RESUMEN

BACKGROUND: Electroconvulsive therapy (ECT) and subanesthetic intravenous ketamine are both currently used for treatment-resistant major depression, but the comparative effectiveness of the two treatments remains uncertain. METHODS: We conducted an open-label, randomized, noninferiority trial involving patients referred to ECT clinics for treatment-resistant major depression. Patients with treatment-resistant major depression without psychosis were recruited and assigned in a 1:1 ratio to receive ketamine or ECT. During an initial 3-week treatment phase, patients received either ECT three times per week or ketamine (0.5 mg per kilogram of body weight over 40 minutes) twice per week. The primary outcome was a response to treatment (i.e., a decrease of ≥50% from baseline in the score on the 16-item Quick Inventory of Depressive Symptomatology-Self-Report; scores range from 0 to 27, with higher scores indicating greater depression). The noninferiority margin was -10 percentage points. Secondary outcomes included scores on memory tests and patient-reported quality of life. After the initial treatment phase, the patients who had a response were followed over a 6-month period. RESULTS: A total of 403 patients underwent randomization at five clinical sites; 200 patients were assigned to the ketamine group and 203 to the ECT group. After 38 patients had withdrawn before initiation of the assigned treatment, ketamine was administered to 195 patients and ECT to 170 patients. A total of 55.4% of the patients in the ketamine group and 41.2% of those in the ECT group had a response (difference, 14.2 percentage points; 95% confidence interval, 3.9 to 24.2; P<0.001 for the noninferiority of ketamine to ECT). ECT appeared to be associated with a decrease in memory recall after 3 weeks of treatment (mean [±SE] decrease in the T-score for delayed recall on the Hopkins Verbal Learning Test-Revised, -0.9±1.1 in the ketamine group vs. -9.7±1.2 in the ECT group; scores range from -300 to 200, with higher scores indicating better function) with gradual recovery during follow-up. Improvement in patient-reported quality-of-life was similar in the two trial groups. ECT was associated with musculoskeletal adverse effects, whereas ketamine was associated with dissociation. CONCLUSIONS: Ketamine was noninferior to ECT as therapy for treatment-resistant major depression without psychosis.

RESUMEN

BACKGROUND: Foot and mouth disease (FMD) is a highly contagious disease that impacts cloven-hoofed animals globally. The illegal trade of livestock between the border regions of Pakistan and Afghanistan can contribute to the spread of this disease. This study focuses on investigating the outbreaks of FMD that occurred in this area from June 2020 to May 2021. METHODS: RESULTS: A total of 233 epithelial tissue samples were collected, and 77% were found positive for FMDV through an antigen-detection by ELISA and molecular conformation through RT-PCR. The study found three serotypes of FMDV dominating in the border area of Pakistan with Afghanistan: O, A, and Asia-1. The outbreak activity was peaked between August/September followed by July/October 2020. Phylogenetic analysis conducted using the VP1 region sequence showed that serotype O isolates belonged to the Middle East-South Asia (ME-SA) topotype, PanAsia-2 lineage, and ANT-10 sub-lineage, while serotype Asia-1 isolates belonged to a novel lineage BD-18.The highest prevalence of serotype O of FMDV was found in cattle and buffalo of 1-2 year age group, while the highest outbreak ratio of serotype O was recorded in goats of 0-1 year age group and sheep of > 2 year age group. The serotype O was more prevalent in male than female sheep. The type A was more prevalent in females of sheep and goats than their corresponding males. The serotype Asia-1 was more prevalent in females of cattle and sheep than their corresponding males. The outbreak epidemiology of FMD varied significantly between various regions, months of study, animal species, age groups, and gender. CONCLUSIONS: The study found that FMD outbreaks in the border area of Pakistan and Afghanistan were diverse and complicated, and that different types of FMDV were circulating. The study recommended effective actions to stop FMD transmission in this area.

