Circ_0000396 inhibits rheumatoid arthritis synovial fibroblast growth and inflammatory response via miR-203/HBP1 axis
Authors: Wang Laifang , Zhao Qing , Wang Na , Ding Yanjie , Kong Lingli , Wang Jing
Published: January 2021

Background

Circ_0000396 was found to be down-regulated in the rheumatoid arthritis (RA) patients and had a high diagnostic value. However, the function and mechanisms underlying circ_0000396 in RA progression remain unclear.

Methods

The expression of circ_0000396, microRNA (miR)-203 and HMG-box transcription factor 1 (HBP1) was detected using qRT-PCR and western blot. The proliferative and apoptotic capabilities of rheumatoid arthritis synovial fibroblasts (RASFs) were measured by colony formation, CCK-8, flow cytometry and western blot assays, respectively. The levels of interleukins (IL)-6, IL-1β, IL-8 and tumor necrosis factor-α (TNF-α) were detected using enzyme-linked immunosorbent assay (ELISA). The target correlations between miR-203 and circ_0000396 or HBP1 were validated using pull-down and dual-luciferase reporter assay.

Results

Circ_0000396 was decreased in RA synovial tissues and RASFs, and overexpression of circ_0000396 suppressed cell proliferation, induced cell apoptosis and reduced the release of inflammatory cytokine IL-6, IL-1β, IL-8 and TNF-α in RASFs, while circ_0000396 deletion functioned oppositely. MiR-203 was confirmed to be a target of circ_0000396, and miR-203 reversed the protective effects of circ_0000396 on the dysfunction and inflammation of RASFs. HBP1 was a target of miR-203, and silencing miR-203 inhibited RASFs malignant changes by regulating HBP1. In addition, circ_0000396 could regulate HBP1 by sponging miR-203, and HBP1 decrease attenuated the effects of circ_0000396 on RASF growth and inflammation.

Conclusion

Circ_0000396 inhibited the growth and inflammation in RASFs by regulating miR-203/HBP1 axis, providing a potential therapeutic target for RA.
A scoping review of severe maternal morbidity: describing risk factors and methodological approaches to inform population-based surveillance
Authors: Korst Lisa M. , Gregory Kimberly D. , Nicholas Lisa A. , Saeb Samia , Reynen David J. , Troyan Jennifer L. , Greene Naomi , Fridman Moshe
Published: January 2021

Background

Current interest in using severe maternal morbidity (SMM) as a quality indicator for maternal healthcare will require the development of a standardized method for estimating hospital or regional SMM rates that includes adjustment and/or stratification for risk factors.

Objective

To perform a scoping review to identify methodological considerations and potential covariates for risk adjustment for delivery-associated SMM.

Search methods

Following the guidelines for Preferred Reporting Items for Systematic Reviews and Meta-analyses Extension for Scoping Reviews, systematic searches were conducted with the entire PubMed and EMBASE electronic databases to identify publications using the key term “severe maternal morbidity.”

Selection criteria

Included studies required population-based cohort data and testing or adjustment of risk factors for SMM occurring during the delivery admission. Descriptive studies and those using surveillance-based data collection methods were excluded.

Data collection and analysis

Information was extracted into a pre-defined database. Study design and eligibility, overall quality and results, SMM definitions, and patient-, hospital-, and community-level risk factors and their definitions were assessed.

Main results

Eligibility criteria were met by 81 studies. Methodological approaches were heterogeneous and study results could not be combined quantitatively because of wide variability in data sources, study designs, eligibility criteria, definitions of SMM, and risk-factor selection and definitions. Of the 180 potential risk factors identified, 41 were categorized as pre-existing conditions (e.g., chronic hypertension), 22 as obstetrical conditions (e.g., multiple gestation), 22 as intrapartum conditions (e.g., delivery route), 15 as non-clinical variables (e.g., insurance type), 58 as hospital-level variables (e.g., delivery volume), and 22 as community-level variables (e.g., neighborhood poverty).

Conclusions

The development of a risk adjustment strategy that will allow for SMM comparisons across hospitals or regions will require harmonization regarding: a) the standardization of the SMM definition; b) the data sources and population used; and c) the selection and definition of risk factors of interest.
Intrahepatic cholangiocarcinoma with a tumor thrombus extending from the inferior vena cava to the right atrium: a case report
Authors: Hamano Genya , Takemura Shigekazu , Tanaka Shogo , Shinkawa Hiroji , Aota Takanori , Fujii Hiromichi , Murakami Takashi , Kuwae Yuko , Kubo Shoji
Published: January 2021

Background

Vascular invasion involving a tumor thrombus in the inferior vena cava and/or right atrium is an unfavorable prognostic factor after intrahepatic cholangiocarcinoma resection. We report an intrahepatic cholangiocarcinoma case with a tumor thrombus extending from the left hepatic vein via the inferior vena cava to the right atrium.

