Hospitalisation and mortality among privately insured individuals with COVID-19 in the United States: The role of intellectual disabilities and Neurogenetic disorders.

BACKGROUND: Individuals with intellectual disabilities (IDs) and neurogenetic conditions (IDNDs) are at greater risk for comorbidities that may increase adverse outcomes for this population when they have coronavirus disease 2019 (COVID-19). The study aims are to examine the population-level odds of hospitalisation and mortality of privately insured individuals with COVID-19 with and without IDNDs IDs, controlling for sociodemographics and comorbid health conditions. METHODS: This is a retrospective, cross-sectional study of 1174 individuals with IDs and neurogenetic conditions within a population of 752 237 de-identified, privately insured, US patients diagnosed with COVID-19 between February 2020 and September 2020. Odds of hospitalisation and mortality among COVID-19 patients with IDNDs adjusted for demographic characteristics, Health Resources and Services Administration region, states with Affordable Care Act and number of comorbid health conditions were analysed. RESULTS: Patients with IDNDs overall had higher rates of COVID-19 hospitalisation than those without IDNDs (35.01% vs. 12.65%, P < .0001) and had higher rates of COVID-19 mortality than those without IDNDs (4.94% vs. .88%, P < .0001). Adjusting for sociodemographic factors only, the odds of being hospitalised for COVID-19 associated with IDNDs was 4.05 [95% confidence interval (CI) 3.56-4.61]. Adjusting for sociodemographic factors and comorbidity count, the odds of hospitalisation for COVID-19 associated with IDNDs was 1.42 (95% CI 1.25-1.61). The odds of mortality from COVID-19 for individuals with IDNDs adjusted for sociodemographic factors only was 4.65 (95% CI 3.47-6.24). The odds of mortality from COVID-19 for patients with IDNDs adjusted for sociodemographic factors and comorbidity count was 2.70 (95% CI 2.03-3.60). A major finding of the study was that even when considering the different demographic structure and generally higher disease burden of patients with IDNDs, having a IDND was an independent risk factor for increased hospitalisation and mortality compared with patients without IDNDs. CONCLUSIONS: Individuals with IDNDs had significantly higher odds of hospitalisation and mortality after adjusting for sociodemographics. Results remained significant with a slight attenuation after adjusting for sociodemographics and comorbidities. Adjustments for comorbidity count demonstrated a dose-response increase in odds of both hospitalisation and mortality, illustrating the cumulative effect of health concerns on COVID-19 outcomes. Together, findings highlight that individuals with IDNDs experience vulnerability for negative COVID-19 health outcomes with implications for access to comprehensive healthcare.

Modified Glasgow prognostic score (mGPS) is correlated with sarcopenia and dominates the prognostic role of baseline body composition parameters in advanced gastric and esophagogastric junction cancer patients undergoing first-line treatment from the phase III EXPAND trial.

BACKGROUND: Sarcopenia represents an established adverse prognostic factor in cancer patients. Consequently, different means to counteract sarcopenia have been proposed to improve cancer treatment. Computed tomography (CT)-based measurements, also labor intensive, are well validated for the analysis of sarcopenia. As inflammation plays a key role in the development of sarcopenia, we here studied the role of the modified Glasgow prognostic score (mGPS), consisting of inflammation parameters plasma C-reactive protein (CRP) and albumin, to predicting sarcopenia and adipose tissue-related body composition (BC) parameters at baseline and their changes during treatment and to analyze its prognostic role in conjunction with BC parameters. PATIENTS AND METHODS: CT measurements of BC parameters were carried out at baseline and week 12 in patients with advanced gastric or esophagogastric junction cancer from the phase III EXPAND trial, undergoing first-line platinum-fluoropyrimidine chemotherapy. mGPS was calculated from baseline CRP and albumin plasma levels. Pearson correlation and Cox regression analyses were carried out. RESULTS: mGPS is strongly prognostic for overall survival (OS). Baseline mGPS is significantly correlated with baseline mean muscle attenuation (MA; P < 0.0001). Baseline mGPS did not predict a decline in muscle or adipose tissue parameters during 12 weeks of treatment and a decline in muscle or adipose tissue parameters was not prognostic for OS. MA lost its prognostic role for OS when mGPS or CRP was entered into the Cox models. Eastern Cooperative Oncology Group performance status together with CRP or mGPS remained the sole baseline prognostic factors for OS. CONCLUSIONS: Our findings support a model where tumor-mediated inflammatory response represents a strong prognostic factor, which is causally related to sarcopenia, but with no direct causal path from sarcopenia to survival. Therefore, therapeutic targeting of systemic inflammation should be further explored as a promising strategy to improve both sarcopenia and the efficacy and tolerability of cancer treatment.

