Published: December 2022

PurposeThe current study aims to map the scientific output of grey literature (GL) through bibliometric approaches.Design/methodology/approachThe source for data extraction is a comprehensive “indexing and abstracting” database, “Web of Science” (WOS). A lexical title search was applied to get the corpus of the study – a total of 4,599 articles were extracted for data analysis and visualisation. Further, the data were analysed by using the data analytical tools, R-studio and VOSViewer.FindingsThe findings showed that the “publications” have substantially grown up during the timeline. The most productive phase (2018–2021) resulted in 47% of articles. The prominent sources were PLOS One and NeuroImage. The highest number of papers were contributed by Haddaway and Kumar. The most relevant countries were the USA and UK.Practical implicationsThe study is useful for researchers interested in the GL research domain. The study helps to understand the evolution of the GL to provide research support further in this area.Originality/valueThe present study provides a new orientation to the scholarly output of the GL. The study is rigorous and all-inclusive based on analytical operations like the research networks, collaboration and visualisation. To the best of the authors' knowledge, this manuscript is original, and no similar works have been found with the research objectives included here.
Tax amnesty schemes, anti-money laundering regulations and customer due diligence by financial institutes: an evaluation of the implementation issues in Pakistan
Authors: Sultan Nasir , Mohamed Norazida , Hussain Dildar 
Published: December 2022

Purpose
Tax amnesty (TA) schemes are typical in developing countries. Governments’ claims and suppositions are continually heightened; however, this may differ in actuality. This study aims to present an overview of the effectiveness of TA schemes and the problems they raise in implementing anti-money laundering regulations.

Design/methodology/approach
This study used a qualitative research design. Content analysis was used to analyse research articles, reports, legal documents and news articles.

Findings
Every amnesty offered in Pakistan from 1956 to 2018 failed to meet government expectations. Instead, the continuity resulted in an irrepressible black economy. The black economy’s uncontrollability undermines tax collection and hinders a robust anti-money laundering regime. Significantly, tax holidays with discrepant legislation strengthen evaders, plunderers and launderers. These policies severely impede the implementation of anti-money laundering policies in the financial institutions of Pakistan. Additionally, Pakistan's geopolitical location, circumstance and war against terror cannot afford any policy that provides monetary relaxation to offenders.

Practical implications
There is no concrete evidence to support long-term economic progress through the implementation of amnesty schemes as a revenue collection policy. This study evaluates previous studies and findings to understand the effect of tax amnesties on the financial industry of Pakistan. The findings have practical implications for tax collection authorities, policymakers and international financial bodies.

Originality/value
Previous studies have discussed the advantages and disadvantages of Pakistan’s regular tax amnesties. However, this study discusses the implementation of TA schemes concerning anti-money laundering regulations and customer due diligence by financial institutes and provides suggestions to minimise its negative implications.

Authors: Sood Kirti , Arijit Kumar , Pathak Prachi , Purohit H.C. 
Published: December 2022

Purpose
This paper aims to empirically examine the performance of the high-ESG (environment, social and governance) portfolio vis-à-vis the low-ESG portfolio at the Indian stock market before and during the Covid19 pandemic.

Design/methodology/approach
The absolute rate of return and several risk-adjusted performance measures, for instance, Sharpe ratio, Modigliani–Modigliani measure, Treynor ratio, Jensen’s alpha, information ratio, Fama’s decomposition measure and Fama and French’s three-factor model, have been used in this study along with the t-test.

Findings
All three indices (CARBONEX, GREENEX and BSE 500) had better returns during Covid19 period as compared to the pre-Covid19 period. However, these returns were not statistically significant. During Covid19, the risk of the indices also rose, but they provided better returns for the additional risk taken. Finally, it is concluded that the performance of high-ESG and low-ESG stock portfolios did not differ significantly in both periods.

Practical implications
The study is relevant to individual and institutional investors, financial advisors, portfolio managers, corporations, policymakers, market regulators and society at large.

Social implications
This study emphasized the need to expand the role of ESG investment in India for the benefit of people, communities and society as a whole.

Originality/value
This research is the first of its kind, to the best of the authors’ knowledge, that compares the performance of a high-ESG portfolio with a low-ESG portfolio both before and during the Covid19, particularly in the Indian context.