Case presentation

A 58-year-old man with epigastralgia was referred to our hospital after an emergent transcatheter arterial embolization was done following the radiological diagnosis of a ruptured hepatic tumor. The serum concentrations of carcinoembryonic antigen, carbohydrate 19-9, duke pancreatic monoclonal antigen type 2, and cytokeratin-19 fragments were elevated; meanwhile those of alfa-fetoprotein and des-γ-carboxy prothrombin were within normal ranges. A contrast-enhanced computed tomography scan showed a heterogeneously enhanced tumor, 13 cm in diameter, in the left lobe of the liver, enlarged lymph nodes along the lesser curvature of the stomach, and a tumor thrombus extending from the left hepatic vein via the inferior vena cava to the right atrium. We performed a left hemihepatectomy and tumor thrombectomy under total hepatic vascular exclusion to reduce the risk of sudden death. After dissection of the liver parenchyma along the left side of the middle hepatic vein, except for the left hepatic vein, the inferior vena cava just below the right atrium could be clamped by pulling down the left lobe of the liver toward the caudal side. The thrombus could be removed by incising the inferior vena cava under total hepatic vascular exclusion. Microscopic examination showed a tubular adenocarcinoma. Immunohistochemical staining was positive for cytokeratin-7, cytokeratin-19, and epithelial membrane antigen, but negative for arginase-1, glypican-3, and hepatocyte. The patient was pathologically diagnosed with an intrahepatic cholangiocarcinoma with a tumor thrombus in the inferior vena cava. Adjuvant chemotherapy with tegafur/gimeracil/oteracil was administered for 1 year. The patient remained in good health without cancer recurrence for over 4 years after the operation.

Conclusion

An aggressive surgical approach may be indicated for intrahepatic cholangiocarcinoma with a tumor thrombus in the inferior vena cava and/or right atrium to avoid the risk of impending death.
Successful closure of a large abdominal wall defect using endoscopic component separation technique in an infant with a giant ventral hernia after staged surgery for omphalocele
Authors: Toma Miki , Yanai Toshihiro , Yoshida Shiho
Published: January 2021

Background

The management of large abdominal wall defects, such as omphalocele or gastroschisis, remains a challenge for pediatric surgeons. Though several techniques have been described to repair those conditions, there is no procedure considered to be the standard worldwide. We report an infant girl with a giant ventral hernia after staged surgery for omphalocele in whom delayed closure of a large abdominal wall defect was performed successfully using “endoscopic component separation technique (ECST)” without serious complications.

Case presentation

A baby girl was admitted to our hospital because of a giant omphalocele, which had been prenatally diagnosed. The omphalocele was supraumbilical and included the entire liver. After staged surgery, a large abdominal wall defect was closed by skin, creating a giant ventral hernia. We performed endoscopic separation component technique (ECST) for the closure of her abdominal wall defect when she was 11 months of age. ECST was initiated with placement of a 5.0-mm port just above the inguinal ligament and under the external oblique muscle. The space between the external and internal oblique muscles was created by the insufflation pressure, and a second 5.0-mm port was placed at 1.0 cm below the inferior edge of the rib into the space. As the further dissection was carried, the aponeurosis of the external oblique muscle was identified as a white line, running vertically from the epigastrium to inguinal ligament. It was transected longitudinally using electrocautery over its full length. The same procedure was performed on the contralateral side and the abdominal wall was successfully closed. Postoperative course was uneventful.

Conclusions

The technique of ECST, described here, is simple and safe for infants, and the cosmetic result is satisfactory.
Pigmented spindle cell variant of a thymic atypical carcinoid in an octogenarian
Authors: Sakamaki Yasushi , Tanaka Ryo , Ishida Daisuke , Tsuji Hiromi , Mike Asako , Yasuoka Hironao
Published: January 2021

Background

A pigmented carcinoid is an extremely rare variant of carcinoid characterized by melanin pigmentation of the tumor, with only five cases described in the literature. In addition, thymic carcinoids are rare in elderly patients and their prognosis after resection of the carcinoid tumor is unclear.

Case presentation

An anterior mediastinal tumor was incidentally found in an 82-year-old man who had been diagnosed with acute thoracic empyema. The tumor was considered most likely to be a noninvasive thymoma or thymic carcinoma for which surgery was indicated after the resolution of the empyema. The tumor was completely resected 4 months after the empyema surgery, and the patient had an uneventful postoperative course. A cut surface of the resected specimen was extensively pigmented and appeared dark-brownish, with abundant melanin pigmentation later confirmed in the spindle-shaped tumor cells. Based on the histologic examination and immunohistochemical study, melanoma was eliminated as a differential diagnosis and the tumor was diagnosed as a pigmented atypical carcinoid of the thymus.

