Cancer metastasis to the pituitary gland is rare, but in most cases, it originates from a late-stage breast tumor or lung cancer. The most common symptoms of metastasis to the pituitary gland are diabetes insipidus and visual disturbance. The common site of metastasis is the posterior portion of the pituitary gland because it is highly vascularized. Metastases to this site represent 1% of all tumors [1]. Metastasis to the pituitary gland is difficult to diagnose by hormonal analysis and magnetic resonance imaging of the brain and requires biopsy for confirmation [2].
Cancer is a serious disease that affects deeply and painfully not only the child who has cancer but also their parents. Through this study, we describe the different aspects of the impact of pediatric cancer on parents: the psychological, social, and family impact to offer optimal care to these parents. Results: mothers represent 82.5% of the participants in our survey. More than sixty percent were of urban origin. The average time from diagnosis to parents’ assessment was 7.3 months. This announcement was made by doctors in 87.5% of cases. Conscious denial of cancer when it was announced was reported in 75% of parents. The social impact of pediatric cancer on parents was significant. The child’s illness was experienced as a very significant psychological distress; all of the parents said they had given up on important projects after their children’s illness. The psycho-emotional impact was represented by feelings of guilt in 37.5% and incapacity for illness in 30%. Forty-two percent felt tensions on the marital level with significant repercussions on the couple with a type of destabilization in 60% of cases. The parent’s relationship with the rest of the family, especially siblings, was marked by neglect and anxiety in 35% and 26% respectively.Conclusion: The discovery of pediatric cancer induces various feelings that will inevitably have an impact on the parents of the affected child. Understanding the different aspects of this impact on the parents’ psycho-social, emotional and family experiences will make it possible to offer optimal care.
Most parents in affluent countries receive information about neonatal jaundice from instructional pamphlets and/or verbally from nurses before discharge. Predischarge protocols, content and delivery of information for parents, and screening for jaundice vary among hospitals. Newborns are usually screened either visually or with a transcutaneous monitor to estimate the intensity of jaundice. The timing of follow-up is guided by the newborn’s clinical status, age at discharge and risk of developing significant hyperbilirubinemia based on an hour-specific bilirubin level [1,2].
Different methods for calculating and estimating a safe face pressure were proposed by researchers, which have some advantages and disadvantages. In each of these methods, some related parameters such as soil geotechnical parameters, dimensions of the tunnel, and geological conditions are used. In these methods, using a series of mathematical or empirical functions, the face pressure is calculated. In this study, the face displacements were obtained using the finite difference numerical FLAC3D, the COB (Netherlands Underground Science Center) empirical, and the Leca and Dormieux (1990) analytical methods. The impact of the COB method on different ground stiffnesses is studied and evaluated. The reference case of this research is the Tehran Metro Line 6 tunnel (excavation radius: 4.6 m).

Carbonic anhydrase VI (CA VI) catalyzes the reversible hydration of carbon dioxide in saliva with possible pH regulation, taste perception, and tooth formation effects. Objective: The aim of this work was to undertake a systematic review regarding the relationship between the expression/activity of CA VI in saliva and in dental biofilm and caries experience. Study design: Five databases were searched until February 2020. The composition was based on the PRISMA statement and on the PICOS model. First author, year, subject characteristics, analysis performed, outcome, measures & variables were extracted. The used terms were “carbonic anhydrase VI”, “saliva”, “dental biofilm” and “dental caries”.Results: Five studies in the English language were selected for this systematic review and the main discussed topics were the expression/activity of CA VI in saliva and/or in the dental biofilm of children, and its relationship with dental caries. Conclusion: Salivary carbonic anhydrase plays an important role in the caries dynamics process since there is an association between the expression/activity of CA VI in saliva and the experience of caries. Thus, this protein can predict the risk of dental caries in young patients.
Given improvements in neonatal care and the increased survival rates of infants born pre-term, Cortical Visual Impairment (CVI) is now the leading cause of visual impairment (VI) in the developed world. In this study, Step VEPS, transient VEPS and Vernier Sweep VEPs all demonstrated unbiased relationships with Preferential looking (PL) cards over the whole range of Visual Acuity (VA) in children with CVI, allowing equations for clinical use to be derived. The results also suggested that a slower, vernier steady-state stimulus of 80% contrast and presented with the Step VEP algorithm could further improve VA agreement with PL and optimise developmental sensitivity. An eye tracking device has proved very useful in the clinical assessment of this cohort. It is also now known that children can have good VA and CVI, and that sweep VEPS can highlight higher processing deficits. As well as negative findings, compensatory neuroplasticity is thought to occur during maturation and it is now realistic to study this mechanism, and other age-related changes across VI with functional tests and neuroimaging (including VEPS). A cross-sectional study of adults would highlight CVI’s ultimate functional limitations.

