Soluble Endoglin and Syndecan-1 levels predicts the clinical outcome in COVID-19 patients. Microb Pathog 2024; 188:106558. [PMID: 38272329 DOI: 10.1016/j.micpath.2024.106558] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Revised: 01/21/2024] [Accepted: 01/22/2024] [Indexed: 01/27/2024]
Abstract
Endothelial instability is reported to be involved in the pathogenesis of COVID-19. The mechanism that regulates the endothelial dysfunction and disease virulence is not known. Studies on proteins that are released into circulation by activated endothelial cells may provide some means to understand the disease manifestation. The study investigated the circulating levels of two molecules Endoglin (Eng) and Syndecan-1 (SDC-1) that are presumed to be involved in the maintenance of endothelial integrity and their association with hypercoagulation marker in COVID-19 patients. The serum levels of Eng, SDC-1, D-mer were evaluated using ELISA at the time of admission (DOA) and day 7 post-admission among COVID-19 patients (N = 39 with 17 moderate and 22 severe cases). Compared to the time of admission, there was an increase in sEng and sSDC1 levels in all COVID-19 cases on day 7 post admission. The serum levels of sEng and sSDC-1 was significantly (P ≤ 0.001 & P ≤ 0.01 respectively) elevated in severe cases including the four deceased group compared to moderate cases on day 7 post admission. Further, the study molecules showed a strong positive association (P ≤ 0.001) with the hypercoagulation marker D-mer. The results show an early shedding of the endothelial proteins sEng and sSDC-1 into circulation as a host response to the viral infection during the febrile phase of infection. Increased levels of sEng and sSDC-1 along with D-mer could be beneficial in predicting COVID-19 disease severity.

Abstract
The increased detection of thyroid nodules in the human population has led to an increase in the number of thyroid surgeries without an improvement in survival outcomes. Though the choice for surgery is straightforward in malignant thyroid nodules, the decision is far more complex in those nodules that get categorized into indeterminate thyroid nodules (ITN) by fine needle aspiration. Therefore, there is a pressing need to develop a tool that will aid in decision-making among the ITN. In this context, the development of various molecular testing (MT) panels has helped to confirm or rule out malignancy, reducing unnecessary surgeries and potentially guiding the extent of surgery as well. Currently, such tests are widely used among the Western population but these MT panels are not used by the South Asian population because of non-availability of validated panels and the high cost involved. There is a need to develop a suitable panel which is population-specific and validate the same. In this review, we would focus on current trends in the management of ITN among the South Asian population and how to develop a novel MT panel which is cost-effective, with high diagnostic accuracy obviating the need for expensive panels that already exist.

Abstract
Delayed hyponatraemia(DH) is a common complication following trans-sphenoidal surgery(TSS) for pituitary tumour. We evaluated the prevalence of DH following TSS, and assessed the factors associated with DH, including early post-operative diabetes insipidus(EPDI). This retrospective study included 100 TSS for pituitary tumours in 98 patients, over a period of 26 months. Subjects were divided into two groups: those who developed hyponatraemia and those who did not develop hyponatraemia, during post-operative days 4 to 14. The clinical characteristics and peri-operative parameters were compared between the two groups, to identify factors predicting DH. The mean age of the patients was 42.0±13.6 years, 58 (59%) were females and 61 (61%) had functional tumours. Thirty-six patients(36%) developed DH following TSS of whom majority(58%) were diagnosed on post-operative days 7 and 8; only 8/36 (22%) were symptomatic. Syndrome of inappropriate antidiuretic hormone secretion(SIADH) was found to be the most common aetiology of DH. On logistic regression analysis, intra-operative cerebrospinal fluid(CSF) leak (OR 5.0; 95% CI 1.9-13.8; p=0.002), EPDI (OR 3.4; 95% CI 1.3-9.2; p=0.015) and peri-operative steroid use (OR 3.6; 95% CI 1.3-9.8; p=0.014) were found to be significantly associated with DH. In conclusion, EPDI, intra-operative CSF leak and peri-operative steroid use were significant predictors of DH. EPDI predicts moderate to severe hyponatraemia with 80% specificity but has low sensitivity(47%). As most patients have asymptomatic hyponatraemia, serum sodium measurement on POD 7 to 10 would be helpful to identify DH in patients at increased risk.

