Pediatric SAPHO syndrome with pleural effusion: case report of a unique finding in a rare disease.

Synovitis, acne, pustulosis, hyperostosis, osteitis (SAPHO) syndrome is a rare autoinflammatory disease characterized by bone inflammation and skin manifestations including acne, palmoplantar pustulosis, psoriasis, or hidradenitis suppurativa. SAPHO syndrome is considered on the same spectrum as chronic nonbacterial osteomyelitis/chronic recurrent multifocal osteomyelitis (CNO/CRMO), the former often being the nomenclature in adults and the latter in children. The diagnosis is made on patterns of clinical manifestations and is a diagnosis of exclusion. While skin and bone manifestations are commonly described with SAPHO syndrome, pleural involvement is rare, and few cases have been described in the literature, especially in pediatric patients. Herein we present a 14-year-old female with a past medical history of hidradenitis supprtiva, eczema, psoriasis, and a prior episode of culture-negative osteomyelitis who presented to the emergency room with chief complaints of right sided pain with inspiration and back pain. Exam revealed palmoplantar pustulosis, hidradenitis supprativa, psoriasis, and tenderness of vertebrae. Imaging showed a right sided pleural effusion and multiple sites of osteitis. Laboratory evaluation revealed elevated inflammatory markers, an exudative pleural effusion with neutrophilic predominance, and no evidence of malignancy, infection, or immunodeficiency. The patient was diagnosed with SAPHO syndrome and treated with naproxen, methotrexate, and golimumab with significant improvement including resolution of the pleural effusion. Pediatric SAPHO syndrome is a rare disease that classically causes osteitis and skin manifestations. This case highlights that pleural effusion can be a rare manifestation of pediatric SAPHO syndrome. Patients with suspected SAPHO syndrome with respiratory symptoms should be evaluated for pleural effusion.

FLI1 in PBMCs contributes to elevated inflammation in combat-related posttraumatic stress disorder

Post-traumatic stress disorder (PTSD) is a debilitating psychiatric condition with significant public health implications that arise following exposure to traumatic events. Recent studies highlight the involvement of immune dysregulation in PTSD, characterized by elevated inflammatory markers. However, the precise mechanisms underlying this immune imbalance remain unclear. Previous research has implicated friend leukemia virus integration 1 (FLI1), an erythroblast transformation-specific (ETS) transcription factor, in inflammatory responses in sepsis and Alzheimer’s disease. Elevated FLI1 levels in peripheral blood mononuclear cells (PBMCs) have been linked to lupus severity. Yet, FLI1’s role in PTSD-related inflammation remains unexplored. In our study, PBMCs were collected from Veterans with and without PTSD. We found significantly increased FLI1 expression in PBMCs from PTSD-afflicted Veterans, particularly in CD4+ T cells, with no notable changes in CD8+ T cells. Stimulation with LPS led to heightened FLI1 expression and elevated levels of inflammatory cytokines IL-6 and IFNγ in PTSD PBMCs compared to controls. Knockdown of FLI1 using Gapmers in PTSD PBMCs resulted in a marked reduction in inflammatory cytokine levels, restoring them to control group levels. Additionally, co-culturing PBMCs from both control and PTSD Veterans with the human brain microglia cell line HMC3 revealed increased inflammatory mediator levels in HMC3. Remarkably, HMC3 cells co-cultured with PTSD PBMCs treated with FLI1 Gapmers exhibited significantly lower inflammatory mediator levels compared to control Gapmer-treated PTSD PBMCs. These findings suggest that suppressing FLI1 may rebalance immune activity in PBMCs and mitigate microglial activation in the brain. Such insights could provide novel therapeutic strategies for PTSD.

In Vitro Maturation of Oocytes Obtained from Ovarian Cortex Among Postpubertal Hematological Cancer Patients Undergoing Fertility Preservation.