AbstractBackgroundLeft ventricular assist device (LVAD) implantation is frequently employed in patients with end‐stage heart failure. The outcomes of addressing the repair of all substantial aortic valvular disease at the time of LVAD implantation remain unclear. We sought to assess the clinical outcomes in patients undergoing LVAD implantation concomitant with aortic valve procedures (AVPs) compared with isolated LVAD implantation.MethodsA literature search was performed using PubMed, Embase, and Cochrane library from inception till June 2022. Primary outcomes included short‐term mortality and long‐term survival. Random effects models were used to compute mean differences and odds ratios with 95% confidence intervals (CIs).ResultsA total of 14 observational studies (N = 52 693) met our inclusion criteria. Concomitant LVAD implantation and AVPs were associated with higher short‐term mortality (OR = 1.61 [95% CI, 1.06–2.42]; p = 0.02) and mean CPBt (MD = 43.25 [95% CI, 22.95–63.56]; p < 0.0001), and reduced long‐term survival (OR = 0.70 [95% CI, 0.55–0.88]; p = 0.003) compared with isolated LVAD implantation. No difference in the odds of cerebrovascular accident (OR = 1.05 [95% CI, 0.79–1.39]; p = 0.74) and mean length of hospital stay (MD = 2.89 [95% CI, −4.04 to 9.82]; p = 0.41) was observed between the two groups. On adjusted analysis, short‐term mortality was significantly higher in the LVAD group with concurrent AVPs when compared with the isolated LVAD group (aHR = 1.50 [95% CI, 1.20–1.87]; p = 0.0004).ConclusionsConcurrent AVPs were associated with higher short‐term mortality and reduced long‐term survival in patients undergoing LVAD implantation compared with isolated LVAD implantation.

Published: December 2022

AbstractPurposeThe purpose of the study was to assess the association of macular atrophy (MA) according to the activity of macular neovascularization (MNV) (inactive, only subretinal fluid [SRFL], or active, i.e. including intraretinal fluid [IRFL]) using optical coherence tomography (OCT) in patients with neovascular age‐related macular degeneration (nAMD).MethodsMulticentric observational study. Treatment‐naïve nAMD eyes without subfoveal MA or subretinal fibrosis (SF) at baseline were included since 1st January 2010 and 30th September 2016 to allow up to 5 years of treatment follow‐up. Eyes were grouped based on their predominant activity status as: (1) mostly inactive, (2) mostly active non‐SRFL only [IRFL] or (3) mostly active‐SRFL only [onlySRFL]. Kaplan–Meier survival curves estimated the time to development of MA or SF. Cox proportional hazards models evaluated predictors of developing subfoveal MA or SF. The main outcome measure was the risk of developing MA according to predominant MNV activity.ResultsA total of 973 eyes were eligible for analysis. OnlySRFL eyes had lower risk of developing subfoveal MA (HR [95% CI]: 0.56 [0.36, 0.88]; p = 0.024) and extrafoveal MA (HR [95% CI]: 0.41 [0.27, 0.61]; p < 0.001) than IRFL eyes. IRFL eyes had lower visual acuity (VA) (54.5 letters) and the highest proportion of eyes with vision ≤35 letters (25%) at 5 years while onlySRFL eyes had comparable 5‐year VA (63.7 letters) to inactive eyes (63.7 letters).ConclusionSubretinal fluid appears to protect against MA. Distinguishing the compartment of retinal fluid and understanding its relationship with MA and SF can guide the management of nAMD.

Published: December 2022

AbstractDelayed surgical reconstruction of iatrogenic ureteral injuries is often a challenging procedure because spreading scar tissue impedes accurate identification and dissection of the injured ureter. We report a novel real‐time navigation system using a ureteral near‐infrared ray catheter (NIRC) and indocyanine green (ICG) via nephrostomy in delayed robot‐assisted ureteral reconstruction. A female patient presented with complete obstruction of the right upper ureter after gynecological surgery with extensive lymphadenectomy. A nephrostomy tube was urgently placed, and surgical repair was performed. A straight NIRC was placed in the right ureter up to the obstruction point. ICG was administered via nephrostomy. Near‐infrared light could clearly visualize the ureter and renal pelvis encased in scar tissue. The ureter and renal pelvis were dissected and successfully anastomosed. We found that near‐infrared navigation using ureteral NIRC and ICG via nephrostomy was valuable for delayed laparoscopic reconstruction of the injured ureter.

AbstractBackground and PurposeA major problem managing alcohol use disorder is the high vulnerability to relapse, even after long periods of abstinence. Chronic alcohol use dysregulates stress responsivity, rendering this system hyporesponsive and making individuals vulnerable to relapse. Orexin (hypocretin) plays a role in diverse physiological processes, including stress. Orexin neurons in the hypothalamus, project to the infralimbic cortex. This study asked does infralimbic cortex orexin transmission play a significant role in stress‐induced reinstatement of alcohol‐seeking behaviour in alcohol‐dependent rats.Experimental ApproachMale and female rats were trained to self‐administer 10% alcohol (3 weeks) and then made dependent via chronic intermittent alcohol vapour exposure. Following extinction (5 days·week−1 at 8 h abstinence for 10 sessions), rats received an intra‐ infralimbic cortex microinfusion of the OX1/2 antagonist TCS 1102 (15 μg/0.5 μl per side) and then tested for footshock stress‐induced reinstatement of alcohol seeking. In a separate cohort, orexin regulation of infralimbic cortex neuronal activity at the time of reinstatement was investigated using ex vivo electrophysiology.Key ResultsTCS 1102 prevented reinstatement in dependent animals only. Moreover, Hcrtr mRNA expression in the hypothalamus and Hcrtr1/2 in the infralimbic cortex increased in alcohol‐dependent animals at the time of testing. Dependence dampened basal orexin/OX receptor influence over infralimbic cortex GABAergic synapses (using TCS 1102) allow for greater stimulated orexin effects.Conclusion and ImplicationsInfralimbic cortex transmission is implicate in stress‐induced reinstatement of alcohol‐seeking behaviour in subjects with a history of alcohol dependence and show maladaptive recruitment of infralimbic cortex transmission by alcohol dependence.