RESUMEN

Background: Covid-19 literacy, a social vaccine, is crucial to cope pandemic situations as it helps individuals to manage panic situations, adopt health preventive behaviours and adapting to the new normal. Objectives: This research examined the effects of Covid-19 literacy on fear, protective behaviour, and conspiracy beliefs of university students using an online questionnaire. Methods: A cross-sectional survey was conducted at two universities from Lahore with permission from concerned authorities. A total of 301 received responses were analyzed by applying descriptive as well as inferential statistics in SPSS. Results: The results indicated that Covid-19 literacy appeared to predict negatively fear of Covid-19 and conspiracy beliefs and positively health-protective behaviours. In other words, the university students with better Covid-19 literacy appeared to have less fear of Covid-19, more likely to adopt health-protective behaviours and believe less in conspirative information. Conclusions: These results demonstrated the potential benefits of Covid-19 literacy to respond proactively to the fear caused by the Covid-19 pandemic, managing infodemic and adoption of health-protective behaviours. These results would be useful for policymakers, NGOs, health professionals, and university librarians in planning health education and promotion for not only university students but also for general public. This research contributed to the existing research on health literacy related to the Covid-19 pandemic in general and Covid-19 literacy in particular as limited studies have been published so far.

RESUMEN

Despite a burgeoning older-adult population, the number of health-care professionals with geriatric expertise continues to lag behind. In 2014, the American Geriatrics Society's position statement encouraged interprofessional training for health-care professionals. Telementoring remotely connects clinicians with specialists for education and group mentoring. This dementia-focused, 11-month, 1-hour each, telementoring program was modeled on the Alzheimer's Association ECHO. Our interprofessional expert panel consisted of a geriatrician, a geriatric psychiatrist, an adult nurse practitioner (with geriatric expertise), two geriatric pharmacists, a licensed social worker (coordinating a dementia day program), and a project coordinator. Learners were residents in family medicine and general psychiatry, physician assistant residents in mental health and geriatric psychiatry fellows (total = 31). There was a significant improvement in learner intentions to change medication prescribing by midpoint assessment (p = 0.04). Learners reported few barriers to incorporating skills they learned. An interprofessional telementoring program can help nongeriatric practitioners improve skills in caring for older adults.

RESUMEN

BACKGROUND: Management of diabetes during fasting is a clinical challenge. Sodium glucose co-transporter -2 inhibitors (SGLT2i) are considered safe with a low risk of hypoglycemia. However, studies on SGLT2i are scarce. This study was designed to compare the efficacy, safety, and tolerability of empagliflozin with metformin during Ramadan in comparison with sitagliptin and metformin. METHODS: It was a prospective, observational study, conducted at 11 different sites all across Pakistan on an outpatient basis during Ramadan (May 2021-June 2021). including 132 patients, 88 who received metformin and sitagliptin, and 44 patients who received metformin and empagliflozin. RESULTS: Patients of the SGLT-2i group experienced similar symptomatic hypoglycemic episodes (15.9%) as the sitagliptin group. There was an improvement in blood sugar levels after the use of SGLT-2i (RBS 181 ± 64 before Ramadan vs 162 ± 53 after Ramadan). HbA1c also improved after the use of SGLT-2i before and after Ramadan (7.2 ± 0.8 vs 6.9 ± 0.9 for Metformin + Empagliflozin and 7.8 ± 1.5 vs 7.6 ± 1.6 for Metformin and sitagliptin). Weight and BMI improved after the use of SGLT-2i (BMI 36.5 ± 4.8 before Ramadan and 33.7 ± 2.4 after Ramadan). There were no reported cases of urinary tract infection in the empagliflozin group. CONCLUSION: SGLT-2 inhibitors combined with metformin for patients with diabetes during Ramadan fasting is as effective, safe and well tolerated as DPP4 combined with metformin.

