Postoperative pain analysis in patients with Breast reconstruction using implants
No full textRekonstruktivni zahvat dojke implantatima povezan je s visokom učestalošću poslijeoperacijske boli koja zahtijeva posebnu pažnju i primjenu odgovarajućih metoda za njeno liječenje. Ovo prospektivno kohortno istraživanje provedeno je pomoću upitnika kojeg su ispunile bolesnice podvrgnute rekonstruktivnom zahvatu dojke implantatima u Kliničkom bolničkom centru Zagreb i Klinici za tumore Kliničkog bolničkog centra Sestre milosrdnice. Za potrebe istraživanja samostalno je kreiran upitnik koji se sastoji od uvodnog dijela i numeričke skale za procjenu boli. U istraživanju je sudjelovalo ukupno 50 ispitanica s medicinskom indikacijom za rekonstruktivni zahvat dojke implantatima.
Ciljevi ovog istraživanja su: utvrditi intenzitet boli 1. postoperacijski dan, 10. postoperacijski dan i intenzitet boli 6 mjeseci nakon rekonstruktivnog zahvata dojke implantatima, utvrditi odnos pojave boli i dobi bolesnice te utvrditi utjecaj veličine implantata na pojavu postoperacijske boli. Rezultati ovog istraživanja su pokazali da se bol nakon rekonstruktivnog zahvata dojke implantatima smanjuje, odnosno da je bol najjača 1. postoperativni dan, smanjuje se 10. postoperativni dan, a najmanja je 6 mjeseci nakon zahvata. Rezultati su također pokazali da dob i veličina implantata nemaju utjecaja na jačinu postoperativne boli. S obzirom da je istraživanje pokazalo da bolesnice osjećaju značajnu bol nakon ovog zahvata, a kod nekih žena bol traje i duže vremena nakon operacije, potrebno je više pažnje posvetiti njenom istraživanju u budućosti, pružiti psihološku potporu bolesnicama te primijeniti analgetsku terapiju kada je to potrebno.Breast reconstruction using implant is associated with high frequency of postoperative pain which require special attention and the application of appropriate treatment methods. This prospective cohort study was conducted by a questionnaire filled by patients undergoing Breast reconstruction with implant at the Clinical Hospital Centre Zagreb and the Clinic for Tumors at the Sestre milosrdnice University Hospital Center. For the purposes of research, a questionnaire was created consisting of an introductory part and a numerical scale for the assessment of pain. A total of 50 patients with a medical indication for Breast reconstruction with implant participated in the study.
The aims of this study are: to determine the pain intensity of the first postoperative day, the 10th postoperative day and the pain intensity 6 months after the Breast reconstruction with implant, to determine the relationship between the pain and the age of the patient and to determine the impact of implant size on postoperative pain. The results of this study show that the pain after Breast reconstruction with implant reduces, which means that the pain is the most severe first postoperative day, it reduces 10th postoperative day and it is lowest 6 months after surgery. The results also showed that age and the size of implant not affect the strength of postoperative pain. Since research has shown that patients experience significant pain after this procedure and in some women the pain lasts for a long period ot time after surgery, more attention needs to be devoted to it's future research, psychological support has to be provided and analgesic therapy when needed
Patient satisfaction with the results of applying dermal fillers
No full textUvod: Broj estetskih tretmana raste iz dana u dan, kako u svijetu, tako i u Hrvatskoj. Primjena dermalnih filera radi pomlađivanja jedan je od najčešćih estetskih minimalno invazivnih pos-tupaka.
Cilj: Cilj istraživanja je utvrditi stupanj kvalitete života pacijentica te zadovoljstvo odlukom i ishodom nakon primjene dermalnih filera.
Metode: Prospektivno opservacijsko istraživanje provedeno je u Poliklinici Edumed, a uklju-čivalo je 50 pacijentica. Ispitivanje se vršilo anketnim upitnikom vlastite izrade istraživača na dan aplikacije filera, prije aplikacije, te 2., 14., i 30. dan. Na dan aplikacije pacijentice ispunja-vaju demografske podatke, a upitnikom se ocjenjuje zadovoljstvo kvalitetom života, psihoso-cijane funkcije, zadovoljstvo odlukom i ishodom te pitanja vezana uz nuspojave i rane kom-plikacije dermalnih filera. Odgovori se ocjenjuju Likertovom skalom od 1 do 5.