Maternal and Child Health Pipeline Training Programs: A Description of Training Across 6 Funded Programs.

PURPOSE: The HRSA-funded maternal and child health pipeline training programs (MCHPTPs) are a response to the critical need to diversify the MCH workforce, as a strategy to reduce health disparities in MCH populations. These MCHPTPs support students from undergraduate to graduate education and ultimately into the MCH workforce. DESCRIPTION: The models and components of training across the six MCHPTPs funded in 2016-2021 are summarized, to examine the design and delivery of undergraduate pipeline training and the insights gained across programs. ASSESSMENT: Strategies that emerged across training programs were organized into three themes: recruitment, support for student persistence (in education), and pipeline-to-workforce intentionality. Support for student persistence included financial support, mentoring, creating opportunity for students to develop a sense of belonging, and the use of research as a tool to promote learning and competitiveness for graduate education. Finally, the link to Maternal and Child Health Bureau (MCHB) long-term training and other MCHB opportunities for professional development contributed significant nuance to the pipeline-to-workforce objectives of these programs. CONCLUSIONS: The MCHPTPs not only increase the diversity of the MCH workforce, they also actively prepare the next generation of MCH leaders. The intentional connection of undergraduates to the infrastructure and continuum of MCH training, underscores the comprehensive impact of this funding.

Expression and prognostic value of transcription factor PROX1 in colorectal cancer.

BACKGROUND: PROX1 is a specific target of the ß-catenin/TCF pathway in the intestinal epithelium. It acts as a regulator of progression from a benign to a highly dysplastic phenotype in colorectal tumours. However, the clinical significance of PROX1 expression is not known. METHODS: We studied the prognostic value of immunohistochemical expression of PROX1 in a series of 517 patients with colorectal cancer (CRC). RESULTS: The majority of the tumour samples expressed PROX1 (91%, 471 out of 517). High PROX1 expression was associated with a poor grade of tumour differentiation (P<0.0001). In the subgroup of patients with colon cancer, high PROX1 expression was associated with unfavourable colorectal cancer-specific survival (CCSS) as compared with low PROX1 expression (CCSS 47% vs 62%; P=0.045; RR 1.47). The association between high PROX1 and poor outcome was further strengthened in female colon cancer patients (CCSS 38% vs 63%; P=0.007; RR 2.02). Nonetheless, in multivariate survival analysis PROX1 expression was not retained as an independent prognostic factor. CONCLUSION: High PROX1 expression is associated with a poor grade of tumour differentiation, and, in colon cancer patients, also with less favourable patient outcome. Our results strengthen the previous preclinical observations that PROX1 has a role in tumour progression in CRC.

Organic labeling influences food valuation and choice.

Everyday we choose between a variety of different food items trying to reach a decision that fits best our needs. These decisions are highly dependent on the context in which the alternatives are presented (e.g. labeling). We investigate the influence of cognition on food evaluation, using an fMRI experiment in which subjects saw and bid on different foods labeled with (or without) a widely known German emblem for organically produced food. Increased activity in the ventral striatum was found for foods labeled "organic" in comparison to conventionally labeled food. Between-subject differences in activity were related to actual everyday consumption behavior of organic food.

Continuous-flux MOVPE growth of position-controlled N-face GaN nanorods and embedded InGaN quantum wells.

We demonstrate the fabrication of N-face GaN nanorods by metal organic vapour phase epitaxy (MOVPE), using continuous-flux conditions. This is in contrast to other approaches reported so far, which have been based on growth modes far off the conventional growth regimes. For position control of nanorods an SiO(2) masking layer with a dense hole pattern on a c-plane sapphire substrate was used. Nanorods with InGaN/GaN heterostructures have been grown catalyst-free. High growth rates up to 25 microm h(-1) were observed and a well-adjusted carrier gas mixture between hydrogen and nitrogen enabled homogeneous nanorod diameters down to 220 nm with aspect ratios of approximately 8:1. The structural quality and defect progression within nanorods were determined by transmission electron microscopy (TEM). Different emission energies for InGaN quantum wells (QWs) could be assigned to different side facets by room temperature cathodoluminescence (CL) measurements.

Mortality of full-term infants during the first month of life in a tertiary care hospital.

