Looking for appropriateness in follow-up CT of oncologic patients: Results from a cross-sectional study. Eur J Radiol 2023; 167:111080. [PMID: 37683331 DOI: 10.1016/j.ejrad.2023.111080] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2023] [Revised: 08/31/2023] [Accepted: 09/03/2023] [Indexed: 09/10/2023]
Abstract
PURPOSE The objective of this study was to assess the inappropriateness rate of oncological follow-up CT examinations. METHODS Out of 7.000 oncology patients referred for follow-up CT examinations between March and October 2022, a random sample of 10 % was included. Radiology residents assessed the appropriateness using the Italian Society of Medical Oncology (AIOM) guidelines, supervised by senior radiologists. Association between inappropriateness and clinical variables was investigated and variables influencing inappropriateness were analyzed through a binary logistic regression. RESULTS Three-hundred-eighty-eight examinations (56.1 %) were consistent with AIOM guidelines. An additional 100 (14.5 %) examinations did not follow the recommended schedule but were nevertheless considered appropriate because of suspected recurrence/progression (10.7 %) or adverse event requiring imaging assessment (3.8 %). Two-hundred-four (29.4 %) examinations were rated as inappropriate. Inappropriateness causes were as follows: CT not included in the relevant guideline (n = 47); CT extended to additional anatomical regions (n = 59); CT requested at a shorter time-interval (n = 98). No statistically significant difference was found in age, sex, scan region, and primary cancer between appropriate and inappropriate examinations. The only variable significantly associated with inappropriateness was being referred by a specific hospital unit named "unit 2" in the study (p = 0.009), which was demonstrated to be the only appropriateness independent predictor (OR 1.952). CONCLUSION This study shows that majority of oncological patients referred for follow-up CT follows standard guidelines. However, a non-negligible proportion was rated as inappropriate, mainly due to the shorter time-interval. No clinical variable was associated with inappropriateness, except for referral by a specific hospital unit.

Abstract
OBJECTIVES To review the cause, management and outcome in cats with septic peritonitis within the United Kingdom (2008 to 2018) and to identify if previously identified prognostic factors were associated with survival in this population. MATERIALS AND METHODS Clinical records from 10 referral hospitals in United Kingdom were reviewed. Data collected included signalment, clinicopathological data and management techniques. Serum albumin, glucose, lactate and ionised calcium concentration; presence of intraoperative hypotension and correct empirical antibiosis were analysed via logistic regression for association with survival. RESULTS Ninety-five cats were included. The overall survival rate was 66%. Lethargy (89%) and anorexia (75%) were the most common clinical signs, with abdominal pain and vomiting in 44% and 27% of cases, respectively. Gastro-intestinal leakage was the most common source of contamination. The presence of an abdominal mass on clinical examination was not strongly predictive of the presence of neoplasia on histology and did not confer a worse prognosis. Cats presenting with dehiscence of a previous enterotomy/enterectomy did not have a worse prognosis than those presenting with other aetologies. Intraoperative hypotension (adjusted odds ratio 0.173, 95% confidence intervals 0.034 to 0.866, P=0.033) was associated with non-survival. Cats that survived beyond 1 day postoperatively had an improved likelihood of survival (87.5%). All cats that survived beyond 6 days were successfully discharged. CLINICAL SIGNIFICANCE This study describes the largest group of cats with septic peritonitis with an overall survival rate of 66%. The presence of an abdominal mass on clinical examination or having dehiscence of a previous gastrointestinal surgery did not confer a worse prognosis.

Abstract
OBJECTIVE Head and neck region is involved in a high percentage of malignant lesions, and oral squamous cell carcinoma (OSCC) is undoubtedly the most frequently found, accounting for over 90% of malignant tumors. Hormone receptor overexpression, like Estrogen Receptor (ER), Progesterone Receptor (PR) and Endothelial Growth Factor Receptor (EGFR), and signaling have been related to the pathogenesis of OSCC. For metastasis of OSCC, Cancer Stem Cells (CSCs) undergo epithelial to mesenchymal transition (EMT) under the influence of growth factors, cytokines, and regulation of cadherins from the tumor's microenvironment. In this context, the stem cells may become a potential therapeutic target for OSCC through modulation of cytokines and RAS pathway, which is involved in intracell signal transduction. The objective of this study was to suggest an experimental steroidogenic model for OSCC in translational research. PATIENTS AND METHODS Dental-derived Stem Cells (D-dSCs) have been obtained from apical papilla tissue that surrounds the developing tooth of healthy donors and cultured in vitro. The cells have been exposed to different concentrations of Estradiol (E2 - 10 nM and 40 nM) in order to verify their response. The number of cells and cell viability has been evaluated up to 96 hours of treatment. RESULTS The results showed that cell growth was increased under estradiol treatments compared with cells maintained without estradiol. Moreover, no significant difference in cell death levels was detected among treatments. CONCLUSIONS This work underlines as D-dSCs could represent a useful steroidogenic model for the development of the target and gene therapies in OSCC.