Background: Intracerebral hemorrhage (ICH) is one of the most feared complications after brain tumor surgery. Despite several factors being considered to influence bleeding, an increasing number of clinical studies emphasize that hemostatic disorders, developed during surgical aggression and tumor status, could explain unexpected ICH. The objective of this prospective study was to evaluate the influence of perioperative D-dimer levels on ICH after brain tumor surgery. Methods: This prospective, observational, 18-month study, at a single third-level hospital, included all consecutive adults operated on brain tumors and postoperative stay in an intensive care unit. Three blood samples evaluated D-dimer levels (A-baseline, B-postoperative and C-24 hours after surgery). The normal range considered was 0-500ng/ml. ICH, as a primary outcome, was defined as bleeding that generates radiological signs of intracranial hypertension either by volume or by mass effect on the routine CT scan 24 hours after surgery. Other tumor features and hemostasis variables were analyzed. Chi-squared and Fisher’s exact test were used in the inferential analysis for qualitative variables and Wilcoxon and T-Test for quantitative ones. P-value < 0.05 was considered significant for a confidence interval of 95%. Results: A total of 109 patients operated on brain tumor surgery were finally included, 69 male (63,30%) and 40 female (36,70%), with a mean age of 54,60 ± 14,75 years. ICH was confirmed in 39 patients (35,78%). Their average of DDimer was A-1.526,70 ng/dl, B-1.061,88 ng/dl, and C-1.330,91 ng/dl (A p0.039, B p0,223 C p0.042, W-Wilcoxon test). The male group was also associated with ICH (p0,030 X2 test). Of those 39 patients with ICH, 30 in sample A (76,9%), 20 in sample B (51,28%) and 35 in sample C (89,74%) had a D-dimer > 500 ng/dl (p0,092, p1, p0,761 X2 test) and the relative risk of developing a postoperative hematoma in this patients was increased 0,36-fold presurgery, 0,25-fold postsurgery and 0,40-fold 24hours after surgery. D-dimer variation, had no statistical significance (p0,118, p0,195, p0,756 T-test). Platelets and prothrombin activity were associated with D-dimer levels only in sample A (p 0,02 and p 0,20, W Wilson). Conclusion: High levels of perioperative D-dimer could be considered a risk marker of ICH after brain tumor surgery. However, more studies would be worthwhile to confirm this association and develop primary prevention strategies for stroke.

Nanotechnology is starting the characterization, fabrication, and possible applications of numerous materials at the Nano-scale. Over the last few eras, nanomaterials provide a platform for researchers from diverse arenas due to the high surface-to-volume ratio and other novels, and new significant belongings. Zinc oxide nanoparticles are receiving diverse biomedical applications because of their distinctive antimicrobial, antioxidant, anticancer, antifungal, antileishmanial, anti-larvicidal, wound healing, anticholinergic, and anti-diabetic properties. Different physical and chemical approaches have been used to synthesize zinc oxide nanoparticles, but these methods cause ecotoxicity and are time-consuming and costly. Therefore, there is a need for more eco-friendly, cost-effective, and safe methods. Such biogenic Zinc oxide nanoparticles offer more advantages over other physiochemically synthesized methods. In this review, we have summarized the recent literature for the understanding of the green synthesis of Zinc oxide nanoparticles, their characterization, and their various biomedical applications.
Background/Introduction: WHO recommended ‘ready to use therapeutic food’ (RUTF) for community-based management (CMAM) of severely malnourished children (SMC). This is often rejected by children. The objective is to identify and map the locally produced and socio-culturally acceptable food items to treat SMC. Methods: Through community participation, eight varieties of MAHAN Local therapeutic foods (LTFs) were prepared by tribal females at our center as per WHO norms with a shelf life of 4 weeks. LTFs with micronutrients were given at the feeding centers in the villages under supervision 3 - 4 times a day. Results: Multiple, palatable, culturally acceptable, safe, feasible with local womanpower, and cost-effective recipes were developed. Hence, our LTFs are qualitatively superior to other therapeutic foods. This mapping exercise provides a ready reference to other government or non-government organizations for CMAM. Conclusion: MAHAN-LTF is a multiple, palatable, generalizable, and sustainable therapeutic food and are being used in other tribal blocks of India.
The mental health impact caused by COVID-19 on adolescents was reviewed, and due to limited data, adult results were included, to support our assertion that additional mental health resources are needed for both adult and young people. Positive gains would include improved socio-emotional skills, a decrease in maladaptive behaviors contributing to the disruption in interpersonal relationships and lifetime achievements, suicide attempts and psychopathology, persistent mental health concerns found in the juvenile justice and foster care systems and substance use addiction later in adulthood (The American Psychological Association, 2019; Garber & Weersing, 2010; Office of Juvenile Justice and Delinquency Prevention, n.d.; Tomasello, 2018;). Geiger & Davis, 2019, found that 13% or 3.2 million United States (U.S.) teenagers aged 12 - 17 years old experienced at least one major depressive episode with the depression rate increasing 59% from 2007 to 2017. Therefore, we assert that developing programs to overcome barriers to mental health aid can reduce instances experienced in adolescence and adulthood.