Purpose: In vitro maturation (IVM) of oocytes obtained from ovarian tissue during ovarian tissue cryopreservation (OTC) is a technique for fertility preservation in patients with cancer obviating the need to postpone chemotherapy initiation. Little is known about IVM outcomes in hematological malignancies, especially post-chemotherapy. The purpose of this study was to evaluate the effect of cytotoxic treatment on the potential to retrieve immature oocytes and mature them in vitro and examine the association between serum inflammatory markers and these results. Methods: In this retrospective study, we evaluated inflammation markers, including B symptoms and IVM outcomes of 78 chemotherapy-naive and exposed patients diagnosed with Hodgkin lymphoma (HL), non-Hodgkin lymphoma (NHL), acute lymphoblastic leukemia (ALL), or acute myeloid leukemia (AML). Results: The mean number of oocytes found was 7.2 ± 7.2. The average number of oocytes matured by IVM was 2.8 ± 3.5, and a mean IVM rate was 32.1 ± 27.7%. All patients in the ALL and AML groups had previous exposure to chemotherapy before OTC, compared with 50.0% (7/14) and 31.9% (15/47) in the NHL and HL groups, respectively. Among patients with lymphoma, chemotherapy exposure was associated with the reduced number of retrieved oocytes (9.8 ± 7.7 vs. 5.3 ± 5.7 oocytes, p = 0.049) in the HL group but not with the number of mature oocytes or IVM rate. B symptoms were not associated with IVM outcomes. Lymphocyte count (ß = 1.584; p = 0.038) and lactate dehydrogenase (ß = 0.009; p = 0.043) were the only significant parameters associated with the number of matured oocytes in a linear regression model. Conclusion: IVM is a promising assisted reproductive technology, which holds great potential for patients in need of urgent fertility preservation or those who cannot receive hormonal stimulation. Our results demonstrate the feasibility of the technique even in the presence of B symptoms and elevated inflammation markers and in patients with previous exposure to chemotherapy.

Determining Diagnostic Sensitivity: A Comparison of Rose Bengal Test, Coombs Gel Test, ELISA and Bacterial Culture in Brucellosis Diagnosis-Analyzing Clinical Effectiveness in Light of Inflammatory Markers.

Brucellosis is a zoonotic infectious disease. It is estimated that the number of cases reported today is much less than the actual number. We still have difficulty in diagnosing the disease and its organ involvement. In this sense, new approaches that can be useful in clinical practice are required, and we aimed to evaluate this situation in our study. 171 of 213 patients followed in our center between January 2021 and April 2024 were included in the study. A total of 150 patients were included in the study as a control group. Rose Bengal test (RBT), Coombs gel test (CGT), enzyme-linked immunosorbent assay (ELISA), and automated blood culture were used for diagnosing brucellosis. Complete blood count, sedimentation, C-reactive protein, and biochemical parameters were obtained. Inflammation markers such as neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, systemic immune-inflammation index, and systemic inflammation response index were calculated. The most successful results in the diagnosis were ELISA (89.4%), RBT (88.3%), CGT (83%), and blood culture (34.8%). For diagnosing sacroiliitis and spondylodiscitis, instead of resorting to expensive methods like magnetic resonance, a combination of ELISA positivity with elevated acute phase reactants and inflammatory markers could be significantly instructive. Optimizing diagnostic algorithms and exploring novel diagnostic approaches, such as inflammatory markers, hold promise for improving diagnosis and management.

“Iliacus muscle abscess as an unexpected cause of posterior hip pain in a healthy young adult female”: a case report

BackgroundIliacus muscle abscess is an uncommon but potentially life-threatening condition that can present with nonspecific symptoms, posing diagnostic challenges. This case report highlights the importance of considering iliopsoas abscess in patients presenting with fever and hip pain, especially in the absence of obvious risk factors or penetrating trauma. The novelty of this case lies in its atypical presentation mimicking a respiratory viral infection and musculoskeletal injury, impeding accurate diagnosis and appropriate management.Case PresentationA previously healthy 21-year-old female who had a mechanical fall 3 weeks prior presented with fever, right hip pain, and respiratory symptoms, initially suggestive of a respiratory infection and musculoskeletal injury. However, initial investigations revealing a markedly high C-reactive protein (CRP) concentration prompted further computed tomography (CT) imaging of her abdomen and pelvis, which uncovered an iliopsoas abscess presumably stemming from antecedent trauma. Subsequent CT guided aspiration along with culture-sensitive antibiotics led to successful treatment and resolution of her symptoms.ConclusionsThis case emphasizes the importance of considering iliopsoas abscess as a possible differential, even in young patients without typical risk factors. Markedly elevated inflammatory markers such as CRP concentrations can serve as a vital indicator, directing attention towards the possibility of septicemia or the presence of an occult abscess, facilitating prompt imaging and accurate diagnosis.