Rezultati: Usporedbom zadovoljstva kvalitetom života postoji statistički značajna razlika. Za-dovoljstvo je najizraženije 30. dana. Statistički značajna razlika je i u psihosocijalnim funkci-jama te u zadovoljstvu izgledom prije i poslije aplikacije. Preporuke drugima bile su najmanje 2. dan nakon aplikacije. Dob statistički značajno negativno korelira sa zadovoljstvom s kvali-tetom života i psihosocijalnim funkcijama. Stručna sprema pozitivno korelira s preporukama upućenim drugima i bračnim statusom.
Zaključak: Pacijentice nakon aplikacije dermalnih filera imaju statistički značajno veću kvali-tetu života 14. i 30. dan nego li prije aplikacije. Pacijentice su zadovoljne odlukom i ishodom postupka. Statistički značajna razlika je u zadovoljstvu rezultatima, a najveće zadovoljstvo je 30. dan.Introduction: The number of aesthetic treatments is increasing day by day, both in the world and in Croatia. The application of dermal fillers for rejuvenation is one of the most common aesthetic minimally invasive procedures.
Aim: The aim of the research is to determine the level of quality of life of patients and satisfaction with the decision and outcome after the application of dermal fillers.
Methods: A prospective observational study was conducted at the Edumed Polyclinic with 50 included patients. The examination was performed with a questionnaire of the researcher's own development on the day of filler application, before application, and on the 2nd, 14th, and 30th day. On the day of application, patients fill in demographic data, and the questionnaire assesses satisfaction with quality of life, psychosocial function, satisfaction with decision and outcome, and questions related to side effects and early complications of dermal fillers. The answers are graded on a Likert scale from 1 to 5.
Results: By comparing satisfaction with quality of life, there is a statistically significant difference. Satisfaction is most pronounced on the 30th day. There is a statistically significant difference in psychosocial functions and in satisfaction with the appearance before and after application. Recommendations to the others were at least 2 days after application. Age is statistically significantly negatively correlated with satisfaction with quality of life and psychosocial functions. Education is positively correlated with recommendations made to others and marital status.
Conclusion: Patients have a statistically higher quality of life on day 14 and day 30 after dermal filler application than before application. Patients are satisfied with the decision and the outcome of the procedure. There is a statistically significant difference in satisfaction with the results, and the greatest satisfaction is on the 30th day
Utjecaj specifičnih aktivnosti medicinske sestre enterostomalnog terapeuta na kvalitetu života osoba sa stomom
No full textStoma predstavlja kirurški kreiran otvor unutarnjeg organa na površini tijela. Derivacijske stome služe za pražnjenje tjelesnih sadržaja (stolica, urin, slina). Stoma može značajno narušiti kvalitetu života u tjelesnom, psihološkom i socijalnom vidu života. Zdravstvena skrb za osobu sa stomom usmjerena je prema pojedincu i bliskim osobama u zdravstveno-odgojnom te psihološkom smislu. Takvu vrstu zdravstvene njege pruža medicinska sestra enterostomalni terapeut (ET). Enterostomalni terapeut je medicinska sestra specijalizirana za područje rana, stoma i inkontinencije. Za potrebe diplomskog rada provedeno je istraživanje s ciljem potvrde hipoteze, daosobe sa stomom u čije liječenje se uključuju ET, imaju ukupno bolje ishode liječenja, veći stupanj kvalitete života i samostalnosti. U istraživanju je sudjelovalo ukupno 90 ispitanika. Ispitanici skupine 1imaju stomu do 30 dana, skupina 2 do 1 godine. Skupinu 3 čine članovi Ilco udruge osoba sa stomom i nositelji su stome od jedne i više godina. Metoda istraživanja je anketiranje upitnikom tri skupine osoba sa stomom. Skupina 1 i 2 tretirane su u liječenju od strane medicinske sestre ET, skupina 3 od strane medicinske sestre sa standardnim stupnjem znanja o