Background
Meditation can induce changes in autonomic balance, which can benefit cardiovascular health. The present meta-analysis evaluated changes in heart rate variability (HRV) in meditators.
Methods
PubMed and Embase were searched for primary prospective studies using the search terms ‘heart rate variability’ and ‘meditation’ until January 18th, 2019. The statistical significance of the difference between subgroups is evaluated by the standardized mean difference (SMD), 95% confidence interval (CI), and P-value. I2 value was used to assess the statistical heterogeneity between the included studies.
Results
Twenty-one studies involving 538 meditators (experienced= 209, beginners= 329) and 334 controls (mean age= 40.61, 35% male) were included. Regarding time-domain indices, no statistically significant differences were observed when assessing HRV between i) meditators versus controls (SMD= -0.17; 95% CI: [-0.50, 0.17]; p= 0.30; I2= 0%), ii) pre- versus post-meditation (SMD= -0.41; 95% CI: [-1.10, 0.28]; p= 0.25; I2= 80%) or iii) at baseline versus during meditation (SMD= -0.40; 95% CI: [-0.94, 0.14]; p= 0.14; I2= 72%). Pertaining to frequency-domain indices, analysis of low frequency (LF), normalized low frequency (LFnu) and high frequency (HF) between i) meditators versus controls, ii) at baseline versus post-meditation and iii) at baseline versus during meditation yet again did not show any variations. Seven studies assessed normalized high frequency (HFnu) at baseline versus during meditation collectively demonstrated a significantly higher HFnu during meditation in beginners with notable heterogeneity (SMD= 1.29; 95% CI: [0.09, 2.49]; p= 0.04; I2= 95). Moreover, LF/HF was evaluated by seven studies at baseline versus during meditation. Both meta-analysis (SMD= 0.76; 95% CI: [-0.17, 1.69]; p= 0.11; I2= 94%) as well as subset analysis of experienced meditators (SMD= -0.46; 95% CI: [-0.88, -0.03]; p= 0.03; I2= 0%) revealed a significantly lower LF/HF at baseline.
Conclusions
Short-term changes in HRV indices were observed during meditation, but there is limited evidence for significant long-term effects.

Abstract
Recent studies have shown the involvement of GluN2A subunit-containing NMDA receptors in various neurological and pathological disorders. In the X-ray crystal structure, TCN-201 (1) and analogous pyrazine derivatives 2 and 3 adopt a U-shape (hairpin) conformation within the binding site formed by the ligand binding domains of the GluN1 and GluN2A subunits. In order to mimic the resulting π/π-interactions of two aromatic rings in the binding site, a [2.2]paracyclophane system was designed to lock these aromatic rings in a parallel orientation. Acylation of [2.2]paracyclophane (5) with oxalyl chloride and chloroacetyl chloride and subsequent transformations led to the oxalamide 7, triazole 10 and benzamides 12. The GluN2A inhibitory activities of the paracyclophane derivatives were tested with two-electrode voltage clamp electrophysiology using Xenopus laevis oocytes expressing selectively functional NMDA receptors with GluN2A subunit. The o-iodobenzamide 12 b with the highest similarity to TCN-201 showed the highest GuN2A inhibitory activity of this series of compounds. At a concentration of 10 μM, 12 b reached 36 % of the inhibitory activity of TCN-201 (1). This result indicates that the [2.2]paracyclophane system is well accepted by the TCN-201 binding site.

Abstract
Objective The treatment of Camurati-Engelmann disease (CED) involves the use of glucocorticoids, analgesics, and bisphosphonates; experience with the use of losartan is limited. Our objective was to describe the case of a patient diagnosed with CED whose symptoms remained refractory while on steroids and bisphosphonates and who was successfully treated with losartan. Case Report A 27-year-old woman presented with bone pain involving her extremities and large joints for 1 year. Clinical examination revealed bone tenderness and proximal myopathy with elevated C-terminal peptide of type 1 collagen (1617 pg/mL; normal range, 137-573 pg/mL) and N-terminal propeptide of type 1 procollagen levels (163 ng/mL; normal range, 5.1-58.3 ng/mL). Calcium (9.4 mg/dL; normal range, 8.3-10.4 mg/dL), phosphate (3.4 mg/dL; normal range, 2.5-4.5 mg/dL), and parathyroid hormone (62 pg/mL; normal range, 8-80 pg/mL) levels were within the normal range. Radiographs showed hyperostosis involving the diaphyseal region of long bones of the lower and upper limbs, and a provisional diagnosis of CED was made. She was treated with prednisolone, 30 mg daily, with which she reported some improvement. As exogenous Cushing syndrome had developed in her because of prednisolone, its dose was tapered. Subsequently, her bone pain worsened. Thereafter, she was initiated on oral alendronate. Due to persistent pain, losartan was added, after which she had marked decrease in bone pain with a reduction in the C-terminal peptide of type 1 collagen (375 pg/mL) and N-terminal propeptide of type 1 procollagen (50 ng/mL) levels. Discussion Occasionally, CED presents therapeutic challenges, and when its symptoms remain refractory to conventional doses of steroids and bisphosphonates, other options may be needed. The abovementioned patient was initiated on losartan, which acts by downregulation of transforming growth factor β1, leading to the reduction in pain. Conclusion Losartan downregulates transforming growth factor β1 and may be offered as a steroid-sparing option in individuals diagnosed with CED if symptoms remain refractory to conventional treatment.

