Accuracy study of Angiotensin 1-7 composite index test to predict pulmonary fibrosis and guide treatment.

BACKGROUND: Pulmonary fibrosis can develop after acute respiratory distress syndrome (ARDS). The hypothesis is we are able to measure phenotypes that lie at the origin of ARDS severity and fibrosis development. The aim is an accuracy study of prognostic circulating biomarkers. METHODS: A longitudinal study followed COVID-related ARDS patients with medical imaging, pulmonary function tests and biomarker analysis, generating 444 laboratory data. Comparison to controls used non-parametrical statistics; p < 0·05 was considered significant. Cut-offs were obtained through receiver operating curve. Contingency tables revealed predictive values. Odds ratio was calculated through logistic regression. RESULTS: Angiotensin 1-7 beneath 138 pg/mL defined Angiotensin imbalance phenotype. Hyper-inflammatory phenotype showed a composite index test above 34, based on high Angiotensin 1-7, C-Reactive Protein, Ferritin and Transforming Growth Factor-ß. Analytical study showed conformity to predefined goals. Clinical performance gave a positive predictive value of 95 % (95 % confidence interval, 82 %-99 %), and a negative predictive value of 100 % (95 % confidence interval, 65 %-100 %). Those severe ARDS phenotypes represented 34 (Odds 95 % confidence interval, 3-355) times higher risk for pulmonary fibrosis development (p < 0·001). CONCLUSIONS: Angiotensin 1-7 composite index is an early and objective predictor of ARDS evolving to pulmonary fibrosis. It may guide therapeutic decisions in targeted phenotypes.

Targeting RhoA expression with formononetin and salvianolic acid B to mitigate pancreatic cancer-associated endothelial cells changes.

ETHNOPHARMACOLOGICAL RELEVANCE: According to the theory of Qi and blood in Traditional Chinese Medicine (TCM), the combination of Qi-reinforcing herbs and blood-activating herbs has a synergistic effect in improving blood stasis syndrome, especially in tumor treatment. The classic "Radix Astragali - Salvia miltiorrhiza" duo exemplifies this principle, renowned for invigorating Qi and activating blood flow, employed widely in tumor therapies. Our prior research underscores the potent inhibition of pancreatic tumor xenografts by the combination of Formononetin (from Radix Astragali) and Salvianolic acid B (from Salvia miltiorrhiza) in vitro. However, it remains unclear whether this combination can inhibit the abnormal vascularization of pancreatic tumors to achieve its anti-cancer effect. AIM OF THE STUDY: Abnormal vasculature, known to facilitate tumor growth and metastasis. Strategies to normalize tumor-associated blood vessels provide a promising avenue for anti-tumor therapy. This study aimed to unravel the therapeutic potential of Formononetin combined with Salvianolic acid B (FcS) in modulating pancreatic cancer's impact on endothelial cells, illuminate the underlying mechanisms that govern this therapeutic interaction, thereby advancing strategies to normalize tumor vasculature and combat cancer progression. MATERIALS AND METHODS: A co-culture system involving Human Umbilical Vein Endothelial Cells (HUVECs) and PANC-1 cells was established to investigate the potential of targeting abnormal vasculature as a novel anti-tumor therapeutic strategy. We systematically compared HUVEC proliferation, migration, invasion, and lumenogenesis in both mono- and co-culture conditions with PANC-1 (H-P). Subsequently, FcS treatment of the H-P system was evaluated for its anti-angiogenic properties. Molecular docking was utilized to predict the interactions between Formononetin and Salvianolic acid B with RhoA, and the post-treatment expression of RhoA in HUVECs was assessed. Furthermore, we utilized shRhoA lentivirus to elucidate the role of RhoA in FcS-mediated effects on HUVECs. In vivo, a zebrafish xenograft tumor model was employed to assess FcS's anti-tumor potential, focusing on cancer cell proliferation, migration, apoptosis, and vascular development. RESULTS: FcS treatment demonstrated a significant, dose-dependent inhibition of PANC-1-induced alterations in HUVECs, including proliferation, migration, invasion, and tube formation capabilities. Molecular docking analyses indicated potential interactions between FcS and RhoA. Further, FcS treatment was found to downregulate RhoA expression and modulated the PI3K/AKT signaling pathway in PANC-1-induced HUVECs. Notably, the phenotypic inhibitory effects of FcS on HUVECs were attenuated by RhoA knockdown. In vivo zebrafish studies validated FcS's anti-tumor activity, inhibiting cancer cell proliferation, metastasis, and vascular sprouting, while promoting tumor cell apoptosis. CONCLUSIONS: This study underscores the promising potential of FcS in countering pancreatic cancer-induced endothelial alterations. FcS exhibits pronounced anti-abnormal vasculature effects, potentially achieved through downregulation of RhoA and inhibition of the PI3K/Akt signaling pathway, thereby presenting a novel therapeutic avenue for pancreatic cancer management.

