Pain at sexual activity induced by an inguinal hernia or as a cause of its repair is not thoroughly studied. Reported frequencies are between 25% and 30% preoperatively and 10% and 15% postoperatively. The primary aim was to analyze pain at sexual activity at 1 year comparing total extraperitoneal with Lichtenstein repair in a randomized setting.
Men, 30 to 60 years old, with a primary inguinal hernia were randomized to total extraperitoneal without mesh fixation or Lichtenstein repair. A questionnaire on pain prevalence, frequency, intensity, and impairment of sexual functions caused by pain at sexual activity was introduced. Clinical examination, a questionnaire on sexual function, and the 36-Item Short Form Survey were performed preoperatively and at 1 and 3 years postoperatively. A risk factor analysis for pain at sexual activity as performed.
A total of 243 patients (111 total extraperitoneal and 132 Lichtenstein) were included between 2008 and 2014; 97% remained for 1-year and 90% for 3-year analyes quality of life. Repair will markedly reduce pain at sexual activity and restore quality of life in most patients without difference between techniques. Patients should be informed on a potential relation between having an inguinal hernia and sexual impairment.The present paper proposes a new adaptive controller with nonlinear modulators to improve the controller adaptability and rudder efficiency so that a satisfactory course tracking performance of ships can be achieved. First, a new adaptive control law on basis of Internal Model Control (IMC) is designed to address the speed dependency of the controller. Three types of nonlinear modulators are then added to the developed adaptive controller to increase the rudder efficiency. Subsequently, the control system's stability is analysed. Both course keeping and changing performance of the proposed controller are investigated via towing tank tests using a ship model of a Liquefied Natural Gas carrier. Finally, the applicability of controllers in shallow water is discussed. During experiments the developed algorithms show satisfactory course tracking ability in shallow and deep water. The advantages of better adaptability and higher rudder efficiency are verified by comparative results. Moreover, the impact of water depth on the controller cannot be ignored.In recent years, artificial intelligence (AI) has been developed vigorously, and a great number of AI autonomous applications have been proposed. However, how to decrease computations and shorten training time with high accuracy under the limited hardware resource is a vital issue. In this paper, on the basis of MobileNet architecture, the dense squeeze with depthwise separable convolutions model is proposed, viz. MiniNet. MiniNet utilizes depthwise and pointwise convolutions, and is composed of the dense connection technique and the Squeeze-and-Excitation operations. The proposed MiniNet model is implemented and experimented with Keras. In experimental results, MiniNet is compared with three existing models, i.e., DenseNet, MobileNet, and SE-Inception-Resnet-v1. To validate that the proposed MiniNet model is provided with less computation and shorter training time, two types as well as large and small datasets are used. The experimental results showed that the proposed MiniNet model significantly reduces the number of parameters and shortens training time efficiently. MiniNet is superior to other models in terms of the lowest parameters, shortest training time, and highest accuracy when the dataset is small, especially. .In this paper, the prescribed-time leader-follower formation control problem is solved for surface vehicles (SVs) suffering from input saturation and unknowns including uncertain dynamics and external disturbances. Based on the information of neighboring vehicles, a distributed prescribed-time observer for estimating states of the leader is proposed. By virtue of input saturation, the saturation errors and system unknowns are observed by a reduced-order prescribed-time estimator. Moreover, to realize the satisfactory formation error constraints, a time scale transformation function based prescribed-time prescribed performance function is proposed, together with error transformations, the transient performance of formation errors is improved. Lyapunov stability theorem and backstepping method prove that the closed-loop system is prescribed-time stable. Simulations are given to illustrate the effectiveness of proposed theoretical results.This paper presents a generalized dynamic robust observer design for uncertain linear time-invariant (LTI) singular systems. In this approach, the state equation of the singular system can consist of parametric uncertainties in three matrices namely the derivative, the system, and the input. The proposed method is according to a new parameterization in the system equations and converting it to a new descriptor model so that in the new structure, the derivative matrix is known. A generalized dynamic robust observer is suggested to estimate the state variables of the system which has more flexibility in contrast with proportional and proportional-integral observers. Also, in this method, in addition to the state variables, whose derivatives are also estimated. A sufficient condition is given in a linear matrix inequality (LMI) form to show the convergence of the observer. Numerical simulation demonstrates the efficacy of the proposed observer.The deregulation of electrical energy grids (EEGs) and surrogating the installation of bulk power plants with distributed generations such as wind energy sources, despite the score of advantages, bring new challenges for the secure operation of these EEGs for their operators. Selleck Uprosertib On the other hand, the deployment of demand response programs (DRPs) alongside the management of these multi-area EEGs (MEEGs) intensifies the complexity of the situation. In this paper, a method is proposed for the secure operation of MEEGs when DRPs are employed to incorporate the end-users in balancing the demand-supply chain. Moreover, the techno-economic impacts of fluctuating nature of wind energy sources are mitigated by coordinating them with energy storage systems (ESSs). To do so, a decentralized probabilistic DC-SCOPF model is developed for the operation of MEEGs with ESS-coordinated wind energy sources when several DRPs are deployed in their different areas. The decentralization of the model is performed based on the optimality condition decomposition (OCD) algorithm which results in a mixed-integer non-linear programming (MINLP) problem for each area of the MEEG. What is more; a priority list of DRPs in different areas of the MEEG is generated based on four criteria including the overall operational cost of the system, the number of critical contingencies as the security measure, the overall shed load, and the peak-to-valley ratio (PVR) of the daily demand curve. Numerical simulations are carried out on the New England 39-bus testbed and obtained results are discussed in depth.It is known that nursing students in an online learning environment may experience challenges related to their quality of life and well-being. However, it is unknown what additional challenges students face in a resource-limited environment like Appalachia. This descriptive study surveyed 154 undergraduate nursing students from a single institution in the Appalachian region at the beginning of the COVID-19 pandemic. Results reveal that students experienced unique resource-related barriers specific to underserved communities that impacted their online learning experiences. Findings offer unique implications for nurse educators facilitating online learning. Specific ideas for those teaching in resource-limited areas are presented.
