Published: March 2020

Abstract
Background
Hip fractures represent a global public health issue that demands high cost both from the patient and from the society. Functional exercise in the subacute phase of a hip fracture is essential in reducing these costs. To the best of our knowledge, no qualitative study has explored the patients’ experiences in participating in an exercise program during the first month after surgery. Thus, this study aims to explore how older people who had participated in an evidence-based exercise intervention describe their relationship with their therapists and how this relationship might contribute to their motivation for exercise.

Methods
Thirteen women and six men, who all had experienced a hip fracture and were staying in the same short-term rehabilitation unit, were interviewed by the last author. The interviews lasted from 30 to 70 min. The participants’ mean age was 86 years and they had all participated in a High Intensity Functional Exercise (HIFE) program in one-on-one sessions for 2 weeks, a total of 10 sessions. The recruitment was done by therapists involved in an RCT evaluating the HIFE-program with the attempt to obtain maximum variation. Data were analyzed through systematic text condensation in collaboration between all authors.

Results
The analysis yielded three main themes integrated in the core theme “Therapeutic alliance is an interpretative filter for the participants’ experiences.” The three themes were “The feeling of mutuality and respect in the alliance”; “A trusting and motivating relationship” and “Tailoring of the instruction and program to make the task understandable”. These themes concerned basic needs in the relationship between the participants and the therapists which brought forward a feeling of mutual respect. The most prominent finding was the experience of trust in the therapists’ abilities, and how this contributed to the participants’ motivation to fulfil the program and achieve meaningful changes.

Conclusion
Our findings suggest that therapeutic alliance is an indispensable aspect of a therapy, and relational knowledge and competence are prerequisites in the transfer of professional knowledge in a therapy. Our findings can be useful to therapists involved in clinical practice, especially to those working with vulnerable groups.

Published: March 2020

Abstract
Backgrounds
Little is known about the role of frailty in the recovery process of disability among older adults. We examined the association between frailty and recovery from activities of daily living (ADL) and instrumental ADL (IADL) disability among community-dwelling Chinese older adults.

Methods
Data were from the China Health and Retirement Longitudinal Study. Three waves were used. Participants ≥60 years, had frailty assessment at baseline, and had incident disability in ADL or IADL in 2013, and had disability assessment in 2015 were included. Recovery from ADL and IADL disability were used as outcome measure. Multivariable logistic regression was used to evaluate the potential association between frailty and recovery from ADL or IADL.

Results
We included 516 and 598 participants in the ADL and IADL analysis, respectively. In total, 237 participants recovered from ADL disability and 293 recovered from IADL disability. Nearly half of the non-frail persons recovered from ADL disability, while less than one-quarter of the frail persons had recovery. Over half of the non-frail persons had IADL disability recovery, while only 30% of the frail recovered. After adjustment, the odds of recovery from ADL disability were 59% (95% confidence interval [CI]: 1, 83%) lower among frail participants than those who were non-frail; the odds of recovery from IADL disability were 52% lower among frail persons than those who were non-frail and the association did not reach statistical significance.

Conclusions
Frailty is an independent predictor of poor recovery from disability among nondisabled community-dwelling older adults in China.
Gait speed, cognition and falls in people living with mild-to-moderate Alzheimer disease: data from NILVAD
Authors:   for the NILVAD Study Group, Dyer Adam H. , Lawlor Brian , Kennelly Sean P. 
Published: March 2020

Abstract
Background
Previous evidence suggests that slower gait speed is longitudinally associated with cognitive impairment, dementia and falls in older adults. Despite this, the longitudinal relationship between gait speed, cognition and falls in those with a diagnosis of dementia remains poorly explored. We sought to assess this longitudinal relationship in a cohort of older adults with mild to-moderate Alzheimer Disease (AD).