stomi. Rezultati istraživanja potvrđuju hipotezu o boljim ishodima liječenja kod osoba sa stomom u čiju je zdravstvenu skrb uključena medicinska sestra ET. Kod skupine 1 i 2, u svim ispitanim kategorijama nalazimo visok stupanj samostalnosti, uključenosti obitelji i bliskih osoba u edukacijske procese (96,7%), manji broj rehospitalizacija te ranih ili kasnih komplikacija stoma. Kod skupine 3 i nakon dužeg perioda života sa stomom, nalazimo poteškoće sa prilagodbom u mnogim segmentima življenja. Markiranje pozicije stoma, ključan segment u formiranju stome, proveden je u skupini 1 kod 70% ispitanika, skupini 2 kod 33% ispitanika, a u skupini 3 ni kod jednog ispitanika. Preoperativno informiranje bolesnika o mogućnosti formiranja stome provedeno je u skupini 1 kod 96% ispitanika, u skupini 2 kod 76% ispitanika, a u skupini 3 kod 40% ispitanika. U sve tri skupine nalazimo izražen visoki stupanj suglasnosti o potrebi osnivanja posebne savjetodavne službe za osobe sa stomom (do 97,33%) ispitanika. 93% ispitanika sve tri skupine izražava potrebu za postojanjem medicinske sestre enterostomalnog terapeuta u zdravstvenom sustavu.Stoma is surgically created opening of internal organ to the body surface. Derivations (stomas) enableelimination of body excrements (e.g. feces, urine and saliva). Stoma may significantly decrease quality of life (psychical, psychological and social functioning). Health care of the stoma patient has to be directed towards the individual and his/her relatives in technical, educational and psychological sense. This kind of care is provided by the specially trained nurses - enterostomaltherapists (ET). Enterostomal therapist is specially trained in management of wounds, stomas and incontinence.
For the purpose of this thesis, the following research was conducted: primary goal was to confirm the hypothesis that stoma patients under the care of ET nurse have in total better therapy outcomes and higher level of life quality and autonomy. This clinical research included 90 subjects divided into three groups of 30 subjects. Group 1 included subjects that had stoma up to 30 days, Group 2 up to 1 year, and Group 3 included members of Ilco patient group with stoma longer than a year. Method used was a survey. Care of subjects in Group 1 and 2 was conducted by the ET nurses, while care of subjects in Group 3 was conducted by the regular nurses.
Results of this research confirmed the hypothesis about better therapy outcomes at patients with stoma where the ET nurses were involved in the patient care. In Group 1 and 2, the following was confirmed in all studied categories: high level of autonomy and inclusion of family and relatives in educational processes (96,7%), lower number of re-hospitalizations, as well as less early or late-onset of stoma complications. In Group 3, even after longer period of life with stoma, difficulties with adjustment in many life segments were noticed. Stoma site positioning as a key segment in stoma forming was performed at 70% of subjects in Group 1, 33% of subjects in Group 2 and at none of the subjects of subjects in Group 3. Pre-operative information about the possibility of stoma forming is given to the 96% of subjects in Group 1, 76 in Group 2 and 40% in Group 3. Subjects in all three cohorts expressed their need to have specialized support service for patients with stoma (up to 97,33%). 93% of subjects in all three cohorts expressed their need for ET nurse in the healthcare system
Comparison of postoperative pain treatment methods in laparotomized patients with wound catheter and continuous multimodal analgesia
