RESUMEN

OBJECTIVE: To determine effects of postural and kinesthetic awareness on plantar pressure and static standing stability in chronic stroke patients. METHODS: The cross-sectional single-blind study was conducted at the University of Lahore Teaching Hospital, Lahore, Pakistan, from January 19 to March 2, 2023, and comprised stroke patients of both genders. aged 45-60 years having visual spatial neglect. They were randomised into control group A and experimental group B. Group A received routine physical therapy, while group B additionally received postural and kinesthetic awareness sessions. Static component of the Berg balance scale was used to measure balance, and PoData Stabiliometeric plate ("Chinesport, Italy") to measure plantar pressure. Data was analysed using SPSS version 25. RESULTS: Of the 52 patients, 26(50%) were in group A with mean age 51.97±4.37 years and mean weight 79.48±5.7kg. The remaining 26(50%) patients were in group B with mean age 50.69±4.41 years and mean weight 78.27±4.55kg. The outcome measures were significantly better in group B compared to group A (p<0.05). CONCLUSIONS: Postural and kinesthetic awareness could possibly be a well-grounded rehabilitative strategy that may support and enhance the balance of individuals with chronic stroke. Clinical Trial Number: The study was registered at the United States National Institutes of Health (ClinicalTrials.gov) with registration number NCT05915195.

RESUMEN

The influence of boundary layer flow of heat transfer analysis on hybrid nanofluid across an extended cylinder is the main focus of the current research. In addition, the impressions of magnetohydrodynamic, porous medium and thermal radiation are part of this investigation. Arrogate similarity variables are employed to transform the governing modelled partial differential equations into a couple of highly nonlinear ordinary differential equations. A numerical approach based on the BVP Midrich scheme in MAPLE solver is employed for solution of the set of resulting ordinary differential equations and obtained results are compared with existing literature. The effect of active important physical parameters like Magnetic Field, Porosity parameter, Eckert number, Prandtl number and thermal radiation parameters on dimensionless velocity and energy fields are employed via graphs and tables. The velocity profile decreased by about 65% when the magnetic field parameter values increases from 0.5 to 1.5. On the other hand increased by 70% on energy profile. The energy profile enhanced by about 62% when the Radiation parameter values increases from 1.0 < Rd < 3.0. The current model may be applicable in real life practical implications of employing Engine oil-SWCNTs-MWCNTs-TiO2 nanofluids on cylinders encompass enhanced heat transfer efficiency, and extended component lifespan, energy savings, and environmental benefits. This kind of theoretical analysis may be used in daily life applications, such as engineering and automobile industries.

RESUMEN

Diabetes causes elevated blood sugar levels, and it has been categorized as one of the most frequent causes of death worldwide. This work aimed to analyze and compare the nutraceutical and therapeutic efficacy of fenugreek seeds (FSs) (Trigonella foenum-graecum) and black cumin seeds (BCSs) (Nigella sativa) against streptozotocin-induced diabetes mellitus in albino rats. FS and BCSs were evaluated for proximate analysis, phytochemicals, and antioxidant activities. Male albino rats were used to evaluate the in vivo antidiabetic activities of these medicinal plants for 42 days. Blood samples were drawn at regular intervals of 1 week to analyze blood glucose, plasma insulin, and cholesterol levels and to determine the homeostatic model assessment of insulin resistance (HOMA IR) index. At the end of the trial, pancreas tissue was also collected for histological examination. Results of the proximate analysis showed the significant presence of moisture, ash, fat, protein, and fiber. Antioxidant parameters like 2,2-diphenyl-1-picrylhydrazyl, total phenolic content, and total flavonoid content were found to be significant. There was a significant (p < 0.05) decrease in blood glucose level, serum cholesterol level, and insulin resistance in treatment groups T3-T5. Insulin and body weight results of treatment groups were significant (p < 0.05) compared to streptozotocin-intoxicated animals. Histological examination revealed the nutraceutical impact of selected herbal plants due to enhancing impact on the size and the number of ß-cells in the pancreas. Findings of current research work explore the antidiabetic capacity of selected nutraceutical and medicinal plants.

