Published: April 2021

Abstract
Objective
The occurrence of osteoarthritis is related to genetic and environmental factors. Among them, the change of chondrocyte gene expression pattern regulated by epigenetic modification is an important participant. This study analyzed the effect of CAMP gene methylation on the level of oxidative stress and inflammation of chondrocytes.

Methods
We analyzed the changes of the transcriptome in the articular cartilage tissue of osteoarthritis (OA) patients from the GSE117999 dataset. The GSE48422 dataset was used to analyze the changes in the methylation level of osteoarthritis cells. Cell Counting Kit-8 (CCK-8) and flow cytometry analysis of short hairpin RNA (shRNA) silencing CAMP gene and 5-μM 5-Aza-2’-Deoxycytidine (AZA) treatment on the proliferation and apoptosis of Human chondrocytes osteoarthritis (HC-OA) cells. The Dichloro-dihydro-fluorescein diacetate (DCFH-DA) assay was used to detect the level of reactive oxygen species (ROS), and the expression level of inflammatory factors was analyzed by Western Blot.

Results
The expression of CAMP in cartilage tissue of OA patients was upregulated, and the level of methylation was downregulated. CAMP was highly expressed in osteoarthritis articular cartilage cells. Silencing CAMP inhibited the proliferation of HC-OA cells and promoted their apoptosis. CAMP gene methylation inhibited ROS levels and tumor necrosis factor-α (TNF-α) expression levels in HC-OA cells, and promoted transforming growth factor beta (TGF-β) expression. CAMP gene methylation inhibited the proliferation of HC-OA cells and promoted their apoptosis.

Conclusion
CAMP gene promoter methylation inhibits ROS levels and inflammation and induces chondrocyte apoptosis.

Abstract
Background
Family-Based Treatment (FBT) is considered the first-line intervention for adolescent anorexia nervosa. However, access to this treatment is limited. Treatment programs for other pediatric mental health conditions have successfully overcome barriers to accessing evidence-based intervention by integrating mental health services into primary care. This study evaluated the proof-of-concept of a novel modification of FBT, Family-Based Treatment for Primary Care (FBT-PC) for adolescent restrictive eating disorders designed for delivery by primary care providers in their practices.

Methods
This retrospective clinical cohort study evaluated 15 adolescents with restrictive eating disorders receiving FBT-PC and 15 adolescents receiving standard FBT. We examined improvement in BMI percentile, reduction in weight suppression, and clinical benchmarks of eating disorder recovery including weight restoration to > 95% of expected body weight (EBW) and resolution of DSM-5 criteria for eating disorders.

Results
In both groups, effect sizes for increased BMI percentile exceeded Cohen’s convention for a large effect (FBT-PC: d = .94; standard FBT: d = 1.15) as did effect sizes for reduction in weight suppression (FBT-PC: d = 1.83; standard FBT: d = 1.21). At the end of treatment, 80% of the FBT-PC cohort and 87% in the standard FBT group achieved > 95%EBW and 67% in the FBT-PC group and 60% in the standard FBT group no longer met DSM-5 criteria for an eating disorder. There were no cohort differences in the number of treatment drop-outs or referrals to a more intensive level of eating disorder treatment.

Conclusions
Findings suggest that primary care providers have potential to improve weight and clinical status in adolescents with restrictive eating disorders. Based on these results, more rigorous testing of the FBT-PC model is warranted.

Published: April 2021

AbstractBackgroundNew wildlife telemetry and tracking technologies have become available in the last decade, leading to a large increase in the volume and resolution of animal tracking data. These technical developments have been accompanied by various statistical tools aimed at analysing the data obtained by these methods.MethodsWe used simulated habitat and tracking data to compare some of the different statistical methods frequently used to infer local resource selection and large-scale attraction/avoidance from tracking data. Notably, we compared spatial logistic regression models (SLRMs), spatio-temporal point process models (ST-PPMs), step selection models (SSMs), and integrated step selection models (iSSMs) and their interplay with habitat and animal movement properties in terms of statistical hypothesis testing.ResultsWe demonstrated that only iSSMs and ST-PPMs showed nominal type I error rates in all studied cases, whereas SSMs may slightly and SLRMs may frequently and strongly exceed these levels. iSSMs appeared to have on average a more robust and higher statistical power than ST-PPMs.ConclusionsBased on our results, we recommend the use of iSSMs to infer habitat selection or large-scale attraction/avoidance from animal tracking data. Further advantages over other approaches include short computation times, predictive capacity, and the possibility of deriving mechanistic movement models.

