Physical activity recommendations pre and post abdominal wall reconstruction: a scoping review of the evidence.

PURPOSE: There are no universally agreed guidelines regarding which types of physical activity are safe and/or recommended in the perioperative period for patients undergoing ventral hernia repair or abdominal wall reconstruction (AWR). This study is intended to identify and summarise the literature on this topic. METHODS: Database searches of PubMed, CINAHL, Allied & Complementary medicine database, PEDro and Web of Science were performed followed by a snowballing search using two papers identified by the database search and four hand-selected papers of the authors' choosing. Inclusion-cohort studies, randomized controlled trials, prospective or retrospective. Studies concerning complex incisional hernia repairs and AWRs including a "prehabilitation" and/or "rehabilitation" program targeting the abdominal wall muscles in which the interventions were of a physical exercise nature. RoB2 and Robins-I were used to assess risk of bias. Prospero CRD42021236745. No external funding. Data from the included studies were extracted using a table based on the Cochrane Consumers and Communication Review Group's data extraction template. RESULTS: The database search yielded 5423 records. After screening two titles were selected for inclusion in our study. The snowballing search identified 49 records. After screening one title was selected for inclusion in our study. Three total papers were included-two randomised studies and one cohort study (combined 423 patients). All three studies subjected their patients to varying types of physical activity preoperatively, one study also prescribed these activities postoperatively. The outcomes differed between the studies therefore meta-analysis was impossible-two studies measured hernia recurrence, one measured peak torque. All three studies showed improved outcomes in their study groups compared to controls however significant methodological flaws and confounding factors existed in all three studies. No adverse events were reported. CONCLUSIONS: The literature supporting the advice given to patients regarding recommended physical activity levels in the perioperative period for AWR patients is sparse. Further research is urgently required on this subject.

Studies on in vitro antioxidant and antistaphylococcal activities of some important medicinal plants.

Oxidative stress is initiated by free radicals, which seek stability through electron pairing with biological macromolecules in healthy human cells and cause protein and DNA damage along with lipid peroxidation. Many phytochemicals have been found to play as potential antioxidants and antimicrobials. In the present study antioxidant and antistaphylococcal activities of Bauhinia variegata, Tinospora cardifolia and Piper longum have been determined. Total phenolic contents in plant extracts were estimated and different amounts of phenolic contents were found in B. variegata, T. cardifolia and P. longum extracts. The antioxidant activity of the extracts was compared with standard antioxidants such as, BHA, BHT, quercetin, ascorbic acid and propyl gallate. The % scavenging activity gradually increased with increasing concentrations of the test extracts in DPPH radical scavenging assay. Dose dependent antioxidant activity pattern was also observed in phosphomolybdate assay. Antioxidant activity was directly correlated with the amount of total phenolic contents in the extracts. As compared to B. variegata, the extracts from other two plants exhibited higher antioxidant activity. In disc diffusion assays several solvent extracts derived from test plants inhibited the growth of Staphylococcus aureus. Maximum inhibitory efficacy was observed in T. cardifolia extracts. However, the lowest minimum bactericidal concentration (MBC) (0.43 mg/ml) was recorded for ethyl acetate and acetone extracts of P. longum. This study demonstrates notable antioxidant and anti-staphylococcal roles assigned to some plant extracts tested.

Immobilization of sorghum leaf oxalate oxidase onto alkylamine and arylamine glass.

An oxalate oxidase (EC 1.2.3.4) purified from grain sorghum leaves was immobilized onto alkylamine and arylamine glass beads through glutaraldehyde coupling and diazotization with a conjugation yield of 10.8 mg/g support and 9.2 mg/g support, respectively. The enzyme retained 67.5% and 34.1% of its initial specific activity after immobilization onto alkylamine and arylamine glass, respectively. The enzyme exhibited an increase in optimum pH, temperature for maximum activity, energy of activation (Ea) and time for linearity but decrease in thermal stability at 60 degrees C after immobilization on both types of beads. The K(m) value for oxalate was increased by 9- to 10-fold but Vmax remained unaltered after immobilization. Both alkyl and arylamine glass bound enzyme was unaffected by physiological concentrations of Cl- and NO3-. The analytic importance of this work is demonstrated.

Profile and characteristics of animals bites in India.

Animal bites and so also the incidence of rabies in India are on rise. There are regional differences in the animal responsible for the bite. Different practices including use of traditional remedies are prevalent for wound treatment. In India this report analyses the profile and characteristics of animal bites in 869 patients from various regions. Apart from dog and cat, other animals such as cow, monkey, horse, pigs, camel were responsible for bite and could be possible vectors in transmission of rabies. Traditional remedies such as application of chilly paste is still practiced in state of Rajasthan.

