Lateral retinacular release combined with MPFL reconstruction for patellofemoral instability: a systematic review
Introduction!#!The role of the lateral retinaculum in patellofemoral instability is still debated. Lateral retinacular release (LRR), has been extensively performed in combination with different surgical procedures, including reconstruction of medio-patellofemoral ligament (MPFL). Despite controversial indications, the results from these studies seem promising. The present study conducts a systematic review about current biomechanical and clinical evidence concerning the role of LRR in combination with MPFL reconstruction. We performed a comprehensive literature research, comparing the outcomes of MPFL reconstruction with and without LRR.!##!Materials and methods!#!This systematic review was conducted according to the PRISMA guidelines. The literature search was performed in August 2020. All articles describing the outcome of isolated MPFL reconstruction alone or in combination with a LRR in patients with recurrent patellofemoral instability were considered for inclusion. Only articles reporting data on patients with a minimum of 12-month follow-up were included. Only articles reporting quantitative data under the outcomes of interest were included.!##!Results!#!A total of 63 articles were eligible for this systematic review, including 2131 knees. The mean follow-up was 40.87 ± 24.1 months. All scores of interests improved in favour of the combined group: Kujala + 3.8% (P = 0.01), Lysholm + 4.2% (P = 0.004), Tegner + 0.8 points (P = 0.04), IKDC + 9.8% (P = 0.02). The ROM was comparable between the two groups (P = 0.4). Similarity was found in terms of positivity to the apprehension test (P = 0.05), rate of complications (P = 0.1), re-dislocations (P = 0.8), and revision surgeries (P = 0.1).!##!Conclusion!#!There is no evidence that adding a lateral release impacts positively on the outcome of MPFL reconstruction.!##!Level of evidence!#!IV, Systematic review
Alf Nilsen-Børsskog — The Author Chosen by the Language
This article discusses Alf Nilsen-Børsskog’s four-volume series of novels Elämän jatko [Continuation of life, 2004–2015], seen as the first literary works treating the Kven culture from a native perspective. Nilsen-Børsskog’s novels are analysed as constituting a “counterstory”, a term coined in the postcolonial cultural research paradigm to refer to self-representation. The Kvens have been considered a national minority in Norway since 1999, and their language has been an official minority language since 2005. The present author scrutinizes how Nilsen-Børsskog’s work differs from previous literary descriptions of this minority, often marked by the frequent use of stereotypes of the Kven language and culture

Neuronal growth on high-aspect-ratio diamond nanopillar arrays for biosensing applications
Monitoring neuronal activity with simultaneously high spatial and temporal resolution in living cell cultures is crucial to advance understanding of the development and functioning of our brain, and to gain further insights in the origin of brain disorders. While it has been demonstrated that the quantum sensing capabilities of nitrogen-vacancy (NV) centers in diamond allow real time detection of action potentials from large neurons in marine invertebrates, quantum monitoring of mammalian neurons (presenting much smaller dimensions and thus producing much lower signal and requiring higher spatial resolution) has hitherto remained elusive. In this context, diamond nanostructuring can offer the opportunity to boost the diamond platform sensitivity to the required level. However, a comprehensive analysis of the impact of a nanostructured diamond surface on the neuronal viability and growth was lacking. Here, we pattern a single crystal diamond surface with large-scale nanopillar arrays and we successfully demonstrate growth of a network of living and functional primary mouse hippocampal neurons on it. Our study on geometrical parameters reveals preferential growth along the nanopillar grid axes with excellent physical contact between cell membrane and nanopillar apex. Our results suggest that neuron growth can be tailored on diamond nanopillars to realize a nanophotonic quantum sensing platform for wide-field and label-free neuronal activity recording with sub-cellular resolution
Conventional versus fast track rehabilitation after total hip replacement
Total hip replacement (THR) is currently the most successful orthopaedic operation worldwide. This success is, however, dependent on the quality and efficiency of postoperative rehabilitation programs following it. In a randomized controlled trial, sixty patients (32 females, 28 males, mean age 68.4 years) undergoing THR for hip arthritis having either a conventional rehabilitation after a normal hospital stay (30 patients) or a fast track rehabilitation program (30 patients) were compared. The mean length of stay in the conventional group was 7.8 (range: 6-11) days compared to 4.5 (range 3-5) days in the fast track group (p=<0.001). Complications included one dislocation in either group, a case of heart failure and a readmission in the conventional group. As regards functional outcome, patients in the conventional group had a mean Harris Hip Score of 69.3 six weeks and 82 twelve weeks postoperatively in comparison to 79 and 91 in the fast track group respectively. The differences were statistically significant (p= 0.013 and 0.002 respectively). In conclusion, fast track rehabilitation after total hip arthroplasty allows early patient’s mobilization and shorter hospital stay with better functional outcome and without increasing the risk of complications or the readmission rate
Johann Siegmund Valentin Popowitsch (Janez Žiga Valentin Popovič), Vocabula Austriaca et Stiriaca 1-2 (Frankfurt am Main 2004)
The Austrian dictionary composed by the Slovenian scho-lar Janez Žiga Valentin Popovič (1705-1774) in the third quarter of the 18th century was only published in 2004, and edited by Richard Reutner, who wrote an extensive introduction to it. The dictionary comprises many language-geographical data for the German language, excellent explanations and many comparisons with much information provided regarding Popovic's mother tongue. The author broad horizon is admirable, especially with regard to the German language area and the linguistic literature of that time.Avstrijski slovar, ki ga je v tretji četrtini 18. stoletja sestavil slovenski učenjak Janez Žiga Valentin Popovič (1705-1774), je izšel šele leta 2004 v uredništvu Richarda Reutnerja, kije k njemu napisal obsežen uvod. Slovar vsebuje mnogo jezikovnogeografskih podatkov za nemščino, odlične razlage in marsikaj primerjalnega, veliko pa se najde tudi v zvezi s Popovičevo materinščino. Občudovanja vredna je avtorjeva razgledanost predvsem po nemškem jezikoslovnem prostoru in po takratni jezikoslovni literaturi
Valentin N. Volóchinov: um filósofo da ciência da linguagem
This text address the work of Russian scholar Valentin N. Vološinov, author of the book Marxism and the Philosophy of Language. The objective is to demonstrate a set of characteristics that place Vološinov as a participant in the critique of science movement, which had its epicenter in Germany, between the years 1840 and 1900. To this end, in addition to a general reflection, which recovers the meaning of the term “criticism” most present in the academic environment of the time, this text considers two points of the much mentioned – and, apparently, somewhat misunderstood – opposition of the Russian thinker to the linguistics of Ferdinand de Saussure, as this linguistics is presented in the Course in General Linguistics. Finally, by way of provocation, this text outlines a few words about the proximity between the epistemological works of Valentin N. Vološinov and Wilhelm Dilthey.Este texto aborda la obra del estudioso ruso Valentin N. Voloshinov, autor de la obra Marxismo y filosofía del lenguaje.

Para ello, además de una reflexión general, que recupera el significado del término “crítica” más presente en el ambiente académico de la época, se consideran dos puntos de la tan mencionada –y, aparentemente, algo incomprendida– oposición del pensador ruso a la lingüística de Ferdinand de Saussure, tal como se presenta esta última en el curso de lingüística general. Al final, a modo de provocación, se esbozan algunas palabras sobre la proximidad entre las obras epistemológicas de Valentin N.