Methods
Analysis of data from NILVAD, an 18-month randomised-controlled trial of Nilvadipine in mild to moderate AD. We examined: (i) the cross-sectional (baseline) association between slow gait speed and cognitive function, (ii) the relationship between baseline slow gait speed and cognitive function at 18 months (Alzheimer Disease Assessment Scale, Cognitive Subsection: ADAS-Cog), (iii) the relationship between baseline cognitive function and incident slow gait speed at 18 months and finally (iv) the relationship of baseline slow gait speed and incident falls over the study period.

Results
Overall, one-tenth (10.03%, N = 37/369) of participants with mild-to-moderate AD met criteria for slow gait speed at baseline and a further 14.09% (N = 52/369) developed incident slow gait speed at 18 months. At baseline, there was a significant association between poorer cognition and slow gait speed (OR 1.05, 95% CI 1.01–1.09, p = 0.025). Whilst there was no association between baseline slow gait speed and change in ADAS-Cog score at 18 months, a greater cognitive severity at baseline predicted incident slow gait speed over 18 months (OR 1.04, 1.01–1.08, p = 0.011). Further, slow gait speed at baseline was associated with a significant risk of incident falls over the study period, which persisted after covariate adjustment (IRR 3.48, 2.05–5.92, p < 0.001).

Conclusions
Poorer baseline cognition was associated with both baseline and incident slow gait speed. Slow gait speed was associated with a significantly increased risk of falls over the study period. Our study adds further evidence to the complex relationship between gait and cognition in this vulnerable group and highlights increased falls risk in older adults with AD and slow gait speed.

Published: March 2020

AbstractBackgroundThe aims of this study were to (1) evaluate the efficacy and safety of targeted antibiotics for the treatment of culture-negative prosthetic joint infection based on metagenomic next-generation sequencing results and (2) verify the accuracy and reliability of metagenomic next-generation sequencing for identifying pathogens related to culture-negative prosthetic joint infection.MethodsNinety-seven consecutive PJI patients, including 27 patients with culture-negative prosthetic joint infection, were treated surgically at our center. Thirteen of the 27 culture-negative prosthetic joint infection patients, who were admitted before June 2017 and treated with empirical antibiotics, comprised the empirical antibiotic group (EA group), and the other 14 patients, who were admitted after June 2017 and treated with targeted antibiotics according to their metagenomic next-generation sequencing results, were classified as the targeted antibiotic group (TA group). The short-term infection control rate, incidence of antibiotic-related complications and costs were compared between the two groups.ResultsTwo of the patients in the EA group experienced debridement and prolonged antimicrobial therapy due to wound infection after the initial revision surgery. No recurrent infections were observed in the TA group; however, no significant difference in the infection control rate was found between the two groups (83.33% vs 100%,P = 0.217). More cases of antibiotic-related complications were recorded in the EA group (6 cases) than in the TA group (1 case), but the difference was not statistically significant (P = 0.0697). The cost of antibiotics obtained for the EA group was 20,168.37 Yuan (3236.38–45,297.16), which was higher than that found for the TA group (10,164.16 Yuan, 2959.54–16,661.04,P = 0.04).ConclusionsTargeted antibiotic treatment for culture-negative prosthetic joint infection based on metagenomic next-generation sequencing results is associated with a favorable outcome, and metagenomic next-generation sequencing is a reliable tool for identifying pathogens related to culture-negative prosthetic joint infection.

Abstract
Background
Cryptosporidium sp. are common intracellular parasites responsible of severe diarrhea in T-cell-immunocompromised patients. We report the first case of a woman who contracted cryptosporidiosis after treatment with fingolimod, a drug labeled for multiple sclerosis and responsible for marked lymphopenia.