ACUPUNCTURE AS AN ANTI-EMETIC IN MINOR GYNAECOLOGICAL SURGERY.

A study was undertaken to evaluate the effectiveness of acupuncture as an anti-emetic in patients undergoing minor gynaecological surgery. 100 patients were studied divided into study group (Group I) and control group (Group II) of 50 patients each. In group I patients, acupuncture needle was inserted at acupuncture point P6, 10 minutes before induction of anesthesia. In group II, no acupuncture was used. Anaesthetic technique was similar in both the groups. Five patients (10%) in group I and twenty (40%) in group II had one or more emetic episodes. These results show that acupuncture can be one of the modalities for the prevention of nausea and vomiting in postoperative period and its use as an anti-emetic should be explored further.

Plasma selenium levels in patients with advanced upper gastrointestinal cancer.

Plasma selenium levels were determined at various intervals during hospitalization of 71 patients with upper gastrointestinal and other malignancies. These patients often require frequent nutritional as well as surgical or medical intervention. Attempts were made to identify, evaluate, and compensate for numerous confounding variables at each of the 374 plasma selenium determinations. Selenium levels in stable patients who were neither receiving aggressive antineoplastic therapy, nor septic, nor taking corticosteroids and who had no clinically significant metabolic imbalance were then separately analyzed. In 55 stable patients selenium levels were 28% lower than those found in 20 normal controls (mean 61.8 micrograms/L, P less than 0.0005). An analysis of all the readings showed that selenium levels were substantially decreased by recent radiotherapy or sepsis, by regional tumor spread and increased tumor burden, and by intravenous and/or enteral hyperalimentation and intravenous lipids. In contrast to these findings, levels were relatively higher in patients with an adequate oral diet or with a lesser tumor burden. The comparison between selenium levels in stable and in aggressively treated or septic patients supports the importance of the relationship of nutrition to selenium levels in cancer patients.

Corticosteroid-like effects after high doses of compound (5-methoxy-2-thienyl)-thioacetic acid sodium salt in rats.

During a systemic tolerance study in rats with compound (5-methoxy-2-thienyl)-thioacetic acid sodium salt (MTTA), which is known to decrease the lipolytic process and platelet aggregation, effects after high doses were observed which are similar to the well-known findings after corticosteroid administration. The oral application of MTTA in a dose range from 10 to 1000 mg/kg over a period of 4 weeks resulted in a decrease in total lipids and free fatty acids from 100 mg/kg onwards and an increase in total glycerin and triglycerides after 1000 mg/kg, supplemented with an increased excretion of keto-bodies in urine at all dose levels. The hematological examinations revealed a reduction of blood eosinophils and lymphocytes in males at doses from 10 mg/kg, whereas the eosinophilic granulocytopoiesis was decreased only at the 1000 mg/kg level in both sexes. Determinations of organ weights showed a decrease in thymus weight from 300 mg/kg onwards with an involution at the highest dose levels, being confirmed by histological examination, whereas the adrenal glands' weights were decreased only at the dose level of 1000 mg/kg. Since the endogenous corticosterone level remained unaltered at all doses, it is suggested that these corticosteroid-like effects are directly attributable to MTTA.

Screening of antiserotoninergic drugs with the genetically dystrophic chicken.

Line 413 early-onset, genetically homozygous dystrophic chickens were given twice-daily intraperitoneal injections of the antiserotoninergic drugs p-chlorophenylalanine hydrochloride, fluoxetine hydrochloride, ergonovine maleate, nortriptyline hydrochloride, methiothepin maleate, and methysergide bimaleate in combination with penicillamine. Except in one case, treatment with drugs significantly prolonged the righting ability of the treated dystrophic chickens, as measured by a periodic standardized flip-test procedure. Abnormally high levels of plasma creatine phosphokinase, lactate dehydrogenase, and SGOT were found in the untreated dystrophic chickens. However, of the drug-treated dystrophic chickens, in some cases the plasma enzyme activities were reduced whereas in others they were enhanced. In agreement with previous findings, the blood serotonin levels of the dystrophic chickens were found at all age groups to be significantly higher than those in the corresponding normal chickens. This phenomenon may in part account for the improvement in righting ability demonstrated in the dystrophic chickens receiving treatment with antiserotoninergic drugs.