Monogenic interferon-mediated diseases: novel phenotype and genotype characteristics from a Saudi population.

IFN-mediated diseases are mendelian innate immunodysregulatory disorders that present early in life with fevers, sterile organ inflammation, and a high type-I IFN-response gene signature in peripheral blood cells. To date, monumental discoveries of novel genetic variants with various phenotypic features have been recognised. We aimed to describe the genotype and phenotype findings in Saudi children diagnosed with autoinflammatory interferonopathy and to report novel findings. This is a descriptive retrospective cohort study of children with genetically confirmed type I interferonopathies. Medical records were reviewed for demographic, family history, clinical and laboratory data. All patients underwent genetic testing. A total of 20 patients (11 females) were included in the study. Sixteen patients (80%) presented within the first 2 years. The median age of disease onset was 0.87 years (IQR: 0.5-2) and the median age of diagnosis was 4.5 years (IQR: 2-7.5). The rates of consanguinity and family history of affected members were high (88% and 47%, respectively). Among the cohort of patients, whole exome sequencing was conducted for 15 patients. Three patients underwent targeted gene tests, and 2 patients had a leukoencephalopathy genetic panel. Eight patients were diagnosed with Aicardi-Goutières syndrome, attributed to variants in the RNASEH2A, RNASEH2C, and IFIH1 genes. Additionally, 2 patients were identified with STING-associated vasculopathy with onset in infancy linked to the TMEM173 variant. One patient exhibited chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature due to PSMB8, and another patient had DNase II. Moreover, 8 patients presented with rare interferonopathy conditions, including three with ISG15, 3 with ZNFX1, 1 with the SOCS1 variant, and 1 the STAT1 variant. Of 12 variants, six (50%) found to have novel genetic variants. The most frequent features were fever (75%), neurology (70%), mucocutaneous (60%), gastrointestinal (50%), and pulmonary (50%). Hypogammaglobinaemia and recurrent infections were seen in (45%) and (20%), respectively. Fifteen patients (75%) had elevated inflammatory markers. The majority of patients received intensive treatment, including corticosteroids, JAK inhibitors, IVIG, and various immunosuppressive agents. Despite these interventions, a partial response to treatment was observed, and cumulative disease damage primarily manifested as growth failure and developmental delay. Our findings support the previous reports; early-onset fever, neurology, and respiratory features should raise the suspicion of interferonopathies. However, there is eminent evidence of phenotypic variability. Our data also expanded the spectrum of clinical findings in relation to novel genetic variants.

Study of the Relationship between Platelet Distribution Width, Red Blood Cell Distribution Width and Insulin Resistance in Type 2 Diabetic Patients with Non-Alcoholic Fatty Liver Disease

Abstract Background Insulin resistance is identified as an impaired biological response to insulin stimulation of target tissues, primarily the liver, muscle, and adipose tissue. The metabolic consequences of insulin resistance can result in hyperglycaemia, hypertension, dyslipidaemia, visceral adiposity, hyperuricemia, elevated inflammatory markers, endothelial dysfunction, and a prothrombotic state. Progression of insulin resistance can lead to metabolic syndrome, non- alcoholic fatty liver disease, and type 2 diabetes mellitus. Aim of the Work We aimed by our study to assess the relationship of platelet distribution width and red blood cell distribution width with insulin resistance in patients with type 2 diabetes with and without non-alcoholic fatty liver disease (NAFLD) and to check if platelet distribution width or red blood cell distribution width could be easy predictors of insulin resistance. Patients and Methods The present study is a Case Control Study was conducted in Ain Shams University Hospital. This study includes 80 subjects with matched age and sex. Results The present study results confirmed that low RDW was associated with increased risk of developing diabetes mellitus. Their study found that RDW is negatively correlated with waist and FG, insulin and TG concentrations. We also found that the group with the lowest quartile of RDW had the highest glucose, insulin and HOMA levels. Moreover, our results were found that there is a significant negative correlation of RDW with poor glycemic control. Our results also found that decreased levels of red blood cell distribution widths (RDW) were all associated with increased fasting insulin. Our study was documented a negative correlation between HbA1c and the platelet index PDW. Conclusion In our study, we found a relation between insulin resistance and red blood cell distribution width. RDW (fl) could be used to discriminate between patients with type II diabetes and controls.

