Published: August 2020

Abstract
The XK field is a mature offshore asset with post peak production characterized by rapid oil decline rate and steep water cut. Many wells have ceased flow prematurely over time and non-rig interventions to reactivate and restore the wells to production had typically been ineffective owing to consistent low tubing head pressures and well construction/completions. Furthermore, the plan to initiate gaslift operations in the field was challenged by the lack of gaslift separator, compressor unit and gas line coupled with the fact that many of the wells were completed without gaslift mandrels. The deployment of innovative inter well gaslift, utilizing Gas Liquid Cylindrical Cyclone (GLCC) separator saved the situation and enabled achievement of the gaslift objective. The result was the successful restoration of three (3) long shut-in wells and associated increased oil production in the field.
This paper discusses the opportunities and challenges from inter well gaslift initiation and operations in XK field and the enormous potential as a low cost and efficient system for rejuvenating Brown Fields.

Abstract
BackgroundFrailty in older adults is a common multidimensional clinical entity, a state of vulnerability to stressors that increases the risk of adverse outcomes such as functional decline, institutionalization or death. The aim of this study is to identify the factors that anticipate the future inclusion of community-dwelling individuals aged ≥70 years in home care programmes (HC) and nursing homes (NH), and to develop the corresponding prediction models. MethodsA prospective cohort study was conducted in 23 primary healthcare centers located in Catalonia, Spain, with an eight-year follow-up (2005-2013). The cohort was made up of 616 individuals. Data collection included a baseline multidimensional assessment carried out by primary health care professionals. Outcome variables were collected during follow-up by consulting electronic healthcare records, and the Central Registry of Catalonia for mortality. A prognostic index for a HC and NH at eight years was estimated for each patient. Death prior to these events was considered a competing risk event, and Fine–Gray regression models were used. Results At baseline, mean age was 76.4 years and 55.5% were women. During follow-up, 19.2% entered a HC program, 8.2% a NH, and 15.4% died without presenting an event. Of those who entered a NH, 31.5% had previously been in a HC program. Multivariate models for a HC and NH showed that the risk of a HC entry was associated with older age, dependence on the Instrumental Activities of Daily Living, and slow gait measured by Timed-up-and-go test. An increased risk of being admitted to a NH was associated with older age, dependence on the Instrumental Activities of Daily Living, number of prescriptions, and the presence of social risk.ConclusionsPrognostic models based on comprehensive geriatric assessments can predict the need for the commencement of HC and NH admission in community-dwelling older adults. Our findings underline the necessity to measure functional capacity, mobility, number of prescriptions, and social aspects of older adults in primary healthcare centers. In such a setting they can be offered longitudinal holistic assessments so as to benefit from preventive actions in order to remain independent in the community for as long as possible.

Abstract
Background: Little is known about the intensity of multi-component initiatives (MCI) inclusive of any combination of programs, practices, policies, and environmental changes (P3E) on youth behaviors. Methods: The Healthy Schools Healthy Communities (HSHC) initiative worked to increase access to PA opportunities as part of 33 MCIs targeting school districts and respective communities. The purpose of this study was to assess whether MCIs with higher scoring PA-related strategies were associated with improved PA and sedentary behaviors among youth. PA-related interventions were assigned point values based on three characteristics: 1) purpose of initiative); 2) duration; and 3) reach. An overall composite score of all activities was calculated for each school district. Multivariate longitudinal regressions were applied, controlling for measurement period, Cohort, and district enrollment. Results: P3E scores ranged from 0.3 to 3.0 with 20% considered “higher-scoring” (score > 2.1) and 47% considered “lower-scoring” ( < 1.2 ). Average composite district P3E scores more than tripled over the evaluation period, rising from 14.8 in the first grant year to 32.1 in year 2, 41.1 in year 3, and 48.1 in year 4. For each additional point increase in average composite district P3E intensity score, the number of days per week that students reported being physically active for at least 60 minutes increased by 0.010 (p<0.01). For each additional point increase in district P3E intensity score, the number of hours per weekday that students reported engaging in screen time activities decreased by 0.006 hours (p<0.5). Conclusions: MCIs are difficult to evaluate given the variations within which they are implemented. Findings from this study suggest the value of a systematic scoring approach in assessing MCIs. In addition to tracking intensity over time, scoring can provide justification for, or against, an individual activity and ways to increase the likelihood of the MCI impacting population-health outcomes.
Reablement through time and space: A scoping review of how the concept of ‘reablement’ for older people has been defined and operationalised