Case presentation
A 60-year-old woman was admitted for abdominal pain diarrhea and fever. The patient suffered from multiple sclerosis and had been treated with fingolimod from august 2017 to september 2018 time of occurrence of the first digestive symptoms. Stool culture was negative but parasitological examination was positive for Cryptosporidium sp. Blood biological examination profound lymphopenia of 240/mm3 [17 CD4/mm3 (7%) and 32 CD8/mm3 (14%)]. Fingolimod was stopped, and the patient was put on nitazoxanide 500 mg bid for 7 days. The diarrhea resolved and no relapse was observed. Six other cases were found in the Pharmacovigilance database.

Conclusion
Physicians should be aware of this association and screen for Cryptosporidium in cases of diarrhea in patients treated with fingolimod. Patients should be aware of this risk and advise to take appropriate measures to avoid such contamination.

Published: March 2020

Abstract
Background
The objective of our study was to evaluate the association between perinatal asphyxia and hypoxic-ischemic encephalopathy (HIE) with the presence of ante and intrapartum risk factors and/or abnormal fetal heart rate (FHR) findings, in order to improve maternal and neonatal management.

Methods
We did a prospective observational cohort study from a network of four hospitals (one Hub center with neonatal intensive care unit and three level I Spoke centers) between 2014 and 2016. Neonates of gestational age ≥ 35 weeks, birthweight ≥1800 g, without lethal malformations were included if diagnosed with perinatal asphyxia, defined as pH ≤7.0 or Base Excess (BE) ≤ − 12 mMol/L in Umbical Artery (UA) or within 1 h, 10 min Apgar < 5, or need for resuscitation > 10 min.
FHR monitoring was classified in three categories according to the American College of Obstetricians and Gynecologists (ACOG). Pregnancies were divided into four classes: 1) low risk; 2) antepartum risk; 3) intrapartum risk; 4) and both ante and intrapartum risk.
In the first six hours of life asphyxiated neonates were evaluated using the Thomson score (TS): if TS ≥ 5 neonates were transferred to Hub for further assessment; if TS ≥ 7 hypothermia was indicated.

Results
Perinatal asphyxia occurred in 21.5‰ cases (321/14,896) and HIE in 1.1‰ (16/14,896). The total study population was composed of 281 asphyxiated neonates: 68/5152 (1.3%) born at Hub and 213/9744 (2.2%) at Spokes (p < 0.001, OR 0.59, 95% CI 0.45–0.79). 32/213 (15%) neonates were transferred from Spokes to Hub. Overall, 12/281 were treated with hypothermia. HIE occurred in 16/281 (5.7%) neonates: four grade I, eight grade II and four grade III. Incidence of HIE was not different between Hub and Spokes.
Pregnancies resulting in asphyxiated neonates were classified as class 1) 1.1%, 2) 52.3%, 3) 3.2%, and 4) 43.4%. Sentinel events occurred in 23.5% of the cases and FHR was category II or III in 50.5% of the cases. 40.2% cases of asphyxia and 18.8% cases of HIE were not preceded by sentinel events or abnormal FHR.

Conclusions
We identified at least one risk factor associated with all cases of HIE and with most cases of perinatal asphyxia. In absence of risk factors, the probability of developing perinatal asphyxia resulted extremely low. FHR monitoring alone is not a reliable tool for detecting the probability of eventual asphyxia.
Risk factors during pregnancy and delivery for the development of Perthes’ disease, a nationwide Swedish study of 2.1 million individuals
Authors: Lindblad Maria , Josefsson Ann , Bladh Marie , Sydsjö Gunilla , Johansson Torsten 
Published: March 2020

Abstract
Background
To ascertain or disprove a correlation between suboptimal birth characteristics, breech position at delivery and development of Perthes’ disease.

Methods
Study material was collected from nationwide registers regarding diagnoses, birth statistics and delivery data. As study population were included children with a diagnosis code for Perthes’ disease who were alive and living in Sweden at age 13. Children with missing birth statistics were excluded. All children with no Perthes’ disease diagnosis were used as control group. Both single and multiple logistical regression analyses were used to calculate OR for the included characteristics.

