Seed biopriming with Ochrobactrum ciceri mediated defense responses in Zea mays (L.) against Fusarium rot.

Seed bio-priming is a simple and friendly technique to improve stress resilience against fungal diseases in plants. An integrated approach of maize seeds biopriming with Ochrobactrum ciceri was applied in Zn-amended soil to observe the response against Fusarium rot disease of Zea mays (L.) caused by Fusarium verticillioides. Initially, the pathogen isolated from the infected corn was identified as F. verticillioides based on morphology and sequences of the internally transcribed spacer region of the ribosomal RNA gene. Re-inoculation of maize seed with the isolated pathogen confirmed the pathogenicity of the fungus on the maize seeds. In vitro, the inhibitory potential of O. ciceri assessed on Zn-amended/un-amended growth medium revealed that antifungal potential of O. ciceri significantly improved in the Zn-amended medium, leading to 88% inhibition in fungal growth. Further assays with different concentrations (25, 50, and 75%) of cell pellet and the cultural filtrate of O. ciceri (with/without the Zn-amendment) showed a dose-dependent inhibitory effect on mycelial growth of the pathogen that also led to discoloration, fragmentation, and complete disintegration of the fungus hyphae and spores at 75% dose. In planta, biopriming of maize seeds with O. ciceri significantly managed disease, improved the growth and biochemical attributes (up to two-fold), and accelerated accumulation of lignin, polyphenols, and starch, especially in the presence of basal Zn. The results indicated that bioprimed seeds along with Zn as the most promising treatment for managing disease and improving plant growth traits through the enhanced accumulation of lignin, polyphenols, and starch, respectively.

Dysphagia and obstructive sleep apnoea in post-extubated intensive care unit patients.

OBJECTIVE: To determine the relationship between dysphagia and obstructive sleep apnoea and its association with age, gender and Glasgow Coma Scale in post-extubated patients in an intensive care setting. METHODS: The correlational study was conducted from July 1 to October 31, 2021, at the intensive care unit of Evercare Hospital, Lahore, Pakistan, and comprised post-extubated patients of either ender aged 45-70 years within 72 hours following extubation and having Glasgow comma scale score 11-15. Gugging Swallowing Screen and Obstructive Sleep Apnoea questionnaires were used for data collection. Data was analysed using SPSS 25. RESULTS: Of the 29 patients with a mean age of 57.45±8.74 years, 18(62.1%) were males. There was a significant correlation between dysphagia and obstructive sleep apnoea (p=0.005). The Obstructive Sleep apnoea score had a significant negative correlation with Glasgow Coma Scale score (p=0.01), while dysphagia revealed a significant positive correlation (p<0.001) with Glasgow Coma Scale score. Age and gender had no significant association with either dysphagia or obstructive sleep apnoea (p>0.05). CONCLUSIONS: There was a significant correlation between dysphagia and obstructive sleep apnoea in post-extubated patients under intensive care. Both dysphagia and obstructive sleep apnoea had a significant correlation with Glasgow Coma Scale score.

Air Leak Syndrome In Patients With Severe Covid Pneumonia.

Abstract: There are number of emerging studies that link the air leak syndrome (ALS) with COVID 19 disease but still data to explain the association, incidence and outcome in these patients is lacking. We aim to understand the risk factors and clinical outcome of these air leakage events in COVID 19 patients admitted to our institution. Methods: This is a single-centered case series conducted at the COVID unit of the SMBBIT in Karachi, Pakistan. Data collection was done from April 24, 2020 to June 10, 2021. Results: There were 19 patients with severe COVID pneumonia who developed air leaks. Most common finding was subcutaneous emphysema 94%. Four patients (21%) didn't receive positive pressure ventilation in any form. Median time of developing air leak from admission is 5 [2-9] and from PPV is 2 [1-3] days. There was high percentage of mortality 84.5 % in these patients.

A Comparison Between the Postoperative Complications of Laparoscopic Sleeve Gastrectomy (LSG) and Laparoscopic Roux-en-Y Gastric Bypass (RNYGB) in Patients With Morbid Obesity: A Meta-Analysis.

