Community based multi-disease health screening as an opportunity for early detection of HIV cases and linking them to care.

BACKGROUND: The 95-95-95 UNAIDS global strategy was adapted to end the AIDS epidemic by 2030. The target is based on the premise that early detection of HIV-infected persons and linking them to treatment regardless of their CD4 counts will lead to sustained viral suppression. HIV testing strategies to increase uptake of testing in Western and Central Africa remain inadequate. Hence, a high proportion of people living with HIV in this region do not know their status. This report describes the implementation of a community based multi-disease health screening (also known as "Know Your Status" -KYS), as part of basic science research, in a way that contributed to achieving public health goals. METHODS: A community based multi-disease health screening was conducted in 7 communities within the Eastern region of Ghana between November 2017 and April 2018, to recruit and match HIV seronegative persons to HIV seropositive persons in a case-control HIV gut microbiota study. Health assessments included blood pressure, body mass index, blood sugar, Hepatitis B virus, syphilis, and HIV testing for those who consented. HIV seronegative participants who consented were consecutively enrolled in an ongoing HIV gut microbiota case-control study. Descriptive statistics (percentages) were used to analyze data. RESULTS: Out of 738 people screened during the exercise, 700 consented to HIV testing and 23 (3%) were HIV positive. Hepatitis B virus infection was detected in 4% (33/738) and Syphilis in 2% (17/738). Co-infection of HIV and HBV was detected in 4 persons. The HIV prevalence of 3% found in these communities is higher than both the national prevalence of 1.7% and the Eastern Regional prevalence of 2.7 in 2018. CONCLUSION: Community based multi-disease health screening, such as the one undertaken in our study could be critical for identifying HIV infected persons from the community and linking them to care. In the case of HIV, it will greatly contribute to achieving the first two 95s and working towards ending AIDS by 2030.

Cost of postoperative complications of lower anterior resection for rectal cancer: a nationwide registry study of 15,187 patients.

PURPOSE: To assess the increase in hospital costs associated with postoperative complications after lower anterior resection (LAR) for rectal cancer. METHODS: The subjects of this retrospective analysis were patients who underwent elective LAR surgery between April, 2015 and March, 2017, collected from a Japanese nationwide gastroenterological surgery registry linked to hospital-based claims data. We evaluated total and category-specific hospitalization costs based on the level of postoperative complications categorized using the Clavien-Dindo (CD) classification. We assessed the relative increase in hospital costs, adjusting for preoperative factors and hospital case volume. RESULTS: We identified 15,187 patients (mean age 66.8) treated at 884 hospitals. Overall, 71.8% had no recorded complications, whereas 7.6%, 10.8%, 9.0%, 0.6%, and 0.2% had postoperative complications of CD grades I-V, respectively. The median (25th-75th percentiles) hospital costs were $17.3 K (16.1-19.3) for the no-complications group, and $19.1 K (17.3-22.2), $21.0 K (18.5-25.0), $27.4 K (22.4-33.9), $41.8 K (291-618), and $22.7 K (183-421) for the CD grades I-V complication groups, respectively. The multivariable model identified that complications of CD grades I-V were associated with 11%, 21%, 61%, 142%, and 70% increases in in-hospital costs compared with no complications. CONCLUSIONS: Postoperative complications and their severity are strongly associated with increased hospital costs and health-care resource utilization. Implementing strategies to prevent postoperative complications will improve patients' clinical outcomes and reduce hospital care costs substantially.

End-of-life care for cancer patients in Japanese acute care hospitals: A nationwide retrospective administrative database survey.

