ABSTRACT

This study uses Landsat 5, 7, and 8 level 2 collection 2 surface temperature to examine habitat suitability conditions spanning 1985-2019, relative to the thermal tolerance of the endemic and endangered delta smelt (Hypomesus transpacificus) and two non-native fish, the largemouth bass (Micropterus salmoides) and Mississippi silverside (Menidia beryllina) in the upper San Francisco Estuary. This product was validated using thermal radiometer data collected from 2008 to 2019 from a validation site on a platform in the Salton Sea (RMSE = 0.78 °C, r = 0.99, R2 = 0.99, p < 0.01, and n = 237). Thermally unsuitable habitat, indicated by annual maximum water surface temperatures exceeding critical thermal maximum temperatures for each species, increased by 1.5 km2 yr-1 for the delta smelt with an inverse relationship to the delta smelt abundance index from the California Department of Fish and Wildlife (r = -0.44, R2 = 0.2, p < 0.01). Quantile and Theil-Sen regression showed that the delta smelt are unable to thrive when the thermally unsuitable habitat exceeds 107 km2. A habitat unsuitable for the delta smelt but survivable for the non-natives is expanding by 0.82 km2 yr-1. Warming waters in the San Francisco Estuary are reducing the available habitat for the delta smelt.

ABSTRACT

Adult Mesenchymal Stem Cells (MSCs) have a well-established tumor-homing capacity, highlighting potential as tumor-targeted delivery vehicles. MSCs secrete extracellular vesicle (EV)-encapsulated microRNAs, which play a role in intercellular communication. The aim of this study was to characterize a potential tumor suppressor microRNA, miR-379, and engineer MSCs to secrete EVs enriched with miR-379 for in vivo therapy of breast cancer. miR-379 expression was significantly reduced in lymph node metastases compared to primary tumor tissue from the same patients. A significant reduction in the rate of tumor formation and growth in vivo was observed in T47D breast cancer cells stably expressing miR-379. In more aggressive HER2-amplified HCC-1954 cells, HCC-379 and HCC-NTC tumor growth rate in vivo was similar, but increased tumor necrosis was observed in HCC-379 tumors. In response to elevated miR-379, COX-2 mRNA and protein was also significantly reduced in vitro and in vivo. MSCs were successfully engineered to secrete EVs enriched with miR-379, with the majority found to be of the appropriate size and morphology of exosomal EVs. Administration of MSC-379 or MSC-NTC cells, or EVs derived from either cell population, resulted in no adverse effects in vivo. While MSC-379 cells did not impact tumor growth, systemic administration of cell-free EVs enriched with miR-379 was demonstrated to have a therapeutic effect. The data presented support miR-379 as a potent tumor suppressor in breast cancer, mediated in part through regulation of COX-2. Exploiting the tumor-homing capacity of MSCs while engineering the cells to secrete EVs enriched with miR-379 holds exciting potential as an innovative therapy for metastatic breast cancer.

ABSTRACT

Ambient seismic noise is characterized by randomness incurred by the random position and strength of the noise sources as well as the heterogeneous properties of the medium through which it propagates. Here we use ambient noise data recorded prior to the 1996 Gjálp eruption in Iceland in order to show that a reduction of noise randomness can be a clear short-term precursor to volcanic activity. The eruption was preceded on 29 September 1996 by a Mw ~5.6 earthquake that occurred in the caldera rim of the Bárdarbunga volcano. A significant reduction of randomness started occurring 8 days before the earthquake and 10 days before the onset of the eruption. This reduction was observed even at stations more than 100 km away from the eruption site. Randomness increased to its previous levels 160 minutes after the Bárdarbunga earthquake, during which time aftershocks migrated from the Bárdarbunga caldera to a site near the Gjálp eruption fissure. We attribute this precursory reduction of randomness to the lack of higher frequencies (>1 Hz) in the noise wavefield caused by high absorption losses as hot magma ascended in the upper crust.