RESUMEN

Background: Globally, populations afflicted by armed conflict are known to have high rates of mental health disorders. Aims: This meta-analysis aims to estimate the prevalence of post-traumatic stress disorder (PTSD) and depressive symptoms among civilians residing in armed conflict-affected regions. Methods: This meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. A literature search employing MEDLINE(R), Embase Classic+Embase, APA PsycINFO, Ovid Healthstar, Journal@Ovid Full Text, Cochrane, PTSDpubs and CINAHL was conducted from inception until 19 March 2024 to identify relevant studies. Quality assessment was performed using the Joanna Briggs Institute Critical Appraisal Checklist for Prevalence Studies, and a Comprehensive Meta-Analysis was used to conduct the statistical analysis. Results: The search yielded 38 595 articles, of which 57 were considered eligible for inclusion. The included studies comprised data from 64 596 participants. We estimated a prevalence of 23.70% (95% CI 19.50% to 28.40%) for PTSD symptoms and 25.60% (95% CI 20.70% to 31.10%) for depressive features among war-afflicted civilians. The subgroup analysis based on time since the war and the country's economic status revealed the highest prevalence for both PTSD and depressive symptoms was present during the years of war and in low/middle-income countries. Conclusions: The results of this study provide conclusive evidence of the detrimental impacts of armed conflict on mental health outcomes. Hence, it is crucial to emphasise the significance of both physical and mental health in the aftermath of war and take appropriate humanistic measures to overcome challenges in the management of psychiatric illnesses. PROSPERO registration number: CRD42023416096.

RESUMEN

The study examined the antimicrobial and antioxidant potential of pure Acetyl-11-keto-ß-boswellic acid (AKBA), boswellic acid (70%) and AKBA loaded nanoparticles as topical polymeric films. The optimized concentration (0.05 % w/v) of pure AKBA, boswellic acid (BA), and AKBA loaded silver nanoparticles were used to study its impact on film characteristics. Carboxymethyl cellulose (CMC), sodium alginate (SA), and gelatin (Ge) composite films were prepared in this study. The polymeric films were evaluated for their biological (antioxidant and antimicrobial activities) and mechanical characteristics such as tensile strength (TS) and elongation (%). Moreover, other parameters including water barrier properties and color attributes of the film were also evaluated. Furthermore, assessments were conducted using analytical techniques like FTIR, XRD, and SEM. Surface analysis revealed that AgNP precipitation led to a few particles in the film structure. Overall, the results indicate a relatively consistent microstructure. Moreover, due to the addition of AKBA, BA, and AgNPs, a significant decrease in TS, moisture content, water solubility, and water vapor permeation was observed. The films transparency also showed a decreasing trend, and the color analysis revealed decreasing yellowness (b*) of the films. Importantly, a significant increase in antioxidant activity against DPPH free radicals and ABTS cations was observed in the CSG films. Additionally, the AgNP-AKBA loaded films displayed significant antifungal activity against C. albicans. Moreover, the molecular docking analysis revealed the inter-molecular interactions between the AKBA, AgNPs, and composite films. The docking results indicate good binding of AKBA and silver nanoparticles with gelatin and carboxymethyl cellulosemolecules. In conclusion, these polymeric films have potential as novel materials with significant antioxidant and antifungal activities.

