Macrobenthic assemblages of anthropogenically active subtidal zones contiguous to a marine protected area: a 9-year revisit.

Traditional taxonomical methods, an appropriate Benthic Biotic Index incorporating the Taxonomical Sufficiency concept and Biological Traits Analyses, were applied concurrently to evaluate the long-term variations in the benthic ecology of subtidal zones of a Marine-Protected Area subjected to prevalent oil and gas industrial activities. Our evaluation spanned two comparable surveys conducted 9 years apart (2010 vs. 2019).

Forecasting urban water demand using different hybrid-based metaheuristic algorithms' inspire for extracting artificial neural network hyperparameters.

This research offers a novel methodology for quantifying water needs by assessing weather variables, applying a combination of data preprocessing approaches, and an artificial neural network (ANN) that integrates using a genetic algorithm enabled particle swarm optimisation (PSOGA) algorithm. The PSOGA performance was compared with different hybrid-based metaheuristic algorithms' behaviour, modified PSO, and PSO as benchmarking techniques. Based on the findings, it is possible to enhance the standard of initial data and select optimal predictions that drive urban water demand through effective data processing.

The use of formal language as a strong sign of verbal autistic children in diglossic communities: The case of Arabic.

The current study aimed to investigate whether the use of formal language (Modern Standard Arabic [MSA]) by young children in diglossic Arab communities offers diagnostic insights, especially for verbal autistic children and to further explore this phenomenon. We used a cohort study design, with 4-6-year-old fluent first language Arabic-speaking children attending Arabic Kindergartens in two representative Kuwait governates. Reported cases for MSA use were assessed via a computer-based structured language test and corroborated cases were further assessed for exposure to sources of MSA, verbal IQ, temperamental characteristics, and autism spectrum disorder (ASD).

A retrospective unicentric cohort study, evaluating the impact of tranexamic acid on autologous free flap tissue reconstruction.

Background: The use of tranexamic acid (TXA) has been shown to be effective in reducing haemorrhage and mortality in numerous surgical settings. However, its use in plastic surgery has been limited due to misconceptions related to increased thrombotic events in microsurgery.

Methods: We performed a retrospective single-centre cohort study including any patients who underwent autologous free flap tissue transfer at Lister Hospital, Stevenage, from 1 January 2016-20 April 2022.

Benthic community resilience in two differently impacted tropical estuaries: Taxonomic vs functional approaches.

Estuaries experience incessant modifications due to various stressors causing shifts in the benthic species community structure and ecosystem functioning. Two tropical estuaries along Northwest India, exposed to varied intensities of anthropogenic perturbations, were sampled seasonally for two consecutive years. Specific aims were to assess, compare and link the macroinvertebrate taxonomic and functional structures, to evaluate the resilience of estuarine benthic ecosystems by employing the multiple-trait approach and to identify major influencing environmental drivers for patterns discerned.

Positive predictive value of ultrasound in correctly identifying an inguinal hernia: a single-centered retrospective pilot study.

Objectives: To determine the clinical utility of preoperative ultrasound imaging for predicting an inguinal hernia in need of surgery. In addition, we aimed to identify factors associated with false positive (FP) ultrasound examinations.

Methods: In this retrospective pilot study, we included all 175 patients who underwent inguinal hernia surgery in our hospital in 2019 and of whom a positive preoperative ultrasound examination of the groin area was available.

Treatment of pilocarpine-induced epileptic seizures in adult male mice.

Epilepsy is one of the most common neurological disorders affecting most social, economic and biological aspects of human life. Most patients with epilepsy have uncontrolled seizures and drug side effects despite the medications. Patients with epilepsy often have problems with attention, memory, and information processing speed, which may be due to seizures, underlying causes, or anticonvulsants.

Preliminary experience using the VITOM-3D system for microvascular anastomosis in DIEP free flap breast reconstruction.

Free tissue transfer has become routine practice in modern plastic surgery. The technique permits surgeons the flexibility to transfer the most suitable tissue for reconstruction. This has become possible largely due to the continued advances in microscope technology.

A Five-Year Retrospective Analysis of Diagnostic and Treatment Data of Flexor Sheath Infections: Can We Accurately Predict the Presence and Severity of Infection Prior to Surgical Washout?

Flexor sheath infections (FSIs) are soft tissue infections affecting the hand, which, if mismanaged, can have devastating consequences. Clinical assessment is key to diagnosis, with many relying on Kanavel cardinal signs as an aid. To prevent unnecessary operative intervention and the associated post-operative combined patient and healthcare burden, it is key that patients with FSIs are correctly identified.

Comparison of the distribution and phenology of Arctic Mountain plants between the early 20th and 21st centuries.

Arctic plants are adapted to climatic variability, but their long-term responses to warming remain unclear. Responses may occur by range shifts, phenological adjustments in growth and reproduction, or both. Here, we compare distribution and phenology of 83 arctic and boreal mountain species, sampled identically in the early 20th (1917-1919) and 21st centuries (2017-2018) from a region of northern Sweden that has warmed significantly.

Lump at the back of my tongue. The lingual thyroid-A case report and narrative review of literature.

