ABSTRACT

BACKGROUND: This study aims to describe outcomes of posteriorly-placed glaucoma drainage devices (GDD) with concurrent endoscopic vitrectomy in pediatric patients with glaucoma and corneal opacification. METHODS: This retrospective case series identified patients under 18 years of age who underwent posteriorly-placed GDD implantation with concurrent endoscopic vitrectomy between 2012 and 2021. Data collected included ocular diagnoses, prior intraocular surgeries, type and position of GDD, surgical complications, and additional surgeries. Preoperative and final visual acuity, intraocular pressure (IOP), number of glaucoma medications, and exam findings were also recorded. Surgical data included type and position of GDD, Success was defined as IOP between 5-21 mmHg without visually devastating complication or need for additional glaucoma surgery. RESULTS: Ten patients (14 eyes) with sclerocornea (6), Peters Anomaly (4), corneal decompensation from increased IOP (3), and corneal scar (1) underwent combined endoscopic vitrectomy with posteriorly-placed GDD (Baerveldt (10 eyes), Ahmed (4 eyes)) at 4.6 ± 5.8 years of age. Four eyes of 3 patients remained successful at final follow-up, while 10 eyes of 7 patients required 2.4 ± 1.3 additional surgeries for glaucoma (7) or hypotony (3). Kaplan Meier analysis demonstrated 1- and 2-year survival rates of 36% and 18%, respectively. At final follow-up (3.7 ± 2.4 years), after an average of 4.4 ± 2.4 glaucoma surgeries, 13 of 14 eyes had obtained IOP control on significantly fewer (p<0.0001) IOP-lowering medications. Additional complications included retinal detachment (2), chronic corneal graft failure (2), phthisis (1) and band keratopathy (1). CONCLUSIONS: Management of glaucoma in pediatric eyes with corneal opacification is challenging and often requires multiple surgeries. A combined endoscopic vitrectomy and posteriorly placed GDD is a viable technique to establish aqueous humor outflow. Although the success rate is low, this surgical approach may be useful in ultimately obtaining IOP control and preserving vision in these complex eyes.

ABSTRACT

BACKGROUND: The topical corticosteroid halobetasol propionate (HP) and the retinoid tazarotene (TAZ) are effective in psoriasis treatment. To mitigate adverse cutaneous reactions observed with monotherapy, a fixed- combination HP 0.01%/TAZ 0.045% lotion has been developed for the treatment of plaque psoriasis in adults. OBJECTIVES: To investigate the long-term safety, efficacy and maintenance of response with HP/TAZ lotion. METHODS: This was a 1-year, multicentre, open-label study in 555 adults with psoriasis [Investigator's Global Assessment (IGA) score of 3 ('moderate') or 4 ('severe') and body surface area (BSA) of 3-12% at baseline]. HP/TAZ was administered once daily for 8 weeks and then intermittently as needed in 4-week intervals for up to 1 year based on achievement of treatment success [IGA score of 0 ('clear') or 1 ('almost clear')]. Maximum continuous exposure was 24 weeks. RESULTS: Of 550 participants with postbaseline safety data, 318 (57.8%) achieved treatment success during the study. Of those, 54.4% achieved treatment success within the first 8 weeks; retreatment was not required for >4 weeks in over half (55.3%), and 6.6% did not require any retreatment. Among participants enrolled for the full 52 weeks, 77.5% maintained BSA ≤5% on treatment. There were marked improvements in severity of itching, dryness and burning/stinging over the study course. The most common treatment-related adverse events were application site reactions of dermatitis, pruritus, pain and irritation. CONCLUSIONS: Fixed-combination HP/TAZ lotion provided maintained efficacy with a favourable tolerability and safety profile, supporting its use for the long-term treatment and management of moderate-to-severe plaque psoriasis.