Cerebral brain injuries (CBIs) account for up to 20% of all injuries in boxing. Approximately 97% of sports-related brain injuries are mild, their neurological symptoms are unexpressed, and young, strong, highly motivated athletes tend to dismiss the severity of their injuries. This may lead to an underestimation of the severity and extent of brain injuries. Changes in computed tomography (CT) and magnetic resonance imaging (MRI) in mild traumatic brain injury are absent in the early stages, making diagnosis difficult. Frequent repetitive traumatic brain injuries, including mild brain injuries, can result in functional and structural brain lesions that affect athletes’ performance and, in the long term, significantly impair their quality of life. Also, the consequences of cerebral brain injuries, including mild brain injury, can be affected by the individual condition of the Circle of Willis.

Objective: Pelvic masses can be classified as low risk (likely benign) and high risk (likely malignant) based on an initial clinical risk assessment, which involves a detailed history, physical exam, basic laboratory tests, and imaging. In recent years, the Risk of Ovarian Malignancy Algorithm (ROMA), which combines CA125, HE4 and menopausal status, has emerged as a powerful tool in the classification of pelvic masses and triage of patients to either a generalist gynecologist or a gynecologic oncologist for management. The objective of this study was to evaluate whether the use of ROMA, alone or in combination with Initial Clinical Risk Assessment (ICRA), provides cost savings compared to triage based on ICRA alone.Methods: A health-economic decision model was developed to assess clinical and cost differences associated with three different clinical pathways of risk assessment for a pelvic mass: ICRA alone, ROMA alone, or ICRA + ROMA in combination. Using previously reported accuracy rates and patient characteristics from a prospective, multicenter, blinded clinical trial, total healthcare costs were modeled for each clinical pathway using the Medicare 2020 reimbursement rates.Results: A total of 461 patients with pelvic masses were included with 10.4% ultimately diagnosed with epithelial ovarian cancer. Total healthcare costs for patients with benign disease, EOC, or low malignant potential tumors (LMP) (n = 441) triaged using ROMA alone were 3.3% lower than when triaged using ICRA alone. While lab costs increased 55% using ROMA, the use of ROMA alone resulted in a 4% decrease in laparoscopy costs and a 3.1% decrease in laparotomy costs compared with ICRA alone. Similarly, total costs associated with a combination of ICRA + ROMA were 3.9% lower than total costs associated with ICRA alone. The model also predicted a 63% reduction in repeat surgeries resulting from false negative ICRA when using ROMA to triage patients.Conclusion: Triage of women with pelvic masses using the more sensitive ROMA score lowers overall healthcare costs compared to ICRA alone. With fewer false negative results than ICRA alone, the ROMA score improves initial detection of malignancy and reduces second surgical treatments in women with pelvic masses.

