Authors: López Daniela
Published: September 2021

Rejuvenescimento facial é realizado a fim de prevenir ou tratar o envelhecimento da face, devido a perda da elasticidade, queda dos tecidos, músculos e gordura, podendo causar flacidez, linhas de expressão e rugas. A ruga é o sinal de envelhecimento que atua na redução da espessura da pele, por meio da perda de colágeno; proteína importante no tecido conjuntivo, tornandoo mais rígido pouco e a elastina outro componente do mesmo tecido, que após perder sua elasticidade natural, devido a diminuição do número de fibras elásticas. A intradermoterapia ou mesoterapia consiste na aplicação de ativos/fármacos ou mesclas cosméticas por meio de injeção com uma agulha fina na derme. Sendo assim, o objetivo do estudo é identificar os melhores protocolos utilizando a técnica de intradermoterapia injetável para o tratamento de rugas estáticas.

Sendo assim, nos estudos incluídos no presente estudo, demonstraram uma efetividade dos diferentes ativos, para tratamento de rugas afim do rejuvenescimento facial em ambos os sexos. Se mostrando uma técnica com poucos efeitos colaterais e adversos.
Making Sense of Madness : Mental Disorders and the Practices of Case History Writing in the Early Nineteenth Century
Authors: Kovács Janka
Published: September 2021

The article focuses on interpretations of madness in early nineteenth-century Hungary medical practice from a comparative perspective. By relying on the methodological approach of the anthropology of writing and the analytical considerations offered by Michel Foucault’s 1973–1974 lectures on Psychiatric Power, the article discusses the formalized and standardized practices of case history writing. It draws on sources from the teaching clinics at the universities of Pest and Edinburgh, as well as the largest mental asylums in the Habsburg Monarchy in Vienna (est. 1784) and Prague (est. 1790), and the ideal type of mental asylums at the turn of the eighteenth and nineteenth centuries, the York Retreat (est. 1796). In doing so, an attempt is made to reconstruct both the physicians’ gaze and (to a certain extent) the patients’ view, and by examining the therapeutical regime of each hospital and its correlations with the institutional background, uncover whether madness was perceived as a pathological somatic or psychological state in the medical practice of these institutions. This is in and of itself a fundamental question if we seek to understand changing attitudes towards the mad and their curability in a period of transition from a “world without psychiatry” to a “world of psychiatry,” when specialized care was still not an option for many, especially in the East Central European region.
Doctors into Agents : The Technologies of Medical Knowledge and Social Control in State Socialist Hungary
Authors: Lászlófi Viola
Published: September 2021

In this paper, I analyze different situations in which the doctor-patient relationship, the knowledge/information produced within this framework, and the practices of medical questioning came to the fore in the work of the state security services, one of the typical institutions of social observation and surveillance of the Hungarian socialist state. I examine work and recruitment dossiers opened from 1956 to the 1980s which document either physicians’ uses in state security observation of information which they gained about their patients during their professional (medical) activities in or in which the physician-patient relationship appears as a context of the physician’s recruitment. I discuss how physicians constructed the patient when the gaze of the state security forces was also arguably part of their medical gaze. I contend that medical knowledge and, more generally, information revealed in the professional (medical) context and used in the framework of network surveillance, taken out of their strict medical context, constituted a gray zone of power. On the one hand, this information was a useful tool with which the regime could exert some measure of effective social and political control beyond the borders of healthcare, while on the other hand, it could help physicians develop a certain degree of social resistance.
The Journey of a Massage Therapist’s Experience After Receiving a Formal Complaint
Authors: Kennedy, LMT, BCTMB, DrPH Ann Blair
Published: September 2021

Discussions of professionalism and conflict within practice are an important area of enquiry as massage therapy practice continues to be recognized within the health care realm. The scientific literature has paid little attention to these massage therapy professional and ethical dilemmas. Herein, we explore one such area of conflict between a client and therapist in regard to communication and complaints. An interview was conducted to gain further insight to the situation and is structured based upon the following interview guide: description of the instance, how the therapist handled this situation, reflection on how the therapist’s actions contributed to the situation, brief discussion of how other professions handled these types of situations, and reflection on what could have been done differently.
Fermi-LAT Observations of Sagittarius A*: Imaging Analysis
Authors: Cafardo Fabio , Nemmen Rodrigo ,   (Fermi LAT Collaboration)
Published: September 2021