Cardiac Follow up of Pediatric Patients Presented with Covid-19 Cardiovascular Affection

Abstract Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is typically very mild and often asymptomatic in children. A complication is the rare multisystem inflammatory syndrome in children (MIS-C) associated with COVID-19 carditis, presenting 4–6 weeks after infection as high fever, organ dysfunction, and strongly elevated markers of inflammation. Aim of the Work To Follow up of Pediatric Patients Presented with Covid-19 Cardiovascular Affection. Patients and Methods This was an analytical Prospective Cohort study conducted on 33 patients with post COVID-19 infection. all patients were subjected to the following:(demographic data, clinical signs & symptoms, laboratory investigations and Echocardiogrsphy at presentation, 1,6 weeks and 3months follow up from January 2021 to August 2021 to evaluate the short and mid- term effect of COVID-19 infection on cardiac function, and outcomes for pediatric multisystem inflammatory syndrome related to covid-19. Results In our study all patients fulfilled criteria of MIS-C presented with Kawasaki disease(KD)- like symptoms and gastrointestinal symptoms in addition to fever with shock or cardiac dysfunction. Our patients were presented with the following vital data: tacycardia with mean of 132.82 (18.74) beat/minute, hypotension with mean of 88.03 (14.06) (mmhg) for systolic blood pressure & mean of 49.39 (14.78) mmhg for diastolic blood pressure, spo2 mean 96.27 (2) %, high grade fever of mean 38.36(0.79). KD-like features were seen in many patients (skin rash in 66.7%, conjunctivitis in 75.8% and Cardiovascular abnormalities were seen in 100% e.g. (myocardial dysfunction, valvular regurgitation, pericardial effusion and shock. Our MIS-C patients had signs and symptoms of an inflammatory state e.g.(fever, rash, conjunctivitis and diarrhea(gastroenteritis). Conclusion MIS-C is a hyper-infammatory syndrome affecting multiple organs especially the heart and is triggered by SARS-CoV-2 infection. It is usually seen 2–4 weeks following infection. In our study,IVIG and steroids might have a beneficial role in MIS-C management.

Follow Up of Cardiovascular Affection in Covid-19 Pediatrics Survivors

Abstract Background Multisystem inflammatory syndrome in children (MIS-C) associated with COVID-19 is a rare complication of (SARS-CoV-2) infection. Presenting (4–6) weeks after infection as high fever, organ dysfunction, and strongly elevated markers of inflammation which is mostly due to post infection immune reaction. Aim of the Work to evaluate cardiac outcomes 6 months after initial presentation with MIS-C associated with cardiac affection. Patients and Methods This was a retrospective cohort study on 28 patients (19 boys & 9 girls) who were diagnosed as multi system inflammatory syndrome in children (MIS-C) related to COVID19 six months ago at children`s hospital, Ain shams university from January 2021 to October 2021. All patients were subjected to the following: (demographic data, clinical signs and symptoms, laboratory investigations) in the acute phase (obtained from patient’s medical records) and at follow up after 6- months. Results in our study all patients fulfilled criteria of MIS-C presented with fever, shock or cardiac dysfunction and gastrointestinal symptoms in addition to conjunctivitis and skin rash. Our patients were presented with hypotension with mean systolic blood pressure (87) mmHg & mean diastolic blood pressure (48) mmHg. Regarding symptoms: vomiting was seen in (60.7%), diarrhea in (32.1%), conjunctivitis in (82.1%) and cardiovascular abnormalities were seen in (100%) in the form of (myocardial dysfunction in (50%), coronary dilatation in (28.8%), valvular regurgitation in (100%) and pericardial effusion in (7.2%)). After 6 months there was significant improvement regarding vital signs. Regarding laboratory findings: at time of presentation most of the patients had high CRP, high troponin, and high CK-MB. On follow up after 6 months, all patients had normal values. Conclusion Our follow up study suggests that functional recovery and coronary outcomes are good in multisystem inflammatory syndrome in children.