The most successful method for treating obesity is bariatric surgery. The two most common surgeries for treating morbid obesity are the laparoscopic Roux-en-Y gastric bypass (RNYGB) and the laparoscopic sleeve gastrectomy (LSG). However, there has not been a thorough analysis of the differences in their adverse effects. The aim of this study was to analyze if RNYGB and LSG had comparable postoperative complications and mortality. To that end, results from trials comparing those who underwent RNYGB and those who underwent LSG were combined. We explored the Cochrane Library, PubMed, EMBASE, and Web of Science databases for collecting pertinent data, and 10 RCTs were included in the study. Standard deviations were used to determine the risk ratio (RR) and the 95% confidence interval (CI). No substantial difference in mortality was observed between the two procedures. However, our pooled analysis showed that patients who underwent RNYGB needed some reoperation at a higher rate compared to those who had LSG, with a pooled RR of 0.64 (95% CI: 0.42-0.98; p=0.04). Patients who had LSG suffered from fewer postoperative sequelae. While the risk of other complications was higher in RNYGB, our analysis showed that the frequency of gastroesophageal reflux disease (GERD) after LSG was greater than after RNYGB, with a pooled RR of 4.00 (95% CI: 2.55-6.28; p<0.001). Based on the above-mentioned findings, RNYGB and LSG had comparable mortality rates; however, patients who underwent LSG had a reduced risk of complications and reoperations after surgery compared to those who had RNYGB.

ENSEAL® Hemorrhoidectomy, a Novel Technique, Versus Conventional Open Method for the Management of Grade III and IV Hemorrhoids.

Background Surgical removal of hemorrhoids is the gold-standard treatment for symptomatic grade III and IV hemorrhoid disease. There are numerous ways the hemorrhoidectomy surgical procedure is done but the most effective and least painful way is still to be elucidated. Objective To compare the outcomes of ENSEAL® (Ethicon, Inc., Raritan, USA) versus gold standard Milligan-Morgan hemorrhoidectomy in patients presenting with grade-III and IV hemorrhoids Materials and methods After ethical approval, the Randomized Controlled Trial was conducted at the Department of Surgery, Unit III, Lahore General Hospital, Lahore, Pakistan, between January 2020 and January 2022. In this study, 140 patients who met the inclusion criteria were recruited after informed consent. Patients were split randomly into two equal groups using a lottery technique. In group A, hemorrhoidectomy was carried out with ENSEAL®, whereas in group B, open hemorrhoidectomy was performed by the Milligan-Morgan method. the surgery duration and blood loss were noted. After the operation, patients were transferred to and discharged from the post-anesthesia recovery room. Patients were further followed up for pain scores after 24 hours. Data was analyzed by using Statistical Package for Social Sciences (SPSS) v25 (IBM Corp., Armonk, USA). Data was categorized for age, gender, body mass index (BMI), degree of hemorrhoids, and duration of hemorrhoids. A p-value <0.05 was considered significant. Results 140 patients were included in this study. Group A patients underwent ENSEAL® hemorrhoidectomy, and group B was formed from those who underwent the Milligan-Morgan procedure. In group A, there were 41 (58.5%) males and 29 (41.4%) females, while in group B, there were 43 (61.4%) males and 27 (38.5%) females. The mean age of group A patients was 49.97 ± 7.36 years and 43.2 ± 8.01 years in group B. In group A, the mean operative time was 20.87 ± 3.05 min, while 27.10 ± 3.42 min in group B, which is statistically significant with a p-value of <0.001. In group A, mean blood loss was 9.79 ± 2.87 ml, while 13.36 ± 3.73 ml in group B, which is statistically significant with a p-value of <0.001. In group A, the mean pain score was 2.7 ± 1.08, while 3.34 ± 1.16 in group B, which is statistically significant with a p-value of <0.001. Conclusion When considering the length of the procedure and blood loss, ENSEAL® hemorrhoidectomy has been determined to be an effective treatment that the patients tolerated well. Therefore, ENSEAL® hemorrhoidectomy can be a safe and efficient alternative to conventional treatment for hemorrhoids that are causing symptoms.