BACKGROUND: End-of-life (EOL) cancer care in Japanese acute care hospitals has not been well described. METHODS: We aimed to assess the aggressiveness of EOL care and examine common treatments administered to cancer patients using a health administrative database. Subjects are adult cancer patients who died at acute care hospitals between April 2011 and March 2014. Data from the Japanese Diagnosis Procedure Combination database were analysed to measure the aggressiveness of care (chemotherapy, intensive care unit [ICU] admission and cardiopulmonary resuscitation [CPR]) and describe procedures and prescriptions administered in the last 14 and 30 days of life, disaggregated by hospital case volume: high, intermediate and low volumes. RESULTS: Of 248,978 cancer decedents, 170,024 died in high-, 70,231 in intermediate- and 8,723 in low-volume hospitals. Aggressive treatment in the last 14 days of life included chemotherapy (9.4%, 7.3%, and 5.4%, respectively), ICU admission (3.0%, 2.0%, and 2.4%) and CPR (5.8%, 6.4%, and 8.3%). Opioids were administered to 66.0%, 59.0% and 49.4% patients, while Palliative Care Team intervention was performed for 8.5%, 2.2% and 2.0% of patients, respectively in the last 30 days. In high-volume hospitals, radiotherapy and certified outpatient chemotherapy fees were more frequent. Catecholamines and hyperalimentation were more frequently administered in low-volume hospitals. CONCLUSION: This is the first study to assess EOL care among Japanese acute care hospitals. More frequent use of chemotherapy at high-volume hospitals may reflect a well-established cancer treatment system. The approach for low-volume hospitals might improve the EOL care for all cancer patients in Japan.

Geographic Access to Cancer Treatment in Japan: Results From a Combined Dataset of the Patient Survey and the Survey of Medical Institutions in 2011.

BACKGROUND: There has been no nationwide analysis of travel time for hospital admission in Japan. Factors associated with travel time are also unknown. This study aimed to describe the distribution of travel time for hospital admission of cancer patients and identify underlying factors. METHODS: The individual data from the Patient Survey in 2011 were linked to those from the Survey of Medical Institutions in the same year, and GIS data were used to calculate driving travel time between the addresses of medical institutions and the population centers of municipalities where patients lived. Proportions of patients with travel time exceeding versus not exceeding 45 minutes were calculated. To analyze the data with consideration of both individual factors of patients and geographical characteristics of areas where patients lived, multilevel logistic model analysis was performed. RESULTS: The analysis included 50,845 cancer inpatients. The majority of the cancer patients (approximately 80%) were admitted to hospitals located less than a 45-minute drive from their residences. The travel time tended to be longer for younger patients. The proportion of patients with travel time ≥45 minutes was lower among those with stomach or colorectal cancer (approximately 15%) than those with cervical cancer or leukemia (approximately 30%). The lack of designated cancer care hospitals in the secondary healthcare service areas was significantly associated with travel time. CONCLUSIONS: Selection of hospitals by cancer inpatients is affected by age, cancer sites, and availability of designated cancer care hospitals in the secondary healthcare service areas where patients live.

Population Genetic Structure of QoI-Resistant Pestalotiopsis longiseta Isolates Causing Tea Gray Blight.

Resistance to the quinone outside inhibitor (QoI) fungicides in the tea gray blight-causing fungus Pestalotiopsis longiseta is a serious problem in Japanese tea cultivation. We conducted a population genetic analysis of QoI-resistant P. longiseta isolates on the Makinohara Plateau, Shizuoka Prefecture, Japan's largest tea-growing area, to elucidate the disease's epidemiology and the spread of QoI resistance. Inter simple sequence repeat (ISSR) analysis of 1,083 isolates from 395 fields collected from 2009 to 2012 detected 42 ISSR types, designated as PL01 to PL42. A total of 18, seven, and 38 ISSR types were detected in highly resistant, moderately resistant, and sensitive isolates, respectively. No distinct phylogenetic relationship corresponding to QoI sensitivity or sampling location was observed. No annual changes in the population genetic structure of highly resistant isolates were observed during the study period. A different ISSR type was predominant among QoI-resistant isolates in each region. Analysis of molecular variance revealed significant genetic differentiation in populations of highly resistant isolates among regions (FCT = 0.213) and farmers (FCT = 0.071). Consequently, we speculate that QoI-resistant P. longiseta strains occurred in a number of clonal lineages and spread by both natural and artificial transmission, such as rain splash and plucking machines, throughout each region on the Makinohara Plateau.

Medical Big Data for Research Use: Current Status and Related Issues.

