Patient–surgeon sex discordance impacts adverse events but does not affect patient-reported satisfaction after primary total hip arthroplasty: a regional register-based cohort study

Background and purpose The sex of the surgeon has been proposed to be associated with a disparity in clinical outcomes after different surgical procedures. We investigated the association between surgeon–patient sex discordance and adverse events (AEs) and surgical AEs (SAEs) within 90 days after primary total hip arthroplasty (THA). We also investigated patient-reported satisfaction with surgical outcomes 1 year after the surgery. Patients and methods We conducted a register-based cohort study including primary THAs performed due to osteoarthritis between 2008 and 2016 at 10 publicly managed hospitals in western Sweden. Hospital data was linked to the Swedish Arthroplasty Register and a regional patient register. Logistic regression models investigated discordant sex of patients and surgeons on AEs/SAEs and patient-reported satisfaction with the surgical outcome. Results 11,993 primary THAs were included in the study. The proportion of AEs for the concordant group was 7.3% and for the discordant group 6.1%. For SAEs, the proportion was 5.0% for the concordant group and 4.3% for the discordant group. After adjustment the discordant group still had a lower likelihood of an AE or SAE than the concordant group: adjusted odds ratio (aOR) for AE (0.82, 95%CI 0.71–0.95) and for SAE (0.86, CI 0.72–0.99). No association was detected between patient-reported satisfaction and sex discordance. Conclusion Sex discordance between surgeons and patients is linked to a decreased risk of an AE but not a lower level of patient-reported satisfaction with the surgical outcome.
The safety and efficacy of laparoscopic microwave ablation-assisted partial nephrectomy: a new avenue for the treatment of cystic renal tumors

Abstract Purpose Clinically, the management of cystic renal masses is tricky. The study aims to evaluate the safety and efficacy of laparoscopic microwave ablation-assisted partial nephrectomy (LMAPN) for cystic renal tumors. Methods and materials Between November 2017 and January 2022, LMAPN was performed on 43 patients (29 men and 14 women; age range: 22–80 years; median age 54 years) with Bosniak category III (n = 15) or IV (n = 28) cystic renal tumors (size range: 1.2–5.0 cm; mean size 2.8 cm). The median follow-up period was 26 months (range: 7–56 months). Baseline and perioperative data, pathological features, renal function, postoperative complications and oncologic outcomes were collected and evaluated. Results Forty-three cystic renal tumors were successfully managed by LMAPN. The mean operating time was 79 min (range: 40–130 min). The mean time of renal pedicle clamping was 19 min (range: 12–25 min). Mean intraoperative blood loss was 28.4 mL (range: 10–80 mL). The mean postoperative hospitalization duration was 4 days (range: 2–6 days). Negative surgical margins were diagnosed in all cases. During the follow-up, no patient appeared with distant metastasis, wound or peritoneal cavity implantation. No major but minor complications of Clavien–Dindo grade I were encountered after the operation. The 1-, 3- and 4-year overall survival rate was 100%, 96.6% and 88.5%, respectively. Conclusion This is the first study focusing on LMAPN for cystic renal tumors, demonstrating its favorable feasibility, safety and disease control. Long-term follow-up is necessary to draw conclusions on the preference and advantages of the new therapeutic approach.
Discrete Green's function formulation of FDTD method for electromagnetic modelling

The analytical form of the discrete Green's function for the FDTD method is presented as a polynomial function. The FDTD algorithm is re-formulated in terms of a discrete convolution. The new algorithm shows that the FDTD method can be solved avoiding the absorbing boundary conditions (ABCs) and suppressing free space nodes, leading to major savings in computer storage requirements when modelling practical microwave structures.
The ultraviolet spectra of radio-loud and radio-quiet quasars

The rest-frame ultraviolet spectral properties of matched samples of radio-loud, radio-moderate, and radio-quiet quasars are investigated, using quasars drawn from the Large Bright QSO Survey. We confirm the absence of spectral differences between radio-loud and radio-quiet quasars at rest-frame wavelengths longward of 1600 A, as reported by previous authors. However, at shorter wavelengths we find a significant difference: radio-loud quasars have narrower (96% confidence), higher equivalent-width (97% confidence) Lyman-α and C IV emission lines. We further investigate quasars which are radio quiet, but have radio-to-optical flux ratios at the upper extreme of the radio-quiet population. Broad absorption line quasars are overabundant by a factor of ∼ 10 in this radio-moderate population; the overabundance is significant at a 99.99% confidence level
Cotard delusion in a depressed patient: “My throat is missing!”