Assessing the potential fasting and postprandial mechanisms involved in the acute hypoglycemic and anti-hyperglycemic effects of four selected plants from Iran used in traditional Persian medicine.

ETHNOPHARMACOLOGICAL RELEVANCE: In traditional Persian medicine (TPM), people often use herbal infusions as a dosage form to treat diseases related to hyperglycemia, known as 'dam-kardeh'. Traditionally, herbal preparations of Eryngium bungei Boiss. (E. b), Tragopogon buphthalmoides (DC.) Boiss. (T. b), Salvia hydrangea DC. ex Benth. (S. h), and Juniperus polycarpos K. Koch. (J. p) are used to manage diabetes in Iran. However, there is no evidence of their effectiveness in controlling glucose levels and their mechanisms remain unclear. AIM OF THE STUDY: This study aimed to investigate whether traditional doses of plant infusions can have hypoglycemic and/or anti-hyperglycemic effects during fasting and/or postprandial states and establish the basis for future research on their potential mechanisms of action. MATERIALS AND METHODS: The effects of traditional doses of herbal extracts on blood glucose levels in STZ-NA-induced hyperglycemic rats were investigated in 2-h acute tests during fasting and postprandial states (with a glucose load). In addition, the potential inhibitory effect in vitro of enzymes involved in relevant pathways, such as gluconeogenesis (fructose-1,6-bisphosphatase, FBPase and glucose-6-phosphatase, G6Pase), carbohydrate breakdown (intestinal α-glucosidases), and insulin sensitivity (protein tyrosine phosphatase 1B, PTP-1B) was evaluated. Acute toxicity tests were carried out and HPLC-SQ-TOF was used to analyze the chemical profiles of the plant extracts. RESULTS: In the fasting state, T. b, S. h, and E. b were as effective as glibenclamide in lowering blood glucose levels in hyperglycemic rats. Moreover, all three suppressed G6Pase and FBPase enzymatic activity by 90-97% and 80-91%, respectively. On the other hand, significant postprandial hypoglycemic efficacy was observed for E. b, S. h, and T. b. Based on the AUC values, T. b caused a reduction comparable to the therapeutic efficacy of repaglinide. When investigating the possible mechanisms of action involved in this activity, E. b, S. h, and T. b showed significant inhibition of PTP-1B in vitro (>70%). Finally, all plant extracts showed no signs of acute toxicity. Several compounds that may contribute to biological activities were identified, including phenolic acids and flavonoid glycosides. CONCLUSIONS: The present study supports the traditional use of T. b, E. b and S. h for the control of diabetes in the fasting and postprandial state. Moreover, these plants were found to be rich in bioactive compounds with hypoglycemic and antihyperglycemic activities. On the other hand, J. p, showed a modest effect only in the fasting state and after 90 min. Further studies are needed to expand these results by analyzing the chemical composition and using complementary experimental models.