Successful endovascular treatment of a recurrent giant celiac artery aneurysm. Radiol Case Rep 2019; 14:723-728.

Abstract
Visceral artery aneurysms are very rare and aneurysms of the celiac trunk are the rarest ones: they are in most cases asymptomatic and their detection is frequently incidental. In this article we report the case of a man affected by severe abdominal pain with a huge aneurysm of the celiac trunk, first successfully treated with coil embolization, but, after 10 months, another endovascular embolization was required for deployment of the metallic coils previously released, ahead into the fund of the sac with recanalization of the aneurysm. A second endovascular treatment was performed with other coils and Amplatzer-Plug. The high risk of rupture makes treatment of such aneurysms mandatory and surgery is still considered the gold standard therapy of VAA, but, due to its high morbidity and mortality risks, in the last years, it has been widely replaced by endovascular embolization. An effective endovascular embolization requires not only the complete filling of the aneurysmal sac, but also the complete vascular exclusion of its in-flow and out-flow tracts, to reduce the risk of its anterograde or retrograde reperfusion.

Abstract
Bovine tuberculosis (bTB) is a zoonosis caused mainly by Mycobacterium bovis that affects domestic and wild animals. In Brazil, there are no epidemiological studies on tuberculosis in wild animal populations and their possible role in the disease maintenance in cattle herds; thus, the aim of this study was to evaluate the occurrence of tuberculosis in wild boars in Rio Grande do Sul, southern Brazil. Tissue samples of animals hunted under government consent were submitted to histopathology and M. bovis polymerase chain reaction (PCR) as screening tests; the positive samples were subsequently submitted to bacterial isolation, the gold standard diagnosis. Eighty animals were evaluated, of which 27.9% and 31.3% showed histopathological changes and M. bovis genome presence, respectively. Moreover, 23.8% of the animals had at least one organ with isolates classified as Mycobacterium tuberculosis complex (MTC). Three hunting points were risk factors for positive results on screening tests. This study shows the occurrence of tuberculosis in a wild boars' population, and raise the possibility of these animals to play a role as disease reservoirs in southern Brazil. These results may help to improve the Brazilian tuberculosis control programme, as well as elucidate the circulation of mycobacteria in this country.

Abstract
INTRODUCTION Occult hepatitis B infection (OBI), a virological condition characterized by a low release of Hepatitis B Virus (HBV) from liver cells and low HBV-DNA levels in serum and/or liver tissue of HBsAg-negative subjects, may reactivate in oncohematological patients undergoing immunosuppression by aggressive chemotherapy or hematopoietic stem cell transplantation. The entity of OBI reactivation varies from an increase in HBV replication without liver damage to an active HBV replication followed by liver cell necrosis, frequently severe and in some cases life threatening. Because of a possible severe outcome associated with OBI reactivation (hepatic failure or death due to the discontinuation of chemotherapy), prophylaxis with anti-HBV nucleot(s)ide analogues is recommended in relation to the foreseeable degree of immunosuppression. MATERIALS AND METHODS This review article focuses on the clinical impact of OBI in the oncohematological setting and is addressed to all health care workers having in care oncohematological patients or involved in the treatment of HBV infection and OBI prophylaxis. CONCLUSION International guidelines have indicated lamivudine prophylaxis in hematopoietic stem cell transplantation and when high-dose corticosteroids or anti-CD20 or anti-CD52 monoclonal antibodies are used. Entecavir or tenofovir should replace lamivudine for patients with advanced liver diseases for whom reactivation of OBI may be life threatening. When anti-CD20 or anti-CD52 sparing schedules or other non-aggressive chemotherapies are used, monitoring may be indicated, but very early treatment with highly effective antiviral drugs (entecavir or tenofovir) should be administered once a reactivation of OBI has occurred.