We describe a case of thoracic endometriosis in a patient with a repeated episode of spontaneous pneumothorax. Investigations revealed diaphragmatic fenestrations and right-sided pleural and lung endometriosis. Considering the ultrasound evidence of pelvic endometriosis, the patient was scheduled for multidisciplinary surgical management, to treat in one step thoracic and pelvic endometriosis.
The COVID-19 pandemic resulted in public health measures and fewer viral infections, which trigger the nephrotic syndrome. Our objectives were to characterize the effect of the COVID-19 pandemic on children with nephrotic syndrome. This single-center retrospective chart review compared children with nephrotic syndrome one year before the pandemic with the first wave of the pandemic. Epidemiologic events, clinical characteristics, and health care utilization were compared using paired t-tests, Fisher’s exact tests and Wilcoxon Rank Sum tests. Among 96 children the mean age was 10.7 ± 5.28 years. The distribution was minimal change disease (16.7%), focal segmental glomerulosclerosis (12.5%), membranous nephropathy (1%) and not biopsied (69.8%). Medication responsiveness was steroid-sensitive (25%), frequently relapsed (54%) and steroid-resistant (20.8%). There were 14 new diagnoses of nephrotic syndrome pre-pandemic and 18 during the pandemic. Fewer relapses during the pandemic were likely due to fewer viral illnesses from public health measures during the pandemic.

Monilinia laxa is a fungus that causes brown rot in stone fruit. Immature green fruits in the first stage of fruit development (stage I) are generally susceptible. To investigate the relationship between the physical characteristics of immature fruit and susceptibility to M. laxa, we characterized the progeny, derived from a clone of wild peach (Prunus davidiana) crossed with two commercial nectarines (Prunus persica) varieties, through laboratory infection, transpiration monitoring and stomata counting. Two types of fruit infections were observed - ‘classic’ brown rot and ‘clear spot’ symptoms - which have not previously been described in the literature. The number and density of stomata did not explain the observed variability of infection in the progeny. However, surface conductance was positively correlated with infection level. This study provides experimental evidence partially linking physical fruit characteristics to brown rot infection at the immature fruit stage. The role of delayed cuticle deposition in susceptibility to brown rot of immature fruit is discussed.
The depletion of non-renewable resources is followed by severe ecological and social impacts, and the heavy usage of raw, virgin resources leaves significant, long-lasting footprints. The transition to a more circular economy, where the value of products, materials and resources is maintained and circulated (by recycling activities) in the economy for as long as possible, is an essential contribution to the EU’s efforts to develop a sustainable, low carbon, resource efficient and competitive economy. In this context, ecological solutions consisting of materials that help carbon sequestration and necessitate small amounts of energy for production are becoming increasingly popular from a building construction point of view, namely: The raw material is cheap and in large quantities; has low thermal conductivity; are from a renewable source. The paper presents an analysis of IZOMIN an innovative thermal insulating product made from renewable or recycled resources and their main technical properties, the purpose being to inform the market in order to increase the present level of technical knowledge and technologies used to facilitate the implementation of buildings with high energy efficiency.

Background: Collagenase is commonly used to isolate the stromal vascular fraction (SVF) or adipose tissue-derived stem cells (ADSCs) from human adipose tissue. Enzymatic breakdowns may be a substantial manipulation according to the classifications of medical regulatory authorities. This study investigates the possible effects of human adipose tissue dissociation with collagenase on in vitro function and behavior of ADSCs.Methods and results: Adipose tissue from nine donors was divided into two equal fractions. SVF was then isolated either mechanically or with collagenase, respectively. The resulting cells were analyzed for their surface markers directly after isolation and at passage five. Proliferation, tri-lineage differentiation, and secretome markers were measured after passage four.Using collagenase compared to mechanical isolation did not alter the expression of typical surface markers of ADSCs. ADSCs isolated with collagenase showed a significantly shorter population doubling time (p < 0.001), a significantly higher mean specific GPDH-activity, a stronger intensity in perilipin staining (p = 0.005), and a significantly higher extracellular calcium deposition (p = 0.006) than mechanically isolated ADSCs. The expression of adipogenic and osteogenic marker genes was not different in mechanically versus enzymatically isolated ADSCs. There were no significant differences in proteoglcyan production (p > 0.05) and the concentration of type 2 collagen. Except for an increased CCL2 concentration in mechanically isolated ASDCs (p = 0.01), there were no significant differences in the concentration of secreted proteins between both isolation methods. Conclusions: The use of collagenase does not substantially impair central in vitro characteristics and functions of human adipose tissue-derived stem cells.