RESUMEN

BACKGROUND: Sodium-Glucose-Co-Transporter 2 (SGLT2) inhibitor (Empagliflozin) is an effective drug in controlling blood glucose through predominantly glycosuria. Glycosuria increases the risk of genitourinary infections in diabetes. This study was aimed to establish the safety and efficacy of Empagliflozin (Group-A) versus standard care (Group-B) in Pakistani Muslim individuals with type 2 diabetes. METHODS: A multicenter, randomized clinical trial was conducted in five cities across Pakistan from July 2019 to August 2020. Patients of both genders aged 18-75 years, body mass index (BMI) ≤ 45 kg/m2, glycosylated hemoglobin (HbA1c) 7-10% (53 mmol/mol to 86 mmol/mol) and treatment-naive to Empagliflozin were included. Treatment was given for 24 weeks, and allocation was done through randomization. RESULTS: Out of 745 screened patients, 333 met the eligibility criteria, and a total of 244 (73.3%) patients were enrolled. More hypoglycemic events were reported in the standard care group, whereas positive urine culture, fungal infection, dehydration, and hypotension occurrence were comparable between the two groups. The 6 months mean HbA1c reduction was significant in both groups; (Group-A: 0.91 ± 0.15; p < 0.001 vs. Group-B2: 0.79 ± 0.14; p < 0.001). Efficacy comparison at 6 months revealed a significant reduction in weight and systolic blood pressure (SBP) in Group A only (Group-A: 1.4 ± 0.4 kg; p < 0.002 vs. Group-B: 0.01 ± 0.5 kg; p < 1.00), (Group-A: 5.1 ± 1.7 mmHg; p < 0.012 vs. Group-B: 2.3 ± 1.7 mmHg; p < 0.526). CONCLUSIONS: Empagliflozin was a safe drug compared to standard care in Pakistani Muslim patients with diabetes. It was as effective as standard care in the clinical setting but achieved glycemic control by reducing weight and SBP in type 2 diabetes patients. TRIAL REGISTRATION: This study was registered in the NIH US National Library of Medicine clinical trials registry at Clinicaltrials.gov with the registration number: NCT04665284 on 11/12/2020.

RESUMEN

Genes are composed of DNA and each gene has a specific sequence. Recombination or replication within the gene base ends in a permanent change in the nucleotide collection in a DNA called mutation and some mutations can lead to cancer. Breast adenocarcinoma starts in secretary cells. Breast adenocarcinoma is the most common of all cancers that occur in women. According to a survey within the United States of America, there are more than 282,000 breast adenocarcinoma patients registered each 12 months, and most of them are women. Recognition of cancer in its early stages saves many lives. A proposed framework is developed for the early detection of breast adenocarcinoma using an ensemble learning technique with multiple deep learning algorithms, specifically: Long Short-Term Memory (LSTM), Gated Recurrent Units (GRU), and Bi-directional LSTM. There are 99 types of driver genes involved in breast adenocarcinoma. This study uses a dataset of 4127 samples including men and women taken from more than 12 cohorts of cancer detection institutes. The dataset encompasses a total of 6170 mutations that occur in 99 genes. On these gene sequences, different algorithms are applied for feature extraction. Three types of testing techniques including independent set testing, self-consistency testing, and a 10-fold cross-validation test is applied to validate and test the learning approaches. Subsequently, multiple deep learning approaches such as LSTM, GRU, and bi-directional LSTM algorithms are applied. Several evaluation metrics are enumerated for the validation of results including accuracy, sensitivity, specificity, Mathew's correlation coefficient, area under the curve, training loss, precision, recall, F1 score, and Cohen's kappa while the values obtained are 99.57, 99.50, 99.63, 0.99, 1.0, 0.2027, 99.57, 99.57, 99.57, and 99.14 respectively.