Comparative Efficacy of Topical Metronidazole and Glyceryl Trinitrate Versus Topical Glyceryl Trinitrate Alone in the Treatment of Acute Anal Fissure: A Randomized Clinical Trial.

Background and objective An anal fissure is a longitudinal, oval lesion in the anal canal. In over 90% of instances, the anal fissures are located posterior to the midline and produce discomfort upon defecation and/or bleeding owing to spasms of the internal anal sphincter that leads to ischemia. This research aimed to determine if topical metronidazole treatment when combined with glyceryl trinitrate 0.2% (GTN), is more successful than GTN alone in reducing the time for an acute anal fissure to heal. Material and methods This study was a single-blinded, randomized controlled trial conducted at the DHQ Hospital Okara from January 2022 to August 2022. Patients of both genders, aged 18 to 70 years, with acute anal fissures, were included. One hundred forty patients who satisfied the inclusion criteria were randomized through the lottery technique and were divided into two groups (70 in each group). Group A contained patients who got metronidazole combination with GTN, while in Group B, patients treated with GTN alone without metronidazole. The primary endpoint was fissure healing, confirmed as finding a scar where the fissure was. While the secondary endpoint was maximum pain on defecation assessed by the Visual Analogue Scale (VAS). Statistical analysis was performed using Statistical Package for Social Sciences (SPSS) v24. Chi-Square and Fisher's Exact tests were done for statistical analysis, and p < 0.05 was considered significant. Results Three patients lost the follow-up. Out of the remaining 137, 70 (51.1%) patients were male. The patient's ages ranged from 22 to 68 years, with a mean age of 39.18 ± 11.52. One hundred twenty six (92%) complained of pain on defecation with a mean VAS of 6.01 ± 2.35. 80 (58.4%) patients complained of perianal itching, while 25 (18.2%) patients complained of bleeding on defecation. On week 1 follow-up, in group A out of 69 patients, 27 (39.1%) had complete healing, 38 (55.1%) had partial healing, while in group B out of 68 patients, one (1.4%) had complete healing, 43 (63.2%) had partial healing (p = < 0.001, significant).  On week 3 follow-up, in group A out of 69 patients, 47 (68.1%) had complete healing, and 22 (31.8%) had partial healing, while in group B out of 68 patients, 16 (23.5%) had complete healing, 49 (72%) had partial healing (p = < 0.001, significant). Mean VAS score of group A was 0.61 ± 1.38 while that of group B was 2.57 ± 2.50 (p = < 0.001, significant). Conclusion Using topical metronidazole as an addition to standard therapy may reduce the chronicity of acute anal fissures and prevent surgical treatments with high rates of complications.

Content of Serious Illness Care conversation documentation is associated with goals of care orders-a quantitative evaluation in hospital.

BACKGROUND: The Serious Illness Care Program (SICP) increases quality of documentation about patients' values and priorities, but it is not known whether patient characteristics and goals of care are associated with the elements documented. The purpose of this study was to explore for associations between the quantity and type of elements documented after SICP conversations with patient characteristics and goals of care order. METHODS: Documentation of SICP conversations by internal medicine physicians with hospitalized patients was evaluated in a retrospective chart review between March 2018 to December 2019. The conversations occurred after SICP implementation in a Tertiary Hospital, Medical teaching unit which uses "Goals of Care Designation" (GCD) medical orders to communicate a patient's general intent, specific interventions, and preferred locations of care. A validated SICP codebook was used to determine the frequency of conversation elements documented for (1) Goals and Values; (2) Prognosis/illness understanding; (3) End-of-life care planning and (4) GCD/Life-sustaining treatment preferences. Univariate and multivariate generalized linear models were used to analyze associations between quantity of elements documented and patient characteristics (age, gender, frailty, language spoken and GCD). RESULTS: Of 175 SICP conversations documented, in the univariate analysis more goals and values were documented for patients who understand/speak English (0.89; 95% CI: 0.14 - 1.63) and more content was recorded for patients with a non-resuscitative GCD focus ("Medical": 2.42; 95% CI: 1.51 - 3.33; "Comfort": 1.06; 95% CI: 0.24 - 1.88) although not in all domains. In the multivariate analysis, controlling for age, gender, language and frailty, the association between content scores and GCD remained highly significant. Patients with a non-resuscitative GCD had higher total domain scores than those with a resuscitative GCD ("Medical": 1.27 95% CI: 0.42-2.13; "Comfort": 2.67, 95% CI:1.71-3.62). CONCLUSION: The type of content documented by physicians after a SICP conversation is associated with the patient's goals of care.

