Outcomes of a same day discharge protocol in patients undergoing mastectomy and implant reconstruction.

BACKGROUND: Finite hospital resources has required a closer look at resource allocation. This has prompted a shift toward same day surgeries and a focus on reducing hospital readmissions. Following the institution of a same day discharge protocol for mastectomy and mastectomy with immediate reconstruction, we sought to assess differences in the length of stay and readmission rates. METHODS: This retrospective review evaluates all cases of mastectomy with or without immediate reconstruction performed at a single high-volume center between June 2019 and March 2021. Average length of stay, 30-day readmission rates, Anesthesia Society Assessment class, and type of immediate reconstruction were assessed. Autologous reconstructions were excluded. RESULTS: A total of 413 patients underwent mastectomy with or without reconstruction (n = 148 pre protocol and n = 265 during protocol) between June 2019 and March 2021. Of those 413 patients, 180 underwent reconstruction (n = 62 pre protocol and n = 118 during protocol). The average length of stay after mastectomy following the implementation of the same day discharge protocol was decreased at 0.6 days (n = 265) compared to preimplementation at 1.02 days (n = 148), p < 0.001. The 30-day readmission rate was not significant between the groups, p = 0.13. A total of 180 patients underwent immediate reconstruction after mastectomy. The average length of stay after mastectomy with immediate reconstruction following implementation of the same day discharge protocol was shorter than preimplementation at 1.05 days preimplementation (n = 62) versus 0.58 days following implementation (n = 118), p < 0.001; this finding was significant for both prepectoral and subpectoral implants, p < 0.001. There was no significant difference in 30-day readmission rates between the groups with immediate reconstruction, p = 0.34. CONCLUSION: Same day discharge for mastectomy with reconstruction is as safe as the more widely recognized same day discharge practice for patients with mastectomy alone.

Classification of new morbillivirus and jeilongvirus sequences from bats sampled in Brazil and Malaysia.

As part of a broad One Health surveillance effort to detect novel viruses in wildlife and people, we report several paramyxovirus sequences sampled primarily from bats during 2013 and 2014 in Brazil and Malaysia, including seven from which we recovered full-length genomes. Of these, six represent the first full-length paramyxovirid genomes sequenced from the Americas, including two that are the first full-length bat morbillivirus genome sequences published to date. Our findings add to the vast number of viral sequences in public repositories, which have been increasing considerably in recent years due to the rising accessibility of metagenomics. Taxonomic classification of these sequences in the absence of phenotypic data has been a significant challenge, particularly in the subfamily Orthoparamyxovirinae, where the rate of discovery of novel sequences has been substantial. Using pairwise amino acid sequence classification (PAASC), we propose that five of these sequences belong to members of the genus Jeilongvirus and two belong to members of the genus Morbillivirus. We also highlight inconsistencies in the classification of Tupaia virus and Mòjiang virus using the same demarcation criteria and suggest reclassification of these viruses into new genera. Importantly, this study underscores the critical importance of sequence length in PAASC analysis as well as the importance of biological characteristics such as genome organization in the taxonomic classification of viral sequences.

Livestock rabies in Pará state, Brazil: a descriptive study (2004 to 2013) / Raiva em herbívoros no estado do Pará, Brasil: estudo descritivo (2004 a 2013)

Rabies is an important zoonosis to public health associated with lethal encephalitis and economic losses. Analysis of its spatial distribution is a meaningful tool in understanding its dispersion, which may contribute to the control and prophylaxis of the disease. This study analyzed the spatial-temporal distribution of rabies outbreaks in livestock in Pará state, Brazil, from 2004 to 2013. We used records of neurological syndromes obtained from the state's livestock authority (Adepará). The analysis recorded 711 neurological syndromes reports in livestock, of which 32.8% were positive for rabies. In 8% of the neurological syndromes (n=57) was not possible to perform the analysis because of bad-packaging conditions of the samples sent. Outbreaks involved at least 1,179 animals and cattle were the most affected animal species (76.8%). The numbers of reported neurological syndromes and of rabies outbreak shad strong positive correlation and exhibited decreasing linear trend. Spatially, most outbreaks occurred in two mesoregions in Pará (Northeast and Southeast). One of the justifications for this spatial distribution may be related with the distribution of the animals in the state, since these mesoregions are the largest cattle producers in Pará and have most of their territory deforested for pasture implementation.(AU)

A raiva é uma zoonose importante para a saúde pública associada à encefalite letal e às perdas econômicas. A análise de sua distribuição espacial é uma ferramenta importante no entendimento de sua dispersão, o que pode contribuir para o controle e a profilaxia da doença. Este estudo analisou a distribuição espaço-temporal do surto de raiva em rebanhos no estado do Pará, Brasil, entre 2004 e 2013. Foram utilizados registros de síndromes neurológicas obtidas junto à agência de defesa agropecuária do estado (Adepará). A análise revelou 711 notificações de síndromes neurológicas em herbívoros, das quais 32,8% foram positivas para raiva. Em 8% das síndromes neurológicas (n=57) não foi possível realizar as análises devido às más condições das amostras enviadas. Surtos envolveram pelo menos 1.179 animais e os bovinos foram a espécie animal mais afetada (76,8%). Os números de síndromes neurológicas relatadas e de surtos de raiva apresentam forte correlação positiva e exibem tendência linear decrescente. Espacialmente, a maioria dos surtos ocorreu em duas mesorregiões no Pará (Nordeste e Sudeste). Uma das justificativas para essa distribuição espacial pode estar relacionada à distribuição dos animais no estado, uma vez que essas mesorregiões são os maiores produtores de gado do Pará e possuem grande parte do seu território desflorestado para implantação de pastagens.(AU)