RESUMEN

OBJECTIVE: Patient microaggressions affect practitioners in all fields of healthcare and especially psychiatry. In multiple studies, healthcare professionals reported high rates of patient microaggressions and discrimination. To date, this is the first scoping review of recommendations and trainings on patient microaggressions. METHOD: A scoping review of articles indexed in PubMed, PsycINFO, Medline, ERIC, and MedEdPORTAL was conducted from July 2020 to August 2020 to identify recommendations and solutions for healthcare professionals on responding to patient microaggressions. RESULTS: The review identified 27 studies that provide recommendations and trainings for healthcare professionals to address patient microaggressions. Twenty studies outlined recommendations for healthcare professionals and systems on how to respond to patient offenses. These 20 studies were grouped into establishing a supportive culture, addressing the microaggression, supporting the targets of microaggressions, discriminatory requests, and institutional responses. Six articles described trainings that equip providers with tools to address patient microaggressions, including the ERASE framework ("Expect/Recognize/Address/Support/Establish, Encourage"); Stop, Talk, and Roll; interrupting microaggressions; XYZ ("I felt X when Y because Z"); the ACTION model ("Ask/Come/Tell/Impact/Own/Next"); and the OWTFD tool ("Observe/Why/Think/Feel/Desire"). CONCLUSION: Recommendations and trainings for the response to microaggressions are emerging, and results of trainings are encouraging. However, more work is needed to evaluate the effectiveness of these trainings in clinical settings and longitudinally.

RESUMEN

OBJECTIVE: To compare the effect of intra-cuff lidocaine versus alkalinized lidocaine in the prevention of post-operative sore throat. Methods: The cross-sectional study was conducted from June 15 to July 15, 2019, at the Department of Anaesthesiology, Liaquat National Hospital and Medical College, Karachi, and comprised patients of either gender aged 15-50 years classified as American Society of Anaesthesiologist class 1-2 and undergoing general anaesthesia with endotracheal intubation expected to last more than one hour. The patients were randomised into Group L and Group LA. General anaesthesia was given using induction dose of propofol 2-3mg/kg, nalbuphine 0.1mg/kg and atracurium 0.5mg/kg and female patients were intubated with 7.0mm size endotracheal tube and males patients with 8.0mm. All intubations were performed by an anaesthesiologist with minimum of two-year experience. The endotracheal tube cuff was inflated by using plain lidocaine 2% in group L and 2% lidocaine with 8.4% sodium bicarbonate in LA group till the air leak diminished. Post-surgery, the patients were assessed on extubation for any emergence phenomenon and were re-assessed at 1st, 6th, 12th and 24th hour. The assessment was done by the on-call anaesthesiology resident who was blinded to the study group. Data was collected using a proforma. The analysis was done using software IBM SPSS Statistics 23.0. Chi-Square Test was applied to analyse the data. RESULTS: Of the 58 patients, 33(56.9%) were male and 25(43.1%) were female. There were 26(44.8%) patients aged 25-36 years, while 12(20.7%) each were aged 36-45 years and 46-55 years. There were 29(50%) patients in each of the 2 groups. After 24 hours, 44(75.9%) patients in Group L did not complain of any pain, while in group LA the corresponding number was 56(96.6%). Both in terms of cough and hoarseness at 24 hours, 56(96.6%) patients in Group L did not have complaints, while in Group LA there were no such complaints. In Group L, heart rate 60-80 was noted in 20(69%) patients and 81-100 in 9(31%). In Group LA, the corresponding values were 17(58.6%) and 12(41.4%). Conclusion: Alkalinized lidocaine was found to be highly effective in preventing post-operative throat complications compared to lidocaine.

