Update: Malaria, U.S. Armed Forces, 2021

Malaria infection remains an important health threat to U.S. service members who are located in endemic areas because of long-term duty assignments, participation in shorter-term contingency operations, or personal travel. In 2021, a total of 20 service members were diagnosed with or reported to have malaria. This was the lowest number of annual cases during the 10-year surveillance period (i.e., January 2012-December 2021) and represents a 28.6% decrease from the 28 cases identified in 2020. The relatively low numbers of cases during 2012-2021 mainly reflect decreases in cases acquired in Afghanistan, a reduction largely due to the progressive withdrawal of U.S. forces from that country. The percentage of 2021 cases of malaria caused by Plasmodium falciparum (55.0%; n=11) was the highest of any year of the surveillance period; however, the number of cases was the third lowest observed during the surveillance period. The number of malaria cases caused by Plasmodium vivax in 2021 (n=1) was the lowest observed during the surveillance period. The remaining 8 malaria cases were labeled as associated with other/unspecified types of malaria (40.0%). Malaria was diagnosed at or reported from 15 different medical facilities in the U.S.; only 2 were reported outside of the U.S., 1 each in Germany and Africa. Providers of medical care to military members should be knowledgeable of and vigilant for clinical manifestations of malaria outside of endemic areas.

Effects of opium inhalation on physical and biochemical parameters of stray dogs in Kabul city, Afghanistan

Abstract Background: Afghanistan is one of the biggest opium producing country in the world. There are more than a million drug addicts in the country, which most of them are living in public places. Stray dogs who lives with drug addicts are at highest risk of inhaling drugs Aim: Aim of this study is to evaluate changes in physical and biochemical parameters of stray dogs inhaling drugs. Methods: Total of 12 dogs were assigned into two groups of healthy and infected (stray dogs who inhale drugs) dogs. Physical and biochemical parameters of both groups were evaluated. Results: Subjective evaluation showed clinical changes such as congestion of conjunctiva in infected group. Biochemical examination showed significantly higher level of glucose (P<0.05) and total protein (P<0.01) in infected group compared to healthy group. The ratio of other biochemical parameters was slightly decreased as compare to healthy dogs. Conclusion: Drug inhalation can alter biochemical parameters like glucose and total protein in dogs. Keywords: Addicts, Biochemical parameters, Opium, Physical parameters, Stray dogs

Cost-effectiveness of point-of-care C-Reactive Protein test compared to current clinical practice as an intervention to improve antibiotic prescription in malaria-negative patients in Afghanistan

BACKGROUND

Antimicrobial resistance (AMR) is a global health problem requiring a reduction in inappropriate antibiotic prescribing. Point-of-Care C-Reactive Protein (POCCRP) tests could distinguish between bacterial and non-bacterial causes of fever in malaria-negative patients and thus reduce inappropriate antibiotic prescribing. However, the cost-effectiveness of POCCRP testing is unclear in low-income settings.

METHODS

A decision tree model was used to estimate cost-effectiveness of POCCRP versus current clinical practice at primary healthcare facilities in Afghanistan. Data were analysed from healthcare delivery and societal perspectives. Costs were reported in 2019 USD. Effectiveness was measured as correctly treated febrile malaria-negative patient. Cost, effectiveness and diagnostic accuracy parameters were obtained from primary data from a cost-effectiveness study on malaria rapid diagnostic tests in Afghanistan and supplemented with POCCRP-specific data sourced from the literature. Incremental cost-effectiveness ratios (ICERs) reported the additional cost per additional correctly treated febrile malaria-negative patient over a 28-day time horizon. Univariate and probabilistic sensitivity analyses examined the impact of uncertainty of parameter inputs. Scenario analysis included economic cost of AMR per antibiotic prescription.

RESULTS

The model predicts that POCCRP intervention would result in 137 fewer antibiotic prescriptions (6%) with a 12% reduction (279 prescriptions) in inappropriate prescriptions compared to current clinical practice. ICERs were $14.33 (healthcare delivery), $11.40 (societal), and $9.78 (scenario analysis) per additional correctly treated case.

CONCLUSIONS

POCCRP tests could improve antibiotic prescribing among malaria-negative patients in Afghanistan. Cost-effectiveness depends in part on willingness to pay for reductions in inappropriate antibiotic prescribing that will only have modest impact on immediate clinical outcomes but may have long-term benefits in reducing overuse of antibiotics. A reduction in the overuse of antibiotics is needed and POCCRP tests may add to other interventions in achieving this aim. Assessment of willingness to pay among policy makers and donors and undertaking operational trials will help determine cost-effectiveness and assist decision making.

Modelling the spread of serotype-2 vaccine derived-poliovirus outbreak in Pakistan and Afghanistan to inform outbreak control strategies in the context of the COVID-19 pandemic

Background

Since July 2019, Pakistan and Afghanistan have been facing an outbreak of serotype-2 circulating vaccine derived poliovirus (cVDPV2) in addition to continued transmission of serotype-1 wild poliovirus (WPV1) and SARS-CoV-2 in 2020. Understanding the risks of cVDPV2 transmission due to pause of global vaccination efforts and the impact of potential vaccination response strategies in the current context of COVID-19 mitigation measures is critical.

Methods

We developed a stochastic, geographically structured mathematical model of cVDPV2 transmission which captures both mucosal and humoral immunity separately and allows for reversion of serotype-2 oral polio vaccine (OPV2) virus to cVDPV2 following vaccine administration. The model includes geographic heterogeneities in vaccination coverage, population immunity and population movement. The model was fitted to historic cVDPV2 cases in Pakistan and Afghanistan between January 2010-April 2016 and July 2019-March 2020 using iterated particle filtering. The model was used to simulate spread of cVDPV2 infection from July 2019 to explore impact of various proposed vaccination responses on stopping transmission and risk of spread of reverted Sabin-2 under varying assumptions of impacts from COVID-19 lockdown measures on movement patterns as well as declines in vaccination coverage.

Results

Simulated monthly incidence of cVDPV2 from the best-fit model demonstrated general spatio-temporal alignment with observed cVDPV2 cases. The model predicted substantial spread of cVDPV2 infection, with widespread transmission through 2020 in the absence of any vaccination activities. Vaccination responses were predicted to substantially reduce transmission and case burden, with a greater impact from earlier responses and those with larger geographic scope. While the greatest risk of seeding reverted Sabin-2 was predicted in areas targeted with OPV2, subsequent spread was greatest in areas with no or delayed response. The proposed vaccination strategy demonstrated ability to stop the cVDPV2 outbreak (with low risk of reverted Sabin-2 spread) by February 2021.

Conclusion

Outbreak response vaccination campaigns against cVDPV2 will be challenging throughout the COVID-19 pandemic but must be implemented urgently when feasible to stop transmission of cVDPV2.