RESUMEN

The present study incorporated an environment-friendly and cost-efficient green synthesis method for fabricating zinc oxide nanoparticles (ZnO-NPs) using various parts (leaves, buds, and flowers) of Bauhinia Variegate Linn. UV-Spectrophotometric analysis was used to confirm the synthesis of ZnO-NPs, which showed an absorption band within 360-380 nm range. Further techniques like FT-IR spectroscopy and (SEM) scanning electron microscopy equipped with a novel EDX were also included to confirm the synthesis, size, and shape of ZnO-NPs. Results obtained by FT-IR showed that the phytochemicals present in the ethanolic extract successfully acted as a capping agent. SEM micrographs confirmed irregularly shaped nanoparticles with an average size of 70-80 nm. The presence of Zinc and Oxygen peaks in EDX also confirmed the successful synthesis of ZnO nanoparticles. The radical scavenging (antioxidant) potential of prepared nanoparticles was also evaluated by DPPH radical assay. The ZnO-NPs obtained from the ethanolic extract of buds showed the highest %RSA (86%) as compared to the flowers (79%) and leaves (76%). The current study findings showed the versatile morphology of all parts of the plant with significant antioxidant potential, establishing the use of Bauhinia Variegate in biological systems for various biomedical applications. RESEARCH HIGHLIGHTS: A thorough comparative analysis of the radical scavenging power of major parts of the Bauhinia Variegate, which is 1st of its kind. Extensive characterization using UV-Vis spectrophotometry, FT-IR, SEM, and EDX to observe the conformational and morphological changes. Analysis of the reduction potential of leaves, buds, and flowers of a single plant for future directions in green synthesis.

RESUMEN

The preparation of ethylenediaminetetraacetic acid (EDTA) functionalized pine needles biochar (EDTA@BC) as a low-cost active adsorbent and its effectiveness in removing Ni(II) from aqueous solution at various conditions is reported in this paper. First, alkali activation was selected to render the pine needle biochar with an excellent porous structure and increased concentration of hydroxyl groups to facilitate grafting. Subsequently, a simple method was utilized to graft EDTA onto the biochar. The prepared EDTA@BC was characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and energy dispersive x-ray spectrometry (EDX). Batch adsorption studies were conducted to assess the impact of various parameters such as solution pH, adsorbent dosage, adsorbate volume, and shaking time on the removal efficiency of Ni(II). At pH 6, 100 mg dosage, 4 mL of adsorbate volume, and 10 min of shaking time, the maximum removal efficiency of Ni(II) was observed to be 89%. EDTA@BC showed reasonable sorption performance still after the third cycle of regeneration. The effect of interfering ions such as Pb, Cr, Cu, and Hg was evaluated, resulting a decrease of 69%, 78%, 76%, and 68%, respectively, in its sorption capacity. The Langmuir model provided a better fit for Ni(II) in the concentration range of 0.1-2000 ppm under optimized conditions, with qmax of 46.69 ± 1.031 mg/g and KL of 0.001, compared with the Freundlich isotherm, which yielded n = 0.234 and χ2 = 2.7899, Temkin isotherm (R2 = 0.9520), and Redlich-Peterson isotherm (R2 = 0.9725). The removal of Ni(II) by EDTA@BC was found to be the pseudo-second-order kinetics. Thermodynamic studies indicated adsorption process to be endothermic and nonspontaneous. Hence, a sustainable valorized bio-material (EDTA@BC) is prepared having better sorption efficiency of Ni(II) from aqueous solution with possible wide applicability. RESEARCH HIGHLIGHTS: New EDTA functionalized indigenous pine needles biochar (EDTA@BC) was prepared. This low-cost active adsorbent found effective in removing Ni(II) from aqueous solution. FTIR, SEM, and EDX proved synthesis and uptake of Ni(II) from aqueous solution. Ni(II) removal, regeneration, interfering and adsorption studies were performed by UV-Vis spectroscopy.