Sagittarius A* (Sgr A*)—the supermassive black hole (SMBH) in the center of our galaxy—has been observed in most of the electromagnetic spectrum, from radio to X-rays. Diffuse γ-ray emission has been observed around Sgr A* and a γ-ray point source has been detected coinciding with the SMBH’s position, although there is no definitive association between the two. In this work, we have used ∼11 yr of Fermi Large Area Telescope observations of the point source 4FGL J1745.6–2859 and performed a detailed imaging analysis across four energy bands. Our goal is to elucidate the nature of the γ-ray emission at the Galactic Center (GC) and whether it is associated with the SMBH. We find that the centroid of the emission approaches Sgr A*’s location as the energy increases. Assuming that the γ-ray point source is located at the GC, we estimate a luminosity of 2.61 × 1036 erg s−1 in the 100 MeV to 500 GeV energy range. This is consistent with Sgr A*’s bolometric luminosity. Based on the point source properties, we ruled out several potential candidates for its nature and favor a cosmic-ray origin either from protons, electrons, or both, accelerated by—or in the vicinity of—the SMBH. Our results indicate that the point source at the GC is indeed the γ-ray counterpart of Sgr A* in the GeV range.

Authors: Rusdin Rusmayanty , Zulkifli Abdullah Andi , Wahiduddin Wahiduddin , Ansariadi Ansariadi , Suriah Suriah , Hidayanti Healthy
Published: September 2021

BACKGROUND: The low adherence to consumption of Fe tablets in adolescent girls illustrates that the iron supplementation program has not been maximized, so the proportion of anemia in the adolescent group is still high. School-based weekly Fe tablet intervention together with education is effective and ideal in preventing anemia. AIM: This study aims to determine the effect of the PAKEM education model on adherence to Fe tablet consumption. METHODS: This research was quasi-experimental with the randomized pre-test-post-test control group design. The population of this study was 249 young women in Class XI of several high schools, SMAN 12 Makassar and SMAN 1 Makassar, based on the results of the initial survey with low adherence to taking Fe tablets. The research sample was obtained by simple random sampling; 70 respondents were divided into intervention and control groups. Data were analyzed using paired t-test, Wilcoxon test, and Mann–Whitney U-test. RESULTS: There was an increase after the PAKEM educational intervention on knowledge (10.91–17.88), attitudes (56.11–73.60), motivation (38.05–53.49), and actions (0.83–7.34). There was a significant difference between the PAKEM intervention group and the leaflet and audiovisual controls on all study variables with p=0.000 (p<0.05). CONCLUSION: The PAKEM education model was more influential than a leaflet and audiovisual media on the compliance of female adolescent Fe tablet consumption. It is recommended for health workers and educators to apply the PAKEM education model to prevent anemia in adolescent girls.

Published: September 2021

BACKGROUND: The presence of a coronavirus disease 2019 (COVID-19) vaccine is very important to produce an immune response that slows down the pandemic.
AIM: This study aims to find out more about the perspective of the Indonesian people which is predicted to affect vaccine acceptance by the public.
METHODS: Quantitative research was conducted using an online survey via a Google form. The survey was conducted from January to February 2021.
RESULTS: There were 225 respondents. The attitude of the community towards the COVID-19 vaccination program, almost all respondents know the free vaccination program (94.4%) and know the purpose of the program (91.8%). There were 23% of respondents who felt that after being vaccinated they would be free from COVID-19 infection and 2.4% stated that they no longer needed to apply health protocols after being vaccinated. There were 8.2% who did not agree with the reasons they did not know its effectiveness, were worried about the side effects and were unsure about the safety of the COVID-19 vaccine.
CONCLUSION: In general, self-confidence, comfort, calculation of benefits versus disadvantages, and shared responsibility, influence a person’s decision to refuse or accept the vaccine.
Economic effects of climate change on global agricultural production
Authors: Fróna Dániel , Szenderák János , Harangi-Rákos Mónika
Published: September 2021

Climate change seems to be larger, more complex and more unpredictable than any other environmental problem. This review deals with the economic effects of climate change on global agricultural production. The causes and consequences of climate change are very diverse, while populations in low-income countries are increasingly exposed to its negative effects. Supplying the population with food is possible with increased agricultural production, but this often occurs under unsustainable circumstances. Increased agricultural production is also one of the main sources of greenhouse gas emissions. In this research we highlight some of the important connections between climate change, population growth and agricultural production.

