Abstract
This study aimed to explore patients' perspectives on the adoption of a prehabilitation multimodal online program. Patients recovering from gastrointestinal cancer surgery at a tertiary hospital between October 2021 and November 2022 were invited to participate. An e-Health program including intensity exercises, nutrition and psychological counselling was used. Patients were instructed to navigate the e-Health program over 24 h using an iPad and then complete the study survey. Patients' characteristics, use of technology, views and minimal expected outcomes from a preoperative online program were collected. Of the 30 patients included, most were female, most reported confidence in the use of technology, most considered the online program safe and most agreed it would be beneficial for their health. "Poor preoperative health" and "lack of motivation and encouragement" were identified as the main barriers to the uptake of a preoperative online program, while program 'simplicity' and perceived 'benefits' were the main facilitators. Significant improvement in postoperative outcomes is perceived to influence patients' willingness to participate in a preoperative multimodal e-Health program. Gastrointestinal cancer patients perceived the adoption of a preoperative multimodal e-Health application as safe to be performed at home and of potential benefit to their health. A range of patient's characteristics, barriers and facilitators to the uptake of an online program were identified. These should be considered in future preoperative multimodal online programs to enhance patient experience, adherence and efficacy. The safety and efficacy of the online prehabilitation program will need to be determined in a larger randomized controlled trial.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Severe Acute Respiratory Syndrome (SARS) due to the novel coronavirus has become the highest priority that threatens human health. This situation demands widespread vaccination and the innovation of new therapeutic methods. Despite drug discoveries, the need for approving new medicaments is felt because of adverse effects and lack of efficacy. Several medicinal plants including Viola odorata L. are recommended in traditional Persian medicine for alleviating respiratory infection symptoms. Recent studies showed anti-inflammatory, antioxidant, anti-asthmatic, antitussive, analgesic, and antibacterial activities of sweet violet. These enhance respiratory functions, reduce pulmonary inflammation, and decline mucous membrane edema. This study aimed to evaluate the efficacy of sweet violet syrup in alleviating the manifestations of COVID-19 infection. MATERIAL AND METHODS A randomized parallel-group double-blind controlled trial was conducted at Al-Zahra general hospital, Isfahan, Iran. A total of 108 outpatients were enrolled in the study. The patients were randomly allocated to intervention and placebo groups, with 54 patients in each group. The allocation was concealed using sealed opaque envelopes. The intervention group received violet syrup and the control group received placebo syrup, an add-on to the conventional treatment. The outcomes were COVID-19 manifestations, such as dyspnea, cough, myalgia, headache, and diarrhea, considered as outcomes of the study and were evaluated twice using a visual analog scale before the intervention and after 7 days, at the end of the study. Patients were followed daily by phone calls to monitor proper drug consumption and possible side effects. RESULTS No significant difference was between groups regarding demographic characteristics and vital signs before and after the treatment. Although all symptoms have improved significantly in both groups, patients who received violet syrup recovered faster and the mean severity scores of cough (P = 0.025), myalgia (P = 0.036), headache (P = 0.037), and diarrhea (P = 0.044) decreased greater in comparison to control group. CONCLUSION This study, the first clinical trial on the effectiveness of Viola odorata on SARS-CoV-2 patients, showed that Viola odorata L. effectively controls prevalent manifestations of COVID-19 including cough, myalgia, headache, and diarrhea. Regarding this survey, the violet syrup can be mentioned as a complementary treatment for viral influenza-like infections in which cough, myalgia, headache, and diarrhea are prominent.

Abstract
Persian medicine has recommended clinical experiences and proper herbal remedies for prevention and treatment of microbial infections and respiratory diseases. An open-label, randomized, controlled, multicenter trial was conducted at five hospitals in Tehran and Isfahan provinces of Iran on 358 hospitalized adult patients. A total of 174 patients received standard care and 184 received herbal remedies (polyherbal decoction every 8 hr and two herbal capsules every 12 hr) plus standard care for 7 days. The primary clinical endpoint was the duration of hospital stay, and secondary outcomes were clinical improvement of symptoms based on self-assessment questionnaire. Results demonstrated that these natural decoction and capsules treatment plus routine care significantly decreased duration of hospital dyspnea (3.291 day vs. 6.468 days), accelerated clinical improvement, and decreased symptoms such as dry cough, dyspnea, muscle pain, headache, fatigue, anorexia, chills, runny nose, sputum cough, and vertigo in the treatment group compared with standard-care group. Significant effects of these polyherbal formulations on improving the symptoms of COVID-19 could be incredibly promising for managing this pandemic with acceptable tolerability.