Advances in the computerization of information and development of technology have mitigated restrictions on handling of a large amount of information. This has resulted in growth of expectations for the use of large-scale databases, or so-called "big data." This is also the case in the field of healthcare. Projects that involve building of the national receipt database (NDB) of medical fee bill (receipt) information and special health check-up information based on the Act on Assurance of Medical Care for Elderly People and the development of medical information databases have been pursued by the national government, and considerable attention has also been focused on researches conducted through the secondary uses of publicly collected data. Aside from these trends, there are numerous projects which collect diagnosis procedure combination (DPC) data to build large-scale databases for research purposes. Following to the ethics guidelines for epidemiologic studies, they collect and analyze anonymized DPC data from cooperating institutions. This communication concentrates on the use of DPC data, and outlines the scale of data currently available for research use. Examples on the use of DPC data will be shown for analysis on the current status of clinical practice from the microscopic perspective and macroscopic analysis of community medical care provision. Additionally, potential for extending studies to long-term outcomes research, limitations and issues related to the use of medical big data will also be discussed.

The impact of comprehensive stroke care capacity on the hospital volume of stroke interventions: a nationwide study in Japan: J-ASPECT study.

BACKGROUND: The association between comprehensive stroke care capacity and hospital volume of stroke interventions remains uncertain. We performed a nationwide survey in Japan to examine the impact of comprehensive stroke care capacity on the hospital volume of stroke interventions. METHODS: A questionnaire on hospital characteristics, having tissue plasminogen activator (t-PA) protocols, and 25 items regarding personnel, diagnostic, specific expertise, infrastructure, and educational components recommended for comprehensive stroke centers (CSCs) was sent to 1369 professional training institutions. We examined the effect of hospital characteristics, having a t-PA protocol, and the number of fulfilled CSC items (total CSC score) on the hospital volume of t-PA infusion, removal of intracerebral hemorrhage, and coiling and clipping of intracranial aneurysms performed in 2009. RESULTS: Approximately 55% of hospitals responded to the survey. Facilities with t-PA protocols (85%) had a significantly higher likelihood of having 23 CSC items, for example, personnel (eg, neurosurgeons: 97.3% versus 66.1% and neurologists: 51.3% versus 27.7%), diagnostic (eg, digital cerebral angiography: 87.4% versus 43.2%), specific expertise (eg, clipping and coiling: 97.2% and 54% versus 58.9% and 14.3%, respectively), infrastructure (eg, intensive care unit: 63.9% versus 33.9%), and education (eg, professional education: 65.2% versus 20.7%). On multivariate analysis adjusted for hospital characteristics, total CSC score, but not having a t-PA protocol, was associated with the volume of all types of interventions with a clear increasing trend (P for trend < .001). CONCLUSION: We demonstrated a significant association between comprehensive stroke care capacity and the hospital volume of stroke interventions in Japan.

Longitudinal analysis of microbiome composition in Ghanaians living with HIV-1.

Human immunodeficiency virus (HIV) 1 infection is known to cause gut microbiota dysbiosis. Among the causes is the direct infection of HIV-1 in gut-resident CD4+ T cells, causing a cascade of phenomena resulting in the instability of the gut mucosa. The effect of HIV infection on gut microbiome dysbiosis remains unresolved despite antiretroviral therapy. Here, we show the results of a longitudinal study of microbiome analysis of people living with HIV (PLWH). We contrasted the diversity and composition of the microbiome of patients with HIV at the first and second time points (baseline_case and six months later follow-up_case, respectively) with those of healthy individuals (baseline_control). We found that despite low diversity indices in the follow-up_case, the abundance of some genera was recovered but not completely, similar to baseline_control. Some genera were consistently in high abundance in PLWH. Furthermore, we found that the CD4+ T-cell count and soluble CD14 level were significantly related to high and low diversity indices, respectively. We also found that the abundance of some genera was highly correlated with clinical features, especially with antiretroviral duration. This includes genera known to be correlated with worse HIV-1 progression (Achromobacter and Stenotrophomonas) and a genus associated with gut protection (Akkermansia). The fact that a protector of the gut and genera linked to a worse progression of HIV-1 are both enriched may signify that despite the improvement of clinical features, the gut mucosa remains compromised.

Associations between the use of critical care procedures and change in functional status at discharge.