ABSTRACT

BACKGROUND: Brodalumab is efficacious for the treatment of moderate-to-severe plaque psoriasis through 52 weeks. OBJECTIVES: To evaluate the efficacy and safety of brodalumab through 120 weeks, including following withdrawal and retreatment. METHODS: At baseline, patients were randomized to brodalumab (n = 222) or placebo (n = 220). At week 12, patients achieving a static Physician's Global Assessment (sPGA) score of 0 or 1 (sPGA 0/1) with brodalumab were rerandomized to brodalumab (n = 83) or placebo (n = 84; later re-treated with brodalumab if sPGA ≥ 3 occurred), and patients receiving placebo switched to brodalumab (n = 208). Safety was assessed by exposure-adjusted rates of treatment-emergent adverse events. RESULTS: Among those who achieved sPGA 0/1 at week 12 and were rerandomized to brodalumab, 96% and 80% using observed data, respectively, and 74% and 61% using nonresponder imputation, respectively, achieved 75% improvement in Psoriasis Area and Severity Index (PASI 75) and PASI 100 at week 120. Following withdrawal from brodalumab, return of disease occurred after a mean ± SD duration of 74·7 ± 50·5 days. Among those who switched from brodalumab to placebo at week 12, PASI 75 rates using observed data and nonresponder imputation were 55% and 51% at week 20, respectively and 94% and 75% at week 120, respectively; PASI 100 rates at week 120 were 75% and 60%, respectively. Efficacy was maintained through week 120 in those receiving brodalumab after placebo. No new safety signals were observed. CONCLUSIONS: These findings indicate that brodalumab is efficacious and safe for continuous long-term treatment of psoriasis, and support the potential for response after discontinuation and retreatment.

ABSTRACT

The role that physical attractiveness and fluctuating asymmetry (FA), a measure of developmental instability, play in self-perception and peer associations were explored in a well-studied cohort of Jamaican children using a novel research paradigm where subjects were already known to each other for extensive periods of time. The results showed that how attractive a child was perceived by others was significantly positively correlated with self-ratings of attractiveness. Contrary to findings from WEIRD (Western, Educated, Industrialized, Rich, Democratic) samples, the study found a reversal in the sex differences in self-perceived attractiveness and self-esteem, where Jamaican females rate themselves more attractive and report higher self-esteem than do males. Attractiveness also predicts overall popularity, as measured by desirability as a friend and the percentage of peers who choose an individual as a friend. Attractive individuals of both sexes were chosen more often as 'friends'. A significant correlation was also found between an individual's FA and the average FA of those chosen as friends. However, the effect was primarily due to preferences by males for female friends possessing similar levels of FA, which could be an effective strategy in reducing future mating effort.

ABSTRACT

BACKGROUND: Obesity is associated with psoriasis and negatively affects response to therapy. OBJECTIVES: To evaluate the efficacy and safety of brodalumab in nonobese vs. obese patients with psoriasis. METHODS: This is a post hoc analysis of the prospective, phase III, multicentre, randomized, placebo- and active-comparator-controlled AMAGINE-2 and AMAGINE-3 trials, in which patients were randomized to treatment with brodalumab 210 mg every 2 weeks, ustekinumab or placebo for a 12-week induction phase. At week 12, patients who received brodalumab 210 mg every 2 weeks continued brodalumab, those treated with ustekinumab continued ustekinumab, and those who received placebo switched to brodalumab 210 mg every 2 weeks. Patients were categorized by body mass index (BMI) category (< 30 or ≥ 30 kg m-2 ) and efficacy was evaluated using the physician-rated Psoriasis Area and Severity Index and static Physician's Global Assessment instruments. RESULTS: In total, 281 of 687 patients (40·9%) were obese. Skin clearance was comparable across BMI subgroups in brodalumab-treated patients. Psoriasis Area and Severity Index 100% improvement rates in nonobese and obese patients at week 12 were 54·1% and 49·5%, respectively, and at week 52 they were 72·6% and 64·8%, respectively. Week 12 ustekinumab responses were lower than brodalumab responses and were 6-17% lower in obese than in nonobese patients. No appreciable differences in overall safety were observed between nonobese and obese patients. CONCLUSIONS: The efficacy and safety of brodalumab did not differ between patients with moderate-to-severe psoriasis who had a BMI < 30 kg m-2 or a BMI ≥ 30 kg m-2 .

