Transorbital penetrating intracranial injury involving bilateral frontal lobes with evisceration of right eye: A case report.

Key Clinical Message: Timely diagnosis, multidisciplinary surgical intervention, and appropriate imaging are crucial in managing transorbital-penetrating intracranial injuries (TOPIs), minimizing morbidity, and optimizing patient outcomes. Abstract: Transorbital-penetrating intracranial injuries (TOPIs) are rare occurrences with potential for severe neurological complications and high mortality rates. Prompt diagnosis and management are essential to mitigate adverse outcomes. Understanding injury patterns and employing appropriate imaging modalities are crucial for effective surgical planning and patient care. We present a case of a 22-year-old male mechanic who sustained a TOPI involving bilateral frontal lobes with evisceration of the right eye following a workplace accident with a metal cutter. Upon arrival at the emergency department, the patient exhibited vision loss in the right eye, proptosis, and a dilated pupil. Imaging studies revealed the trajectory of a metal arrow through the right orbital roof, necessitating surgical intervention. A multidisciplinary team performed bifrontal craniectomy with duroplasty to remove the foreign body and address associated injuries. Postoperatively, the patient received broad-spectrum antibiotics and anticonvulsants, leading to full recovery and discharge on postoperative day 10. TOPIs present unique challenges due to their rarity and potential for devastating consequences. Our case highlights the importance of timely diagnosis, meticulous surgical planning, and multidisciplinary collaboration in achieving favorable outcomes. Radiological imaging plays a crucial role in guiding treatment decisions and optimizing patient care. This report underscores the significance of early surgical intervention, antimicrobial therapy, and prophylactic measures in reducing morbidity and mortality associated with TOPIs.

Assessing the efficacy of celecoxib after tonsillectomy and/or adenoidectomy: A systematic review and meta-analysis of randomised control trials.

OBJECTIVES: Tonsillectomy and adenoidectomy are common surgical procedures that cause persistent pain, bleeding, and functional limitations. We aimed to investigate the efficacy of celecoxib compared with a placebo for managing post-tonsillectomy or adenoidectomy pain and other adverse events. DESIGN: Systematic review and meta-analysis. METHODS: We conducted a systematic literature search in the PubMed, Cochrane, and Google Scholar databases from inception until July 2023. Dichotomous outcomes have been reported as risk ratios (RR) while continuous outcomes were reported using mean differences (MD). A funnel plot was drawn to investigate publication bias. RESULTS: From 1394 records identified, 6 randomised double-blind trials comprising 591 participants undergoing tonsillectomy and/or adenoidectomy were eligible for inclusion. A high dose (400 mg) of celecoxib was effective in decreasing the pain score for 'worst pain' after the procedure (MD: -10.98, [95% CI: -11.53, -10.42], p < .01, I2 = 0%) while a low dose (200 mg) was not significantly effective (p = 0.31). For managing other outcomes such as vomiting (RR: 1.37 [95% CI: 0.69, 2.68], p = 0.37, I2 = 67%), diarrhoea (RR: 1.41, [95% CI: 0.75, 2.64], p = .29, I2 = 42%), dizziness/drowsiness (RR: 0.90, [95% CI: 0.71, 1.15], p = .48, I2 = 0%), functional recovery time (p = .74), and headache (p = .91), there was no significant difference between the group on celecoxib and the placebo group regardless of dosage. Finally, there was no significant difference (RR: 1.02, [95% CI: 0.91, 1.15], p = .69, I2 = 0%) in the effect of the intervention on minimum bleeding, moderate bleeding, and profuse bleeding. CONCLUSION: This meta-analysis provides robust evidence pooled from high-quality trials and raises questions about the efficacy of celecoxib for tonsillectomy and/or adenoidectomy, challenging existing perceptions.

Design of potent tyrosinase inhibiting N-arylated-4-yl-benzamides bearing 2-aminothiazole-triazole bi-heterocycles: mechanistic insight through enzyme inhibition, kinetics and computational studies.