Characteristics of burn casualties treated at role 2 in Afghanistan

BACKGROUND

Role 2 medical treatment facilities (MTFs) are frequently located in austere settings and have limited resources. A dedicated assessment of burn casualties treated at this level of care has not been performed. Therefore, the objective of this study was to characterize burn casualties presenting to role 2 MTFs in Afghanistan, along with the procedures they required, complications, and mortality to begin understanding the resources consumed by their care.

METHODS

We identified burn casualties from the Department of Defense Trauma Registry (DODTR). The inclusion criteria were (1) experienced burn injuries in Afghanistan between October 2005 and April 2018 and (2) had documentation of treatment at role 2 in the DODTR. We excluded casualties with only first-degree burns, not otherwise specified burns, or only corneal burns. Casualty demographics, injury characteristics, procedures, and outcomes were reported.

RESULTS

We identified 453 burn casualties with a median (interquartile range) Injury Severity Score of 10 (4-22) and percent total body surface area burned of 11 (5-30). There were 123 casualties (27.2%) with inhalation injury, and the casualties experienced 3,343 additional traumatic injuries and needed 2,530 procedures. Casualties with documentation of resuscitation information received a median (interquartile range) of 1.9 (0.7-3.7) L of crystalloid fluids. Complications were documented in 53 casualties (11.7%). Final mortality was reported in 36 casualties (8.0%), and mortality at role 2 MTFs was reported in 7 casualties (1.5%).

CONCLUSION

Burn casualties had many injuries and needed many procedures, including those related to airway management, resuscitation, and wound care. Given the urgency of these procedures, ensuring that there is enough equipment and supplies will be important in the future. Although infrequent, some casualties experienced complications. Factors that may influence resuscitation include injury severity, concomitant traumatic injuries, and available supplies. Obtaining more contextual information on the patient care environment will be useful going forward.

Variant Analysis of SARS-CoV-2 Genomes from Belgian Military Personnel Engaged in Overseas Missions and Operations

More than a year after the first identification of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as the causative agent of the 2019 coronavirus disease (COVID-19) in China, the emergence and spread of genomic variants of this virus through travel raise concerns regarding the introduction of lineages in previously unaffected regions, requiring adequate containment strategies. Concomitantly, such introductions fuel worries about a possible increase in transmissibility and disease severity, as well as a possible decrease in vaccine efficacy. Military personnel are frequently deployed on missions around the world. As part of a COVID-19 risk mitigation strategy, Belgian Armed Forces that engaged in missions and operations abroad were screened (7683 RT-qPCR tests), pre- and post-mission, for the presence of SARS-CoV-2, including the identification of viral lineages. Nine distinct viral genotypes were identified in soldiers returning from operations in Niger, the Democratic Republic of the Congo, Afghanistan, and Mali. The SARS-CoV-2 variants belonged to major clades 19B, 20A, and 20B (Nextstrain nomenclature), and included "variant of interest" B.1.525, "variant under monitoring" A.27, as well as lineages B.1.214, B.1, B.1.1.254, and A (pangolin nomenclature), some of which are internationally monitored due to the specific mutations they harbor. Through contact tracing and phylogenetic analysis, we show that isolation and testing policies implemented by the Belgian military command appear to have been successful in containing the influx and transmission of these distinct SARS-CoV-2 variants into military and civilian populations.

Prehospital Intervention Analysis of Helicopter Crashes in Afghanistan

BACKGROUND

Based on isolated case reports, military helicopter mishaps often result in multiple critical casualties leading to complicated stabilization and evacuation by healthcare providers. The aim of this retrospective descriptive analysis is to describe the incidence of common prehospital injuries associated with rotary wing crashes in order to improve mission planning and casualty survivability.

METHODS

This is a secondary analysis of data from the Prehospital Trauma Registry and the Department of Defense Trauma Registry (DoDTR) from April 2003 through May 2019. We searched within our dataset for all encounters involving aviation crashes.

RESULTS

From April 2003 through May 2019 there were 1,357 casualty encounters in the Prehospital Trauma Registry. There were 12 casualties identified injured by aircraft crash, of which, 10 were linkable to the DoDTR for outcome data. All encounters for this sub analysis occurred in Afghanistan in 2014, all were US military service members, and a majority were enlisted conventional forces. Most prehospital interventions focused on hemorrhage control, to include limb tourniquets (n=3), pressure dressings (n=2), and pelvic splint (n=1). One patient received a cervical collar and two patients received temperature control with a hypothermia kit.

CONCLUSIONS

In this case series, hemorrhage control and extremity stabilization accounted for the majority of prehospital interventions. Larger datasets are needed to validate findings and extrapolate it into mission planning.

Underweight and overweight/obesity among adults in Afghanistan: prevalence and correlates from a national survey in 2018

BACKGROUND

The study aimed to estimate the prevalence and correlates of underweight and overweight/obesity among adults in Afghanistan.

METHODS

National cross-sectional survey data of 3779 persons aged 18-69 years were analysed. Multinomial logistic regression was used to estimate factors associated with underweight and overweight/obesity relative to normal weight.

RESULTS

In all, 7.8% of the study sample was underweight (BMI < 18.5 kg/m²), 49.5% had normal weight (BMI 18.5-24.9 kg/m²), 25.5% overweight (25.0-29.9 kg/m²), and 17.2% obesity. In adjusted multinomial logistic regression, factors negatively associated with underweight were male sex (adjusted relative risk ratio (ARRR): 0.30, 95% confidence interval (CI): 0.15-0.58) and hypertension (ARRR: 0.51, 95% CI: 0.27-0.95) and factors positively associated with underweight were sedentary behaviour (ARRR: 1.85, 95% CI: 1.11-3.10) and current tobacco use (ARRR: 2.58, 95% CI: 1.08-6.16). Factors positively associated with overweight/obesity were aged 30-44 years (ARRR: 2.00, CI: 1.51-2.66) and aged 45-69 years (ARRR: 1.58, CI: 1.09-2.31) (compared to 18-29 years) (ARRR: 1.28, CI: 1.14-2.18), hypertension (ARRR: 2.74, CI: 1.89-3.96), and type 2 diabetes (ARRR: 1.82, CI: 1.13-2.94), and high physical activity (ARRR: 0.70, CI: 0.50-0.98) was negatively associated with overweight/obesity.

CONCLUSION

Almost one in ten adult respondents were underweight and more than two in five were overweight/obese, confirming a dual burden of malnutrition in Afghanistan.

Prevalence of latent tuberculosis infection among health workers in Afghanistan: A cross-sectional study

BACKGROUND

About 26% of the world's population may have latent tuberculosis infection (LTBI). Health care workers are a high-risk category because of their professional exposure.