Conclusions

This report provides additional knowledge on thymic pigmented carcinoids and thymic atypical carcinoids in elderly patients.
Prenatally diagnosed congenital pyloric atresia in consecutive three siblings: a case report
Authors: Saka Ryuta , Yamamoto Dan , Kuroda Seika , Ibuka Souji , Kodama Tasuku , Hasegawa Toshimichi
Published: January 2021

Background

Congenital pyloric atresia (CPA) is a rare gastrointestinal anomaly frequently associated with epidermolysis bullosa (EB). Although the complications of familial isolated CPA are minor, delays in diagnosis can increase the chances of morbidity.

Case presentation

Three female infants born to a Japanese mother presented with CPA at birth. There was no consanguinity between the parents, and the spacing between pregnancies was 2 years in each case. All 3 siblings had a prenatal diagnosis of CPA owing to polyhydramnios and a dilated stomach, without dilatation of the rest of the gastrointestinal tract. All patients underwent reconstructive surgeries for establishing bowel continuity (Case 1, pyloromyotomy; Case 2, gastroduodenostomy in a diamond fashion; and Case 3, gastroduodenostomy in a side-to-side fashion) soon after birth. Their postoperative courses were uneventful, and they grew up healthily, without any complications.

Conclusion

Fetal ultrasonography is useful for diagnosing CPA prenatally. Successful prenatal diagnosis can lead to timely intervention after birth.
Implementation of an interprofessional collaboration in practice program: a feasibility study using social network analysis
Authors: Smit Linda C. , Dikken Jeroen , Moolenaar Nienke M. , Schuurmans Marieke J. , de Wit Niek J. , Bleijenberg Nienke
Published: January 2021

Background

Due to multimorbidity and geriatric problems, older people often require both psychosocial and medical care. Collaboration between medical and social professionals is a prerequisite to deliver high-quality care for community-living older people. Effective, safe, and person-centered care relies on skilled interprofessional collaboration and practice. Little is known about interprofessional education to increase interprofessional collaboration in practice (IPCP) in the context of community care for older people. This study examines the feasibility of the implementation of an IPCP program in three community districts and determines its potential to increase interprofessional collaboration between primary healthcare professionals caring for older people.

Method

A feasibility study was conducted to determine the acceptability and feasibility of data collection and analysis regarding interprofessional collaboration in network development. A questionnaire was used to measure the learning experience and the acquisition of knowledge and skills regarding the program. Network development was assessed by distributing a social network survey among professionals attending the program as well as professionals not attending the program at baseline and 5.5 months after. Network development was determined by calculating the number, reciprocity, value, and diversity of contacts between professionals using social network analysis.

Results

The IPCP program was found to be instructive and the knowledge and skills gained were applicable in practice. Social network analysis was feasible to conduct and revealed a spill-over effect regarding network development. Program participants, as well as non-program participants, had larger, more reciprocal, and more diverse interprofessional networks than they did before the program.

Conclusions

This study showed the feasibility of implementing an IPCP program in terms of acceptability, feasibility of data collection, and social network analysis to measure network development, and indicated potential to increase interprofessional collaboration between primary healthcare professionals. Both program participants and non-program participants developed a larger, more collaborative, and diverse interprofessional network.
Precision Family Spirit: a pilot randomized implementation trial of a precision home visiting approach with families in Michigan—trial rationale and study protocol
Authors: Ingalls Allison , Barlow Allison , Kushman Elizabeth , Leonard Amanda , Martin Lisa , Team Precision Family Spirit Study , West Allison L. , Neault Nicole , Haroz Emily E.
Published: January 2021

Background

Home visiting is a well-supported strategy for addressing maternal and child health disparities. However, evidence-based models generally share implementation challenges at scale, including engagement and retention of families. Precision home visiting may address this issue. This paper describes the first known pilot randomized implementation trial of a precision home visiting approach vs. standard implementation. Primary aims are to: 1) explore the acceptability and feasibility of a precision approach to home visiting and 2) examine the difference between Standard Family Spirit and Precision Family Spirit on participants’ program satisfaction, client-home visitor relationship, goal alliance, and the impact of these factors on participant engagement and retention. Secondary aims are to explore potential differences on maternal behavioral and mental health outcomes and child development outcomes to inform sample size estimations for a fully powered study.

Methods

This is a pilot Hybrid Type 3 implementation trial. Four Michigan communities primarily serving the Native American families and already using Family Spirit were randomized by site to receive Standard Family Spirit or Precision Family Spirit. Participants include N = 60 mothers at least 14 years of age (pregnant or with a newborn < 2 months of age) currently enrolled in Family Spirit. Precision Family Spirit participants receive core lessons plus additional lessons based on needs identified at baseline and that emerge during the trial. Control mothers receive the standard sequence of Family Spirit lessons. Data is collected at baseline (< 2 months postpartum), and 2, 6, and 12 months postpartum. All Precision Family Spirit participants are invited to complete qualitative interviews at study midpoint and endpoint. All home visitors are invited to participate in focus groups between study midpoint and endpoint. Exploratory data analysis will assess feasibility, acceptability, client-home visitor relationship, retention, adherence, and potential differences in intervention outcomes.