By using a convergent methodology, a unique series of N-arylated 4-yl-benzamides containing a bi-heterocyclic thiazole-triazole core was synthesized and the structures of these hybrid molecules, 9a-k, were corroborated through spectral analyses. The in vitro studies of these multi-functional molecules demonstrated their potent mushroom tyrosinase inhibition relative to the standard used. The kinetics mechanism was exposed by lineweaver-burk plots which revealed that, 9c, inhibited mushroom tyrosinase non-competitively by forming an enzyme-inhibitor complex. The inhibition constant Ki calculated from Dixon plots for this compound was 0.016 µM. The computational study was also consistent with the experimental results and these molecules disclosed good results of all scoring functions and interactions, which suggested a good binding to mushroom tyrosinase. So, it was predicted from the inferred results that these molecules might be considered as promising medicinal scaffolds for the diseases associated with the over-expression of this enzyme.

Comparison of hydro-fiber silver dressing and 1% silver sulfadiazine dressing for treatment of pediatric burns.

Burn is a debilitating and devastating emergency with many physical and psychological sequelae. Essential steps in burn wound management include cleansing/wound debridement, application of topical antimicrobial and dressing of affected body areas. Objective of this study is comparison in effectiveness of Hydro-fiber Silver dressing and 1% silver sulfadiazine dressing in management of pediatric burn patients in terms of wound healing. After ethical approval, 264 patients were enrolled and divided into two groups. Patients were managed with hydro-fiber silver dressing in group A and 1% silver sulfadiazine dressing in group B. An experienced pediatric surgeon examined the wounds for re epithelialization and efficacy was labeled after 15 days. Out of 264 enrolled patients 148(56.06%) were males and 116(43.94%) were females. Mean age of patients was 3.73±2.34 years. Type of burn was Scald in 215(81.4%) patients and flame in 49(18.6%). Depth of burn was 2nd degree in 185(70.08%) patients and 3rd degree in 79(29.92%) patients. Mean TBSA was 19.93±9.62%. In group A the efficacy was achieved in 91(68.9%) patients whereas in group B the efficacy was achieved in 73(55.3%) patients (p-value<0.05). Hydro-fiber Silver dressing is significantly more efficacious as compared to 1% silver sulfadiazine dressing for treatment of pediatric burn.

Identifying Intermolecular Interactions in Single-Molecule Localization Microscopy.

Intermolecular interactions underlie all cellular functions, yet visualizing these interactions at the single-molecule level remains challenging. Single-molecule localization microscopy (SMLM) offers a potential solution. Given a nanoscale map of two putative interaction partners, it should be possible to assign molecules either to the class of coupled pairs or to the class of non-coupled bystanders. Here, we developed a probabilistic algorithm that allows accurate determination of both the absolute number and the proportion of molecules that form coupled pairs. The algorithm calculates interaction probabilities for all possible pairs of localized molecules, selects the most likely interaction set, and corrects for any spurious colocalizations. Benchmarking this approach across a set of simulated molecular localization maps with varying densities (up to ∼ 50 molecules µm - 2 ) and localization precisions (5 to 50 nm) showed typical errors in the identification of correct pairs of only a few percent. At molecular densities of ∼ 5-10 molecules µm - 2 and localization precisions of 20-30 nm, which are typical parameters for SMLM imaging, the recall was ∼ 90%. The algorithm was effective at differentiating between non-interacting and coupled molecules both in simulations and experiments. Finally, it correctly inferred the number of coupled pairs over time in a simulated reaction-diffusion system, enabling determination of the underlying rate constants. The proposed approach promises to enable direct visualization and quantification of intermolecular interactions using SMLM.

A Comprehensive Analysis of Conventional Acupuncture and Pharmacological Approaches for Cardiac Arrhythmias: An Umbrella Review.

