Published: July 2021

Abstract
Background
Even though the importance of preparing patients for a surgical event is recognized, there are still gaps about the benefit of improving functional capacity by walking during the waiting time among patients scheduled for non-cardiac surgery. The aim of this study was to evaluate the impact of pre-surgical walking in-hospital length of stay, early ambulation, and the appearance of complications after surgery among patients scheduled for non-cardiac surgery.

Methods
A two-arm, single- blinded randomized controlled trial was developed from May 2016 to August 2017. Eligible outpatients scheduled for non-cardiac surgery, capable of walking, were randomized (2:1 ratio) to receive a prescription of walking 150 min/week during the whole pre-surgical waiting time (n = 249) or conventional care (n = 119). The primary outcome was the difference in hospital length of stay, and secondary results were time to first ambulation during hospitalization, description of ischemic events during hospitalization and after six months of hospital discharge, and the walking continuation. We performed an intention to treat analysis and compared length of stay between both groups by Kaplan–Meier estimator (log-rank test).

Results
There were no significant differences in the length of hospital stay between both groups (log-rank test p = 0.367) and no differences in the first ambulation time during hospitalization (log-rank test p = 0.299). Similar rates of postoperative complications were observed in both groups, but patients in the intervention group continued to practice walking six months after discharge (p < 0.001).

Conclusion
Our study is the first clinical trial evaluating the impact of walking before non-cardiac surgery in the length of stay, early ambulation, and complications after surgery. Prescription of walking for patients before non-cardiac surgery had no significant effect in reducing the length of stay, and early ambulation. The results become a crucial element for further investigation.

Plurihormonal pituitary macroadenoma: a case report
Authors: Allehaibi Ebtesam , AlMalki Mussa H. , Brema Imad 
Published: July 2021

Abstract
Background
Plurihormonal pituitary adenomas are a unique type of pituitary adenomas that secrete two or more pituitary hormones normally associated with separate cell types that have different immunocytochemical and ultrastructural features. Although they represent 10–15% of all pituitary tumors, only a small fraction of plurihormonal pituitary adenomas clinically secrete multiple hormones. The most common hormone combinations secreted by plurihormonal pituitary adenomas are growth hormone, prolactin, and one or more glycoprotein hormones. The most common hormonal symptom is acromegaly (50%). The aim of this case report is to bring awareness about this rare type of pituitary adenomas and to describe the unique presentation of our patient, even though plurihormonal pituitary adenomas are known mostly as a clinically silent tumors.

Case presentation
Herein, we describe an unusual case of plurihormonal pituitary adenoma with triple-positive staining for adrenocorticotropic hormone, growth hormone, and prolactin. The patient is a 65-year-old Egyptian woman who presented with mass effect symptoms of the pituitary tumor, which primarily manifested as severe headache and visual field defects. She also presented with some cushingoid features, and further analysis confirmed Cushing’s disease; slightly high prolactin and normal growth hormone levels were observed. She underwent transsphenoidal surgery and has been in remission thus far. Only a few cases have been reported in the literature, but none has exhibited silent acromegaly or mass effect symptoms as the initial presentation.

Conclusion
This case highlights an unusual plurihormonal pituitary adenoma case with a rare combination of secreted hormones; mass effect symptoms were dominant, as were uncommon visual field defects. Our case further proves that immunohistochemical analyses of all pituitary hormones are needed to ensure correct diagnosis and to alert clinicians to the need for more rigorous follow-up due to the higher morbidity of these patients. Our case report approval number Federal Wide Assurance NIH, USA is FWA00018774 IRB registration number with OHRP/NIH is IRB00010471.

AbstractMovement ecology is increasingly relying on experimental approaches and hypothesis testing to reveal how, when, where, why, and which animals move. Movement of megafauna is inherently interesting but many of the fundamental questions of movement ecology can be efficiently tested in study systems with high degrees of control. Lakes can be seen as microcosms for studying ecological processes and the use of high-resolution positioning systems to triangulate exact coordinates of fish, along with sensors that relay information about depth, temperature, acceleration, predation, and more, can be used to answer some of movement ecology’s most pressing questions. We describe how key questions in animal movement have been approached and how experiments can be designed to gather information about movement processes to answer questions about the physiological, genetic, and environmental drivers of movement using lakes. We submit that whole lake telemetry studies have a key role to play not only in movement ecology but more broadly in biology as key scientific arenas for knowledge advancement. New hardware for tracking aquatic animals and statistical tools for understanding the processes underlying detection data will continue to advance the potential for revealing the paradigms that govern movement and biological phenomena not just within lakes but in other realms spanning lands and oceans.