METHODS

This cross-sectional study assessed the LTBI burden among health care workers in Afghanistan, a high-TB-burden country. We selected health facilities using a systematic sampling technique and invited all workers at the targeted health facilities to participate. Participants were interviewed about sociodemographic and exposure variables and received tuberculin skin tests for LTBI.

RESULTS

Of the 4,648 health care workers invited to participate, 3,686 had tuberculin skin tests. The prevalence of LTBI was found to be 47.2% (1,738 workers). Multivariate analysis showed that a body mass index of ≥ 30 and marriage were associated with an increased risk of LTBI. Underweight (body mass index of ≤ 18 and below) and normal body mass index had no association with increased risk of LTBI.

CONCLUSION

LTBI is high among health care workers in Afghanistan. We recommend instituting infection control measures in health facilities and screening workers for timely TB diagnosis.

Gender-Specific Prevalence of Risk Factors for Non-Communicable Diseases by Health Service Use among Schoolteachers in Afghanistan

Objectives of this study were: (1) to examine gender differences in biomedical indicators, lifestyle behaviors, self-health check practices, receipt of professional non-communicable disease (NCD)-related lifestyle advice, and the use of health services among teachers in Afghanistan; and (2) to seek the patterns of these indicators among users and non-users of health services among both male and female teachers. This cross-sectional study was carried out among 600 schoolteachers in Kabul city in February 2017. Gender differences in percentage distributions of abnormal biomedical indicators, lifestyle behaviors, self-health check practices, and receipt of professional lifestyle advice were examined. These patterns were further analyzed according to the use of health services in the previous 12 months by both genders. The results showed that male teachers had a higher prevalence of hypertension, increased serum triglycerides, physically active lifestyle, and tobacco use than female teachers (28.2/20.4, p = 0.038; 47.0/37.9, p = 0.040; 54.3/40.9, p = 0.002; 15.8/0.7, p < 0.001, respectively); female teachers had a higher prevalence of increased serum LDL cholesterol, overweight/obesity, and frequent consumption of fruits/vegetables than male teachers (61.3/50.8, p = 0.018; 64.7/43.5, p < 0.001; 71.4/53.8, p < 0.001, respectively). Female teachers were more likely to receive professional lifestyle advice related to NCDs than male teachers. Although users of health services practiced self-health checks and received professional lifestyle advice more frequently than non-users, abnormal biomedical indicators were similarly shown among users and non-users of health services in both genders. In conclusion, high prevalence of abnormal biomedical indicators was indicated in both male and female teachers, although the specific abnormal biomedical indicators differed by gender. Users and non-users of health services presented a similar prevalence of these abnormal indicators. Understanding the differences in patterns of NCD risk factors is essential when developing gender-informed policies.

The prevalence of diabetes in Afghanistan: a systematic review and meta-analysis

BACKGROUND

The aim of this paper is to investigate the prevalence of diabetes and its associated risk factors in Afghanistan through a systematic review and meta-analysis.

METHODS

A comprehensive literature search was conducted using EMBASE, PubMed, Web of Sciences, Google Scholar and the Cochrane library, carried out from inception to April 312,020, without language restriction. Meta-analysis was performed using DerSimonian and Laird random-effects models with inverse variance weighting. The existence of publication bias was initially assessed by visual inspection of a funnel plot and then tested by the Egger regression test. Subgroup analyses and meta-regression were used to explore potential sources of heterogeneity. This systematic review was reported by following the PRISMA guidelines and the methodological quality of each included study was evaluated using the STROBE guidelines.

RESULTS

Out of 64 potentially relevant studies, only 06 studies fulfilled the inclusion criteria and were considered for meta-analysis. The pooled prevalence of diabetes in the general population based on population-based studies were 12.13% (95% CI: 8.86-16.24%), based on a pooled sample of 7071 individuals. Results of univariate meta-regression analysis revealed that the prevalence of diabetes increased with mean age, hypertension and obesity. There was no significant association between sex (male vs female), smoking, the methodological quality of included articles or education (illiterate vs literate) and the prevalence of diabetes.

CONCLUSIONS

This meta-analysis reports the 12.13% prevalence of diabetes in Afghanistan,with the highest prevalence in Kandahar and the lowest in Balkh province. The main risk factors include increasing age, obesity and hypertension. Community-based care and preventive training programmes are recommended.

Updated characterization of poliovirus transmission in Pakistan and Afghanistan and the impacts of different outbreak response vaccine options

Background

Pakistan and Afghanistan remain the only reservoirs of wild poliovirus transmission. Prior modeling suggested that before the COVID-19 pandemic, plans to stop the transmission of serotype 1 wild poliovirus (WPV1) and persistent serotype 2 circulating vaccine-derived poliovirus (cVDPV2) did not appear on track to succeed.

Methods

We updated an existing poliovirus transmission and Sabin-strain oral poliovirus vaccine (OPV) evolution model for Pakistan and Afghanistan to characterize the impacts of immunization disruptions and restrictions on human interactions (i.e., population mixing) due to the COVID-19 pandemic. We also consider different options for responding to outbreaks and for preventive supplementary immunization activities (SIAs).

Results

The modeling suggests that with some resumption of activities in the fall of 2020 to respond to cVDPV2 outbreaks and full resumption on January 1, 2021 of all polio immunization activities to pre-COVID-19 levels, Pakistan and Afghanistan would remain off-track for stopping all transmission through 2023 without improvements in quality.

Conclusions

Using trivalent OPV (tOPV) for SIAs instead of serotype 2 monovalent OPV (mOPV2) offers substantial benefits for ending the transmission of both WPV1 and cVDPV2, because tOPV increases population immunity for both serotypes 1 and 2 while requiring fewer SIA rounds, when effectively delivered in transmission areas.

Pharmacological management of South Asians with type 2 diabetes: Consensus recommendations from the South Asian Health Foundation

South Asians constitute approximately 1.6 billion people from the Indian subcontinent, comprising Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka; and make up the largest diaspora globally. Compared to the White European population, this group is at a higher risk of developing type 2 diabetes along with cardiovascular, renal and eye complications. Over the recent years, a number of new therapies for type 2 diabetes have become available for which cardiovascular outcome trials (CVOTs) have been published. The recent ADA/EASD consensus guidelines on diabetes, pre-diabetes and cardiovascular diseases' offer a transitional shift in type 2 diabetes management. The new consensus recommendations are based on recent CVOTs, many of which had a representation of South Asian cohorts. In light of this new evidence, there is urgent need for an integrated, evidence-based, cost-effective and individualised approach specific for South Asians. This review takes into consideration the evidence from these CVOTs and provides best practice recommendations for optimal management of South Asian people with type 2 diabetes, alongside the previously published consensus report from South Asian Health Foundation in 2014 [1].