Abstract
Languages have diverse strategies for marking agentivity and number. These strategies are negotiated to create combinatorial systems. We consider the emergence of these strategies by studying features of movement in a young sign language in Nicaragua (NSL). We compare two age cohorts of Nicaraguan signers (NSL1 and NSL2), adult homesigners in Nicaragua (deaf individuals creating a gestural system without linguistic input), signers of American and Italian Sign Languages (ASL and LIS), and hearing individuals asked to gesture silently. We find that all groups use movement axis and repetition to encode agentivity and number, suggesting that these properties are grounded in action experiences common to all participants. We find another feature - unpunctuated repetition - in the sign systems (ASL, LIS, NSL, Homesign) but not in silent gesture. Homesigners and NSL1 signers use the unpunctuated form, but limit its use to No-Agent contexts; NSL2 signers use the form across No-Agent and Agent contexts. A single individual can thus construct a marker for number without benefit of a linguistic community (homesign), but generalizing this form across agentive conditions requires an additional step. This step does not appear to be achieved when a linguistic community is first formed (NSL1), but requires transmission across generations of learners (NSL2).

Watching language grow in the manual modality: nominals, predicates, and handshapes. Cognition 2015; 136:381-95.

Abstract
All languages, both spoken and signed, make a formal distinction between two types of terms in a proposition--terms that identify what is to be talked about (nominals) and terms that say something about this topic (predicates). Here we explore conditions that could lead to this property by charting its development in a newly emerging language--Nicaraguan Sign Language (NSL). We examine how handshape is used in nominals vs. predicates in three Nicaraguan groups: (1) homesigners who are not part of the Deaf community and use their own gestures, called homesigns, to communicate; (2) NSL cohort 1 signers who fashioned the first stage of NSL; (3) NSL cohort 2 signers who learned NSL from cohort 1. We compare these three groups to a fourth: (4) native signers of American Sign Language (ASL), an established sign language. We focus on handshape in predicates that are part of a productive classifier system in ASL; handshape in these predicates varies systematically across agent vs. no-agent contexts, unlike handshape in the nominals we study, which does not vary across these contexts. We found that all four groups, including homesigners, used handshape differently in nominals vs. predicates--they displayed variability in handshape form across agent vs. no-agent contexts in predicates, but not in nominals. Variability thus differed in predicates and nominals: (1) In predicates, the variability across grammatical contexts (agent vs. no-agent) was systematic in all four groups, suggesting that handshape functioned as a productive morphological marker on predicate signs, even in homesign. This grammatical use of handshape can thus appear in the earliest stages of an emerging language. (2) In nominals, there was no variability across grammatical contexts (agent vs. no-agent), but there was variability within- and across-individuals in the handshape used in the nominal for a particular object. This variability was striking in homesigners (an individual homesigner did not necessarily use the same handshape in every nominal he produced for a particular object), but decreased in the first cohort of NSL and remained relatively constant in the second cohort. Stability in the lexical use of handshape in nominals thus does not seem to emerge unless there is pressure from a peer linguistic community. Taken together, our findings argue that a community of users is essential to arrive at a stable nominal lexicon, but not to establish a productive morphological marker in predicates. Examining the steps a manual communication system takes as it moves toward becoming a fully-fledged language offers a unique window onto factors that have made human language what it is.

Abstract
Although monitoring tuberculosis (TB) infection during long-term treatment with tumour necrosis factor (TNF) antagonists is of great importance, no monitoring strategy has yet proved successful. Indeed, even the newly proposed interferon-gamma release assays (IGRAs) are known to produce dynamic changes in IFN-γ plasma levels, making them unreliable indicators of patients' pathological/clinical status. We used intracellular cytokine flow cytometry (ICCFC) to investigate the performance of multi-functional CD4(+) T cells producing IFN-γ, interleukin (IL)-2 and/or TNF in response to Mycobacterium tuberculosis-specific antigens in subjects treated with TNF antagonists. Patients were classified into three groups based on their TB status before commencement of treatment and on IFN-γ level fluctuations evaluated by IGRA during a 36-month follow-up period. The cytokine profile of M. tuberculosis-specific CD4(+) T cells showed that latent tuberculosis infection (LTBI) subjects had a higher frequency of double-positive IFN-γ(+) IL-2(+) CD4(+) T cells and triple-positive IFN-γ(+) IL-2(+) TNF(+) CD4(+) T cells compared to those without LTBI, who showed IFN-γ-level fluctuations over time. In contrast, this latter group of patients showed similar proportions of cells producing IFN-γ alone, IL-2 alone and IL-2 in combination with TNF in response to M. tuberculosis-specific antigens. It therefore appears that patients with and without LTBI infection are characterized by different intracellular cytokine profiles. This is the first study evaluating ICCFC in patients treated with TNF antagonists, and suggests that multi-functional analysis of CD4(+) T cells could be useful for ruling out TB infection in patients classified at screening as LTBI-negative but who show IGRA fluctuations under long-term TNF antagonist treatment.

