Adwords with Unknown Budgets and Beyond
Authors: Udwani Rajan 
Published: April 2024

In the classic Adwords problem introduced by [Mehta A, Saberi A, Vazirani U, Vazirani V (2007) Adwords and generalized online matching. J. ACM 54(5):22-es.], we have a bipartite graph between advertisers and queries. Each advertiser has a maximum budget that is known a priori. Queries are unknown a priori and arrive sequentially. When a query arrives, advertisers make bids, and we (immediately and irrevocably) decide which (if any) Ad to display based on the bids and advertiser budgets. The winning advertiser for each query pays their bid up to their remaining budget. Our goal is to maximize total budget used without any foreknowledge of the arrival sequence (which could be adversarial). We consider the setting where the online algorithm does not know the advertisers’ budgets a priori and the budget of an advertiser is revealed to the algorithm only when it is exceeded. A naïve greedy algorithm is 0.5 competitive for this setting, and finding an algorithm with better performance remained an open problem. We show that no deterministic algorithm has competitive ratio better than 0.5 and give the first (randomized) algorithm with strictly better performance guarantee. We show that the competitive ratio of our algorithm is at least 0.522 but also strictly less than [Formula: see text]. We present novel applications of budget oblivious algorithms in search ads and beyond. In particular, we show that our algorithm achieves the best possible performance guarantee for deterministic online matching in the presence of multichannel traffic [Manshadi V, Rodilitz S, Saban D, Suresh A (2022) Online algorithms for matching platforms with multi-channel traffic.

Microjet wound therapy versus sharp debridement on wound size reduction: a pilot randomised controlled trial
Authors: Probst Sebastian , Saini Camille 
Published: April 2024

Objective: There are several methods of treating hard-to-heal (chronic) wounds, each differing in terms of efficiency, selectivity, speed, cost and pain. The objective is to activate a wound to initiate the healing cascade. For this pilot study we assessed the feasibility of a new microjet wound therapy technology compared to standard sharp debridement in wound outcomes. Method: A randomised, controlled, open-label pilot study was conducted in one outpatient wound clinic in Western Switzerland from March 2022 to May 2023. Results: A total of 13 consecutive patients were randomly assigned to receive either microjet wound therapy (n=5) or standard mechanical debridement with instruments (n=8). As a feasibility study, there was insufficient power to detect significant differences between the groups. However, in the intervention group, our analysis may indicate a modestly faster reduction in wound area. Microjet wound therapy appears to alleviate patient anxiety and offer cost savings due to the potential for reduced time, as well as the number of required treatments. This meant fewer overall consultations. Conclusion: This study highlights a trend that may indicate that microjet therapy holds value in promoting faster healing of hard-to-heal wounds, and it provides a feasibility basis for a sufficiently powered multicentre trial.

Published: April 2024

Objective: Family physicians (FPs) in Canada routinely perform in-office cutaneous surgery. There is strong evidence to support a moist wound healing environment, resulting in faster healing times and improved cosmesis. However, the wound care practices of FPs have not been previously studied. We aimed to examine the postoperative wound care practices of FPs after in-office cutaneous surgery. Method: An online survey was distributed to Canadian FPs to determine post-surgical wound care practices. The survey examined moist versus dry wound healing and the reasons for these recommendations were explored. Additional wound care practices were also studied. Appropriate statistical analyses were undertaken. Results: A total of 573 (91.5%) FPs completed the survey. Just under half (49.2%) of FPs recommended moist wound healing to their patients, while the remaining respondents (50.8%) recommended dry wound healing. The most endorsed reason for both moist and dry wound care recommendations was prior training (63.1% and 65.3%, respectively). Most physicians (57.2%) recommended the use of a cream or ointment postoperatively. While there appeared to be consensus on recommending sun avoidance after cutaneous surgery (77.7%), additional wound care practices varied, including: the use of dressings; cleansing practices; smoking cessation; reduction in physical activity; photoprotection; water exposure; and scar treatment/cosmetic use. Conclusion: Almost half of FPs in Canada responding to the survey did not recommend moist wound healing despite strong evidence to support this practice. We also noted a diverse range of postoperative wound care practices after in-office cutaneous surgery. Therefore, these results highlight a critical need for consistent wound care recommendations following cutaneous surgery for FPs in Canada.
Management of post-Mohs surgical wounds with a hypothermically stored amniotic membrane: a case series
Authors: Kapp Daniel , Pfendler Laura 
Published: April 2024