RESUMEN

BACKGROUND: One of the leading long-term complications of type 2 diabetes mellitus (T2DM) includes renal dysfunction and urinary tract infections (UTI) which are considered to be prevalent in uncontrolled diabetes. Moreover, physiological factors like age, gender, duration of diabetes, other diabetic complications like neuropathy, autonomic neuropathy and glycosuria are also considered as predisposing factors for increased prevalence of UTI in diabetes which can be symptomatic or asymptomatic. METHODS: This was a cross-sectional, multi-centre study including diabetic patients from 12 clinical sites spread across major cities of Pakistan. The inclusion criteria were adult Pakistani population of age between 18 to 75 years both genders and suffering from T2DM irrespective of duration. A detailed clinical history of the past 3 months was recorded and, biochemical investigations of blood samples were conducted. Urine culture analysis performed identified the type of pathogen present and was done only for asymptomatic patients. RESULTS: A total of 745 type 2 diabetic patients were initially screened, out of 545 patients considered for final analysis 501 (91.92%) were negative and the rest 44 (8.08%) had positive urine culture. Female gender had a significantly higher proportion of positive urine culture (77.27%, p-value< 0.001). Body mass index and mean age had insignificant distribution among the two groups of positive and negative urine culture, with age 40-59 years having higher proportion (70.45%) in the positive group. Escherichia coli was detected in most of the positive samples (52.3%). All bacterial samples were found resistant to Ciprofloxacin. CONCLUSION: Diabetic Pakistani muslim female patients are identified to be at high risk of suffering from asymptomatic UTI and age more than 40 years is an important risk factor. Escherichia coli was the most common causative organism among people living in this geographical area.

RESUMEN

Deoxynivalenol (DON) is considered to be a grave threat to humans and animals. Ginsenoside Rb1 (Rb1) has been reported for its antioxidant potential and medicinal properties. However, the shielding effects of Rb1 and the precise molecular mechanisms against DON-induced immunotoxicity in mice have not been reported yet. In the present research, 4-weeks old healthy C57BL/6 mice were randomly assigned into four experimental groups (n = 12), viz., CON, DON 3 mg/kg BW, Rb1 50 mg/kg BW and DON 3 mg/kg + Rb1 50 mg/kg BW (DON + Rb1). Feed intake and body weight gain were monitored during the entire experiment (15 d). Our results demonstrated that Rb1 markedly increased the ADG (30%) and ADFI (25.10%) of mice compared with DON group. Furthermore, Rb1 alleviated the DON-induced immune injury by relieving the splenic histopathological alteration, enhancing the T-lymphocytes subsets (CD4+, CD8+), the levels of cytokines (IL-2, IL-6, IFN-γ, and TNF-α), as well as production of immunoglobulins (IgA, IgM, and IgG). Moreover, Rb1 ameliorated DON-inflicted oxidative stress by reducing the ROS, MDA and H2O2 contents and boosting the antioxidant defense system (T-AOC, T-SOD, CAT, and GSH-Px). Additionally, Rb1 significantly reversed the DON-induced excessive splenic apoptosis via modulating the mitochondria-mediated apoptosis pathway in mice, depicting the decreased percentage of splenocyte apoptotic cells by 26.65%, down-regulated the mRNA abundance of Bax, caspase-3, caspase-9, and protein expression of Bax, cleaved caspase-3, and Cyt-c. Simultaneously, Rb1 markedly rescued both Bcl-2 mRNA and protein expression levels. Taken together, Rb1 mitigates DON-induced immune injury by suppressing the oxidative damage and regulating the mitochondria-mediated apoptosis pathway in mice. Conclusively, our current research provides an insight into the preventive mechanism of Rb1 against DON-induced immune injury in mice and thus, presents a scientific baseline for the therapeutic application of Rb1.