RESUMEN

INTRODUCTION: We systematically reviewed extant studies evaluating the efficacy and tolerability of xanomeline and xanomeline-trospium (KarXT) for treatment of adults with schizophrenia. METHODS: In accordance with PRISMA guidelines, articles were systematically searched for in databases and clinical trial registries. RESULTS: A total of 4 preclinical trials and 3 randomized controlled trials (RCTs) were included in this review. A 4-week RCT observed a difference of 24.0 points (SD 21.0) in the Positive and Negative Syndrome Scale (PANSS) total score between xanomeline and placebo groups (p = 0.039). A 5-week RCT observed PANSS total score changes from baseline to week 5, including -17.4 and -5.9 points in KarXT and placebo groups, respectively (LSMD -11.6 points; 95% CI -16.1 to -7.1; p < 0.001; d = 0.75). Another 5-week RCT observed PANSS total score changes from baseline to week 5, including -21.2 (SE 1.7) and -11.6 (SE 1.6) points in KarXT and placebo groups, respectively (LSMD -9.6; 95% CI -13.9 to -5.2; p < 0.0001; d = 0.61). Side effects include constipation, nausea, vomiting, dyspepsia, and dry mouth. CONCLUSION: KarXT offers an innovative non-D2 blocking approach, representing a promising treatment avenue for schizophrenia.

RESUMEN

BACKGROUND: Roux-en-Y gastric bypass (RYGB) has consistently demonstrated excellent weight loss and comorbidity resolution. However, outcomes vary based on patient's BMI. Single anastomosis duodeno-ileostomy with sleeve (SADI-S) is a novel procedure with promising short-term results. The long-term outcomes of SADI-S in patients with BMI ≥ 50 kg/m2 are not well described. We aim to compare the safety and efficacy of SADI-S with RYGB in this patient population. METHODS: We performed a multicenter retrospective study of patients with a BMI ≥ 50 kg/m2 who underwent RYGB or SADI-S between 2008 and 2023. Patient demographics, peri- and post-operative characteristics were collected. Complication rates were reported at 6, 12, 24, and 60 months postoperatively. A multivariate linear regression was used to evaluate and compare weight loss outcomes between both procedures. RESULTS: A total of 968 patients (343 RYGB and 625 SADI-S; 68.3% female, age 42.9 ± 12.1 years; BMI 57.3 ± 6.7 kg/m2) with a mean follow-up of 3.6 ± 3.6 years were included. Patients who underwent RYGB were older, more likely to be female, and have a higher rate of sleep apnea (p < 0.001), hypertension (p = 0.015), dyslipidemia (p < 0.001), and type 2 diabetes (p = 0.016) at baseline. The rate of bariatric surgery-specific complications was lower after SADI-S compared to RYGB. We reported no bariatric surgery related deaths after 1 year following both procedures. SADI-S demonstrated statistically higher and sustained weight loss at each time interval compared to RYGB (p < 0.001) even after controlling for multiple confounders. Lastly, the rate of surgical non-responders was lower in the SADI-S cohort. CONCLUSIONS: In our cohort, SADI-S was associated with higher and sustained weight-loss results compared to RYGB. Comorbidity resolution was also higher after SADI-S. Both procedures demonstrate a similar safety profile. Further studies are required to validate the long-term safety of SADI-S compared to other bariatric procedures.

RESUMEN

The trends in food packaging technologies are shifting toward utilizing natural and environmentally friendly materials prepared from biopolymers such as kappa carrageenan to replace synthetic polymers. In the current study, varying amounts (0.1, 0.2, and 0.3%) of grapefruit essential oil (GFO) were incorporated in kappa carrageenan-based edible films to improve their physicochemical properties. The developed film samples were characterized for their barrier, mechanical, morphological, optical, thermal, antioxidant, and biodegradable properties. The results obtained showed that the tensile strength of the carrageenan films enhanced significantly from 65.20 ± 4.71 to 98.21 ± 6.35 MPa with the incorporation of GFO in a concentration-dependent manner. FTIR and SEM analysis confirmed the intermolecular bonding between carrageenan and GFO, resulting in the formation of compact films. Incorporating GFO significantly enhanced the thermal resistance of oil-loaded films, as confirmed by TGA, DSC, and DTG analysis. The addition of GFO led to a substantial increase in the radical scavenging activity of the films, as evidenced by the DPPH and ABTS assays. Furthermore, the developed films were biodegradable in soil and seawater environments, indicating their potential as a sustainable alternative to traditional plastics. Findings demonstrated that GFO can be used as a natural antioxidant agent in kappa carrageenan-based films for potential applications in food packaging.

