Some considerations on the challenges related to the use of the new ICNIRP restrictions for human exposure to radiofrequency fields
Authors: Goiceanu Cristian , Danulescu Razvan , Danulescu Eugenia 
Published: May 2023

Abstract
ICNIRP 2020 guidelines for limiting exposure to radiofrequency fields replace the radiofrequency part of the ICNIRP 1998 guidelines for limiting exposure to time-varying electric, magnetic and electromagnetic fields. Besides setting new restrictions that prevent thermal effect they also took over the 100 kHz to 10 MHz part of the ICNIRP 2010 guidelines for limiting exposure to low-frequency electromagnetic fields, which provides restrictions that prevent nerve stimulation effect. The latest guidelines brought many changes to the system of protection against exposure to radiofrequency fields starting with the physical quantities used to express restrictions and continuing with specific restrictions and new exposure metrics employed. For the first time, the case of brief local exposure to intense radiofrequency fields was accounted by ICNIRP for setting new types of exposure restrictions. All these changes led to more detailed and complex guidelines, but their provisions are more difficult to apply in practice. Our paper presents some of the challenges related to the use in practice of the new ICNIRP restrictions for human exposure to radiofrequency fields.

Abstract
The study presents the analysis of the results for indoor radon concentration in the kindergartens of two Bulgarian districts. The study presents the analysis of indoor radon concentration results in kindergartens of two Bulgarian districts. Measurements were performed with a passive method for the period from February to May 2015, in 411 children’s rooms situated in 157 kindergartens. The measured radon concentrations in the children’s rooms were between 10 and 1087 Bq per m. The evaluation of the results showed that in 10% of the kindergarten rooms, the radon concentration is above the national reference level of 300 Bq per m. The influence of the presence of a basement and the implementation of building renovation on the radon concentration were examined. The presence of a basement is a prerequisite for reducing the concentration of radon in the building. It has been proven that renovating the building increases the radon concentration in it. The analysis confirms the necessity of measuring the indoor radon concentration before the renovation and repair of the building, especially the implementation of energy efficiency measures.
Extremity dosimetry for exposed workers in positron emission tomography in Bosnia and Herzegovina

Published: May 2023

Abstract
Occupational exposure in Bosnia and Herzegovina is regulated by the national regulation on radiation protection for occupational and public exposure. All radiation workers are required to be monitored using whole body passive thermoluminescent dosemeters and, in case of non-uniform external exposures, by dosemeters that would indicate dose to the most affected body parts. Exposed workers are almost exclusively employed in the medical field, and some of them work in nuclear medicine departments where they handle unsealed radioactive sources. Introduction of the positron emission tomography–computed tomography (PET–CT) in two largest clinical centers in the country was expected to cause the increase of equivalent doses to hands received by staff handling the positron emitting radionuclides. Hence, routine monitoring of finger doses became a necessity. The purpose of this study was to evaluate the available data on monitoring with ring dosemeters during PET–CT procedure in two hospitals in Bosnia and Herzegovina and compare them with other practices in the nuclear medicine department, as well as with the results of monitoring in other countries. In general, results confirm that effective doses, as well as equivalent doses to hands, are well below annual dose limits. Finger dosemeters have been proven to be an invaluable asset in the incidental situations that sometimes occur in nuclear medicine departments. Different number of patients and differences in injection methodologies are identified as a possible source of differences between doses in two hospitals. Overall, routine evaluation of doses to hands provides a sound basis for possible optimization processes, as well as confirmation of good practices.

Abstract
This study aimed to develop an energy-based Hp(3) measurement method using a solid-state detector (SSD). Incident and entrance surface air kerma were measured using an ionization chamber placed free-in-air and in front of an anthropomorphic or slab phantom. Subsequently, three SSDs were placed free-in-air, and half-value layer and readings were obtained. After measurements, an X-ray beam quality correction factor $\left ({{k}}_{{Q},{{Q}}_{\mathbf{0}}}^{{SSD}}\right)$, backscatter factor (BSF) and conversion factor from incident air kerma to Hp(3) (C3) were determined. Then, the incident air kerma by SSD $\left ({{K}}_{{a},{i}}^{{SSD}}\right )$, Hp(3) and Hp(3)/${{K}}_{{a},{i}}^{{SSD}}$ were calculated. The ${{k}}_{{Q},{{Q}}_{\mathbf{0}}}^{{SSD}}$ was almost consistent for all SSDs. The C3 and BSF were found to increase as tube potential increased. The Hp(3)/${{K}}_{{a},{i}}^{{SSD}}$ calculated with the anthropomorphic and slab phantoms were consistent within 2.1% and 2.6% for all SSDs, respectively. This method improves the energy dependence of Hp(3) measurement and can estimate the Hp(3) measurement error for dedicated Hp(3) dosemeters.
Simulation of cosmic rays inside an aircraft: spectral perturbation and dose reduction due to aircraft structures and contents