RESUMEN

This study aimed to investigate the chemical composition, using GC-MS, and anti-biofilm potential of black cardamom essential oil (BCEO) against biofilms of Escherichia coli O157:H7 and Salmonella Typhimurium JSG 1748 through inhibition of bacterial quorum sensing. GC-MS quantification demonstrated that BCEO contains 1,8-cineole (44.24%), α-terpinyl acetate (12.25%), nerolidol (6.03%), and sabinene (5.96%) as the major bioactive compounds. Antioxidant assays for BCEO revealed the total phenolic and flavonoid mean values were 1325.03 ± 7.69 mg GAE 100/g and 168.25 ± 5.26 mg CE/g, respectively. In regards to antimicrobial potential, Candida albicans was the most sensitive species compared to Streptococcus mutans, Staphylococcus aureus, Listeria monocytogenes, Bacillus cereus, and Salmonella Typhimurium with the following zones of inhibition; 14.4 ± 0.52, 13.2 ± 0.42, 11.2 ± 0.28, 11.0 ± 0.52, 8.2 ± 0.24 and 6.6 ± 0.18 mm in diameter, respectively. Biofilm inhibition by BCEO was concentration-dependent, when various concentrations of 0.03, 0.06, 0.12, 0.25 and 0.5% were applied, 33.67, 34.14, 38.66, 46.65 and 50.17% of Salmonella Typhimurium biofilm was inhibited, while 47.31, 54.15, 76.57, 83.36 and 84.63% of Escherichia coli biofilm formation was prevented. Chromobacterium violaceum ATCC 12,472 and its product violacein, was used as a microbial indicator for enhancement or inhibition of quorum sensing. Our data showed that 0.5% of BCEO inhibited violacein production without influencing the growth of Chromobacterium violaceum, while 1% of BCEO, caused 100% inhibtion of violacein production together with 30% inhibition of growth. This study shows that BCEO possesses promising antioxidant and antimicrobial potential, and found anti-biofilm activities linked to the quenching of the quorum sensing system of E. coli and S. Typhimurium.

RESUMEN

OBJECTIVE: The goal of this study was to explore how prepared psychiatry programs are to teach residents to practice resource management and high-value, cost-effective care. METHODS: An anonymous online survey was sent to 187 psychiatry training directors between July and September 2015. RESULTS: Forty-four percent of training directors responded to the survey. While most training directors who responded (88%) agreed that that graduate medical education has a responsibility to respond to the rising cost of health care, fewer than half agreed that that their faculty members consistently model cost-effective care (48%), that residents have access to information regarding the cost of tests and procedures (32%), and that residents are prepared to integrate the cost of care with available evidence when making medical decisions (44%). Only 11% reported providing training in resource management. Barriers cited to teaching cost-effective care included a lack of information regarding health care costs (45%), a lack of time (24%), a lack of faculty with relevant skills (19%), and competing training demands and priorities (18%). Training directors also noted a lack of available curricular resources and assessment tools (21%). Another 12% cited concerns about cost containment overriding treatment guidelines. Ninety percent of training directors agreed that they would be interested in resources to help teach high-value, cost-effective care. CONCLUSIONS: Most psychiatry programs do not provide formal training in resource management but are interested in resources to teach high-value, cost-effective care. Curricula for residents and faculty may help meet this need.

RESUMEN

The present study investigated the status of peste des petits ruminants (PPR) for the first time in the camels of Pakistan. The samples were collected from the camel residing area of Sindh, Pakistan, and analyzed for breeds (Dhatti and Larri), districts (Tharparkar and Umerkot), age (young, adult, and old), and sexes (male and female). The sera samples (n = 200) were analyzed for the detection of antibodies using a competitive enzyme-linked immunosorbent assay (cELISA). Moreover, the nasal and fecal samples were screened for the PPR virus. Finally, the positive nasal and fecal samples were validated using reverse transcriptase-polymerase chain reaction (RT-PCR) and immunocapture enzyme-linked immunosorbent assay (Ic-ELISA). The cELISA results showed an overall prevalence of 8.5% PPR in the study area. The camels of Tharparkar (10.9%; 95% confidence interval (CI) 9.2-12.9) showed higher seroprevalence of PPR antibodies than those of Umerkot (5.5%; 95% CI 4.1-7.2). Moreover, the Larri breed exhibited slightly greater resistance against the disease, because the camels of Dhatti breed (9.0%; 95% CI 7.5-11.0) exhibited a numerically higher (p > 0.05) seroprevalence of PPR in comparison with those of Larri breed (7.9%; 95% CI 6.4-9.9). Furthermore, the young and old camels were more susceptible to the disease attack, because the adults (6.3%; 95% CI 5.0-7.8) exhibited significantly (p < 0.05) lower prevalence rate than the young (9.2%; 95% CI 7.6-11.1) and old (10.3%; 95% CI 8.9-11.9) camels. Finally, the results of the Ic-ELISA and HA test established the 8.3 and 8.2% prevalence of PPR antigen in nasal and fecal material samples, respectively, while the RT-PCR results validated the seropositive animals. These findings confirmed that the prevalence of PPRV infection in the camels of the Sindh province of Pakistan hence urged the need to take effective measures for prevention and control of the disease.