Quality improvement initiatives in intensive care units (ICUs) have increased survival rates. Changes in functional status following ICU care have been studied, but results are inconclusive because of insufficient consideration of the combinations of critical care procedures used. Using the Japanese administrative database including the Barthel Index (BI) at admission and discharge, we measured the changes in functional status among the adult patients and determined whether longer ICU stay or use of various critical care procedures was associated with functional deterioration. Of the 12 502 528 patients admitted to 1206 hospitals over 5 consecutive years from 2006, we analyzed data from patients aged 15 years or older who survived ICU admission in 320 hospitals. Critical care procedures evaluated were ventilation, blood purification (hemodialysis, hemodiafiltration, or hemadsorption), and cardiac support devices (intra-aortic balloon pump or percutaneous cardiopulmonary support system). Functional outcomes were determined by the difference between BI at admission and at discharge and were divided into improvement, no change, or deterioration. We compared patient characteristics, principal diagnosis, comorbidities, timing of surgical procedure, complications, days in ICU, and use of critical care procedures among the 3 categories. Associations between critical care procedures and functional deterioration were identified using multivariate analysis. Of 234 209 patients with complete BI information, 7137 (3.1%) received blood purification, 27 100 (11.7%) received ventilation, 2888 (1.2%) received blood purification and ventilation, 5613 (2.4%) received a cardiac support device, 247 (0.1%) received a cardiac support device and blood purification, 10 444 (4.5%) received a cardiac support device and ventilation, and 1110 (0.5%) received a cardiac support device, ventilation, and blood purification. Longer use of blood purification or ventilation and a longer ICU stay were associated with functional deterioration. Intensivists should be aware of the effects of critical care procedures on functional deterioration and advance the appropriate use of functional support according to each patient's condition.

A community-based comparison of trauma patient outcomes between D- and L-lactate fluids.

PURPOSE: Ringer's lactate is used for patient resuscitation. Lactate naturally occurs in 2 stereoisometric forms, D- and L-lactate, that are added to fluid in equal amounts. Animal studies have demonstrated potentially deleterious effects of d-lactate on vital organs. Using an administrative database, we examined whether D- or L-lactate volume was associated with mortality in patients with trauma. BASIC PROCEDURES: The Trauma and Injury Severity Score could be calculated in 24,616 of 528,219 patients admitted in 2006 to 2009. Demographic characteristics, the use of blood products, mechanical ventilation, and mortality were compared among the following 3 groups of patients administered Ringer's lactate: group 1, fluids other than Ringer's lactate; group 2, fluids including Ringer's DL-lactate; and group 3, no D-lactate. The mean volume (in millimoles per day) of D- and L-lactate administered was calculated. Multivariate analyses were used to measure the impact of lactate volume on mortality, and mechanical ventilation started more than 48 hours after admission. MAIN FINDINGS: Groups 2 and 3 consisted of 2,827 (11.5%) patients (88 hospitals) and 12,036 (48.9%) patients (145 hospitals), respectively. The use of mechanical ventilation best explained the variation in mortality. Greater d-lactate volume, but not fluid management category or L-lactate volume, was associated with mortality. L-Lactate decreased and D-lactate increased the use of mechanical ventilation more than 48 hours after admission. CONCLUSIONS: Because early administration of D-lactate was associated with mortality and ventilation, physicians and policy makers should recognize the advantages of L-lactate and encourage research on the quality of d- and l-lactate in case mixes beyond trauma.

Clarification of Factors Determining Discharge Destination Among Elderly Patients After Stroke With Low Levels of Independence in Activities of Daily Living: A Retrospective Study.

Objective: To determine factors influencing discharge destination of elderly patients after stroke with low levels of independence in activities of daily living (ADL). Design: Cross-sectional study. Setting: A community-based public hospital in a rural area in Japan. Participants: A total of 67 patients with low daily function among 205 elderly patients with stroke screened for eligibility (N=67). Interventions: Not applicable. Main Outcome Measures: Motor component of functional independence measure (M-FIM) at discharge and discharge destination-home or long-term care facility (LCF). Results: Among the 205 eligible patients, 147 were discharged home and 58 were discharged to LCFs. Patients with an M-FIM score of ≤30 at discharge were defined as patients deemed difficult to discharge home because of low independence levels in ADL. Of the 147 patients discharged home, 24 (16.3%) had M-FIM scores of ≤30. Of the 58 patients discharged to LCFs, 43 (74.1%) had M-FIM scores of ≤30. Patients with an M-FIM score of ≤30 at discharge significantly tended to be discharged home if they obtained oral intake vs tube feeding as a nutritional method (P=.047) and higher cognitive component of FIM scores at discharge (P=.002). All six patients who lived alone among patients with an M-FIM score of ≤30 were discharged to LCFs. Two patients on tube feeding were discharged home. Conclusions: Nutritional method, cognitive function at discharge, and the prestroke living situation with or without household caregivers are important factors of discharge among elderly patients after stroke with low independence levels in ADL. However, only a small number of severely disabled patients were successfully discharged home.