Objective: The aim of this case series is to present an alternative approach to managing post-Mohs Micrographic Surgery (Mohs) wounds with hypothermically stored amniotic membrane (HSAM). Method: A case series of patients with post-Mohs wounds is presented, with four patients referred for hard-to-heal wounds following a Mohs procedure that was performed 1–3 months previously. All wounds underwent weekly assessment, debridement, and application of HSAM and secondary dressings. Treatment also included management of bioburden, proper skin care and compression therapy for lower extremity wounds. Results: This case series of seven wounds consisted of four females and three males with a mean age of 87.6 years. Mean wound size at first application of HSAM was 1.34±1.20cm2. All wounds closed, with an average time to wound closure of 43.7±27.1 days. Patients received an average of 4.6±2.5 HSAM applications. The four post-Mohs wounds with a history of being hard-to-heal had an average time to wound closure of 35.5±16.3 days, with an average duration of 86.5±32.4 days prior to the first HSAM application. Conclusion: The results of this case series suggest that use of HSAM may provide an alternative approach to managing post-Mohs wounds. In addition, these findings suggest that HSAM may be of greatest benefit when applied early after Mohs surgery.
Pleomorphic rhabdomyosarcoma of the vagina: A case report
Authors: Xu Pan , Ling Shan-Shan , Hu E , Yi Bi-Xia 
Published: April 2024

BACKGROUND
Rhabdomyosarcoma (RMS) of the vagina in postmenopausal women is an extremely rare malignant tumor that was originally described as a unique group of soft tissue sarcomas originating from primitive mesenchymal cells. It was first reported in postmenopausal women in 1970, and fewer than 50 postmenopausal patients have been reported to date.
CASE SUMMARY
A 68-year-old multiparous female was admitted to the hospital on October 11, 2023, with the chief complaint of a mass causing vaginal prolapse with incomplete urination that had persisted for 4 months. The vaginal mass was approximately the size of a pigeon egg; after lying down, the vaginal mass retracted. Complete resection was performed, and vaginal pleomorphic RMS was diagnosed based on pathology and immunohistochemical staining features. The patient is currently undergoing chemotherapy. The present study also reviewed the clinical, histological, and immunohistochemical features and latest treatment recommendations for vaginal RMS. Any abnormal vaginal mass should be promptly investigated through pelvic examination and appropriate imaging. The current initial treatment for vaginal RMS is biopsy and primary chemotherapy.
CONCLUSION
When surgery is planned for vaginal RMS, an organ-preserving approach should be considered.

Published: April 2024

The present text builds on an earlier publication* which had the same aim: namely, to encourage clarity and coherence in the interdisciplinary area we called social-to-biological transitions. This burgeoning area of research involves a complex workforce with differing career levels and disciplinary traditions, reflecting which the present authors comment from different perspectives (one author from each of early career research, epidemiology, biology and public health) and invite debate.

Published: April 2024

Background
The Sud-Ouest region of Burkina Faso (especially the Bougouriba valley) has been historically problematic with respect to onchocerciasis control, with a recrudescence of infections after vector control carried out the WHO Onchocerciasis Control Programme was halted in 1989. After 1996, mass drug administration of ivermectin was instigated to control the recrudescence so that it would no longer constitute a public health problem. However, in 2010 WHO changed its recommended policy from control to elimination, and in 2013 biannual Community-Directed Treatment with Ivermectin (CDTI) was instigated. Epidemiological surveys were carried-out in 2011 and 2018 to determine whether CDTI was producing a decline in infection levels and progress towards elimination.