Discussion

This trial will provide new information about the acceptability and feasibility of precision home visiting and pilot data on program satisfaction, client-home visitor relationship, goal alliance, retention, and targeted maternal-child intervention outcomes. Findings will inform the design of a fully powered randomized implementation trial of precision vs. standard home visiting.

A multi-component, community-engaged intervention to reduce cardiovascular disease risk in perimenopausal Latinas: pilot study protocol
Authors: Cortés Yamnia I. , Berry Diane C. , Perreira Krista M. , Stuebe Alison , Stoner Lee , Giscombé Cheryl Woods , Crandell Jamie , Santíago Lymarí , Harris Latesha K. , Duran Mayra
Published: January 2021

Background

Cardiovascular disease (CVD) risk increases substantially during perimenopause. Latinas have a significantly worse CVD risk factor profile than non-Hispanic White women, potentially due to multiple sociocultural and environmental factors. To date, interdisciplinary interventions have not focused on improving nutrition, physical activity, stress management, and biologic CVD risk in perimenopausal Latinas. The purpose of this study is to examine the feasibility and initial efficacy of a multi-component intervention to reduce CVD risk in perimenopausal Latinas.

Methods

This is a two-group, repeated measures experimental study. Eighty perimenopausal Latinas (age 40–55 years) from two community groups will be randomized: one group will complete the intervention; the other will be a wait-list control. The intervention consists of 12-weekly sessions (education, physical activity, stress management, coping skills training), followed by 3 months of continued support, and 6 months of skill maintenance on their own. The primary outcomes include arterial stiffness, blood pressure, lipids, and blood glucose. Secondary outcomes are health behaviors (nutrition, physical activity, sleep, coping strategies), self-efficacy, and other biological factors related to CVD risk (adiposity, C-reactive protein, hair cortisol, vasomotor symptoms). We will assess changes in outcomes from Time 1 (baseline) to Time 2 (6 months) and Time 3 (12 months) using general linear mixed models to test the hypotheses. We will also evaluate the feasibility of the intervention by assessing enrollment and retention rates, barriers, and facilitators to enrollment, intervention fidelity, the suitability of study procedures, and participant satisfaction with the intervention and study protocol. We hypothesize the intervention group will decrease biologic CVD risk and improve health behaviors and self-efficacy significantly more than the wait-list control.

Discussion

Results from this study will contribute to knowledge on the feasibility of behavioral interventions, including stress management and coping skills training, which could reduce CVD burden among perimenopausal Latinas. Because Hispanic/Latinos are the largest ethnic minority in the United States (US), progress regarding CVD risk among perimenopausal Latinas may lead to significant improvement in the overall CVD burden in the US.

“A little (PPI) MAGIC can take you a long way” : involving children and young people in research from inception of a novel medical device to multi-centre clinical trial Roald Dahl, James and the Giant Peach (1961)
Authors:   the Young Persons Advisory Group, Abrehart Nichola , Frost Kate , Harris Roy , Wragg Andrew , Stewart Derek , Sharif Hayfa , Matthews Rachel , Marciani Luca
Published: January 2021

Background

There is often a great urgency to be inclusive when conducting research and to focus efforts with groups and communities that can be referred to as marginalised. This is especially the case in research concerning medical devices aimed at children and young people (CYP). Although involvement methodology has developed over the last two decades, it can be challenging to involve and engage CYP with confidence and clarity of purpose.

Main body

Our aim was to provide a reflective narrative account of the involvement of CYP, over a period of 5 years, in a research project from conception of a new paediatric medical device through to practical application. We explored a model of patient and public involvement (PPI) through the Nottingham Young Persons Advisory Group (YPAG), part of the National Institute for Health Research (NIHR) GenerationR Alliance, in a NIHR funded research project.

The YPAG designed and created a model of the human gut, co-designed the Transicap™ mini-capsules and their packaging, co-produced patient information sheets, came up with the idea to disseminate through a project website and co-wrote and created animation videos. The YPAG involvement continued through the writing and award of the follow-on research grant (MAGIC2). During this process the YPAG modified the clinical study protocol insisting that all participants in the control arm were given the imaging test results as well, save for a delayed reading compared to the intervention arm.

