The impact of SEOM–IAS (Scientific Exploitation of Operational Missions–Improved Atmospheric Spectroscopy) spectroscopic information on CO columns from TROPOMI (Tropospheric Monitoring Instrument) shortwave infrared (SWIR) observations was examined. HITRAN 2016 (High Resolution Transmission) and GEISA 2015 (Gestion et Etude des Informations Spectroscopiques Atmosphériques 2015) were used as a reference upon which the spectral fitting residuals, retrieval errors and inferred quantities were assessed. It was found that SEOM–IAS significantly improves the quality of the CO retrieval by reducing the residuals to TROPOMI observations. The magnitude of the impact is dependent on the climatological region and spectroscopic reference used. The difference in the CO columns was found to be rather small, although discrepancies reveal, for selected scenes, in particular, for observations with elevated molecular concentrations. A brief comparison to Total Column Carbon Observing Network (TCCON) and Network for the Detection of Atmospheric Composition Change (NDACC) also demonstrated that both spectroscopies cause similar columns; however, the smaller retrieval errors in the SEOM with Speed-Dependent Rautian and line-Mixing (SDRM) inferred CO turned out to be beneficial in the comparison of post-processed mole fractions with ground-based references.

High-quality observations have indicated the need for improved molecular spectroscopy for accurate atmospheric characterization. Line data provided by the new SEOM-IAS (Scientific Exploitation of Operational Missions—Improved Atmospheric Spectroscopy) database in the shortwave infrared (SWIR) region were used to retrieve CO total vertical columns from a selected set of nadir SCIAMACHY (SCanning Imaging Absorption SpectroMeter for Atmospheric CHartographY) observations. In order to assess the quality of the retrieval results, differences in the spectral fitting residuals with respect to the HITRAN 2016 (High-resolution TRANsmission molecular absorption) and GEISA 2015 (Gestion et Etude des Informations Spectroscopiques Atmosphériques) line lists were quantified and column-averaged dry-air CO mole fractions were compared to NDACC (Network for the Detection of Atmospheric Composition Change) and TCCON (Total Carbon Column Observing Network) ground-based measurements. In general, it was found that using SEOM-IAS line data with corresponding line models improve the spectral quality of the retrieval (smaller residuals) and increase the fitted CO columns, thereby reducing the bias to both ground-based networks.

Objective Explore the impact of personalized nursing services and hospice care on the quality of life of elderly patients with advanced cancer. Method We selected 80 elderly cancer patients admitted to our hospital from September 2020 to May 2021, and divided these patients into a study group and a control group using a random number table method. The patients in the control group used conventional nursing methods to treat and care for the patients, and the patients in the study group used hospice care measures and combined personalized nursing measures. The quality of life and pain treatment effects of the two groups of patients before and after treatment were compared. Result Before treatment, the quality-of-life scores of the two groups of patients were low, and there was no statistical difference (P>0.05); After treatment, the quality of life of the two groups of patients improved, but compared with the control group, the improvement was more obvious in the study group, and the difference was statistically significant (P<0.05). In terms of pain treatment effect, the total effective rate of pain treatment in the study group was 87.5%, which was significantly better than the 62.5% in the control group. The difference was statistically significant (P<0.05). Conclusion Personalized nursing services and hospice care are conducive to improving the survival and treatment of elderly patients with advanced cancer, and can be used as a clinical application program for the care of advanced cancer patients.