Methodology/Principal findings
A cross-sectional study was conducted across 20 villages in four health districts in 2011 and 29 villages in 2018. Individuals aged five years and above were examined by skin-snip, and the prevalence and microfilarial load was determined for each village.
In 2011, 75% of villages had some infections and 20% had prevalences >5%, with a mean prevalence across all villages of 2.63% (range 0.0–9.7%), and community microfilarial load ranging from 0 to 0.25 microfilariae per biopsy. In 2018, nine villages (= 31% of total) had some infections, with prevalences ranging from 0.41% to 3.54%, and a mean prevalence across all villages of 0.37%. Community microfilarial load ranged from 0 to 0.1. Amongst those people found to be microfilarial positive, 87% had a history of migration.

Conclusions/significance
The endemicity of onchocerciasis infection in the Sud-Ouest region has declined to low levels and seems to be progressing towards elimination. Our findings indicated that biannual CDTI is having good effect, but it should continue for a number of years to ensure elimination of transmission. However, progress towards elimination has a troublesome history in this region, and it would be advisable to select more sentinel villages to have confidence in any future epidemiological and entomological surveys, especially Stop-MDA surveys. With positive individuals migrating between countries, cross-border collaboration needs more attention to ensure effective treatment for onchocerciasis elimination.
Utilization of technology to provide on-the-job trainings on Emergency Obstetric and Neonatal Care: Perspectives of nurses and midwives working in Rwanda’s remote health facilities

Published: April 2024

Introduction
One of the targets for the third sustainable development goals is to reduce worldwide maternal mortality ratio (MMR) to less than 70 deaths per 100,000 live births by 2030. To address issues affecting women and the newborns during childbirth and postnatal period, concerted efforts from governments and their stakeholders are crucial to maximize the use of technology to enhance frontline health professionals’ skills to provide the emergency obstetric and newborn care (EmONC). However, no study has garnered nurses’ and midwives’ perspectives regarding the application of technology-enhanced learning approach to provide on-the-job Continuous Professional Development (CPD) and factors that may influence the application of this training approach in the Rwandan context.

Methods
The study collected data from nurses and midwives from forty (40) public health facilities in remote areas nationwide. The study applied a qualitative descriptive design to explore and describe nurses’ and midwives’ perspectives on the feasibility and acceptability of technology enhanced learning approaches such as e-learning, phone-based remote training, and other online methods to provide trainings in EmONC. Two focus group discussions with EmONC mentors, two with nurses and midwives were conducted. Twelve key informant interviews were conducted. Participants were selected purposively. In total, 54 individuals were included in this study. A thematic approach was used to analyse data.

Results
Nurses and midwives highlighted the need to provide refresher trainings about the management of pre-eclampsia. Most of the EmONC trainings are still provided face-to-face and the use of technology enhanced learning approaches have not yet been embraced in delivering EmONC CPDs for nurses and midwives in remote areas. Nurses and midwives found the first developed prototype of smartphone app training of the EmONC acceptable as it met the midwives’ expectations in terms of the knowledge and skills’ gap in EmONC.

Conclusion
Although the newly developed application was found acceptable, further research involving practical sessions by nurses and midwives using the developed application is needed to garner views about the ease of use of the application, relevance of the EmONC uploaded content on the app, and needed improvements on the app to address their needs in EmONC.
Transsynaptic degeneration of ventral horn motor neurons exists but plays a minor role in lower motor system dysfunction in acute ischemic rats
Authors: Zhang Lei , Liu Jingwen , Liu Mingsheng 
Published: April 2024

Background
As a leading cause of mortality and long-term disability, acute ischemic stroke can produce far-reaching pathophysiological consequences. Accumulating evidence has demonstrated abnormalities in the lower motor system following stroke, while the existence of Transsynaptic degeneration of contralateral spinal cord ventral horn (VH) neurons is still debated.

Methods
Using a rat model of acute ischemic stroke, we analyzed spinal cord VH neuron counts contralaterally and ipsilaterally after stroke with immunofluorescence staining. Furthermore, we estimated the overall lower motor unit abnormalities after stroke by simultaneously measuring the modified neurological severity score (mNSS), compound muscle action potential (CMAP) amplitude, repetitive nerve stimulation (RNS), spinal cord VH neuron counts, and the corresponding muscle fiber morphology. The activation status of microglia and extracellular signal-regulated kinase 1/2 (ERK 1/2) in the spinal cord VH was also assessed.