Cu,Ce-containing phosphotungstates as laccase-like nanozyme for colorimetric detection of Cr(VI) and Fe(â ¢).

Herein, a nanocomposite of Cu,Ce-containing phosphotungstates (Cu,Ce-PTs) with outstanding laccase-like activity was fabricated via a one-pot microwave-assisted hydrothermal method. Notably, it was discovered that both Fe3+ and Cr6+ could significantly enhance the electron transfer rates of Ce3+ and Ce4+, along with generous Cu2+ with high catalytic activity, thereby promoting the laccase-like activity of Cu,Ce-PTs. The proposed system can be used for the detection of Fe3+ and Cr6+ in a range of 0.667-333.33 µg/mL and 0.033-33.33 µg/mL with a low detection limit of 0.135 µg/mL and 0.0288 µg/mL, respectively. The proposed assay exhibits excellent reusability and selectivity and can be used in traditional Chinese medicine samples analysis.

Sex-specific Prediction of Cardiogenic Shock After Acute Coronary Syndromes: The SEX-SHOCK Score.

BACKGROUND: and aims: Cardiogenic shock (CS) remains the primary cause of in-hospital death after acute coronary syndromes (ACS), with its plateauing mortality rates approaching 50%. To test novel interventions, personalized risk prediction is essential. The ORBI (Observatoire Régional Breton sur l'Infarctus) score represents the first-of-its-kind risk score to predict in-hospital CS in ACS patients undergoing percutaneous coronary intervention (PCI). However, its sex-specific performance remains unknown, and refined risk prediction strategies are warranted. METHODS: This multinational study included a total of 53 537 ACS patients without CS on admission undergoing PCI. Following sex-specific evaluation of ORBI, regression and machine-learning models were used for variable selection and risk prediction. By combining best-performing models with highest-ranked predictors, SEX-SHOCK was developed, and internally and externally validated. RESULTS: The ORBI score showed lower discriminative performance for the prediction of CS in females than males in Swiss (AUC [95% CI]: 0.78 [0.76-0.81] vs. 0.81 [0.79-0.83]; p=0.048) and French ACS patients (0.77 [0.74-0.81] vs. 0.84 [0.81-0.86]; p=0.002). The newly developed SEX-SHOCK score, now incorporating ST-segment elevation, creatinine, C-reactive protein, and left ventricular ejection fraction, outperformed ORBI in both sexes (females: 0.81 [0.78-0.83]; males: 0.83 [0.82-0.85]; p<0.001), which prevailed following internal and external validation in RICO (females: 0.82 [0.79-0.85]; males: 0.88 [0.86-0.89]; p<0.001) and SPUM-ACS (females: 0.83 [0.77-0.90], p=0.004; males: 0.83 [0.80-0.87], p=0.001). CONCLUSIONS: The ORBI score showed modest sex-specific performance. The novel SEX-SHOCK score provides superior performance in females and males across the entire spectrum of ACS, thus providing a basis for future interventional trials and contemporary ACS management.

Examining Food Security, Fruit and Vegetable Intake, and Cardiovascular Disease Risk Outcomes of Produce Prescription (PPR) Programs: A Systematic Review.