RESUMEN

Objective: This review summarizes evidence pertaining to the impact of the COVID-19 pandemic on the psychological health of children and adolescents with autism spectrum disorder (ASD). Materials and Methods: An electronic search was conducted using four major databases: PubMed, ScienceDirect, Web of Science, and Google Scholar. Using an umbrella methodology, the reference lists of relevant papers were reviewed, and citation searches were conducted. The study included articles written in English between January 2020 and March 2021 that focused on the psychological health of autistic children and adolescents. Results: All eight studies included in the final review were cross-sectional. Three of the eight studies were conducted in Italy, two in Turkey, and one study each in Portugal, Spain, and the United Kingdom, with a total of 1,407 participants. All studies used a mixture of standardized and non-standardized questionnaires to collect data. The total number of patients were 1407 at a mean age of 9.53 (SD = 2.96) years. Seven studies report gender; male 74.7% (657/880) and female 25.3% (223/880). The finding showed that behavioral issues in children and adolescents with ASD have significantly increased; 521 (51.9 percent) of the 1004 individuals with ASD presented with behavioral changes, including conduct problems, emotional problems, aggression, and hyperactivity. Some studies also found increased anxiety and difficulties managing emotions. Only one study reported clinical stabilization in children with ASD during COVID-19. Finally, 82.7% of families and caregivers of children with ASD (544 out of 658) faced challenges during COVID-19. Conclusion: Although the studies in this review suggest a general worsening of ASD children's clinical status, it remains difficult to draw definitive conclusions at this moment, with newer COVID-19 variants on the rise worldwide. During this difficult pandemic period, caregivers, families, and healthcare professionals are recommended to pay more attention to the ASD patients' health and care needs.

RESUMEN

This research focused on the development of films based on pectin and xanthan gum composite loaded with different concentrations of grapefruit essential oil (GFO). The fabricated films were characterized to assess the effect of GFO on the structural, mechanical, barrier, chemical, and antioxidant properties. The addition of GFO enhanced the functional properties of the films, as confirmed by FTIR analysis showing molecular interactions within the film matrix. SEM observations revealed that films with higher GFO content had a smoother, more compact structure with uniform oil distribution. Films loaded with oil demonstrated enhanced water resistance, as their decreased permeability ranged from 0.733 ± 0.009 to 0.561 ± 0.020 (g mm)/(m2.h.kPa). Additionally, these films showed a notable increase in tensile strength, ranging from 2.91 ± 0.19 to 8.55 ± 0.62 MPa. However, the addition of oil led to a reduction in the elongation at break of the films, which decreased from 52.84 ± 3.41 % to 12.68 ± 1.52 %, and a decline in transparency from 87.57 ± 0.65 % to 76.18 ± 1.12 %. Fabricated films exhibited enhanced antioxidant properties, as evidenced by increased DPPH• and ABTS•+ radical scavenging activities with the addition of GFO. The findings of the current study suggest that GFO is an effective natural additive for enhancing the physiochemical properties of pectin and xanthan gum-based films, making them more suitable for food packaging applications.

RESUMEN

Sodium tripolyphosphate (STPP), an inorganic and non-toxic polyphosphate, has potential applications as a crosslinking agent in the fabrication of edible films. This study utilized STPP in the development of sodium alginate-chitosan composite films, with a focus on their suitability for food packaging applications. The results indicate that the incorporation of STPP led to an increase in film thickness (from 0.048 ± 0.004 to 0.078 ± 0.008 mm), elongation at break (from 11.50 ± 1.49 % to 15.88 ± 2.14 %), water permeation (from 0.364 ± 0.010 to 0.521 ± 0.021 gmm/(m2h*kPa)), and moisture content (from 25.98 ± 0.20 % to 28.12 ± 0.17 %). In contrast, there was a decrease in tensile strength (from 30.23 ± 2.08 to 25.60 ± 1.22 MPa) and swelling index (from 752.9 ± 17.1 to 533.5 ± 8.9 %). Scanning electron microscopy (SEM) analysis revealed the formation of distinctive needle-like microcrystals with the incorporation of STPP. Fourier-transform infrared spectroscopy (FTIR) analysis indicated intermolecular interactions between STPP and the film-forming biopolymers. The data obtained from Thermogravimetric analysis (TGA) and Differential Scanning Calorimetry (DSC) demonstrated enhanced thermal stability of STPP-loaded films at elevated temperatures. Furthermore, the films exhibited increased DPPH scavenging activity with the addition of STPP. This study underscores the potential of STPP as a crosslinking agent for the development of composite edible films, suggesting applications in the field of food packaging.