Results
At 7 days after stroke, the contralateral CMAP amplitudes declined to a nadir indicating lower motor function damage, and significant muscle disuse atrophy was observed on the same side; meanwhile, the VH neurons remained intact. At 14 days after focal stroke, lower motor function recovered with alleviated muscle disuse atrophy, while transsynaptic degeneration occurred on the contralateral side with elevated activation of ERK 1/2, along with the occurrence of neurogenic muscle atrophy. No apparent decrement of CMAP amplitude was observed with RNS during the whole experimental process.

Conclusions
This study offered an overview of changes in the lower motor system in experimental ischemic rats. We demonstrated that transsynaptic degeneration of contralateral VH neurons occurred when lower motor function significantly recovered, which indicated the minor role of transsynaptic degeneration in lower motor dysfunction during the acute and subacute phases of focal ischemic stroke.

Mapping the research landscape of hydrogen supply chains: A bibliometric analysis of citations and co-citations
Authors: Frankowska Marzena , Błoński Krzysztof 
Published: April 2024

The article aims to identify the most influential authors and publications in the research area of hydrogen supply chains. The analysis of the European Union’s strategic documents and hydrogen strategies announced by individual countries indicate that using hydrogen in the economy is becoming significantly more important. Therefore, scientists exploring the above topics in various research settings and scopes should also expect growing interest. The hydrogen economy, including hydrogen supply chains (HSC) as a tool for its implementation, is still a relatively young and dynamic research area. This applies especially to the so-called green hydrogen supply chains where the hydrogen feedstock is the renewable energy source. This work is intended to facilitate the identification of the most essential items of already published scientific works. The work carried out a bibliometric analysis for the research area “hydrogen supply chains”. As a result of the research, the following were identified: (1) the most frequently cited publications and their authors, (2) the journals and authors that had the most significant impact on research in a given area, (3) the publications to be which are most often referred to by authors writing works in the field of HSC, and (4) changes in the importance of places of publication and authors over time. Due to the complexity of the research issues, it is crucial to determine the most significant scientific achievements to date. This should constitute the basic cognitive base for properly implementing newly undertaken research: the hydrogen supply chain.
Legalization of Cannabis Does Not Reduce Opioid Prescribing in Patients With Inflammatory Bowel Disease: A Difference-in-Difference Analysis

Published: April 2024

INTRODUCTION:
Cannabis may provide inflammatory bowel disease (IBD) patients with an alternative to opioids for pain.

METHODS:
We conducted a difference-in-difference analysis using MarketScan. Changes over time in rates of opioid prescribing were compared in states with legalized cannabis to those without.

RESULTS:
We identified 6,240 patients with IBD in states with legalized cannabis and 79,272 patients with IBD in states without legalized cannabis. The rate of opioid prescribing decreased over time in both groups and were not significantly different (attributed differential = 0.34, confidence interval −13.02 to 13.70, P = 0.96).

DISCUSSION:
Opioid prescribing decreased from 2009 to 2016 among patients with IBD in both states with legalized and state without legalized cannabis, similar to what has been observed nationally across a variety of diseases. Cannabis legalization was not associated with a lower rate of opioid prescribing for patients with IBD.

AbstractObjectivesThis study examined the outcomes of training nursing students in CPR skills using the Resuscitation Quality Improvement (RQI) program.MethodsNursing students (n=2,193) in 12 schools across the United States participated in this study. Students performed compressions and bag-masked ventilation on adult and infant manikins using the RQI simulation station without and then with feedback on their performance.ResultsWith real-time, objective feedback from the RQI simulation station, students’ performance of CPR skills improved, and they retained their skills over time.ConclusionsThe RQI program and methodology of feedback is effective for training nursing students to be competent in CPR skills, essential for safe patient care. Nursing and other healthcare professions programs should consider adopting the RQI program for students to develop competency in CPR.