OBJECTIVE: Outcomes from produce prescription (PPR) programs, an exemplar of a Food is Medicine intervention, have not been synthesized. The objective of this study was to conduct a systematic review to examine the impact of PPR programs on food security, fruit and vegetable (FV) intake, and/or cardiovascular risk factors (HbA1c, blood pressure, and blood lipids). DESIGN: Searches were conducted across three databases (PubMed, CINAHL, and Web of Science). Eligible studies were published between August 2012 and April 2023, conducted in the US in child/family, or adult populations, written in English and had a PPR program as an exposure. OUTCOMES VARIABLES MEASURED: Food security, FV intake, and/or cardiovascular risk factors. RESULTS: Twenty studies ranging from a duration of between 6 weeks to 24 months were included. Of the 5 studies (3 in child/family and 4 in adult populations) that analyzed changes in food security status, all reported significant (P < 0.05) improvements after the PPR program. Approximately half of the included studies found significant (P < 0.05) increases in fruit, vegetable, and/or FV intake. Only studies in adult populations included cardiovascular risk factor outcomes. In these studies, mixed findings were reported; however, there were significant (P < 0.05) improvements in HbA1c when PPR programs enrolled individuals with type 2 diabetes. CONCLUSIONS AND IMPLICATIONS: PPR programs provide an opportunity to improve food security in child/family, and adult populations. Evidence to support whether PPR programs increase FV intake and improve cardiovascular disease risk factors outside of HbA1c in adult populations with high HbA1c upon enrollment is less known.

How Do Nurses Experience Relational Work in the Emergency Department-Qualitative Study.

INTRODUCTION: This study aimed to explore how nurses experience relational work in the emergency department. METHODS: A qualitative design with 34 focus group interviews using an abductive thematic analysis were completed for this study. Participants were recruited from an annual mandatory continuous learning program in 2020-2022 at 2 university hospitals in the Capital Region of Denmark. We applied semistructured interviews in an instructor-supported reflection session on the topic "relational nursing care." Group discussion was supported by an interview guide addressing key elements of the nurse-patient relationship as described in the fundamentals of care framework. RESULTS: Acute care nurses' attention was primarily directed toward the initial patient assessment, rather than toward the later stages of the patient trajectory. Forming a relationship with the patient was highly individual and done at the discretion of each nurse. The key elements of relational nursing were not mutually exclusive, but the findings could be separated into biomedical and relational care, where biomedical tasks took precedence. DISCUSSION: Relational care in the emergency department is optional and individually performed. Moreover, emergency nurses lack a vocabulary to express this type of work. Consequently, there is a risk that patients' psychosocial needs are not sufficiently met. According to the emergency nurses participating in this study, nurses fall short when performing and describing relational care. Nurses need more knowledge to address the psychosocial patient needs during short-term hospital admissions. Relational care and patient centeredness also need to be acknowledged by nursing leaders and further developed.

Efficacy and safety of Kegan Liyan oral liquid for patients with acute pharyngitis: A randomized, double-blinded, placebo-controlled, multi-center trial.

BACKGROUND: Alleviating the sore throat caused by acute pharyngitis is a primary patient concern. However, antibiotics are not commonly recommended drugs, and abuse can lead to serious consequences such as drug resistance. Therefore, seeking alternative treatments is necessary. PURPOSE: To investigate the efficacy and safety of Kegan Liyan (KGLY) oral liquid for patients with acute pharyngitis. STUDY DESIGN: Randomized, double-blinded, placebo-controlled, multi-center study. METHODS: Participants from 17 hospitals were randomly assigned 1:1 to receive KGLY oral liquid or placebo for five days. Assessments occurred at baseline, day 3, and day 6. The primary outcome was the recovery rate. Secondary outcomes included sore throat and cough visual analogue scale (VAS), the area under the curve (AUC) of sore throat VAS, time to sore throat relief and recovery, proportion of participants with sore throat relief and recovery, traditional Chinese medicine (TCM) syndrome score, single TCM manifestation score and use of acetaminophen. RESULTS: Involving 239 participants (120 in KGLY and 119 in placebo group), the study found a significantly higher recovery rate on day 6 in the KGLY group (between-group difference, 27.20 % [15.00 % to 39.40 %], p < 0.001). On day 3 and 6, the KGLY group showed significantly larger reductions in sore throat (-3.02 vs -2.37, p = 0.001; -4.66 vs -3.64, p < 0.001) and cough VAS scores (-1.55 vs -1.05, p = 0.004; -2.28 vs -1.56, p < 0.001) from baseline. KGLY oral liquid lowered the AUC of sore throat VAS score (-2.33 [-4.10 to -0.56], p = 0.011), shortened time to sore throat recovery (hazard ratio, 0.42 [0.30 to 0.59], p < 0.001), increased sore throat recovery rate at day 6 (75.00 % vs 42.86 %, p < 0.001), decreased the TCM syndrome score (-2.03 [-2.69 to -1.37], p < 0.001), and improved individual TCM symptoms compared to placebo. No significant differences between the groups in acetaminophen usage. KGLY oral liquid was safe and tolerated. CONCLUSION: KGLY oral liquid may be a beneficial and safe alternative treatment for acute pharyngitis, which can alleviate symptoms such as sore throat, swollen throat, cough, and phlegm production.