RESUMEN

Checking responsiveness is the mainstay in cardiopulmonary resuscitation (CPR). It is rare in the clinical situation when the patient requires resuscitation despite the presence of wakefulness. We report a case in which the patient presented with flat arterial line and absence carotid pulse while he was awake. A thorough literature review will also be discussed.

RESUMEN

Mailed outreach promoting colorectal cancer (CRC) screening with a stool blood test kit may increase participation, but magnitude and consistency of benefit of this intervention strategy is uncertain. Our aim was to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing mailed outreach offering stool tests to usual care, clinic-based screening offers on CRC screening uptake in the USA. We performed a systematic literature search of five databases for RCTs of mailed outreach from January 1980 through June 2017. Primary outcome was screening completion, summarized using random-effects meta-analysis as pooled differences in proportion completing the screening and relative risk of achieving screening compared to control. Subgroup analyses by test type offered-fecal immunochemical test (FIT) or guaiac fecal occult blood test (gFOBT), the presence of telephone reminders, and the presence of predominant underserved/minority population within study were performed. Quality of evidence was evaluated using the GRADE framework. Seven RCTs which enrolled 12,501 subjects were included (n = 5703 assigned mailed outreach and n = 6798 usual care). Mailed outreach resulted in a 28% absolute (95% CI 25-30%; I2 = 47%) and a 2.8-fold relative (RR 2.65, 95% CI 2.03-3.45; I2 = 92%) increase in screening completion compared to usual care, with a number needed to invite estimated to be 3.6. Similar outcomes were observed across subgroups. Overall body of evidence was at moderate quality. Mailed outreach offering a gFOBT or FIT is associated with a large and consistent increase in CRC screening completion and should be considered for more widespread implementation for improving screening rates nationwide.

RESUMEN

Heat stress causes significant economic losses in poultry production, especially in tropical and arid regions of the world. Several studies have investigated the effects of heat stress on the welfare and productivity of poultry. The harmful impacts of heat stress on different poultry types include decreased growth rates, appetites, feed utilization and laying and impaired meat and egg qualities. Recent studies have focused on the deleterious influences of heat stress on bird behaviour, welfare and reproduction. The primary strategies for mitigating heat stress in poultry farms have included feed supplements and management, but the results have not been consistent. This review article discusses the physiological effects of heat stress on poultry health and production and various management and nutritional approaches to cope with it.

RESUMEN

BACKGROUND: Osmotic pretreatment is an effective processing unit for improving the textural quality of dried fruit and vegetable snacks, whereas nutrition loss and high calorie after impregnation is still a noteworthy shortcoming of sugar-immersed products. Therefore, the use of apple juice concentrate as a clean label solution to improve the qualities of instant controlled pressure drop (DIC)-dried carrot chips was investigated. RESULTS: Apple juice concentrate impregnation substantially enhanced the physical properties of the carrot chips, including hardness (38.28 N), crispness (2.01 mm), porosity (66.72%) and homogeneous microstructure, comparable to chips obtained using sucrose and maltiltol based osmotic solutions. Additionally, compared to the sucrose and maltiltol impregnated chips, a higher retention of carotenoids (302.81 µg g-1 , dry basis), a higher multiplicity of phenolic compounds, stronger antioxidant activities and a superior sensory score were observed in the chips pretreated with apple juice concentrate. CONCLUSION: Apple juice concentrate could be used as a clean label osmotic solution to enhance the organoleptic attributes and fortify the nutritional properties of DIC-dried carrot snacks. © 2019 Society of Chemical Industry.