Vascular threads and nephron nests: exploring the association between Takayasu arteritis and membranous nephropathy

Takayasu arteritis (TA) primarily causes ischaemic nephrosclerosis but can occasionally be associated with glomerulopathy. We report a case of a female in her twenties with PLA2-negative, THSD7A-positive membranous nephropathy (MN) refractory to rituximab, who presented with neck pain and new-onset hypertension. Blood work showed elevated inflammatory markers. Imaging of the head and neck revealed focal dilation and irregularity of the vertebral arteries, consistent with TA. The patient was started on treatment with steroids, followed by mycophenolate mofetil, which led to the resolution of symptoms and nephrotic syndrome. This case highlights an uncommon sequence of events, with MN presenting before TA, underscoring the need to consider TA in differentials for patients with MN. Notably, this is the first reported case in a young female, emphasising the need for further understanding of TA-associated glomerular diseases. Additionally, the presence of THSD7A in MN, despite negative malignancy workup, is also noteworthy.

Intrarectal Migration of an Intrauterine Device: A Case Study and Review of Literature

Intrauterine devices (IUDs) are a widely used and generally safe method of long-term contraception. However, complications such as uterine perforation and migration can occur, although they are rare. This article presents a case of a 30-year-old woman with a history of two pregnancies and deliveries, who had a copper IUD inserted two years prior during the lactation period. She was admitted with severe pelvic pain and constipation lasting for three days, without externalized gastrointestinal bleeding or vomiting. Clinical examination revealed generalized abdominal tenderness with hypogastric guarding, while laboratory tests indicated elevated inflammatory markers. Imaging studies, including abdominal ultrasound and CT scan, revealed the migration of the IUD and its partial perforation into the rectal ampulla. Emergency surgery was performed, including the repair of a rectal perforation, lateral protective colostomy, and appendectomy. The postoperative course was uneventful, and colonic continuity was restored six weeks later. This case underscores the importance of considering IUD migration in a patients presenting with abdominal pain and highlights the need for timely diagnosis and intervention to prevent serious complications. Regular follow-up and patient education on the potential risks and signs of IUD complications are essential for early detection and management.

Comprehensive immune modulation mechanisms of Angong Niuhuang Wan in ischemic stroke: Insights from mass cytometry analysis.

Angong Niuhuang Wan (AGNHW, ), is a classical medicinal formula in Traditional Chinese Medicine (TCM) that has been appreciated for its neuroprotective properties in ischemic cerebral injuries, yet its intricate mechanisms remain only partially elucidated. This study leverages advanced Mass cytometry (CyTOF) to analyze AGNHW's multifaceted immunomodulation effects in-depth, emphasizing previously underexplored areas. AGNHW mitigated monocyte-derived macrophages (MoDM) infiltration in the brain, distinguishing its effects on those from microglia. While the vehicle group exhibited elevated inflammatory markers like CD4, CD8a, and CD44 in ischemic brains, the AGNHW-treated group attenuated their expressions, indicating AGNHW's potential to temper the post-ischemic inflammatory response. Systemically, AGNHW modulated fundamental immune cell dynamics, notably augmenting CD8+ T cells, B cells, monocytes, and neutrophil counts in the peripheral blood under post-stroke conditions. Intracellularly, AGNHW exhibited its targeted modulation of the signaling pathways, revealing a remarked inhibition of key markers like IκBα, indicating potential suppression of inflammatory responses in ischemic brain injuries. This study offers a comprehensive portrait of AGNHW's immunomodulation effects on ischemic stroke, illuminating its dual sites of action-both cerebral and systemic-and its nuanced modulation of cellular and molecular dynamics.