With a global incidence of approximately 3.4% and an annual mortality rate of 3.7 million, cardiac arrhythmias (CAs) are a pressing global health issue. Their increasing prevalence, especially among older people, is intensifying the challenge for health care systems worldwide. This study aims to compare the safety and effectiveness of acupuncture and pharmacological treatments for CAs, addressing critical gaps in understanding optimal therapeutic approaches. A search of PubMed, EMBASE, and the Cochrane database of systematic reviews was performed to identify data compiled through September 2023 for this umbrella review. Randomized controlled trials (RCTs) as the foundation for meta-analyses and peer-reviewed systematic reviews were the primary focus of the literature search. The Grading of Recommendations Assessment, Development, and Evaluation method was used to assess the overall certainty of the evidence, whereas AMSTAR 2 and the Cochrane Collaboration tool were used to evaluate the quality of the included reviews. Following a comprehensive review, three systematic analyses of 27 RCTs were integrated. Acupuncture led to a slightly greater reduction in the recurrence rate of paroxysmal supraventricular tachycardia (SVT) compared to standard pharmaceutical therapy (risk ratio [RR], 1.06; 95% confidence interval [CI], 0.88-1.27; I2 = 56%; P = .55), although the difference was not statistically significant. In contrast, acupuncture significantly outperformed pharmacological treatment in the context of ventricular premature beats (VPBs) (RR, 1.16; 95 CI, 1.08-1.25; I2 = 0%; P < .0001). The reduction in paroxysmal atrial fibrillation (AF)/atrial flutter was increased with acupuncture, albeit without statistical significance (RR, 1.12; 95% CI, 0.88-1.42; I2 = 0%; P = .36). Acupuncture also led to a greater reduction in heart rate (HR) compared to pharmaceutical treatment despite notable heterogeneity and a lack of statistical significance (mean difference, -1.55; 95% CI, -41.37 to 38.28; I2 = 99%; P = .94). Adverse events were effectively managed, affirming the favorable safety profile of acupuncture. Our study suggests that acupuncture leads to a greater reduction in the recurrence rates of VPBs, AF, and atrial flutter but not significantly so in paroxysmal SVT or post-treatment HR. While promising for specific arrhythmias, the varying effectiveness of acupuncture underscores the need for further research and clinical assessment to determine its precise role and suitability in managing particular cardiac conditions.

Quantitative proteomics reveals the dynamic proteome landscape of zebrafish embryos during the maternal-to-zygotic transition.

Maternal-to-zygotic transition (MZT) is central to early embryogenesis. However, its underlying molecular mechanisms are still not well described. Here, we revealed the expression dynamics of 5,000 proteins across four stages of zebrafish embryos during MZT, representing one of the most systematic surveys of proteome landscape of the zebrafish embryos during MZT. Nearly 700 proteins were differentially expressed and were divided into six clusters according to their expression patterns. The proteome expression profiles accurately reflect the main events that happen during the MZT, i.e., zygotic genome activation (ZGA), clearance of maternal mRNAs, and initiation of cellular differentiation and organogenesis. MZT is modulated by many proteins at multiple levels in a collaborative fashion, i.e., transcription factors, histones, histone-modifying enzymes, RNA helicases, and P-body proteins. Significant discrepancies were discovered between zebrafish proteome and transcriptome profiles during the MZT. The proteome dynamics database will be a valuable resource for bettering our understanding of MZT.

Precision Genome Editing with CRISPR-Cas9.

The CRISPR/Cas9 system is a revolutionary technology for genome editing that allows for precise and efficient modifications of DNA sequences. The system is composed of two main components, the Cas9 enzyme and a guide RNA (gRNA). The gRNA is designed to specifically target a desired DNA sequence, while the Cas9 enzyme acts as molecular scissors to cut the DNA at that specific location. The cell then repairs the digested DNA, either through nonhomologous end joining (NHEJ) or homology-directed repair (HDR), resulting in either indels or precise modifications of DNA sequences with broad implications in biotechnology, agriculture, and medicine. This chapter provides a practical approach for utilizing CRISPR/Cas9 in precise genome editing, including identifying the target gene sequence, designing gRNA and protein (Cas9), and delivering the CRISPR components to target cells.

Stimulatory effects of smoke solution and biogas digestate slurry application on photosynthesis, growth, and methylation profiling of solanum tuberosum.