AB569, a non-toxic combination of acidified nitrite and EDTA, is effective at killing the notorious Iraq/Afghanistan combat wound pathogens, multi-drug resistant Acinetobacter baumannii and Acinetobacter spp

Multi-drug resistant (MDR) Acinetobacter baumannii (Ab) and Acinetobacter spp. present monumental global health challenges. These organisms represent model Gram-negative pathogens with known antibiotic resistance and biofilm-forming properties. Herein, a novel, nontoxic biocide, AB569, consisting of acidified nitrite (A-NO₂^-) and ethylenediaminetetraacetic acid (EDTA), demonstrated bactericidal activity against all Ab and Acinetobacter spp. strains, respectively. Average fractional inhibitory concentrations (FICs) of 0.25 mM EDTA plus 4 mM A-NO₂^- were observed across several clinical reference and multiple combat wound isolates from the Iraq/Afghanistan wars. Importantly, toxicity testing on human dermal fibroblasts (HDFa) revealed an upper toxicity limit of 3 mM EDTA plus 64 mM A-NO₂^-, and thus are in the therapeutic range for effective Ab and Acinetobacter spp. treatment. Following treatment of Ab strain ATCC 19606 with AB569, quantitative PCR analysis of selected genes products to be responsive to AB569 revealed up-regulation of iron regulated genes involved in siderophore production, siderophore biosynthesis non-ribosomal peptide synthetase module (SBNRPSM), and siderophore biosynthesis protein monooxygenase (SBPM) when compared to untreated organisms. Taken together, treating Ab infections with AB569 at inhibitory concentrations reveals the potential clinical application of preventing Ab from gaining an early growth advantage during infection followed by extensive bactericidal activity upon subsequent exposures.

Insights From Modeling Preventive Supplemental Immunization Activities as a Strategy to Eliminate Wild Poliovirus Transmission in Pakistan and Afghanistan

Many countries use supplemental immunization activities (SIAs) with oral poliovirus vaccine (OPV) to keep their population immunity to transmission high using preventive, planned SIAs (pSIAs) and outbreaks response SIAs (oSIAs). Prior studies suggested that investment in pSIAs saved substantial health and financial costs due to avoided outbreaks. However, questions remain about the benefits of SIAs, particularly with the recent introduction of inactivated poliovirus vaccine (IPV) into routine immunization in all OPV-using countries. The mounting costs of polio eradication activities and the need to respond to oSIAs threatens the use of limited financial resources for pSIAs, including in the remaining countries with endemic transmission of serotype 1 wild poliovirus (WPV1) (i.e., Pakistan and Afghanistan). A recent updated global poliovirus transmission model suggested that the Global Polio Eradication Initiative (GPEI) is not on track to stop transmission of WPV1 in Pakistan and Afghanistan. We use the updated global model to explore the role of pSIAs to achieve WPV1 eradication. We find that unless Pakistan and Afghanistan manage to increase the quality of bivalent OPV (bOPV) pSIAs, which we model as intensity (i.e., sufficiently high-coverage bOPV pSIAs that reach missed children), the model does not lead to successful eradication of WPV1. Achieving WPV1 eradication, the global objectives of the GPEI, and a successful polio endgame depend on effective and sufficient use of OPV. IPV use plays a negligible role in stopping transmission in Pakistan and Afghanistan and most other countries supported by the GPEI, and more IPV use will not help to stop transmission.

The Comparison of Real-time-PCR-HRM and Microscopy Methods for Detection of Mixed Plasmodium spp. Infections in Laghman Province, Afghanistan

BACKGROUND

Laghman province, in the east of Afghanistan, is one of the most malaria endemic regions with prominence of Plasmodium vivax and Plasmodium falciparum. So far, no study has been conducted to investigate the extent of mixed infections in this area.

OBJECTIVE

In this study, we aimed to evaluate the prevalence of mixed infections of malaria in Laghman province by using a new and highly sensitive molecular method (real-time polymerase chain reaction high resolution melting analysis) and compare its results with microscopically confirmed cases of malaria.

METHODS

In general, 347 infected individuals have been referred to Khalwati laboratory that is located in the center of Laghman province from May to November of 2018. Microscopic analysis was performed on prepared thick and thin blood films under ×100 lens with oil immersion. The real- time-PCR-HRM assay was performed using an ABI 7500 Fast Real-time PCR system.

RESULTS

In a microscopic examination, out of 347 patients referred to the Center, 267 (76.94%) cases were detected to be Plasmodium vivax, 79 (22.76%) Plasmodium falciparum and 1 (0.28%) case of mixed of two species. However, by using Real-time PCR-HRM technique, 249 (71.75%) were detected Plasmodium vivax, 79 (22.76%) were Plasmodium falciparum and 19 (5.47%) were mixed of two species.

CONCLUSION

Our result indicated that the Real-time PCR-HRM method is more accurate and more reliable than microscopic method in the diagnosis of malaria mixed infections.

Peer victimization and experiences of violence at school and at home among school age children with disabilities in Pakistan and Afghanistan

Background: Children with disabilities are more likely to experience violence or injury at school and at home, but there is little evidence from Central Asia. Objective: To describe the prevalence of disability and associations with peer violence perpetration and victimization, depression, corporal punishment, school performance and school attendance, among middle school children in Pakistan and Afghanistan. Method: This is a secondary analysis of data gathered in the course of evaluations of interventions to prevent peer violence conducted in Pakistan and Afghanistan as part of the 'What Works to Prevent Violence against Women and Girls Global Programme'. In Pakistan, the research was conducted in 40 schools, and disability was assessed at midline in 1516 interviews with Grade 7s. In Afghanistan, the data were from the baseline study conducted in 11 schools with 770 children. Generalized Linear Mixed Modeling was used to assess associations with disability. Results: In Afghanistan, the prevalence of disability was much higher for girls (22.1%) than boys (12.9%), while in Pakistan 6.0% of boys and girls reported a disability. Peer violence victimization was strongly associated with disability in Afghanistan and marginally associated in Pakistan. In Pakistan, perpetration of peer violence was associated with disability. In both countries, disability was significantly associated with higher depression scores. Food insecurity was strongly associated with disability in Afghanistan. Conclusion: Disability is highly prevalent in Afghanistan and Pakistan schools and this is associated with a greater risk of experiencing and perpetrating peer violence. It is important to ensure that all children can benefit from school-based prevention interventions.

Conflict, community, and collaboration: shared implementation barriers and strategies in two polio endemic countries

BACKGROUND

Afghanistan and Nigeria are two of the three remaining polio endemic countries. While these two countries have unique sociocultural characteristics, they share major polio risk factors. This paper describes the countries' shared contexts and highlights important lessons on implementing polio eradication activities among hard-to-reach populations relevant for future global health programs.

