Abstract
Background
Inflammatory bowel disease (IBD) is increasing in the Asia-Pacific region, with changes in disease phenotype and course. We aimed to assess the changing phenotypes of IBD over ten years, describe the early clinical course (ECC) and identify the clinical predictors (CP) of poor outcomes among a large, multi-centre, cohort of Sri Lankan IBD patients.

Methods
We included patients [diagnosed between June/2003–December/2009-Group-1(G1), January/2010–June/2016-Group-2(G2)] with ulcerative colitis (UC) and Crohn disease (CD) from five national-referral centres. Changing phenotype from G1 to G2, ECC (disease duration < 3-years) and CP of poor outcomes (disease duration ≥ 1-year) was assessed. Poor outcomes were complicated-disease (CompD-stricturing/penetrating-CD, extensive-UC/pancolitis, perforation/bleeding/colectomy/malignancy) and treatment-refractory disease (TRD-frequently-relapsing, steroid-dependent/refractory and biologic use).

Results
375 (UC-227, CD-148) patients were recruited. Both G1/G2 had more UC than CD (77% vs 23%, 54.5 vs 45.5 respectively, p < 0.01). Increase of CD from G1-to-G2 was significant (23–45.4%, p < 0.001). In both groups, left-sided colitis (E2) and ileo-colonic (L3)/non-stricturing, non-penetrating disease behaviour (B1) CD predominated. Extensive-colitis (E3) (36.4% vs 22.7, p < 0.05) and stricturing-CD (B2) (26.1% vs 4.0%, p < 0.01) was commoner in G1. ECC was assessed in 173-patients (UC-94, CD-79). Aggressive disease behaviour and TRD were low among both UC and CD. Immunomodulator use was significantly higher among CD than UC (61.5% vs 29.0% respectively, p < 0.01). Anti-TNF use was low among both groups (UC-3.2%, CD-7.7%). Disease complications among UC [bleeding (2.1%), malignancy-(1.1%), surgery-(2.1%)] and CD [stricture-(3.9%), perforation-(1.3%), malignancy-(1.3%), surgery-(8.9%)] were generally low. CPs were assessed in 271-patients (UC-163, CD-108). Having a family history of IBD (for UC), extraintestinal manifestation (EIM), severe disease at presentation, being in younger age categories and severe disease at presentation, (for both UC and CD) predicted poor outcomes.

Conclusion
There was an increase in CD over time without change in disease phenotype for both UC and CD. A relatively benign ECC was observed. Family history (UC), EIMs (UC/CD), severe disease at presentation (UC/CD), younger age (CD/UC) CPs of poor outcomes.

AbstractBackgroundThe pathological conditions of UC and CD involved in inflammatory bowel disease-unclassified (IBD-U), UC with primary sclerosing cholangitis (PSC-UC), and UC with autoimmune pancreatitis type 2 (AIP-UC) remain unclear. Therefore, it is difficult to decide the appropriate treatments for these subtypes of UC. Our aim was to examine whether the discriminant equation using the mucosally expressed mediators designed as our previous study for IBD, could characterize IBD-U, PSC-UC, or AIP-UC.MethodsA total of 56 patients including UC (n = 24), CD (n = 15), IBD-U (n = 10), PSC-UC (n = 4), and AIP-UC (n = 3), along with 9 control patients were enrolled in this study. Mucosally expressed inflammatory mediators related to Th1, Th2, Th17, and Treg were measured using quantitative PCR in endoscopic biopsies from the inflamed intestines of the patients. The IBD-U, PSC-UC or AIP-UC were characterized using discriminant analysis and principle component analysis.ResultsThrough discriminant analyses, combinations of 3 to 7 inflammatory mediators were used to discriminate between UC and CD. Moreover, the identified 3 markers could diagnose patients with IBD-U as UC or CD with high accuracy. The distribution graph of inflammatory mediators using the principal component analysis revealed that PSC-UC and AIP-UC exhibited CD-like and UC-like features, respectively.ConclusionsThe discriminant equation using mucosally expressed mediators of IL-13, IL-21 and T-bet can be used as a universal diagnostic tool not only for IBD-U but also to assess pathological conditions in PSC-UC and AIP-UC.
Placing assistive technology and telecare in everyday practices of people with dementia and their caregivers: findings from an embedded ethnography of a national dementia trial