Factors Associated With Time to Achieve Physical Functional Recovery in Patients With Severe Stoke After Inpatient Rehabilitation: A Retrospective Nationwide Cohort Study in Japan.

Objective: To describe characteristics of patient with severe stroke (FIM motor score [FIM motor] 20-49 at admission) and examine association between pre-specified factors (age, sex, modified Rankin Scale before stroke onset, body mass index, FIM motor, and FIM cognitive) and time to achieve FIM motor ≥70, that is, self-independent level. Design: Retrospective cohort study using a large database in Japan. Setting: Rehabilitation wards. Participants: Patients with severe stroke (N=1422) who received inpatient rehabilitation were included (median age: 76 years; interquartile range [IQR]: 68.0-84.0). A total of 54.6% were men, and 65.8% were ischemic stroke. Interventions: Not applicable. Main Outcome Measures: Time to achieve FIM motor ≥70. Results: After inpatient rehabilitation, 40.4% (N=575) achieved FIM motor ≥70 (admission FIM motor 20-29, 30-39 and 40-49: 18.6%, 33.6%, and 47.8%, respectively). Patients who achieved FIM motor ≥70 stayed median 81.0 days [IQR, 51.0-120.0]) and received median: 6.94 units per day [IQR, 5.48-7.78], 1 unit=20 minutes). Adjusted Fine-Gray regression revealed that shorter time to achieve FIM motor ≥70 was associated with higher admission FIM motor (hazard ratio [HR] 2.87 [95% confidence interval [CI] 2.27-3.62]: 20-29 vs 40-49), higher admission FIM cognitive (HR 1.81 [95% CI: 1.39-2.35]: 5-14 vs 25-35), and younger (HR 3.20 [95% CI: 2.32-4.42]: ≥85 years vs 20-69 years). Conclusions: Most patients with severe stroke did not achieve FIM motor ≥70 after inpatient rehabilitation. Older patients and patients with lower admission FIM motor require more attention. They should be prioritized for state-of-the-art rehabilitation therapy.

Assessment of the Proportion of Recent HIV-1 Infections in Newly-Diagnosed Cases in Ghana.

Accurate monitoring of epidemics is a key strategy for controlling human immunodeficiency virus type-1 (HIV-1) infection. To delineate the characteristics of newly diagnosed cases of HIV-1 infection, we assessed the proportion of recent HIV-1 infections using a recent infection-testing algorithm (RITA). In 2015, 248 cases were newly diagnosed with HIV infection at the Regional Hospital Koforidua, Ghana. Of these, 234 cases (94.4%) were infected with HIV-1 only, four (1.6%) were infected with HIV-2 only, and 10 (4.0%) were co-infected with HIV-1 and HIV-2. All HIV-1 single-seropositive samples were used in the HIV-1 LAg avidity assay for RITA. Our analysis revealed that 18 cases (7.7%) were recently infected, indicating that early diagnosis was not achieved in Ghana. This is the first report to assess the proportion of recent infections in Ghana using a biomarker approach. The accumulation of these data will contribute to the accurate estimation of HIV-1 incidence and prevalence in Ghana.

Strengthening surveillance in Ghana against public health emergencies of international concern.