Conclusion

Involvement of the YPAG over the last 5 years, led to the development of a mutually beneficial partnership, enabling genuine knowledge exchange between researchers and CYP. This influenced the design, plans and actions of the MAGIC study and well into the subsequent MAGIC2 follow-on project. Moreover, these involvement models applied within a feasibility study setting, have enhanced the realism and pragmatism of the study, contributing to the project’s overall success.
Broadening diversity through creative involvement to identify research priorities

Published: January 2021

Background

Patient and public involvement (PPI) can help with steering and shaping research prioritisation and execution. However, some groups of people may not be encouraged to take part and their voices may be seldom listened to in the production of research. This is important to consider because they may have poorer healthcare experiences. We tried using art as a vehicle for including individuals not necessarily invited to be part of research priority setting.

Methods

We contacted existing groups and organisations to reach people not routinely supported to be part of PPI. We targeted individuals: a) with dementia, b) with a mental and physical health condition, c) of South Asian heritage. We ran a workshop with each group at which individuals shared their experiences of healthcare. A young amateur artist also attended, who produced a piece of artwork afterwards that reflected the research priorities raised. We held a Twitter chat to discuss these pieces of art and the processes involved in their generation.

Results

From each workshop, we produced a list of research priorities. These included: a) improving coordination of care for people with dementia, b) information needs and anxiety/guilt around accessing care for people with physical and mental health conditions, c) supporting discussion of women’s health issues in South Asian communities. These priorities were reflected in three pieces of art, which can be viewed online. Feedback from those at workshops suggested that the artwork helped them to feel that their voice had been heard and triggered their interest in how research is developed. Those involved in the Twitter chat commented that art was one means through which researchers could connect with a range of groups in a PPI context when preparing and producing a study.

Conclusions

We found the medium of art to be an effective way of including a range of people in research prioritisation setting. This approach could be useful for future PPI, building on what we have learnt from the project described in this paper.
Congenital heart disease in Down syndrome – A review of temporal changes
Authors: Santoro Stephanie L. , Steffensen Ellen Hollands
Published: January 2021

Background

Congenital heart disease (CHD) is a well-known co-occurring condition in Down syndrome (DS). We aimed to review the literature to evaluate the current evidence to address key questions.

Methods

A series of key questions were formulated a priori to inform the search strategy and review process. These addressed the topics of prevalence, type of CHD, severity, and screening. Using the National Library of Medicine database, PubMed, detailed literature searches were performed. The quality of available evidence was then evaluated, the existing literature was summarized, and knowledge gaps were identified.

Results

Fifty-six relevant original articles were identified which addressed at least one key question. Study details, including: research design, internal validity, external validity, and relevant results are presented. The total prevalence of CHD reported in DS ranged from 20 to 57.9%. In later decades, the prevalence remained constant at 40—55%. The types and classification of CHD varied considerably between studies. Some studies indicate a trend towards a milder phenotype, but this was not consistent. Over time, some studies observed an improved prognosis for CHD in DS. Studies investigating screening for CHD by physical examination, chest X-ray, and electrocardiogram report sensitivities of 71–95%.

Conclusion

To further improve knowledge on CHD in DS, we suggest that future studies cover a wide range of nations and regions, with a longitudinal design, and account for potential confounding factors.
Successful anesthetic management of separation surgery for pygopagus conjoined twins: a case report
Authors: Sato Yukari , Iura Akira , Kawamoto Yu , Yamamoto Shunsuke , Iritakenishi Takeshi , Fujino Yuji
Published: January 2021

Background

Conjoined twins are an extremely rare congenital occurrence, and anesthetic management for surgical separation presents unique challenges for anesthesiologists.

Case presentation

Five-month-old male pygopagus conjoined twins underwent separation surgery. We performed anesthesia induction in the supine position and surgery in the prone position. This presented a challenge because the transition from supine to prone position reversed the positional relationship between the two babies, resulting in crossing of the respiratory circuits and monitors. To solve the problem, we used anesthesia machines and monitors on the opposite side of each baby during anesthesia induction. The positional relationship between the twins and anesthesia machines and monitors normalized after the change to the prone position. Following the separation surgery, the twins were discharged without any complications.

Conclusions

Our method of using opposite side anesthetic machines and monitors for anesthesia induction was useful for the safe anesthetic management of pygopagus conjoined twins.

Authors: Fujimoto Yuri , Hamachi Ryosuke , Motoyama Yoshimasa , Kanna Etsuko , Murakami Masako , Matsukado Takako , Saito Genkichi , Yamaura Ken
Published: January 2021

Background

Cases of systemic thromboembolism due to thrombus formation in the pulmonary vein stump after lobectomy have been reported recently. Cerebral infarction after left upper lobectomy is a common symptom in these cases. We encountered a rare case of acute limb ischemia caused by a thrombus formed in the left inferior pulmonary vein stump after left lower lobectomy.