Results
Children in breech position had a higher risk for developing Perthes’ disease. Children with Perthes’ disease had also a higher probability of having been born pre-term, very pre-term or post-term. Lower than normal birth weight and a lower Apgar-score were also associated with Perthes’ disease.

Conclusions
There is a correlation between breech birth and development of Perthes’ disease. There is also correlation to suboptimal birth characteristics. Despite our findings this should not be used for screening of Perthes’ disease as the percentage of children who actually develop it is very low. Also, as of yet there is no possibility to diagnose Perthes’ disease before the presence of skeletal changes. Our findings could be important in finding the cause of Perthes’ disease and therefore developing better diagnostics, treatment and prevention.

Published: March 2020

Abstract
Background
Li-Fraumeni syndrome is a cancer predisposition syndrome caused by germline TP53 tumor suppressor gene mutations, with no previous association with pancreatic neuroendocrine tumors (PNETs). Here we present the first case of PNET associated with Li-Fraumeni syndrome.

Case presentation
This is a 43-year-old female who underwent laparoscopic distal pancreatectomy at age 39 for a well-differentiated grade 2 cystic PNET. When the patient was 41 years old, her seven-year-old daughter was found to have an astrocytoma and a germline TP53 mutation. While undergoing surveillance with 68Gallium-DOTATATE positron emission tomography/computed tomography for her PNET, the patient was found to have a large choroid plexus papilloma in her right temporal lobe. She underwent genetic counseling and testing that identified a germline pathogenic variant in TP53, leading to the diagnosis of Li-Fraumeni syndrome. Her PNET had a hemizygous pathogenic TP53 mutation with loss of the wild-type alternate allele, consistent with loss of heterozygosity and the two-hit hypothesis. She was enrolled in a Li-Fraumeni syndrome protocol and continues surveillance screening with our service.

Conclusions
This is the first PNET reported in association with Li-Fraumeni syndrome. Pancreatic cancer risk is elevated in this syndrome, and our case highlights the need for vigilance in screening for pancreatic neoplasms in these patients.
In silico analysis of the immune microenvironment in bladder cancer
Authors: Zhang Ye , Ou De-hua , Zhuang Dong-wu , Zheng Ze-feng , Lin Ming-en 
Published: March 2020

Abstract
Background
Infiltrating immune and stromal cells are vital components of the bladder cancer (BC) microenvironment, which can significantly affect BC progression and outcome. However, the contribution of each subset of tumour-infiltrating immune cells is unclear. The objective of this study was to perform cell phenotyping and transcriptional profiling of the tumour immune microenvironment and analyse the association of distinct cell subsets and genes with BC prognosis.

Methods
Clinical data of 412 patients with BC and 433 transcription files for normal and cancer tissues were downloaded from The Cancer Genome Atlas. The CIBERSORT algorithm was used to determine the relative abundance of 22 immune cell types in each sample and the ESTIMATE algorithm was used to identify differentially expressed genes within the tumour microenvironment of BC, which were subjected to functional enrichment and protein-protein interaction (PPI) analyses. The association of cell subsets and differentially expressed genes with patient survival and clinical parameters was examined by Cox regression analysis and the Kaplan-Meier method.

Results
Resting natural killer cells and activated memory CD4+ and CD8+ T cells were associated with favourable patient outcome, whereas resting memory CD4+ T cells were associated with poor outcome. Differential expression analysis revealed 1334 genes influencing both immune and stromal cell scores; of them, 97 were predictive of overall survival in patients with BC. Among the top 10 statistically significant hub genes in the PPI network, CXCL12, FN1, LCK, and CXCR4 were found to be associated with BC prognosis.

