Comparative assessment of growth performance, heat resistance and carcass traits in four poultry genotypes reared in hot-humid tropical environment.

This study investigated the impact of heat stress on growth and carcass traits in four poultry genotypes-Giriraja, Country chicken, Naked Neck and Kadaknath reared in a hot and humid tropical environment. Birds from all genotypes had ad libitum access to feed and water while being challenged with consistently high environmental temperatures in the experimental shed. Daily diurnal meteorological data were recorded inside and outside the shed. The study specifically examined growth variables and carcass characteristics. Significant differences (p < 0.01) were observed in body weight and average daily gain at various intervals. Notably, feed intake showed significant differences (p < 0.01) across weeks, indicating interactions between genotypes and time intervals. The feed conversion ratio (FCR) varied significantly (p < 0.01), with the highest FCR recorded in the Kadaknath breed. Livability percentages were similar across groups, except for Giriraja, which had significantly lower livability (p < 0.01). Carcass traits, including dressing, wings, feathers and giblet percentages, showed significant differences among genotypes (p < 0.01). Hepatic mRNA expression of growth-related genes revealed numerical variations, with Naked Neck displaying the highest (p < 0.05) fold change in IGF-1 expression compared to other genotypes. The study recognized in the Naked Neck genotype to possess higher resilience in maintaining homoeostasis and uncompromised growth under heat stress, providing valuable insights for sustainable poultry farming in challenging environmental conditions.

Microcephalic primordial dwarfism with predominant Meier-Gorlin phenotype, ichthyosis, and multiple joint deformities-Further expansion of DONSON Cell Cycle-opathy phenotypic spectrum.

We report a patient with microcephalic primordial dwarfism with predominant Meier-Gorlin syndrome phenotype with ichthyosis and disabling multiple joint deformities in addition to classic features of the syndrome. The patient was a 10.5-year-old girl referred in view of short stature, joint deformities, and facial dysmorphism. There was history of intrauterine growth restriction and collodion like skin abnormality at birth. She had normal developmental milestones and intellect. On clinical evaluation, anthropometry was suggestive of proportionate short stature and microcephaly. There was abnormal posture due to spine and peripheral joint deformities, along with ichthyosis, facial, and digital dysmorphism. Skeletal radiographs showed radial subluxation, acetabular dysplasia and hip dislocation, bilateral knee joint dislocation, absent patellae, slender long bones with delayed bone age, and subluxation of small joints of hands and feet. Work up for metabolic bone disease and peripheral blood karyotype was normal. Whole exome sequencing revealed a pathogenic homozygous variant c.C1297T (p.Pro433Ser) in the exon 8 of DONSON gene. This report further expands the genotypic-phenotypic spectrum of the group of disorders known as Cell Cycle-opathies.

Homozygous PCDH12 variants result in phenotype of cerebellar ataxia, dystonia, retinopathy, and dysmorphism.

We report on a sib pair of Indian origin born of a consanguineous parentage with a novel phenotype of distinct facial dysmorphism, cerebellar ataxia, dystonia, and exudative retinopathy due to homozygous PCDH12 nonsense variations. cDNA studies showed >90% reduction in transcript levels in both patients, indicating nonsense-mediated decay and loss of function as the probable causative molecular mechanism of the phenotype.

A pilot comparison study of four clinician-rated atopic dermatitis severity scales.

