Mandibular left first premolar with three roots and three canals: A case report
Authors: Lin Cheng-Yi , Yu Yue-Yuan 
Published: January 2025

BACKGROUND
The numbers of mandibular first premolar roots and root canals vary, and the incidence of three roots and three canals is 0.09%.
CASE SUMMARY
In this article, we review the root and root canal conditions for the mandibular first premolar and report the case of a mandibular left first premolar with three roots and three canals in a male patient, with suggestions for clinical diagnosis and treatment. The patient was referred by an orthodontist for the extraction of the tooth. Preoperative cone-beam computed tomography examination revealed that it had three roots. Under local anesthesia, the extraction socket was carefully expanded, and the tooth was successfully removed intact using forceps. The procedure was uneventful, with no root fractures, postoperative bleeding, or sensory abnormality observed.
CONCLUSION
The mandibular first premolar is characterized by multiple roots and canal variations that can increase the difficulty of treatment.

AimsThe aim of this study was to explore differences in operative autonomy by trainee gender during orthopaedic training in Ireland and the UK, and to explore differences in operative autonomy by trainee gender with regard to training year, case complexity, index procedures, and speciality area.MethodsThis retrospective cohort study examined all operations recorded by orthopaedic trainees in Ireland and the UK between July 2012 and July 2022. The primary outcome was operative autonomy, which was defined as the trainee performing the case without the supervising trainer scrubbed.ResultsA total of 3,533,223 operations were included for analysis. Overall, male trainees performed 5% more operations with autonomy than female trainees (30.5% vs 25.5%; 95% CI 4.85 to 5.09). Female trainees assisted for 3% more operations (35% vs 32%; 95% CI 2.91 to 3.17) and performed 2% more operations with a supervising trainer scrubbed (39% vs 37%; 95% CI 1.79 to 2.06). Male trainees performed more operations with autonomy than female trainees in every year of training, in each category of case complexity, for each orthopaedic speciality area, and for every index procedure except nerve decompression. When adjusting for year, training level, case complexity, speciality area, and urgency, male trainees had 145% (95% CI 2.18 to 2.76) increased odds of performing an operation with autonomy and 35% (95% CI 1.25 to 1.45) increased odds of performing an operation under trainer supervision, than assisting, compared to female trainees.ConclusionMale trainees perform more operations with autonomy during orthopaedic training than female trainees. Female orthopaedic trainees assist for a greater proportion of cases than their male counterparts. A comprehensive review of trauma and orthopaedic training is needed to identify any additional differences in training opportunities between female and male trainees, particularly with regard to progression through training.Cite this article: Bone Jt Open 2025;6(1):62–73.

Cilj je ispitati učestalost teškoća pri dojenju i učestalost isključivog dojenja u rodilištu s obzirom na stupanj samoefi kasnosti dojenjamajki. U ovoj kohortnoj studiji su sudjelovale 772 majke koje su rodile u Kliničkoj bolnici “Sveti Duh” u Zagrebu u razdoblju od listopada 2010. do siječnja 2011. godine. Majke su u rodilištu ispunile upitnik koji je sadržavao pitanja o demografskim podatcima iteškoćama pri dojenju tijekom prvih 48 sati nakon porođaja te Skalu za mjerenje samoefi kasnosti dojenja (BSES-SF). Podatci o načinu prehrane novorođenčeta prikupljeni su iz medicinske dokumentacije. U statističkoj obradi podataka primijenjeni su χ2 test,Mann-Whitneyev test i Spearmanov koefi cijent korelacije. Teškoće pri dojenju izvijestilo je 450 (58,3%) majki. Nađena je značajnanegativna korelacija između broja teškoća i broja bodova ostvarenih na BSES-SF skali (rs= -0,33, p<0,001). Majke s niskom samoefi kasnošću dojenja češće su imale teškoće pri njemu (64,4% vs. 36,5%, p<0,001) i češće su djelomično dojile u usporedbi s majkamačija je samoefi kasnost visoka (69,5% vs. 30,5%, p<0,001). Zastupljenost pojedinih teškoća pri dojenju (teškoće s tehnikom dojenja,bolne i oštećene bradavice, zastoj mlijeka, percepcija nedovoljne količine mlijeka) bila je značajno češća u majki s niskom samoefi kasnošću dojenja. Rezultati pokazuju da majke s niskom samoefi kasnošću dojenja imaju povećan rizik za pojavu teškoća primjemu i odustajanje od isključivog dojenja tijekom boravka u rodilištu. Ova studija dodatno potvrđuje da je samoefi kasnost dojenjaznačajan čimbenik ranog ishoda dojenja.