Demographics and Characteristics of Vice Chairs in Academic Orthopaedic Surgery Programs: A Descriptive Study.

INTRODUCTION: The Vice-chair (VC) position is gaining popularity in academic orthopaedic surgery departments; however, there is a paucity of information regarding qualifications and career advancements associated with this role. The purpose of this study was to define the characteristics of current orthopaedic surgery department VCs. DESIGN: Descriptive study following a retrospective web-based search utilizing the Fellowship and Residency Electronic Interactive Database (FREIDA) database and orthopaedic surgery residency program websites. SETTING: 200 ACGME-accredited orthopaedic surgery residency programs across the United States. PARTICIPANTS: Program name and hospital affiliations were collected from the FREIDA database to account for all ACGME-accredited programs. The following information was derived from publicly available program websites: title, role description, previously trained institutions, academic rank, and concurrent roles of VCs. Research productivity was measured using the H-index. The previous roles of current Department Chairs (DC) were also evaluated. RESULTS: Of the 178 VCs identified, VC of Research (n = 36; 20%), Education (n = 25; 14%), and Clinical Operations/Affairs (n = 21; 12%) were the most common titles. Women made up 17% (n = 30) of the VCs. Trauma (n = 36; 20%) was the most common fellowship subspecialty among VCs. The average H-index for VCs was 25. Among VCs, 94 (53%) were professors, 78 were also Chiefs/Heads/Directors (44%), 7 (4%) were Fellowship Directors, and 18 (10%) were Residency Directors. Twenty-six of 95 (27%) current DC had VC experience. CONCLUSION: The findings can facilitate effective leadership development, promotion of diversity and inclusion in these roles, and guidance for those who seek such leadership positions.

Development and evaluation of a TaqMan® real-time PCR assay for species-specific detection of Ehrlichia canis.

The aim of this work was to develop a real-time PCR assay with a TaqMan® probe that detects a species-specific part of the 16S rDNA gene of Ehrlichia canis. Canine blood samples (n = 207), collected and tested by a conventional PCR assay within a study conducted by De Salvo et al., were simultaneously analyzed with the novel designed real-time PCR, and the results of both assays were compared. The agreement between the two methods was 97.6 % with a kappa value of 0.92186. Hereby, the standard error was 0.034416 and the 95 % confidence interval from 0.8544 to 0.98931. While the conventional PCR assay showed false negative results (2.42 %; 5/207), the real-time PCR assays showed a specificity of 100 %. The results of the current study showed that the developed assay presents sensitivity and specificity for the detection of E. canis in blood samples, adding a new tool for the diagnosis of this pathogen.

An integrative pediatric oncology program addressing parents' quality of life-related concerns.