ABSTRACT

OBJECTIVE: This paper describes the results of a bi-level intervention, using a cognitive-behavioral theoretical approach, to improve the oral hygiene of older adults and the disabled in community-based low income senior housing. METHODS: The bi-level pilot intervention consisted of an on-site tailored adapted motivational interviewing (AMI) session and two oral health fairs, supported by a resident campaign committee, to change community norms. All materials were available in English and Spanish. Participants completed a survey consisting of 12 domains that provided the basis for tailoring the AMI and shaping the campaigns. The domains were activities of daily living (ADLs), access to oral health information, oral hygiene status, dental knowledge, hygiene behaviors, importance of oral hygiene, self-efficacy/locus of control, diet, intentions, self-management worries/fears, perceived risk and dry mouth. MAIN OUTCOME MEASURES: Each participant received clinical assessments consisting of full-mouth plaque score (PS) and gingival index (GI) before the intervention and at three months. RESULTS: Twenty-seven residents with at least one tooth completed all phases of the study. The mean number of domains requiring attention was 4.5 (SD 1.6) with a range of one to seven. Mean baseline PS was 83% (SD 16%) which improved significantly to 58% (SD 31%); mean baseline GI was 1.15 (SD 0.61) and improved significantly to 0.49 (SD 0.46). CONCLUSIONS: This pilot study supports the feasibility and acceptability of a tailored oral hygiene intervention among older and disabled adults living in low income senior housing. Although a small sample, the study demonstrated significant improvements in both plaque and gingival scores three months after the bi-level intervention.

ABSTRACT

OBJECTIVE: To examine if wound aetiology has an effect on the pain-relieving properties of an ibuprofen-releasing foam dressing, which was previously shown to reduce pain in wounds of various aetiologies, compared with local best practice (LBP). METHOD: This was a secondary analysis of data from a multicentre, randomised, parallel group trial of patients with painful exuding wounds of various aetiologies. Wound aetiology was determined at enrolment. Of 853 patients enrolled into the trial, 688 belonged to a wound aetiology subgroup that included >25 patients and were included in the analysis reported here. Patients were randomised to a dressing containing 112.5mg of ibuprofen (ibuprofen foam) or to LBP for 5 days. Patients recorded pain relief and pain intensity daily. The main endpoint was the proportion of patients who, from day 1 to day 5, reported a summed pain relief score >50% of the total maximum pain relief score (TOTPARD5>50%) and the corresponding number needed to treat (NNT) for each wound aetiology subgroup. Further analyses included the proportion of patients who, on a daily basis, reported pain relief >50% of the maximum daily pain relief, the proportion of patients who, on day 5, experienced a reduction in pain intensity of >50% of the maximum score (PIDD5>50%), and if PIDD5>50% was related to baseline pain intensity. RESULTS: Patients were categorised by the following five wound types: arterial, venous, and mixed arterial-venous leg ulcers, vasculitis and traumatic ulcers. The ibuprofen foam dressing was associated with significantly greater pain relief than LBP in all different wound aetiology subgroups, whether chronic or traumatic (acute). Overall, TOTPARD5>50% was 55% in the ibuprofen foam group and 24% in the LBP group (p<0.0001; NNT, 3.2). The pain intensity evaluations revealed similar results in favour of ibuprofen foam compared with LBP. No correlation was observed between PIDD5>50 and initial pain intensity. CONCLUSION: In this study, the ibuprofen foam dressing was shown to consistently relieve wound pain in exuding wounds of various aetiologies, irrespective of basal pain intensity. The data suggest that local pain relief by an ibuprofen foam dressing is possible in the most common, painful, exuding, chronic and acute/traumatic wounds and so is a safer alternative to systemic pain treatment.