Published: December 2022

AbstractBackgroundPrevious studies focused on the influence of buccal mucosa thickness on peri‐implant bone loss and inflammation, with inconclusive results. We observed substantially thicker palatal mucosal tissues at peri‐implantitis sites. Therefore, we hypothesize that thick palatal peri‐implant mucosa may be associated with deeper pockets and disease severity.PurposeTo compare the thickness of the palatal tissue between natural teeth and implants in periodontal health and disease.MethodsAdult, non‐smoker, healthy patients who visited our department for periodontal examination or treatment with restored implants in the posterior maxilla were recruited. Probing depth (PD), plaque index (PI), gingival index (GI) and radiographic measurements were recorded around implant and the contralateral tooth. Palatal tissue thickness was measured using a 30G needle that was inserted perpendicular into the mucosa at the bottom of the periodontal/peri‐implant pocket and 3 mm coronally. Differences in the palatal tissue thickness between teeth and implants (in the same patient) was performed using t‐test; as well as between peri‐implantitis and non‐peri‐implantitis sites (among patients).ResultsSixty patients were included. Thirty‐four implants were diagnosed with peri‐implantitis and 26 healthy/mucositis implants with corresponding 24 healthy/gingivitis teeth and 36 teeth with attachment loss. Mean PD was higher around implants (4.47 ± 1.57 mm) than teeth (3.61 ± 1.23 mm, p = 0.001). The thickness of implants' palatal mucosa was higher than in teeth, at the base of the pocket and 3 mm coronally (4.58 ± 1.38 mm vs. 3.01 ± 1.11, p = 0.000; 3.58 ± 2.15 vs. 1.89 ± 1.11, p = 0.000, respectively). Mean palatal tissue thickness was 4.32 ± 2.35 mm for the peri‐implantitis group while only 2.61 ± 1.39 in healthy implants, 3 mm coronal to the base of the pocket (p = 0.001). Palatal thickness at peri‐implantitis sites was higher (4.32 ± 2.35) compared to periodontitis sites (2.23 ± 0.93), p = 0.000. Implant sites with palatal mucosa >4 mm (n = 32) had deeper mean pockets (5.58 ± 1.98) compared with thinner (≤4 mm) sites (n = 28) (4.48 ± 1.18, p = 0.018).ConclusionThicker palatal tissue around implants is associated with deeper palatal pockets. Thick palatal tissue was found around implants diagnosed with peri‐implantitis.
Safety of different surgical modalities for recurrent respiratory papillomatosis resection: A systematic review and meta‐analysis
Authors: Liu Siwei , Wang Jiaqi , Shao Jun 
Published: December 2022

AbstractBackgroundCurrently, the most common surgical modalities used for recurrent respiratory papillomatosis (RRP) resection are microdebrider, carbon dioxide (CO2) laser and potassium‐titanyl‐phosphate (KTP) laser. However, complication rates vary among different surgical modalities and have been controversial in different studies.Objective of ReviewThis study systematically reviews the available studies which reported intra‐operative and post‐operative complications, aiming to compare the safety of microdebrider, CO2 laser and KTP laser.Type of ReviewMeta‐analysis.Search StrategySeven electronic databases (PubMed/MEDLINE, EMBASE[Ovid], Scopus, Cochrane Library and Web of Science) were searched from inception through 28 April 2022. Randomised controlled, prospective or retrospective observational studies that recorded the complications of three different surgical modalities for RRP resection were included in the meta‐analysis.Evaluation MethodOutcomes of interest were intra‐operative and post‐operative complications, and complication rate was calculated to evaluate the safety of surgical methods.ResultsTwenty different studies were included in quantitative synthesis. Only one study compared outcomes of those three kinds of treatment modalities simultaneously, two studies compared microdebrider and CO2 laser, and the remaining studies focussed on only one of three treatments. The weighted average complication rate for microdebrider was 0.03 (95% confidence interval [CI] 0.00–0.21), n = 6, for CO2 laser treatment was 0.16 (95% CI 0.09–0.25), n = 14 and for KTP laser treatment was 0.04 (95% CI 0.00–0.14), n = 4.ConclusionThe limited evidence demonstrated that CO2 lasers in the surgical treatment of RRP may lead to more surgical complications, and microdebrider and KTP lasers may be safer. However, the heterogeneous data limit any strong comparison of outcomes of different treatment of laryngeal papillomas. Future randomised controlled trials that directly compare the safety of different surgical modalities are needed.
‘We tend to prioritise others and forget ourselves’: How women's caregiving responsibilities can facilitate or impede diabetes self‐management