CONTEXT AND OBJECTIVES: Parents of children with cancer face bio-psycho-social-spiritual concerns which can significantly reduce quality of life (QoL). We examined the impact of an integrative oncology (IO) intervention on QoL-related concerns among parents of children in a pediatric hematology-oncology department. METHODS: The study was prospective, controlled, non-randomized and patient-preferenced. Parents of children recently (≤ 6 weeks) diagnosed with cancer were assessed using the Measure Yourself Concerns and Wellbeing (MYCaW), Edmonton Symptom Assessment Scale (ESAS) and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). An IO consultation was provided, with training in daily relaxation-breathing and manual treatments, and guidance on herbal medicine. Parents in both groups were re-assessed after three weeks. RESULTS: Of 68 parents consenting to participate, 37 (54%) underwent the intervention with 31 serving as controls. Multivariate analysis found the IO intervention group to contain more Hebrew-speakers (OR=5.96, 95% CI=1.3-27.3, P=0.022); females (OR=5.23, 95% CI=1.1-24.8, P=0.038); and report pain (OR=1.2, 95% CI=1.0-1.4, p=0.045) and impaired appetite on ESAS (OR=1.23, 95% CI=1.01-1.48, p=0.034) when compared to controls. Only the intervention group showed increased baseline-to-3-week scores for physical functioning (p<0.001), cognitive functioning (0=0.018) and fatigue on EORTC (p<0.001); and for ESAS appetite (p<0.001) and anxiety (p=0.02). ESAS sleep increased only in controls (p=0.029). CONCLUSION: IO interventions in pediatric hematology-oncology addressing QoL-related concerns among parents are feasible, potentially increasing predominantly physical symptoms and functioning. Further research is needed to confirm these "real-world" clinical outcomes, and the role of IO in "Caring for the Caregiver".

Employing Magnetic Resonance Histology for Precision Chronic Limb-Threatening Ischemia Treatment Planning.

OBJECTIVE: Recent randomized controlled trials have demonstrated a notable prevalence of immediate technical failures (ITFs) in percutaneous vascular interventions (PVIs) for complex arterial lesions associated with chronic limb-threatening ischemia (CLTI). Current imaging modalities present inherent limitations in identifying these lesions, making it challenging to determine the most suitable candidates for PVI. We present a novel preprocedural magnetic resonance imaging (MRI) histology protocol for identifying lesions that might present a higher rate of immediate and mid-term PVI failure. METHODS: 22 patients (13 females, average age 65.8±9.72 years) scheduled for PVI were prospectively enrolled and underwent 3T MRI using ultrashort echo time and 'Steady-State Free Precession' contrasts to characterize target lesions prior to PVI. Lesions were scored as 'hard' if >50% of the lumen was occluded by hard components (calcium/dense collagen) on MRI in the hardest cross-section. Two readers evaluated MRI datasets. TASC/GLASS/WIFi scoring was performed based on intraprocedural angiograms and chart review. The relationship between MRI scoring, TASC/GLASS scoring and procedural outcomes was investigated using univariate analysis. Mid-term follow-up (revascularization and amputation rate) was recorded at 3 months and 6 months, post-intervention. RESULTS: Our cohort of 22 patients yielded 40 target lesions. 5 lesions were excluded (2 non-diagnostic image quality, 3 PVIs were ultimately diagnostic only). 6 lesions (17%) were scored as 'hard'. MRI-scored 'hard' lesions had higher proportion of ITF ('hard' vs 'soft' 83% (n/N=5/6) vs. 3% (n/N=1/29), p<.001). 'Hard' versus 'soft' MRI scoring was the only factor significantly associated with immediate PVI technical success (p < .001), as opposed to TASC/GLASS scoring. Both at 3 months and 6 months after PVI, the re-intervention rate was significantly higher among those lesions which were scored 'hard' on MRI (3-month: hard: 80% vs. soft: 16%, p =.011 6-month: hard: 80%, soft: 27%, p=.047). CONCLUSIONS: MRI histology could be a valuable tool for optimizing PVI patient selection and treatment strategies.

Stakeholder-informed positivity thresholds for disease markers and risk scores: a methodological framework and an application in obstructive lung disease.

