The Impact of the COVID-19 Pandemic on Cleft Care.

BACKGROUND: The COVID-19 pandemic had multiple effects on the provision of health care, including the suspension of elective and nonessential surgeries. The objective of this study was to determine the early effect of the COVID-19 pandemic on the surgical care of patients with cleft lip and/or palate at a high-volume cleft center. METHODS: A retrospective comparative cohort study of patients with cleft lip and/or palate undergoing lip adhesion, cleft lip and nose repair, and palatoplasty before and during the pandemic was conducted. There were 50 patients in the prepandemic cohort and 53 in the pandemic cohort. RESULTS: Mean age at lip adhesion was 3.1 ± 1.1 months prepandemic (n = 8) and 3.5 ± 2.5 months in the pandemic cohort (n = 8) (P = 0.75). One lip adhesion was delayed by 1.6 months. Mean age at cleft lip and nose repair was 6.6 ± 1.9 months prepandemic (n = 23) and 8.0 ± 2.1 months in the pandemic cohort (n = 23) (P = 0.03). Six pandemic cleft lip and nose repairs were delayed; the mean delay was 2.6 ± 1.8 months. The mean age at palatoplasty was 13.9 ± 2.2 months prepandemic (n = 26) and 14.1 ± 2.9 months in the pandemic cohort (n = 26) (P = 0.79). Seven pandemic palatoplasties were delayed; the mean delay was 3.3 ± 1.4 months. CONCLUSIONS: The COVID-19 pandemic caused delays at each stage of repair for cleft lip and/or palate-related procedures; however, only cleft lip and nose repair were significantly affected. This study emphasizes the importance of remaining vigilant regarding the care of this vulnerable population during this challenging time.

Age-Related Differences in Psychosocial Function of Children with Craniofacial Anomalies.

BACKGROUND: Age is a frequent consideration for surgical timing in pediatric craniofacial surgery for optimal psychosocial development. However, systematic evaluations of the effects of age in children under active treatment have not been thoroughly evaluated. METHODS: Ninety-nine patients (age, 8 to 17 years; 46.5 percent male) from the University of California, Los Angeles, Craniofacial Clinic were prospectively evaluated using the Pediatric Patient-Reported Outcomes Measurement Information System to assess anger, anxiety, depression, and quality of peer relationships. Patients were stratified into three age groups by years: group A, 8 to 10 years, n = 30; group B, 11 to 13 years, n = 41; and group C, 14 to 17 years, n = 28. Analyses of variance and logistic regression analyses were performed. RESULTS: Significant differences in anxiety (F2,96 = 5.1; p = 0.008), depression (F2,96 = 9.7; p < 0.001), peer relationships (F2,96 = 3.5; p = 0.03), and anger (F2,96 = 4.9; p = 0.009) were found among the age groups. Group A demonstrated the highest anxiety, highest depression, and lowest peer relationship scores overall. Although there were no differences in anger between groups A and C, group B had the lowest anger scores. Children with poor scores of higher severity, defined as greater than 1 SD worse than the national mean, were compared. Group A contributed the highest percentages of more severely affected children in all categories. A logistic regression analysis demonstrated that group A was a statistically significant predictor for scores of higher severity in both anxiety (OR, 3.8; 95 percent CI, 1.3 to 11.5; p = 0.02) and peer relationships (OR, 3.4; 95 percent CI, 1.3 to 9.3; p = 0.02). CONCLUSIONS: Children between 8 and 10 years of age with craniofacial anomalies constitute a high-risk subset for psychosocial dysfunction. The authors' work suggests that tight surveillance with family and school awareness may be necessary for this age group. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

Identification of matrix metalloproteinase-9 in amniotic fluid and amniochorion in spontaneous labor and after experimental intrauterine infection or interleukin-1 beta infusion in pregnant rhesus monkeys.