Subluksacija peronealnih tetiva unutar omotača novi je klinički entitet koji danas možemo uspješno liječiti tendoskopijom peronealnih tetiva. Bolesnici se, bez ikakvih podataka o ranijoj ozljedi gležnja, žale na vidljiv i palpabilan preskok peronealnih tetivakoji moguizazvati jedino sami, i to aktivnom, maksimalnom kretnjom dorzifl eksije i everzije stopala i gležnja, dok se nikakvom pasivnomkretnjom gležnja on ne može izazvati. Opisana su dva tipa subluksacije: u tipu A tetiva peroneusa longusa subluksira se ispred tetiveperoneusa brevisa, dok se u tipu B tetiva peroneusa longusa subluksira kroz uzdužni rascjep na tetivi peroneusa brevisa, akarakteristično je da oba tipa subluksacije nastaju bez ozljede gornjeg peronealnog retinakula. Od slikovnih metoda od pomoći udijagnostici je dinamički UZV, dok MR i CT pomažu u eventualnom uočavanju uzroka nastanka subluksacije peronealnih tetiva teplaniranju kirurškog liječenja, jer se neoperacijsko liječenje pokazalo nedostatnim. Prikazujemo slučaj trinaestogodišnjeg dječaka ukojeg smo dijagnosticirali tip A subluksacije peronealnih tetiva i kojeg smo uspješno izliječili tendoskopijom peronealnih tetiva. Prednosti ovog minimalno invazivnog kirurškog zahvata su bolji estetski rezultat, manja poslijeoperacijska bolnost, brža poslijeoperacijska rehabilitacija i zadovoljniji bolesnici. Valja istaknuti još jednu prednost, a to je mogućnost konverzije u otvoreni kirurškizahvat u slučaju potrebe.

Published: January 2025

Aim: This study was designed to explore the peculiarities of eating behavior in adolescents with vasovagal syncope and to identify a possible correlation between clinical data and some appetitive traits that could potentially be associated with the development of syncope. Methods: In total, 69 adolescents with vasovagal syncope and 60 healthy participants underwent clinical examination, vitamin panel (pyridoxine, folate, cobalamin, vitamin D), homocysteine testing, and simultaneously completed the Ukrainian validated version of the Adult Eating Behavior Questionnaire. The feasibility, reliability, and validity of the scales were assessed in this version. The associations of Questionnaire scales with syncope characteristics were analyzed. Results: Our study has shown good psychometric properties of the Ukrainian version of the Adult Eating Behavior Questionnaire for assessing eating behavior in adolescents with vasovagal syncope. Our study revealed lower scores on enjoyment of food and greater scores on satiety responsiveness trait in patients with vasovagal syncope. Lower food responsiveness was associated with a higher number of syncope events, and higher food fussiness predicted a longer duration of syncope history. Reduced food responsiveness and fussy eating in adolescents with vasovagal syncope have also been linked to lower levels of neurotropic vitamins and hyperhomocysteinemia. Conclusions: Our analysis suggests that vitamin deficiency and autonomic dysfunction in adolescents with VVS could be linked to eating disturbances. One potential approach for prevention and treatment is to provide nutrition education for syncope patients. Clinicians should be aware of the impact of eating behavior, which could help in preventing future syncope attacks and disease progression.

Published: January 2025

Kronični kašalj kod djece predstavlja složen dijagnostički izazov zbog širokog spektra mogućih uzroka. Iako su respiratorne infekcije, astma, alergijski rinitis i laringofaringealni refluks među najčešćim uzrocima, važnost rjeđih uzroka, poput cistične fibroze, primarne cilijarne diskinezije ili tuberkuloze, ne smije se zanemariti. Pravilan dijagnostički pristup uključuje sveobuhvatnu anamnezu, temeljiti fizički pregled i relevantne dijagnostičke pretrage kako bi se isključili ozbiljni uzroci. Rano prepoznavanje i liječenje uzroka kroničnog kašlja od ključne su važnosti za poboljšanje kvalitete života djece i njihovih obitelji. Kako bi se smanjila učestalost kroničnog kašlja i poboljšala zdravstvena stanja djece, važno je promicati preventivne mjere poput cijepljenja, smanjenja izloženosti iritansima (poput duhanskog dima), te poticanja zdravih životnih navika. Također, primjena novih istraživanja i saznanja o patofiziologiji kroničnog kašlja može pomoći u razvoju učinkovitijih terapija i strategija upravljanja. Zaključno, kronični kašalj kod djece zahtijeva pažljiv i sveobuhvatan pristup koji obuhvaća dijagnostiku, liječenje i prevenciju. Kroz suradnju medicinskih stručnjaka i edukaciju obitelji, možemo osigurati bolju kontrolu nad simptomima i značajno poboljšanje kvalitete života djece koja se suočavaju s ovim izazovom.
Thermo‐TRP regulation by endogenous factors and its physiological function at core body temperature
Authors: Kashio Makiko 
Published: January 2025

AbstractTransient receptor potential (TRP) channels with temperature sensitivities (thermo‐TRPs) are involved in various physiological processes. Thermo‐TRPs that detect temperature changes in peripheral sensory neurons possess indispensable functions in thermosensation, eliciting defensive behavior against noxious temperatures and driving autonomic/behavioral thermoregulatory responses to maintain body temperature in mammals. Moreover, most thermo‐TRPs are functionally expressed in cells and tissues where the temperature is maintained at a constant core body temperature. To perform physiological functions, the activity of each thermo‐TRP channel must be regulated by endogenous mechanisms at body temperature. Dysregulation of this process can lead to various diseases. This review highlights the endogenous factors regulating thermo‐TRP activity and physiological functions at constant core body temperature.