« Dire la chose derrière les mots amnésiques » (R. Char). Correspondances entre expérience clinique et expérience poétique
Authors: Giust-Desprairies Florence
Published: September 2021

Cet article est une réflexion sur les correspondances qui existent, dans l’expérience de l’auteure, entre composition poétique et disposition clinique ; correspondances, qualifiée de processus poétique . Par processus poétique , il s’agit de distinguer deux moments concernant le récit et son écoute. Dans le premier, le récit se laisse déstabiliser, dans sa construction, par une émergence inattendue. Dans le second, le sujet se met à accueillir les mots qui lui viennent et à les entendre autrement. Une analogie existe entre travail poétique et travail analytique, tous deux, travail de deuil, de rêve, de création fragmentant, transformant, recomposant l’objet perdu. Poésie et clinique s’élaborent comme une autre parole où l’inédit cherche son sens. Mais la parole qu’autorise le site clinique ne poursuit pas le même but, elle ne trouve son efficience qu’à condition d’accepter de s’égarer. L’écriture poétique, quant à elle, cherche les mots qui saisissent l’étrangeté dans le familier et tente de lui donner une forme arrêtée.
Vicissitudes narcissiques, tribulations spéculaires et compétences maternelles
Authors: Sultan Pierre
Published: September 2021

Comment entendre les vicissitudes narcissiques et les tribulations spéculaires de la belle-mère de Blanche-Neige, de Barbe-Bleue et celles de Narcisse ? Leur quête effrénée, qui trahit des écueils dans leur construction identitaire, tente de suppléer au manque initial de l’image complexe et composite, que l’enfant devrait percevoir dans le regard de sa mère posé sur lui. Cette image, teintée d’affects, empreinte d’épaisseur et de chaleur, qui participe à la construction du narcissisme de l’enfant, lui est transmise par une compétence spécifique de la mère (ou de son substitut) que j’ai appelé «  la capacité réfléchissante maternelle  ».
Effective Mori-Zwanzig equation for the reduced-order modeling of stochastic systems
Authors: Zhu Yuanran , Lei Huan
Published: September 2021

Built upon the hypoelliptic analysis of the effective Mori-Zwanzig (EMZ) equation for observables of stochastic dynamical systems, we show that the obtained semigroup estimates for the EMZ equation can be used to derive prior estimates of the observable statistics for systems in the equilibrium and nonequilibrium state. In addition, we introduce both first-principle and data-driven methods to approximate the EMZ memory kernel and prove the convergence of the data-driven parametrization schemes using the regularity estimate of the memory kernel. The analysis results are validated numerically via the Monte-Carlo simulation of the Langevin dynamics for a Fermi-Pasta-Ulam chain model. With the same example, we also show the effectiveness of the proposed memory kernel approximation methods.
Optimal spatial patterns in feeding, fishing, and pollution
Authors: Uecker Hannes
Published: September 2021

Infinite time horizon spatially distributed optimal control problems may show so–called optimal diffusion induced instabilities, which may lead to patterned optimal steady states, although the problem itself is completely homogeneous. Here we show that this can be considered as a generic phenomenon, in problems with scalar distributed states, by computing optimal spatial patterns and their canonical paths in three examples: optimal feeding, optimal fishing, and optimal pollution. The (numerical) analysis uses the continuation and bifurcation package \begin{document}$\mathtt{pde2path} $\end{document} to first compute bifurcation diagrams of canonical steady states, and then time–dependent optimal controls to control the systems from some initial states to a target steady state as \begin{document}$ t\to\infty $\end{document}. We consider two setups: The case of discrete patches in space, which allows to gain intuition and to compute domains of attraction of canonical steady states, and the spatially continuous (PDE) case.

Immune thrombocytopenic purpura (ITP) is an autoimmune disease characterised by production of autoantibodies against platelet surface antigens. Recent studies have demonstrated a paramount association of ITP and Helicobacter pylori (H-pylori) infection with significant rise in platelet count following H-pylori eradication therapy. The H-pylori infection induced ITP is validated by many proposed mechanisms such as molecular mimicry due to production of autoantibodies against H-pylori surface virulent factors (CagA) and cross reactivity of these antibodies with platelet surface antigens (GP IIb/IIIa, GP Ib/IX, and GP Ia/IIa), phagocytic perturbation due to enhanced phagocytic activity of monocytes, enhanced dendritic cell numbers and response, platelets aggregation due to presence of anti- H-pylori IgG and von Willebrand factor (vWf) and finally host immune response against H-pylori virulent factors CagA and VacA leading to ITP. The effectiveness of H-pylori eradication therapy has also been demonstrated with platelet count being used as a predictive factor for assessment of treatment efficacy. Out of 201 patients 118 were responding to the triple therapy and remaining 83 patients were non-responders, showing the response rate of 58.7%. Out of 118 responders 69 patients were showing complete response (CR) and 49 were showing partial response (PR) to the H-pylori eradication therapy. However, more studies are required to elucidate this association and treatment efficacy.