Published: April 2021

Background Physician opioid-prescribing patterns have significant impacts on the current opioid crisis. Patients who use opioids in the postoperative period are at risk of developing chronic postoperative opioid use. This study determined the rate of chronic postoperative opioid use among head and neck cancer patients undergoing primary surgery with free-flap reconstruction. Additionally, this study identified major risk factors associated with the development of chronic postoperative opioid use. Methods A retrospective chart review was performed for all adults (age ≥ 18 years) undergoing primary head and neck surgical resection with free-flap reconstruction between January 2008 and December 2015. Patients were identified from a prospectively collected database, Otobase™. Data from the provincial drug insurance program were used to capture drug dispensing information to determine chronic opioid use at 3- and 12-months postoperatively. Data extracted from Otobase™ included patient demographics, social habits, clinical stage, pathological stage, type of surgery, and adjuvant treatment. Results The total cohort was comprised of 212 patients. Chronic opioid use at 3- and 12- months postoperatively was observed in 136 (64%) and 116 (55%) patients, respectively. Of the 212 patients, 85 patients (40%) were identified as preoperative opioid users and 127 were opioid naïve (60%). Of the 85 patients who were preoperative opioid users, 70 (82%) and 63 (77%) patients continued to use opioids 3- and 12-months postoperatively, respectively. The proportion of opioid-naïve patients who were using opioids at 3- and 12-months postoperatively was 52% (66 patients) and 42% (53 patients), respectively. Identified risk factors included preoperative opioid use, prior tobacco use, advanced pathologic T-stage, and adjuvant treatment. Conclusions Among head and neck cancer patients that have undergone major resection with free-flap reconstruction, the prevalence of chronic postoperative opioid users was considerable. Identified risk factors included preoperative opioid use, prior tobacco use, tumor stage, and adjuvant treatment. Graphical Abstract

Abstract
Introduction
Traumatic brain injury (TBI) is considered as the most robust environmental risk factor for Alzheimer’s disease (AD). Besides direct neuronal injury and neuroinflammation, vascular impairment is also a hallmark event of the pathological cascade after TBI. However, the vascular connection between TBI and subsequent AD pathogenesis remains underexplored.

Methods
In a closed-head mild TBI (mTBI) model in mice with controlled cortical impact, we examined the time courses of microvascular injury, blood–brain barrier (BBB) dysfunction, gliosis and motor function impairment in wild type C57BL/6 mice. We also evaluated the BBB integrity, amyloid pathology as well as cognitive functions after mTBI in the 5xFAD mouse model of AD.

Results
mTBI induced microvascular injury with BBB breakdown, pericyte loss, basement membrane alteration and cerebral blood flow reduction in mice, in which BBB breakdown preceded gliosis. More importantly, mTBI accelerated BBB leakage, amyloid pathology and cognitive impairment in the 5xFAD mice.

Discussion
Our data demonstrated that microvascular injury plays a key role in the pathogenesis of AD after mTBI. Therefore, restoring vascular functions might be beneficial for patients with mTBI, and potentially reduce the risk of developing AD.

Authors: Hirakawa Yusuke , Shigyo Hirona , Katagiri Yuriko , Hashimoto Kazuaki , Katsumoto Mitsuru , Tomoeda Hiroshi , Nakano Masahiko 
Published: April 2021

Abstract
Background
True primary enterolithiasis is an uncommon condition, and nontraumatic perforation of the small intestine (NTPSI) is also an unusual entity. Therefore, NTPSI due to true primary enteroliths is an exceptionally rare complication. Moreover, enterolithiasis and radiation enteritis are also unique combinations. Herein, we present an exceedingly rare case of NTPSI induced by multiple true primary enteroliths associated with radiation enteritis.

Case presentation
A 92-year-old woman with acute abdominal pain was transferred to our hospital because a computed tomography (CT) scan performed by her family doctor revealed free air and fluid collection within her abdomen. Our initial diagnosis was upper gastrointestinal perforation, and we selected nonoperative management (NOM) with adnominal drainage. Although her general condition was stable, jejunal juice was drained continuously. Given that the CT performed 10 days after onset demonstrated perforation of the small intestine and adjacent concretion, we performed an emergency partial resection of the small intestine and jejunostomy. The resected bowel was 1 m in length and had many strictures that contained multiple enteroliths in their proximal lumens. The patient’s postoperative course was uneventful. The enteroliths were composed of deoxycholic acid (DCA). She was diagnosed with peritonitis due to NTPSI derived from multiple true primary enteroliths associated with radiation enteritis, as she had previously undergone hysterectomy and subsequent internal radiation therapy.

Conclusions
Clinicians should consider the rare entity of true primary enteroliths associated with radiation enteritis in NTPSI cases with unknown etiologies.
Laparoscopic transposition for crossing vessels (vascular hitch) in pure extrinsic pelvic-ureteric junction obstruction: a successful case report of a 2-year-old infant with horseshoe kidney
Authors: Ieiri Satoshi , Nagata Kouji 
Published: April 2021

Abstract
Background
Pediatric hydronephrosis induced by pelvic-ureteric junction obstruction (PUJO) is treated by dismembered pyeloplasty (DP) via open and laparoscopic surgery. The etiology of PUJO involves both intrinsic stenosis and extrinsic compression of crossing vessels (CVs). PUJO owing to CVs is also treated by DP, as there is no consensus concerning this vascular condition. We encountered a 2-year-old infant with pure extrinsic PUJO combined with horseshoe kidney who successfully underwent laparoscopic transposition for CVs (vascular hitch).

