B vitamins, polycystic ovary syndrome, and fertility
Authors: Thornburgh Sarah , Gaskins Audrey J. 
Published: September 2022

Purpose of review
This review provides a general overview of the literature on B vitamins and fertility, as well as summarizes the evidence concerning B vitamin supplementation and fertility among polycystic ovary syndrome (PCOS) women.

Recent findings
Studies among women conceiving with and without medical assistance provide strong evidence for a beneficial effect of B vitamins, particularly folate and vitamin B12, on fecundability and fertility. Moreover, recent work suggests that effects may be even more pronounced among women with menstrual cycle dysfunction (a common symptom of PCOS). Among PCOS women, intervention studies have demonstrated that folic acid supplementation may reduce homocysteine levels, potentially improve women's metabolic profiles, and possibly ameliorate some hallmark features of PCOS. Although none of these intervention studies have included fertility endpoints, it is possible that by reducing homocysteine levels (or other clinical/biochemical features) in PCOS women, there may be a downstream improvement in fertility outcomes.

Summary
There is growing evidence folate (and possibly vitamin B12) supplementation may be beneficial to fertility in women. Although most studies have not exclusively focused on women with PCOS, there is biological plausibility and some evidence that B vitamin supplementation may be even more important for improving reproductive health outcomes in PCOS women.

Published: September 2022

Background
Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) is a developing therapeutic approach for premalignant pancreatic-cystic neoplasms (PCNs) and small pancreatic neuroendocrine tumors (PNETs). The safety and efficacy of pancreatic EUS-RFA were previously reported in small series. Herein we report our initial experience with RFA of PCNs and small PNETs.

Methods
This is a prospective single-center study including 12 patients with a median follow-up of 7 months, with either PCN or PNET <2 cm. Eligible PCNs were either intraductal papillary mucinous neoplasms (IPMN) with worrisome features or mucinous cystic neoplasms (MCN) that were not eligible or refused surgery. Ablation was performed using a 19-gauge dedicated needle.

Results
Twelve patients were treated, five had PCNs (four IPMNs, one MCN; median size of 36 mm, range 12–60) and seven had PNETs (median size 8.9 mm, range 6–18). Among patients with PCNs, the complete radiologic response was achieved in 3/5 (60%), partial response in 1/5 (20%) and failure in 1/5 (20%). Among six patients with nonfunctioning PNETs, the complete radiologic response was achieved in 4/6 (66.7%), partial radiologic response in 0/6 (0%) and failure in 2/6 (33.3%). Following a median follow-up of 7 months. One patient with insulinoma showed complete resolution of hypoglycemia-related symptoms. Three postprocedural adverse events occurred, including one case (1/12, 8.3%) of mild acute pancreatitis and two cases (2/12, 16.7%) of abdominal pain.

Conclusion
EUS-guided RFA for premalignant PCNs and PNETs is feasible and well-tolerated. Efficacy would be further evaluated with continued follow-up of patients.

Published: September 2022

Background
There remains limited data supporting the efficacy of dietary therapy in adults with Crohn’s disease (CD). This was a pilot study of the McMaster Elimination diet for CD (MED-CD), which excludes several potentially detrimental ingredients commonly found in the Western diet.

Methods
Prospective study in adults with mild-moderately active CD [Harvey–Bradshaw Index (HBI) scores 5–16] and endoscopic disease activity of >7 (or ≥4 for isolated ileal disease) as measured by the Simple Endoscopic Score for Crohn’s disease (SES-CD). Patients were treated for 2 weeks using oral enteral nutrition (EN). Those with symptomatic improvement (HBI score reduction ≥2) were transitioned to the MED-CD for 12 weeks. Outcomes of interest included satisfactory adherence (≥20 on the modified medical adherence report scale-5 questionnaire), clinical remission (CR) (HBI ≤4), clinical response (HBI reduction ≥3), endoscopic response (SES-CD reduction ≥50%), and endoscopic remission (ER) (SES-CD <3).

Results
A total of 17 patients were treated with 2 weeks of EN. Of these, 13 were deemed responders and treated with 12 weeks of MED-CD. Satisfactory adherence was reported among 11/13 (84.6%) at week 6 and 8/12 (67%) at week 14. Of the 13 patients who responded to EN by week 2, 5 (38.5%) had attained CR at week 2 and maintained CR until week 14 using MED-CD. Endoscopic response was observed in 6 (46.2%) participants and ER was seen in 2 (15.4%).