Background. Patients (pts) diagnosed with congestive heart failure (HF) have been reported to have more frequent depression and worsened health related quality of life (HRQOL). Although depression is more common in women than men in this condition, the impact of HF on depression and HRQOL in men versus women is unclear. We sought to examine the relationship between pt sex, HF diagnosis, and pt-perceived depression and HRQOL. Methods. Depression (PHQ-9) and HRQOL (EQ5D) data were collected using tablet computers from pts presenting for routine outpatient cardiovascular assessment at our institution between November, 2010 and December, 2011. Demographic, clinical, and historical data was collected as per routine. We examined the association of pt sex and clinical diagnosis of HF with instrument results after adjusting for potential confounding information using mutliple linear regression. Results. Of 3046 pts (age 61±15), 39% were female and 8.7% were diagnosed with HF. Overall, PHQ-9 was greater, and minor or major depression (PHQ-9≥10) was more frequent, in women than men (4.6±4.6 vs. 3.3±4.4; 14.0% vs. 8.9%, both p<0.05) and in HF pts than pts without HF (5.9±5.6 vs. 3.6±4.3, 22.0% versus 9.6%; both p<0.05). Similarly, HRQOL was worse in women than men (EQ-5D 0.80±0.18 vs. 0.87±0.16; p<0.01) and in HF pts than no HF (EQ-5D 0.76±0.18 vs. 0.85±0.17; p<0.01). However, the difference in PHQ-9 between pts with versus without HF was greater in men (6.23±6.06 vs. 3.02±4.06, p<0.01) than women (5.43±4.85 vs. 4.55±4.58, p=0.09). After adjusting for cardiovascular diagnoses, comorbidities, clinical and demographic data, multivariable modeling of PHQ-9 revealed a significant interaction between pt sex and HF diagnosis (p=0.001; see Figure) such that women had greater PHQ-9 scores compared to men without HF, but in the setting of HF, mens' PHQ-9 scores were greater. Modeling of EQ-5D also revealed that after risk-adjustment an interaction between HF diagnosis and sex was present with a similar pattern of findings. Conclusion. Although depression is more frequent and severe in women compared to men, and in pts with versus without HF, HF appears to impact depression severity more in men compared to women.

Abstract. Airborne observations of greenhouse gases are a very useful reference for validation of satellite-based column-averaged dry air mole fraction data. However, since the aircraft data are available only up to about 9–13 km altitude, these profiles do not fully represent the depth of the atmosphere observed by satellites and therefore need to be extended synthetically into the stratosphere. In the near future, observations of CO2 and CH4 made from passenger aircraft are expected to be available through the In-Service Aircraft for a Global Observing System (IAGOS) project. In this study, we analyse three different data sources that are available for the stratospheric extension of aircraft profiles by comparing the error introduced by each of them into the total column and provide recommendations regarding the best approach. First, we analyse CH4 fields from two different models of atmospheric composition – the European Centre for Medium-Range Weather Forecasts (ECMWF) Integrated Forecasting System for Composition (C-IFS) and the TOMCAT/SLIMCAT 3-D chemical transport model. Secondly, we consider scenarios that simulate the effect of using CH4 climatologies such as those based on balloons or satellite limb soundings. Thirdly, we assess the impact of using a priori profiles used in the satellite retrievals for the stratospheric part of the total column. We find that the models considered in this study have a better estimation of the stratospheric CH4 as compared to the climatology-based data and the satellite a priori profiles. Both the C-IFS and TOMCAT models have a bias of about −9 ppb at the locations where tropospheric vertical profiles will be measured by IAGOS. The C-IFS model, however, has a lower random error (6.5 ppb) than TOMCAT (12.8 ppb). These values are well within the minimum desired accuracy and precision of satellite total column XCH4 retrievals (10 and 34 ppb, respectively). In comparison, the a priori profile from the University of Leicester Greenhouse Gases Observing Satellite (GOSAT) Proxy XCH4 retrieval and climatology-based data introduce larger random errors in the total column, being limited in spatial coverage and temporal variability. Furthermore, we find that the bias in the models varies with latitude and season. Therefore, applying appropriate bias correction to the model fields before using them for profile extension is expected to further decrease the error contributed by the stratospheric part of the profile to the total column.

Background. Psoriasis is a chronic, inflammatory, and multifactorial dermatosis that impairs quality of life (QoL). Health-related QoL has become an important element in medical decision-making along with the effectiveness and the harmlessness of the treatments. Objective. To assess the impact of psoriasis in the QoL of patients with psoriasis by using the DLQI scales. Methods. A cross-sectional study from January to June 2018 was conducted in the Department of Dermatology of the University Hospital Joseph Raseta Befelatanana, Antananarivo, Madagascar, including patients more than 18 years old with mild to severe psoriasis. The severity of psoriasis was assessed using the “Psoriasis Area and Severity Index (PASI)”. QoL of patients with psoriasis was evaluated by using the DLQI scales. Results. 80 patients were included, their mean age was 36.5 years, and the male to female was 1.5 : 1. The mean DLQI score was 13.8. Symptoms, feelings, and psychic were the most altered dimensions. QoL was impaired in young patients, single, having medium level education. Even though patients with disease duration more than 5 years had higher DLQI score than other patients, the difference was not statistically significant (p=0.36). Furthermore, the clinical presentation of psoriasis did not influence the patient’s QoL (p=0.73). Patients with nail involvement had QoL impaired but the difference with another localization was not statistically significant (p=0.2). The quality of life was influenced by body area involved. The higher the body surface area involved, the more QoL is impaired (p=0.002). Furthermore, the higher the PASI, the more QoL is altered (p=0.002). Conclusion. Psoriasis has a negative impact in the quality of life in Malagasy patients with psoriasis, especially in younger and single patients. Worse quality of life is correlated to severity of psoriasis.