BACKGROUND: There are multiple severity outcome measures for atopic dermatitis (AD). There is a need to compare the reliability of these measures. OBJECTIVES: To compare the inter-rater and intrarater reliability of the objective Scoring Atopic Dermatitis (oSCORAD), Eczema Area and Severity Index (EASI), Six Area, Six Sign Atopic Dermatitis (SASSAD) and Three Item Severity index (TIS); and to analyse the correlation between these outcome measures and the quality-of-life instruments Patient-Orientated Eczema Measurement, Dermatology Life Quality Index and Skindex-29. METHODS: Twelve patients with AD attended a 1-day scoring exercise by five trained dermatology clinicians. Inter-rater and intrarater reliability were assessed using the intraclass correlation coefficient (ICC). Correlation between clinician-rated and patient-reported measures was analysed using Spearman's rho. RESULTS: Regarding inter-rater reliability, EASI and SASSAD showed good reliabilities, with ICCs of 0·730 [95% confidence interval (CI) 0·500-0·900] and 0·680 (95% CI 0·440-0·880), respectively. However, the ICCs were poor for TIS and oSCORAD, with 0·497 (95% CI 0·233-0·785) and 0·498 (95% CI 0·234-0·785), respectively. Separate body surface area (BSA) component analyses showed that the oSCORAD BSA component contributed to its inter-rater variations. Regarding intrarater reliability, EASI and TIS showed excellent ICCs of 0·886 (95% CI 0·744-0·952) and 0·820 (0·614-0·923), respectively, while SASSAD showed a good reliability with an ICC of 0·720 (95% CI 0·424-0·878). However, the intrarater ICC was poor for oSCORAD, with 0·446 (95% CI 0·037-0·730). Regarding correlation with patient-reported measures, only SASSAD demonstrated moderate correlation with Skindex-29 (ρ = 0·611, P = 0·035). CONCLUSIONS: EASI demonstrated the highest inter-rater and intrarater reliability, supporting it as the optimal AD severity outcome measure.

Fabrication of Patient Specific Titanium Implants for Correction of Cranial Defects: A Technique to Improve Anatomic Contours and Accuracy.

Hard tissue cranial defects may result from traumatic or iatrogenic etiology and warrants adequate reconstruction to provide protection to the underlying brain and cosmesis. Various techniques have been described in the literature for fabrication of patient specific titanium cranial implants. The process of fabrication of titanium patient specific implants (PSI) can be broadly classified into indirect and direct techniques. With the improvements in the medical imaging and computational modeling, direct technique of computer assisted prefabricated patient specific implants have gained popularity. However indirect method of PSI fabrication hold some specific advantage. Here we describe a technique for fabrication of titanium PSI by combining the principles of direct and indirect methods for reconstruction of cranial defects.

The development and validation of the treatment of autoimmune bullous disease quality of life questionnaire, a tool to measure the quality of life impacts of treatments used in patients with autoimmune blistering disease.

BACKGROUND: Treatments for autoimmune blistering diseases have significant risk of medical complications and quality of life impacts during treatment, and it is difficult to differentiate these impacts from disease burden or the effects of treatment. OBJECTIVES: To develop a quality of life instrument specific to the effects of treatments used in patients with autoimmune bullous disease (AIBD). METHODS: A comprehensive item generation process was used to build a 45-item pilot Autoimmune Bullous Disease Quality of Life (ABQOL) questionnaire, distributed to 70 patients with AIBD. Experts in bullous disease refined the pilot ABQOL, selecting only those questions pertaining to the treatment effects. This pilot Treatment of Autoimmune Bullous Disease Quality of Life (TABQOL) questionnaire was administered to 70 patients, before factor analysis was performed to yield the final questionnaire of 17 questions. Validity and reliability were evaluated across a range of indices. RESULTS: Face and content validity were established through a comprehensive patient interview process, expert review and summaries of treatments used. The questionnaire was found to have appropriate correlation with the Dermatology Life Quality Index (r = 0.64) and the level of treatments used (P < 0.01), and was found to be responsive to overall variations in treatment burden. The TABQOL was also found to be a reliable instrument as evaluated by internal consistency (Cronbach α = 0.892) and test-retest reliability (r = 0.99). CONCLUSIONS: We have shown that the TABQOL questionnaire is a valid and reliable instrument that may to be used to measure treatment burden in AIBD and serve as an end point in clinical trials.

Feasibility, Sustainability, and Effectiveness of the Implementation of "Facility-Team-Driven" Approach for Improving the Quality of Newborn Care in South India.