Abstract
In this study, an intricate combinatorial geometry model of a Boeing 777-300ER aircraft was constructed for Monte Carlo transport simulations. The aircraft-induced perturbations of the energy spectra and effective doses of secondary cosmic rays at a typical civil aviation altitude (10 km) were investigated on a component-by-component basis, which included neutrons, protons, photons, electrons, positrons, muons and charged pions. Two geomagnetic cutoff rigidities (1.35 and 15.53 GV) and two solar modulation parameters (430 and 1360 MV) were considered in the aforementioned simulations. The characteristics of various cosmic-ray components at six locations along the fuselage were assessed and compared with those of an unperturbed radiation field in the atmosphere. Aircraft structures and contents reduced the effective doses of personnel inside the aircraft to varying degrees, up to an ~32% reduction in the middle section of the passenger cabin. On average, the dose reduction was ~12–16% depending on geomagnetic and solar conditions. Quantifying the aircraft’s self-shielding effects can further improve the estimation accuracy of aircrew and passengers’ exposure to cosmic radiation. Information regarding the perturbed energy spectra of cosmic rays may be useful for designing onboard experiments or analyzing onboard measurement data.
The reception of OHADA law in anglophone Cameroon: appraisal and proposals
Authors: Essoh Clotilde Etoula 
Published: May 2023

Abstract
This article assesses the extent to which the law under the Organisation pour l’Harmonisation en Afrique du Droit des Affaires (OHADA) has been received in anglophone Cameroon after 26 years of existence, with specific focus on the Fako judicial division.1 With regard to the tenets of qualitative research, it is observed that, from the viewpoint of the legal reception technique, it is indisputable that OHADA law has been infused into the English-speaking legal system in Cameroon through legal techniques of transposition. Through the use of interviews and questionnaires as our research tools, it is revealed that this reception remains limited because most judicial actors still find it difficult to implement legislation that they have not yet mastered. Linguistic issues and the difficulties faced in accessing the Common Court of Justice and Arbitration based in Ivory Coast in Abidjan on OHADA-related matters are serious obstacles to its effective implementation. This situation has been worsened by the poor articulation of clichés that tend to radically oppose OHADA law compared to common law principles. This article tries to deconstruct the ideas received as it shows some of the similarities in the substantive law under the two systems and consequently advocates on this basis the idea that efforts be made to familiarize common law jurists with the content of OHADA law. The article recommends that linguistic issues be tackled by OHADA lawmakers right from the stage of legal drafting by using drafting techniques that will reduce the feeling that the common law is being neglected. For uniform acts yet to be translated, the translation process should associate experts in comparative law to enable the use of appropriate legal language in translation from French into English. Only such efforts will entice the common law African countries that are still hesitating to join OHADA law and, by so doing, will render investment in Africa more attractive.
Paternal Western diet causes transgenerational increase in food consumption in Drosophila with parallel alterations in the offspring brain proteome and microRNAs

Published: May 2023

AbstractSeveral lines of evidence indicate that ancestral diet might play an important role in determining offspring's metabolic traits. However, it is not yet clear whether ancestral diet can affect offspring's food choices and feeding behavior. In the current study, taking advantage of Drosophila model system, we demonstrate that paternal Western diet (WD) increases offspring food consumption up to the fourth generation. Paternal WD also induced alterations in F1 offspring brain proteome. Using enrichment analyses of pathways for upregulated and downregulated proteins, we found that upregulated proteins had significant enrichments in terms related to translation and translation factors, whereas downregulated proteins displayed enrichments in small molecule metabolic processes, TCA cycles, and electron transport chain (ETC). Using MIENTURNET miRNA prediction tool, dme‐miR‐10‐3p was identified as the top conserved miRNA predicted to target proteins regulated by ancestral diet. RNAi‐based knockdown of miR‐10 in the brain significantly increased food consumption, implicating miR‐10 as a potential factor in programming feeding behavior. Together, these findings suggest that ancestral nutrition may influence offspring feeding behavior through alterations in miRNAs.