Published: July 2021

Abstract
Background
Psychological treatments are widely tested and have been effective in treating depressive symptoms. However, implementation of psychological treatments in the real world and in diverse populations remains difficult due to several interacting barriers. In this study, we assessed the acceptability and feasibility of peer-administered group interpersonal therapy for depressive symptoms among people living with HIV/AIDS in Northwest Ethiopia.

Method
We conducted a single-arm, peer-administered, group interpersonal therapy intervention with eight weekly sessions from 15 August to 15 December 2019 among people living with HIV/AIDS in Northwest Ethiopia. Four interpersonal therapy groups were formed for the intervention with a total of 31 participants.

Results
Of the 31 recruited participants, 29 completed the intervention providing a retention rate of 93.5%. The process of the intervention and its outcomes were highly acceptable as most participants expressed success in resolving their psychosocial problems, adjusting to life changes and coping with stigma. The intervention was also reported to be feasible despite anticipated barriers such as access to transportation, perceived stigma and confidentiality concerns. The post-intervention assessment revealed significant reduction in depressive symptoms (mean difference (MD) = 9.92; t =  − 7.82; 95% CI, − 12.54, − 7.31; p < 0.001), improvement in perceived social support (MD = 0.79; t = 2.84; 95% CI, 0.22, 1.37; p = 0.009) and quality of life (MD = 0.39; t = 4.58; 95% CI, 0.21, 0.56; p < 0.001).

Conclusion
Group interpersonal therapy is feasible and acceptable, and people living with HIV/AIDS can benefit from group interpersonal therapy in managing depressive symptoms and in improving perceived social support and quality of life. Future studies should examine the effectiveness of group interpersonal therapy in this setting.

Published: July 2021

AbstractRice beverages are traditionally prepared and consumed popularly by the different ethnic groups of North East India and claimed to have several health benefits. In an attempt to validate the traditional claims, effects of different fractions of the beverage were studied using mouse model. To investigate its effects on behavior, mice were treated with different fractions of rice beverage that included the beverage as a whole, insoluble and soluble fractions. Intragastric treatments of these fractions were given to the mice (n = 6 per group) for 30 days, and behavioral studies were performed on elevated plus and Y maze to evaluate anxiety and spatial memory, respectively. Next-generation sequencing of metagenomic DNA of the beverage indicated the presence of 157 OTUs, and 26 bacterial genera were dominant with an abundance of 0.1%. The insoluble fraction and the whole beverage treatments reduced the anxiety-like symptoms in animals indicating the probable role of microbes. Spatial memory improved in all the treatments compared to the control, of which the rice beverage treatment showed the highest levels (p < 0.05). Gas chromatography and mass spectroscopy-based metabolite profiling of the beverage revealed 10 alcohols, 29 sachharides, 43 acids, and 13 amino acids. Findings of this study suggest a positive effect of rice beverage on anxiety and spatial memory of mice, justifying the claims by ethnic communities on its role on mood regulation.
Impact of kinesiophobia on physical function and quality of life in functional ankle instability individuals: an observational study

Published: July 2021

Abstract
Background
Functional ankle instability is a common musculoskeletal condition affecting the community. It is characterized by repetitive bouts of giving away, recurrent sprains, and sensation of instability leading to functional deficits in an individual. The present study aimed to assess the influence of kinesiophobia on physical function and quality of life in participants with functional ankle instability. A cross-sectional study was conducted in 30 participants with functional ankle instability. Kinesiophobia was assessed using the 17-item Tampa Scale of Kinesiophobia, physical function using the Foot and Ankle Ability Measure (FAAM) and the FAAM-Sport version (FAAM-S), and quality of life using SF-36.

Results
The TSK score showed a moderate negative correlation with FAAM-S (r = −0.5, p = 0.005) and a weak negative correlation with SF-36 physical component summary (r = −0.42, p = 0.02). However, TSK showed no significant correlation with FAAM-ADL and SF-36 mental component summary.

Conclusion
Increased fear of movement, reduced physical function, and health-related quality of life were observed in functional ankle instability individuals. Hence, evaluation of these parameters is imperative in these individuals.

