- Women with chronic HIV infection (WWH) living in the United States, experience a disproportionately high rate of obesity compared to uninfected populations. Both overweight and obesity, particularly central obesity, are major contributors to insulin resistance, hypertension, and dyslipidemia—the major components of metabolic syndromes, including type 2 diabetes, and leading to increased cardiovascular risk, including coronary heart disease, and cerebrovascular diseases. Notably, declining physical performance and frailty co-occur with vascular morbidities as well as changes in bone. These factors tend to exacerbate each other and accelerate the aging trajectory, leading to poorer quality of life, cognitive impairments, dementia, and eventually, death. In WWH, persistent HIV infection, sustained treatment for HIV infection, and concomitant obesity, may accelerate aging-related morbidities and poorer aging outcomes. Furthermore, health disparities factors common among some WWH, are independently associated with obesity and higher vascular risk. The purpose of this review is to describe the constellation of obesity, cardio- and cerebrovascular diseases, bone health and frailty among aging WWH, a 21st century emergence.

- Objectives: To evaluate the Swedish model for contact tracing and especiallythe "Västerbotten model" with centralised, extended contactinterview periods, sometimes by telephone.Methods: Using questionnaires, the contact tracing and interview procedurewas evaluated during 2002, followed by an evaluation of contactinterviewing by phone in 2005–6.Results: Patients with diagnosed Chlamydia trachomatis infection reportedon average 2.5 sexual contacts, 3.0 contacts when contact interviewingwas performed at the clinic, and 2.3 contacts when performedby phone. 65% of the sexual contacts with a known test resultwere infected.Conclusion: Centralised contact tracing, exploring the sexual history forat least 12 months back in time, shows good results. Combinedwith screening of certain risk groups it is probably one effectiveway of preventing C trachomatis infections. Preventing C trachomatisby primary prevention such as information and counselling is,however, still of great importance.

- Neonatal sepsis is common, lethal, and hard to diagnose. In combination with clinical findings and blood culture, biomarkers are crucial to make the correct diagnose. A Swedish national inquiry indicated that neonatologists were not quite satisfied with the available biomarkers. We assessed the kinetics of 15 biomarkers simultaneously: ferritin, fibrinogen, granulocyte colony-stimulating factor (G-CSF), interferon (IFN)-γ, interleukin (IL)-1β, −6, −8, −10, macrophage inflammatory protein (MIP)-1β, procalcitonin, resistin, serum amyloid A (SAA), tumor necrosis factor (TNF)-α, tissue plasminogen activator-3 and visfatin. The goal was to observe how quickly they rise in response to infection, and for how long they remain elevated. From a neonatal intensive care unit, newborns ≥28 weeks gestational age were recruited. Sixty-eight newborns were recruited to the study group (SG), and fifty-one to the control group (CG). The study group subjects were divided into three subgroups depending on clinical findings: confirmed sepsis (CSG), suspected sepsis (SSG) and no sepsis. CSG and SSG were also merged into an entire sepsis group (ESG) for sub-analysis. Blood samples were collected at three time-points; 0 h, 12–24 h and 48–72 h, in order to mimic a “clinical setting”. At 0 h, visfatin was elevated in SSG compared to CG; G-CSF, IFN-γ, IL-1β, −8 and − 10 were elevated in SSG and ESG compared to CG, whereas IL-6 and SAA were elevated in all groups compared to CG. At 12–24 h, IL-8 was elevated in ESG compared to CG, visfatin was elevated in ESG and SSG compared to CG, and SAA was elevated in all three groups compared to CG. At 48–72 h, fibrinogen was elevated in ESG compared to CG, IFN-γ and IL-1β were elevated in SSG and ESG compared to CG, whereas IL-8 and SAA were elevated in all three groups compared to CG. A function of time-formula is introduced as a tool for theoretical prediction of biomarker levels at any time-point. We conclude that SAA has the most favorable kinetics regarding diagnosing neonatal sepsis, of the biomarkers studied. It is also readily available methodologically, making it a prime candidate for clinical use.

- Purpose:The lack of available guidelines for the management of prostatic abscess (PA) results in inconsistencies in its management. The most commonly used management modalities were conservative treatment with parenteral antibiotics alone, transrectal ultrasound-guided (TRUS) needle aspiration, or transurethral deroofing (TUD).The current study is a retrospective study and examines prostatic abscess cases treated by either one or more of the different modalities. We assess and compare presentation, diagnosis, management, and outcomes of prostatic abscess and we compare the outcomes of the three management modalities.Methods:We retrieved the records of all patients (n = 23) admitted to the Urology department at Al Wakra hospital with the computed tomography (CT) diagnosis of prostatic abscess from January 2013 to March 2018. Data collected included demographic, clinical, laboratory, and imaging findings, as well as management modality, duration of hospital stay, duration of follow up, outcome, and recurrence.Results:A total of nine (39.1%) patients had conservative treatment only; eight (34.8%) had TUD, and six (26.1%) had TRUS needle aspiration. The mean age was 52.7 years. Lower urinary tract symptoms and fever were the most common presentations (95.7% and 82.6%, respectively). CT scan of the abdomen and pelvis with contrast was undertaken for all patients and it showed that multiple abscesses were observed in 14 (60.9%) cases.The overall mean hospital stay was 8.45 days (range 2–21 days). We observed no recurrences for patients treated conservatively or those who undertook TUD, but three patient (50%) recurrences were noted in TRUS aspiration patients. There was no mortality across the sample.Conclusion:Early diagnosis of prostatic abscess and prompt management may have decreased the morbidity and mortality. Conservative management can succeed in subcentimeter abscesses but TUD is the definite therapy for large and multiloculated abscess. TRUS aspiration does have a role in treatment, but it has higher recurrence and longer hospital stay.