Caring for nonbinary patients
Authors: Curl Kara-anne 
Published: May 2023

ABSTRACT

Nonbinary is an umbrella term that encompasses any person whose gender identity is outside the binary construct of man or woman. An estimated 1.2 million people in the United States identify as nonbinary, a number that most likely will continue to increase as the visibility of people who live outside binary gender increases in our society. Healthcare providers are likely to encounter nonbinary patients but may lack confidence in treating these patients appropriately. This article describes terminology, concepts, and suggestions for clinicians to provide basic respectful and competent care for nonbinary patients.

Mesenteric ischemia in the acute care setting
Authors: Bagley Kimberly , Schuller Jana Grissom 
Published: May 2023

Abstract:
Mesenteric ischemia is a group of disorders requiring prompt identification, supportive care, and treatment. Chronic mesenteric ischemia can develop into acute mesenteric ischemia, which has high mortality. Acute mesenteric ischemia can be occlusive (caused by arterial embolism, arterial thrombosis, or mesenteric venous thrombosis) or nonocclusive, with treatment depending on the underlying cause.
Obesity-related hypertension

Published: May 2023

Abstract:
Obesity increases the risk of hypertension and other cardiometabolic comorbidities. Lifestyle modifications are usually recommended, though lasting effects on weight and BP reduction are limited. Weight-loss medications, especially incretin mimetics, are effective for short- and long-term treatment. Metabolic surgery provides cure of obesity-related hypertension in some patients. NPs are well positioned to manage obesity-related hypertension to improve clinical outcomes of affected individuals.
Association of preoperative nutritional status evaluated by the controlling nutritional status score with walking independence at 180 days postoperatively: a prospective cohort study in Chinese older patients with hip fracture
Authors: Cheng Xinqun , Chen Wei , Yan Jincheng , Yang Zhenbang , Li Chengsi , Wu Dongwei , Wang Tianyu , Zhang Yingze , Zhu Yanbin 
Published: May 2023

Background:
Malnutrition is significantly associated with unfavorable outcomes, but there is little high-level evidence to elucidate the association of malnutrition with losing walking independence (LWI) after hip fracture surgery. This study aimed to assess the association between preoperative nutritional status evaluated by the Controlling Nutritional Status (CONUT) score and walking independence at 180 days postoperatively in Chinese older hip fracture patients.

Methods:
This prospective cohort study included 1958 eligible cases from the SSIOS database. The restricted cubic spline was used to assess the dose-effect relationship between the CONUT score and the recovery of walking independence. Propensity score matching was performed to balance potential preoperative confounders, and multivariate logistic regression analysis was applied to assess the association between malnutrition and LWI with perioperative factors for further adjustment. Furthermore, inverse probability treatment weighting and sensitivity analyses were performed to test the robustness of the results and the Fine and Gray hazard model was applied to adjust the competing risk of death. Subgroup analyses were used to determine potential population heterogeneity.

Results:
The authors found a negative relationship between the preoperative CONUT score and recovery of walking independence at 180 days postoperatively, and that moderate-to-severe malnutrition evaluated by the CONUT score was independently associated with a 1.42-fold (95% CI, 1.12–1.80; P=0.004) increased risk of LWI. The results were overall robust. And in the Fine and Gray hazard model, the result was still statistically significant despite the apparent decrease in the risk estimate from 1.42 to 1.21. Furthermore, significant heterogeneities were observed in the subgroups of age, BMI, American Society of Anesthesiologists score, Charlson’s comorbidity index, and surgical delay (P for interaction < 0.05).

Conclusion:
Preoperative malnutrition is a significant risk factor for LWI after hip fracture surgery, and nutrition screening on admission would generate potential health benefits.
Evaluation of a New Faculty Teaching Workload Model
Authors: Ludwig-Beymer Patti , Rogers Julia L. , Bowers Heather M. , Vottero Beth , Coates Annette 
Published: May 2023

Background:
Creating an equitable faculty workload model is an ongoing concern. This research evaluated the effectiveness of and satisfaction with a new faculty teaching workload model 1 year after implementation.

Methods:
Data were collected through secondary analysis of faculty assignment spreadsheets, online survey of all full-time nursing faculty members, online survey of college of nursing administrators, and financial analysis.