Published: December 2022

AbstractAimThe objective of the parent study was to examine attitudes and experiences regarding counselling about preconception care among Black and/or Latina women in the United States with type 2 diabetes (T2DM). Here, we present emergent findings from a secondary analysis of caregiving.MethodsIn this qualitative descriptive study, we used conventional content analysis to identify themes from semi‐structured interviews with 32 Black and/or Latina women ages 18–40 who have T2DM in the United States recruited from online platforms and snowball sampling.ResultsCaregiving responsibilities both motivate and disrupt diabetes self‐management behaviours. Caregiving largely meant taking care of children, but women also had responsibilities to adult family members and romantic partners. Women were motivated to manage their diabetes in order to prevent negative health effects on their children and to stay healthy so they could fulfil caregiving responsibilities. However, caregiving competed for time, energy and money with self‐management. Struggling to balance caregiving and self‐management caused stress that women felt was intrinsically unhealthy and undermined self‐management.ConclusionsYoung adult women with T2DM identified different ways that the roles and responsibilities in the family could affect their diabetes self‐management. Providers and policymakers should develop health‐promoting interventions that accommodate caregiving responsibilities.
The latitudinal gradient of functional diversity of Miocene marine mollusks from Chile

Published: December 2022

Understanding latitudinal variations in biodiversity is central for biogeography. Along the coasts of the Southeast Pacific, several taxa show inverse latitudinal patterns of biodiversity, i.e. increasing species numbers from lower to higher latitudes. A plausible explanation for these patterns is that fjords, formed during the Pleistocene glaciations, increased the diversity of available biotopes that allowed for higher diversity in high latitudes. Assessing this hypothesis requires us to analyze latitudinal patterns of functional diversity (which is intimately related to niche use) in the absence of fjords, i.e. earlier than their formation. Here we test if the fossil record before the generation of fjords shows higher functional diversity at lower than at higher latitudes (a ‘regular' functional diversity gradient).We analyzed four components of functional diversity (functional richness, functional divergence, functional dispersion and functional evenness) for a fossil marine mollusk fauna from the lower Miocene (~18 million years ago) across four regions spanning more than 10 latitudinal degrees of the Chilean coast (between ~34°S and 45°S).The functional richness of gastropods and bivalves decreased non‐linearly from low to high latitudes. Contrarily, the functional evenness of gastropods remained relatively constant across the region and that of bivalves peaked at 45°S. The functional divergence and functional dispersion of taxonomic groups did not exhibit clear patterns of latitudinal variation. The multivariate analysis uncovered non‐linear latitudinal patterns in the abundance of functional groups (gastropods and bivalves), with the largest abundance towards lower latitudes.These results suggest that the niche breadth of mollusk assemblages might have decreased with latitude in the lower Miocene. This work can shed light on the mechanisms underlying the latitudinal variation of diversity observed today, offering a better understanding of how these patterns changed over time.
Extracellular traps formation following cervical spinal cord injury

Published: December 2022

AbstractSpinal cord injuries involve a primary injury that can lead to permanent loss of function and a secondary injury associated with pathologic and inflammatory processes. Extracellular traps are extracellular structures expressed by immune cells that are primarily composed of chromatin, granular enzymes and histones. Extracellular traps are known to induce tissue damage when overexpressed and could be associated in the occurrence of secondary damage. In the present study, we used flow cytometry to demonstrate that at 1 day following a C2 spinal cord lateral hemisection in male Swiss mice, resident microglia form vital microglia extracellular traps, and infiltrating neutrophils form vital neutrophil extracellular traps. We also used immunolabelling to show that microglia near the lesion area are most likely to form these microglia extracellular traps. As expected, infiltrating neutrophils are located at the site of injury, though only some of them engage in post‐injury extracellular trap formation. We also observed the formation of microglia and neutrophil extracellular traps in our sham animal models of durotomy, but formation was less frequent than following the C2 hemisection. Our results demonstrate for the first time that microglia form extracellular traps in the spinal cord following injury and durotomy. It remains however to determine the exact mechanisms and kinetics of neutrophil and microglia extracellular traps formation following spinal cord injury. This information would allow to better mitigate this inflammatory process that may contribute to secondary injury and to effectively target extracellular traps to improve functional outcomes following spinal cord injury.