ABSTRACT

In patients undergoing chemoradiotherapy for esophageal cancer, the inability to eat may severely impair nutritional status. We conducted a retrospective study to compare the efficacy of the Polyflex self-expanding silicone stent (PS) versus a jejunostomy tube (JT) for maintaining nutrition during neoadjuvant chemoradiation therapy in patients with esophageal cancer who were scheduled for resectional surgery. Thirty-six patients were treated either with PS placement (12 patients) or JT placement (24 patients) prior to receiving an 8-week course of chemoradiation therapy. Patients were interviewed weekly until cessation of therapy. Patient data were collected on procedural success and complication rates, nutritional status, and dysphagia scores. PS placement was successful in 11 of 12 patients (92%), and those 11 patients were able to resume oral nutrition. Dysphagia scores improved from a mean of 3 to 1 in the PS group (P < 0.005) but did not change significantly in the JT group. PS were removed endoscopically without complications prior to the esophagectomies. Albumin levels and weight increased significantly in both the PS and JT groups. There were no significant differences between groups in the procedural success rates (PS 92% vs. JT 100%, P = 0.33), complication rates (PS 22% vs. JT 4%, P = 0.11), mean increase in weight (PS 4.4 kg vs. JT 4.2 kg, P = 0.59), and mean increase in serum albumin (PS 0.62 g/dL vs. JT 0.44 g/dL, P = 0.05). PS is a safe and effective alternative to a surgical JT for maintaining nutrition in this subset of patients.

ABSTRACT

We determined the influence of the triazole derivatives paclobutrazol, penconazole, epixiconazole, propiconazole and myclobutanil on the drought tolerance and post drought recovery of container-grown horse chestnut (Aesculus hippocastanum L.) saplings. Myclobutanil neither conferred drought resistance, as assessed by its effects on a number of physiological and biochemical parameters, nor affected growth parameters measured after recovery from drought. Chlorophyll fluorescence (F(v)/F(m)), photosynthetic rates, total foliar chlorophyll and carotenoid concentrations, foliar proline concentration and superoxide dismutase and catalase activities were consistently higher and leaf necrosis and cellular electrolyte leakage was lower at the end of a 3-week drought in trees treated with paclobutrazol, penconazole, epixiconazole or propiconazole than in control trees. Twelve weeks after drought treatment, leaf area and shoot, root and total plant dry masses were greater in triazole-treated trees than in control trees with the exception of those treated with myclobutanil. In a separate study, trees were subjected to a 2-week drought and then sprayed with paclobutrazol, penconazole, epixiconazole, propiconazole or myclobutanil. Chlorophyll fluorescence, photosynthetic rate, foliar chlorophyll concentration and catalase activity over the following 12 weeks were 20 to 50% higher in triazole-treated trees than in control trees. At the end of the 12-week recovery period, leaf area and shoot, root and total plant dry masses were higher in triazole-treated trees than in control trees, with the exception of trees treated with myclobutanil. Application of triazole derivatives, with the exception of myclobutanil, enhanced tolerance to prolonged drought and, when applied after a 2-week drought, hastened recovery from drought. The magnitude of treatment effects was in the order epixiconazole approximately propiconazole > penconazole > paclobutrazol > myclobutanil.

ABSTRACT

Breast augmentation and breast reconstruction, either immediate or delayed, are increasingly common operations. All radiologists need to be able to recognize the normal appearances of the more commonly used implants on various imaging modalities, and breast radiologists in particular are facing new challenges when imaging the women involved. This article aims to review the normal and abnormal findings in women who have had breast augmentation and reconstruction, including implant insertion and reconstruction by autologous myocutaneous flaps.

ABSTRACT

We have assessed whether an epidural steroid injection is effective in the treatment of symptoms due to compression of a nerve root in the lumbar spine by carrying out a prospective, randomised, controlled trial in which patients received either an epidural steroid injection or an intramuscular injection of local anaesthetic and steroid. We assessed a total of 93 patients according to the Oxford pain chart and the Oswestry disability index and followed up for a minimum of two years. All the patients had been categorised as potential candidates for surgery. There was a significant reduction in pain early on in those having an epidural steroid injection but no difference in the long term between the two groups. The rate of subsequent operation in the groups was similar.