Case presentation
A 2-year-old boy was prenatally diagnosed with left multicystic dysplastic kidney (MDCK) and right hydronephrosis and received a definitive diagnosis after birth. At 6 months old, renal scintigraphy revealed a non-functioning pattern in the left kidney and an obstructive pattern in the right, showing no response to furosemide loading. The patient also had recurrent urinary tract infection, and his right hydronephrosis gradually worsened. We decided to perform surgery for the right PUJO. Preoperative enhanced computed tomography detected three right renal vessels independently branching from the abdominal aorta. The middle renal vessels were located at the ventral side of the pelvis and coincident with the site of PUJO. These vessels were suspected of being CVs. The patient underwent laparoscopic surgery electively. A 5-mm trocar was inserted at the umbilicus for a 5-mm, 30° rigid scope. Two additional ports were then inserted under laparoscope inspection. The dilated right pelvis and CVs were detected after ascending colon mobilization. To confirm the pathogenesis of PUJO, the CVs were dissected and taped. After taping the CVs, an intraoperative diuretic test was performed using furosemide loading. Peristalsis of the right ureter was recognized, and the extrinsic PUJO owing to the CVs was definitively confirmed. We therefore performed transposition for the CVs (vascular hitch procedure). The CVs were mobilized in the cranial direction and those were wrapped by dilated pelvis. The post-operative course was uneventful. The renal scintigraphy findings improved and showed a favorable response of furosemide loading.

Conclusions
The laparoscopic vascular hitch procedure is minimally invasive and effective for extrinsic PUJO due to CVs. Anastomotic stricture after Anderson and Hynes DP can be prevented by appropriate patient selection.
Multifocal serous retinopathy with pemigatinib therapy for metastatic colon adenocarcinoma
Authors: Alekseev Oleg , Ojuok Effy , Cousins Scott 
Published: April 2021

Abstract
Background
Pemigatinib is an inhibitor of the fibroblast growth factor receptor (FGFR), recently approved for the treatment of cholangiocarcinoma. FGFR retinopathy is a newly recognized entity, with only two other FGFR inhibitors reported to cause serous retinopathy. Herein, we describe the first published report of a multifocal serous retinopathy secondary to pemigatinib.

Case presentation
A 67-year-old male with stage 4A metastatic colon adenocarcinoma undergoing systemic therapy with pemigatinib was found to have developed bilateral multifocal serous retinopathy. Fundus autofluorescence showed corresponding multifocal hypoautofluorescent foci, whereas fluorescein angiography and indocyanine green angiography were unremarkable. Subretinal fluid resolved rapidly after discontinuation of pemigatinib.

Conclusions
Multifocal serous retinopathy appears to be a class effect of FGFR inhibitors. FGFR retinopathy clinically resembles MEK retinopathy—both feature multifocal subretinal fluid, low visual significance, and quick resolution. However, given that FGFR inhibitors have a broader molecular range than MEK inhibitors, further characterization of FGFR retinopathy is necessary to generate management guidelines.
In vitro and in vivo biological control of the green mold using different bacteria in button mushroom cultivation
Authors: Aydoğdu Mehmet , Sülü Serap Melike , Kurbetli İlker , Sülü Görkem 
Published: April 2021

Abstract
Background
Aggressive biotype (Trichoderma aggressivum f. aggressivum) of green mold is one of the main biotic factors limiting button mushroom (Agaricus bisporus) cultivation. Due to issues such as fungicide resistance, cost, and adverse effects, biological control seems to be an applicable management method against the green mold in button mushroom cultivation.

Results
The objective of the study was to assess biological control of green mold in button mushroom cultivation. Five native bacterial isolates from mushroom compost and 3 commercial biological preparations were tested against two isolates of T. aggressivum f. aggressivum. Dual culture tests were used in vitro experiments. In vivo, compost and casing soil experiments were conducted by comparing yield values of treated plots with negative and positive controls. In vitro, the bacterial isolates inhibited mycelial growth of isolates of T. aggressivum f. aggressivum and A. bisporus up to 46.60 and 56.94%, respectively. In vivo, in the compost experiment, compared with positive control plots, bacterial isolate MSG-5 (Bacillus subtilis) caused the highest yield increase (40.56%) in the treatments. In the casing soil experiment, commercial biological preparation Tic-3 (Ampelomyces quisqualis) caused the highest yield increase (36.15%) in the treated plots. Compared with positive and negative controls, all the treatments caused 30.23% increase but 4.86% decrease in yield of A. bisporus in the compost experiment, respectively. However, they caused 20.25% increase but 17.33% decrease in the yield of A. bisporus in the casing soil experiment, respectively.