OBJECTIVE: A positivity threshold is often applied to markers or predicted risks to guide disease management. These rules are often decided exclusively by clinical experts despite being sensitive to the preferences of patients and general public as ultimate stakeholders. STUDY DESIGN AND SETTING: We propose an analytical framework for quantifying the net benefit of an evidence-based positivity threshold based on combining preference-sensitive (e.g., how individuals weight benefits and harms of treatment) and preference-agnostic (e.g., the magnitude of benefit and the risk of harm) parameters. We propose parsimonious choice experiments to elicit preference-sensitive parameters from stakeholders, and evidence synthesis to quantify the value of preference-agnostic parameters. We apply this framework to maintenance azithromycin therapy for chronic obstructive pulmonary disease (COPD) using a discrete choice experiment (DCE) to estimate preference weights for attribute level associated with treatment. We identify the positivity threshold on 12-month moderate or severe exacerbation risk that would maximize the net benefit of treatment in terms of severe exacerbations avoided. RESULTS: In the case study, the prevention of moderate and severe exacerbations (benefits) and the risk of hearing loss and gastrointestinal symptoms (harms) emerged as important attributes. 477 respondents completed the DCE survey. Relative to each percent risk of severe exacerbation, preference weights for each percent risk of moderate exacerbation, hearing loss, and gastrointestinal symptoms were 0.395 (95%CI 0.338-0.456), 1.180 (95%CI 1.071-1.201) and 0.253 (95%CI 0.207-0.299), respectively. The optimal threshold that maximized net benefit was to treat patients with a 12-month risk of moderate or severe exacerbations ≥12%. CONCLUSION: The proposed methodology can be applied to many contexts where the objective is to devise positivity thresholds that need to incorporate stakeholder preferences. Applying this framework to COPD pharmacotherapy resulted in a stakeholder-informed treatment threshold that was substantially lower than the implicit thresholds in contemporary guidelines.

Workforce Diversity and Equity Among Critical Care Physicians.

Health disparities persist among minoritized populations. A diverse clinician workforce may help address these disparities and improve patient outcomes; however, diversity in the critical are workforce (particularly among women and those historically underrepresented in medicine (URiM)) is lacking. This review describes factors contributing to low respresentation of women and URiM in critical care medicine, and proposes strategies to overcome those barriers.

The Conundrum of Mechanics Versus Genetics in Congenital Hydrocephalus and Its Implications for Fetal Therapy Approaches: A Scoping Review.

Recent advances in gene therapy, particularly for single-gene disorders (SGDs), have led to significant progress in developing innovative precision medicine approaches that hold promise for treating conditions such as primary hydrocephalus (CH), which is characterized by increased cerebrospinal fluid (CSF) volumes and cerebral ventricular dilation as a result of impaired brain development, often due to genetic causes. CH is a significant contributor to childhood morbidity and mortality and a driver of healthcare costs. In many cases, prenatal ultrasound can readily identify ventriculomegaly as early as 14-20 weeks of gestation, with severe cases showing poor neurodevelopmental outcomes. Postnatal surgical approaches, such as ventriculoperitoneal shunts, do not address the underlying genetic causes, have high complication rates, and result in a marginal improvement of neurocognitive deficits. Prenatal somatic cell gene therapy (PSCGT) promises a novel approach to conditions such as CH by targeting genetic mutations in utero, potentially improving long-term outcomes. To better understand the pathophysiology, genetic basis, and molecular pathomechanisms of CH, we conducted a scoping review of the literature that identified over 160 published genes linked to CH. Mutations in L1CAM, TRIM71, MPDZ, and CCDC88C play a critical role in neural stem cell development, subventricular zone architecture, and the maintenance of the neural stem cell niche, driving the development of CH. Early prenatal interventions targeting these genes could curb the development of the expected CH phenotype, improve neurodevelopmental outcomes, and possibly limit the need for surgical approaches. However, further research is needed to establish robust genotype-phenotype correlations and develop safe and effective PSCGT strategies for CH.

Lectin-glycan interactions: a comprehensive cataloguing of cancer-associated glycans for biorecognition and bio-alteration: a review.

