Flow cytometric detection of T-cell clonality is challenging, particularly in differential diagnosis of immature T-cell proliferations. Studies have shown utility of TRBC1, in conjunction with other T-cell markers, as reliable means to identify T-cell clonality by flow cytometry. One limitation of surface TRBC1 (sTRBC1) evaluation is it cannot be detected in surface CD3 (sCD3)-negative T cells, such as normal or abnormal immature T-cell precursors. Here, we assess surface and cytoplasmic TRBC1 expression patterns in the differential diagnosis of T-lymphoblastic leukemia/lymphoma (T-ALL) vs normal thymocyte expansions.

Forty-three samples containing T-ALL, thymoma, normal thymus, and/or indolent T-lymphoblastic proliferation (i-TLBP), were evaluated.

All 24 cases with normal thymocytes or i-TLBPs revealed a characteristic and reproducible sCD3/sTRBC1 expression pattern indicative of polytypic T-cell maturation. selleckchem In contrast, all 19 T-ALLs lacked this polytypic maturation pattern and were either completely negative for sCD3/sTRBC1 or showed a minor sCD3-positive subset with a monotypic TRBC1 expression pattern. Cytoplasmic TRBC1 evaluation in 9 T-ALLs demonstrated a monotypic intracellular TRBC1-positive (n = 4) or TRBC1-negative (n = 5) expression, indicative of clonality.

Our findings demonstrate flow cytometric evaluation of surface and cytoplasmic TRBC1 expression can aid detection of T-cell clonality and differential diagnosis of immature T-cell proliferations.

Prenatal psychosocial factors predict breastfeeding practices but are not assessed in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).

This study examined how prenatal perceptions of WIC's breastfeeding recommendations were associated with early breastfeeding outcomes.

This study used longitudinal data from a national sample of 2,053 pregnant participants in the WIC Infant and Toddler Feeding Practices Study-2 (WIC ITFPS-2) in 2013, the only national data assessing prenatal perceptions of WIC's breastfeeding recommendations. Early breastfeeding outcomes included breastfeeding initiation, breastmilk first fed after birth, breastfeeding in the first hour, breastmilk first fed after leaving the hospital, and breastfeeding status at the first and third month. The primary predictor was the participant's prenatal perception of whether WIC recommended breastfeeding only or not. Log binomial regression was used with adjustment for socio-demographics, previous breastfeeding, WICor future intervention.
Prenatal perception of WIC's breastfeeding recommendations can be a new psychosocial predictor of breastfeeding and a possible target for future intervention.
To determine the incidence and risk factors of preterm white matter injury (WMI; periventricular-intraventricular hemorrhage (PIVH) and/or periventricular leukomalacia (PVL)).

Prospective cohort study.

Level-3 neonatal intensive care unit.

Inborn preterm neonates (n=140) delivered at <32 weeks gestation or birthweight <1500 g.

Serial cranial ultrasounds were performed at postnatal ages of 3 days (±12hr), 7 (±1) days, 21 (±3) days and 40 (±1) weeks postmenstrual age (PMA). PIVH and PVL were graded as per Volpe and De-Vries criteria, respectively. Univariate followed by multivariate analysis was done to evaluate risk factors for PIVH and PVL.

The primary outcome was the incidence of preterm WMI. The secondary outcomes were evaluation of risk factors and natural course of WMI.

The mean (range) gestation and birth weight of enrolled neonates were 29.7 (24-36) weeks and 1143 (440-1887) g, respectively. PIVH occurred in 25 (17.8%) neonates. PVL occurred in 34 (24.3%) neonates. None of them were grade III or IV PVL. Preterm WMI (any grade PIVH and/or PVL) occurred in 52 (37.1%) neonates. Severe PIVH (grade III/separate notation) and cystic PVL occurred in 7 (5%) and 5 (3.6%) neonates, respectively. On multivariate analysis, none of the presumed risk factors were associated with PIVH. However, hemodynamically significant patent ductus arteriosus, and apnea of prematurity were significantly associated with increased risk of PVL.

Significant WMI occurred only in one-third of the cohort which is comparable to that described in literature from the developed countries.

To identify clinical and laboratory features that differentiate dengue fever patients from MIS-C patients and determine their outcomes.

This comparative cross-sectional study was done at tertiary care teaching institute. We enrolled all hospitalized children aged 1 month - 18 years and diagnosed with either MIS-C and/or dengue fever according to WHO criteria between June and December, 2020. Clinical and laboratory features and outcomes were recorded on a structured proforma.

During the study period 34 cases of MIS-C and 83 cases of Dengue fever were enrolled. Mean age of MIS-C cases (male, 86.3%) was 7.89 (4.61) years. Of 34 cases, MIS-C with shock was seen in 15 cases (44%), MIS-C without shock, 17 cases (50%) and Kawasaki disease-like presentation in 2 cases (6%). Patients of MIS-C were younger as compared to dengue fever (P=0.002). Conjunctival injection and swelling of hand and feet were more commonly seen in MIS-C. Abdominal pain and erythematous rash were more common in dengue fever. Of the inflammatory markers, mean C reactive protein was higher in MIS-C patients, than dengue fever patients [100.