Pediatric inflammatory multisystem syndrome or Kawasaki disease - continuous challenges in Pediatrics - case report

Introduction. Kawasaki disease (KD) and pediatric inflammatory multisystem syndrome (PIMS) are similar vasculitis conditions affecting medium and small vessels, particularly the coronary arteries. This study aimed to highlight diagnostic and treatment challenges in a case initially diagnosed as PIMS, which evolved into atypical KD. Materials and methods. A 2-year-10-month-old male was admitted with a high fever persisting for 6 days, unresponsive to antipyretics. Results. On admission, the patient exhibited a poor general condition, pale skin, non-pruritic erythematous rash, and enlarged, non-painful lymph nodes. Laboratory tests showed elevated inflammatory markers, leukocytosis with neutrophilia, hypoalbuminemia, liver enzyme abnormalities, altered cardiac markers, and elevated D-dimers, but no initial echocardiographic changes. Positive SARS-CoV-2 antibodies led to an initial PIMS diagnosis, and treatment with intravenous methylprednisolone, antiplatelet, anticoagulant therapy, and hepatoprotective agents was started. The patient’s condition initially improved but then worsened with febrile spikes, rash, neutropenia, thrombocytopenia, anemia, and coronary artery dilation on echocardiography. This led to a diagnosis of KD with atypical onset, and treatment with immunoglobulin, antiplatelet, and anticoagulant therapy was initiated. The patient’s condition improved slowly. Conclusions. KD and PIMS share overlapping characteristics, making them difficult to distinguish. There is no definitive criterion to differentiate KD and PIMS, leading to potential diagnostic errors.

Granulomatous Panniculitis as an Initial Manifestation of Sjögren Syndrome.

A 65-year-old woman presented with unexplained weight loss, recurrent fever, and a dermatosis with painful nodules on the extremities. Biopsies showed focal lobular panniculitis with neutrophilic microgranulomas. Comprehensive investigations ruled out infection and hematologic and solid organ neoplasms. Laboratory results showed anti-Ro/SSA and anti-La/SSB antibody positivity, and elevated inflammatory markers. Dry mouth and eye were confirmed. The diagnosis of Sjögren syndrome with cutaneous panniculitis was established. Prednisone treatment with 30 mg/d resulted in remission of fever and pain improvement. This case emphasizes Sjögren syndrome as an autoimmune disease with multiple cutaneous manifestations and highlights its association with granulomatous panniculitis.

Impact of vitamin D deficiency on iron status in children with type I diabetes

Vitamin D deficiency (VDD) and anemia are both public health nutrition concerns. An association between VDD and anemia has been suggested in various healthy and diseased populations. The current study aimed to elucidate the effect of VDD on iron status in children with type I diabetes mellitus (T1DM). The study recruited two groups of children with T1DM: control group comprised of 38 T1DM children with sufficient vitamin D (> 30 ng/ml) and a case group, consisted of 52 T1DM children with VDD (< 20 ng/ml). Both groups had comparable gender, age, BMI, and disease duration. The laboratory measurements included analysis of blood indices, markers of iron metabolism, hepcidin and inflammatory markers included interleukin 6 (IL-6) and C-reactive protein (CRP). Compared to control group, T1DM children with VDD differs specifically in terms of some markers of blood indices, such as decreased hemoglobin and increased red blood cell distribution width. Moreover, decreased serum iron, ferritin, total iron-binding capacity and transferrin along with elevated inflammatory markers were observed in case group. Results of the study indicated that VDD had increased the risk of iron deficiency anemia in children with T1DM as well as inflammatory related anemia. Furthermore, in T1DM children, VDD had raised the incidence of both absolute and functional iron deficiency, with greater incidence of the former. This study may indicate that VDD may be a risk factor that may worsen iron deficiency anemia in T1DM.

Exploring outcomes in hospitalized patients with COVID-19 based on nutritional status: Comparing those with and without a cancer diagnosis.