OBJECTIVE: The neonatal mortality rate is disproportionately influenced by preterm infants and does not reflect the rate in full-term infants. Our objectives were to estimate the full-term neonatal mortality rate and to identify causes of death in full-term infants during the first month of life. STUDY DESIGN: A retrospective study of full-term infant deaths during a 6-year period from 2000 to 2005, in a tertiary medical center. RESULT: During the study period there were 44,703 full-term births and 31 deaths, representing a mortality rate of 0.69 per 1,000 live births. The main cause of death was congenital anomalies (64.5%), specifically cardiac anomalies. Other causes were chromosomal anomalies or syndromes (12.9%), labor complications (12.9%), infections (3.2%), congenital diseases (3.2%) and metabolic disorders (3.2%). CONCLUSION: The mortality rate of full-term infants may be lower than previous estimates. Efforts aimed at decreasing mortality among full-term infants should focus on prenatal diagnosis.

Decreased xanthine oxidoreductase is a predictor of poor prognosis in early-stage gastric cancer.

BACKGROUND: Xanthine oxidoreductase (XOR) is a key enzyme in the degradation of DNA, RNA and high-energy phosphates. About half of the patients with breast cancer have a decrease in XOR expression. Patients with breast cancer with unfavourable prognosis are independently identified by the loss of XOR. AIM: To assess the clinical relevance of XOR expression in gastric cancer. METHODS: XOR levels were studied by immunohistochemistry in tissue microarray specimens of 337 patients with gastric cancer and the relation between XOR expression and a series of clinicopathological variables, as well as disease-specific survival, was assessed. RESULTS: XOR was moderately decreased in 41% and was undetectable in another 14% of the tumours compared with the corresponding normal tissue. Decreased XOR was associated with advanced stage, deep tumour penetration, diffusely spread tumour location, positive lymph node status, large tumour size, non-curative disease, cellular aneuploidy, high S-phase fraction and high cyclooxygenase-2 expression, but not with p53 expression or Borrmann classification. Down regulation of XOR was associated with unfavourable outcome, and the cumulative 5-year gastric cancer-specific survival in patients with strong XOR expression was 47%, compared with 22% in those with moderate to negative expression (p<0.001). This was also true in patients with stage I-II (p = 0.01) and lymph node-negative (p = 0.02) disease, as well as in patients with smaller (< or =5 cm) tumours (p = 0.02). CONCLUSION: XOR expression in gastric cancer may be a new marker for a more aggressive gastric cancer biology, similar to that previously reported for breast cancer.

The effect of gestational age on neonatal outcome in low-risk singleton term deliveries.

OBJECTIVE: To assess the association between gestational age at delivery and adverse neonatal outcome among term low-risk singleton neonates. METHODS: A retrospective cohort study design was used. The study group included all low-risk singleton term (37 + 0 to 41 + 6 weeks) newborns delivered in a single tertiary university-affiliated medical center over a 5-year period. Outcome of neonates delivered at 37 + 0 to 37 + 6 weeks of gestation (early term) and 41 + 0 to 41 + 6 weeks of gestation (late term) was compared to that of neonates delivered at 39 + 0-39 + 6 weeks of gestation (control). RESULTS: Overall, the outcome of 30 229 neonates was analyzed. The incidence of neonatal mortality was 1.0 per 1000 live-born neonates, with no significant difference between the various gestational age groups. Early term newborns were at higher risk for respiratory morbidity, hypoglycemia, hypocalcemia, thrombocytopenia and unexplained jaundice, and had higher rates of prolonged hospital stay, NICU admission, sepsis workup and antibiotic treatment. On multivariate analysis, early term delivery was an independent predictor for composite respiratory morbidity (OR=2.4, 95% CI 1.6-3.8, p < 0.001), unexplained jaundice (OR=2.1, 95% CI 1.7-2.5, p < 0.001), hypoglycemia (OR=2.5, 95% CI 1.5-4.3, p < 0.001) and NICU admission (OR=1.9, 95% CI 1.5-2.5, p < 0.001). Late term neonates had a significantly higher rate of large for gestational date, but did not differ from controls with respect to the rate of composite neurologic or respiratory complications, NICU admission, birth trauma or infectious morbidity. CONCLUSION: Even in low-risk singleton deliveries, early term is associated with an increased risk of neonatal morbidity.

Repeated intratumoral administration of ONCOS-102 leads to systemic antitumor CD8+ T-cell response and robust cellular and transcriptional immune activation at tumor site in a patient with ovarian cancer.