NEOSPORA CANINUM-SPECIFIC ANTIBODIES IN FREE-RANGING WHITE-LIPPED PECCARIES ( TAYASSU PECARI) FROM THE PERUVIAN AMAZON: DETECTION OF ANTIBODIES IN SERUM AND EVALUATION OF INDIRECT FLUORESCENT ANTIBODY TEST WITH HETEROLOGOUS SECONDARY ANTIBODY.

Neospora caninum is a coccidian parasite originally reported in dogs and widely prevalent in numerous species of wild and domestic animals and has as definitive hosts some species of canids. The white-lipped peccary (WLP) ( Tayassu pecari) is a Tayassuidae mammal, found from Mexico to south of Brazil and north of Argentina. It is a game species with great economic importance in the Peruvian Amazon. Blood samples from 101 WLPs were collected from near or within three different conservation reserves located in the southeastern region of the Peruvian Amazon. For the detection of antibodies against N. caninum, indirect fluorescent antibody tests (IFAT) were performed using collared peccary ( Pecari tajacu) and swine ( Sus scrofa domesticus) heterologous secondary antibodies. For both IFAT tests, the cutoff was 1:50. Positive samples were titrated by a two fold serial dilution. In addition to IFAT, samples were also analyzed using an immunoblotting test (IB) with anti-swine conjugate. To confirm the viability of the anti-swine conjugate, the results of these samples previously tested by a modified agglutination test (MAT) for Toxoplasma gondii were used as reference. From the total of 101 samples tested, 5 (4.9%) were N. caninum positive by the three tests and an extra sample was positive by both IFATs and negative in the IB. Comparing both IFATs and considering IB as the gold standard, the relative sensitivity of IFATs was 100%, the specificity was 98.9%, the positive predictive value was 83.3%, and the negative predictive value was 100%. The agreement between tests was characterized by a κ value of 0.904 (95% confidence interval, 0.717 to 1.0) and an SE of 0.095. This is the first report of N. caninum antibodies in free-ranging T. pecari, and swine and collared peccary conjugate can be used as a secondary antibody for detection of antibodies in Tayassu species.

Ticks (Acari: Ixodidae) of the state of Amazonas, Brazil.

The tick fauna of Brazil is currently composed by 72 species. The state of Amazonas is the largest of Brazil, with an area of ≈ 19% of the Brazilian land. Besides its vast geographic area, only 19 tick species have been reported for Amazonas. Herein, lots containing ticks from the state of Amazonas were examined in three major tick collections from Brazil. A total of 5933 tick specimens were examined and recorded, comprising 2693 males, 1247 females, 1509 nymphs, and 484 larvae. These ticks were identified into the following 22 species: Amblyomma cajennense sensu lato, Amblyomma calcaratum, Amblyomma coelebs, Amblyomma dissimile, Amblyomma dubitatum, Amblyomma geayi, Amblyomma goeldii, Amblyomma humerale, Amblyomma latepunctatun, Amblyomma longirostre, Amblyomma naponense, Amblyomma oblongoguttatum, Amblyomma ovale, Amblyomma rotundatum, Amblyomma scalpturatum, Amblyomma varium, Dermacentor nitens, Haemaphysalis juxtakochi, Ixodes cf. Ixodes fuscipes, Ixodes luciae, Rhipicephalus microplus, Rhipicephalus sanguineus sensu lato. Ticks were collected from 17 (27.4%) out of the 62 municipalities that currently compose the state of Amazonas. The following four species are reported for the first time in the state of Amazonas: A. coelebs, A. dubitatum, H. juxtakochi, and Ixodes cf. I. fuscipes. The only tick species previously reported for Amazonas and not found in the present study is Amblyomma parvum. This study provides a great expansion of geographical and host records of ticks for the state of Amazonas, which is now considered to have a tick fauna composed by 23 species. It is noteworthy that we report 1391 Amblyomma nymphs that were identified to 13 different species.

Toxoplasma gondii antibodies in wild white-lipped peccary (Tayassu pecari) from Peru.

In the Peruvian Amazon, the white-lipped peccary (Tayassu pecari) is a desirable game species and is important for the local rural economy. Blood samples from 101 white-lipped peccaries from Peru were collected from 3 different conservation areas located in the municipalities of Manu and Tambopata, southeastern region of the Peruvian Amazon. Antibodies were assayed using the modified agglutination test (MAT, cut of value of 25). Antibodies to Toxoplasma gondii were found in 89.1% (90 of 101) of animals, with titers of 1 ∶ 25 in 9, 1 ∶ 50 in 25, 1 ∶ 100 in 20, 1 ∶ 200 in 14, 1 ∶ 400 in 12, 1 ∶ 800 in 9, and 1 ∶ 3,200 in 1; 87.7% and 89.2% of males and females, respectively, tested positively, and no association (P ≥ 0.05) with gender and occurrence of antibodies was observed.