e23068 Background: This study explores how nutritional status impacts COVID-19 outcomes, particularly in patients with cancer. Obesity is known to heighten risk of adult respiratory distress syndrome in COVID-19, malnutrition and its associated effects related to the immune response, respiratory compromise, debility, and other adverse outcomes has not been well defined in this patient population. Methods: In this retrospective cohort study, we examined data from the Charleston Area Medical Center’s (CAMC) COVID-19 Registry, involving 5,479 adult, symptomatic, PCR-positive COVID-19 hospitalized patients (3/1/20 to 1/20/24). Low nutritional status (LNS) was defined as Body Mass Index (BMI) &lt; 18.5 kg/m² or serum albumin &lt; 3.5g/dL). Demographics, comorbidities, lab values, treatments, and outcomes were assessed. Propensity score matching (3:1) non-cancer patients vs those with an active cancer diagnosis was undertaken using sex, age, and BMI. SAS 9.4 was utilized for the analysis. The groups were compared using Chi-square/Fisher’s Exact tests for categorical variables and t-tests for continuous variables. Multivariate analysis was utilized to determine predictors of adverse outcomes. Results: A cohort of 1,146 non-cancer and 382 active cancer patients were included in the study. The LNS subgroup had a higher frequency of active cancer (29.2% vs 19.3%, p &lt; 0.001), higher rates of diabetes (27.0% vs17.8%, p = 0.03) and chronic kidney disease (18.8% vs 11.7%, p = 0.02). They had greater frequencies of abnormal ferritin levels (57.8% vs 42.7%, p &lt; 0.001), CRP levels &gt; 3 mg/L (96.6% vs 90.3%, p &lt; 0.001), and elevated procalcitonin levels &gt; 0.05 ng/mL (71.2% vs 50.1%, p &lt; 0.001). LNS patients had a higher mortality rate (22.3% vs 9.7%, p &lt; 0.001), a higher need for mechanical ventilation (19.3% vs 9.5%, p &lt; 0.001), and intensive care unit (ICU) admission (35.7% vs 19.5%, p &lt; 0.001. Predictors of mortality included LNS (OR = 2.2, 95%CI [1.5-3.2], p &lt; 0.001), an active cancer diagnosis (OR = 1.7, 95% CI [1.2-2.6], p = 0.003), chronic kidney disease (OR = 1.8 95%CI [1.3-2.5], p = 0.004) and concurrent bacterial pneumonia (OR = 4.9 95%CI [3.3-7.2], p &lt; 0.001). Conclusions: In patients with COVID-19, those with LNS had higher rates of co-morbid conditions including active cancer, higher rates of elevated inflammatory markers, mechanical ventilation, ICU admission, and mortality. Predictors of mortality included concurrent bacterial pneumonia, cancer diagnosis and chronic kidney disease, with LNS increasing the risk of mortality by more than two-fold. These results support the recommendation of early nutritional assessment and a multi-disciplinary approach to aggressive nutritional support in the COVID-19 patient population particularly in those with a concurrent high-risk condition such as cancer.

Association between oral health and cognitive impairment in older adults: Insights from a Six-year prospective cohort study

ObjectiveThis study aims to investigate the relationships between four baseline oral conditions (periodontal status, dental caries, tooth wear, and dentition) and repeated global cognition or domain-specific cognition (memory, executive function, attention, and verbal fluency) in non-demented older adults over time. MethodsThis prospective cohort study (2011–2019) enrolled 516 non-demented community-dwelling older adults (age ≥ 65) to explore the association between oral health and cognitive function. Global and domain-specific cognition were assessed biennially (four repeats) using a battery of neuropsychological tests. The baseline oral health conditions were examined, including periodontal status, dental caries, tooth wear, and dentition. The association of these oral conditions with cognition was evaluated by generalized linear mixed models. Stratified analyses were performed by important covariates. ResultsOver time, dental caries was associated with poor memory in two different logical memory tests (β^= -0.06 and β^= -0.04). Incomplete dentition with less than 28 teeth was associated with poor performance in attention (β^= -0.05) and verbal fluency (β^= -0.03). These associations became more evident in those with an elevated inflammatory marker (IL-6, β^= -0.11 to -0.08). In contrast, tooth wear was associated with better memory in two different logical memory tests (β^= 0.33 and β^= 0.36) and better executive function (β^= 0.06) over time, and this association became more evident in those with the lowest inflammatory marker (IL-6, β^= 0.10). ConclusionsDental caries and incomplete dentition were associated with poor memory, attention, and verbal fluency performance. Conversely, tooth wear was associated with better memory performance and executive function. Clinical SignificanceFor early prevention of dementia, an evaluation of multiple dental and periodontal status in older adults helps predict the risk of dementia in the preclinical phase. Maintaining intact tooth structure without caries progression and eventually tooth loss may help prevent the worsening of memory, attention, and verbal fluency over time.