OBJECTIVE: The purpose of this study was to examine the roles of intrauterine infection, inflammation, and spontaneous labor on the expression of matrix metalloproteinase-9 in fetal membranes and amniotic fluid of late pregnant rhesus monkeys. STUDY DESIGN: Pregnant rhesus monkeys with timed gestations were chronically catheterized to allow serial sampling of amniotic fluid before and during experimentally induced intrauterine inflammation. Six animals received group B streptococci into the chorionic-decidual space, and 4 animals received intra-amniotic interleukin-1 beta infusions (10 microg). Three additional animals were serially sampled by amniocentesis through late pregnancy until spontaneous term labor. Amniotic fluid samples were examined by zymography for matrix metalloproteinase-9 and -2 and Western immunoblot for matrix metalloproteinase-9 and -2 and tissue inhibitors of metalloproteinase-1 and -2. Fetal membranes were obtained at cesarean delivery during labor (before rupture), formalin fixed, and embedded in paraffin for immunocytochemistry of matrix metalloproteinase-9 and in situ hybridization of matrix metalloproteinase-9 messenger RNA. Tissues from 2 additional animals were collected as age-matched non-labor controls. RESULTS: In amniotic fluid, the 92-kd latent matrix metalloproteinase-9 was detectable in late pregnancy and increased dramatically, followed by the appearance of the 83-kd active form before spontaneous term delivery. Amniotic fluid matrix metalloproteinase-2 levels (both latent and active forms) remained relatively constant throughout pregnancy and in labor. Both bacteria and interleukin-1 beta rapidly increased the signal of latent matrix metalloproteinase-9 without a consistent increase in the active form before the onset of labor. Chorionic-decidual inoculation of group B streptococci was followed by the expression of latent matrix metalloproteinase-9 before the appearance of group B streptococci in amniotic fluid or the onset of labor. Matrix metalloproteinase-2 increased to a new steady-state level or remained unchanged after group B streptococci inoculation or interleukin-1 beta infusion, respectively. Amniotic fluid tissue inhibitors of metalloproteinase-1 declined and tissue inhibitors of metalloproteinase-2 remained unchanged during early group B streptococci infection, after interleukin-1 beta infusion and on the day of spontaneous term labor. However, both tissue inhibitors of metalloproteinase-1 and -2 levels increased after preterm labor that was induced by group B streptococci. Immunocytochemistry localized matrix metalloproteinase-9 protein to amnion and chorion epithelial and mesenchymal cells and decidual stromal cells. Granular matrix metalloproteinase-9 staining was observed in the connective tissue layer of inflamed fetal membranes. In situ hybridization for messenger RNA confirmed the production of matrix metalloproteinase-9 by amnion and chorion. CONCLUSION: Bacterial- and interleukin-1 beta-induced preterm labor and spontaneous term labor are preceded and accompanied by progressive increases in amniotic fluid matrix metalloproteinase-9 (92 kd) in rhesus monkeys. Amniotic fluid matrix metalloproteinase-9 may serve as a clinical marker for the onset of both preterm and term labor.

An instrument to measure musculoskeletal symptoms among immigrant Hispanic farmworkers: validation in the nursery industry.

We report on the construction and psychometrics of a survey measure of musculoskeletal symptomatology for use with Spanish-speaking immigrant farmworkers. Survey development included focus groups with workers, forward and backward translations, and pilot testing. The final survey includes a body diagram and items about symptom severity, frequency, and duration and about self-treatment, medical care, and job tasks. We report on the initial test of the survey with 213 commercial nursery workers in Southern California. Fifty-five percent of the workers reported pain, with 30% reporting back pain, 21% reporting upper extremity pain, 19% reporting lower extremity pain, and 10% reporting neck and shoulder pain. A composite symptom score exhibited acceptable test-retest reliability (r = 0.41, p < 0.01) over the annual agricultural cycle. Greater symptomatology was associated with greater frequency of self-treatment (r = 0.42, p < 0.01), seeking professional health care (t = 2.49, p < 0.05), and exposure to high-risk jobs (OR = 2.1, p < 0.05, CI = 1.0 to 4.4), supporting the validity of composite score.

Quantification of the glycolytic origin of plasma glycerol: implications for the use of the rate of appearance of plasma glycerol as an index of lipolysis in vivo.

To assess whether plasma glycerol could be directly derived from plasma glucose, nine postabsorptive dogs were infused with [U-14C] glucose and [2-3H] glycerol to measure the rates of appearance of plasma glucose and glycerol and the conversion of plasma glucose to glycerol before (basal) and after two hours of infusion of glucose (45 mumol/kg/min). Basally (plasma glucose 4.9 +/- 0.2 mmol/L; plasma insulin 5.9 +/- 0.2 microU/mL), rates of appearance of plasma glucose and glycerol were 20 +/- 2 and 5.9 +/- 1.3 mumol/kg/min, respectively, and 1.6 +/- 0.6% of plasma glycerol was derived from plasma glucose. After glucose infusion (plasma glucose 9.1 +/- 0.7 mmol/L; plasma insulin 21.1 +/- 1.9 microU/mL), the rate of appearance of plasma glycerol decreased 80% to 1.1 +/- 0.3 mumol/kg/min and the percent of plasma glycerol from glucose increased significantly to 6.9 +/- 2.9. However, the absolute rate of conversion of glucose to glycerol did not change (0.09 +/- 0.03 v 0.07 +/- 0.03 mumol/kg/min). We conclude that even under conditions of stimulated glycolysis and inhibited lipolysis, only a small amount of plasma glycerol is derived from plasma glucose. Thus, rates of appearance of plasma glycerol can be used as a measure of rates of overall lipolysis in vivo.