METHODS

A grey literature review of the Global Polio Eradication Initiative (GPEI) followed by an online survey was conducted in both countries. The survey was targeted to individuals who have been involved continuously in polio eradication activities for 12 months or more since 1988. A sub-set of respondents from the survey was recruited for key-informant interviews (KII). The survey and KIIs were conducted between September 2018-April 2019. A cross-case comparison analysis was conducted to describe shared implementation challenges, strategies, and unintended consequences of polio eradication activities across these contexts.

RESULTS

Five hundred thirteen and nine hundred twenty-one surveys were completed in Afghanistan and Nigeria respectively; 28 KIIs were conducted in Afghanistan and 29 in Nigeria. Major polio eradication activities in both countries include house-to-house campaigns, cross-border stations, outreach to mobile populations, and surveillance. Common barriers to these activities in both countries include civil unrest and conflict; competing political agendas; and vaccine refusal, fatigue, and mistrust, all of which are all bases for describing hard-to-reach populations. Both countries employed strategies to engage community leadership, political and religious groups through advocacy visits, and recruited community members to participate in program activities to address misconceptions and distrust. Recruitment of female workers has been necessary for accessing women and children in conservative communities. Synergy with other health programs has been valuable; health workers have improved knowledge of the communities they serve which is applicable to other initiatives.

CONCLUSIONS

The power of community engagement at all levels (from leadership to membership) cannot be overstated, particularly in countries facing civil unrest and insecurity. Workforce motivation, community fatigue and mistrust, political priorities, and conflict are intricately interrelated. Community needs should be holistically assessed and addressed;programs must invest in the needs of health workers who engage in these long-term health programs, particularly in unsafe areas, to alleviate demotivation and fatigue.

Crimean-Congo Hemorrhagic Fever (CCHF) in Afghanistan: A retrospective single center study

BACKGROUND

Crimean-Congo Hemorrhagic Fever (CCHF) is a particular regional concern because of endemicity in Afghanistan and many neighboring countries. The prevalence of CCHF has been increasing in this region. These concerns are compounded because there is no vaccine or therapeutic for CCHF and Afghanistan lacks adequate public health infrastructure in preventing, detecting, and containing cases. This investigation aimed to study the epidemiological, clinical, and laboratory features of CCHF in Afghanistan that might be useful in prevention and case detection, particularly in a limited resource setting.

METHOD

A descriptive and analytic retrospective study of epidemiological, clinical, and laboratory features of confirmed patients (enzyme-linked immunosorbent assay (ELISA)-positive for CCHF) who were admitted to referral infectious center of Afghanistan from March 2017, to December 2018, was carried out.

RESULTS

There were 51 ELISA-confirmed CCHF patients, comprised of 14 females and 37 males. The mean age was 30 years of age, and there were 11 deaths. The case fatality rate (CFR) was 21.6% and was not significant between sexes (p = 0.8). Most cases were recorded from June to September, which is the period containing Eid-al-Adha. With regard to occupation, 13.7% and 11.8% of subjects were butchers and shepherds, respectively. The leading clinical manifestations were fever, hemorrhage, and myalgia. The mean time between onset of symptoms and admission to the hospital was 4.9 days in recovered cases and 4.7 days for expired cases.

CONCLUSION

The prevalence of CCHF is increasing in Afghanistan. The majority of cases visited the hospital during the late phase of infection. This delay can negatively affect the efficacy of treatment and lead to severe health outcomes. Our findings reveal that impaired Alanine aminotransferase (ALT), hemorrhagic manifestations (including epistaxis), and impaired consciousness were factors associated with a higher mortality rate. These biomarkers may provide a clue to possible early effective interventions and increasing the chance of survival of the patients.

War surgery in Afghanistan: a model for mass causalities in terror attacks?

PURPOSE

The aim of the study was to identify solution strategies from a non-governmental (NGO) hospital in a war region for violence-related injuries and to show how high-income countries (HIC) might benefit from this expertise.

METHODS

NGO trauma hospital in Lashkar Gah, Afghanistan. Four hundred eighty-four war victims admitted in a three month period (February 2016-May 2016) were included. Patients´ characteristics were analyzed.

RESULTS

The mean age was 23.5 years. Four hundred thirty-four (89.9%) were male, and 50 (10.1%) were female. The most common cause of injury was bullet injuries, shell injuries, and mine injuries. The most common injured body region was the lower extremity, upper extremity, and the chest or the face. Apart from surgical wound care and debridements, which were performed on every wound in the operation theatre, laparotomy was the most common surgical procedure, followed by installation of a chest drainage and amputation.

CONCLUSION

The surgical expertise and clear pathways outweigh modern infrastructure. In case of a mass casualty incident, fast decision-making with basic diagnostic means in order to take rapid measurements for life-saving therapies could make the difference.

Prehospital Combat Wound Medication Pack Administration in Iraq and Afghanistan: A Department of Defense Trauma Registry Analysis

BACKGROUND

The United States (US) military utilizes combat wound medication packs (CWMP) to provide analgesia and wound prophylaxis in casualties who are still able to fight. We compared characteristics of combat casualties receiving CWMP to those not receiving CWMP. We also describe the proportions of casualties with injury patterns consistent with Tactical Combat Casualty Care (TCCC) guideline indications for CWMP use who received this intervention.

METHODS

This is a secondary analysis of Department of a Defense Trauma Registry (DODTR) dataset of US military personnel from January 2007 to August 2016. We searched for all subjects with documented use of at least one medication from the CWMP (acetaminophen, meloxicam, moxifloxacin).

RESULTS

Within our dataset, 11,665 casualties were US military Servicemembers. Overall, <1% (84) of our study population received the CWMP. The median age and mechanism of injuries were similar between CWMP nonrecipients versus recipients. Median composite injury scores were higher for nonrecipients than recipients (6 versus 4, P < .001). Proportions of casualties with injury patterns meeting TCCC guideline CWMP indications who received this intervention were low: gunshot wound, <1% (14 of 1805), tourniquet applied, <1% (11 of 1912), major amputation, <1% (5 of 803), and open fracture, <1% (10 of 2425). Based on serious injuries by body region, we had similar findings for the thorax (<1%; 3 of 1122), abdomen (<1%; 1 of 736), and extremities (<1%; 11 of 2699).

CONCLUSIONS

Subjects receiving the CWMP were less severely injured compared to those who did not receive this intervention. The CWMP had very infrequent use among those casualties with injury patterns meeting indications specified in the TCCC Guidelines for use of this intervention.