Association Between Low Back Pain and Body Mass Index in Pakistani Population: Analysis of the Software Bank Data.

BACKGROUND: Obesity is a growing public health concern and is one of the leading causes of human suffering and disability worldwide. The number of overweight and obese people is dramatically increasing, and local data showed that low back pain (LBP) is more common in people with obesity, prolonged sitting jobs, psychological disorders, and lack of exercise. METHODS: This study was conducted in a cohort of 300 adult patients of either gender who visited a pain management clinic with LBP. Patient data were retrieved from the hospital software program and recorded in a pre-designed proforma. The data included the patient's age, gender, weight, height, BMI, comorbidities, site of pain, duration of pain, distribution of pain, severity of pain, history of spinal trauma, previous spinal surgery, and working diagnosis. RESULTS: Out of 300 patients with LBP, 185 (61.7 %) were female and 115 (38.3%) were male, of these, 224 (74.6%) were overweight or obese. One hundred and three (34.3%) had axial back pain and 197 (65.7%) patients had lumbar radicular pain. Linear regression analysis showed that 17% variability in pain scores in both genders can be explained by the increase in BMI. There is a statistically significant relationship, i.e. P=0.0005, exists between pain score and BMI. CONCLUSION: This study showed the strong association between obesity and LBP in the Pakistani population. Approximately, 75% were overweight or obese in our LBP population-based cohort and this association was stronger among women than men.

Rising resistance of urinary tract pathogens in children: a cause for concern.

BACKGROUND: Urinary tract infection (UTI) is one of the common infections in childhood. Prompt diagnosis and treatment reduces the risk of complications. The choice of antibiotic to treat UTI varies from region to region. Rational use and appropriately chosen antibiotic reduces the emergence of resistant uropathogens. OBJECTIVE: We investigated the resistance pattern of uropathogens for commonly used antibiotics to treat UTI locally. METHODS: Data was collected between 2009 and 2019 on all infants and children under 16 years of age with culture proven UTI. Results were compared with previously published figures between 2002 and 2008. RESULTS: A total of 1002 samples were analysed (91/year). Male to female ratio was 1:4.6. About 94% of the samples grew E. coli. As before, high resistance rates were recorded to Amoxicillin and Trimethoprim (Z = -0.325: P = 0.7452; not significant). Overall, average resistance has decreased for Nitrofurantoin from 10% between 2002 and 2008 to 5.84% between 2009 and 2019 (Z = 3.002: P = 0.0027). On the other hand, Cefalexin resistance has increased from 7.4 to 14.56% between the two study periods (Z = -4.2: P = < 0.0002). CONCLUSION: Despite rising resistance rates, we recommend that Cefalexin should cautiously remain the antibiotic of choice for empirically treating uncomplicated urinary tract infections in secondary care pending urine culture. Nitrofurantoin should be reserved for treating non-coliform/atypical UTIs or multi-drug resistant UTIs. There is an ongoing need for clinicians in all geographic regions to continue to monitor antibiotic resistance rates every few years.

Effect of necrotrophic fungus and PGPR on the comparative histochemistry of Vigna radiata by using multiple microscopic techniques.