Biostimulants are obtained from various sources like plants, animals, microorganisms, and industrial by-products as well as waste material. Their utilization in agriculture practices is being increased that is giving positive results. The purpose of the current study was to use plant-derived smoke (SMK) solution and biogas digestate (BGD) slurry as biostimulant to elucidate their impact on potato (Solanum tuberosum) performance. The experiment was conducted in lab as well as field conditions, and SMK and BGD solutions were prepared in varying concentrations such as SMK 1:500, SMK 1:250, BGD 50:50, and BGD 75:25. Foliar applications were performed thrice during experiments and data were collected related to photosynthesis, growth, pigments, and genome-wide methylation profiling. Net photosynthesis rate (A) and water use efficiency (WUE) were found higher in SMK- and BGD-treated lab and field grown plants. Among pigments, BGD-treated plants depicted higher levels of Chl a and Chl b while SMK-treated plants showed higher carotenoid levels. Alongside, enhancement in growth-related parameters like leaf number and dry weight was also observed in both lab- and field-treated plants. Furthermore, DNA methylation profile of SMK- and BGD-treated plants depicted variation compared to control. DNA methylation events increased in all the treatments compared to control except for SMK 1:500. These results indicate that smoke and slurry both act as efficient biostimulants which result in better performance of plants. Biostimulants also affected the genome-wide DNA methylation profile that resultantly might have changed the plant gene expression profiling and played its role in plant responsiveness to these biostimulants. However, there is need to elucidate a possible synergistic effect of SMK and BGD on plant growth along with gene expression profiling.

Efficacy and safety of ciprofol versus propofol for induction and maintenance of general anesthesia: a systematic review and meta-analysis.

BACKGROUND: Propofol has been the gold standard for anesthesia induction and maintenance due to its rapid onset and favorable pharmacokinetic properties. However, the search for alternative agents with improved safety and efficacy has led to the emergence of ciprofol (HSK3486), a structural analog of propofol. This systematic review and meta-analysis aim to comprehensively assess the safety and efficacy of ciprofol compared to propofol for anesthesia induction and maintenance in adult patients undergoing surgical procedures. METHODS: This study included only double-arm RCTs in which participants were aged eighteen or older undergoing surgery. For the statistical analysis of the extracted data, we employed RevMan 5.4.1. RESULTS: Ciprofol demonstrated a promising trend of higher anesthesiologists' satisfaction during the induction phase (MD 0.14, 95%, CI - 0.28 to 0.56, p = 0.51), whereas Propofol was favored during maintenance. Propofol also exhibited advantages with a shorter time to successful anesthesia induction (MD 0.08 min, 95% CI 0.00 to 0.15, p = 0.04), and quicker attainment of full alertness (MD 0.11 min, 95% CI - 1.29 to 1.52, p = 0.87), suggesting its efficiency in clinical practice. Importantly, there were no significant disparities in the success rate of anesthesia. CONCLUSION: Both ciprofol and propofol demonstrate comparable efficacy and safety for anesthesia induction and maintenance in adult patients undergoing surgery. While propofol provides a faster onset of induction, ciprofol exhibits advantages in terms of pain management. Clinicians should consider these findings when selecting anesthetic agents, and tailoring choices to individual patient needs and clinical scenarios.

Simultaneous Transcatheter Closure of a Ventricular Septal Defect and Pulmonary Valvuloplasty: A Case Report.