Abstract
From 2005 to 2012, 236 new substances have been officially notified in European Union via the Early Warning System with an increasing trend from year by year. In October 2009, 4-methylamphetamine (4-MA), an amphetamine derivative, was detected in Belgium and on 14 December 2009 this stimulant was notified to the European Monitoring Centre for Drugs and Drug Addiction. Since its appearance within the recreational drug market, some cases of severe intoxication and deaths have been signaled across Europe. In this paper we summarized the chemical, pharmacological and toxicological information about this new potential recreational drug.

Abstract
Methoxetamine is a dissociative anaesthetic showing pharmacodynamic similarities with its analogue ketamine, a medication with demonstrated rapid-acting antidepressant effects. Like ketamine and other arylcyclohexylamine compounds, methoxetamine is thought to be both a noncompetitive NMDA receptor antagonist and a dopamine reuptake inhibitor. Furthermore, it acts as an agonist at dopamine D2, serotonin 5HT2, muscarinic cholinergic, sigma-1, opioid mu and k receptors. The hypothesis is that methoxetamine can produce rapid antidepressant effects in patients with resistant and non-resistant unipolar and bipolar depression.

In 2000s, many synthetic cathinones have received a renewed popularity as designer drugs of abuse, particularly among young people. Despite being marketed as "bath salts" or "plant food" and labeled "not for human consumption", people utilize these substances for their amphetamine or cocaine like effects. Since the time of their appearance in the recreational drug market, in several countries have been signaled numerous confirmed cases of abuse, dependence, severe intoxication and deaths related to the consumption of synthetic cathinones. The aim of this paper is to summarize the clinical, pharmacological and toxicological information about this new class of designer drugs of abuse.

Abstract
Dislocation and migration of the inferior vena cava filter to the right heart is an uncommon but serious complication, requiring prompt diagnosis and appropriate therapy. We report the case of a seventy-year old man, who had previously undergone vena cava filter implantation and who was admitted to the Intensive Care Unit due to acute respiratory distress with the suspect of pneumonia-related sepsis. Due to the worsening of hemodynamics and the development of cardiogenic shock, the patient underwent bedside echocardiography, which on the contrary revealed dislocation of the filter and the entrapment of the device within the tricuspid valve and chordae tendineae. This evidence was confirmed also by the chest-abdominal X-ray. The patient underwent tricuspid valve surgical replacement and successfully recovered. The transthoracic and transesophageal echocardiographies performed in the intensive care unit were able to first orient the diagnostic efforts toward the correct cause.

Abstract
The illicit marketplace of substances of abuse continually offers for sale legal alternatives to controlled drugs to a large public. In recent years, a new group of designer drugs, the synthetic cathinones, has emerged as a new trend, particularly among young people. The 3,4-methylenedioxypyrovalerone (MDPV), one of this synthetic compounds, caused an international alert for its cardiovascular and neurological toxicity. This substance, sold as bath salts, has caused many serious intoxications and some deaths in several countries. The aim of this paper is summarise the clinical, pharmacological and toxicological information about this new designer drug.

Suboptimal response to GnRHa long protocol is associated with a common LH polymorphism. Reprod Biomed Online 2011; 22 Suppl 1:S67-72.