High flow nasal cannula (HFNC) has significantly success in treating acute respiratory distress while HFNC failure dramatically increases mortality and morbidity.
To describe factors associated with failure of HFNC use in children.
We performed a retrospective observational study using demographic and laboratory findings. We compared clinical and laboratory variables in both successful and failed HFNC groups. The correlations between factors and HFNC failure were constructed by binary logistic regression analysis.
Between August 2016 and May 2018, 250 children receiving HFNC (median age 16 months; range 1-228 months, male 50.8%) were enrolled. Pneumonia was the most common cause of respiratory distress, and the median length of stay (LOS) in hospital was 11 days. HFNC failure was found 16.4% while HFNC complication was 4.8% including epistaxis, pressure sore, and gastric distension. Based on multivariable logistic regression analysis, factors associated with HFNC failure were children with congenital heart disease comorbidity (p = 0.005), HFNC use with maximum FiO
> 0.6 (p = 0.021), lobar infiltration on chest X-ray (p = 0.012), the reduction of heart rate, and respiratory rate <20% after 1h of HFNC use (p = 0.001 and p = 0.001, respectively).
HFNC is feasible to use for children with respiratory distress; however, patients with congenital heart disease, using HFNC with FiO
> 0.6, lobar infiltration on chest X-ray should be closely monitored. Heart rate and respiratory rate are important parameters in addition to clinical assessment for evaluating HFNC failure in children.

Here, a self-charging power system (SCPS) consisting of a 0.94(Bi0.5 Na0.5 )TiO3 -0.06Ba(Zr0.25 Ti0.75 )O3 /polyvinylidenefluoride (BNT-BZT/PVDF) composite film-based triboelectric nanogenerator (TENG) is designed as a wind energy harvester and an all-solid-state lithium-ion battery (ASSLIB) as the energy storage device. The optimized TENG can provide an output voltage of ≈400 V, a current of ≈45 µA, and a maximum power of ≈10.65 mW, respectively. The ASSLIB assembled by LiNiCoMnO2 as the cathode, NiCo2 S4 as the anode, and Li7 La3 Zr2 O12 as the solid electrolyte can maintain a discharge capacity of 51.3 µAh after 200 cycles with a Coulombic efficiency of 98.5%. Particularly, an ASSLIB can be easily charged up to 3.8 V in 58 min using the wind-driven TENG, which can continuously drive 12 parallel-connected white light-emitting diodes (LEDs) or a pH meter. This work demonstrates the development of low-cost, high-performance and high-safety SCPSs and their large-scale practical application in self-powered microelectronic devices.
The sexual and reproductive health care of people with HIV and those at risk of HIV has largely been delivered face-to-face in Australia. These services adapted to the coronavirus disease 2019 (COVID-19) pandemic with a commitment to continued care despite major impacts on existing models and processes. Limited attention has been paid to understanding the perspectives of the sexual and reproductive health care workforce in the research on COVID-19 adaptations.
Semi-structured interviews were conducted between June and September 2021 with 15 key informants representing a diverse range of service settings and professional roles in the Australian sexual and reproductive health sector. Inductive themes were generated through a process of reflexive thematic analysis, informed by our deductive interest in clinical adaptations.
The major adaptations were triage (rapidly adapting service models to protect the most essential forms of care); teamwork (working together to overcome ongoing threats to service quality and staff wellbeing), and the intwined themes of telehealth and trust (remaining connected to marginalised communities through remote care).