Published: August 2020

Abstract
Background : While the field of rehabilitation has determined a common definition of professional practice, legislators and healthcare professionals in various Western countries have struggled to reach consensus about how the newer offer of ‘reablement’ should be organised, operationalised, and understood as a health service for older adults. International research indicates that there is confusion, ambiguity, and disagreement about the terminology and the structure of these programmes, and they may not be adequately supporting older people’s self-identified goals. Could an analysis of the concept’s genealogy illuminate how reablement can be more effective and beneficial in theory and in practice?
Methods : We conducted a qualitative and quantitative scoping review to determine how reablement has developed through time and space. Eligible articles ( n=86 ) had to focus on any of the defined features of current reablement programmes; there were no restrictions on study designs or publication dates. In articles published from 1947–2019, we identified themes and patterns, commonalities, and differences in how various countries described and defined reablement. We also performed an analysis using computer software to construct and visualise term maps based on significant words extracted from the article abstracts.
Results : The fundamental principles of reablement have a long history. However, these programmes have undergone a widespread expansion since the mid-2000s with an intention to reduce costs related to providing long-term care services and in-home assistance to growing older populations. Despite theoretical aspirations to offer person-centred and goal-directed reablement, very few countries have been able to implement programmes that adequately promote older people’s goals, social involvement, or participation in their local community in a safe, culturally sensitive and adaptable way.
Conclusions : Reablement is meant to support older people in attaining their self-defined goals to be both more physically independent at home and socially involved in their communities. However, until legislators, health professionals, and older people can collectively reach consensus about how person-centred reablement can be more effectively implemented and supported in professional homecare practice, it will be difficult to determine a conceptual description of reablement as a service that is unique, separate, and distinct from standard rehabilitation.

Abstract
Background The dolphinfish, Coryphaena hippurus , is a fast-swimming, predatory fish exhibiting relatively fast growth and early maturation among marine teleosts. It is an important, potentially renewable resource throughout its global subtropical-to-tropical range. Understanding the ecology of this wide-ranging fish is critical to proper fisheries management, but studies have historically depended heavily upon aggregated catch data reported by fisheries. This study uses tagging data to explore finer scale dolphinfish movements in two subregions of the Eastern Pacific Ocean (EPO) – the west coasts of Baja California Peninsula (WBC) and Oaxaca (OAX), Mexico. Results Adult dolphinfish (fork length 66 cm - 129 cm) were tagged with conventional (n = 132 tags) and electronic tags (n = 30 tags, miniPAT) between 2010 and 2014. Recapture rate of conventional tags was 4.5% with a maximum days of liberty of 141 days (mean = 56 d); twenty electronic tags reported but all did so prior to programmed release dates, with days at liberty ranging from 4 to 62 (mean = 24 d). Fish remained within the region they were tagged except for six fish tagged in WBC and one in OAX. Latitudinal (WBC) and longitudinal (OAX) extensions of observed fish movements (determined via a novel analytical approach) increased with days at liberty. Despite occasional deep dives (max 262 m), fish remained surface oriented with short excursions below the isothermal layer but larger OAX fish (fork length [103 cm, 120 cm]) inhabiting warmer waters (sea surface temperatures (SST) > ~26 °C) spent more time below the isothermal layer than smaller fish (fork length [90 cm,112 cm]) inhabiting colder WBC surface waters (SST > ~22 °C).Conclusions This study reveals movements of dolphinfish that infer regional differences in thermal habitat utilization and displacement over time. This inference evokes questions important to fisheries management regarding the three-dimensional extent of the dolphinfish’s realized thermal niche, its population structure, and the spatiotemporal connectivity of its habitats within the multinational EPO. With improved tag retention, longer deployments should capture increasing displacements along observed axes (N/S vs. E/W); the orientation of seasonal displacement axes suggest longer-distance movements would provide opportunities for reproductive mixing via trans-national migrations.