Conclusions
Two weeks of oral EN followed by 12 weeks of the MED-CD was acceptable by most adult patients who enroled in this study.
Subjective norms as a moderator in the consumption behaviour of branded functional beverages post-COVID-19 pandemic: a pragmatic view
Authors: Natarajan Thamaraiselvan , Geetha Raveendran Nair Jayadevan , Jayapal Jegan 
Published: September 2022

PurposeThis study aims to experimentally investigate branded functional beverage (BFB) consumption behaviour post-COVID-19 through the lens of a conceptual framework built on three renowned behaviour modification models and to critically evaluate how well subjective norms serve as a moderator in the consumption behaviour relating to such beverage products.Design/methodology/approachA conceptual model was developed based on the tenets of the theory of planned behaviour (TPB), health belief model (HBM) and value-attitude-behaviour (VAB) model. The study was performed on a convenience sample of 537 respondents aged 18 and up from diverse regions in India using the PLS-SEM method. A total of 444 useable questionnaires were utilized for the final data analysis.FindingsGiven the post-pandemic setting, the perceived benefits of BFBs significantly influenced its purchase intention and consumption behaviour. It could grossly impact the media's role (information about COVID-19) and the consumers' interest in healthy food. The study revealed that the information about COVID-19 (role of media) strongly increased interest in healthy food, whereas interest in healthy food positively influenced purchase intention of functional beverages. With interest in healthy food as a “mediator”, the role of media (information about COVID-19) positively influenced purchase intention. It is worth noting the moderating role of subjective norms in the relationship between the role of media (information about COVID-19) and interest in healthy food and that between interest in healthy food and BFB purchase intention.Practical implicationsFood marketers shall skillfully use “opinion” leaders and subject experts in marketing communication campaigns to popularize the link between good food and immunity through COVID-19 and healthy diet-related messages sent via a suitable media platform. This would grab food consumers' interest in BFBs and persuade them to incorporate such items in their daily food milieu. Consumers need to be assured that consuming “functional” products would deliver health benefits and upkeep their body immunity in the post-COVID-19 times.Originality/valueThere has been minimal research on the link between perceived benefits, the role of media, interest in healthy food and consumption behaviour on functional beverages in the post-COVID-19 setting. Moreover, subjective norms have never been probed as a moderator in the consumer behaviour studies on BFBs. This pioneering study applied the tenets of the TPB, HBM and VAB model in the context of post-pandemic functional beverage consumption. The altered study settings caused by the COVID-19 pandemic and the context of a developing economy like India have amplified the research value of this study.

Published: September 2022

Purpose
The purpose of this study is to develop a reliable finite element algorithm based on the transmission line method (TLM) to solve the nonlinear problem in electromagnetic field calculation.

Design/methodology/approach
In this paper, the TLM has been researched and applied to solve nonlinear iteration in FEM. LU decomposition method and the Jacobi preconditioned conjugate gradient method have been investigated to solve the equations in transmission line finite element method (FEM-TLM). The algorithms have been developed in C++ language. The algorithm is applied to analyze the magnetic field of a long straight current-carrying wire and a single-phase transformer.

Findings
FEM-TLM is more effective than traditional FEM in nonlinear iteration. The results of FEM-TLM have been compared and analyzed under different calculation scales. It is found that the LU decomposition method is more suitable for FEM-TLM because there is no need to repeatedly assemble the global coefficient matrix in the iterative solution process and it is not affected by the disturbance of the right-hand vector.

Originality/value
An effective algorithm is provided for solving nonlinear problems in the electromagnetic field, which can save a lot of computing costs. The efficiency of LU decomposition and CG method in FEM-TLM nonlinear iteration is investigated, which also makes a preliminary exploration for the research of FEM-TLM parallel algorithms.
Believe to achieve? Understanding how social class background impacts the effects of achievement striving on propensity to negotiate