ABSTRACT

Quantitative trait loci (QTL) for growth traits and water-use efficiency have been identified in two water regimes (normal and drought-treated) and for a treatment index. A tetraploid hybrid F2 population originating from a cross between a Salix dasyclados clone (SW901290) and a Salix viminalis clone ('Jorunn') was used in the study. The growth response of each individual including both above and below ground dry-matter production (i.e. shoot length, shoot diameter, aboveground and root dry weight, internode length, root dry weight/total dry weight, relative growth rate and leaf nitrogen content) was analysed in a replicated block experiment with two water treatments. A composite interval mapping approach was used to estimate number of QTL, the magnitude of the QTL and their position on genetic linkage maps. QTL specific for each treatment and for the treatment index were found, but QTL common across the treatments and the treatment index were also detected. Each QTL explained from 8% to 29% of the phenotypic variation, depending on trait and treatment. Clusters of QTL for different traits were mapped close to each other at several linkage groups, indicating either a common genetic base or tightly linked QTL. Common QTL identified between treatments and treatment index in the complex trait dry weight can be useful tools in the breeding and selection for drought stress tolerance in Salix.

ABSTRACT

The Adelaide and Meath Hospital (AMNCH) is a new hospital, with the respiratory service established in 1999. We report on our experience with lung cancer in this short time. We conducted a retrospective chart audit, identifying patients from the Oncology Nurse patient list, of lung cancer cases diagnosed in 2001-2002. In 2001, 47 cases were diagnosed, with 71 cases diagnosed in 2002. Time to tissue diagnosis was 14.8, 2-46 (mean, range, one subject skewing the data) days. Diagnosis by tissue type was as follows: non-small cell carcinoma (NSCLC) n=92 (77.9%), small cell lung carcinoma (SCLC) n=17 (14.4%), mesothelioma n=2 (17%), carcinoid n=1 (0.8%) and no tissue diagnosis n=6 (5.1%). Staging of NSCLC: stage 1a n=3 (3.2%), stage 1b n=6 (6.5%), stage 2a n=5 (5.4%), stage 2b n=2 (2.2%), stage 3a n=10 (10.9%), stage 3b n=22 (23.9%) and stage 4 n=44 (47.8%). Staging of SCLC: limited stage n=5 (29.4%), extensive stage n=12 (70.6%). Positive emission tomography (PET) was employed in the staging of 22 patients. In these patients PET up-staged the disease in 8 patients, and management was unchanged in 8 patients. We conclude that 1. the relatively new respiratory service in AMNCH is handling increasing numbers of lung cancer cases, 2. cases are diagnosed within an acceptable time-frame, 3. rate of tissue diagnosis is comparable to national figures, 4. most patients present with advanced disease and 5. PET is a useful imaging modality for detection of cancer spread in selected patients.

ABSTRACT

BACKGROUND: Accuracy of predictive formulae is crucial for therapeutic planning because indirect calorimetry measurement is not always possible or cost effective. Energy requirements are more difficult to predict in the acutely ill obese patient compared with lean patients because of an increased resting energy expenditure per lean body mass and a variable stress response to illness. METHODS: A retrospective review of 726 patients identified 57 patients (32 spontaneous breathing, S; 25 ventilator dependent, V) with body mass indexes of 30-50 kg/m2. Limits-of-agreement analysis determined bias (the mean difference between measured and predicted values) and precision (the standard deviation of the bias) to evaluate the accuracy of predictive formulae compared with measured resting energy expenditure (MREE) by a Deltatrac Metabolic Monitor. Predictive accuracy was determined within+/-10% MREE. The predictive formulae examined were: variations of the Harris-Benedict equations using ideal, adjusted weights of 25% and 50% and actual weights with stress factors ranging from 1.0 to 1.5; the Ireton-Jones equation for obesity; the Ireton-Jones equations for hospitalized patients (S and V); and the ratio of 21 kcalories per kilogram actual weight. RESULTS: The mean MREE was 21 kcal/kg actual weight. The adjusted Harris-Benedict average weight equation was optimal for predicting MREE for the combined S and V sets (bias = 182+/-123; 67%+/-10% MREE), as well as the S subset (bias = 159+/-112; 69%+/-10% MREE). CONCLUSIONS: The Harris-Benedict equations using the average of actual and ideal weight and a stress factor of 1.3 most accurately predicted MREE in acutely ill, obese patients with BMIs of 30-50 kg/m2. Predictive formulae were least accurate for obese, ventilator-dependent patients.