Abstract
Background: Nowadays, Ehrlichia canis receives increasing attention because of its great morbidity and mortality in animals. Dogs in the subclinical and chronic phases can be asymptomatic, and serologic tests show cross-reactivity and fail to differentiate between current and past infections. Moreover, there could be low parasitaemia, and E. canis might be found only in target organs, hence causing results to be negative by polymerase chain reaction (PCR) on blood samples.Methods: We evaluated by PCR the prevalence of E. canis in blood, liver, spleen, lymph node and bone marrow of 59 recently euthanised dogs that had ticks but were clinically healthy.Results: In total, 52.55% of the blood PCRs for E. canis were negative, yet 61.30% yielded positive results from tissue biopsies and were as follows: 63.15% from bone marrow, 52.63% from liver, 47.36% from spleen and 15.78% from lymph node. In addition, 33% had infection in three tissues (spleen, liver and bone marrow).Conclusions: Our results show the prevalence of E. canis from tissues of dogs that were negative by blood PCR. E. canis DNA in tissue was 30% lower in dogs that tested negative in PCR of blood samples compared to those that were positive. However, it must be taken into account that some dogs with negative results were positive for E. canis in other tissues.

Abstract
Background: We aimed to explore the utility of prostate specific antigen (PSA) isoform [-2]proPSA and its derivatives for prediction of pathological outcome after radical prostatectomy (RP).Methods: Preoperative blood samples were prospectively and consecutively analyzed from 472 patients treated with RP for clinically localized prostate cancer at four medical centers. Measured parameters were PSA, free PSA (fPSA), fPSA/PSA ratio, [-2]proPSA (p2PSA), p2PSA/fPSA ratio and Prostate Health Index (PHI) (p2PSA/fPSA)*√PSA]. Logistic regression models were fitted to determine the accuracy of markers for prediction of pathological Gleason score (GS) ≥7, Gleason score upgrading, extracapsular extension of the tumor (pT3) and the presence of positive surgical margin (PSM). Results: Of 472 patients undergoing RP, 339 (72%) were found to have pathologic GS ≥ 7, out of them 178 (53%) experienced an upgrade from their preoperative GS=6. The findings of pT3 and PSM were present in 132 (28%) and 133 (28%) cases, respectively. At univariable analysis of all the preoperative parameters, PHI was the most accurate predictor of pathological GS ≥7, GS upgrading, pT3 disease and the presence of PSM. Adding of PHI into the base multivariable model increased significantly the accuracy for prediction of pathological GS and GS upgrading by 4.4% (p=0.015) and 5.0% (p=0.025), respectively. Conclusion: We found that PHI provides the highest accuracy in predicting prostate cancer aggressiveness and expansion of the tumor detected at final pathology. The ability of PHI to predict the risk of Gleason score upgrade may help to identify potentially high-risk patients among men with biopsy proven insignificant prostate cancer.

Abstract
Background The development of child psychiatric services in China has been slow and very limited resources have been allocated to support its growth. This study set out to investigate the child and adolescent inpatient psychiatric resources currently available in top-tier psychiatric hospitals in China and the characteristics of youth patients hospitalized on an adult unit. Method As part of a official national survey, 29 most representative provincial tertiary psychiatric hospitals in China were selected. Data of 1975 inpatients discharged from these hospitals from March 19 to 31, 2019 were retrieved and analyzed. Results The mean number of youth psychiatric beds was 27.7±22.9 in these hospitals and 6/29 hospitals had no youth beds. There were significantly more youth beds in developed regions than in less developed regions (P<0.05). Most of discharged youth patients were teenagers with severe mental illnesses, including schizophrenia, depressive disorder and bipolar disorder. 7.5% (149) of 1975 discharged patients were youth while youth beds only accounted for 3.2% (804/25136) of all psychiatric beds. 45.6% (68) of youth patients were discharged from adult psychiatric units. Conclusion Our findings highlight the lack of adequate youth psychiatric inpatient services for children and adolescents living in China, especially in less developed regions. There is an urgent need to build more child and adolescent psychiatric units in provinces where there are none, and to increase the number of beds within the units that exist presently.