Published: September 2022

PurposeNegotiation is important for career success. Therefore, this study draws from social expectancy and self-regulation theories to develop a model proposing that social class background (SCB) influences the ease with which achievement striving translates into propensity to negotiate. Specifically, the authors examine how SCB moderates the relationship between achievement striving and negotiation propensity via a key mediator—status-based identity uncertainty—reflective of one's (un)certainty about their societal standing.Design/methodology/approachThe authors collected data across three surveys over a four-week period from 460 participants. The authors assessed negotiation propensity by asking participants to rank-order behavioral reactions, representative of different degrees of negotiation engagement, in response to three scenarios.FindingsThe positive effects of achievement striving on negotiation propensity are attenuated for individuals with lower SCBs, in part, because achievement-oriented individuals with lower SCBs experience a heightened sense of status-based identity uncertainty. Although achievement striving is an asset for initiating negotiations, it appears to disproportionately benefit those with higher SCBs.Originality/valueIndividuals higher in achievement striving and with lower SCBs may approach the negotiation process differently than those with higher SCBs. This dynamic serves as another mechanism through which cumulative (dis)advantage processes in career success may occur over time.
Reservoir characterization and density–velocity analysis using rock physics and integrated multi‐types post‐stack inversion to identify hydrocarbon possibility and litho‐prediction of Mishrif formation in the Kumaite and Dhafriyah oil fields, Southern Iraq
Authors: Albakr Majid A. , Abd Najah , Hasan Salar , Al‐Sharaa Ghazi H. 
Published: September 2022

AbstractLitho‐prediction is a non‐unique process that requires more than integrated techniques to reinforce the final results and harmonize hydrocarbon probability. Consequently, integrated procedures have been started with log data of the Mishrif formation in different site locations and involve petrophysics and rock physics analyses altogether to evaluate the general situation of the formation. In the second stage, we performed seismic inversion for 3D seismic data in the Kumaite and Dhafriyah oil fields. A brand‐new technique called pseudo–post‐stack simultaneous inversion has been used to calculate all the elastic engineering properties of the seismic cube. This method is performed by utilizing a real genetic inversion model that would be used to calibrate a low‐frequency model of simultaneous inversion to enhance the resolution and event isolation of the final inverted cube to identify reservoir characterization. The final output then is used to perform quantitative analysis and determine the productive layers within the area of interest. Density–velocity analysis also plays an extraordinary role in establishing the main relationship between different elastic parameters. Finally, by using the local equation and global density–velocity equations, different velocities of carbonate succession have been calculated.
Back to the future: when children and adolescents return to office sessions following episodes of teletherapy
Authors: Tyminski Robert 
Published: September 2022

AbstractAnalysts and psychotherapists are beginning to have more thorough and probing discussions about how the COVID‐19 pandemic has affected their work. Shifting to online teletherapy has been necessary due to the public health measures put in place to curtail the spread of the virus. Much of the existing literature addresses how using online platforms for teletherapy works for adults. This paper instead looks at its effects on working with children and adolescents. A contrast between Winnicott’s notion of holding and Bion’s concept of container‐contained is reviewed through a summary of a paper by Ogden. This author finds that holding might be more applicable to online work during a pandemic when the collective relationship to time and its usual parameters is severely upended. Containing could be more arduous and challenging online due to the lack of embodied presence to communicate and detect tiny nonverbal cues. A short questionnaire affirms that child analysts and psychotherapists have struggled with dimensions of online work that are particular to the developmental levels of their patients. Further, teletherapy may often not be a good fit for someone with learning differences.
Conceptualising employee voice in the majority world: Using multiple intellectual traditions inspired by the work of Mick Marchington

Published: September 2022

AbstractConceptualisation of voice in the majority world (developing and emerging economies) should avoid simply using the lens of the minority world (advanced economies). Yet, both can benefit from taking a multidisciplinary approach. Marchington was one of the early pioneers of multidisciplinary work on voice in advanced economies. While being fundamentally an industrial relations (IR) scholar who was alert to the influence of power and context, he took a pluralist approach in applying IR ideas to Human Resource Management, exploring empirically why and how workers use voice. This paper is inspired by Marchington's multidisciplinary approach but considers voice within different institutional contexts. Our key research question is, ‘How can majority world conceptions of employee voice enrich our understanding of what voice is for, its outcomes and whom it serves?’ Through interrogating how different intellectual traditions have underpinned work in the majority world (exemplified by South Africa and China) we highlight the need for further theoretical development of the concept of lateral voice and argue that voice should be more closely linked to forms of resistance. Our concluding section uses this analysis to start the re‐imagining of voice in minority and majority world contexts.