Results of Radiological and Serological Screenings in Individuals Sharing the Same Living Area as Patients with Hydatid Cyst in Afghanistan's State Hospital

OBJECTIVE

To determine the results of radiological and serological screenings in individuals who shared the same living space as patients with hydatid cyst in a State Hospital of Afghanistan.

METHODS

Patients presenting with hydatid cyst to a public hospital in Afghanistan were included in this study. Full sampling method was used. Also, the relatives of the patients were called to the hospital and investigated for the presence of hydatid cyst antibodies through direct chest X-ray, upper abdominal ultrasonography and ELISA.

RESULTS

During the study period, a total of 214 patients, including 102 male and 112 female, underwent radiological and serological screenings. While cysts were radiologically detected in the liver, lung and spleen in 8, 2 and 1 patient, respectively, the serology was positive in 22 patients.

CONCLUSION

As a result of the study, it was concluded that the patients who shared the same environment as the patients who were diagnosed with hydatid cyst in an endemic region for cyst hydatid disease.

Age distribution and types of breast lesions among Afghan women diagnosed by fine needle aspiration cytology (FNAC) at a tertiary care centre in Afghanistan: a descriptive cross-sectional study

OBJECTIVES

In Afghanistan, breast diseases are a common reason for women to visit hospitals. This is the first study in Afghanistan aimed to describe the age distribution and types of breast diseases among patients diagnosed by fine needle aspiration cytology.

DESIGN

Descriptive cross-sectional study.

SETTING

French Medical Institute for Mothers and Children, Kabul, Afghanistan.

PARTICIPANTS

The study included 650 patients with breast lesions between 1 April 2015 and 1 April 2019.

RESULTS

The mean age of diagnosis was 35.38 (SD ±13.11) years, ranging from 15 to 75 years. The most common diagnosis was cancer (24% of all cases). The second most common diagnosed lesion was fibroadenoma, constituting 22.4%, and the third most common lesion was fibrocystic changes, with 15.4% of cases. Inflammatory conditions were diagnosed in 9.7% of cases, granulomatous inflammation in 9.1%, lesions only suspicious for malignancy in 5.5%, lipoma in 2.8% and miscellaneous benign lesions in 11.1%. Cancer was diagnosed at the youngest age of 20 years. Cancer was more common on the left side (62%), and only one case (0.9%) was bilateral.

CONCLUSION

Our study showed that cancer was the most commonly diagnosed lesion and was reported at younger ages too. This suggests that physicians should not ignore any breast lump in younger patients and that the possibility of cancer must be considered. Further country-wide studies are suggested to assess breast cancer and associated risk factors.

Translating drug resistant tuberculosis treatment guidelines to reality in war-torn Kandahar, Afghanistan: A retrospective cohort study

INTRODUCTION

Afghanistan is affected by one of the world's longest protracted armed conflicts, frequent natural disasters, disease outbreaks and large population movements and it suffers from a high burden of tuberculosis (TB), including rifampicin-resistant TB (RR-TB). The study shows Médecins Sans Frontières' experiences with care for patients with RR-TB in Kandahar Province. We describe the uptake of RR-TB treatment, how World Health Organisation criteria for the choice between the short and an individualized regimen were implemented, and treatment outcomes.

METHODS

This is a retrospective cohort analysis of routinely collected data from RR-TB patients enrolled in care from 2016 until 2019. Descriptive analysis was performed to present characteristics of patients and treatment outcomes. Multivariable Cox analysis was performed to identify risk factors for having an unfavourable treatment outcome.

RESULTS

Out of 146 enrolled RR-TB patients, 112 (76.7%) started treatment: 41 (36.6%) and 71 (63.4%) with the short and individualized treatment regimen, respectively. Of 82 with results for fluoroquinolone susceptibility, 39 (47.6%) had fluoroquinolone-resistant TB. Seven patients with initially fluoroquinolone-resistant TB and three pregnant women started the short regimen and 18 patients eligible for the short regimen started the injectable-free individualized regimen. Overall, six-month smear and culture conversion were 98.7% and 97.1%, respectively; treatment success was 70.1%. Known initial fluoroquinolone resistance (aHR 3.77, 95%CI:1.53-9.27) but not choice of regimen predicted having an unfavourable outcome.

CONCLUSION

Even though criteria for the choice of treatment regimen were not applied strictly, we have achieved acceptable outcomes in this cohort. To expand RR-TB care, treatment regimens should fit provision at primary health care level and take patient preferences into account.

Prevalence, related factors and maternal outcomes of primary postpartum haemorrhage in governmental hospitals in Kabul-Afghanistan

BACKGROUND

To determine the prevalence, related factors and maternal outcomes of primary PPH in governmental hospitals in Kabul Afghanistan.

METHODS

An observational study was designed to determine the prevalence, related factors and maternal outcomes of primary PPH in governmental hospitals in Kabul-Afghanistan. The population of this study consisted of all women who gave birth to a child between August and October 2018. The structured checklist was used to collect the data from patients who were suffering from primary PPH.

RESULTS

Among the 8652 women who were observed, 215 (2.5%) of them suffered from primary PPH and 2 (0.9%) of them died under caesarean section. The most common related factors of primary PPH were uterine atonia (65.6%), previous PPH (34.9%), prolonged labor (27%), genital tract trauma (26.5%), and induction of labor (20.5%). The most common maternal outcomes of primary PPH were respiratory failure (7%), hysterectomy (6%), and hypovolaemic shock (5.1%).

CONCLUSIONS

According to our findings, the major cause of postpartum bleeding was uterine atonia. Therefore, postpartum care of women is essential, especially for those with previous PPH and prolonged labor that require more attention.

The impacts of combined social and economic empowerment training on intimate partner violence, depression, gender norms and livelihoods among women: an individually randomised controlled trial and qualitative study in Afghanistan

Introduction

We assessed whether the Women for Women International (WfWI) economic and social empowerment programme could reduce women's experiences of intimate partner violence (IPV) and depression in Afghanistan.

Methods

We conducted a two-arm individually randomised controlled trial in six urban and peri-urban communities. Communities were selected by WfWI for being conflict affected and showing signs of economic vulnerability (eg, little or no education, living in extreme poverty). Individual eligibility were female, aged 18-49, able to consent to participate and one woman per household. At 22 months, three primary outcomes were assessed: past year physical IPV experience; past year severe IPV experience; depressive symptoms. There was no blinding to arms. We conducted an intention-to-treat analysis, controlling for age. We also conducted qualitative interviews at endline, analysed using thematic analysis.