Authors: Chang Yeonhwa , Kim Chanhee , Kim Nayoung , Kim Joon Jai , Lee Heeyoung
Published: September 2021

Objectives: The number of cases of hepatitis A virus (HAV) infections has sharply increased in Korea, especially among young adults. In this study, an HAV outbreak in a facility for disabled people was investigated, and we found epidemiological differences both between 2 different generations and between generally abled and disabled groups.Methods: We analyzed the incubation period and attack rate of an HAV outbreak and investigated the prevalence of HAV antibodies among the staff and residents of a facility for the disabled. We performed a retrospective cohort study during the HAV outbreak, which lasted from February 8 to 25, 2019, including examinations of HAV antibody tests and post-exposure HAV vaccination for the staff or residents of the facility.Results: There were 9 confirmed cases in 2 staff members and 7 residents. Among 53 people (30 staff and 23 residents), except for the 9 confirmed cases and 1 staff member with a known history of HAV infection, HAV seroprevalence was seen in 16.7% of the staff under 40 years of age and 95.2% of those over 40 years of age, while the corresponding rates in the residents were 0.0% and 58.8%, respectively.Conclusions: This result implies that it is necessary to prioritize HAV vaccination for vulnerable groups and workers of residential care facilities.
Age and growth of pompano, Trachinotus ovatus, from the Strait of Messina (central Mediterranean Sea)

Published: September 2021

This is the first paper to provide detailed information on the age and growth of Trachinotus ovatus. The size of the 244 individuals collected in the Strait of Messina ranged from 2.7 to 30.4 cm in fork length (LF) and 0.31 to 508.6 g in body mass (M). The relationship between these parameters (M - LF) was investigated and showed a good fit. Age estimation based on vertebrae and otoliths yielded similar results, suggesting a maximum age of five years. However, the precision and accuracy tests, such as percentage of agreement (PA), mean coefficient of variation (ACV) and average percent error (APE) indicated that the otolith readings (97.83% PA, 0.54% ACV and 0.38% APE) were more reliable for age estimation than vertebrae readings (82.17% PA, 5.33% ACV and 3.77% APE). The multi-model inference approach allowed us to compare different non-linear growth models. The von Bertalanffy model (L∞=29.139, k=0.496 and t0=−0.347) fitted the length-at-age data best. This species has a relatively rapid growth and an estimated longevity of five to seven years. This information could be used for management and first stock assessment studies on T. ovatus in the Mediterranean Sea.
Linguistics – narratives – narratology
Authors: Adam Jean-Michel
Published: September 2021

Do narratives concern only narratology or can they interest linguistics? If we suppose that linguistics cannot consider any unit beyond the sentence, then narratives are not an object for linguistics. But if linguistics do not stop at the sentence, then narratives may be the object of what R. Barthes called, with É. Benveniste, a “linguistics of discourse” or “translinguistics”. Narratology limits investigation to narrativity and different forms of storytelling, whereas, text linguistics and discourse linguistics are not a specifically narrative theory but a theory that includes narrative as one of its objects. This essay shows that the move from a “classical” to a “postclassical narratology” is less a revolution than an evolution. R. Barthes’s anchoring in É. Benveniste’s linguistics of discourse showed the way to a distinctly French postclassical narratology.
I realized that you would conjecture…
Authors: Privat Jean-Marie
Published: September 2021

The short story by Jorge Luis Borges, “Death and the Compass” (Collected Fictions, 1942), stages the life and death struggle between a detective – “a reasoning machine” – modelled on classic detective stories and a killer who follows the rigid rule of societies bound by a strict honour code (brotherhood, blood vengeance, death). The aim of our ethnocritical study is to show how two contradictory worlds (that of writing and literacy and that of folk knowledge) fatally collide through the cunning intelligence of an honour-bound criminal who is a master in the art of cultural syncretism [metis]. Our approach is different to those based on the formal rules of narratology. By examining several examples of cultural and narrative heterophony, we can show how a traditional literary analysis hinders an anthropological interpretation of the story and its structure, as well as the values and beliefs it reflects.
Facing the facts
Authors: Lacoste Charlotte
Published: September 2021