Adenoviruses are excellent immunotherapeutic agents with a unique ability to prime and boost immune responses. Recombinant adenoviruses cause immunogenic cancer cell death and subsequent release of tumor antigens for antigen presenting cells, resulting in the priming of potent tumor-specific immunity. This effect may be further enhanced by immune-stimulating transgenes expressed by the virus. We report a case of a 38-year-old female with Stage 3 metastatic micropapillary serous carcinoma of the ovary. She was treated in a Phase I study with a granulocyte-macrophage colony stimulating factor (GMCSF)-expressing oncolytic adenovirus, Ad5/3-D24-GMCSF (ONCOS-102). The treatment resulted in progressive infiltration of CD8+ lymphocytes into the tumor and concomitant systemic induction of several tumor-specific CD8+ T-cell populations. The patient was alive at the latest follow up more than 20 months after initiation of the study.

Congenital myopathy with oculo-facial abnormalities (Marden-Walker syndrome).

Marden-Walker syndrome present in the neonatal period is characterized by oculo-facial abnormalities, congenital myopathy, and contractures. A newborn infant with a similar pattern of anomalies is reported, and further evidence for autosomal recessive inheritance as well as new neuropathological findings are included.

Effect of maternal immunization with oral poliovirus vaccine on neonatal immunity.

During the summer of 1988, an outbreak of poliomyelitis caused by poliovirus 1 occurred in Israel, during which a national mass immunization campaign with oral poliovirus was undertaken. This prospective study was undertaken to assess the effect of maternal oral poliovirus immunization during the third trimester of pregnancy on neonatal immunity against poliovirus. Cord blood specimens of 88 neonates, born 2 to 7 weeks after maternal immunization, were examined for antipoliovirus antibodies and compared with 100 samples obtained from neonates 7 months before the outbreak. Blood samples were also obtained from the 62 mothers of neonates who had been immunized 2 to 5 weeks before delivery. Sera were tested for neutralizing antibodies to the 3 poliovirus types using a microneutralization technique. The geometric mean titer to poliovirus type 1 was significantly higher in neonates whose mothers were immunized during pregnancy (87.1) than in the offspring of the nonvaccinated group (53.0), P < 0.05. Two to 3 weeks after immunization, geometric mean titers against all 3 poliovirus types were higher in maternal blood than in cord blood whereas 4 to 5 weeks after vaccination a significant difference was found for type 3 only. Although oral poliovirus immunization during pregnancy resulted in higher neonatal antibody titers to poliovirus type 1, the proportion of newborns with titers of < 1:8 to the 3 poliovirus types did not change significantly.

Mycetoma of the renal pelvis caused by Fusarium species.

A preterm infant, with posterior urethral valves had a mycetoma of the renal pelvis caused by Fusarium species. Prolonged treatment with amphotericin B alone or with flucytosine failed. Combined surgical drainage and medical therapy resulted in full resolution.

Metastasis of chondrosarcoma.

This study was undertaken to analyse metastases of patients with intermediate- or high-grade chondrosarcomas. Out of 24 intermediate-grade tumours, 5 (21%) developed metastases, as did 6 of 10 high-grade tumors (60%) (P = 0.04). Four patients developed pulmonary metastasis only, 5 developed both pulmonary metastasis and metastases of the other sites. Two patients showed a rare metastatic pattern: bone metastases only. The metastasis rate in the primary chondrosarcoma (42%) was higher than that in the secondary chondrosarcomas (0%) (P = 0.03). The metastasis rate was higher in patients with local recurrence (86%) than in those without local recurrence (19%) (P = 0.01). In 5 of 6 patients who had a local relapse and metastasis, the interval between the two relapses was a few months.

An oral zinc loading test in psoriasis.

Changes of zinc in body fluids were evaluated in 12 patients with extensive psoriasis and compared with those of 11 healthy volunteers, using an oral zinc loading test. Plasma zinc levels and urinary zinc excretion were measured by atomic absorption spectrophotometry. No significant difference was found between plasma zinc levels and urinary zinc excretion following an overnight fast. Both groups showed extensive increases in urinary zinc excretion following the loading test. The peak levels of plasma zinc were significantly lower in the psoriatic patients two and four hours after zinc ingestion (P less than .01 and P less than .02, respectively).

Serum macro creatine kinase type 2 in asphyxiated newborn infants.

The presence of macro creatine kinase type 2 (MCK2) activity was noted in the serum of seven out of 32 newborn infants with perinatal asphyxia or birth trauma. MCK2 isoenzyme, when present, represented 15-35% of the total creatine kinase (CK) activity. The clinical and biochemical features of the seven MCK2-positive and 25 MCK2-negative newborns were compared. The infants with MCK2 activity were all males and clinically appeared to be more severely injured, requiring longer hospitalization. Total CK activity was similar in the two groups and CK-MB and CK-BB isoenzyme fractions were present in a similar proportion of infants in both groups. Two infants in each group had long-term neurological disorders. Although the presence of MCK2 has been noted in adult patients with end-stage metastatic solid tumors, the presence of this isoenzyme has not previously been reported in newborn infants.