Rapid advances in the field of pathogen detection have opened new opportunities and better understanding for their management approaches. Aim of this study was to elucidate histopathological observations of different tissues affected by Macrophomina phaseolina and to observe the defense responses of plant growth promoting rhizobacteria (PGPR) in mungbean plants. Sections of the stem and root were prepared and stained with ferric chloride, Lugol's iodine and Wiesner's reagent and were then observed under multiple microscopic techniques. Results revealed that both pathogen and PGPR produce responses on the plant that include colonization of xylem vessels by hyphae and sclerotia, hypertrophy and hyperplasia of the cells, destruction of xylem fibers and amyloplasts in parenchymatous cells; and production of gels by the plant were observed. There was a significant increase in lignin and phenolic compounds deposition in stem and root sections of PGPR treated and non-treated mungbean plants. Whereas the soil amended with PGPR showed very less to no starch production. Moreover, production of gels and gums were also observed in both stem and root sections. Compared to light microscopy, scanning electron microscope provided greater depth of focus and resolution of the pathogen attack on plant tissues, associated bacteria. As a whole, the data demonstrated that inoculation of PGPR can be an effective strategy to stimulate plant growth and they could significantly activate disease resistance against M. phaseolina.

Muslim perspectives on advance care planning: a model for community engagement.

BACKGROUND: Advance care planning is the process of communicating and documenting a person's future health care preferences. Despite its importance, knowledge of advance care planning is limited, especially among the Islamic community. In addition, little is known about how the Islamic community views advance care planning in the context of their religious and cultural beliefs. OBJECTIVES: We aimed to increase knowledge of the importance of advance care planning, to improve health care provider and public knowledge, and to encourage dialogue between the community and health care providers. METHODS: We organized a community event and assembled a multi-disciplinary panel. Through a moderated discussion, the panel members offered their perspectives of advance care planning within a Muslim context. RESULTS: Approximately 100 individuals attended the event including community members, health care providers, medical students, and faith leaders. More than 90% of respondents rated the event as very good or excellent, found the session useful and were encouraged to reflect further on advance care planning. CONCLUSION: This event was successful in raising awareness about advance care planning within the Islamic community as well as educating health care providers on Islamic views. This model of community and health care provider engagement may also be beneficial for other faith groups wishing to discuss advance care planning within their respective religious and cultural contexts.

Urate Nephropathy from Tumor Lysis Syndrome in an Undiagnosed Case of Prostate Cancer.

Prostate cancer can masquerade as just normocytic anemia and thrombocytopenia, thrombotic thrombocytopenic purpura (TTP), hemolytic uremic syndrome (HUS), or tumor lysis syndrome (TLS). We are reporting an intriguing case of metastatic prostate cancer which remained undiagnosed until the patient showed signs of tumor lysis syndrome (TLS), leading to urate nephropathy requiring urgent hemodialysis. Tumor lysis syndrome is an oncological emergency but an exceedingly rare complication in non-hematological malignancies, including prostate cancer. It is challenging to recognize features of TLS in a case such as this with an unknown diagnosis. In the case of an established diagnosis of malignancy, however, checking baseline renal function, uric acid, lactate dehydrogenase (LDH), potassium, and phosphate to monitor for TLS as well as considering urate lowering therapy can help prevent adverse outcomes.

Varying Architecture of Heat Shock Elements Contributes to Distinct Magnitudes of Target Gene Expression and Diverged Biological Pathways in Heat Stress Response of Bread Wheat.

The heat shock transcription factor (HSF) binds to cis-regulatory motifs known as heat shock elements (HSEs) to mediate the transcriptional response of HSF target genes. However, the HSF-HSEs interaction is not clearly understood. Using the newly released genome reference sequence of bread wheat, we identified 39,478 HSEs (95.6% of which were non-canonical HSEs) and collapsed them into 30,604 wheat genes, accounting for 27.6% wheat genes. Using the intensively heat-responsive transcriptomes of wheat, we demonstrated that canonical HSEs have a higher propensity to induce a response in the closest downstream genes than non-canonical HSEs. However, the response magnitude induced by non-canonical HSEs was comparable to that induced by canonical HSEs. Significantly, some non-canonical HSEs that contain mismatched nucleotides at specific positions within HSEs had a larger response magnitude than that of canonical HSEs. Consistently, most of the HSEs identified in the promoter regions of heat shock proteins were non-canonical HSEs, suggesting an important role for these non-canonical HSEs. Lastly, distinct diverged biological processes were observed between genes containing different HSE types, suggesting that sequence variation in HSEs plays a key role in the evolution of heat responses and adaptation. Our results provide a new perspective to understand the regulatory network underlying heat responses.