SummaryBackgroundThere are limited data on the diagnostic accuracy of gut microbial signatures for predicting hepatic decompensation in patients with cirrhosis.AimsTo determine whether a stool metagenome‐derived signature accurately detects hepatic decompensation and mortality risk in cirrhosis secondary to non‐alcoholic fatty liver disease (NAFLD)MethodsShotgun metagenomic sequencing was performed on faecal samples collected at study entry from a prospective cohort of adults with NAFLD‐related cirrhosis. A Random Forest machine learning algorithm was utilised to identify a metagenomic signature of decompensated cirrhosis (defined by ascites, hepatic encephalopathy or variceal haemorrhage) and subsequently validated in an external cohort. A Cox proportional hazards regression model was used to examine predictors of all‐cause mortality.ResultsIn all, 25 adults with NAFLD‐related cirrhosis (training cohort) were included. Among the 16 participants with decompensated cirrhosis, 33% had ascites, 56% had hepatic encephalopathy and 22% had experienced a variceal haemorrhage (not mutually exclusive). We identified a stool metagenomic signature comprising 13 discriminatory species that reliably distinguished decompensated NAFLD‐related cirrhosis (diagnostic accuracy, 0.97, 95% confidence interval [CI] 0.96–0.99). Diagnostic accuracy of the 13‐species signature remained high after adjustment for lactulose (area under the curve [AUC] 0.99) and rifaximin use (AUC 0.93). The discriminative ability of 13‐species metagenomic signature was robust in an independent test cohort (AUC 0.95, 95% CI 0.81–1.00). The 13‐species metagenomic signature (hazard ratio [HR] 1.54, 95% CI 1.10–2.15, p = 0.01) was a stronger predictor of mortality than the Model for End‐Stage Liver Disease score (HR 1.25, 95% CI 1.03–1.53, p = 0.03).ConclusionsThis study provides evidence for a gut metagenome‐derived signature with high diagnostic accuracy for hepatic decompensation that predicts risk of mortality in NAFLD‐related cirrhosis.

AbstractEctotherms thermoregulate to maintain their body temperature within the optimal range needed for performing vital functions. The effect of climate change on lizards has been studied as regards the sensitivity of locomotor performance to environmental temperatures. We studied thermoregulatory efficiency and locomotor performance for Liolaemus fitzgeraldi in the Central Andes of Argentina. We determined body temperature, micro‐environmental temperatures and operative temperatures in the field. In the laboratory, we measured preferred temperatures and calculated the index of thermoregulatory efficiency. We estimated the thermal sensitivity of locomotion by measuring sprint speed (initial velocity and long sprint) and endurance at five different body temperatures. Body temperature was not associated with either micro‐environmental temperature, nor did it show differences with preferred temperatures. Thermoregulatory efficiency was moderate (0.61). Initial velocity and long sprint trials showed differences at different temperatures; however, endurance did not. Moreover, the optimal temperatures for the performance trials showed no significant differences among themselves. We conclude that Liolaemus fitzgeraldi has thermal sensitivity in locomotor performance with respect to body temperature and that it is an eurythermic lizard that experiences a large variation in body temperature and that has thermal flexibility in the cold.

AbstractSince the first case of COVID‐19 was reported in December 2019, many studies have been carried out on artificial intelligence for the rapid diagnosis of the disease to support health services. Therefore, in this study, we present a powerful approach to detect COVID‐19 and COVID‐19 findings from computed tomography images using pre‐trained models using two different datasets. COVID‐19, influenza A (H1N1) pneumonia, bacterial pneumonia and healthy lung image classes were used in the first dataset. Consolidation, crazy‐paving pattern, ground‐glass opacity, ground‐glass opacity and consolidation, ground‐glass opacity and nodule classes were used in the second dataset. The study consists of four steps. In the first two steps, distinctive features were extracted from the final layers of the pre‐trained ShuffleNet, GoogLeNet and MobileNetV2 models trained with the datasets. In the next steps, the most relevant features were selected from the models using the Sine–Cosine optimization algorithm. Then, the hyperparameters of the Support Vector Machines were optimized with the Bayesian optimization algorithm and used to reclassify the feature subset that achieved the highest accuracy in the third step. The overall accuracy obtained for the first and second datasets is 99.46% and 99.82%, respectively. Finally, the performance of the results visualized with Occlusion Sensitivity Maps was compared with Gradient‐weighted class activation mapping. The approach proposed in this paper outperformed other methods in detecting COVID‐19 from multiclass viral pneumonia. Moreover, detecting the stages of COVID‐19 in the lungs was an innovative and successful approach.