Published: February 2021

AbstractBackgroundPolicy makers and care providers see assistive technology and telecare as potential products to support people with dementia to live independently in their homes and communities. Previous research rarely examined how people with dementia and their caregivers actually use such technology. The study examined how and why people living with dementia and their caregivers used assistive technology and telecare in their own homes.MethodsThis study used an ethnographic design embedded within the NIHR-funded Assistive Technology and Telecare to maintain Independent Living At home for people with dementia (ATTILA) randomised controlled trial. We collected 208 h of observational data on situated practices of ten people with dementia and their ten caregivers. We used this data to construct extended cases to explain how technologies supported people with dementia in home and community settings.ResultsWe identified three themes: placing technology in care, which illustrates how people with dementia and caregivers ‘fit’ technology into their homes and routines; replacing care with technology, which shows how caregivers replaced normal care practices with ones mediated through technologies; and technology displacing care and everyday life, which highlights how technologies disrupted the everyday lives of people with dementia.DiscussionThis study exemplifies unintended and unanticipated consequences for assistive technology and telecare uptake in ‘real world’ community-based dementia care. It underlines the need to identify and map the context of technological provision over time within the changing lives of people with dementia and their caregivers.
Sociodemographic, health-related, and social predictors of subjective well-being among Chinese oldest-old: a national community-based cohort study
Authors: Cheng Gang , Yan Yan 
Published: February 2021

Abstract
Background
There is still a lack of systematic investigation of comprehensive contextual factors of subjective well-being (SWB) among Chinese oldest-old. This study aimed to explore sociodemographic, health-related, and social predictors of SWB among Chinese oldest-old using a large and representative sample.

Methods
The study included 49,069 individuals aged 80 and older from the Chinese Longitudinal Healthy Longevity Survey, a prospective, nationwide, community-based study conducted from 1998 to 2014. SWB was measured by eight items covering life satisfaction, positive affect (optimism, happiness, personal control, and conscientiousness), and negative affect (anxiety, loneliness, and uselessness). Generalized estimating equation models were used to explore the predictors of SWB.

Results
We found that age, gender, ethnic group, education, primary occupation before retirement, current marital status, and place of residence were sociodemographic predictors of SWB among the Chinese oldest-old. The health-related predictors included self-rated health, visual function, hearing function, diet quality, smoking status, drinking status, and exercise status. SWB was influenced by some social factors, such as the number of biological siblings, the number of children, leisure activities, financial independence, and access to adequate medical service. In particular, self-rated health, access to adequate medical services, exercise status, and place of residence exert a stronger effect than other factors.

Conclusions
SWB in the oldest-old is influenced by a large number of complex sociodemographic, health-related, and social factors. Special attention should be paid to the mental health of centenarians, women, rural residents, widowed, physically disabled, and childless oldest-old people. Relevant agencies can improve physical activities, leisure activities, financial support, and medical services to promote the well-being of the oldest-old.

Abstract
Background
Perinatally chikungunya infected neonates have been reported to have high rates of post-infection neurologic sequelae, mainly cognitive problems. In older children and adults chikungunya does not appear to have sequelae, but data on postnatally infected infants are lacking.

Methods
We performed a prospective, non-controlled, observational study of infants infected before the age of 6 months with a severe chikungunya infection during the 2014–2015 epidemic in Curaçao, Dutch Antilles. Two years post-infection cognitive and motor - (BSID-III) and social emotional assessments (ITSEA) were performed.

Results
Of twenty-two infected infants, two died and two were lost to follow up. Eighteen children were seen at follow-up and included in the current study. Of these, 13 (72%) had abnormal scores on the BSID-III (cognitive/motor) or ITSEA.

Conclusion
In the first study aimed at postnatally infected infants, using an uncontrolled design, we observed a very high percentage of developmental problems. Further studies are needed to assess causality, however until these data are available preventive measure during outbreaks should also include young infants. Those that have been infected in early infancy should receive follow up.
Pseudomonas aeruginosa device associated – healthcare associated infections and its multidrug resistance at intensive care unit of University Hospital: polish, 8.5-year, prospective, single-centre study

Published: February 2021

Abstract
Background
Pseudomonas aeruginosa has recently shown to be one of the most important strains of bacteria and alert pathogens in Europe among Intensive Care Unit patients that provide serious therapeutic problems because of its multidrug resistance.

Methods
The purpose of this microbiological study was data analysis of device associated- healthcare associated infections (DA-HAIs) in an ICU in terms of the incidents of P.aeruginosa strain infections and its susceptibility within an 8.5-year observation.