Cotard's syndrome is a rare neuropsychiatric disorder characterized by marked nihilistic delusions. This report describes an Indonesian woman from a small town in Malaysia who was diagnosed with depression and Cotard's delusion. The diagnosis was confirmed after thorough history‐taking, clinical examination, and relevant laboratory tests. Herein, we highlight the unique psychopathology of a possible Cotard's syndrome subtype and efficacy of pharmacological combination strategies, rather than monotherapy and electroconvulsive therapy, for its treatment.
On the global stability of a temporal discretization scheme for the Navier-Stokes equations

The time discretization by a linear backward Euler scheme for the non-stationary viscous incompressible Navier-Stokes equations with a non-zero external force in a bounded 2D domain with no-slip boundary condition or periodic boundary condition is studied. Improved global stability results are obtained. The boundedness of the solution sequence in V and D(A) norms uniform with respect to At for t E [0, ∞) is proved. A similar result in the V norm was previously obtained by (Geveci, 1989 Math. Comp., 53, 43-53) for the non-forced system. A different approach is used here. As a corollary, the global attractor for the approximation scheme is proved to exist, which is bounded in both V and D(A) spaces, thus compact in both H and V spaces. Applying the same techniques developed here, we are able to improve the main result of (Hill and Suli 2000 IMA J. Numer. Anal., 20, 633-667) by showing that besides the existence of a global attractor, the whole solution sequence is uniformly bounded in V as well, which is of significance from the point of view of computing. As a corollary of local convergence results, upper semi-continuity of the attractor with respect to the numerical perturbation induced by the linear scheme is also established in both H and V spaces. Finally, some preliminary estimates, which are to our knowledge the first of their kind, on the dimensions of the attractors in H and V spaces are also obtained.
Assessment of Livelihood Vulnerability to Climate Change Using Three Index Methods

Vulnerability assessment based on composite indices such as Livelihood Vulnerability Index (LVI) or Sistem Informasi Data Indeks Kerentanan (SIDIK) is widely used, and it is practically known as the initial step to determine the adaptation policies for climate change. Various vulnerability assessment methods that have been developed including LVI and SIDIK raise the possibility that different methods can lead to different conclusions. This research aimed to assess whether the results of vulnerability analysis using different methods on the same data offer consistent results. Comparative studies on this topic based on the different indexing methods may also provide a beneficial insight for stakeholders. We tested LVI, LVI-IPCC, and SIDIK methods in Tanah Merah and Lobuk villages in Sumenep Regency, East Java. We collected the primary data based on interviews with households in the field. Climate data (monthly rainfall, maximum, and minimum air temperature) with 0.05 o spatial resolution from 2001-2020 was obtained from CHIRPS and TerraClimate. Our results showed that both villages were consistently categorized as vulnerable according to LVI, LVI-IPCC, and SIDIK methods. This result is also consistent at village and household levels. The findings showed difference in the key indicators driving the vulnerability in both villages. The key indicators in Tanah Merah Village were households without waste management, training from government, and no early warning system. In contrast, the key indicators driving the vulnerability for Lobuk were households with small land ownership and households with debt. Further, action recommendations for Tanah Merah are providing waste banks and waste sorting facility, upgrading public capacity through workshops, and adopting social media to share climate-related information. For Lobuk, the recommendations are the determination of regulatory instruments related to space utilization in the coastal area, mapping area affected by climate change, and financial literacy improvement especially promoting savings in the community.
Mesoscale Background Error Covariances: Recent Results Obtained with the Limited-Area Model ALADIN over Morocco