BACKGROUND Congenital heart diseases (CHDs) are the most common form of birth defects, affecting the structure and function of neonatal hearts. Pulmonary valve stenosis (PVS) and ventricular septal defects (VSD) are 2 of the more prevalent forms, both of which can lead to significant morbidity if left untreated. The emergence of transcatheter techniques has revolutionized the therapeutic landscape, presenting minimally invasive yet effective alternatives to open-heart surgery and significantly reducing associated patient morbidity and recovery time. CASE REPORT The presented case details the management of a 19-year-old man with complex CHDs, highlighting the nuanced decision-making process that led to a transcatheter approach. The patient's clinical presentation, marked by symptoms reflective of significant cardiac compromise, demanded a tailored approach that utilized the latest advancements in non-surgical intervention. The successful closure of the VSD with an Amplatzer device and the resolution of PVS via balloon valvuloplasty were achieved without complications, showcasing the potential of these techniques in managing similar cases. The post-intervention period was marked by a noteworthy recovery, confirming the procedural efficacy and enhancing the patient's quality of life. CONCLUSIONS The favorable outcome of this case highlights the pivotal role of transcatheter interventions in treating complex CHDs and suggests a shift towards less invasive approaches in cardiac care. This case contributes valuable insights to the existing body of evidence, reinforcing the potential of transcatheter techniques to become the preferred treatment modality. With promising immediate and short-term results, these techniques highlight the need for continued research into their long-term efficacy and application across diverse patient demographics.

Evaluation of visual outcomes with toric intraocular lens implantation using digital marker during cataract surgery.

Objectives: To assess the visual improvement and mean residual astigmatism in patients who underwent cataract surgery with toric intraocular lens. METHODS: The retrospective, observational study was conducted at the Department of Ophthalmology, Aga Khan University Hospital, Karachi, and comprised data from January 1, 2018, to December 31, 2020, related to adult patients who had regular astigmatism of at least 0.75D and underwent cataract surgery with toric intraocular lens implantation using a digital marker. The patients were followed up on post-operative days 1, 7, 30, 90 and 180. Along with age, the degree of astigmatism was noted. The visual acuity was calculated pre- and post-operatively. The mean residual astigmatism was then noted for all patients post-operatively. Data was analysed using SPSS 22. RESULTS: The sample comprised 240 eyes of 177 patients; 99(55.9%) males and 78(44.1%) females. The mean age of the sample was 62.5±10.6 years. The mean unaided visual acuity improved post-operatively from 0.57±0.38 to 0.07±0.22 at 90 days. At the 30-day follow-up, mean residual astigmatism had reduced from 1.52±0.84 to 0.01±0.09 (p<0.001). The mean intraocular lens rotation from the intended axis was 0.73°±0.92° on day 30. CONCLUSIONS: Toric intraocular lens implantation using a digital marker could effectively reduce the post-operative cylinder, and improve the unaided visual acuity following cataract surgery.

TopDIA: A Software Tool for Top-Down Data-Independent Acquisition Proteomics.

Top-down mass spectrometry is widely used for proteoform identification, characterization, and quantification owing to its ability to analyze intact proteoforms. In the last decade, top-down proteomics has been dominated by top-down data-dependent acquisition mass spectrometry (TD-DDA-MS), and top-down data-independent acquisition mass spectrometry (TD-DIA-MS) has not been well studied. While TD-DIA-MS produces complex multiplexed tandem mass spectrometry (MS/MS) spectra, which are challenging to confidently identify, it selects more precursor ions for MS/MS analysis and has the potential to increase proteoform identifications compared with TD-DDA-MS. Here we present TopDIA, the first software tool for proteoform identification by TD-DIA-MS. It generates demultiplexed pseudo MS/MS spectra from TD-DIA-MS data and then searches the pseudo MS/MS spectra against a protein sequence database for proteoform identification. We compared the performance of TD-DDA-MS and TD-DIA-MS using Escherichia coli K-12 MG1655 cells and demonstrated that TD-DIA-MS with TopDIA increased proteoform and protein identifications compared with TD-DDA-MS.

Asthma prevalence among United States population insights from NHANES data analysis.