Although the ectopic thyroid in adults is rarely symptomatic, biochemistry and imaging workup are essential. Treatment modality of choice is dependent on patient factors, institution factors and surgeon factors. The mainstay treatment involves hormone suppression treatment with exogenous thyroid hormone.

Electrochemical sensing: A prognostic tool in the fight against COVID-19.

The COVID-19 pandemic has devastated the world, despite all efforts in infection control and treatment/vaccine development. Hospitals are currently overcrowded, with health statuses of patients often being hard to gauge. Therefore, methods for determining infection severity need to be developed so that high-risk patients can be prioritized, resources can be efficiently distributed, and fatalities can be prevented.

Prevalence of and factors associated with self-reported noncompliance with mandatory seatbelt-use law while driving among adults in Kuwait.

Objectives: This cross-sectional study assessed the prevalence of self-reported noncompliance with mandatory seatbelt-use law and examined the factors associated with noncompliance with seatbelt-use while driving in adult working population in Kuwait.

Methods: During October 2017, 822 adults aged 21-60 years from 11 government ministries and departments were enrolled in this study. Data were collected using a pre-tested, structured, and self-administered questionnaire.

Challenging the Orthodoxy of Mandibular Reconstructions Comparing Functional Outcomes in Osseous versus Soft Tissue Reconstructions of the Posterolateral Mandible.

Background:  Appropriate reconstruction of the posterolateral mandible remains controversial. Both osseous and soft tissues are vital components for an overall successful outcome and are often combined in complex defects. Their respective effect on oromandibular function in the reconstruction of different degrees of mandibular defects has been less evaluated.

Intraoperative use of Mohs' surgery for the resection of major cutaneous head and neck cancer under general anaesthetic: Initial experiences, efficiency and outcomes.

Background: Complete excision of high-risk extensive non-melanoma skin cancers in the head and neck is paramount to achieving loco-regional control. However, achieving clear margins still remains a significant challenge. Mohs' micrographic surgery (MMS) provides the most accurate method of intraoperative mapping and histological assessment of tumour margins.

A theory for bone resorption based on the local rupture of osteocytes cells connections: A finite element study.

In this work, a bone damage resorption finite element model based on the disruption of the inhibitory signal transmitted between osteocytes cells in bone due to damage accumulation is developed and discussed. A strain-based stimulus function coupled to a damage-dependent spatial function is proposed to represent the connection between two osteocytes embedded in the bone tissue. The signal is transmitted to the bone surface to activate bone resorption.

The use of computed tomography for the estimation of DIEP flap weights in breast reconstruction: a simple mathematical formula.

Background: Estimation of the volume of abdominal tissue is desirable when planning autologous abdominal based breast reconstruction. However, this can be difficult clinically. The aim of this study was to develop a simple, yet reliable method of calculating the deep inferior epigastric artery perforator flap weight using the routine preoperative computed tomography angiogram (CTA) scan.

Finite element prediction with experimental validation of damage distribution in single trabeculae during three-point bending tests.

There is growing evidence that information on trabecular microarchitecture can improve the assessment of fracture risk. One current strategy is to exploit finite element (FE) analysis applied to experimental data of mechanically loaded single trabecular bone tissue obtained from non-invasive imaging techniques for the investigation of the damage initiation and growth of bone tissue. FE analysis of this type of bone has mainly focused on linear and non-linear analysis to evaluate the bone's failure properties.

Improvised External Fixation-a Modification.

A modification is presented to a commonly used type of improvised external fixator for hand fractures. Our modified fixator is easy to apply and allows fracture manipulation in three dimensions after application, before the cement sets.

Reconstruction of large traumatic segmental defects of the femur using segmental allograft with vascularized fibula inlay.

Segmental defects of the distal femur following trauma pose a reconstructive challenge. A stable reconstruction capable of withstanding high forces while allowing early mobility is paramount. The Capanna technique of reconstruction combining allograft with vascularized bone graft provides such a construct and has been described for oncological resection.

Management of chyle leak post neck dissection: a case report and literature review.

Chyle leakage post head-and-neck resection is a rare but potentially life-threatening complication. Management may be problematic and prolonged. Recently, thoracoscopic ligation of the thoracic duct has emerged as a promising technique to definitively treat this difficult problem.

Anatomical variation in deep inferior epigastric pedicles and implications for harvest of lower abdominal flaps.

The transverse rectus abdominis musculocutaneous (TRAM) flap based on the deep inferior epigastric artery is useful in head and neck reconstruction as it provides substantial skin and soft tissue cover, and allows volume to be replaced in large defects. A major advantage is the anatomical reliability of the deep inferior epigastric pedicle. We report a case in which neither rectus abdominis muscles had a blood supply from the deep inferior epigastric artery, which necessitated a change in the planned reconstruction.

Long-term outcome of squamous cell carcinoma of the upper and lower limbs.

Cutaneous squamous cell carcinoma (SCC) is the second most common malignant skin tumour in the European population, with an annual estimated age-standardised incidence of 1-6 per 1000. After the head and neck, the upper and lower limbs are the most common sites affected with 14% of SCCs occurring in these areas. SCC has the potential to be a highly aggressive tumour but there are no recent studies looking at the long-term outcome of patients with extremity SCC.