Among western African countries, the Republic of Ghana has maintained an economic growth rate of 5% since the 1980s and is now categorized as a middle-income country. However, as with other developing countries, Ghana still has challenges in the effective implementation of surveillance for infectious diseases. Facing public health emergencies of international concern (PHEIC), it is crucial to establish a reliable sample transportation system to the referral laboratory. Previously, surveillance capacity in Ghana was limited based on Integrated Disease Surveillance and Response, and therefore the "Surveillance and Laboratory Support for Emerging Pathogens of Public Health Importance in Ghana (SLEP)" was introduced to strengthen diarrhea surveillance. The SLEP project started with a sentinel diarrhea survey supported by SATREPS/JICA in collaboration with National Public Health Reference Laboratory (NHPRL) and Noguchi Memorial Institute of Medicine (NMIMR). The base-line survey revealed the limited capacity to detect diarrhea pathogens and to transfer samples from health centers to NHPRL. The involvement of private clinic/hospital facilities into the surveillance network is also crucial to strengthen surveillance in Ghana. The strong and interactive relationship between the two top referral laboratories, NHPRL under the Ministry of Health NMIMR and under the Ministry of Education, enables Ghana Health Services and is critical for the rapid response against PHEIC. In future, we hope that the outcome of the SLEP surveillance project could contribute to building a surveillance network with more timely investigation and transfer of samples to referral labs.

Super high-resolution single-molecule sequence-based typing of HLA class I alleles in HIV-1 infected individuals in Ghana.

Polymorphisms in human leukocyte antigen (HLA) class I loci are known to have a great impact on disease progression in HIV-1 infection. Prevailing HIV-1 subtypes and HLA genotype distribution are different all over the world, and the HIV-1 and host HLA interaction could be specific to individual areas. Data on the HIV-1 and HLA interaction have been accumulated in HIV-1 subtype B- and C-predominant populations but not fully obtained in West Africa where HIV-1 subtype CRF02_AG is predominant. In the present study, to obtain accurate HLA typing data for analysis of HLA association with disease progression in HIV-1 infection in West African populations, HLA class I (HLA-A, -B, and -C) four-digit allele typing was performed in treatment-naïve HIV-1 infected individuals in Ghana (n = 324) by a super high-resolution single-molecule sequence-based typing (SS-SBT) using next-generation sequencing. Comparison of the SS-SBT-based data with those obtained by a conventional sequencing-based typing (SBT) revealed incorrect assignment of several alleles by SBT. Indeed, HLA-A*23:17, HLA-B*07:06, HLA-C*07:18, and HLA-C*18:02 whose allele frequencies were 2.5%, 0.9%, 4.3%, and 3.7%, respectively, were not determined by SBT. Several HLA alleles were associated with clinical markers, viral load and CD4+ T-cell count. Of note, the impact of HLA-B*57:03 and HLA-B*58:01, known as protective alleles against HIV-1 subtype B and C infection, on clinical markers was not observed in our cohort. This study for the first time presents SS-SBT-based four-digit typing data on HLA-A, -B, and -C alleles in Ghana, describing impact of HLA on viral load and CD4 count in HIV-1 infection. Accumulation of these data would facilitate high-resolution HLA genotyping, contributing to our understanding of the HIV-1 and host HLA interaction in Ghana, West Africa.

Diarrhea-Causing Bacteria and Their Antibiotic Resistance Patterns Among Diarrhea Patients From Ghana.

Diarrheal disease remains a major global health problem particularly in children under 5 years and the emergence of antibiotic-resistant strains of causative pathogens could slow control efforts, particularly in settings where treatment options are limited. This surveillance study conducted in Ghana aimed to determine the prevalence and antimicrobial susceptibility profile of diarrhea-causing bacteria. This was a cross-sectional study carried out in five health facilities in the Ga West Municipality of Ghana between 2017 and 2021. Diarrheic stool samples from patients were collected and cultured on standard differential/selective media and isolates identified by standard biochemical tests, MALDI-TOF assay, and serological analysis. The antibiogram was determined using Kirby-Bauer disk diffusion and Microscan autoScan4 MIC panels which were used for extended-spectrum beta-lactamase (ESBL) detection. Bacteria were isolated from 97.5% (772/792) of stool samples, and 167 of the isolates were diarrheagenic and met our inclusion criteria for antimicrobial resistance (AMR) analysis. These included Escherichia coli (49.1%, 82/167), Salmonella species (23.9%, 40/167), Vibrio species (16.8%, 28/167), and Shigella species (10.2%, 17/167). Among 24 Vibrio species, we observed resistances to cefotaxime (21/24, 87.5%), ceftriaxone (20/24, 83.3%), and ciprofloxacin (6/24, 25%), including four multi-drug resistant isolates. All 13 Vibrio parahaemolyticus isolates were resistant to cefazolin. All 17 Shigella isolates were resistant to tetracycline with resistance to shigellosis drugs such as norfloxacin and ciprofloxacin. Salmonella isolates were highly susceptible to norfloxacin (40/40, 100%) and tetracycline (12/34, 35%). Two ESBL-producing E. coli were also identified with marked susceptibility to gentamicin (66/72, 91.7%) and amikacin (57/72, 79.2%) prescribed in the treatment of E. coli infections. This study showed the different bacteria implicated in diarrhea cases in Ghana and the need for differential diagnoses for better treatment outcomes. Escherichia coli, Shigella, Salmonella, and Vibrio have all been implicated in diarrhea cases in Ghana. The highest prevalence was E. coli and Salmonella with Shigella the least prevalent. Resistance to commonly used drugs found in these isolates may render bacteria infection treatment in the near future nearly impossible. Routine antimicrobial susceptibility testing, effective monitoring, and nationwide surveillance of AMR pathogens should be implemented to curb the increase of antimicrobial resistance in Ghana.