OBJECTIVES: The primary objective of the study was to assess the feasibility and sustainability of the implementation of the point of care quality improvement (POCQI) methodology for improving the quality of neonatal care at the level 2 special newborn care unit (SNCU). Additional objective was to evaluate the effectiveness of the quality improvement (QI) and preterm baby package training model. METHODS: This study was conducted in a level-II SNCU. The study period was divided into baseline; intervention and sustenance phases. The primary outcome i.e., feasibility was defined as completion of training for 80% or more health care professionals (HCPs) through workshops, their attendance in subsequent review meetings and, successful accomplishment of at least two plan-do-study-act (PDSA) cycles in each project. RESULTS: Of the total, 1217 neonates were enrolled during the 14 mo study period; 80 neonates in the baseline, 1019 in intervention and 118 in sustenance phases. Feasibility of training was achieved within a month of initiation of intervention phase; 22/24 (92%) nurses and 14/15 (93%) doctors attended the meetings. The outcomes of individual projects suggested an improvement in proportion of neonates being given exclusive breast milk on day 5 (22.8% to 78%); mean difference (95% CI) [55.2 (46.5 to 63.9)]. Neonates on any antibiotics declined, proportion of any enteral feeds on day one and duration of kangaroo mother care (KMC) increased. Proportion of neonates receiving intravenous fluids during phototherapy decreased. CONCLUSIONS: The present study demonstrates the feasibility, sustainability, and effectiveness of a facility-team-driven QI approach augmented with capacity building and post-training supportive supervision.

Design and assessment of a penile fracture simulation model.

OBJECTIVE: To design and assess a novel penile fracture simulation model for teaching penile fracture repair. METHODS: We used a validated circumcision simulator to create a model. Foreskin for a circumcision was divided into two halves. A transverse slit ("simulated fracture") was created on one part of the first half of the foreskin (mimicking "tunica") and was applied over the penile model. A red jelly tablet ("clot") was placed underneath the cut. A second full-length of foreskin was applied over it to cover the defect. The model was assessed by participants and expert faculty at the Urology Simulation Boot Camp. Evaluation was performed using a 5-point Likert Scale questionnaire. Data was analysed using Microsoft Excel and IBM SPSS Statistics V25. The intra-class correlation was calculated using a "One-way random model". RESULTS: Twenty-two urology trainees and four experts participated in the evaluation. The majority of trainees strongly agreed (59%, n = 13) the model is useful for training with experts similarly agreeing in 75% of cases. The appearance of penile fracture was considered good by both trainees (68%, n = 14) and faculty (75%). Overall, the ability of the model to represent a realistic simulation of the task was considered excellent by 23% of participants and good by 64%. Personal confidence after simulation in managing a similar situation was considered high among trainees. The main difficulties reported were related to fascial planes and urethra. CONCLUSION: This is the first simulation model for penile fracture repair and has demonstrated face validity at a national urology bootcamp.

Cerebral Coenurosis Masquerading as Malignancy: A Rare Case Report from India.

Human coenurosis is a rare zoonotic disease caused by the larvae of Tinea multiceps seen in sheep-rearing countries. We report the case of a 63-year-old male who was referred to our hospital with a working diagnosis of skull base chondrosarcoma. Histopathological examination after surgical excision revealed characteristic feature of coenurus with multiple scolices invaginating from the outer cuticular layer. Coenuri are often mistaken for giant cysticercal cysts and hydatid cysts. Despite its wide prevalence in cattle, only two cases of human coenurosis are reported from India till date. We report the third case from India.

Whole exome sequencing identifies a novel 5 Mb deletion at 14q12 region in a patient with global developmental delay, microcephaly and seizures.

Rett syndrome is a neurodevelopmental disorder affecting the nervous, musculoskeletal and gastroenteric systems. Affected individuals show normal neonatal development for 6-18 months followed by sudden growth arrest, psychomotor retardation and a broad spectrum of clinical features. Sequence variants in MECP2 gene have been identified as the major genetic etiology accounting for 90-95% of patients. Apart from MECP2, pathogenic sequence variants and copy number variants of FOXG1 gene lead to congenital type of Rett syndrome which is a more severe form and characterised by absence of early normal development as seen in classical Rett syndrome. In this report we describe a female child with global developmental delay, microcephaly and myoclonic seizures harbouring a 5 Mb deletion in 14q12 locus resulting in deletion of single copy of brain specific genes FOXG1, PRKD1 and NOVA1. Whole exome sequencing ruled out any possible role of other pathogenic single nucleotide variants and/or indels as the etiology for the observed phenotype. However, copy number variation analysis from the whole exome data detected a ~ 5 Mb microdeletion at the long arm of chromosome 14q12 region. The deletion was confirmed through array Comparative Genomic Hybridization and validated by quantitative PCR. Further, parents were analysed for mosaicism through metaphase Fluorescence in-situ Hybridisation. Our report broadens the phenotype of atypical Rett syndrome and reiterates the role of exome sequencing not only in detection of point mutation/small indels but also for detection of large deletions/duplication in coding regions.