Case presentation

A 62-year-old man underwent video-assisted left lower lobectomy under general anesthesia with epidural anesthesia. On postoperative day 2, he suddenly developed pain in the left calf. Contrast-enhanced computed tomography showed left popliteal artery occlusion and thrombus formation in the left inferior pulmonary vein stump. Anticoagulant therapy was started immediately, and emergent endovascular thrombectomy was performed. The patient recovered without complications.

Conclusions

Left lower lobectomy can cause thrombus formation in the pulmonary vein stump, leading to systemic thromboembolism. Early detection and treatment are the keys to minimize complications.

Published: January 2021

Regional contraceptive use differentials are pronounced in Ghana, with the lowest levels occurring in the Northern Region. Community-based health services, intended to promote maternal and child health and family planning use, may have failed to address this problem. This paper presents an analysis of qualitative data on community perspectives on family planning “readiness,” “willingness,” and “ability” compiled in the course of 20 focus group discussions with residents (mothers and fathers of children under five, young boys and girls, and community elders) of two communities each in two Northern Region districts that were either equipped with or lacking direct access to community health services. The study districts are localities where contraceptive use is uncommon and fertility is exceptionally high. Results suggest that direct access to community services has had no impact on contraceptive attitudes or practice. Widespread method knowledge is often offset by side-effect misperceptions. Social constraints are prominent owing to opposition from men. Findings attest to the need to improve the provision of contraceptive information and expand method choice options. Because societal acceptance and access in this patriarchal setting is critical to use, frontline worker deployment should prioritize strategies for outreach to men and community groups with prominent attention to social mobilization themes and strategies that support family planning.
Comparing cost and print time estimates for six commercially-available 3D printers obtained through slicing software for clinically relevant anatomical models
Authors: Chen Joshua V. , Dang Alan B. C. , Dang Alexis
Published: January 2021

Background

3D printed patient-specific anatomical models have been applied clinically to orthopaedic care for surgical planning and patient education. The estimated cost and print time per model for 3D printers have not yet been compared with clinically representative models across multiple printing technologies. This study investigates six commercially-available 3D printers: Prusa i3 MK3S, Formlabs Form 2, Formlabs Form 3, LulzBot TAZ 6, Stratasys F370, and Stratasys J750 Digital Anatomy.

Methods

Seven representative orthopaedic standard tessellation models derived from CT scans were imported into the respective slicing software for each 3D printer. For each printer and corresponding print setting, the slicing software provides a print time and material use estimate. Material quantity was used to calculate estimated model cost. Print settings investigated were infill percentage, layer height, and model orientation on the print bed. The slicing software investigated are Cura LulzBot Edition 3.6.20, GrabCAD Print 1.43, PreForm 3.4.6, and PrusaSlicer 2.2.0.

Results

The effect of changing infill between 15% and 20% on estimated print time and material use was negligible. Orientation of the model has considerable impact on time and cost with worst-case differences being as much as 39.30% added print time and 34.56% added costs. Averaged across all investigated settings, horizontal model orientation on the print bed minimizes estimated print time for all 3D printers, while vertical model orientation minimizes cost with the exception of Stratasys J750 Digital Anatomy, in which horizontal orientation also minimized cost. Decreasing layer height for all investigated printers increased estimated print time and decreased estimated cost with the exception of Stratasys F370, in which cost increased. The difference in material cost was two orders of magnitude between the least and most-expensive printers. The difference in build rate (cm3/min) was one order of magnitude between the fastest and slowest printers.

Conclusions

All investigated 3D printers in this study have the potential for clinical utility. Print time and print cost are dependent on orientation of anatomy and the printers and settings selected. Cost-effective clinical 3D printing of anatomic models should consider an appropriate printer for the complexity of the anatomy and the experience of the printer technicians.
Influence of fishmeal-replaced diet on nutrient digestibility, digestive enzyme activity, and whole-body fatty acid profile of Indian major carp, Cirrhinus mrigala
Authors: Pradhan Chiranjiv , Giri Shiba Shankar , Mohanty Satyandra Nath , Nayak Khiroda Chandra
Published: January 2021

Background

The aquaculture sector is the biggest consumer of fishmeal and the demand of this ingredient is higher than the production. The replacement of fishmeal from aquafeed is a current research thrust. The replacement of fishmeal has been possible with plant ingredients in many fish species, however, possesses some limitations in terms of low digestibility and inadequate nutrient profile.