AbstractBackgroundCisplatin is a frontline anticancer drug routinely used as part of concurrent chemoradiation administered at 3-weekly (100 mg/m2) dose. However, its role as fractionated weekly dose has achieved favorable outcome in patients with locally advanced squamous cell carcinoma of head and neck (LA-SCCHN) during induction chemotherapy (IC). We therefore sought to compare the toxicity outcomes of patients with LA-SCCHN treated with platinum-based IC at a single institution study using split-dose cisplatin chemotherapy. We compared the hematological and renal toxicity profile between the weekly cisplatin (30 mg/m2) (group A) versus 3-weekly (100 mg/m2) (group B) dosage schedule in this setting.ResultsThe median age of the patients in groups A and B were 49.1 years and 48.27 years respectively with male:female ratio of 4:1. Most of the patients were of oropharyngeal cancers. Group A patients showed greater neutropenia (40.2%) than group B (20.6%). There was statistically significant fall in Hb% level in group A (13.9%) than in group B (11.9%). Renal profile showed greater rise in serum urea and serum creatinine (52.7%) in group B than in group A (52.29%) with statistically significant difference.ConclusionsSince toxicities induced by high-dose cisplatin are irreversible and reduce quality of life in patients, the weekly regimen may be preferred owing to less renal toxicity, lesser hospitalization and more feasible in situations with high patient load and limited resources.

AbstractThyrotropin (TSH), traditionally seen as a pituitary hormone that regulates thyroid glands, has additional roles in physiology including skeletal remodeling. Population-based observations in people with euthyroidism or subclinical hyperthyroidism indicated a negative association between bone mass and low-normal TSH. The findings of correlative studies were supported by small intervention trials using recombinant human TSH (rhTSH) injection, and genetic and case-based evidence. Genetically modified mouse models, which disrupt the reciprocal relationship between TSH and thyroid hormone, have allowed us to examine an independent role of TSH. Since the first description of osteoporotic phenotype in haploinsufficient Tshr+/– mice with normal thyroid hormone levels, the antiosteoclastic effect of TSH has been documented in both in vitro and in vivo studies. Further studies showed that increased osteoclastogenesis in Tshr-deficient mice was mediated by tumor necrosis factor α. Low TSH not only increased osteoclastogenesis, but also decreased osteoblastogenesis in bone marrow–derived primary osteoblast cultures. However, later in vivo studies using small and intermittent doses of rhTSH showed a proanabolic effect, which suggests that its action might be dose and frequency dependent. TSHR was shown to interact with insulin-like growth factor 1 receptor, and vascular endothelial growth factor and Wnt pathway might play a role in TSH’s effect on osteoblasts. The expression and direct skeletal effect of a biologically active splice variant of the TSHβ subunit (TSHβv) in bone marrow–derived macrophage and other immune cells suggest a local skeletal effect of TSHR. Further studies of how locally secreted TSHβv and systemic TSHβ interact in skeletal remodeling through the endocrine, immune, and skeletal systems will help us better understand the hyperthyroidism-induced bone disease.

AbstractDiabetes mellitus (DM) in children is most often caused by impaired insulin secretion (type 1 DM). In some children, the underlying mechanism for DM is increased insulin resistance, which can have different underlying causes. While the majority of these children require insulin dosages less than 2.0 U/kg/day to achieve normoglycemia, higher insulin requirements indicate severe insulin resistance. Considering the therapeutic challenges in patients with severe insulin resistance, early diagnosis of the underlying cause is essential in order to consider targeted therapies and to prevent diabetic complications. Although rare, several disorders can attribute to severe insulin resistance in pediatric patients. Most of these disorders are diagnosed through advanced diagnostic tests, which are not commonly available in low- or middle-income countries. Based on a case of DM with severe insulin resistance in a Surinamese adolescent who was later confirmed to have autosomal recessive congenital generalized lipodystrophy, type 1 (Berardinelli–Seip syndrome), we provide a systematic approach to the differential diagnosis and work-up. We show that a thorough review of medical history and physical examination generally provide sufficient information to diagnose a child with insulin-resistant DM correctly, and, therefore, our approach is especially applicable to low- or middle-income countries.

Abstract

Context
Severe forms of growth hormone insensitivity (GHI) are characterized by extreme short stature, dysmorphism, and metabolic anomalies.