RESUMEN

BACKGROUND: Obesity is a well-known risk factor for gastroesophageal reflux disease (GERD). Even though symptoms may be mitigated or resolved with the weight loss caused by sleeve gastrectomy (SG), it may be associated with higher incidences of postoperative GERD. Ligamentum teres cardiopexy (LTC) is an alternative to Roux-en-Y gastric bypass, the gold standard treatment for GERD. METHODS: This study was a retrospective single-center chart review, all patients in this cohort underwent LTC to treat refractory GERD at our institution. The option for LTC was presented after patients' refusal to undergo RYGB conversion. We collected baseline characteristics, standard demographics, pre-operative tests and imaging, and SG information, as well as intraoperative and perioperative data regarding LTC, and postoperative complications. RESULTS: Our cohort included 29 patients; most were Caucasian (44.8%) females (86.2%). The mean weight and BMI before LTC were 216.5 ± 39.3 lb and 36.1 ± 5.4 kg/m2, respectively. Mean total body-weight loss (TBWL) at 12 and 24 months were 28.7% ± 9.5% and 28.4% ± 12.4%, respectively. The mean interval between the index bariatric surgery and LTC was 59.9 ± 34.9 months, mean operative time was 67 ± 18.2 min, and median length of stay (LOS) was 1 day (IQR = 1-2 days). Twelve patients (57.1%) were able to discontinue antisecretory medications, while 9 (42.9%) still required them to remain asymptomatic. Mortality and reoperation rates were 0% and the incidence of complication was 19.4% (n = 6). CONCLUSIONS: LTC is a safe and effective surgical alternative to treat refractory GERD symptoms after SG.

RESUMEN

Plasticizers are employed to stabilize films by safeguarding their physical stability and avoiding the degradation of the loaded therapeutic drug during processing and storage. In the present study, the plasticizer effect (glycerol) was studied on bioadhesive films based on sodium alginate (SA), carboxymethyl cellulose (CMC) and gelatin (GE) polymers loaded with amphotericin B (AmB). The main objective of the current study was to assess the morphological, mechanical, thermal, optical, and barrier properties of the films as a function of glycerol (Gly) concentration (0.5-1.5 %) using different techniques such as Scanning Electron Microscope (SEM), Texture analyzer (TA), Differential Scanning Calorimeter (DSC), X-Ray Diffraction (XRD), and Fourier Transforms Infrared Spectroscopy (FTIR). The concentration increase of glycerol resulted in an increase in Water Vapor Permeability (WVP) (0.187-0.334), elongation at break (EAB) (0.88-35.48 %), thickness (0.032-0.065 mm) and moisture level (17.5-41.76 %) whereas opacity, tensile strength (TS) (16.81-0.86 MPa), and young's modulus (YM) (0.194-0.002 MPa) values decreased. Glycerol incorporation in the film-Forming solution decreased the brittleness and fragility of the films. Fourier Transform Infrared (FTIR) spectra showed that intermolecular hydrogen bonding occurred between glycerol and polymers in plasticized films compared to control films. Furthermore, molecular docking was applied to predict the binding interactions betweem AmB, CMC, gelatin, SA and glycerol, which further endorsed the stabilizing effects of glycerol in the complex formation between AmB, CMC, SA, and gelatin. The Findings of the current study demonstrated that this polymeric blend could be used to successfully prepare bioadhesive films with glycerol as a plasticizer.