Taking into account an observable tendency in contemporary French literature to refuse fiction and take a sceptical attitude toward narrative in favour of a factualist form of writing that foils any attempt to tell a story in the traditional sense of the term, this article is based on the hypothesis that what the genre of the personal testimony had introduced into literature has been extended to everyday life: in other words an attempt to objectify the data of personal experience in order to document life as it is actually lived. These works, whose authors reveal, record and save facts for posterity by bearing witness to them — thus assuring that they can never be forgiven or forgotten — contribute to the questioning of a certain idea of what literature is, an idea that still holds sway today.
L’abbaye de Montescalari et ses partenaires particuliers (contado florentin, XIe‑XIIe siècles)

Published: September 2021

Le chartrier de San Cassiano de Montescalari donne une connaissance indirecte des sociétés laïques s’organisant autour de cette abbaye vallombrosaine du contado florentin aux xie et xiie siècles. Dans ce fonds documentaire produit pour et par les religieux, de nombreux actes notariaux n’entretiennent a priori aucun rapport direct avec la vie du cloître et des moines. L’étude de deux petits corpus, l’un informant sur les dynamiques foncières d’un territoire fort proche de l’abbaye, l’autre sur une paroisse s’organisant en périphérie de Florence, met en lumière le cheminement de cette documentation laïque vers le chartrier monastique. Elle révèle la place centrale de groupes sociaux évoluant en marge de la clôture et la vie de l’abbaye aux dynamiques laïques.

A Conceptual Framework for an Integrated Information System to Enhance Urban Mobility
Authors: Duarte Sérgio-Pedro , Pinho de Sousa Jorge , Freire de Sousa Jorge
Published: September 2021

The multiplicity of stakeholders in urban contexts can greatly increase the complexity of transportation systems. Since all stakeholders depend, to varying degrees, on the same data to get the information for their mobility, this work considers that an integrated information system, focused on their different needs, will significantly improve the efficiency of transportation systems. A stakeholder-focused system makes the provided information more relevant, while an integrated system fosters the sharing of the data that generates this information. To build such a system, a conceptual framework focused on stakeholders and their decision processes was developed. This new framework takes advantage of existing ones, such as the Zachman framework, the Enterprise Architecture Design, and the Multilevel Service Design. The proposed multidisciplinary approach, putting together information systems (IS) and service design concepts, has considerable potential in ensuring that the right information reaches each stakeholder at the right time.
Web-Based DSS for Resource Allocation in Higher Education
Authors: Martins Carolina Lino , Zaraté Pascale , Teixeira de Almeida Adiel , Araújo de Almeida Jônatas , Morais Danielle Costa
Published: September 2021

The allocation of scarce resources is a complex higher education decision problem, especially when it comes to budget constraints. Therefore, the authors propose a multicriteria web-based decision support system for resource allocation in higher education organizations. To do so, they define an MCDA/M resource allocation model, based on a project portfolio selection problem to set the percentage of the total budget that every alternative should receive. For the web-based DSS, they develop a database model to store and retrieve data, define the user's interface, and they use a web platform to transform the prototype into a web-based system. Also, they run an empirical analysis with an end-user to test the DSS. They show that the system can provide a clear vision of how the resource allocation system works; the mechanism as a whole becomes more transparent to those involved, enabling them to make efficient and reasonable decisions.

COVID-19 safety guidelines for school eye health screening programs
Authors: Prakash Winston D , Khanna Rohit C
Published: September 2021

COVID-19 pandemic has significantly impacted every sphere of life. Health care workers, including eye care professionals, are at a higher risk of contracting infection directly or indirectly. To mitigate the risk of cross-infection among these front-line workers, it is vital to follow appropriate safety protocols. On the other hand, childhood eye conditions lead to permanent vision loss unless these are identified and treated early. School eye health programs are the best option to reach a large childhood population for early detection and treatment of vision-threatening eye conditions. While several clinical safety guidelines have been developed for ophthalmic practice, no such guidelines are available for carrying out school eye health programs. This article aims to set out COVID-19 safety guidelines for conducting school eye health programs in India.
An objective technique to calculate dermis-fat graft volume
Authors: Mukherjee Bipasha
Published: September 2021