Molecular Signaling Interactions and Transport at the Osteochondral Interface: A Review.
Oliveira Silva, M, Gregory, JL, Ansari, N, Stok, KS
Frontiers in cell and developmental biology. 2020;:750
Abstract
Articular joints are comprised of different tissues, including cartilage and bone, with distinctive structural and mechanical properties. Joint homeostasis depends on mechanical and biological integrity of these components and signaling exchanges between them. Chondrocytes and osteocytes actively sense, integrate, and convert mechanical forces into biochemical signals in cartilage and bone, respectively. The osteochondral interface between the bone and cartilage allows these tissues to communicate with each other and exchange signaling and nutritional molecules, and by that ensure an integrated response to mechanical stimuli. It is currently not well known how molecules are transported between these tissues. Measuring molecular transport in vivo is highly desirable for tracking cartilage degeneration and osteoarthritis progression. Since transport of contrast agents, which are used for joint imaging, also depend on diffusion through the cartilage extracellular matrix, contrast agent enhanced imaging may provide a high resolution, non-invasive method for investigating molecular transport in the osteochondral unit. Only a few techniques have been developed to track molecular transport at the osteochondral interface, and there appear opportunities for development in this field. This review will describe current knowledge of the molecular interactions and transport in the osteochondral interface and discuss the potential of using contrast agents for investigating molecular transport and structural changes of the joint.

Abstract
UNLABELLED Acute kidney injury (AKI) is common in patients with cirrhosis and associated with significant mortality. The most common etiologies of AKI in this setting are prerenal azotemia (PRA), acute tubular necrosis (ATN), and hepatorenal syndrome (HRS). Accurately distinguishing the etiology of AKI is critical, as treatments differ markedly. However, establishing an accurate differential diagnosis is extremely challenging. Urinary biomarkers of kidney injury distinguish structural from functional causes of AKI and may facilitate more accurate and rapid diagnoses. We conducted a multicenter, prospective cohort study of patients with cirrhosis and AKI assessing multiple biomarkers for differential diagnosis of clinically adjudicated AKI. Patients (n = 36) whose creatinine returned to within 25% of their baseline within 48 hours were diagnosed with PRA. In addition, 76 patients with progressive AKI were diagnosed by way of blinded retrospective adjudication. Of these progressors, 39 (53%) patients were diagnosed with ATN, 19 (26%) with PRA, and 16 (22%) with HRS. Median values for neutrophil gelatinase-associated lipocalin (NGAL), interleukin-18 (IL-18), kidney injury molecule-1 (KIM-1), liver-type fatty acid binding protein (L-FABP), and albumin differed between etiologies and were significantly higher in patients adjudicated with ATN. The fractional excretion of sodium (FENa) was lowest in patients with HRS, 0.10%, but did not differ between those with PRA, 0.27%, or ATN, 0.31%, P = 0.54. The likelihood of being diagnosed with ATN increased step-wise with the number of biomarkers above optimal diagnostic cutoffs. CONCLUSION Urinary biomarkers of kidney injury are elevated in patients with cirrhosis and AKI due to ATN. Incorporating biomarkers into clinical decision making has the potential to more accurately guide treatment by establishing which patients have structural injury underlying their AKI. Further research is required to document biomarkers specific to HRS.

Abstract
BACKGROUND & OBJECTIVES Pentavalent antimony compounds are the first line of drugs in the treatment of cutaneous leishmaniasis. However, because of their potential toxic effects, many investigations are performed to find an effective and safe treatment for cutaneous leishmaniasis patients. Our objective in this investigation was to compare the effect of oral omeprazole and low dose systemic meglumine antimoniate (MA) and standard dose of systemic MA in the treatment of cutaneous leishmaniasis. METHODS This was a randomized double-blinded clinical trial. In 150 patients with cutaneous leishmaniasis who were randomly divided into three groups and were treated with: (i) MA 60 mg/kg/day/ IM and oral placebo for three weeks; (ii) MA 30 mg/kg/day/IM and oral omeprazole 40 mg/day for three weeks; and (iii) MA 30 mg/kg/day/IM and oral placebo for three weeks. All the patients were visited every two weeks from the beginning of the trial up to six weeks and then at 8 and 12 weeks. The effectiveness of the treatment was classified in three levels as complete response, partial response and no response. Data were analyzed by SPSS 10 using KI square, Mann-Whitney, Kaplan-Mayer and ANOVA tests. RESULTS Rate of complete response for three months (12 weeks) after starting the treatments was 93% for the group treated with standard dose of glucantime and placebo, 89% for the group treated with omeprazole and low dose glucantime and 80% for the group treated with low dose glucantime and placebo and these differences were significant (p < 0.05). The highest response rate was for the group treated with standard dose of glucantime and placebo. INTERPRETATION & CONCLUSION Although oral omeprazole and low dose of systemic MA showed less efficacy in comparison to standard dose of systemic MA in the treatment of cutaneous leishmaniasis, it still can be considered as a replacement therapy in high risk patients (such as patients with heart, kidney and/or liver disease) under close supervision of physician.