This comprehensive review meticulously compiles data on an array of lectins and their interactions with different cancer types through specific glycans. Crucially, it establishes the link between aberrant glycosylation and cancer types. This repository of lectin-defined glycan signatures, assumes paramount importance in the realm of cancer and its dynamic nature. Cancer, known for its remarkable heterogeneity and individualized behaviour, can be better understood through these glycan signatures. The current review discusses the important lectins and their carbohydrate specificities, especially recognizing glycans of cancer origin. The review also addresses the key aspects of differentially expressed glycans on normal and cancerous cell surfaces. Specific cancer types highlighted in this review include breast cancer, colon cancer, glioblastoma, cervical cancer, lung cancer, liver cancer, and leukaemia. The glycan profiles unveiled through this review hold the key to tailor-made treatment and precise diagnostics. It opens up avenues to explore the potential of targeting glycosyltransferases and glycosidases linked with cancer advancement and metastasis. Armed with knowledge about specific glycan expressions, researchers can design targeted therapies to modulate glycan profiles, potentially hampering the advance of this relentless disease.

11. Cervicogenic headache and occipital neuralgia.

INTRODUCTION: Cervicogenic headache (CEH) and occipital neuralgia (ON) are headaches originating in the occiput and that radiate to the vertex. Because of the intimate relationship between structures based in the occiput and those in the upper cervical region, there is significant overlap between the presentation of CEH and ON. Diagnosis starts with a headache history to assess for diagnostic criteria formulated by the International Headache Society. Physical examination evaluates range of motion of the neck and the presence of tender areas or pressure points. METHODS: The literature for the diagnosis and treatment of CEH and ON was searched from 2015 through August 2022, retrieved, and summarized. RESULTS: Conservative treatment includes pain education and self-care, analgesic medication, physical therapy (such as reducing secondary muscle tension and improving posture), the use of TENS (transcutaneous electrical nerve stimulation), or a combination of the aforementioned treatments. Injection at various anatomical locations with local anesthetic with or without corticosteroids can provide pain relief for a short period. Deep cervical plexus block can result in improved pain for less than 6 months. In both CEH and ON, an occipital nerve block can provide important diagnostic information and improve pain in some patients, with PRF providing greater long-term pain control. Radiofrequency ablation of the cervical facet joints can result in improvement for over 1 year. Occipital nerve stimulation (ONS) should be considered for the treatment of refractory ON. CONCLUSION: The treatment of CEH preferentially consists of radiofrequency treatment of the facet joints, while for ON, pulsed radiofrequency of the occipital nerves is indicated. For refractory cases, ONS may be considered.

Multidisciplinary approaches to study anaemia with special mention on aplastic anaemia (Review).

Anaemia is a common health problem worldwide that disproportionately affects vulnerable groups, such as children and expectant mothers. It has a variety of underlying causes, some of which are genetic. A comprehensive strategy combining physical examination, laboratory testing (for example, a complete blood count), and molecular tools for accurate identification is required for diagnosis. With nearly 400 varieties of anaemia, accurate diagnosis remains a challenging task. Red blood cell abnormalities are largely caused by genetic factors, which means that a thorough understanding requires interpretation at the molecular level. As a result, precision medicine has become a key paradigm, utilising artificial intelligence (AI) techniques, such as deep learning and machine learning, to improve prognostic evaluation, treatment prediction, and diagnostic accuracy. Furthermore, exploring the immunomodulatory role of vitamin D along with biomarker­based molecular techniques offers promising avenues for insight into anaemia's pathophysiology. The intricacy of aplastic anaemia makes it particularly noteworthy as a topic deserving of concentrated molecular research. Given the complexity of anaemia, an integrated strategy integrating clinical, laboratory, molecular, and AI techniques shows a great deal of promise. Such an approach holds promise for enhancing global anaemia management options in addition to advancing our understanding of the illness.