ABSTRACT

AIMS: To study the impact of glycaemic control on urinary incontinence in women who participated in the Diabetes Control and Complications Trial (DCCT; 1983-1993) and its observational follow-up study, the Epidemiology of Diabetes Interventions and Complications (EDIC; 1994-present). METHODS: Study participants were women who completed, at both years 10 (2003) and 17 (2010) of the EDIC follow-up, the urological assessment questionnaire (UroEDIC). Urinary incontinence was defined as self-reported involuntary leakage of urine that occurred at least weekly. Incident urinary incontinence was defined as weekly urinary incontinence present at EDIC year 17 but not at EDIC year 10. Multivariable regression models were used to examine the association of incident urinary incontinence with comorbid prevalent conditions and glycaemic control (mean HbA1c over the first 10 years of EDIC). RESULTS: A total of 64 (15.3%) women with Type 1 diabetes (mean age 43.6 ± 6.3 years at EDIC year 10) reported incident urinary incontinence at EDIC year 17. When adjusted for clinical covariates (including age, DCCT cohort assignment, DCCT treatment arm, BMI, insulin dosage, parity, hysterectomy, autonomic neuropathy and urinary tract infection in the last year), the mean EDIC HbA1c was associated with increased odds of incident urinary incontinence (odds ratio 1.03, 95% CI 1.01-1.06 per mmol/mol increase; odds ratio 1.41, 95% CI 1.07-1.89 per % HbA1c increase). CONCLUSIONS: Incident urinary incontinence was associated with higher HbA1c levels in women with Type 1 diabetes, independent of other recognized risk factors. These results suggest the potential for women to modify their risk of urinary incontinence with improved glycaemic control. (Clinical Trials Registry no: NCT00360815 and NCT00360893).

ABSTRACT

OBJECTIVE: To study MRI and positron emission tomography (PET)/CT imaging of osteoradionecrosis (ORN) of the subaxial cervical spine, a serious long-term complication of radiation therapy (RT) for head and neck cancers that can lead to pain, vertebral instability, myelopathy and cord compression. METHODS: This is a single-institution retrospective review of patients diagnosed and treated for ORN of the subaxial cervical spine following surgery and radiation for head and neck cancer. RESULTS: We report PET/CT imaging and MRI for four patients, each with extensive treatment for recurrent head and neck cancer. Osteomyelitis (OM) and discitis are the end-stage manifestations of ORN of the subaxial spine. CONCLUSION: ORN of the subaxial spine has variable imaging appearance and needs to be differentiated from recurrent or metastatic disease. Surgical violation of the posterior pharyngeal wall on top of the compromised vasculature in patients treated heavily with RT may pre-dispose the subaxial cervical vertebrae to ORN, with possible resultant OM and discitis. MRI and PET/CT imaging are complimentary in this setting. PET/CT images may be misinterpreted in view of the history of head and neck cancer. MRI should be utilized for definitive diagnosis of OM and discitis in view of its imaging specificity. ADVANCES IN KNOWLEDGE: We identify the end-stage manifestation of ORN in the sub-axial spine on PET/CT and MRI to facilitate its correct diagnosis.