Abstract This note presents recent results on the properties of background error covariances computed using the National Meteorological Center (now known as the National Centers for Environmental Prediction) method and applied to a mesoscale limited-area model. The error covariances are computed over a winter period for the Moroccan version of the ALADIN forecast system. The overall results compare well with previous outputs obtained with the same forecast model but on a typical midlatitude domain (viz., ALADIN-France). Thus, the climatological error statistics can be used with an equivalent efficiency in the frame of a 3DVAR analysis system over a wide range of low-latitude and midlatitude limited-area domains. Furthermore, the error statistics between the true forecast fields and the coupling fields for the same domain are compared. The coupling fields are provided by interpolation from the global ARPEGE model. The comparison gives insight into the range of scales over which ALADIN is building its own d.
Effects of mechanical vibration on bone – a critical review

The benefits of reduced treatment time and comfort for patients undergoing corrective dental treatment with devices gave rise to the creation and modification of long-standing treatment protocols. One of the protocols used for these purposes is mechanical vibration. Objective: This review aimed to study the effects of mechanical vibration on bone. Methods: Portal Capes (periodicos.capes.gov.br) database was searched using the keywords “vibration” and “bone” with no date limit. Based on the title and abstract, the first 50 relevant studies were retrieved. The measured frequencies were between 4 and 150 Hz. Regarding exposure time and the number of applications, the variation is so wide that the average or median would not represent a realistic sample pattern. Results: In the retrieved studies, 41 reported improvements in bone conditions. Research studies show that a reproducible protocol is being applied in most studies on the effects of mechanical vibration on bone tissue. Conclusion: There is stimulation of bone biology, regardless of species, in the sense of osteogenesis in individuals exposed to high frequency mechanical vibration. To improve research protocols on the effects of vibrations on the body, more studies are needed.
Next-order structure-function equations

Kolmogorov’s equation [Dokl. Akad. Nauk SSSR 32, 16 (1941)] relates the two-point second- and third-order velocity structure functions and the energy dissipation rate. The analogous next higher-order two-point equation relates the third- and fourth-order velocity structure functions and the structure function of the product of pressure-gradient difference and two factors of velocity difference, denoted Tijk. The equation is simplified on the basis of local isotropy. Laboratory and numerical simulation data are used to evaluate and compare terms in the equation, examine the balance of the equation, and evaluate components of Tijk. Atmospheric surface-layer data are used to evaluate Tijk in the inertial range. Combined with the random sweeping hypothesis, the equation relates components of the fourth-order velocity structure function. Data show the resultant error of this application of random sweeping. The next-order equation constrains the relationships that have been suggested among components of the fou.
Genetic characterization of bovine viral diarrhea virus 1b isolated from mucosal disease

: This report describes a fatal case of mucosal disease in a two-year-old bull. For causal agent detection, scab, whole blood, and feces samples were tested by RT-PCR, PCR, ELISA, and viral isolation. RT-PCR positive amplification was obtained in blood samples for bovine viral diarrhea virus (BVDV). Viral isolation from the scab samples confirmed BVDV as the causative agent of the clinical manifestations. Subsequently, genetic characterization based on phylogenetic analysis of three partial sequences revealed the presence of BVDV subgenotype 1b in analyzed samples. Due to the development of clinical manifestation
N 2 fixation in the Mediterranean Sea related to the composition of the diazotrophic community and impact of dust under present and future environmental conditions