Abstract
Objective Primary hyperparathyroidism (PHPT) has varied clinical presentations. Hematologic abnormalities secondary to PHPT have been described before. However, pancytopenia as the initial presentation has rarely been reported. We report a patient with PHPT who presented for evaluation of pancytopenia. Methods Histopathology of the bone marrow at presentation is described. Bone biochemistry results and the hematologic profile before and after curative parathyroidectomy are presented. Results A 48-year-old woman presented with pancytopenia (hemoglobin, 6.3 g/dL; total leucocyte count, 3000 cells/mm3; and platelet count, 60 000 cells/mm3), and her bone marrow study showed marrow fibrosis. Biochemical evaluation revealed hypercalcemia (15.5 mg/dL), hypophosphatemia (2.2 mg/dL), and elevated total alkaline phosphatase (4132 U/L). Bone mineral density assessment by dual-energy X-ray absorptiometry scan revealed osteoporosis at all 3 sites, which was more severe in the distal one third of the forearm. Further investigations confirmed the diagnosis of PHPT (serum parathyroid hormone, 2082 pg/mL). Following curative parathyroidectomy, in addition to normalization of calcium, there was restoration of all 3 hematologic cell lines at 3 months. Conclusion Pancytopenia may be a rare manifestation of PHPT. Thus, it may be prudent to evaluate the calcium profile in patients with chronic refractory anemia and pancytopenia.

Abstract
Idiopathic systemic capillary leak syndrome (ISCLS) is a potentially fatal disorder characterised by 'attacks' of varying intensity of hypovolemic shock in association with haemoconcentration and hypoalbuminaemia. It is a disease of exclusion, and the severity of attacks may mimic sepsis at presentation. We report a case of a lady with recurrent attacks of ISCLS with at least two life-threatening episodes, having been treated elsewhere as a case of steroid insufficiency. The diagnosis is often challenging, and treatment of an acute episode involves the judicious use of fluids and vasopressors, as required. Prophylaxis to prevent further attacks is of varied success.

Abstract
Glutamatergic N-Methyl-d-aspartate (NMDA) receptors are heterotetrameric ion channels that can be comprised of different subunits. GluN2A subunit-containing NMDA receptors are associated with diseases like anxiety, depression, and schizophrenia. However, the exact contribution of these NMDA receptor subtypes is still unclear. To understand better the role of the GluN2A-containing receptors, novel ligands were designed. In co-crystallization with the isolated binding site, TCN-201 (1) and analogs adopt a U-shape conformation with parallel orientation of rings A and B. In order to increase the π/π-interactions between these rings, ring B of TCN-201 was replaced bioisosterically by different electron-rich thiazole, oxazole, and isoxazole heterocycles. The inhibitory activity was measured by two-electrode voltage clamp experiments with Xenopus laevis oocytes expressing GluN2A-containing NMDA receptors. It was found that 21c, 31a, 37a, and 37b were able to inhibit the ion channel. The isoxazole derivative 37b was the most potent negative allosteric modulator displaying 40% of the TCN-201 activity at a concentration of 10 μM.

