratios (OR) and adjusted OR (AOR). Results A majority (n = 6,247, 61%) of the births were to mothers having CCM as compare to non-CCM (3917, 39%). There was a significant association between CCM and U5CM during 1990-91 (AOR 1.24, 95% CI 1.03-1.49) and 2006-07 (AOR 1.25, 95% CI 1.05-1.51), and infant mortality in 1990-91 (AOR 1.39, 95% CI 1.05-1.85) and 2006-07 (AOR 1.61, 95% CI 1.17-2.21). A significant association was also found between CCM and SSB infants in the period 2006-07 (AOR 1.19, 95% CI 1.01-1.42) and 2012-13 (AOR 1.22, 95% CI 1.02-1.46). We noted no effect of CCM on diarrhea, ARI, and ARI with fever. Conclusion CCM increases the likelihood of U5CM, infant mortality and SSB infants. Further quantitative and qualitative research should be conducted to assess the effects of environmental, congenital and genetic factors on the health of children born to mothers in CCM.

RESUMO

The aim of this study was to determine the association between maternal utilisation of health-care services and socio-demographic factors among reproductive-age women in Pakistan. We used the sample of ever-married reproductive-age women (n = 7446) from the Pakistan Demographic and Health Survey (PDHS), 2012-13. We measured maternal utilisation of health-care services by using three dependent variables: number of antenatal care (ANC) visits, delivery assistance by a skilled health provider, and delivery in a health-care facility. Around 36.6% of women had made four or more ANC visits, 59% had received assistance from skilled health providers during delivery, and 55.3% had given birth in a health-care facility. On multivariable logistic regression, all three variables were positively associated with education and wealth, and negatively associated with birth order and women's autonomy. Policymakers and health planners may use our findings to develop efficient strategies, particularly for uneducated women and those with poor economic status, to improve the utilisation of maternal health-care services in Pakistan.

RESUMO

The country of Georgia has a high prevalence of hepatitis C virus (HCV) infection, associated with exposures to HCV in health care settings with inadequate infection control and unsafe injections among persons who inject drugs (1). In April 2015, in collaboration with CDC and other partners, Georgia embarked on a program to eliminate HCV infection, subsequently defined as achieving a 90% reduction in prevalence by 2020. The initial phase of the program focused on providing HCV treatment to infected persons with advanced liver disease and at highest risk for HCV-associated morbidity and mortality. By April 27, 2016, a total of 27,392 HCV-infected persons registered for the program, 8,448 (30.8%) started treatment, and 5,850 patients (69.2%) completed HCV treatment. Among patients completing treatment who were eligible for posttreatment testing, 2,398 received polymerase chain reaction (PCR) testing for HCV at least 12 weeks after completion of treatment; 1,980 (82.6%) had no detectable virus, indicative of a sustained virologic response* (i.e., cure). Major challenges to achieving elimination remain, including the need to increase access to care and treatment services and implement a comprehensive approach to prevention and control of HCV infection. As a global leader in this effort, the Georgia HCV Elimination Program can help pave the way for other countries experiencing high rates of HCV infection to undertake similar initiatives.

RESUMO

BACKGROUND: Child marriage (<18 years) is prevalent in Pakistan which is associated with negative health outcomes including intimate partner violence (IPV). Our aim is to describe the types and circumstances of IPV against women who were married as children in urban slums of Lahore, Pakistan. METHODS: Women of reproductive age (15-49 years) who were married prior to 18 years, for at least 5 years were recruited from most populous slum areas of Lahore, Pakistan. Themes for the interview guide were developed using published literature and everyday observations of the researchers. Interviews were conducted by trained interviewers in Urdu language and were translated into English. The interviews were tape-recorded, transcribed, analyzed and categorized into themes. RESULTS: All 19 participants were married between 11 and 17 years. Most respondents were uneducated, poor and were working as housemaids. Majority of participants experienced verbal abuse, and threatened, attempted and completed physical violence by their husbands. A sizeable number of women reported unwanted sexual encounters by their husbands. Family affairs particularly issues with in-laws, poor house management, lack of proper care of children, bringing insufficient dowry, financial problems, an act against the will of husband, and inability to give birth to a male child were some of the reasons narrated by the participants which led to IPV against women. CONCLUSIONS: Women married as children are vulnerable to IPV. Concerted efforts are needed from all sectors of society including academia, public health experts, policy makers and civil society to end the child marriage practice in Pakistan.

RESUMO

We aimed to discern paternal factors associated with neonatal deaths and births with low weight, independent of maternal and other socio-demographic factors. We analyzed the nationally representative sample of 5,724 ever-married women of reproductive age (15-49 years) who delivered their last child during the past 5 years preceding the Pakistan Demographic and Health Survey 2006-2007. We assessed adverse birth outcomes using two variables i.e. neonatal deaths (<28 days) and small size births (as a proxy for birth weight). Associations between paternal factors and adverse birth outcomes were assessed by calculating unadjusted and adjusted odds ratios using logistic regression models after controlling for maternal and socio-demographic factors. The analysis was performed by using the statistical package for social sciences (SPSS) version 17. About 4.5 % mothers reported neonatal deaths and 34 % had small size births (SSB). We found that fathers involved in manual occupation were more likely to have neonatal deaths than fathers involved in managerial/professional jobs (adjusted odds ratio (aOR): 1.64; 95 % Confidence Interval (CI) 1.01, 3.55). Similarly, fathers who belonged to poorer wealth index had higher risk of SSB (aOR: 1.62; 95 % CI 1.18, 2.22). Additionally, consanguinity was a major risk factor which was associated with neonatal deaths (aOR: 1.73; 95 % CI 1.09, 2.74) and SSB (aOR: 1.25; 95 % CI 1.03, 1.55). Fathers' occupation including unemployment and consanguinity were associated with increased risk of adverse birth outcomes. Further studies are warranted to discern other paternal risk factors related to adverse birth outcomes.