Abstract
The aim of this observational preliminary trial was to estimate the association between the most common polymorphism of LH (LH-β variant: v-βLH), with different profiles of ovarian response to recombinant human FSH (rhFSH). A total of 60 normogonadotrophic patients undergoing a gonadotrophin-releasing hormone analogue long down-regulation protocol followed by stimulation with recombinant human FSH (rhFSH) for IVF/intracytoplasmic sperm injection, and in whom at least five oocytes were retrieved were retrospectively included. On the basis of the total rhFSH consumption, patients were divided into three groups: Group A: 22 women requiring a cumulative dose of rhFSH >3500 IU; Group B: 15 patients requiring 2000-3500 IU; Group C (control): 23 women requiring <2000 IU. The presence of v-βLH was evaluated using specific immunoassays. Peak oestradiol concentrations were significantly lower in Group A when compared with both groups B (P < 0.05) and C (P < 0.001). Group A had a significantly lower (P < 0.05) number of oocytes retrieved (7.3 ± 1.5, 11.7 ± 2.4 and 14.7 ± 4.1 in the three groups, respectively). Seven carriers (31.8%) of v-βLH were found in Group A, whereas only one variant (6.7%) was observed in Group B; no variant was detected in Group C. These preliminary results suggest that v-βLH is more frequent in women with ovarian resistance to rhFSH.

Abstract
Purpose This paper describes the radiological and clinical findings identified in a group of patients with H1N1 influenza. Materials and methods Between May and mid-November 2009, 3,649 patients with suspected H1N1 influenza presented to our hospital. Our study population comprised 167 (91 male, 76 female patients, age range 11 months to 82 years; mean age 29 years) out of 1,896 patients with throat swab positive for H1N1 and clinical and laboratory findings indicative of viral influenza. All 167 patients were studied by chest X-ray (CXR), and 20 patients with positive CXR and worsening clinical condition also underwent computed tomography (CT). The following findings were evaluated on both modalities: interstitial reticulation (IR), nodules (N), ground-glass opacities (GGO), consolidations (CONS), bacterial superinfection and pulmonary complications. Results Ninety of 167 patients had positive CXR results. Abnormalities identified on CXR, variously combined and distributed, were as follows: 53 IR, 5 N, 13 GGO, 50 CONS; the predominant combination was represented by six GGO with CONS. Of the 20 CXR-positive cases also studied by CT, 17 showed pathological findings. The abnormalities identified on CT, variously combined and distributed, were as follows: 14 IR, 2 N, 5 GGO; the predominant combination was 10 GGO with CONS. Despite the differences between the two modalities, the principle radiological findings of bacterial superinfection were tree-in-bud pattern, consolidation with air bronchogram, and pleural and pericardial effusion. Fifteen of the 20 patients studied by both CXR and chest CT showed respiratory complications with bilateral and diffuse CONS on CXR and CT. Six of 15 died: 4/6 of acute respiratory distress syndrome and 2/6 of multiple organ failure. Conclusions Our study describes the radiological and clinical characteristics of a large population of patients affected by H1N1 influenza. CXR and chest CT identified the site and extent of the pulmonary lesions and documented signs of bacterial superinfection and pulmonary complications.

Abstract
Splenic abscess is a rare condition. Haematogenous seeding to the spleen from an infection at a distant site, most often endocarditis, is been the most common predisposing condition but an increase has been observed in immuno-compromised patients too. Fever, leukocytosis and left upper quadrant pain are suggestive, but the signs and symptoms of splenic abscesses are often non-specific. Rare is the onset with diarrhoea as in our case. Ultrasound and computed tomography are reliable diagnostic tools. Splenectomy and antibiotics are the treatments of choice. We describe a case of splenic abscess with gas level and peritonitis from dissemination of Streptococcus anginosus (of Streptococcus millerii group) from duodenal ulcer contaminated. It was diagnosed with CT, ultrasound, and abdomen X-ray with contrast then treated with splenectomy and peritoneal lavage.

Abstract
The Authors highlight the efficacy of the Lauren's classification in 28 surgically treated gastric cancer patients. Lauren's classification allows a prognostic evaluation corresponding to the effective gastric cancer natural history. Present histo-morphological classification criteria appear not to coincide with the clinical evolution; as a matter of fact over- or understaging is possible in gastric cancer patients. 64,28% of the Lauren's classification intestinal type patients survive after a four year follow up vs. 42,85% of the diffuse type patients. The Authors discuss about new biomolecular knowledge in gastric cancer oncogenesis.