ABSTRACT

Surgical resection in oral cancer patients can result in altered speech, swallowing, and patient perception of quality of life (QOL). Oral surgery can result in reduced lingual range of motion (ROM). However, few studies have quantified the degree of lingual restriction after surgery. This pilot study describes a new measurement system to define tongue ROM in surgically treated tongue cancer patients. This measurement system was validated by comparing results in these treated surgical patients versus healthy individuals. This scale was further validated by correlating ROM with performance status, oral outcomes, and patient-rated QOL. Thirty-six patients who underwent oral tongue surgery and 31 healthy individuals were included. Tongue ROM was assessed using a novel ROM assessment system. This novel system was examined in these patients versus healthy subjects. This measurement tool was further validated by correlating tongue ROM in treated patients with performance status, oral outcomes, and patient-rated QOL. Tongue ROM was found to be significantly lower in the surgically treated patients than in the healthy individuals (p = 0.0001). Tongue ROM correlated with performance status, oral outcomes, and all QOL measures. This new tongue ROM measurement system defined tongue deficits in surgically treated oral cancer patients. This tool was validated by comparing results to those in healthy individuals, as well as by correlating tongue ROM to performance status, oral outcomes, and QOL. This measurement tool can be used to define baseline and postsurgery tongue ROM in oral cancer patients, as well as track change over time with recovery and therapy. Future studies should examine use of this measurement tool with other populations demonstrating tongue deficits.

ABSTRACT

Concomitant chemoradiotherapy provides organ preservation for those patients with head and neck cancer. We report the results of a prospective study that examined functional outcomes and quality of life (QOL) after chemoradiotherapy over the first 6 months post-treatment (tx). Twenty-nine patients with head and neck cancer were treated with chemoradiotherapy. All were seen baseline and 3 and 6 months post-tx. Assessments included the performance status scale (PSS), Karnofsky performance status scale, tongue strength, jaw opening, and saliva weight. QOL was patient-rated using the eating assessment tool (EAT-10), MD Anderson dysphagia inventory, speech handicap index (SHI), and the EORTC H&N35 scale. Repeated-measures ANOVAs were used, with significance at p < 0.05. PSS scores were significantly different across time points. Tongue strength, jaw range of motion (ROM), and saliva weight were significantly lower at 3 and 6 months than at baseline. QOL was significantly worse after tx, although it improved by 6 months as rated with the EAT-10 and the SHI scores were significantly worse at 3 and 6 months. EORTC domains of swallowing, senses, speech, dry mouth, and sticky saliva were significantly worse at 3 and 6 months. Concomitant chemoradiotherapy for treatment of head and neck tumors can result in impaired performance outcomes and QOL over the first 6 months post-tx. However, performance status, tongue strength, jaw ROM, and eating QOL were only mildly impaired by 6 months post-tx. Saliva production and speech QOL remained significantly impaired at 6 months post-treatment. Current studies are examining outcomes at 12 and 24 months post-treatment to better predict outcomes over time in this population.

ABSTRACT

Single-crystalline perovskite LaBaCo2O5.5+δ thin films were grown on a (110) NdGaO3 single-crystal substrate in order to systematically investigate the effect of lattice mismatch on the electrical transport properties in comparison to the films on LaAlO3, SrTiO3, and MgO substrates. Microstructure studies reveal that all of the LaBaCo2O5.5+δ films are of excellent quality with atomically sharp interface structures. The electrical and magnetic transport property studies indicate that the resistivity, magnetoresistance, and magnetic moment of the film are very sensitive to the substrate materials because of the lattice mismatch/interface strain. The Curie temperature, however, is almost independent of the strain imposed by the substrate, probably because of the strong coupling between the nanodomain boundary and interface strain.

ABSTRACT

A giant magnetoresistance effect (∼46% at 20 K under 7 T) and anomalous magnetic properties were found in a highly epitaxial double perovskite LaBaCo2O5.5+δ (LBCO) thin film on (001) MgO. Aberration-corrected Electron Microscopy and related analytical techniques were employed to understand the nature of these unusual physical properties. The as-grown film is epitaxial with the c-axis of the LBCO structure lying in the film plane and with an interface relationship given by (100)LBCO || (001)MgO and [001]LBCO || [100]MgO or [010]MgO. Orderly oxygen vacancies were observed by line profile electron energy loss spectroscopy and by atomic resolution imaging. Especially, oxygen vacancy and nanodomain structures were found to have a crucial effect on the electronic transport and magnetic properties.