No full textUčinkovito liječenje bola jedno je od ljudskih prava. Etička je dužnost zdravstvenih djelatnika ublažiti bol i patnju. Cilj istraživanja bio je utvrditi razliku kupiranja akutnog poslijeoperacijskog bola intravenskom multimodalnom analgezijom i intravenskom multimodalnom analgezijom uz ranski kateter. Iz medicinske dokumentacije Klinike za tumore, Kliničkog bolničkog centra Sestre milosrdnice, Zagreb, retrospektivnim istraživanjem obrađeni su dostupni podatci bolesnika kojima je učinjena prednja resekcija rektuma u radoblju od 1. travnja 2018., do 30. studenog 2018. Istraživane su dvije skupine od po 30 bolesnika obaju spolova, prosječne dobi od 67,9 ± 8,8 vs 67,9 ± 10,9 godina. Brojčana ocjenjivačka ljestvica bola, broj fentanilskih bolusa, te broj pojava prve peristaltike, procijenjeni su 0., 6., 24. i 48. poslijeoperacijski sat. Kumulativna vrijednost brojčane ocjenjivačke ljestvice bola u skupini bez ranskog katetera bila je 422, a s kateterom 357 (χ2 = 12; SS = 9; P = 0,213). Ukupnost primijenjenih bolusa u skupini bez ranskog katetera bila je 101, a s kateterom 95 (χ2 = 12; SS = 9; P = 0,213). Broj pojave peristaltike u skupini bez katetera bio je 35, a s kateterom je 43 (χ2 = 1; SS = 1; P = 0,317). Rezultati sugeriraju blagu prednost intravenske multimodalne analgezije s ranskim kateterom, ali ona nije statistički ni klinički značajna. Rezultati rada mogli bi biti korisni za poboljšanje algoritma liječenja bola nakon prednje resekcije rektuma.Effective treatment of pain is one of human rights. It is an ethical duty of health care professionals to alleviate pain and suffering. The aim of the research was to determine the acute postoperative pain relief between the intravenous multimodal analgesia and intravenous multimodal analgesia with wound catheter. From medical records of the University Hospital for Tumors, University Hospital Centre Sestre milosrdnice, Zagreb, a retrospective study looked at available data from patients with anterior rectal resection in period from April 1st, 2018 to November 30th, 2018. Two groups of 30 patients of both sexes were investigated, averaging 67.9 ± 8.8 vs. 67.9 ± 10.9 years. The numerical rating scales of pain, the number of fentanyl boluses, and the number of first peristals appeared, were estimated at time 0, and 6th, 24th, and 48th postoperative hours. The cumulative value of the numerical rating scale for pain in the non-wound catheter group was 422, and with the catheter 357 (χ2 = 12; SS = 9; P = 0.213). The total score of boluses in the non-catheter group was 101, with catheter 95 (χ2 = 12; SS = 9; P = 0.213). The total number of peristals in the catheterless group was 35, and with catheter 43 (χ2 = 1, SS = 1, P = 0.317). The results suggest a slight advantage intravenous multimodal analgesia with the wound catheter, but it is neither statistically nor clinically significant. The results of the work could be useful to improve the pain treatment algorithm after anterior rectal resection
Predskazatelji intenziteta akutne poslijeoperacijske boli u bolesnica operiranih radi karcinoma dojke
No full textBol je najstariji medicinski problem, predmet je brojnih istraživanja, a do danas nije nađen način da se objektivizira i izmjeri. Svaki operacijski zahvat predstavlja izazov i mobilizaciju cijelog organizma, a jedan od mehanizama koji se aktivira je i mehanizam bola, koj bi trebao biti tretiran što učinkovitije već tijekom zahvata te neposredno nakon zahvata kako bi se smanjila mogućnost razvoja kronične boli iz akutne poslijeoperacijske boli. Ovim istraživanjem željeli smo utvrditi može li se i u kojoj mjeri već dostupnim upitnicima (Pain Sensitivity Questionnaire PSQ (UBO) i Coping Strategies Questionnaire CSQ (PSC)) i aparatom algometar procijeniti intenzitet i jačina poslijeoperacijske boli i tome prilagoditi protokol analgezije. Istraživanje je provedeno od veljače do travnja u Klinici za Tumore Kliničkog bolničkog centra Sestre milosrdnice u Zagrebu.
Istraživanje je provedeno na 100 bolesnica dobi od 30 do 89 godina koje su primljene u Kliniku radi operacije od karcinoma dojke. Prije operacije bolesnice su ispunile i PSQ (UBO) i CSQ (PSC) upitnike. Prije operacije mjerena je i bolna osjetljivost aparatom algometar što je uključivalo devet mjerenja dok je prosječna vrijednost tih devet mjerenja uzeta kao referentna vrijednost u kasnijem istraživanju. Na svim je pacijenticama primijenjen isti protokol analgezije. Nakon operaciji mjeren je osobni doživljaj boli pomoću NRS skale i to 2, 6, 12, 18, 24, 48 i 72 sata poslije operacije.