Clinical outcome and its correlation with inflammatory markers in SARS-COV-2 patients

Coronaviruses, characterized by a single-stranded RNA genome, present a challenge due to the unclear relationship between elevated inflammatory markers and disease severity. This study examines the correlation between inflammatory markers (D-dimer, serum ferritin, serum LDH, CRP) and clinical outcomes in 62 COVID-19 patients at a medical center in Puducherry, India. Patients were categorized into mild, moderate, or severe based on WHO guidelines. CBC, RFT, D-dimer, serum LDH, serum ferritin, and CRP levels were evaluated at admission and after 72 hours. Most patients with moderate and severe disease experienced ARDS and required oxygen support, with ventilator assistance limited to severe cases. Severe cases were also associated with pulmonary embolism and DIC, leading to mortality in all six severe cases. Higher CRP positivity was noted in moderate and severe cases on days 1 and 3, along with elevated D-dimer, ferritin, and LDH levels, indicating severity. In conclusion, severe illness was marked by significantly elevated levels of CRP, D-dimer, ferritin, and LDH, suggesting their potential as prognostic indicators. Repeated monitoring of these markers may aid in predicting outcomes for severe cases in clinical practice.

Urinary tract infections in young infants with a normal urine dipstick.

To assess missed urinary tract infections (UTI) in febrile infants ≤2 months when adhering to recent guidelines suggesting not to send a urine culture with a negative dipstick. A retrospective cohort study of 308 infants ≤2 months with a positive urine culture admitted in 2013-2023, divided into subgroups without exposure to urine dipstick results: 'urosepsis' (UTI with bacteraemia), 'UTI' (positive urine culture, elevated inflammatory markers, no other cause of fever) and 'bacteriuria' (positive urine culture, not meeting the above-mentioned criteria). After retrieving the dipstick results, the 'missed UTI' group (UTI+ negative dipstick) was described. A negative dipstick was found in 2/20 (10%), 32/127 (25%) and 126/161 (78%) of infants with 'urosepsis', 'UTI' and 'bacteriuria', respectively. In the 'missed UTI' group (n = 34), there were more non-Escherichia coli UTI (68% vs. 9% with positive dipstick, p < 0.001), and lower inflammatory markers (leukocytes 15.5 vs. 17.2 k/μL, p = 0.007, C-reactive protein 21 vs. 58 mg/L, p < 0.001). Three infants had high-grade vesicoureteral reflux (VUR) and renal scarring. There is a non-negligible rate of infants ≤2 months with UTI and without pyuria, including those with urosepsis, VUR and renal scarring. We suggest obtaining a urine culture regardless of dipstick results.

Cardiovascular manifestations in pediatric multisystem inflammatory syndrome associated with COVID-19 in a tertiary care pediatric center in Mexico City

The objective is to expose the cardiovascular alterations in patients diagnosed with pediatric inflammatory multisystem syndrome (PIMS) associated with COVID-19 during the SARS-CoV-2 pandemic, in order to understand the disease, its evolution, and optimal management upon diagnosis. Retrospective, observational, cross-sectional analytical study of patients diagnosed with PIMS according to the criteria of the World Health Organization at the National Institute of Pediatrics, from March 2020 to December 2021. During the study period, 77 patients with PIMS were diagnosed. The results showed correlation between the shock state and alteration of laboratory markers (platelets 144217.29 ± 139321.6 μL [p < 0.001], procalcitonin 27.37 ± 38.37 ng/ml [p = 0.05] and ferritin 1937.87 ± 2562.63 [p < 0.001]). The ventricular function in patients with shock was significantly lower compared to those without shock (49.6 ± 9.1% vs. 58.1 ± 8.4 %; t-Student p < 0.001), as well as injury to the left coronary artery (p = 0.02). There is a correlation between NT-proBNP and ventricular dysfunction (Kruskal-Wallis p = 0.007). Statistical significance was found in the association between death, elevation of inflammatory markers and ventricular dysfunction (p < 0.001). The cardiovascular alterations observed, in order of frequency, were pericardial effusion (25.7%), myocarditis (15%), mild ventricular dysfunction (13.5%) and small coronary aneurysm with predominance of the left coronary artery and the anterior descending one.