Results:
Individual faculty teaching loads were not consistent with the workload model. Tenure-track faculty members were assigned higher workloads than the model. Faculty members strongly preferred to have input into their schedule. Both faculty members and administrators identified strengths and opportunities for the model.

Conclusions:
Creating equitable faculty assignments is complex. Administrators and faculty members need to establish a mutual understanding of the process used to calculate equitable workloads and protect time for service and scholarship commensurate with faculty rank.

Published: May 2023

Background:
People with schizophrenia experience unique barriers to routine HIV testing, despite increased risk of HIV compared with the general US population. Little is known about how health care delivery system factors affect testing rates or whether there are testing differences for people with schizophrenia.

Setting:
Nationally representative sample of Medicaid enrollees with and without schizophrenia.

Methods:
Using retrospective longitudinal data, we examined whether state-level factors were associated with differences in HIV testing among Medicaid enrollees with schizophrenia compared with frequency-matched controls during 2002–2012. Multivariable logistic regression estimated testing rate differences between and within cohorts.

Results:
Higher HIV testing rates for enrollees with schizophrenia were associated with higher state-level Medicaid spending per enrollee, efforts to reduce Medicaid fragmentation, and higher federal prevention funding. State-level AIDS epidemiology predicted more frequent HIV testing for enrollees with schizophrenia versus controls. Living in rural settings predicted lower HIV testing, especially for people with schizophrenia.

Conclusion:
Overall, state-level predictors of HIV testing rates varied among Medicaid enrollees, although rates were generally higher for those with schizophrenia than controls. Increased HIV testing for people with schizophrenia was associated with coverage of HIV testing when medically necessary, higher Centers for Disease Control and Prevention prevention funding, and higher AIDS incidence, prevalence, and mortality when compared with controls. This analysis suggests that state policymaking has an important role to play in advancing that effort. Overcoming fragmented care systems, sustaining robust prevention funding, and consolidating funding streams in innovative and flexible ways to support more comprehensive systems of care delivery deserve attention.
A Propensity Score–Matched Comparison of Perioperative Outcomes in Prepectoral Smooth Versus Textured Tissue Expander Breast Reconstruction
Authors: Perez Kevin , Rodnoi Pope , Teotia Sumeet S. , Haddock Nicholas T. 
Published: May 2023

IntroductionTextured tissue expanders (TEs) had previously gained popularity due to minimizing expander migration, rotation, and capsule migration. Recent studies, though, have revealed increased risk of anaplastic large-cell lymphoma associated with certain macrotextured implants, prompting surgeons at our institution to switch to smooth TEs; evaluation is thus required for specific viability and similarity of outcomes of smooth TEs. Our study aims to evaluate perioperative complications in prepectoral placement of smooth versus textured TEs.MethodsOur retrospective study evaluated perioperative outcomes of patients who underwent bilateral prepectoral TE placement, with either smooth or textured TE, at an academic institution between 2017 and 2021 performed by 2 reconstructive surgeons. The perioperative period was defined as the interval between expander placement until conversion to flap/implant or removal of TE due to complications. Our primary outcomes included hematoma, seroma, wounds, infection, unspecified redness, total number of complications, and returns to operating room secondary to complications. Secondary outcomes included time to drain removal, total number of expansions, hospital length of stay, length of time until the next breast reconstruction procedure, next breast reconstruction procedure, and number of expansions.ResultsTwo hundred twenty-two patients were evaluated in our study (141 textured, 81 smooth). After propensity matching (71 textured, 71 smooth), our univariate logistic regression showed no significant difference in perioperative complications between smooth and textured expanders (17.1% vs 21.1%;P= 0.396) or complications that required a return to the operating room (10.0% vs 9.2%;P= 0.809). No significant differences were noted for hematoma, seroma, infections, unspecified redness, or wounds between both groups. A significant difference was noted in days to drain out (18.57 ± 8.17 vs 20.13 ± 0.07,P= 0.001) and type of the next breast reconstruction procedure (P< 0.001). Our multivariate regression showed that breast surgeon, hypertension, smoking status, and mastectomy weight were significant for increased risk for complications.ConclusionOur study demonstrates similar rates and effectiveness of smooth versus textured TE when used for prepectoral placement, making smooth TEs a safe and valuable alternative for breast reconstruction because of their decreased risk of anaplastic large-cell lymphoma compared with textured TEs.