We describe an objective method to measure the volume of a dermis-fat graft (DFG) implant for socket reconstruction. We reviewed the charts of 10 patients undergoing dermis fat grafting as a primary or secondary implant for anophthalmic socket reconstruction between January 2018 and December 2019. The amount of the DFG required to replace the volume of an appropriate spherical implant for the operated eye was predetermined. The volume of the DFG implant was measured by the water displacement method as per the Archimedes principle. Patient demographics, complications, and the outcome were analyzed regarding cosmesis and volume replacement. All patients were satisfied with the final cosmesis. Follow-up ranged from 6 to 18 months (mean 10.7 months). Thus, we concluded that the water displacement method is a simple and easy procedure to objectively determine the amount of the autologous DFG needed to replace the volume in an anophthalmic socket.
Normative values of visual evoked potential in adults
Authors: Ekayanti Merry Septemi , Mahama Corry Novita , Ngantung Denny Jefferson
Published: September 2021

Purpose:

Visual evoked potentials (VEP) are used to determine the function of visual pathway from the optic nerve to visual cortex. Various factors may affect VEP response, viz., technical and environmental. The aim of this study is to obtain the normative value of VEP latency and amplitude parameters in adulthood in Indonesia, as well as the relationship of height, weight, body mass index (BMI), head circumference, and visual acuity with the variety of latency and amplitude values of VEP parameters.

Methods:

It is a cross-sectional study on 120 healthy subjects consisting of 60 males and 60 females between 18 and 65 years old. Height, weight, BMI, head circumference, and visual acuity were measured and continued with VEP examination using a 26′ checkerboard pattern on the left and right eyes alternately. All data were collected and analyzed with the Shapiro–Wilk test using statistical software R version 3.5.2.

Results:

Mean value of P100 latency (interocular latency) of left and right eye were 104.6 ± 3.4 ms and 104.1 ± 3.4 ms, respectively, as well as 9.8 ± 4.7 μV and 10.3 ± 5.4 μV for the amplitude. There was no significant difference between the male and female group, as well as on the age group. Female significantly exhibited a higher P100 amplitude than male. The greater the age, the lower amplitude of P100 significantly.

Conclusion:

Gender and age do not affect the P100 latency value but only affect P100 amplitude. Height, weight, BMI, head circumference, and visual acuity also do not affect the P100 latency and amplitude.
Pterygium surgery by double-sliding flaps procedure: Comparison between primary and recurrent pterygia
Authors: Lee Jong Soo , Choi Yun Su , Jo Yeon Ji , Lee Ji-Eun
Published: September 2021

Purpose:

This study aimed to evaluate the surgical outcomes of pterygial excision for primary and recurrent pterygia by a single method of pterygia excision combined with two conjunctival flaps.

Methods:

This retrospective study divided 193 cases of pterygium into the primary (140 cases) and recurrent (53 cases) pterygium groups. Following double-sliding conjunctival transposition flap operation and surgical excision of the pterygium, the success and recurrence rates of pterygial surgery were assessed based on visual acuity and corneal and total astigmatism during follow-up at least 6 months.

Results:

Both primary and recurrent pterygium groups showed significant improvements in visual acuity and astigmatism (corneal and total) between before and after this procedure. Total astigmatism and success rate of primary pterygium were significantly better than those for recurrent pterygium. Two cases (1.4%) of primary pterygium and four cases (7.5%) of recurrent pterygium developed recurrence, corresponding to a rate of 3.1% (6/193 cases). The success rates significantly make a difference between primary and recurrent groups but did not differ significantly between the first recurrent and over twice recurrent pterygium. However, visual acuity, cornea, and total astigmatism improved significantly after surgery in first recurrent group but not in over twice recurrent group.

Conclusion:

The double-sliding conjunctival flaps surgery appeared to be a useful method, with a better success rate and lower pterygial recurrence in pterygium surgery. Especially, when pterygium is larger or recurrent type, this technique can be easily covered the bare sclera, as compared to any transposition conjunctival flap operation.

This study was conducted to evaluate the effect of high intensity interval training (HIIT) on macular microcirculation, measured by swept source optical coherence tomography angiography (ss OCTA) in young football players.