High-level resistance to non-nucleos(t)ide reverse transcriptase inhibitor based first-line antiretroviral therapy in Ghana; A 2017 study.

Expanding access to effective antiretroviral therapy (ART) is a major tool for management of Human Immunodeficiency Virus (HIV) infection. However, rising levels of HIV drug-resistance have significantly hampered the anticipated success of ART in persons living with HIV (PLWH), particularly those from Africa. Though great strides have been made in Ghana toward achieving the UNAIDS "95-95-95" target, a substantial number of PLWH receiving ART have not attained viral suppression. This study investigated patterns of drug resistance mutations in ART naïve as well as ART-experienced PLWH receiving first-line regimen drugs from Ghana. In a cross-sectional study, blood samples were collected from HIV-1 infected adults (≥18 years) attending HIV/AIDS clinic at the Eastern Regional Hospital, Koforidua, Ghana from September to October 2017. Viral RNA isolated from plasma were subjected to genotypic drug resistance testing for Protease Inhibitors (PI), Reverse Transcriptase Inhibitors (RTI), and Integrase Strand Transfer Inhibitors (INSTI). A total of 95 (84 ART experienced, 11 ART naïve) HIV-1 infected participants were sampled in this study. Sixty percent (50/84) of the ART-experienced participants were controlling viremia (viral load < 1,000 copies/ml). Of the 95 patient samples, 32, 34, and 33 were successfully sequenced for protease, reverse-transcriptase, and integrase regions, respectively. The dominant HIV-1 subtypes detected were CRF02_AG (70%), and A3 (10%). Major drug resistance associated mutations were only detected for reverse transcriptase inhibitors. The predominant drug resistance mutations were against nucleos(t)ide reverse transcriptase inhibitors (NRTI)-M184V/I and non-nucleos(t)ide reverse transcriptase inhibitors (NNRTI)-K103N. In the ART-experienced group, M184V/I and K103N were detected in 54% (15/28) and 46% (13/28) of individuals, respectively. Both mutations were each detected in 33% (2/6) of ART naïve individuals. Multiclass resistance to NRTI and NNRTI was detected in 57% of ART-experienced individuals and two ART naïve individuals. This study reports high-level resistance to NNRTI-based antiretroviral therapy in PLWH in Ghana. However, the absence of major PI and INSTI associated-mutations is a good signal that the current WHO recommendation of Dolutegravir in combination with an NRTI backbone will yield maximum benefits as first-line regimen for PLWH in Ghana.

Quantitative assessment of the advantages of laparoscopic gastrectomy and the impact of volume-related hospital characteristics on resource use and outcomes of gastrectomy patients in Japan.