ABSTRACT

PURPOSE: The purpose of this study was to investigate the incidence of fosaprepitant-associated infusion site adverse events (ISAEs) among a cohort of breast cancer patients receiving doxorubicin/cyclophosphamide (AC) chemotherapy. METHODS: A retrospective review of electronic medical record (EMR) data was performed for all patients who were initiated on AC from January 2011 to April 2012. Data collected included baseline demographics, antiemetic regimen, documentation of ISAEs, and type of intravenous (IV) access. Descriptive statistics (mean and standard deviation or percentages) were summarized overall, by type of IV access and initial antiemetic given. RESULTS: Among the 148 patients included in this analysis, 98 initially received fosaprepitant and 44 received aprepitant. The incidence of ISAEs associated with fosaprepitant administration was 34.7 % (n=34), while the incidence of aprepitant-associated ISAEs was 2.3 % (n=1). All ISAEs were associated with peripheral IV access. The most commonly reported ISAEs were infusion site pain (n=26), erythema (n=22), swelling (n=12), superficial thrombosis (n=8), infusion site hives (n=5), and phlebitis/thrombophlebitis (n=5). Twenty-six patients experienced more than one type of ISAE. CONCLUSIONS: The incidence and severity of ISAEs associated with fosaprepitant administration among a group of patients receiving AC chemotherapy are significant and appreciably higher than what has been previously reported.

ABSTRACT

AIM: Advanced glycation end products (AGEs) and/or their receptors (RAGE) are significantly positively correlated with adiposity, inflammation, dyslipidemia, and insulin resistance in adults. However, the relationships between AGEs, RAGE, and adiposity-related comorbidites in children have not been well studied. METHODS: In a cross-sectional study of 88 children (age 11-15 years) from the New York area enrolled in the Reduce Obesity and Diabetes (ROAD) study, we examined the correlation of the AGE N(ε)-(carboxymethyl)lysine (CML), soluble RAGE (sRAGE), and endogenous secretory RAGE (esRAGE) with adiposity, inflammatory markers [interleukin-6 (IL-6), C-reactive protein, tumor necrosis factor-α], adiponectin, lipids, insulin sensitivity, and insulin secretory capacity. RESULTS: Pediatric CML levels were ~20% below average adult levels. CML was significantly (p < 0.05) positively correlated with age and insulin sensitivity and negatively with adiposity, dyslipidemia and IL-6. sRAGE correlated positively with esRAGE and negatively with adiposity and IL-6. Both sRAGE and esRAGE correlated negatively with insulin secretory capacity. CONCLUSION: Our findings suggest that unlike adults, CML is negatively associated with adiposity and adiposity-related comorbidity risk in children. As in adults, sRAGE and esRAGE were, to varying degrees, negatively correlated with body fatness and risk factors for adiposity-related comorbidities.

ABSTRACT

Packer et al. reported that fenced lion populations attain densities closer to carrying capacity than unfenced populations. However, fenced populations are often maintained above carrying capacity, and most are small. Many more lions are conserved per dollar invested in unfenced ecosystems, which avoid the ecological and economic costs of fencing.

ABSTRACT

Osteoradionecrosis (ORN) of the mandible is a severe complication of radiation therapy for head and neck cancer. In this case series, the authors analyzed their treatment and quality of life outcomes over the past 6 years. A retrospective chart review of 42 patients treated surgically for advanced ORN was conducted. A telephone survey was conducted and quality of life (QOL) questionnaires were completed in a subset of patients. 30 patients responded to the telephone survey assessing QOL for speech, swallowing and overall functioning correlated with oral nutrition and performance status. Surgery for ORN can result in an improved QOL. Functional outcomes of oral intake, speech intelligibility, and eating in public correlated with patient rated QOL measures. A lack of improvement in QOL, despite the restoration of an intact mandible, relates to the persistent effects of chemoradiotherapy.