Results

Complete replacement of fishmeal in the diets of Cirrihinus mrigala was studied using specially designed nutrient digestibility system. Two feeds were prepared, one with fishmeal as one of the ingredients (control feed) and another with complete plant ingredients (test feed). Initially, forty C. mrigala fingerlings with average weight of 10.88 ± 0.17 g were stocked in six tanks. Fish were fed up to satiation twice daily (10:00 and 16:30 h) for a period of 45 days. After 1 week of acclimatization, fecal samples were collected for 45 days. At the end of the experiment, no significant differences (P > 0.05) were observed for somatic and serum parameters in two treatments. The digestibility coefficient of dry matter, protein, lipid and energy, and three digestive enzymes; amylase, proteases, and lipase did not differ significantly (P > 0.05) between the treatments. The whole body proximate compositions were similar between the treatments. The test diet (containing linseed oil) fed group exhibited higher proportions of whole body linolenic acid (ALA, 18:3n-3). However, eicosapentaenoic acid (EPA, 20:5n-3) and docosahexaenoic acid (DHA, 22:6n-3) did not vary in both studied treatments.

Conclusion

The information obtained from this study revealed that fishmeal can be completely replaced from the diet of C. mrigala without affecting their growth and nutrient digestibility and fatty acid composition.
Susceptibility of ten rice brands to weevil, Sitophilus oryzae L. (Coleoptera: Curculionidae), and their influence on the insect and infestation rate
Authors: Okpile Chilee , Zakka Usman , Nwosu Luke Chinaru
Published: January 2021

Background

Susceptibility studies keep farmers, managers and household users informed and enhance breeding program’s testing against infestation and damage by storage insect pests. Therefore, laboratory tests were carried out to examine the susceptibility of ten rice brands to rice weevil, Sitophilus oryzae L. (Coleoptera: Curculionidae), infestation under temperature and relative humidity of 25 ± 2 °C and 75 ± 5%, respectively. The specific objectives of the study were to identify some commercially available rice brands with resistance to S. oryzae, by determining whether brand difference influences insect body weight at emergence and whether infestation is related to brand palatability and appearance. The ten brands used for the study were royale stallion, Mama royale, parboiled rice, Mama gold, white rice, Super eagle, Indian rice, champion rice, Abakiliki rice and Mama Africa, and standard methods were used to achieve the objectives. The indices measured were F1 progeny emergence, grain weight loss and frass accumulation.

Results

The results showed that Abakiliki rice was poor in both palatability and appearance, whereas Super eagle was the most palatable and white rice was visually excellent. The results further showed that no brand was resistant to infestation and damage by S. oryzae. Males that were bred on the different rice brands did not differ in weight at emergence, but the weight of females at emergence was influenced by brand difference, and this suggests that female insects are more sensitive to brand difference at weight gain.

Conclusion

Palatability and appearance were important in the susceptibility of rice brands to S. oryzae. The proliferation of diverse genotypes of rice (branded) with enhanced resistance to S. oryzae should be strongly encouraged to reduce susceptibility and increase rice security.

Background

Hepatitis C virus (HCV) is a global medical condition that causes several life-threatening chronic diseases in the liver. The conventional interferon-free treatment regimens are currently in use by a blend of direct-acting antiviral agents (DAAs) aiming at the viral NS3 protease. However, major concerns may be the issue of DAA-resistant HCV strains and the limited availability to the DAAs due to their high price. Due to this crisis, the developments of a new molecule with high potency as an NS3/4A protease inhibitor of the hepatitis-C virus remain a high priority for medical research. This study aimed to use in-silico methods to identify high potent molecule as an NS3/4A protease inhibitor and investigating the binding energy of the identified molecule in comparison with approved direct-acting antiviral agents (Telaprevir, Simeprevir, and Voxilaprevir) through molecular docking.

Results

The model obtained by in-silico method have the following statistical records, coefficient of determination (r2) of 0.7704, cross-validation (q2LOO = 0.6914); external test set (r2(pred) = 0.7049) andY-randomization assessment (cR2p = 0.7025). The results from the model were used to identify 12 new potential human HCV NS3/4A protease inhibitors, and it was observed that the identified molecule is well-fixed when docked with the receptor and was found to have the lowest binding energy of − 10.7, compared to approved direct-acting antiviral agents (Telaprevir, Simeprevir, and Voxilaprevir) with − 9.5, − 10.0, − 10.5 binding energy, respectively.

Conclusion

The binding affinity (− 10.7) of the newly identified molecule docked with 3D structures of HCV NS3/4a protease/helicase (PDB ID: 4A92) was found to be better than that of Telaprevir, Simeprevir, and Voxilaprevir (approved direct-acting antiviral agents) which are − 9.5, − 10.0, and − 10.5, respectively. Hence, a novel molecule was identified showing high potency as HCV NS3/4a protease inhibitors.

Background

The global warming has become a worldwide problem affecting adversely the human being and the productivity of the livestock. This study aimed to investigate the effect of seasonal heat stress on the incidence of retained fetal membranes, oxidant-antioxidant biomarkers, haptoglobin, mineral status, milk production, inseminations/conception, estradiol, and days open of Holstein Friesian cows raised under Egyptian environmental conditions. Blood samples were collected one week before parturition and one day after parturition from two dairy farms. Total proteins, albumin, nitric oxide (NO), glutathione reduced (GSH), haptoglobin, estradiol, calcium, phosphorus, iron, copper and zinc were measured in the blood serum for cows delivered during the hot months (May to September) and the cold months (December to April).

