 Perifascial areolar tissue (PAT) transplant is a technique in which a sheet of connective tissue on the fascia is harvested and transplanted to the wound bed. PAT engraftment fails when the exposed area of tendons, bones, or artificial materials is large. On the other hand, combination of tissue transplant and basic fibroblast growth factor (bFGF) improves the survival rate of the transplanted tissue.

Background: Perimembranous ventricular septal defect (VSD) can be classified as having trabecular, inlet, or outlet extension. The surgical approach used in patch closure depends on the which valve of the tricuspid valve to suture around and the avoidance of the specialized conducting system. This retrospective study evaluated the usefulness of the "En face view" method for classifying perimembranous VSD.

Article Synopsis
  • A study called JCOG1109 investigated the effects of thoracic duct (TD) resection on the survival of patients with esophageal squamous cell carcinoma, comparing different neoadjuvant treatments.
  • Among 601 patients, TD resection did not significantly improve overall survival when looking at the entire group, but some subgroups, particularly those treated with DCF and achieving a good pathological response, showed better survival with TD resection.
  • The findings suggest that TD resection may not benefit all patients, and the relationship between residual tumor burden after treatment and the impact of TD resection on survival needs further exploration.

  • Poor oral hygiene, seen as issues like dental caries and gingivitis, is linked to high blood pressure (BP) and arterial stiffness, but this study focuses on children and their mothers to explore these connections further.
  • The study involved 220 children and 217 mothers, assessing oral health and BP, using logistic regression to analyze how oral hygiene affects hypertension in both groups.
  • Findings showed that mothers with dental caries and significant dental plaque had higher rates of hypertension, which also correlated to high BP in their children, although children's arterial stiffness didn't show similar associations.

Background: Goblet cell carcinoid (GCC) of the appendix is a rare tumor characterized by neuroendocrine and adenocarcinoma features. Accurate preoperative diagnosis is very difficult, with most patients complaining mainly of abdominal pain. Computed tomography shows swelling of the appendix, so diagnosis is usually made incidentally after appendectomy based on a preoperative diagnosis of appendicitis.

Article Synopsis
  • - Using 3D image analysis, researchers studied changes in thoracic ossification of the posterior longitudinal ligament (OPLL) after surgery in 17 patients, finding that while overall volume didn't change much, 41% experienced a reduction in volume.
  • - Post-surgery results showed that although the width and length of OPLL increased significantly, its thickness decreased from 7.1 mm to 6.5 mm.
  • - The study concluded that thoracic OPLL becomes thinner and spreads out after surgery, with volumetric changes related to the movement of the dural sac.

Linalool and linalyl acetate are major components of lavender essential oil. These substances possess many biological activities, such as anti-inflammatory activity, analgesic and anxiolytic effects, and anticonvulsant properties, and they also induce modulation of neuronal activity in the autonomic nervous system. However, there are no reports of the direct effects of linalool on respiratory activity.

Background: Neoadjuvant therapy is the standard treatment for patients with locally advanced oesophageal squamous cell carcinoma (OSCC). However, the prognosis remains poor and more intensive neoadjuvant treatment might be needed to improve patient outcomes. We therefore aimed to compare the efficacy and safety of neoadjuvant doublet chemotherapy, triplet chemotherapy, and doublet chemotherapy plus radiotherapy in patients with previously untreated locally advanced OSCC.

Aging is a prominent risk factor for Alzheimer's disease (AD), but the cellular mechanisms underlying neuronal phenotypes remain elusive. Both accumulation of amyloid plaques and neurofibrillary tangles in the brain and age-linked organelle deficits are proposed as causes of AD phenotypes but the relationship between these events is unclear. Here, we address this question using a transdifferentiated neuron (tNeuron) model directly from human dermal fibroblasts.

Skin conductance (SC) is one of the indices commonly used in the autonomic Concealed Information Test (CIT), but SC amplitude is sometimes difficult to quantify. This study investigated the applicability of SC area to the CIT as an unambiguous measure of SC. Secondary analyses of an existing dataset indicated that SC area could be used to classify examinees according to their knowledge status, although the equivalence of its performance with the SC amplitude was inconclusive.

  • The study evaluates masticatory function in Japan through a food questionnaire that categorizes foods based on chewability, determining how well patients can eat different food groups.
  • The researchers conducted texture analysis on 93 food samples to objectively measure attributes like hardness and cohesiveness, finding significant variations due to cooking methods and food structure.
  • Results indicated a negative correlation between the masticatory index and food hardness, suggesting that chewability is closely linked to the physical properties of foods, including their cohesiveness and preparation methods.

Given the worldwide increase of forcibly displaced populations, particularly internally displaced persons (IDPs), it's crucial to have an up-to-date and precise tracking framework for population movements. Here, we study how the spatial and temporal pattern of a large-scale internal population movement can be monitored using human mobility datasets by exploring the case of IDPs in Ukraine at the beginning of the Russian invasion of 2022. Specifically, this study examines the sizes and travel distances of internal displacements based on GPS human mobility data, using the combinations of mobility pattern estimation methods such as truncated power law fitting and visualizing the results for humanitarian operations.

Plate fixation to zygomatic arch fractures carries the risk of facial nerve palsy and scarring of the cheek; however, without plate fixation, bone deviation or displacement may reoccur after surgery. Furthermore, zygomatic arch fractures combined with zygomatic body fractures are more postoperatively unstable than single zygomatic arch fractures. Few reports have focused on this combined fracture type, and no consensus has been reached regarding treatment.