Conclusion
Tumour-infiltrating immune cells and cancer microenvironment-related genes can affect the outcomes of patients and are likely to be important determinants of both prognosis and response to immunotherapy in BC.
CD8-positive memory T cells in tumor-draining lymph nodes of patients with breast cancer

Published: March 2020

Abstract
Background
Human immunological memory is a hallmark of the adaptive immune system and plays an important role in the development of effective immune responses against tumors. In the present study, we aimed to determine the frequencies of CD8+ memory T cell subsets including T stem cell memory (TSCM) in tumor-draining lymph nodes of patients with breast cancer (BC).

Methods
Mononuclear cells were obtained from axillary lymph nodes of 52 untreated patients with BC and stained for CD8, CCR7, CD45RO, CD95 markers to detect different subtypes of memory cells in the CD8+ lymphocyte population. Data were acquired on four-color flow cytometer and analyzed with CellQuest Pro software.

Results
We observed that 47.65 ± 2.66% of CD8+ lymphocytes expressed the CD45RO, a marker for memory T cells. Statistical analysis showed that the total frequency of central memory T cells (TCM) and their subset with low CD45RO expression was significantly higher in tumor-involved nodes compared to tumor-free ones (P = 0.024 and P = 0.017, respectively). The level of CD95 expression (based on mean fluorescence intensity) on the surface of TCM, their CD45ROhi and CD45ROlow subsets, and TSCM was higher in patients with stage II compared to those in stage I (P < 0.05). In addition, the percentage of naive CD8+ T cells was significantly lower in tumor-involved lymph nodes compared to tumor-free ones (P = 0.025).

Conclusions
Our data collectively indicate no significant differences in the frequencies of CD8+ lymphocytes or their memory subsets in tumor-draining lymph nodes of patients with BC. However, the frequency of CD45low TCM was higher in tumor-involved nodes. Along with a decrease in the frequency of naive T cells, the higher frequency of CD45low TCM suggests that despite the immune reaction to provide a pool of effective memory cells, it is blocked in early-stage of memory cells’ differentiation (CD45ROlow), probably by tumor-derived suppressive factors. Identifying the molecular and cellular mechanisms behind this suppression can provide invaluable tools for adoptive T cell therapies in cancer.
Actor and partner effects of parenting stress and co-parenting on marital conflict among parents of children with atopic dermatitis
Authors: Han Jeong Won , Lee Hanna 
Published: March 2020

Abstract
Background
It is important for healthcare providers to pay attention to parents’ rearing style and children’s physical symptoms to promote a healthy quality of life among children with atopic dermatitis. We aimed to identify effects of parenting stress and co-parenting on marital conflict among parents of children with atopic dermatitis.

Methods
Participants were 161 fathers and 161 mothers raising seven-year-old children treated for atopic dermatitis. To confirm the effects of parenting stress and co-parenting on marital conflict, the “actor-partner interdependence mediation model” was used. To verify goodness-of-fit, maximum likelihood method was used, and a confirmatory factor analysis was conducted to confirm the validity of latent variables for model analysis.

Results
Fathers’ parenting stress had actor (β = −.46, p < .001) and partner (β = −.22, p < .001) effects on co-parenting, and mothers’ parenting stress had actor (β = −.20, p < .001) and partner (β = −.36, p < .001) effects on co-parenting. Fathers’ parenting stress only had an actor effect on marital conflict (β = .32, p < .001). Father’s co-parenting had actor (β = −.29, p < .001) and partner (β = −.22, p < .001) effects on marital conflict, and mothers’ co-parenting had actor (β = −.39, p < .001) and partner (β = −.19, p < .001) effects on marital conflict. There were significant differences between the two groups concerning three path coefficients: fathers’ parenting stress affected fathers’ marital conflict, fathers’ co-parenting affected fathers’ marital conflict, and mothers’ co-parenting affected fathers’ marital conflict.

Conclusions
It is vital for healthcare providers to seek ways to reduce the marital conflicts of parents of children with atopic dermatitis, including further examination of the role of co-parenting, to address children’s physical symptoms and promote their health. Our findings inform management and intervention programs for the families of children with atopic dermatitis.