Nije utvrđena statistički značajna korelacija između prijeoperacijskog mjerenja boli algometrom i NRS rezultata iz poslijeoperacijskog razdoblja. Međutim, utvrđena je povezanost, iako ne statistički značajna, između rezultata PSQ (UBO) i NRS mjerenja te je daljnim istraživanjem utvrđena značajna statistička korelacija (p<0,05) između ta dva parametra u skupini pacijentica definiranih kao jako osjetljive (ALG<60). Istraživanje je pokazalo da se korištenjem algometra mogu identificirati jako osjetljivi pacijentice te se može unaprijed planirati i prilagoditi analgezijski protokol. Možemo reći da rezultati ovog istraživanja ukazuju da je analgezijski protokol primjenjivan tijekom istraživanja uspješan u prevenciji poslijeoperacijskog bola i da se bolesnice jako osjetljive na bol mogu selektirati algometarskim mjerenjima i PSQ (UBO) upitnikom.
Protokol analgezije primjenjen tijekom istraživanja bio je uspješan u sprečavanju pojave poslijeoperacijske boli. Ipak kod pacijentica visoke osjetljivosti potrebe za dodatnom analgezijom mogle bi biti detektirane i prije operacije mjerenjima algometrom ili PSQ (UBO) upitnikom.Pain is the oldest medical problem, subject to numerous researches and until now modern medicine doesn't have a reliable tools to objectify and measure it. Each surgical procedure represents the challenge and mobilization of the whole body of the patient, and one of the mechanisms that is activated during and after surgery is the pain mechanism. Thus, pain should be treated as effectively during the procedure and immediately after, to reduce the chances of developing chronic pain from acute postoperative pain. With this study, we wanted to determine whether and to what extent already available questionnaires (PSQ (UBO) and CSQ (PSC)) and the algometre can be used in preoperative stage to estimate the intensity and strength of postoperative pain and to adjust the analgesia protocol. The study was conducted from February to April 2019. at the Clinic for Tumor Clinical Hospital Center Sestre milosrdnice in Zagreb.
A study was conducted on 100 female patients aged 30 to 89 who were admitted to the Clinic for breast cancer surgery. Prior to surgery, each participant completed PSQ (UBO) and CSQ (PSC) questionnaires. Prior to surgery pain sensitivity was measured with the algometer which included nine measurements, while the average value of these nine measurements was taken as a reference value in the later study. The same analgesic protocol was applied to all patients included in the study. After the surgery personal pain experience was measured using NRS scales, 2, 6, 12, 18, 24, 48 and 72 hours after the operation.
No statistically significant correlation was found between the preoperative pain measurement by alghometer and NRS results from the postoperative period. However, a correlation was found, although not statistically significant, between the PSQ (UBO) and NRS results and a further significant statistical correlation (p <0.05) was found between these two parameters in the patient group defined as a very sensitive (ALG <60 ). Research has shown that using the algometers can identify very sensitive patients and it is possible to plan and adapt the analgesic protocol prior the operation. We can conclude that the results of this study indicate that the analgesic protocol applied during the research was successful in the prevention of postoperative pain. Also, patients more sensitive to pain can be identified by algometric measurements and the PSQ (UBO) questionnaire. The analgesia protocol applied during the research was successful in preventing the occurrence of postoperative pain. However, in patients with high sensitivity the need for additional
analgesia could be detected even before the operation by measurements with the algometry or PSQ (UBO) questionnaire
Učestalost perioperacijskog gubitka mišićne mase ortopedsko traumatoloških bolesnika u Klinici za traumatologiju
No full textIshod kirurškog liječenja koreliran je nutritivnim statusom bolesnika, kako u situacijama prekomjerne težine, tako i u situacijama malnutricije uz gubitak mišićne mase. Čak i kod bolesnika koji su dobro uhranjeni, neodgovarajuća nutritivna potpora u prijeoperacijskom vremenu ugrožava kirurške postupke. Stanje uhranjenosti možemo utvrditi povezivanjem informacijama koje smo prikupili različitim metodama, a ono je definirano nizom međusobno povezanih čimbenika. Zbog neaktivnosti, smanjene pokretljivosti usred bolesti gubi se mišična masa. To dovodi do ograničenja u svakodnevnim životnim funkcijama. Ako se problem uoči na vrijeme možemo spriječiti neželjene učinke ili ih barem ublažiti. Metode kojima procjenjujemo stanje uhranjenosti