Objective
This work aims to identify the genetic cause of growth failure in 3 “classical” GHI individuals.

Methods
A novel intronic growth hormone receptor gene (GHR) variant was identified, and in vitro splicing assays confirmed aberrant splicing. A 6Ω pseudoexon GHR vector and patient fibroblast analysis assessed the consequences of the novel pseudoexon inclusion and the impact on GHR function.

Results
We identified a novel homozygous intronic GHR variant (g.5:42700940T &gt; G, c.618+836T &gt; G), 44 bp downstream of the previously recognized intronic 6Ψ GHR pseudoexon mutation in the index patient. Two siblings also harbored the novel intronic 6Ω pseudoexon GHR variant in compound heterozygosity with the known GHR c.181C &gt; T (R43X) mutation. In vitro splicing analysis confirmed inclusion of a 151-bp mutant 6Ω pseudoexon not identified in wild-type constructs. Inclusion of the 6Ω pseudoexon causes a frameshift resulting in a nonfunctional truncated GHR lacking the transmembrane and intracellular domains. The truncated 6Ω pseudoexon protein demonstrated extracellular accumulation and diminished activation of STAT5B signaling following GH stimulation.

Conclusion
Novel GHR 6Ω pseudoexon inclusion results in loss of GHR function consistent with a severe GHI phenotype. This represents a novel mechanism of Laron syndrome and is the first deep intronic variant identified causing severe postnatal growth failure. The 2 kindreds originate from the same town in Campania, Southern Italy, implying common ancestry. Our findings highlight the importance of studying variation in deep intronic regions as a cause of monogenic disorders.
Preproglucagon Products and Their Respective Roles Regulating Insulin Secretion

Published: July 2021

Abstract
Historically, intracellular function and metabolic adaptation within the α-cell has been understudied, with most of the attention being placed on the insulin-producing β-cells due to their role in the pathophysiology of type 2 diabetes mellitus. However, there is a growing interest in understanding the function of other endocrine cell types within the islet and their paracrine role in regulating insulin secretion. For example, there is greater appreciation for α-cell products and their contributions to overall glucose homeostasis. Several recent studies have addressed a paracrine role for α-cell–derived glucagon-like peptide-1 (GLP-1) in regulating glucose homeostasis and responses to metabolic stress. Further, other studies have demonstrated the ability of glucagon to impact insulin secretion by acting through the GLP-1 receptor. These studies challenge the central dogma surrounding α-cell biology describing glucagon’s primary role in glucose counterregulation to one where glucagon is critical in regulating both hyper- and hypoglycemic responses. Herein, this review will update the current understanding of the role of glucagon and α-cell–derived GLP-1, placing emphasis on their roles in regulating glucose homeostasis, insulin secretion, and β-cell mass.
The Src-family Kinase Lyn in Immunoreceptor Signaling
Authors: Brian Ben F , Freedman Tanya S 
Published: July 2021

AbstractEffective regulation of immune-cell activation is critical for ensuring that the immune response, and inflammation generated for the purpose of pathogen elimination, are limited in space and time to minimize tissue damage. Autoimmune disease can occur when immunoreceptor signaling is dysregulated, leading to unrestrained inflammation and organ damage. Conversely, tumors can coopt the tissue healing and immunosuppressive functions of hematopoietic cells to promote metastasis and evade therapy. The Src-family kinase Lyn is an essential regulator of immunoreceptor signaling, initiating both proinflammatory and suppressive signaling pathways in myeloid immune cells (eg, neutrophils, dendritic cells, monocytes, macrophages) and in B lymphocytes. Defects in Lyn signaling are implicated in autoimmune disease, but mechanisms by which Lyn, expressed along with a battery of other Src-family kinases, may uniquely direct both positive and negative signaling remain incompletely defined. This review describes our current understanding of the activating and inhibitory contributions of Lyn to immunoreceptor signaling and how these processes contribute to myeloid and B-cell function. We also highlight recent work suggesting that the 2 proteins generated by alternative splicing of lyn, LynA and LynB, differentially regulate both immune and cancer-cell signaling. These principles may also extend to other Lyn-expressing cells, such as neuronal and endocrine cells. Unraveling the common and cell-specific aspects of Lyn function could lead to new approaches to therapeutically target dysregulated pathways in pathologies ranging from autoimmune and neurogenerative disease to cancer.