Results

1461 women (n=933 married) were recruited and randomised. Retention at endline was n=1210 (82%). Primary outcomes were in the hypothesised direction, but showed no significant impacts: physical IPV (adjusted OR (aOR) 0.88 (0.62 to 1.23)), severe IPV (aOR 0.75 (0.50 to 1.11)) and depressive symptoms (β -0.35 (-1.19 to 0.48)). Women reported reduced food insecurity (β -0.48 (-0.85 to -0.12)), higher earnings (β 3.79 (0.96 to 6.61)) and savings (β 11.79 (9.95 to 13.64)). Women reported less gender-inequitable attitudes (β -0.89 (-1.15 to -0.62)), more household decision-making (β 0.35 (-0.04 to 0.74)) and increased mobility (aOR 1.78 (1.27 to 2.50)). Twenty-eight in-depth interviews were conducted.

Conclusion

The intervention did not impact IPV or depression. The intervention did improve livelihoods, create more gender-equitable relationships and increase women's mobility. Translating these gains into IPV and depression reduction is critical.

Potential health impact and cost-effectiveness of bivalent human papillomavirus (HPV) vaccination in Afghanistan

INTRODUCTION

Human papillomavirus (HPV) vaccination has not been introduced in many countries in South-Central Asia, including Afghanistan, despite the sub-region having the highest incidence rate of cervical cancer in Asia. This study estimates the potential health impact and cost-effectiveness of HPV vaccination in Afghanistan to inform national decision-making.

METHOD

An Excel-based static cohort model was used to estimate the lifetime costs and health outcomes of vaccinating a single cohort of 9-year-old girls in the year 2018 with the bivalent HPV vaccine, compared to no vaccination. We also explored a scenario with a catch-up campaign for girls aged 10-14 years. Input parameters were based on local sources, published literature, or assumptions when no data was available. The primary outcome measure was the discounted cost per disability-adjusted life-year (DALY) averted, evaluated from both government and societal perspectives.

RESULTS

Vaccinating a single cohort of 9-year-old girls against HPV in Afghanistan could avert 1718 cervical cancer cases, 125 hospitalizations, and 1612 deaths over the lifetime of the cohort. The incremental cost-effectiveness ratio was US$426 per DALY averted from the government perspective and US$400 per DALY averted from the societal perspective. The estimated annual cost of the HPV vaccination program (US$3,343,311) represents approximately 3.53% of the country's total immunization budget for 2018 or 0.13% of total health expenditures.

CONCLUSION

In Afghanistan, HPV vaccine introduction targeting a single cohort is potentially cost-effective (0.7 times the GDP per capita of $586) from both the government and societal perspective with additional health benefits generated by a catch-up campaign, depending on the government's willingness to pay for the projected health outcomes.

Facial injury management undertaken at US and UK medical treatment facilities during the Iraq and Afghanistan conflicts: a retrospective cohort study

OBJECTIVES

To perform the first direct comparison of the facial injuries sustained and treatment performed at USA and UK deployed medical treatment facilities (MTFs) in support of the military campaigns in Iraq and Afghanistan.

SETTING

The US and UK Joint Theatre Trauma Registries were scrutinised for all patients with facial injuries presenting alive to a UK or US deployed MTF between 1 March 2003 and 31 October 2011.

PARTICIPANTS

US and UK military personnel, local police, local military and civilians.

PRIMARY AND SECONDARY OUTCOME MEASURES

An adjusted multiple logistic regression model was performed using tracheostomy as the primary dependent outcome variable and treatment in a US MTF, US or UK military, mandible fracture and treatment of mandible fracture as independent secondary variables.

RESULTS

Facial injuries were identified in 16 944 casualties, with the most common being those to skin/muscle (64%), bone fractures (36%), inner/middle ear (28%) and intraoral damage (11%). Facial injuries were equally likely to undergo surgery in US MTF as UK MTF (OR: 1.06, 95% CI 0.4603 to 1.142, p=0.6656); however, variations were seen in injury type treated. In US MTF, 692/1452 (48%) of mandible fractures were treated by either open or closed reduction compared with 0/167 (0%) in UK MTF (χ²: 113.6; p≤0.0001). US military casualties who had treatment of their mandible fracture (open reduction and internal fixation or mandibulo-maxillary fixation) were less likely to have had a tracheostomy than those who did not undergo stabilisation of the fractured mandible (OR: 0.61, 95% CI 0.44 to 0.86; p=0.0066).

CONCLUSIONS

The capability to surgically treat mandible fractures by open or closed reduction should be considered as an integral component of deployed coalition surgical care in the future.

Is recent Afghanistan survey data suitable for fertility analysis? A regional investigation based on fertility inhibiting determinants

Afghanistan has been a country blighted by war over the past five decades and limited research is available on its demography. This study seeks to assess the suitability of recent survey data for Afghanistan (the 2010 Afghanistan Mortality Survey (AMS)and the 2015 Afghanistan Demographic and Health Survey (ADHS)) for estimating levels and trends in fertility. As several fertility measures rely on the quality of age data, we first apply demographic tools for the identification of age misreporting, finding evidence that it is severe. We then explore the consistency of fertility reporting across the two surveys, finding that the 2015 ADHS reports higher fertility among older women than the 2010 AMS although the seasonal pattern of fertility is consistent across the two surveys. We then estimate total fertility rates in 2008–2010 and 2012–2015 and measures of Bongaarts’s key proximate determinants of fertility for Afghanistan and its provinces for urban and rural areas separately. The results show that fertility is similar in urban and rural Afghanistan. Although most of the provincial data on the proximate determinants is reasonably consistent with the fertility rates, there are anomalies in some provinces which indicate the possible under-reporting of births. Overall, we conclude that the fertility data in the two surveys can be used with care to give an indication of broad regional fertility patterns and trends in the country.

History and epidemiology of foot-and-mouth disease in Afghanistan: a retrospective study

BACKGROUND

Foot and mouth disease (FMD) is endemic in Afghanistan with serotypes O, A and Asia 1 being prevalent. A retrospective study of data collected through passive surveillance of outbreaks of FMD in Afghanistan from 1995 to 2016 was undertaken to determine the temporal and spatial distribution of FMD in the country.

RESULTS

A total of 4171 outbreaks were reported between 1995 and 2008 with a strong correlation between the number of outbreaks and the number of provinces (r = 0.85, s = 68.2, p < 0.001); and between the number of outbreaks and the number of districts containing infected animals (r = 0.68, s = 147.8, p = 0.008). Of 7558 samples collected from livestock originating from 34 provinces in 2009, 2011 and 2013-2015, 54.1% were test positive (FMDV 3ABC-trapping ELISA) and the prevalence varied significantly between years (χ2 = 263.98, df = 4, P < 0.001). Clinically suspected cases were reported in 2016 with a substantial positive correlation (r = 0.70, P < 0.001) between the number of districts with cases and the number of reported cases. Serotype O was the predominant serotype detected during the study period, although serotypes A and Asia1 were also detected. Cattle were involved in all outbreaks in the study period and infections were detected in all years of the study in Hirat province in the north-west (bordering Iran), Nangarhar province in the east (bordering Pakistan) and Kabul province in the centre of the country.