- Introduction: Bacteraemia is a first stage for patients risking conditions such as septic shock. The primary aim of this study is to describe factors in the early chain of care in bacteraemia, factors associated with increased chance of survival during the subsequent 28 days after admission to hospital. Furthermore, the long-term outcome was assessed. Methods: This study has a quantitative design based on data from Emergency Medical Services (EMS) and hospital records. Results: In all, 961 patients were included in the study. Of these patients, 13.5% died during the first 28 days. The EMS was more frequently used by non-survivors. Among patients who used the EMS, the suspicion of sepsis already on scene was more frequent in survivors. Similarly, EMS personnel noted the ESS code "fever, infection" more frequently for survivors upon arriving on scene. The delay time from call to the EMS and admission to hospital until start of antibiotics was similar in survivors and non-survivors. The five-year mortality rate was 50.8%. Five-year mortality was 62.6% among those who used the EMS and 29.5% among those who did not (p < 0.0001). Conclusion: This study shows that among patients with bacteraemia who used the EMS, an early suspicion of sepsis or fever/infection was associated with improved early survival whereas the delay time from call to the EMS and admission to hospital until start of treatment with antibiotics was not. 50.8% of all patients were dead after five years.

- We studied the seasonal fluctuation of norovirus and other enteric viruses in Cameroon. Two hundred participants aged between 1 and 69 years were prospectively followed up. Each participant provided monthly faecal samples over a 12-month period. A total of 2484 samples were tested using multiplex real-time PCR assay for the detection of norovirus, rotavirus and enterovirus. The effect of weather variables and risk factors were analysed by Pearson correlation and bivariate analysis. Overall, enterovirus was the most commonly detected virus (216% of specimens), followed by norovirus (39%) and rotavirus (04%). Norovirus and enterovirus were detected throughout the year with a peak of norovirus detection at the beginning of the rainy season and a significant alternation of circulation of norovirus genogroups from one month to the next. Age <5 years and consumption of tap water were risk factors for norovirus infection. Better understanding of factors influencing transmission and seasonality may provide insights into the relationship between physical environment and risk of infection for these viruses.

- Pneumococcal conjugated vaccines (PCVs) have shown protection against invasive pneumococcal disease by vaccine serotypes, but an increase in non-vaccine serotype disease has been observed. Type-specific effects on clinical manifestation need to be explored.Clinical data from 2096 adults and 192 children with invasive pneumococcal disease were correlated to pneumococcal molecular serotypes. Invasive disease potential for pneumococcal serotypes were calculated using 165 invasive and 550 carriage isolates from children.The invasive disease potential was lower for non-PCV13 compared to vaccine-type strains. Patients infected with non-PCV13 strains had more underlying diseases, were less likely to have pneumonia and, in adults, tended to have a higher mortality. Furthermore, patients infected with pneumococci belonging to clonal serotypes only expressing non-PCV13 capsules had a higher risk for septicaemia and mortality.PCV vaccination will probably lead to a decrease in invasive pneumococcal disease but an alteration in the clinical manifestation of invasive pneumococcal disease. Genetic lineages causing invasive pneumococcal disease in adults often express non-vaccine serotypes, which can expand after vaccination with an increased risk of infection in patients with underlying diseases.

Is routine preoperative esophagogastroduodenscopy prior to bariatric surgery mandatory? : Protocol for a systematic review and meta-analysis
- 2020

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Routine preoperative esophagogastroduodenscopy (p-EGD) prior to bariatric surgery (BS) is currently widely undertaken, and hence an important issue with many clinical and financial repercussions. Yet, the true extent of why p-EGD is routinely undertaken for all bariatric patients remains not well understood. Methods and analysis: To address this, we will undertake a systematic review and meta-analysis of routine p-EGD prior to BS from around the world. This protocol describes the methodological approach to be adopted and outlines the search strategies and eligibility criteria that will be employed to identify and select studies, and the way by which data from the selected studies will be extracted for analysis. PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), WHO International Clinical Trials Registry Platform, Cochrane Library, MEDLINE, Scopus, clinicaltrials.gov and Google scholar will be searched from 01 January 2000 to 30 April 2019 for original studies written in English that provided prevalence estimates of the outcomes of routine p-EGD prior to BS. STROBE criteria will assess the methodological quality of the selected studies. The use of fixed or random effects model will depend on the results of statistical tests for heterogeneity. Publication bias will be visually estimated by assessing funnel plots. Pooled estimates will be calculated. This protocol conforms to the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines and has been submitted for registration at the PROSPERO International Prospective Register of systematic reviews. No ethical clearance is required for this study. This review will be published in a peer- reviewed journal and will be presented at various national and international conferences. © 2020 The Author(s)