OBJECTIVE: In this community-based study, we assessed the advantages of laparoscopic gastrectomy (LG) and the impact of volume-related hospital characteristics on gastrectomy care. BACKGROUND: The quality of gastrectomy care and the potential effects of volume-related hospital characteristics on gastrectomy care have not been comprehensively evaluated to date. METHODS: We used a Japanese administrative database of 17,761 patients across 258 hospitals delivering both open gastrectomy and LG during 6-month periods in 2006, 2007, and 2008. We examined patient demographics, principal diagnosis, comorbidities, and complications, hospital patient volume, proportion of LG procedures accomplished, teaching status and care processes, length of hospital stay, total charge, and operative time. Multivariate analyses were used to compare LG with open gastrectomy in terms of mortality, complications, operative or postoperative blood transfusion, resource use and operative time. RESULTS: LG was performed in 3,914 (22%) patients and was associated with significantly shorter length of hospital stay, lower total charge, and longer operative time. Higher hospital volume was associated with less mortality, lower frequency of transfusion, shorter length of hospital stay, lower total charge, and shorter operative time. Higher procedures accomplished were associated with fewer complications, higher frequency of transfusion, greater resource use, and longer operative time. CONCLUSIONS: Laparoscopic gastrectomy offers significant economic advantages over open gastrectomy. However, LG was associated with increased operative time and required greater blood transfusion volume once indicated, which might drive gastrectomy care to use more prudent approaches in hospitals with higher procedures accomplished rates. Stakeholders should recognize the wide variation in hospital practices, skill training and efficient gastrectomy care, in addition to the volume-quality relationship.

Early crystalloid fluid volume management in acute pancreatitis: association with mortality and organ failure.

AIMS: Guidelines recommend aggressive fluid resuscitation in patients with acute pancreatitis (AP) to minimize organ failure. This study aimed to determine whether early crystalloid fluid management is associated with mortality and/or critical care. METHODS: 9,489 AP patients aged ≥18 years were categorized into four study groups: ventilation, hemodialysis, a combination of ventilation and hemodialysis, and neither ventilation nor hemodialysis. We analyzed demographics, mortality, comorbidities, complications, AP severity, surgery of the biliary/pancreatic system, and fluid volume (FV) during the initial 48 h (FV48) and during hospitalization (FVH), and calculated the FV ratio (FVR) as FV48/FVH. The impact of FV48 and FVR on mortality and the care process was assessed according to AP severity. RESULTS: 1.1% of AP patients received ventilation, 1.7% received hemodialysis and 1.0% received both treatments. FV48 and FVR were higher in patients requiring ventilation compared with those not requiring ventilation. A high FV48 increased mortality and a high FVR decreased mortality in patients with severe AP. A high FV48 required ventilation in patients with severe AP, which was independently associated with mortality. CONCLUSION: Since relatively too much or too little early FV is associated with mortality, FV should be continuously monitored and managed according to AP severity. and IAP.

Community-based appraisal of laparoscopic abdominal surgery in Japan.

BACKGROUND: Despite the prevalence of laparoscopic surgery (LS), community-based appraisal of its benefit over open surgery (OS) has not been performed. This can be measured by increased total charge (TC) spent and decreased length of stay (LOS), which are indicative of greater resource use and opportunistic cost reduction. We prioritized the value of LS for eight abdominal procedures. MATERIALS AND METHODS: We used a Japanese administrative database for the 6 mo leading up to December 2007. Study procedures were appendectomy, cholecystectomy, choledocholithotomy, herniorrhaphy, colectomy, partial or total gastrectomy, and small bowel resection (SBR) in adults. We analyzed patient demographics, mortality, comorbidity, complications, use of chemotherapy or postoperative pain control, hospital teaching status, postoperative LOS, and TCs. The impact of LS was determined using multivariate analysis on the propensity-score-matched cohorts of LS and OS. RESULTS: Herniorrhaphy was most frequently performed (24,088 cases), whereas SBR was performed least (3404). LS was performed most often in cholecystectomy (81%) and least in herniorrhaphy (3.7%). LS did not increase complications in any procedure. Laparoscopic cholecystectomy and SBR were associated with shorter LOS and lower TC, whereas laparoscopic herniorrhaphy increased LOS and TC. Laparoscopic appendectomy and partial gastrectomy reduced LOS and increased TC. CONCLUSIONS: LS safety was confirmed. Laparoscopic cholecystectomy or SBR might have advantages, whereas laparoscopic was no better than open herniorrhaphy and might be decided by patient's preference. Considering the variation in the decremental opportunistic cost produced by incremental medical expenses observed among the procedures, policymakers should determine an appropriate reimbursement schedule.