Methods:

Football players between 18–20 years old were included. After a detailed ophthalmological examination, physiological parameters, including height, body weight, body fat, systemic blood pressure, hematocrit values, oxygen saturation, and heart rate, were recorded. Intraocular pressure and ss OCTA parameters were measured one day before and the day after the high intensity interval training program using DRI OCT Triton (Topcon, Tokyo, Japan) between 11:00 am and 1:00 pm.

Results:

Fifteen participants completed the study. All were males with a mean age of 18.1 ± 0.4 years. Systolic and diastolic blood pressure and oxygen saturation did not change significantly (P > 0.05), while hematocrit levels increased remarkably (P = 0.049) after the HIIT program. Heart rates and intraocular pressure decreased (P = 0.003, P = 0.017, respectively). There was a significant increase in the central vessel density in deep capillary plexus (before: 18.7 ± 3.8%, after: 21.1 ± 4.5%) and central vessel density in choriocapillaris (before: 54.5 ± 2.8%, after 56.9 ± 2.2%) (P = 0.02, P = 0.02, respectively), although no changes were observed in other ss OCTA or in the central macular thickness and subfoveal choroidal thickness.

Conclusion:

A 6 week, high intensity interval training program with three exercise sessions per week seems not to alter mean superficial vascular densities, deep foveal avascular zone, and superficial foveal avascular zones, central macular thickness, or subfoveal choroidal thickness, while the central deep vascular density and central choriocapillaris vascular density increased remarkably among ss OCTA parameters.
A clinical study on the correlation between demodex infestation and ocular surface changes in patients with meibomian gland dysfunction
Authors: Pan Shuling , Chen Yan
Published: September 2021

Purpose:

To observe the effect of demodex infection on the ocular surface changes of patients with meibomian gland dysfunction (MGD) and analyze the correlation between the number of demodex and the changes of the ocular surface.

Methods:

Hundred patients with MGD aged 18–70 years who visited the dry eye center of Shanghai Aier Eye Hospital were recruited. All patients were examined with in vivo confocal microscopy to quantify the demodex and divided them into two groups (demodex negative group and demodex positive group) according to the number of demodex mites. The subjects underwent questionnaires of ocular surface disease index (OSDI) and a series of examinations. Parameters including the OSDI score, fluorescein tear film break-up time (FBUT), meibum quality, meibum gland expressibility, meibomian gland dropout (MG dropout), and ocular redness were recorded and compared between the two groups. The correlation between the number of demodex and the ocular surface changes was further analyzed.

Results:

Among 100 patients, 51 were positive for demodex. The demodex-positive group showed significantly increased scores of OSDI (24.41 ± 3.43 vs 20.98 ± 2.31, P = 0.00), ocular redness score (1.38 ± 0.46 vs 1.00 ± 0.30, P = 0.00), and MG dropout (3.00 ± 1.13 vs 2.18 ± 0.64, P = 0.00) and decreased FBUT (6.40 ± 1.63 vs 6.54 ± 1.83, P = 0.00), compared to the demodex-negative group. A significant correlation was noted between the number of demodex and OSDI, ocular redness, and FBUT.

Conclusion:

Ocular demodex infestation might play a role in the ocular surface discomfort, inflammation, and meibomian gland dropout in MGD patients. It is necessary to pay attention to the examination and treatment of demodex mite in patients with MGD.

Background:

Access to the pelvi-calyceal system and subsequent dilatation of the tract are among the initial important steps in percutaneous nephrolithotomy (PCNL). In this study, we share our experience with single-step renal dilatation when compared to multiple serial renal dilatation in PCNL.

Materials and Methods:

This is a retrospective study wherein 35 patients who underwent PCNL by single-step renal dilatation by appropriate size Amplatz Dilator were compared with 35 patients who underwent multi-step serial renal dilatation using serial metallic Alken dilators. These patients were analyzed on the basis of demographic profile, total intra-operative time, fluoroscopic time, intra-operative and postoperative complications, stone clearance, requirement of blood transfusion, duration of hospital stay, and follow-up.

Results:

There were no significant differences in the demographic profile among the patients in these two groups. The mean total operative duration and fluoroscopic duration were less in single step renal dilatation group, and these have been found to be statistically significant (P < 0.05). There were no statistically significant differences in the rates of other complications – incomplete stone clearance, bleeding and hematoma formation, requirement of blood transfusion, duration of hospital stay, and follow-up.