Antibody to a human DNA repair protein allows for cloning of a Drosophila cDNA that encodes an apurinic endonuclease.

The cDNA of a Drosophila DNA repair gene, AP3, was cloned by screening an embryonic lambda gt11 expression library with an antibody that was originally prepared against a purified human apurinic-apyrimidinic (AP) endonuclease. The 1.2-kilobase (kb) AP3 cDNA mapped to a region on the third chromosome where a number of mutagen-sensitive alleles were located. The cDNA clone yielded an in vitro translation product of 35,000 daltons, in agreement with the predicted size of the translation product of the only open reading frame of AP3, and identical to the molecular size of an AP endonuclease activity recovered following sodium dodecyl sulfate-polyacrylamide gel electrophoresis of Drosophila extracts. The C-terminal portion of the predicted protein contained regions of presumptive DNA-binding domains, while the DNA sequence at the amino end of AP3 showed similarity to the Escherichia coli recA gene. AP3 is expressed as an abundant 1.3-kb mRNA that is detected throughout the life cycle of Drosophila melanogaster. Another 3.5-kb mRNA also hybridized to the AP3 cDNA, but this species was restricted to the early stages of development.

From profound hypokalemia to life-threatening hyperkalemia: a case of barium sulfide poisoning.

We describe a 25-year-old man who was brought to the emergency department with skeletal muscle weakness, respiratory arrest, and rhabdomyolysis, as well as life-threatening hyperkalemia, after ingesting a depilatory containing barium sulfide (Magic Shave; Carson Products Co, Savannah, Ga). The findings of his physical examination were significant for hyporeflexia with marked weakness. He was in respiratory distress and required intubation and ventilatory support owing to progressive weakness of the respiratory muscles. His serum potassium level was 1.5 mmol/L. He was treated with intravenous and oral potassium. His serum potassium level peaked at 8.3 mmol/L and his serum creatine kinase level at 8286 IU/L. His acute respiratory weakness resolved with correction of the potassium concentration; his rhabdomyolysis responded well to hydration; and his renal function returned to normal. We also discuss the various pathophysiological findings in this case and compare our patient with another who, despite ingesting a similar amount of the same hair remover, did not develop any of the above complications.

Operator's ability at assessing a high-speed (air turbine) handpiece before use: an audit.

BACKGROUND: The 'high-speed' (air turbine) handpiece is used extensively across many dental disciplines and the ability of clinicians to detect faulty handpieces is essential. AIM: The primary aim of this audit was to determine the proportion of participants who could correctly identify unsafe handpieces. Secondary aims were to determine the proportion that had previous training on the topic and determine whether an educational video could improve scores. METHOD: Eighty participants completed the first round of audit. They were asked to inspect seven handpieces, five of which were faulty, with three being classed as unsafe. After the intervention (educational sessions and distribution of a video) a second round of audit was completed on 69 participants. RESULTS: The ability to detect the three unsafe handpieces increased from 10% to 44% over the two rounds of audit. In the second round the highest score obtained was by those who had received the intervention, 77%. The lowest score, 14%, was by those who had not received the intervention. Nine percent of participants in the first round stated they had previously had training on handpiece inspection and none of these participants identified the three unsafe handpieces. CONCLUSION: This audit has highlighted that there is a knowledge deficiency with regards to air turbine handpiece safety and inspection. We have shown that introduction of a simple education video can have an impact on dentists and students abilities to detect unsafe faults. We have already introduced this into the undergraduate curriculum in our school and we aim to also raise awareness within the dental community.

Nosocomial surgical infections: incidence and cost in a developing country.

Eight hundred twenty-nine patients were monitored for nosocomial surgical infections from January to December 1980 at the University Hospital of the West Indies. Two hundred twenty-five patients (27%) had 189 postoperative wound infections (POWI) and 295 other nosocomial infections, with an average of 2.1 infections per infected patient. The incidence of POWI was 22.8%, varying from 7.3% in clean to 82.2% in infected wounds. The most common organisms isolated were gram-negative bacilli and Staphylococcus aureus. The most frequent nosocomial infection other than POWI was urinary tract infection (27.8%). A statistically significant number of urinary tract infections and septicemias were associated with the use of medical devices such as indwelling urethral catheters and central venous pressure lines (p less than 0.001). Septicemia was frequently associated with operations on the lower gastrointestinal and hepatobiliary tracts (p less than 0.001). The postoperative stay of an infected patient was prolonged by an average of 18 days. The total excess cost of hospitalization for the infected patients was U.S. $170,000.