ABSTRACT

OBJECTIVE: Scapular free flap harvesting for oral cavity cancer reconstruction is an increasingly used and versatile option. We aim to describe the appearance of the scapula harvest site on chest radiograph and CT. METHODS: We retrospectively reviewed a surgical database of 82 patients who underwent scapular osteocutaneous flap harvesting for oral cavity cancer reconstruction and had imaging performed at our institution. We searched the picture archiving and communications system for all associated imaging. RESULTS: Characteristic radiographic appearance in the immediate post-operative period as well as in the remote post-operative period is described, including an upside-down V-shaped paraglenoid notch, rectangular (or triangular) lateral border defects and a sharply pointed inferior scapular body. Additionally, common CT appearances are discussed, including an abrupt gleno-scapular interval, an absent axillary rim bulge and a Z-shaped scapula. CONCLUSION: The altered appearance of the scapular defect following surgical harvest is easily recognised. Although the description of this defect may not alter management and may reasonably be omitted, a radiologist's comfort with these appearances may potentially enhance the understanding of patient management and recognition of superimposed complications, such as infection. ADVANCES IN KNOWLEDGE: Scapular osteocutaneous free flap reconstruction is an increasingly used technique after oral cavity surgery. Very few radiologists reported in our review the surgical scapular defects, and there is apparent ignorance of their appearance. We described characteristic radiographic and CT signs of scapular free flap harvesting to increase radiologists' familiarity with these defects, which may provide clinical information and possibly contribute to detection of complications.

ABSTRACT

Flow cytometry was used to study the genome sizes and ploidy levels for four thrips species: Franklinothrips orizabensis Johansen (Thysanoptera: Aeolothripidae), Frankliniella occidentalis Pergande, Frankliniella fusca Hinds, and Thrips tabaci Lindeman (Thysanoptera: Thripidae). F. orizabensis males and females had 1C genome sizes of 426 Mb and 422 Mb, respectively. Male and female F. fusca had 1C genome sizes of 392 Mb and 409 Mb, whereas F. occidentalis males and females had smaller 1C genomes that were 345 Mb and 337 Mb, respectively. Male F. orizabensis, F. occidentalis and F. fusca were haploid and females diploid. Five isofemale lines of T. tabaci, initiated from parthenogenetic, thelytokous females and collected from different locations in North Carolina, were included in this study; no males were available. One isofemale line was diploid with a genome size of 1C = 310 Mb, and the other four had a mean genome size of 1C = 482 Mb, which is consistent with evidence from microsatellite data of diploidy and polyploidy, respectively, in these same five thelytokous lines.

ABSTRACT

Middle-aged Americans have higher obesity rates than any other age group, yet little is known about age-related changes in central taste function during this critical time. Research on taste and aging has primarily focused on psychophysical responses, and on older adults. Central taste processing in middle-age has not been investigated. In the current study, we compared functional magnetic resonance imaging (fMRI) activation of young and middle-aged adults during hedonic evaluation of a sweet and a bitter taste. A 2 (age group) by 2 (tastant) analysis of variance (ANOVA) on fMRI activation revealed: (1) a main effect of age (young adults>middle-aged adults) in the bilateral anterior cingulate, lentiform nucleus, putamen, caudate, and right precentral gyrus; (2) a main effect of taste (sweet>bitter) in the bilateral pre- and postcentral gyri, anterior cingulate and right middle frontal gyrus; qualified by (3) an age-by-taste interaction. Further inspection of the age-by-taste interaction revealed that there was a significant effect of age (greater activation in young adults) in sensory (insula) and reward (lentiform nucleus) regions during hedonic evaluation of the sweet taste; however, there was no age effect in the bitter taste condition. Further, young adults had greater responses during hedonic evaluation of sucrose than of caffeine in several sensory and motor processing regions (pre- and postcentral gyri, insula), but there were no taste-related differences in activation in the middle-aged adults. We speculate that these results might reflect early age-related differences in central taste processing that occur prior to deficits in gustatory function observed in old age, and this might have important implications for weight changes that occur during middle-age.