Risk factors associated with candidaemia in the neonatal intensive care unit: a case-control study.

The incidence of candidaemia is steadily increasing in neonatal intensive care units (NICUs). Several neonatal risk factors for candidaemia have been identified, however, the number of cases in controlled studies is small and knowledge concerning maternal and perinatal risk factors is limited. The present study attempted to identify modifiable, independent maternal, perinatal and neonatal risk factors for candidaemia using a retrospective case-control study in the NICU of a tertiary-care paediatric medical centre. The study group consisted of 56 neonates admitted to the NICU between 1996 and 2000 who acquired candidaemia. The control group comprised the first infant admitted immediately after each study infant matched for gestational age (+/-10 days) and birthweight (+/-200 g). Potential maternal, perinatal and neonatal risk factors were compared between the groups using statistical methods and analysed by univariate and multivariate stepwise logistic regression models. The independent risk factors found to be significantly associated with increased risk of candidaemia were duration of ventilation and presence of bacteraemia before candidaemia. Maternal steroids had a significant protective effect. The positive predictive value using these three parameters was 78.38%. Maximizing in-utero steroid treatment in high-risk pregnancies, minimizing the days of mechanical ventilation and investment of efforts in prevention of bacteraemia may help to reduce the incidence of candidaemia in the NICU.

Controlled trial of immune response of preterm infants to recombinant hepatitis B and inactivated poliovirus vaccines administered simultaneously shortly after birth.

AIM: The study was conducted to evaluate the immunogenicity of an early, extra dose of enhanced inactivated poliovirus vaccine (IPV) administered simultaneously with recombinant hepatitis B vaccine (HBV) to preterm infants shortly after birth. METHODS: Three groups were studied. Fifty preterm infants received IPV intramuscularly within 24 hours of birth, in addition to routine recommended childhood immunisations. Fifty two preterm infants and 35 full term infants received routine immunisations only (routine vaccination timing: HBV at birth, 1 and 6 months of age; IPV at 2 and 4 months; oral polio vaccine (OPV) at 4 and 6 months; diphtheria-tetanus-pertussis (DTP) at 2, 4, and 6 months; and Haemophilus influenzae B vaccine at 2 and 4 months). Blood samples were taken at birth, 3 and 7 months of age from all infants, and at 1 month of age from preterm infants only. RESULTS: At birth, a lower percentage of both study and control preterm infants had antipoliovirus type 3 titres >/= 1:8 than full term infants. At 1 and 3 months of age significantly more early IPV infants had antipoliovirus type 3 titres >/= 1:8 than routinely vaccinated preterm infants (p < 0.05). At 7 months of age there were no significant differences in percentage of antipoliovirus titres >/= 1:8 or geometric mean times (GMTs) between the early IPV group and the routinely vaccinated preterm group. At 3 and 7 months of age, the percentage of positive antihepatitis B titres (>/= 1:10) and the GMT of the early IPV preterm group did not differ significantly from those of preterm controls. There was no significant difference in percentage of positive antihepatitis B titres between the early IPV group and full term controls at any time. GMTs for hepatitis B antibodies were significantly lower in the early IPV preterm group than in full term controls at 3 and 7 months of age. CONCLUSIONS: Administration of an additional dose of IPV simultaneously with routine HBV to preterm infants shortly after birth provides early protection from poliovirus and hepatitis B infection, and does not interfere with poliovirus antibody production at the age of 7 months.

Iodine and hypothyroidism in neonates with congenital heart disease.

AIM: To evaluate the influence of the intravenous injection of iodine during cardiac catheterisation, and of topical iodine antiseptics during surgical procedures, on thyroid function in full term neonates. METHODS: Twenty one full term infants with major cardiac anomalies who survived for more than a month were studied. Thyroxine and thyrotropin concentrations were measured (by radioimmunoassay) before each procedure, 24 hours after the procedure, and every week thereafter until the age of 1 month or until normal. Thyroxine values less than 64.4 nmol/l were considered low, while thyrotropin values greater than 30 mU/l were considered high. RESULTS: Thyroid function tests before iodine exposure were within normal limits in all infants. Following catheterisation or surgery six infants had raised thyrotropin concentrations; three had low thyroxine concentrations. Two of those infants were treated with L-thyroxine. CONCLUSION: Iodine exposure during cardiac catheterisation or surgery may induce transient hypothyroidism in term infants.