Abstract
UNLABELLED This study from southern India showed that FRAX® with or without BMD or TBS predicted fragility vertebral fractures at a cut-off of ≥ 9% for major osteoporotic fracture and ≥ 2.5% for hip fracture with sensitivities of 77-88% and specificities of 55-72%. PURPOSE There is limited information available with regard to utility of Fracture Risk Assessment Tool (FRAX® tool) in predicting fragility fractures in Indian postmenopausal women. We studied the performance of 3 categories: FRAX® (without BMD), FRAX® (with BMD), and FRAX® (with BMD and TBS) in predicting fragility vertebral fractures in rural postmenopausal women. MATERIAL AND METHODS It was a cross-sectional study conducted at a south Indian tertiary care center. Rural postmenopausal women (n = 301) were recruited by simple random sampling. The risk for major osteoporotic fracture (MOF) and hip fracture (HF) was calculated individually for the 3 categories. The BMD (at lumbar spine and femoral neck) and vertebral fractures were assessed by a DXA (dual energy X-ray absorptiometry) scanner and TBS by TBS iNsight software. ROC curves were constructed, and area under curve (AUC), sensitivity and specificity of FRAX® scores, which would best predict prevalent vertebral fractures (moderate to severe), was computed. RESULTS The mean (SD) age was 65.6(5.1) years. The prevalence of osteoporosis at spine was 45%, and femoral neck was 32.6%. Moderate to severe vertebral fractures was seen in 29.2% of subjects. The performance of all 3 categories for FRAX® (MOF) and FRAX® (HF) were good (AUC was 0.798, 0.806, and 0.800, respectively, for MOF) at a cut-off score of ≥ 9, and at a cut-off of ≥ 2.5 for HF, it was 0.818, 0.775, and 0.770, respectively. At these cut-offs, sensitivities were 77-89%, and specificities were 55-72% for predicting prevalent vertebral fractures. CONCLUSION All three categories of FRAX® showed good performance in predicting fractures in Indian postmenopausal women. Thus, it may be utilized for decision regarding treatment and referral for osteoporosis.

Abstract
Areal bone mineral density (aBMD) is currently the gold standard for the diagnosis of osteoporosis, however, it has its own pitfalls. Trabecular bone score (TBS), a novel tool in the evaluation of osteoporosis is an indirect indicator of bone microarchitecture. It is a textural index that evaluates pixel gray-level variations in the lumbar spine DXA (dual energy X-ray absorptiometry) image. Both cross-sectional and longitudinal studies have demonstrated that TBS may independently predict fragility fractures. TBS can also be used to adjust FRAX probabilities of fracture, though data available till date doesn't support any additional benefit. TBS also shows an improving trend with anti-osteoporotic treatment; however, the least significant change (LSC) is high that it takes more than 2 years for the change to manifest. TBS is also used in the evaluation of bone strength in cases of secondary osteoporosis. Though TBS predicts fracture risk independently in both genders, with the currently available data, it cannot be recommended as a standalone tool for decision regarding treatment of osteoporosis. TBS can be used as a tool to complement BMD in assessment of bone health. Additional studies are needed to assess its utility in clinical practice.

Abstract
McCune Albright syndromeis a rare disorder that presents with multiple endocrine abnormalities. We report the case of a 24-year-old woman who presented with right lower limb pain, with no preceding trauma or fracture. On examination she was noted to have coarsened facial features, acral enlargement, bitemporal hemianopia, galactorrhoea and multiple café-au-lait macules. She gave history of precocious puberty, having attained menarche at 7 years of age. Biochemical investigations revealed hyperprolactinaemia, with unsuppressed growth hormone levels following a glucose load and subclinical hyperthyroidism. Technetium-99m methylene diphosphonate bone scan showed polyostotic fibrous dysplasia, MRI of the brain showed a pituitary macroadenoma. Thus she was diagnosed to have McCune Albright syndrome with multiple endocrine manifestations. She was treated with parenteral zoledronate for her bony lesions and initiated on cabergoline for plurihormonal pituitary macroadenoma. She is planned to be on close follow-up to assess for clinical improvement and appearance of other manifestations.

Abstract
Exogenous steroid use is the most common cause of Cushing syndrome. With the use of glucocorticoids(GC) for a variety of diseases, the indiscriminate use of this group of drugs has increased. We present a family from which both children were brought with features suggestive of Cushing syndrome. On evaluation, they were found to have suppressed hypothalamic pituitary adrenal (HPA) axis, signifying steroid use from exogenous sources. On further evaluation by a psychiatrist, the mother who was on treatment for chronic depression confessed that she had bought dexamethasone tablets over the counter, and administered the same, mixed with fruit juices to her sons. The family was counselled regarding the consequences of chronic steroid abuse and the children were started on replacement doses of prednisolone. Certain features like posterior subcapsular cataract, glaucoma, avascular necrosis of femur and psychosis are specific to exogenous Cushing syndrome. Despite efforts to understand the effects of long-term steroid treatment on the HPA axis, it is not yet clear as to which patients will have prolonged HPA axis suppression. The time taken for the recovery of HPA axis remains variable. Also, HPA axis suppression due to exogenous steroids may present as acute adrenal crisis. Hence, it is important to start these patients on replacement dose of steroids and also educate them regarding the increased requirement of steroids during stress.