The present study aimed to develop food packaging films by using a combination of pectin (PE) and sodium alginate (SA) enriched with Acetyl-11-keto-beta-boswellic acid (AKBA) as a functional or active ingredient. The fabricated films underwent comprehensive evaluation of their morphological, chemical, mechanical, barrier, optical, thermal, antioxidant, and antimicrobial properties. SEM and FTIR analysis showed that AKBA had good compatibility with film-forming components. The AKBA-loaded film samples exhibited a decrease in their barrier properties and tensile strength, but enhancements in both elongation at break and thickness values was observed. With the addition of AKBA, a significant increase (p < 0.05) in the ultraviolet barrier properties of the films and total colour variation (ΔE) was observed. TGA analysis of the films unveiled an improvement in thermal resistance with the incorporation of AKBA. Moreover, the films loaded with AKBA exhibited potent antioxidant activity in the ABTS and DPPH assay methods. Disk diffusion analysis showed the antimicrobial activity of AKBA-loaded films against P. aeruginosa, highlighting the potential of AKBA as a natural antimicrobial agent for the safety of food products. The results demonstrate the practical application of PE and SA active films loaded with AKBA, particularly within the food packaging industry.

RESUMEN

BACKGROUND: Malnutrition and liver impairment after duodenal switch (DS) are possible and undesired complications, often conservatively treated. However, in specific cases, surgical revision may be necessary. This study aims to describe outcomes achieved by two bariatric surgery centers and address effectiveness and safety of revisional surgical procedures to resolve these complications. METHODS: A retrospective chart review was performed in two bariatric surgery centers from 2008 to 2022. Patients who required revisional surgery to treat malnutrition and/or liver impairment refractory to nutritional and total parenteral nutrition intervention (TPN) after duodenal switch were included. No comparisons were performed due to the descriptive nature of this study. RESULTS: Thirteen patients underwent revisional surgery, the mean age was 44.7, the 53.8% were females, and the mean preoperative BMI was 54.7 kg/m2; the mean time between DS and revisional procedure was 26.5 months, and 69.1% of patients were placed on TPN. One patient developed hepatic encephalopathy; one patient presented with ascites, pleural effusion, and renal insufficiency, undergoing reoperation after revisional procedure due to a perforated ileal loop. Mortality rate was 0%; all patients regained weight after the revisional procedure, and the mean total protein and albumin blood levels 12 months after surgery were 6.3 and 3.6 g/dl, respectively. CONCLUSIONS: While refractory malnutrition and/or liver failure are rare among patients post-DS, if underdiagnosed and untreated, this can lead to irreversible outcomes and death. All revisional procedures included in this study resulted in improvement of the nutritional status and reversal of liver impairment, with low complication rates.

RESUMEN

In the current study, sodium caseinate and chitosan-based composite edible films were developed with the incorporation of black pepper (Piper nigrum) essential oil (BPO) in various concentrations (0.05, 0.1 and 0.15 %) for potential food packaging applications. The chemical composition of BPO was determined using GCMS and the major compound detected were ß-caryophyllene, limonene, ß-phellandren, pinene, copaene and α-humulene. The addition of BPO resulted in an increase in the thickness, EAB, WVP, moisture content and swelling index values of the films; however, the TS and water solubility decreased. The inclusion of BPO led to a substantial enhancement in the DPPH and ABTS radical scavenging capabilities of the edible films. SEM micrographs demonstrated intermolecular interaction between BPO, sodium caseinate, and chitosan. FTIR spectra confirmed the interaction of the functional groups of the polymers and BPO. The incorporation of the BPO increased the crystallinity of the films. Moreover, the thermal analysis including TGA, DSC and DTG demonstrated an increase in the thermal stability of the edible films with the addition of the BPO. These findings demonstrated that sodium caseinate and chitosan composite based edible films loaded with BPO can be used as sustainable active food packaging material.