Conclusions
Results suggested that biological control of the green mold in compost can be more efficient than casing soil in button mushroom cultivation.
Optimizing Implementation in Cancer Control (OPTICC): protocol for an implementation science center
Authors:   OPTICC Consortium, represented by Bryan J. Weiner, Lewis Cara C. , Hannon Peggy A. , Klasnja Predrag , Baldwin Laura-Mae , Hawkes Rene , Blackmer Janell , Johnson Ashley 
Published: April 2021

Abstract
Background
Evidence-based interventions (EBIs) could reduce cervical cancer deaths by 90%, colorectal cancer deaths by 70%, and lung cancer deaths by 95% if widely and effectively implemented in the USA. Yet, EBI implementation, when it occurs, is often suboptimal. This manuscript outlines the protocol for Optimizing Implementation in Cancer Control (OPTICC), a new implementation science center funded as part of the National Cancer Institute Implementation Science Consortium. OPTICC is designed to address three aims. Aim 1 is to develop a research program that supports developing, testing, and refining of innovative, efficient methods for optimizing EBI implementation in cancer control. Aim 2 is to support a diverse implementation laboratory of clinical and community partners to conduct rapid, implementation studies anywhere along the cancer care continuum for a wide range of cancers. Aim 3 is to build implementation science capacity in cancer control by training new investigators, engaging established investigators in cancer-focused implementation science, and contributing to the Implementation Science Consortium in Cancer.

Methods
Three cores serve as OPTICC’s foundation. The Administrative Core plans coordinates and evaluates the Center’s activities and leads its capacity-building efforts. The Implementation Laboratory Core (I-Lab) coordinates a network of diverse clinical and community sites, wherein studies are conducted to optimize EBI implementation, implement cancer control EBIs, and shape the Center’s agenda. The Research Program Core conducts innovative implementation studies, measurement and methods studies, and pilot studies that advance the Center’s theme. A three-stage approach to optimizing EBI implementation is taken—(I) identify and prioritize determinants, (II) match strategies, and (III) optimize strategies—that is informed by a transdisciplinary team of experts leveraging multiphase optimization strategies and criteria, user-centered design, and agile science.

Discussion
OPTICC will develop, test, and refine efficient and economical methods for optimizing EBI implementation by building implementation science capacity in cancer researchers through applications with our I-Lab partners. Once refined, OPTICC will disseminate its methods as toolkits accompanied by massive open online courses, and an interactive website, the latter of which seeks to simultaneously accumulate knowledge across OPTICC studies.
Current status and challenges in drug discovery against the globally important zoonotic cryptosporidiosis
Authors: Zhu Guan , Yin Jigang , Cuny Gregory D. 
Published: April 2021

AbstractThe zoonotic cryptosporidiosis is globally distributed, one of the major diarrheal diseases in humans and animals. Cryptosporidium oocysts are also one of the major environmental concerns, making it a pathogen that fits well into the One Health concept. Despite its importance, fully effective drugs are not yet available. Anti-cryptosporidial drug discovery has historically faced many unusual challenges attributed to unique parasite biology and technical burdens. While significant progresses have been made recently, anti-cryptosporidial drug discovery still faces a major obstacle: identification of systemic drugs that can be absorbed by patients experiencing watery diarrhea and effectively pass through electron-dense (ED) band at the parasite-host cell interface to act on the epicellular parasite. There may be a need to develop an in vitro assay to effectively screen hits/leads for their capability to cross ED band. In the meantime, non-systemic drugs with strong mucoadhesive properties for extended gastrointestinal exposure may represent another direction in developing anti-cryptosporidial therapeutics. For developing both systemic and non-systemic drugs, a non-ruminant animal model exhibiting diarrheal symptoms suitable for routine evaluation of drug absorption and anti-cryptosporidial efficacy may be very helpful.
Strategies for preventing occupational stress in healthcare workers: past evidence, current problems
Authors: De Giorgi Riccardo , Dinkelaar Bianca M. 
Published: April 2021

SUMMARYThe problem of occupational stress in healthcare workers is hardly new, but effective interventions in this area are lacking despite being sorely needed – especially in the ongoing COVID-19 pandemic. The results of a Cochrane review suggest that cognitive–behavioural therapy and mental and physical relaxation reduce stress more than no intervention but not more than alternative interventions, and that changing work schedules may lead to a reduction of stress. Other organisational interventions showed no effect on stress levels. However, the evidence is of low quality owing to risk of bias and lack of precision. This commentary critically appraises the review and attempts to put its findings into the current real-world context.