Conclusion:

Operative duration and rate of radiation exposure are significantly less in PCNL by single-step renal dilatation; however, there is no statistically significant difference in the rates of other complications.

Introduction:

Because the reports in the literature of radiologic investigations for upper tract urothelial cancer (UTUC) are limited by the number of patients, and included patients with different pathologies, we aimed to study the overall accuracy of computed tomography (CT) in the diagnosis of UTUC and their accuracy on predicting tumor location.

Methods:

A retrospective review from 1990 to 2017 included patients who were treated for UTUC. Unenhanced CT scan was obtained first using Multi-Detector Computed Tomography (MDCT, Philips Medical Systems), then nonionic contrast medium, containing 350 mg iodine/ml was injected at 4 mL/s. Analysis was performed using SPSS®.

Results:

Of 275 patients, complete data on CT was available on 270 (98%) patients. CT reported only two false positive and six false negative results and the overall accuracy was 96-97%. In comparison to the final pathological reports, CT/CTU detected 85% of the tumor location of in the renal pelvic and 50% of the calyceal tumors. In ureteric tumors, they detected distal (66/71= 93%) more than proximal ureteric tumors (60%).

Conclusion:

In our cohort, CT/ CTU has a high overall accuracy (97%) in diagnosing UTUC, capability to well visualize tumors of distal ureter and renal pelvis, but could miss calyceal tumors. The matter to rely only on CT without ureteroscopic biopsy in the diagnosis of UTUC especially if radical surgery is planned needs further prospective studies.

Published: September 2021

In the medieval period the Casentino was an important center for iron working and for the production of charcoal necessary for this activity. Between XIII and XIV centuries the Guidi family owned various ironworks in the localities of Cetica and Raggiolo. In this area companies of charcoal burners were active and used local forest resources for the production of charcoal. In this study we mapped the old charcoal kiln sites over an area of 1841 hectares located west of the center of Raggiolo. The charcoal kiln sites were mapped by photointerpretation of LiDAR-derived images. The results are discussed on the basis of the historical events that occurred in the study area between the end of the XIII and the first decades of the XIV century.

Published: September 2021

The former “Direzione generale foreste”, established in 2017 under the scope of theMinistry of Agricultural, food and forestry policies is about to become “Direzione generaleeconomia montana e foreste”. With this transformation, new important duties dedicated to themountain ecosystem are about to unfold. As this moment comes, we take the opportunity tolook back at the activities of the Direzione generale foreste, how these developed and the firstresults achieved. Most importantly, though, we address those results that are lying ahead of usand still need our best efforts. Those goals need to be analysed bearing in mind the focal pointsemerged in the report of the IV Italian National Congress of Silviculture (Turin, November2018). The new National Forestry Strategy along with other initiatives will be a turning point forthis sector. Sustainable forest management and careful planning will ensure higher biodiversityin our forests, contribute to the national natural capital along with the economic developmentof mountain and rural areas, where there is the majority of Italian forests.

Background: Inconsistent results about the effect of air pollution on chronic rhinosinusitis (CRS) have been reported. This study aimed to evaluate the impact of meteorological conditions/air pollution on the prevalence of CRS in adult Koreans. Methodology: The data from the Korean National Health Insurance Service-Health Screening Cohort from 2002 through 2015 were used. A CRS group (defined as ICD-10 codes J32, n=6159) was matched with a control group (n=24,636) in 1:4 ratios by age, sex, income, and region of residence. The meteorological conditions and air pollution data included the daily mean, highest, and lowest temperature (°C), daily temperature range (°C), relative humidity (%), ambient atmospheric pressure (hPa), sunshine duration (hr), and the rainfall (mm), SO2 (ppm), NO2 (ppm), O3 (ppm), CO (ppm), and PM10 (μg/m3) levels before the CRS diagnosis. Crude and adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for CRS were analyzed using logistic regression analyses. Results: When the NO2 level increased by 0.1 ppm, the odds for CRS increased 5.40 times, and when the CO level increased by 1 ppm and PM10 increased by 10 μg/m3, the odds for CRS decreased 0.75 times and 0.93 times, respectively. Other meteorological conditions, such as the mean/highest/lowest temperature, temperature range, rainfall and other air pollution, such as SO2 and O3, were not statistically significant. NO2 for 90 days before the index date increased the risk of CRS in all subgroups, except for the nasal polyp and older age subgroups. Conclusion: CRS is related to high concentrations of NO2.