Results

Cows delivered during the hot months had the highest prevalence of retained placenta and were older (P = 0.0001) of mean parity (4.93 ± 2.24), required more services/conception (P = 0.0001; 3.14 ± 1.20), produced higher (P = 0.0001) milk yield/Ton (8.43 ± 1.29) compared to those retained during the cold months (8.00 ± 1.03). All cows retained their placentae had low estradiol ((P = 0.0001) compared to those dropped their placenta within the same season. All cows retained their fetal membranes had high NO (P = 0.0002) but low GSH (P = 0.008), and globulin (P = 0.041). During the hot months, cows with retained placenta obtained low calcium, corrected calcium and calcium/phosphorus ratio. The type of placental drop and its interaction with season influenced (P < 0.01) services /conception, milk yield, NO, estradiol and copper.

Conclusions

The retention of fetal membranes decreased the productive and reproductive parameters and its effects deteriorated reproduction and immunological status during the hot months.
Termiticidal activity of oil from Jatropha curcas L. and Azadirachta indica A. Juss against Coptotermes sjostedti Holmgren (Isoptera: Rhinotermitidae)

Background

Coptotermes sjostedti Holmgren (Isoptera:Rhinotermitidae) is one of the major termite species found infesting woods and other plant materials in Africa. Bioassays were carried out at the Arboretum of the Department of Forestry and Wildlife Resources Management, University of Calabar, Nigeria to investigate the effect of oils from the kernel of Jatropha curcas L. and Azadirachta indica oils A. Juss against the African subterranean termite (Coptotermes sjostedti Holmgren). Treatments comprised of the plant oils and Solignum (a synthetic termiticide, serving as positive control) applied at the rate of 5, 10 and 15 mL per 100 cm3 of the wood from seven plant species. Untreated woods also served as control. Seven wood species were placed in a test arena and artificially infested with 50 termites per unit. The setup was a randomized complete block design with four replicates. Data on termite mortality and wood weight loss were recorded.

Results

The use of 10 and 15 mL of J. curcas oil caused more than 90% mortality of C. sjostedti, after 96 h, kept wood consumption by the insect below 6.0% after 3 months, and these outcomes were similar to that of Solignum at the same concentrations. About 35.0–65.2% reduction in weight was observed among untreated woods from the tested woods, indicating their susceptibility to C. sjostedti attacks. Correlation analysis shows a significant (r > − 0.900; P < 0.0001) negative association between termite mortality and the  rate of wood consumption.

Conclusion

The use of J. curcas oil at 10 mL per 100 cm3 of wood could be a potent alternative to Solignum for the control of C. sjostedti.

Background

Relationships between microbial composition and steatosis are being extensively studied in mammals, and causal relations have been evidenced. In migratory birds the liver can transiently store lipids during pre-migratory and migratory phases, but little is known about the implications of the digestive microbiota in those mechanisms. The Landaise greylag goose (Anser anser) is a good model to study steatosis in migratory birds as it is domesticated, but is still, from a genetic point of view, close to its wild migratory ancestor. It also has a great ingestion capacity and a good predisposition for hepatic steatosis, whether spontaneous or induced by conventional overfeeding. The conventional (overfeeding) and alternative (spontaneous steatosis induction) systems differ considerably in duration and feed intake level and previous studies have shown that aptitudes to spontaneous steatosis are very variable. The present study thus aimed to address two issues: (i) evaluate whether microbial composition differs with steatosis-inducing mode; (ii) elucidate whether a digestive microbial signature could be associated with variable aptitudes to spontaneous liver steatosis.

Results

Performances, biochemical composition of the livers and microbiota differed considerably in response to steatosis stimulation. We namely identified the genus Romboutsia to be overrepresented in birds developing a spontaneous steatosis in comparison to those submitted to conventional overfeeding while the genera Ralstonia, Variovorax and Sphingomonas were underrepresented only in birds that did not develop a spontaneous steatosis compared to conventionally overfed ones, birds developing a spontaneous steatosis having intermediate values. Secondly, no overall differences in microbial composition were evidenced in association with variable aptitudes to spontaneous steatosis, although one OTU, belonging to the Lactobacillus genus, was overrepresented in birds having developed a spontaneous steatosis compared to those that had not.

Conclusions

Our study is the first to evaluate the intestinal microbial composition in association with steatosis, whether spontaneous or induced by overfeeding, in geese. Steatosis induction modes were associated with distinct digestive microbial compositions. However, unlike what can be observed in mammals, no clear microbial signature associated with spontaneous steatosis level was identified.