Objective To assess whether radiofrequency volumetric tissue reduction of the palate can improve patients’ snoring symptoms and quality of life. Methods A prospective cross-sectional study was undertaken. Over an 18-month period, consecutive habitual snorers without sleep apnoea were asked to complete a validated Snoring Symptoms Inventory (SSI) questionnaire before and 3–6 months after radiofrequency surgical treatment. It contained 25 questions on the impact of snoring symptoms, including social, work, physical and emotional aspects. Most patients underwent 2 operations (Somnoplasty® Somnus device) with a 2-month interval. A scale of 0 (no snoring) to 10(extremely loud snoring) was used to assess partners’ perception of the snoring intensity. Paired T-test was used to compare the mean difference in the SSI before and after surgery. Partners’ scores were analysed with Wilcoxon signed ranks test. Results 26 patients (19 male, 7 female) aged between 33 and 74 (mean=48) were recruited. Preoperative BMI scores ranged from 19 to 35 (mean=28). Pre- and postoperative mean SSI scores were 60.5 (SD 12.3) and 42.8 (SD 17.4). The difference between the 2 means is 17.6 (95% Confidence Interval, 11.0 to 24.2), P<0.0001. The median for pre- and postoperative partners’ scores is 10 and 5 respectively. and the difference is statistically significant (P<0.0001). Conclusions Radiofrequency volumetric tissue reduction can improve habitual snorers’ snoring symptoms, snoring-related quality of life, and partner's perception of their snoring. Long-term results of this procedure need to be ascertained with further studies.

Completeness Of Reporting

Abstract Background Preprint usage is growing rapidly in the life sciences; however, questions remain on the relative quality of preprints when compared to published articles. An objective dimension of quality that is readily measurable is completeness of reporting, as transparency can improve the reader’s ability to independently interpret data and reproduce findings. Methods In this observational study, we initially compared independent samples of articles published in bioRxiv and in PubMed-indexed journals in 2016 using a quality of reporting questionnaire. After that, we performed paired comparisons between preprints from bioRxiv to their own peer-reviewed versions in journals. Results Peer-reviewed articles had, on average, higher quality of reporting than preprints, although the difference was small, with absolute differences of 5.0% [95% CI 1.4, 8.6] and 4.7% [95% CI 2.4, 7.0] of reported items in the independent samples and paired sample comparison, respectively. There were larger differences favoring peer-reviewed articles in subjective ratings of how clearly titles and abstracts presented the main findings and how easy it was to locate relevant reporting information. Changes in reporting from preprints to peer-reviewed versions did not correlate with the impact factor of the publication venue or with the time lag from bioRxiv to journal publication. Conclusions Our results suggest that, on average, publication in a peer-reviewed journal is associated with improvement in quality of reporting. They also show that quality of reporting in preprints in the life sciences is within a similar range as that of peer-reviewed articles, albeit slightly lower on average, supporting the idea that preprints should be considered valid scientific contributions.

AbstractThis study explored the impact of contextualized practice on second language (L2) learners’ production of wh-questions in the L2 classroom. It examined the quality of practice (correct vs. incorrect production) and the contribution of declarative knowledge to proceduralization. Thirty-four university-level English as a foreign language learners first completed a declarative knowledge test. Then, they engaged in various communicative activities over five weeks. Their production of wh-questions was coded for accuracy (absence of errors) and fluency (speech rate, mean length of pauses, and repair phenomena). Improvement was measured as the difference between the first and last practice sessions. The results showed that accuracy, speech rate, and pauses improved but with distinct patterns. Regression models showed that declarative knowledge did not predict accuracy or fluency; however, declarative knowledge assisted the learners to engage in targetlike behaviors at the initial stage of proceduralization. Furthermore, whereas production of accurate wh-questions predicted accuracy improvement, it had no impact on fluency.