Abstract
Lingual thyroid is an abnormal mass of ectopic thyroid tissue seen in the base of tongue caused due to aberrant embryological development. It is often asymptomatic but may cause local symptoms, such as dysphagia, dysphonia, and upper airway obstruction. In this case, we report a 13-year-old girl who presented with dysphagia and breathing difficulty. Local examination revealed thyroid tissue in the posterior aspect of the tongue. Thyroid scintigraphy showed abnormal tracer uptake at base of tongue. Hormonal test showed subclinical hypothyroidism. She was treated with Levothyroxine.

Abstract
Non-enzymatic glycation of extracellular matrix with (U-13C5)-d-ribose-5-phosphate (R5P), enables in situ 2D ssNMR identification of many deleterious protein modifications and crosslinks, including previously unreported oxalamido and hemiaminal (CH3-CH(OH)NHR) substructures. Changes in charged residue proportions and distribution may be as important as crosslinking in provoking and understanding harmful tissue changes.

Abstract
HIV exposed children are vulnerable to developmental delay irrespective of their HIV status due to combined effect of risk factors like poverty, prenatal drug exposure, stress and chronic illness in family and malnutrition. This cohort study assessed the development of 50 HIV exposed children aged 6-18 months at a Pediatric Centre of Excellence in HIV care in India. The development was assessed using Development Assessment Scale for Indian Infants (DASII) at enrolment, 3 and 6 months later. The development quotient (DQ) scores and proportion of children with developmental delay (DQ ≤ 70) were compared among two sub-groups, HIV infected (HI) and HIV exposed uninfected (HEU) children. The various social and clinical factors affecting development were studied by univariate and multivariate analysis. Prevalence of developmental delay was 2.4% in the HEU (n = 41), and 33.3% in HI (n = 9). The DQ of HI was significantly lower than that of HEU at all three assessments. The DQ of HI were also significantly lower compared to the HEU at ages 12.1-18 months (83.37 ± 20.73 vs 94.68 ± 5.13, p = 0.005) and 18.1-24 months (84.55 ± 15.35 vs 94.63 ± 5.86, p = 0.006) respectively. The development of HEU was adversely affected by lower socioeconomic status and presence of wasting. In addition, development of HI was also adversely influenced by presence of stunting and opportunistic infections, advanced disease stage and shorter ART duration. We conclude that with optimum care, HEU can have a normal development, while a considerable proportion of HI may continue to have delayed development.

Abstract
In the modern era of surgery, minimally invasive surgery is increasingly applied for excision of gastrointestinal stromal tumors. Site, size and tumor location are important factors that affect the surgical approach and excision. We performed a laparoendoscopic transgastric enucleation of a 4-cm pericardial endophytic gastrointestinal stromal tumor (GIST) using an energy device. The surgery was successful and post-operative recovery uneventful. No tumor recurrence was detected on surveillance gastroscopy. In the safe hands of a well-trained laparoscopic upper gastrointestinal surgeon, pericardial GIST can be enucleated safely by this method. The avoidance of surgical staplers is not only cost-effective, but also reduces the risk of associated complications.

Abstract
The velocity of impact between an object and the human head is a critical factor influencing brain injury outcomes but has not been explored in any detail in animal models. Here we provide a comprehensive overview of the interplay between impact velocity and injury severity in a well-established weight-drop impact acceleration (WDIA) model of diffuse brain injury in rodents. We modified the standard WDIA model to produce impact velocities of 5.4, 5.85 and 6.15 m/s while keeping constant the weight and the drop height. Gradations in impact velocity produced progressive degrees of injury severity measured behaviourally, electrophysiologically and anatomically, with the former two methods showing greater sensitivity to changes in impact velocity. There were impact velocity-dependent reductions in sensorimotor performance and in cortical depth-related depression of sensory cortex responses; however axonal injury (demonstrated by immunohistochemistry for β-amyloid precursor protein and neurofilament heavy-chain) was discernible only at the highest impact velocity. We conclude that the WDIA model is capable of producing graded axonal injury in a repeatable manner, and as such will prove useful in the study of the biomechanics, pathophysiology and potential treatment of diffuse axonal injury.