Results
Among 919 isolated strains responsible for 799 DA-HAIs (17,62 ± 1,98/1000 patient-days) in 4010 ICU patients P.aeruginosa was the pathogen in 108/799 (13.52%) cases. Incidence rate (density) of: VAP/1000 MV- days, UTI /1000 UC- days and CLA-BSI/1000 CL- days were 11,15 ± 2.5, 6.82 ± 0.81, 2.35 ± 1.54.respectivelly. P.aeruginosa was the pathogen most frequently responsible for VAP 69/108 (63.88%). Mean frequency of VAP, UTI and CLA-BSI with P.aeruginosa etiology was 69/493 (14.28%), 32/299 (11.1%) and 7/127 (5.77%) respectively. The mean density of P.aeruginosa infection amounted to 2.43/1000 patient-days. The decrease was observed in the total number of DA-HAIs caused by the P.aeruginosa from 15.75% and 3.23/1000 patient-days in 2011 to 5.0% and 1.17/1000 in 2016 (p = 0.0104, p = 0.0348). Starting from 2016 to 2019 incidence and density of P.aeruginosa DA-HAIs increased to 12.33% and 2.63/1000 (p = 0.1388, p = 0.0818). P.aeruginosa was susceptible to ceftazidime, cefepime, amikacin, meropenem, ciprofloxacin, colistin, in 55.55, 58.33, 70.37, 53.73, 50, and 100% respectively. MDR characterised it in 40% in 2011 and 66.7% in 2019, (p = 0.177).

Conclusions
The study revealed a changeable prevalence of P. aeruginosa strain infections; however their frequency was never highest in our ICU patients as it presented in the last years in Europe. The study showed a significant decrease in 2016 and increase in 2019, a nearly 3-fold increase of P.aeruginosa infections among Gram-negative strain infections, and a 2-fold increase of the P.aeruginosa DA-HAIs frequency between 2016 and 2019 as well as an increased resistance. Microbiological analysis of DA-HAIs in each hospital should be a standard method used in hospital infection control and antibiotic policy. In the case of P.aeruginosa, in order to minimize transmission, preventive infection methods should be assessed mainly in case of VAP.
A comparison of two multiplex-PCR assays for the diagnosis of traveller’s diarrhoea
Authors: Schaumburg Frieder , Froböse Neele , Köck Robin 
Published: February 2021

Abstract
Background
Numerous multiplex-PCR assays are now available in routine diagnostics but their clinical value is controversial if a clear association between clinical symptoms and the detection of a particular pathogen is missing. The objective of this work was to evaluate a multiplex-PCR assay for the diagnosis of traveller’s diarrhoea (TD) in a case-control study and to assess the concordance with the BioFire® FilmArray® Gastrointestinal Panel.

Methods
Stool samples from cases (n = 61) and controls (n = 30) were collected during travel and analysed by the GI-EB Screening assay (Seegene) in a case-control study. The concordance with the BioFire® FilmArray® Gastrointestinal Panel was expressed as the proportion of participants in which both tests agreed in the category “detected” and “not detected”.

Results
None of the test-target organisms (Campylobacter spp., Clostridioides difficile toxin A/B, Salmonella spp., Shigella spp./enteroinvasive Escherichia coli, E. coli O157, Shiga toxin-producing E. coli, Yersinia enterocolitica) was significantly associated with TD GI-EB Screening assay. The GI-EB Screening assay had an agreement with the BioFire® FilmArray® of 86.8–100%.

Conclusion
The selection of test-target organisms included in the GI-EB Screening assay appears inappropriate for the diagnostic work-up of TD as none of the detected pathogens was associated with TD. The GI-EB Screening assay had a good concordance with BioFire® FilmArray®.
An exploration of patient-provider dynamics and childbirth experiences in rural and urban Peru: a qualitative study

Published: February 2021

Abstract
Background
Between 2006 and 2013, Peru implemented national programs which drastically decreased rates of maternal and neonatal mortality. However, since 2013, maternal and neonatal mortality in Peru have increased. Additionally, discrimination, abuse, and violence against women persists globally and impacts birthing experiences and mental health. This qualitative study sought to better understand the attitudes and beliefs regarding childbirth among women and providers in Southern Peru. This study also explores how these beliefs influence utilization of skilled care, patient-provider dynamics, and childbirth experiences and identifies factors that impact providers’ provision of care.

Methods
Thirty semi-structured interviews were conducted with 15 participants from rural Colca Canyon and 15 participants from urban Arequipa between April and May 2018. In each region, 10 women who had experienced recent births and five providers were interviewed. Provider participants predominantly identified as female and were mostly midwives. All interviews were conducted, transcribed, and coded in Spanish. A framework analysis was followed, and data were charted into two separate thematic frameworks using contextual and evaluative categories of conceptualization of childbirth.

Results
All recent births discussed were facility-based births. Four domains emerged: women’s current birth experiences, provision of childbirth care, beliefs about childbirth among women and providers, and future health-seeking behavior. Findings suggest that women’s feelings of helplessness and frustration were exacerbated by their unmet desire for respectful maternity care and patient advocacy or companionship. Providers attributed strain to perceived patient characteristics and insufficient support, including resources and staff.