Asthma is a prevalent respiratory condition that poses a substantial burden on public health in the United States. Understanding its prevalence and associated risk factors is vital for informed policymaking and public health interventions. This study aims to examine asthma prevalence and identify major risk factors in the U.S. POPULATION: Our study utilized NHANES data between 1999 and 2020 to investigate asthma prevalence and associated risk factors within the U.S. POPULATION: We analyzed a dataset of 64,222 participants, excluding those under 20 years old. We performed binary regression analysis to examine the relationship of demographic and health related covariates with the prevalence of asthma. The study found that asthma affected 8.7% of the U.S. POPULATION: Gender emerged as a significant factor, with 36.0% of asthma patients being male and 64.0% female (p < 0.001). Individuals aged 60 and older having the highest asthma prevalence at 34.0%. Non-Hispanic whites had the highest prevalence at 46.4%, followed by non-hispanic blacks at 26.0%. In contrast, Mexican Americans and other hispanic individuals had lower rates, at 9.6% and 9.0%, respectively. Females were 1.76 times more likely to have asthma than males (p < 0.001). Obese individuals had a 1.74 times higher likelihood of current asthma compared to underweight individuals (p < 0.001). Notably, both Non-Hispanic Whites and Non-Hispanic Blacks showed higher odds of current asthma compared to Mexican Americans (with adjusted odds ratios of 2.084 and 2.096, respectively, p < 0.001). The research findings indicate that asthma is prevalent in 8.7% of the U.S. POPULATION: Our study highlights that individuals who are female, have low income, are obese, and smoke have the highest likelihood of being affected by asthma. Therefore, public health policies should prioritize addressing these risk factors in their preventive strategies.

Predictors of radioiodine (RAI)-avidity restoration for NTRK fusion-positive RAI-resistant metastatic thyroid cancers.

Context: Two-thirds of metastatic differentiated thyroid cancer (DTC) patients have radioiodine (RAI)-resistant disease, resulting in poor prognosis and high mortality. For rare NTRK and RET fusion-positive metastatic, RAI-resistant thyroid cancers, variable success of re-induction of RAI avidity during treatment with NTRK or RET inhibitors has been reported. Case presentation and results: We report two cases with RAI-resistant lung metastases treated with larotrectinib: an 83-year-old male presenting with an ETV6::NTRK3 fusion-positive tumor with the TERT promoter mutation c.-124C>T, and a 31-year-old female presenting with a TPR::NTRK1 fusion-positive tumor (and negative for TERT promoter mutation). Post larotrectinib treatment, diagnostic I-123 whole body scan revealed unsuccessful RAI-uptake re-induction in the TERT-positive tumor, with a thyroid differentiation score (TDS) of -0.287. In contrast, the TERT-negative tumor exhibited successful I-131 reuptake with a TDS of -0.060. Conclusion: As observed for RAI-resistance associated with concurrent TERT and BRAF mutations, the co-occurrence of TERT mutations and NTRK fusions may also contribute to re-sensitization failure.

Comparison of absolute renal uptake by using Tc-99m MAG-3 and Tc-99m DMSA.

PURPOSE: The purpose of this study is to compare the value of absolute renal uptake (ARU %) in patients by using Tc-99m MAG-3 and Tc-99m DMSA scan. MATERIAL AND METHODS: Absolute renal uptake is calculated using Tc-99m MAG-3 and Tc-99m DMSA in renal scintigraphy, Itoh and Tauex kidney depth methods used, respectively. n = 40 adult patients of both genders were included. All patients underwent Tc-99m MAG-3 and Tc-99m DMSA, respectively. RESULTS: The values of ARU (%) were calculated separately in selected patients n = 40, (left = 17, right = 23 normal functioning kidneys) by MAG-3 and DMSA. Absolute renal uptake (%) of Tc-99m MAG-3 in left kidneys was found to be 15.2 ±â€…3.4, with spilt renal function 79.2 ±â€…14.7 and ARU (%) in right kidneys 16.2 ±â€…3.4 with spilt renal function 77.5 ±â€…19. Absolute renal uptake of Tc-99m DMSA in left kidneys was 17.5 ±â€…3.2 and in right kidneys 17.9 ±â€…4.5 with spilt renal function 81.8 ±â€…10.7 and 79.3 ±â€…13.8 for left and right kidney, respectively. Statistical analysis showed strong Pearson correlation. CONCLUSION: Absolute renal uptake % was found to be more reliable in cases of bilateral compromised kidneys. ARU (%) calculated by Tc-99m MAG-3 solely can be used as predictor of renal function. The use of Tc-99m MAG-3 has more advantages than Tc-99m DMSA alone in renal scintigraphy as dynamic scintigraphy gives less radiation burden to patient, more information regarding renal function, and shorter stay time at hospital in comparison to static renal imaging. SRF % is less reliable than ARU (%).