N2 fixation rates were measured in the 0–1000 m layer at 13 stations located in the open western and central Mediterranean Sea (MS) during the PEACETIME cruise (late spring 2017). While the spatial variability in N2 fixation was not related to Fe, P nor N stocks, the surface composition of the diazotrophic community indicated a strong longitudinal gradient increasing eastward for the relative abundance of non-cyanobacterial diazotrophs (NCDs) (mainly γ -Proteobacteria) and conversely decreasing eastward for photo-heterotrophic group A (UCYN-A) (mainly UCYN-A1 and UCYN-A3), as did N2 fixation rates. UCYN-A4 and UCYN-A3 were identified for the first time in the MS. The westernmost station influenced by Atlantic waters and characterized by highest stocks of N and P displayed a patchy distribution of diazotrophic activity with an exceptionally high rate in the euphotic layer of 72.1 nmolNL−1 d−1, which could support up to 19 % of primary production. At this station at 1 %PAR (photosynthetically available radiation) depth, UCYN-A4 represented up to 94 % of the diazotrophic community. These in situ observations of greater relative abundance of UCYN-A at stations with higher nutrient concentrations and dominance of NCDs at more oligotrophic stations suggest that nutrient conditions – even in the nanomolar range – may determine the composition of diazotrophic communities and in turn N2 fixation rates. The impact of Saharan dust deposition on N2 fixation and diazotrophic communities was also investigated, under present and future projected conditions of temperature and pH during short-term (3–4 d) experiments at three stations. New nutrients from simulated dust deposition triggered a significant stimulation of N2 fixation (from 41 % to 565 %). The strongest increase in N2 fixation was observed at the stations dominated by NCDs and did not lead on this short timescale to changes in the diazotrophic community composition. Under projected future conditions, N2 fixation was either increased or unchanged; in that later case this was probably due to a too-low nutrient bioavailability or an increased grazing pressure. The future warming and acidification likely benefited NCDs (Pseudomonas) and Published by Copernicus Publications on behalf of the European Geosciences Union. 416 C. Ridame et al.: N2 fixation in the Mediterranean Sea UCYN-A2, while disadvantaged UCYN-A3 without knowing which effect (alone or in combination) is the driver, especially since we do not know the temperature optima of these species not yet cultivated as well as the effect of acidification.
Two Types of Vertical Electrical Structures in Stratiform Precipitation Regions of Mesoscale Convective Systems

Abstract Electric field (E) soundings in the stratiform regions and transition zones of mesoscale convective systems (MCSs) are reported. Most of the E soundings were made during the 1991 Cooperative Oklahoma Profiler Studies (COPS-91). Multiple E soundings were made in several MCSs. All of the E soundings collected here can be grouped into one of two types. Within each type the soundings and the inferred charge structures are remarkably similar from one place in an MCS to another and from one MCS to another. The charge regions inferred from the E soundings are hundreds of meters thick and have charged densities up to 5.3 nCm−3. Typically, the maximum E in the soundings is about 100 kV m−1. Here, E soundings from three classes of MCSs are discussed. The bow-echo MCSs have simpler vertical charge structures with tour main charge regions, while squall-line MCSs and predominantly stratiform MCSs have five main charge regions. In all of the E soundings there is a substantial region of charge and a large E at .
Estimating and Visualizing Conditional Densities

Abstract We consider the kernel estimator of conditional density and derive its asymptotic bias, variance, and mean-square error. Optimal bandwidths (with respect to integrated mean-square error) are found and it is shown that the convergence rate of the density estimator is order n –2/3. We also note that the conditional mean function obtained from the estimator is equivalent to a kernel smoother. Given the undesirable bias properties of kernel smoothers, we seek a modified conditional density estimator that has mean equivalent to some other nonparametric regression smoother with better bias properties. It is also shown that our modified estimator has smaller mean square error than the standard estimator in some commonly occurring situations. Finally, three graphical methods for visualizing conditional density estimators are discussed and applied to a data set consisting of maximum daily temperatures in Melbourne, Australia.
The Effect of Temporal Overlap on the Perception of Dichotically and Monotically Presented CV Syllables

When stop consonant‐vowel syllables, 390 msec in duration, are presented dichotically, with an onset asynchrony of 50–70 msec, subjects identify the temporally lagging stop more accurately than the leading. When the same pairs are presented monotically, the leading stop has the advantage. This difference has been interpreted in terms of central versus peripheral masking [M. Studdert‐Kennedy, D. Shankweiler, and S. Schulman, J. Acoust. Soc. Amer. 48, 599–602 (1970)]. Dichotically, the signals travel separate peripheral pathways, and central masking effects are revealed. Monotically, the lagging signal is masked peripherally by the overlapping leading signal. This experiment was designed to determine the effect that the elimination of the temporal overlap would have on the dichotic and monotic masking functions. Syllables 75 msec long were presented at six asynchronies between 0 and 100 msec. The dichotic masking function was unaffected, whereas the monotic lead advantages were substantially reduced at the .
Multispacecraft observations of microscale fluctuations in the solar wind