Selenium status during recovery from malnutrition: effects of selenium supplementation - abstract

It was previously shown that malnourished Jamaican children often had evidence of selenium deficiency, viz. low erythrocyte glutathione peroxidase (RBC GSH Px) activity that correlated inversely with cardiothoracic ratio, and was particularly low in children who died. In this study, RBC GSH Px activity, plasma GSH Px activity and plasma selenium concentration were measured in 41 malnourished children on admission to hospital, and after recovery in weight-for-height. Plasma GSH Px activity and selenium concentrations were also measured longitudinally throughout recovery in a group of 24 initially selenium-deficient children, 17 of whom were given oral selenium supplements for the first 3 weeks. RBC GSH Px activity was low in all malnourished children, whether oedematous or not (Table). It did not change with recovery. Plasma GSH Px activity and plasma selenium concentration were low only in oedematous malnourished children. PEM GROUPS: control, marasmus, oedematous; ERYTHROCYTE GSH Px (U/gHb)- *36ñ2, 24ñ4, 21ñ3 respectively; PLASMA GSH Px act. (U/L) - 140ñ9, 142ñ15, 98ñ8 respectively, PLASMA SE CONCN. (æg/e) - 86ñ4, 76ñ12, 53ñ5. *meanñSEM. Selenium was associated with a rapid rise in both plasma GSH Px activity and plasma selenium concentration. The increase in plasma selenium was more dramatic (44 up to 144 æg/e in 6 days): the variability in plasma GSH Px activity was much greater, and they remained within the control range. The changes were sustained after supplementation ceased. We conclude that (1) selenium deficiency in malnourished Jamaican children is not reversed during 'recovery' on the conventional 'high energy' diet, (2) plasma selenium concentration responds rapidly to changes in selenium intake, and is a useful measure of selenium status, and (3) oral selenium supplements improve selenium status in children recovering from malnutrition (AU)

Genetic linkage studies with cleft lip and palate: report of two family studies.

Genetic linkage studies are reported on two families with cleft lip +/- cleft palate. For the first family (LP01) the etiology of the clefting is unknown, and the linkage analyses were done assuming both autosomal dominant and autosomal recessive inheritance. Close linkage is rejected with the Duffy blood group under the dominant model and with four loci (Duffy, Kidd, and ABO blood groups and haptoglobin) under the recessive model. The second family (LP02) is a Mexican-American family segregating the van der Woude syndrome with lip pits. The linkage analyses for this autosomal dominant trait excluded close linkage with seven genetic markers, including three on chromosome one. The maximum lod scores were 0.6 with BF (chromosome 6) and 0.4 with the P blood group, which is not yet mapped.

A prospective study of the effects of ultralow volume (ULV) aerial application of malathion on epidemic Plasmodium falciparum malaria. III. Ecologic aspects.

The effects of aerial ultralow volume (ULV) malathion on selected species of nontarget animals in Haiti are reported. Mortality of certain groups of insects such as bees, flies, beetles, and butterflies was observed immediately following spray application. Minor fish mortality occurred only in shallow water exposed to direct spray. The brain acetylcholine esterase levels of living fish, tree lizards, birds and bats collected from treated areas were not significantly reduced. No ill or dead animals, besides the few fish, were seen even when maximum exposure occurred. Only minor changes in the feeding behavior of some insectivorous birds were observed. The relative bird density decreased substantially for only one species during the study, and other factors besides treatment were considered to be the reasons for the decline. Aerial applications of ULV malathion at dosages sufficient to dramatically reduce anopheline populations did not significantly affect nontarget vertebrates in this tropical environment.

Field study of the safety of abate for treating potable water and observations on the effectiveness of a control programme involving both abate and malathion.

Abate is a larvicide for Aedes aegypti, a vector of yellow fever, dengue, and haemorrhagic fever. It is less toxic than malathion or DDT. Tests in human volunteers had previously indicated it would be safe to add to drinking-water where the mosquito often breeds.In a 19-month test in Puerto Rico, Abate was added to the drums and cisterns in which a community of about 2000 persons stored their drinking-water. This use of Abate and other insecticidal measures (malathion spraying) gradually achieved control of A. aegypti during the first 4 months of treatment and control was maintained thereafter although the test area was surrounded by active breeding-sites. There was no accumulation of Abate in the water in spite of monthly additions of the compound. With minor exceptions, residents readily accepted this use of Abate. Careful surveillance failed to reveal any illness or significant side-effects attributable to measures adopted in the control programme. Abate is considered safe for full-scale field use according to directions.