CONCLUSIONS

The current paper was the first analysis of existing data focusing on the spatiotemporal distribution of FMD in Afghanistan. The findings from this study provide valuable direction for further research to understand the epidemiology of FMD and its control in Afghanistan.

Effects of time-lagged meteorological variables on attributable risk of leishmaniasis in central region of Afghanistan

BACKGROUND

Leishmaniasis remains one of the world's most neglected vector-borne diseases, affecting predominantly poor communities mainly in developing countries. Previous studies have shown that the distribution and dynamics of leishmaniasis infections are sensitive to environmental factors, however, there are no studies on the burden of leishmaniasis attributable to time-varying meteorological variables.

METHODS

This study used data from 3 major leishmaniosis afflicted provinces of Afghanistan, between 2003 and 2009, to provide empirical analysis of change in heat/cold-leishmaniosis association. Non-linear and delayed exposure-lag-response relationship between meteorological variables and leishmaniasis were fitted with a distributed lag non-linear model applying a spline function which describes the dependency along the range of values with a lag of up to 12 months. We estimated the risk of leishmaniasis attributable to high and low temperature.

RESULTS

The median monthly mean temperature and rainfall were 16.1 °C and 0.6 in., respectively. Seasonal variations of leishmaniasis were consistent between males and females, however significant differences were observed among different age groups. Temperature effects were immediate and persistent (lag 0-12 months). The cumulative risks were highest at cold temperatures. The cumulative relative risks (logRR) for leishmaniasis were 6.16 (95% CI: 5.74-6.58) and 1.15 (95% CI: 1.32-1.31) associated with the 10th percentile temperature (2.16 °C) and the 90th percentile temperature (28.46 °C). The subgroup analysis showed increased risk for males as well as young and middle aged people at cold temperatures, however, higher risk was observed for the elderly in heat. The overall leishmaniasis-temperature attributable fractions was estimated to be 7.6% (95% CI: 7.5%-7.7%) and mostly due to cold.

CONCLUSION

Findings in this study highlight the non-linearity, delay of effects and magnitude of leishmaniasis risk associated with temperature. The disparity of risk between different subgroups can hopefully advise policy makers and assist in leishmaniasis control program.

Elimination of morbidity due to soil-transmitted helminthiases among Afghan schoolchildren

Large sectors of the Afghan population have limited access to safe water and sanitation, which increases the risk of transmission of water- and food- borne diseases, including Soil-Transmitted Helminth (STH) infections. STHs interfere with the human host's health status, and their burden of disease is highest among children of school age. Based on the results of a nationwide survey conducted in 2003, which showed an STH prevalence of 47.2%, and with the aim of reducing morbidity among school children, Afghanistan has been conducting nationwide deworming for preschool-age and school-age children since 2004. In 2017, 14 years after the first baseline assessment, a follow-up survey was carried out among schoolchildren aged 8-10 years to provide an update on STH epidemiology and facilitate evidence-informed planning of future deworming campaigns. Stool samples were collected from 2263 pupils aged 8-10 years in five provinces representing the different ecological zones of the country - Kabul, Balkh, Herat, Nangarhar and Kandahar. Microscopic examination was carried out by the Kato-Katz thick smear technique, to assess the presence and the number of parasites and/or their eggs. The survey revealed that 26.6% of the sample was infected with at least one of the STH, a marked decrease from the level registered in 2003. The most prevalent infection was the one with A. lumbricoides (25.7%), followed by T. trichiura (1.0%) and hookworms (0.1%). All positive children were noted to have light-intensity infections, compared to the previous survey where 9.7% of the sample had moderate-to-heavy intensity infections. Only 0.2% of the children had co-infection with two or more parasites. Meanwhile, 6.8% of the students were found infected with the dwarf tapeworm, Hymenolepis nana. The absence of infections of moderate-to-heavy intensity after several yearly rounds of deworming and overall improvements in provision of safe water and sanitation, indicates successful control of morbidity due to STH and, overall, their elimination as a public-health problem from Afghanistan. Nevertheless, current levels of prevalence of infection still show persistence of active transmission of STHs, thus justifying the continued implementation of mass deworming interventions among children. The permanent elimination of STH transmission, however, will be possible only when the country reaches a sanitation level sufficient to impede fecal contamination of the environment with human excreta.

A Comparison of Prehospital Versus Emergency Department Intubations in Iraq and Afghanistan

BACKGROUND

Airway obstruction is the second most common cause of potentially preventable death on the battlefield. We compared survival in the combat setting among patients undergoing prehospital versus emergency department (ED) intubation.

METHODS

Patients were identified from the Department of Defense Trauma Registry (DODTR) from January 2007 to August 2016. We defined the prehospital cohort as subjects undergoing intubation prior to arrival to a forward surgical team (FST) or combat support hospital (CSH), and the ED cohort as subjects undergoing intubation at an FST or CSH. We compared study variables between these cohorts; survival was our primary outcome.

RESULTS

There were 4341 intubations documented in the DODTR during the study period: 1117 (25.7%) patients were intubated prehospital and 3224 (74.3%) were intubated in the ED. Patients intubated prehospital had a lower median age (24 versus 25 years, p < .001), composed a higher proportion of host nation forces (36.1% versus 29.1%, p < .001), had a lower proportion of injuries from explosives (57.6% versus 61.0%, p = .030), and had higher median injury severity scores (20 versus 18, p = .045). A lower proportion of the prehospital cohort survived to hospital discharge (76.4% versus 84.3%, p < .001). The prehospital cohort had lower odds of survival to hospital discharge in both univariable (odds ratio [OR] 0.60, 95% confidence interval [CI] 0.51-0.71) and multivariable analyses controlling for confounders (OR 0.70, 95% CI 0.58-0.85). In a subgroup analysis of patients with a head injury, the lower odds of survival persisted in the multivariable analysis (OR 0.49, 95% CI 0.49-0.82).

CONCLUSIONS

Patients intubated in the prehospital setting had a lower survival than those intubated in the ED. This finding persisted after controlling for measurable confounders.

Crimean-Congo Hemorrhagic Fever, Herat Province, Afghanistan, 2017

We studied the clinical and epidemiologic features of an outbreak of Crimean-Congo hemorrhagic fever in Herat Province, Afghanistan. The study comprised 63 patients hospitalized in 2017. The overall case-fatality rate was 22.2%; fatal outcome was significantly associated with a negative IgM test result, longer prothrombin time, and nausea.