Abstract
The authors report the case of a patient affected by malignant melanoma and small cell lung cancer. After having underlined the rareness of this pathological association, reviewing the most recent literature, the description of the clinical case aims at opening a discussion on how the surgical treatment performed, associated to chemotherapy, brought to an unhoped-for success, also helped by an unexpected combination of events that were absolutely out of any protocol. Eleven years later, at the present follow-up, the patient shows a complete remission of both diseases.

Abstract
Plastic and oncological breast surgery are becoming more and more closer as one surgical treatment. The term "oncoplastic surgery" refers to the use of plastic surgery techniques in breast cancer surgery, in order to avoid and to correct the adverse aesthetic findings. The care of cosmetic sequelae of breast cancer surgery has reached an important therapeutic role for psychological consequences of disease and because of the higher patients expectations of a good aesthetic result. Considering the concept of oncoplastic surgery, since 1999 the Authors began to use a periareloar approach in the breast conserving therapy (BCT), associated to axillary dissection performed through the same periareolar incision. This technique, original from the oncological point of view, is not different from the traditional quadrantectomy in the extension of the glandular resection, while the skin may be preserved in according to the conventional protocols of BCT. Oncological and aesthetic results have proved to be safe and satisfactory.

Abstract
The reconstruction of the female breast after mastectomy has become a crucial part of primary breast cancer therapy. Setting of an implant is possible only in case of locally abounding soft tissue coverage and when no radiation has before performed. It is necessary a complete integrity of the submuscolar pocket and good blood supply of the skin to avoid failure of the procedure. In Author's experience, started since 1994, an immediate breast reconstruction after mastectomy is performed using gel-silicon implants directly when it was possible or setting first an expander. In six cases the condition of major pectoralis muscle after mastectomy was so foul that an immediate breast reconstruction with prosthesis was not realizable. However, the Authors tried a new technique using polypropylene mesh sutured on the major pectoralis muscle to cover the muscle partially destroyed. Preliminary data from the 6 pts seems to be encouraging.

Abstract
Axillary seroma is absolutely the most frequent complication of breast cancer surgery. The Authors have accrued 100 consecutive breast cancer patients in a randomized study in order to compare seroma incidence by removing drains on 2nd postoperative day (1st arm) versus 3rd postoperative day (2nd arm); 48 patients were accrued in the first arm and 52 in the second. All patients received a standard axillary dissection. Two suction drains were placed. A compressive medication was applied after surgery. Patients started physiotherapy on the 1st postoperative day. The overall seroma prevalence was 21%. We have 8/48 (16%) seromas in the 1st group and 13/52 (25%) in the 2nd. No significant differences were registered between two arms. Clinical seroma was treated by needle aspiration and medication with a steroid. Conclusions coming out from this study are: 1) early drains removal doesn't increase seroma rate; 2) axillary clearance has to be performed removing en bloc the fatty tissue respecting surgical plains; 3) apply a compressive bandaging; 4) early arm physiotherapy; 5) medication with steroid may reduce the fluid formation.

Abstract
During the past 15 years, surgery in Italy has undergone significant developments in health care services at the teaching and organizational levels. In 1987, the new teaching regulations of medical and surgical schools came into force with the introduction of integrated courses that converge into educational and training areas with precise objectives. For more than a decade, postgraduate schools have had a common guideline throughout the European community--becoming real "residencies." Surgical activity is provided by university hospital facilities and hospitals with a business administration that is completely autonomous as far as organization, income, management, technique, and accounts are concerned. Research guidelines for future developments are mainly addressed toward optimization of organization and use of the most recent technology. The widespread application of day surgery and video-assisted surgery substantiates this evolution of surgery in Italy.

Abstract
It has long been postulated that language is not purely learned, but arises from an interaction between environmental exposure and innate abilities. The innate component becomes more evident in rare situations in which the environment is markedly impoverished. The present study investigated the language production of a generation of deaf Nicaraguans who had not been exposed to a developed language. We examined the changing use of early linguistic structures (specifically, spatial modulations) in a sign language that has emerged since the Nicaraguan group first came together: In tinder two decades, sequential cohorts of learners systematized the grammar of this new sign language. We examined whether the systematicity being added to the language stems from children or adults: our results indicate that such changes originate in children aged 10 and younger Thus, sequential cohorts of interacting young children collectively: possess the capacity not only to learn, but also to create, language.