ABSTRACT

Paroxysmal trigeminal neuralgia and atypical facial pain are both fairly common conditions that produce pain in the face of different character. Trigeminal neuralgia is sharp and shooting, brought on by facial movement, change of temperature and by touching the face at a specific point (the trigger point). Atypical facial pain is dull and unrelenting and its site is ill-defined. Trigeminal neuralgia is generally more common in older people, and affects women slightly more than men, and atypical facial pain generally affects younger people, with women predominating. The pains should never be confused. We have noticed that many patients with trigeminal neuralgia have additional symptoms of atypical facial pain and so we reviewed the records of the Pain Relief Unit retrospectively. Of the 83 patients identified with trigeminal neuralgia where records were adequate, 35 (42%) also had atypical facial pain. Five of these had developed it before the onset of trigeminal neuralgia and could be examples of pretrigeminal neuralgia. There were eight patients in the series with multiple sclerosis, of whom two also had atypical facial pain. There seemed to be no relationship between the development of atypical facial pain and the interventions used to treat trigeminal neuralgia. It is important that both conditions are identified and treated individually.

ABSTRACT

A prospective study was conducted to assess the prevalence, severity and diagnostic utility of pain in patients with venous leg ulcers. A semi-structured questionnaire was completed by 140 consecutive patients in two specialist centres caring for patients with leg ulcers. A high proportion (64%) of the 94 patients with ulcers of purely venous aetiology reported severe pain; 50% of these patients were taking either mild analgesia or none at all. In 10 of 72 cases, leg elevation made the pain worse. Venous ulcers are painful. Pain in three distinct locations was reported by patients-within ulcers, around ulcers and elsewhere in the leg. The presence of severe pain does not necessarily indicate arterial disease or infection. Pain is, in general, inadequately controlled in these patients.

ABSTRACT

In a randomized, double-blind, double-dummy, single-dose, parallel-group study, oral ibuprofen arginine (400 mg) was compared with intramuscular (i.m.) morphine sulphate (5 or 10 mg) for post-operative pain relief after orthopaedic surgery in 120 patients. The study medication was administered post-operatively at the time when each patient first requested pain relief for moderate to severe pain. Assessment of pain intensity and pain relief was made using standard visual analogue scales and verbal rating scores. In all three groups, there was a reduction in pain compared with baseline, measured by visual analogue scales and verbal rating scores, at all time points up to completion of the study at 240 min. For example, visual analogue scales decreased by 35 (10-52) mm at 1 h in the morphine 5 mg group, 24 (12-39) mm in morphine 10 mg group and 21 (8-38) mm in the ibuprofen arginine group (median and inter-quartile range). Verbal rating scores showed a similar pattern. Comparing the groups over the whole study period using the sum of pain intensity differences showed no significant differences in pain experience between the groups. Assessment of total pain relief also showed no significant differences. The incidence and types of side effect seen were similar in the three groups.

ABSTRACT

In order to determine the degree to which the recommendations of the report of the joint working party on 'Pain after Surgery' by the Royal College of Surgeons of England and the College of Anaesthetists have been implemented, a postal survey was conducted of all hospitals in the United Kingdom where surgery is performed. The number of hospitals with a multidisciplinary acute pain service had significantly increased from 2.8% before September 1990 to 42.7% at the end of 1994. Over the same period there has been an increase in the number of hospitals with a named clinician responsible for acute pain management, from 20 before 1990 to 230 (65.2%) and the number of hospitals with an acute pain nurse has increased from 8 (2.3%) prior to 1990 to 139 (39.3%). Routine assessment of pain and sedation occurs in 82% of hospitals with established acute pain services and in less than 50% of hospitals without an acute pain service. The use of written protocols, the provision of out-of-hours cover and regular training for all staff have increased with time. Research and audit activity related to acute pain management has also improved since 1990.