Histopathology and immunohistochemistry of the caecum in children with the Trichuris dysentery syndrome.

Caecal biopsy specimens from Jamaican children with the Trichuris dysentery syndrome (TDS) and age matched Jamaican controls were investigated by immunohistochemistry and by light microscopy. Biopsy specimens from all children (with TDS and controls) showed a mild to moderate increase in inflammatory cells. Except in the vicinity of the worm, where the epithelium was flattened, there was no other epithelial abnormality. Compared with controls, children with TDS had increased IgM lamina propria plasma cells and decreased intraepithelial T cells. There was also an increase in crypt epithelial cell proliferation. Lamina propria T cells (both activated and non-activated) were no more common in children with the Trichuris syndrome than controls. Epithelial cell HLA-DR and VLA-1 expression (which are increased in other colitides) were the same in both groups. Despite the presence of large worm burdens and chronic dysentery, therefore, only minor changes were seen in the caecal mucosa of children with TDS.

Oxidative stress, inflammation, and diabetic vasculopathies: the role of alpha tocopherol therapy.

The diabetic state confers an increased propensity to accelerated atherogenesis. In addition to the established risk factors, there is evidence for increased oxidative stress and inflammation in diabetes. Increased oxidative stress is manifested by increased lipid peroxidation (e.g. increased F2-isoprostanes) and increased DNA damage. Evidence for increased inflammation includes increased monocyte superoxide and pro-inflammatory cytokine release (IL-1, IL-6, and TNF-alpha), increased monocyte adhesion to endothelium and increased levels of plasma C-reactive protein, the prototypic marker of inflammation. Most importantly, alpha tocopherol therapy, especially at high doses, clearly shows a benefit with regards to LDL oxidation, isoprostanes and a decrease in inflammatory markers such as C-reactive protein, pro-inflammatory cytokines and PAI-1 levels. Thus, it appears that, in diabetes, alpha tocopherol therapy could emerge as an additional therapeutic modality.

Immunoepidemiology of intestinal helminthic infections. 3. Mucosal macrophages and cytokine production in the colon of children with Trichuris trichiura dysentery.

Mucosal macrophages and accessory cells have been studied by immunohistochemistry in the lamina propria of the colon of children with Trichuris trichiura dysentery syndrome (TDS). No difference was found in the numbers of cells recognized by the monoclonal antibodies CD11c, CD68, or RFD7 between TDS children and local controls. However, large numbers of cells were recognized by an antibody against calprotectin (an anti-bacterial glycoprotein found in tissue infiltrating-monocytes) in TDS colonic mucosa, but few in control colon. Large numbers of cells containing tumour necrosis factor alpha (TNF alpha) were also seen in TDS mucosa; cells isolated from TDS mucosa secreted more TNF alpha than cells from control mucosa; and children with TDS had high levels of circulating TNF alpha. Non-specific macrophage-mediated inflammation and local cytokine production may therefore play a role in the pathogenesis of TDS.

Meconium ileus: laparotomy without resection, anastomosis, or enterostomy.

During the 14 yr from 1965 through 1978, 49 infants presented shortly after birth with intestinal obstruction due to impacted meconium. Three of these patients did not have fibrocystic disease. Eight patients were cured by a Gastrografin enema. There were 18 patients who had complications that included associated atresia, volvulus, and/or peritonitis. Various operations were done including resection with either primary anastomosis or enterostomy or varieties of the foregoing. Twenty-three babies had the simple uncomplicated form of meconium ileus. Eleven of these underwent resection and six patients died. Twelve patients were treated by laparotomy, ileotomy through a purse-string suture and prolonged irrigations using acetylcysteine. Of this group only one succumbed. This latter course of management is recommended for patients with simple uncomplicated meconium ileus as it involves no resection, no enterostomy, nor any primary anastomosis.