Abstract
Background: Syria has experienced war since 2011, leaving over 80% under the poverty line and millions being displaced. War and its retaliations have significantly impacted the mental health of Syrians. This study evaluates the post-traumatic stress disorder (PTSD), and the severity of the mental distress caused by war and other factors such as low social support. This study also evaluates other variables and compare the findings with multiple studies of Syria and refugees. Methods: This is a cross-sectional study that included people who lived in Syria from different provinces. Online surveys on multiple online groups included Kessler 10 (K10) questionnaire, the Screen for Posttraumatic Stress Symptoms (SPTSS) tool, the Multidimensional Scale of Perceived Social Support, and demographic and war-related questionnaires. Results: Our study included 1951 participants, of which, 527 (27.0%) were males and 1538 (78.8%) aged (19-25) years. Among participants, 44% had severe mental disorder, 27% had both severe mental disorder and full PTSD symptoms, 36.9% had full PTSD symptoms, and only 10.8% had neither positive PTSD symptoms nor mental disorder on the K10 scale. Around 23% had low overall support. Half of the responders were internally displaced, and 27.6% were forced to change place of living three times or more due to war. Around 86.6% of the responders believed that the crisis was the main reason for their mental distress. Those with high SPTSS and K10 scores were found to take more days off from work or school due to negative feelings and having somatic symptoms. Moreover, the number of times changing places of living due to war, educational level, and being distressed by war noise were the most important factors for more sever PTSD and mental distress. No differences in PTSD and mental disorder prevalence was noted between provinces or type of job. A strong correlation (r=0.623) was found between SPTSS and K10 scores. Conclusion: The conflict in Syria has left the population at a great risk for mental distress which was more severe compared to Syrian refugees elsewhere. Many measures with an emphasis on mental health are needed to aid the people against a long-term avoidable suffering.
Racial and ethnic patterns and differences in health care expenditures among Medicare beneficiaries with and without cognitive deficits or Alzheimer's disease and related dementias
Authors: Park Sungchul , Chen Jie 
Published: August 2020

Abstract
Background: Numerous studies have documented racial and ethnic differences in the prevalence and incidence of Alzheimer's disease and related dementias (ADRD). Less is known, however, about racial and ethnic differences in health care expenditures among older adults at risk for ADRD (cognitive deficits without ADRD) or with ADRD. In particular, there is limited evidence that racial and ethnic differences in health care expenditures change over the trajectory of ADRD or differ by types of service.Methods: We examined racial and ethnic patterns and differences in health care expenditures (total health care expenditures, out-of-pocket expenditures, and six service-specific expenditures) among Medicare beneficiaries without cognitive deficits, those with cognitive deficits without ADRD, and those with ADRD. Using the 1996-2017 Medical Expenditure Panel Survey, we performed multivariable regression models to estimate expenditure differences among racial and ethnic groups without cognitive deficits, those with cognitive deficits without ADRD, and those with ADRD. Models accounted for survey weights and adjusted for various demographic, socioeconomic, and health characteristics.Results: Asians and Latinos without cognitive deficits had lower total health care expenditures than whites without cognitive deficits ($10,236, $9,497, $9,597, and $11,541, respectively). There were no racial and ethnic differences in total health care expenditures among those with cognitive deficits without ADRD and those with ADRD. Across all three groups, however, blacks, Asians, and Latinos consistently had lower out-of-pocket expenditures than whites (except for Asians with cognitive deficits without ADRD). Furthermore, service-specific health care expenditures varied by racial and ethnic groups.Conclusions: Our study did not find significant racial and ethnic differences in total health care expenditures among Medicare beneficiaries with cognitive deficits and/or ADRD. However, we documented significant differences in out-of-pocket expenditures and service-specific expenditures. We speculated that the differences may be attributable to racial and ethnic differences in access to care and/or preferences based on family structure and cultural/economic factors. Particularly, heterogeneous patterns of service-specific expenditures by racial and ethnic groups underscore the importance of future research in identifying determinants leading to variations in service-specific expenditures among racial and ethnic groups.