Conclusions
Our findings suggest current childbirth experiences placed strain on the patient-provider dynamic and influenced women’s attitudes and beliefs about future experiences. Currently, the technical quality of safe childbirth is the main driver of skilled birth attendance and facility-based births for women regardless of negative experiences. However, lack of respectful maternity care has been shown to have major long-term implications for women and subsequently, their children. This is one of the first studies to describe the nuances of patient-provider relationships and women’s childbirth experiences in rural and urban Peru.
Perceived differences on the role of traditional birth attendants in rural Tanzania: a qualitative study

Published: February 2021

Abstract
Background
In many low to middle income countries, traditional birth attendants (TBAs) play various roles (e.g., provision of health education, referral to hospitals, and delivery support) that can potentially improve women’s access to healthcare. In Tanzania, however, the formal healthcare systems have not acknowleded the role of the TBAs. TBAs’ contributions are limited and are not well described in policy documents. This study aimed to examine the perspectives of both TBAs and skilled birth attendants (SBAs) to clarify the role of TBAs and issues impacting their inclusion in rural Tanzania.

Methods
We used a qualitative descriptive design with triangulation of investigators, methods, and data sources. We conducted semi-structured interviews with 15 TBAs and focus group discussions with 21 SBAs in Kiswahili language to ask about TBAs’ activities and needs. The data obtained were recorded, transcribed, and translated into English. Two researchers conducted the content analysis.

Results
Content analysis of data from both groups revealed TBAs’ three primary roles: emergency delivery assistance, health education for the community, and referrals. Both TBAs and SBAs mentioned that one strength that the TBAs had was that they supported women based on the development of a close relationship with them. TBAs mentioned that, while they do not receive substantial remuneration, they experience joy/happiness in their role. SBAs indicated that TBAs sometimes did not refer women to the hospital for their own benefit. TBAs explained that the work issues they faced were mainly due to insufficient resources and unfavorable relationships with hospitals. SBAs were concerned that TBAs’ lacked formal medical training and their actions could interfere with SBAs’ professional work. Although there were no between-group interactions at the time of this study, both groups expressed willingness to collaborate/communicate to ensure the health and lives of mothers and babies.

Conclusions
TBAs and SBAs have different perceptions of TBAs’ knowledge and skills, but agreed that TBAs need further training/inclusion. Such collaboration could help build trust, improve positive birth experiences of mothers in rural Tanzania, and promote nationwide universal access to maternal healthcare.

AbstractBackgroundInasmuch as induced abortions, miscarriages and stillbirths constitute common adverse pregnancy outcomes contributing to poor maternal health, there is paucity of literature about these in Ghana. We investigated the factors associated with induced abortions, miscarriages and stillbirths in Ghana.MethodsData derived from the 2017 Ghana Maternal Health Survey was used in this study. Women aged 15–49 constituted the target for the study. This study examined the relationship between socio-demographic characteristics and induced abortions, stillbirths and miscarriages. Subsequently, multivariable binary logistic regression models were fitted to investigate the factors associated with induced abortions, stillbirths and miscarriages at 95 % confidence interval (CI).ResultsThe prevalence of miscarriages, induced abortions and stillbirths in Ghana in 2017 were 10.8 %, 10.4 % and 2 % respectively. Induced abortions (12.9 %) and miscarriages (11.1 %) were found to be higher among urban residents whiles rural residents had more of stillbirths (2.1 %). Compared to women aged 15–24, those in all age categories had lower odds of experiencing induced abortions, with the lowest odds occurring among women aged 35–49 (AOR = 0.26, 95 % CI = 0.21-32). Conversely, women of all age categories had higher odds of experiencing miscarriages compared to those aged 15–24 with the highest odds among those aged 25–34 (AOR = 1.62, 95 % CI = 1.39–1.89). Women with at least primary education were more likely to experience miscarriages than those with no formal education, with those with higher level of education having the highest odds (AOR = 1.42, 95 % CI = 1.13–1.78). While the likelihood of induced abortions was lower among Muslims, compared to Christians (AOR = 0.65, 95 % CI = 0.52–0.82), the odds of miscarriages were higher among Muslims, compared to Christians (AOR = 1.31, 95 % CI = 1.13–1.52). Women with parity 1 or more were less likely to experience induced abortions, miscarriages and stillbirths compared to those with parity 0.ConclusionsOur study indicates that efforts to limit induced abortions, miscarriages and stillbirths in Ghana need to focus on the disparities in socio-demographic characteristics of women. Synergy between government health institutions and the private sector cannot be left out if much success can be achieved in efforts to subside the current prevalence of induced abortions, stillbirths and miscarriages confronting the country.