Awareness regarding breast cancer amongst women in Pakistan: A systematic review and meta-analysis.

BACKGROUND: Breast cancer (BCa) is the most common cause of cancer death in Pakistan. In 2019, Pakistan saw the highest global BCa-associated death rate. But do Pakistani women know about the various aspects of BCa? And how prevalent are BCa screening methods amongst Pakistani females? These questions formed the basis for our study. METHODS: We conducted this review in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. On September 1, 2023, we searched PubMed, Embase, Scopus, and Google Scholar, and performed a citation search to search for eligible studies published in 2010 or after, using the following terms: "breast cancer" and "Pakistan". Observational studies that evaluated BCa awareness and/or practice amongst Pakistani females who were not associated with medicine were eligible. We used the National Institutes of Health quality assessment tool to assess the risk of bias. We conducted a proportion meta-analysis to calculate pooled prevalences for variables. RESULTS: Responses from 9766 Pakistani women across 18 included studies showed alarmingly low levels of BCa knowledge: risk factors, 42.7% (95% CI: 34.1%-51.4%); symptoms, 41.8% (95% CI: 26.2%-57.5%); diagnostic modalities, 36.3% (95% CI: 23.1%-49.4%); treatments, 46.6% (95% CI: 13.5%-79.8%). Prevalence of breast self-examination (BSE) and ever having undergone a clinical breast exam (CBE) was 28.7% (95% CI: 17.9%-39.6%) and 15.3% (95 CI: 11.2%-19.4%), respectively. BCa knowledge was significantly associated with better educational status, age, and socioeconomic status. CONCLUSION: On average, only two in five Pakistani women are aware of one or more risk factors, symptoms, or diagnostic modalities. Approximately one in two women know about possible BCa treatment. Less than one in three women practice regular BSE, and less than one in five women have ever undergone a CBE.

Cellulolytic and Ethanologenic Evaluation of Heterotermes indicola's Gut-Associated Bacterial Isolates.

Cellulose is the basic component of lignocellulosic biomass (LCB) making it a suitable substrate for bioethanol fermentation. Cellulolytic and ethanologenic bacteria possess cellulases that convert cellulose to glucose, which in turn yields ethanol subsequently. Heterotermes indicola is a subterranean termite that causes destructive damage by consuming wooden structures of infrastructure, LCB products, etc. Prospectively, the study envisioned the screening of cellulolytic and ethanologenic bacteria from the termite gut. Twenty six bacterial strains (H1-H26) based on varied colonial morphologies were isolated. Bacterial cellulolytic activity was tested biochemically. Marked gas production in the form of bubbles (0.1-4 cm) in Durham tubes was observed in H3, H7, H13, H15, H17, H21, and H22. Sugar degradation of all isolates was indicated by pink to maroon color development with the tetrazolium salt. Hallow zones (0.42-11 mm) by Congo red staining was exhibited by all strains except H2, H7, H8, and H19. Among the 26 bacterial isolates, 12 strains were identified as efficient cellulolytic bacteria. CMCase activity and ethanol titer of all isolates varied from 1.30 ± 0.03 (H13) to 1.83 ± 0.01 (H21) umol/mL/min and 2.36 ± 0.01 (H25) to 7.00 ± 0.01 (H21) g/L, respectively. Likewise, isolate H21 exhibited an ethanol yield of 0.40 ± 0.10 g/g with 78.38 ± 2.05% fermentation efficiency. Molecular characterization of four strains, Staphylococcus sp. H13, Acinetobacter baumanni H17, Acinetobacter sp. H21, and Acinetobacter nosocomialis H22, were based on the maximum cellulolytic index and the ethanol yield. H. indicola harbor promising and novel bacteria with a natural cellulolytic tendency for efficient bioconversion of LCB to value-added products. Hence, the selected cellulolytic bacteria can become an excellent addition for use in enzyme purification, composting, and production of biofuel at large.