dijele se na biokemijske, antropometrijske, anketne, te klinički pregled. Procjenom stanja uhranjenosti, kao standarda dijagnostike i liječenja u hrvatskim bolnicama te primjenom različitih postupaka enteralne prehrane omogućili bi bolju preoperativnu i postoperativnu skrb o bolesniku. U ovom je radu pozornost posvećena istraživanju rizika pothranjenosti kod ortopedskih kirurških bolesnika, pri čemu je obuhvaćeno 57 bolesnika sa područja grada Zagreba i okolice. Istraživanje je provedeno u Kliničkom bolničkom centru Sestre Milosrdnice u Klinici za traumatologiju. Cilj ovog istraživanja bio je utvrditi učestalost pothranjenosti ortopedsko kirurških pacijenata nakon kiurških zahvata lokomotrnog sustava donjih ekstremiteta. U sklopu istraživanja mjerena je mišična masa pomoću bioelektrične impedance u tri navrata. Također mjeren je kožni nabor nadlaktice, leđa i trbuha, te opseg natkoljenice i potkoljenice. Traženi su i podaci o načinu života i kvaliteti života, te su se koristili podaci iz medicinske dokumentacije. Bolesnici su potpisali svojevoljno informirani pristanak za sudjelovanje u kliničkom ispitivanju, koje je bilo odobreno od strane etičkog povjerenstva nakon dostavljene temeljite analize prijedloga istraživanja i prateće dokumentacije. Analizom podataka dobiveno je da pacijenti muškarci imaju značajno bolju mišićnu snagu i indeks mišićne mase u odnosu na pacijentice, te da mlađi pacijenti imaju značajno bolji nutritivni status i veću mišićnu snagu u odnosu na starije pacijente. Analiza podataka govori nam da pacijenti sa ozljedom koljena imaju značajno bolji nutritivni status, bolju mišićnu snagu i veći indeks mišićne mase u odnosu na pacijente s ozljedama drugih regija donjih ekstremiteta. Procjenu stanja uhranjenosti i primjenu različitih tehnika enteralne prehrane trebali bi uvesti u sve bolnice, te bi one trebale biti važne u liječenju i dijagnostici bolesnika.The outcomes of surgical treatment are correlated with the nutritional status of patients, both in overweight and underweight situations with loss of muscle mass. Even in patients who are well-fed, inadequate nutritional support in preoperative time is endangering surgical procedures. Nutritional status is defined by a series of interrelated factors and is determined by the synthesis of information collected through different methods. Muscle-mass is decreasing due to inactivity or reduced mobility caused by illness witch leads to limitations in everyday life functions. If the problem is noticed in time, we can prevent unwanted effects or alleviate them at least. Methods for evaluating certain nutritional status constituents are divided into surveys, anthropometric and biochemical methods, and clinical examination. Evaluation of nutritional status and application of various enteral nutrition modalities should enter standard diagnostic and treatment procedures in Croatian hospitals. In this paper attention is paid to the study of the risk of malnutrition in orthopedic surgeons, involving 57 patients from Zagreb and the surrounding area. The research was conducted at the Clinical Hospital Center of Sestre Milosrdnice in the Clinic for Traumatology. The aim of this study was to determine the incidence of malnutrition of orthopedic surgical patients after the surgical procedure of the locomotor system of the lower extremities. Within the study, muscle mass was measured using bioelectric impedance on three occasions. Also was measured the skin fold of the upper arm, back and abdomen, and the circumference of the upper and lower leg. Data on lifestyle and quality of life were also sought, and data from medical records were used. The patients signed a voluntary informed consent to participate in the clinical trial, which was approved by the ethics committee after a thorough analysis of the research proposal and accompanying documentation was provided. Data analysis showed that male patients had a significantly better muscular strength and muscle mass index than female patients, and that younger patients had significantly better nutritional status and higher muscular strength compared to older patients. Data analysis suggests that patients with knee injuries have significantly better nutritional status, better muscle strength and higher muscle mass index than patients with injuries to other lower extremity regions.
The aim of this research was to compile guidelines for perioperative nutritional support for various enteral nutrition modalities. Evaluation of nutritional status and application of various enteral nutrition modalities should enter standard diagnostic and treatment procedures in Croatian hospitals
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