- BACKGROUND: Infections have been hypothesised to increase the risk of dementia. Existing studies have included a narrow range of infectious diseases, relied on short follow-up periods, and provided little evidence for whether the increased risk is limited to specific dementia subtypes or attributable to specific microbes rather than infection burden. We aimed to compare the risk of Alzheimer's disease and other dementias across a wide range of hospital-treated bacterial and viral infections in two large cohorts with long follow-up periods.METHODS: In this large, multicohort, observational study, the analysis was based on a primary cohort consisting of pooled individual-level data from three prospective cohort studies in Finland (the Finnish Public Sector study, the Health and Social Support study, and the Still Working study) and an independent replication cohort from the UK Biobank. Community-dwelling adults (≥18 years) with no dementia at study entry were included. Follow-up was until Dec 31, 2012, in the Health and Social Support study, Dec 31, 2016, in the public sector study and the Still Working study, and Feb 7, 2018, in the replication cohort. Through record linkage to national hospital inpatient registers, we ascertained exposure to 925 infectious diseases (using the International Classification of Diseases 10th Revision codes) before dementia onset, and identified incident dementia from hospital records, medication reimbursement entitlements, and death certificates. Hazard ratios (HRs) for the associations of each infectious disease or disease group (index infection) with incident dementia were assessed by use of Cox proportional hazards models. We then repeated the analysis after excluding incident dementia cases that occurred during the first 10 years after initial hospitalisation due to the index infection.FINDINGS: From March 1, 1986, to Jan 1, 2005, 260 490 people were included in the primary cohort, and from Dec 19, 2006, to Oct 1, 2010, 485 708 people were included in the replication cohort. In the primary cohort analysis based on 3 947 046 person-years at risk (median follow-up 15·4 years [IQR 9·8-21·0]), 77 108 participants had at least one hospital-treated infection before dementia onset and 2768 developed dementia. Hospitalisation for any infectious disease was associated with increased dementia risk in the primary cohort (adjusted HR [aHR] 1·48 [95% CI 1·37-1·60]) and replication cohort (2·60 [2·38-2·83]). The association remained when analyses were restricted to new dementia cases that occurred more than 10 years after infection (aHR 1·22 [95% CI 1·09-1·36] in the primary cohort, the replication cohort had insufficient follow-up data for this analysis), and when comorbidities and other dementia risk factors were considered. There was evidence of a dose-response association between the number of episodes of hospital-treated infections and dementia risk in both cohorts (ptrend=0·0007). Although the greatest dementia risk was seen for central nervous system (CNS) infections versus no infection (aHR 3·01 [95% CI 2·07-4·37]), excess risk was also evident for extra-CNS infections (1·47 [1·36-1·59]). Although we found little difference in the infection-dementia association by type of infection, associations were stronger for vascular dementia than for Alzheimer's disease (aHR 2·09 [95% CI 1·59-2·75] versus aHR 1·20 [1·08-1·33] in the primary cohort and aHR 3·28 [2·65-4·04] versus aHR 1·80 [1·53-2·13] in the replication cohort).INTERPRETATION: Severe infections requiring hospital treatment are associated with long-term increased risk of dementia, including vascular dementia and Alzheimer's disease. This association is not limited to CNS infections, suggesting that systemic effects are sufficient to affect the brain. The absence of infection specificity combined with evidence of dose-response relationships between infectious disease burden and dementia risk support the hypothesis that increased dementia risk is driven by general inflammation rather than specific microbes.FUNDING: UK Medical Research Council, US National Institute on Aging, Wellcome Trust, NordForsk, Academy of Finland, and Helsinki Institute of Life Science.

Rare presentation of primary varicella zoster as fatal fulminant hepatitis in adult on low-dose, short-term steroid : Case report
- 2019

Ingår i: Annals of Medicine and Surgery. - : Elsevier. - 2049-0801. ; 48, s. 115-117
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Varicella zoster virus presents clinically as primary (chickenpox) or secondary (herpes zoster) infection. Cutaneous and extracutaneous dissemination may occur, usually in immunocompromised patients. VZV hepatitis that progresses to fulminant hepatic failure is very rare and fatal. To the best of our knowledge, 9 cases have been reported to date, of which 7 were in immunocompromised adults, and only one patient was on short duration steroid therapy. Presentation of case: We present a 26-year old man who was admitted initially with acute abdomen as query persistent biliary colic. Later, he showed clinical and laboratory findings of VZV hepatitis that progressed rapidly despite maximal medical ICU support and he expired on day 3 of admission. Conclusions: Acute VZV infection may present as fulminant hepatitis. The presentation may initially be challenging for the diagnosis and should be considered if the patient has been in contact with a sick case. Low dose corticosteroid could carry a risk for fatal VZV fulminant hepatitis and should be used very cautiously especially with VZV patients’ contacts. Further causative relationships remain to be established.