Three-component magnetic field and solar wind velocity data from the Explorer 33 and 35 spacecraft have been used to study Alfvenic fluctuations in the interplanetary medium. We selected 1/2-hour data periods in which the solar wind velocity fluctuations v and the magnetic field fluctuations b were highly correlated, defined by a correlation coefficient > or =0.6 for two or more components. Simultaneous observations of these fluctuations by both spacecraft at different locations in interplanetary space enabled us to determine the phase front orientations of these phenomena. We analyzed 56 half-hour data periods and were able to obtain relatively accurate phase information for 33 of them. Using the direction of the phase front relative to the average field as the main criterion for identification, we obtained the following results. (1) The minimum variance method does not give a good estimate of the phase from direction of Alfvenic fluctuations. (2) There is a distinct class of Alfvenic fluctuations with phase planes nearly parallel of the mean field B/sub 0/; these could be static structures and/or waves. (3) Most of the fluctuations whose phase planes are not nearly parallel to B/sub 0/; these could be static structures and/or waves. (3) Most of themore » fluctuations whose phase planes are not nearly parallel to B/sub 0/ (i.e., the propagating fluctuations) move neither radially away from the sun nor along B/sub 0/. (4) The characteristic length of the phase fronts of Alfvenic fluctuations is probably significantly larger than 50 R/sub E/. (5) Evidence is presented which indicates that tangential discontinuities and possibly other types of static structures are found among Alfvenic fluctuations, indicating that Alfvenic fluctuations are probably not solely Alfven waves. « less
Stable ℋ∞ flow controller design using approximation of FIR filters

Stable flow controllers are usually preferred since, compared with unstable flow controllers, they are less sensitive to any modelling imperfections. ℋ∞-optimal flow controllers involve finite impulse–response (FIR) filters due to the time delays which are inherent in any practical network. Therefore, design of a stable ℋ∞ flow controller is a difficult problem due to the infinite dimensionality of these FIR filters. In this work, finite-dimensional approximations of FIR filters are used to design stable ℋ∞ flow controllers. Three design approaches are considered and, for each approach, a different algorithm to design a stable ℋ∞ flow controller is developed. Controllers obtained by each agorithm are also compared against each other, as well as against the optimal controller, using an example case.
The Axisymmetric Motion of a Liquid Film on an Unsteady Stretching Surface

The axisymmetric motion of a fluid caused by an unsteady stretching surface that has relevance in extrusion process and bioengineering has been investigated. It has been shown that if the unsteady stretching velocity is prescribed by rb/(1 − αt), then the problem admits a similarity solution which gives much insight to the character of solutions. The asymptotic and numerical solutions are obtained and they could be used in the testing of computer codes or analytical models of more realistic engineering systems. The results are governed by a nondimensional unsteady parameter S and it has been observed that no similarity solutions exist for S > 4
Effect of Cavity Absorption on the Sound Transmission Loss of Steel‐Stud Gypsum Wallboard Partitions

Sound‐transmission‐loss tests were conducted using steel‐stud drywall partitions with a single layer of 12‐in. wallboard on each side to study the effect on acoustical performance due to the physical properties of cavity fill. These tests also compared the results using mineral wool and glass fiber and using studs of different widths. All tests were conducted in accordance with ASTM E90‐66T. The transmission loss and sound‐transmission class (STC) were found to be related directly to the thickness of fibrous absorbing material when used in the full cross area of the stud cavities. The increase in STC due to increasing thickness of the cavity fill is not a linear relationship, since the first inch has the greatest effect. When the absorbing material is placed in less than the full cross area of the stud cavities, the gain in acoustical performance is governed by the volume of the absorption material. The low‐density glass fiber performed as well as high‐density mineral wool except in the middle portion of .