Abstract
From a complex perspective, Birch and Bombieri (1985) proposed the study of an important class of n-dimensional exponential sums for

n

{n=4}

, which was then generalized by Katz (1987) to general positive integer n.
Our previous paper (2022) enhanced the preceding work from a complex point of view and expanded the subject to a p-adic point of view for any positive integer n. In this paper, we investigate the algebraic degree of the above exponential sum as an algebraic integer.
Agency as doing-together: learning from fieldwork experiences
Authors: Hernández García Jone M. , Pujolar Joan , Fernández González Noelia 
Published: January 2025

Abstract
Drawing on the perspective of critical sociolinguistics, this article presents preliminary reflections on the debate on agency in sociolinguistics and linguistic anthropology. It draws upon three studies inspired by the Participatory Action Research (PAR) methodology, conducted in various contexts in the Spanish state: (i) a university setting of the Autonomous Community of Madrid, characterized by a high linguistic diversity that remains largely invisible; (ii) a cultural organization in Catalonia, whose objective is to overcome social and linguistic forms of segregation by fostering contact between recent migrants and the local population; (iii) sport clubs in the Basque Country, where young people are encouraged to use Euskara (the Basque language) and resist the tendency to resort to the more dominant Spanish language. We discuss diverse approaches to the notion of agency, while also offering an innovative perspective grounded in field experience: agency emerges as a “doing-together”, as a dialogic-collaborative process resulting from the interaction of researchers and participants. The outcomes of our interactions in the field extend beyond the confines of research studies, revealing the inherent political dimension of the project. This realization compels us, as researchers, to engage in ongoing reflection both within and beyond the context of fieldwork.

HighlightsObesity and depression are a growing global public health problem affecting people of all ages and socioeconomic status. They are independently among the major risk factors for cardiovascular disease. In terms of biological mechanisms, genetic risk factors have been proposed as a potential factor associated with the comorbidity of depression and obesity. Significant correlations were found between the A/A rs9939609 genotype of the FTO gene and both depression and overweight/obesity compared to non-depressed and normal weight A/T+T/T genotypes in young individuals. Our findings will provide a useful starting point for understanding the biological mechanism involved in the association between obesity and depression in the population.AbstractAim. To analyze the relationship between the rs9939609 T>A genotypes of the FTO gene, depression and overweight/obesity as risk factors for cardiovascular diseases among young people aged 25–34 residing in Novosibirsk.Methods. The population-based study included Novosibirsk residents aged 25–34, the study was conducted in 2013–2016 within the framework of the research topic FWNR-2024-0002. 975 people (43.7% men, Caucasians) were screened, the response rate was 71%. Demographic and social data and anthropometry were collected. All study participants took the “MONICA-MOPSY” psychosocial questionnaire. Genotyping of the FTO gene polymorphism was carried out at the Research Institute of Therapeutic Microbiology and Microbiology, a branch of the Institute of Cytology and Genetics, Siberian Branch of the Russian Academy of Sciences, Novosibirsk.Results. The distribution of the A/A rs9939609 genotype of the FTO gene was higher in both the overweight (36.8%) and obese (45.6%) groups compared to the normal BMI group (17.5%). The distribution of the T/T genotypes was higher in the normal BMI group (51.6%) compared to the overweight (32%) and obese (16.4%) groups. The average BMI (body mass index) values were higher among carriers of the A/A genotype (30.4 ± 7.4 kg/m2) compared to carriers of the A/T (26.4 ± 5.2 kg/m2) and T/T (25.2 ± 5.2 kg/m2) genotypes (p < 0.001). The average depression scores were higher among carriers of the A/A genotype 4.4 ± 2.6, compared to carriers of the A/T genotype 3.1 ± 2.2 and T/T 2.9 ± 2.0 (p < 0.001). Carriage of the A/A genotype of the FTO gene was a predictor of both depression (OR = 3.267; 95% CI 1.770–6.030; p < 0.001) and overweight/obesity (OR = 2.208; 95% CI 1.228–9.777; p < 0.001) compared to carriers of the A/T+T/T genotypes without depression and with normal body weight.Conclusion. The results established the role of the A/A rs9939609 polymorphism of the FTO gene in the comorbidity of depression and obesity.
