“…If the treatment is not timely, it may lead to lifelong disability, leaving irreversible damage, and even endanger the life and health of patients [ 2 , 3 ]. Hemorrhagic hydrocephalus and neoplastic hydrocephalus are two common types of secondary hydrocephalus [ 3 , 4 ]. Early diagnosis of secondary hydrocephalus is of great significance to guide clinical treatment and improve the prognosis of patients [ 5 , 6 ].…”

Objectives. To investigate the value of cerebrospinal fluid chloride (CSF-Cl), cerebrospinal fluid glucose (CSF-GS), cerebrospinal fluid microalbumin (CSF-MALB), and cerebrospinal fluid adenosine deaminase (CSF-ADA) in the differential diagnosis of secondary hydrocephalus. Methods. 103 patients with secondary hydrocephalus treated in our hospital from January 2018 to April 2022 were selected. According to different types, it is divided into the hemorrhagic hydrocephalus group and tumor hydrocephalus group. By detecting the levels of inflammatory factors such as CSF-Cl, CSF-GS, CSF-MALB, and CSF-ADA in the two groups, we can analyze the value of these inflammatory factors in the differential diagnosis of secondary hydrocephalus. Results. The level of CSF-MALB in the hemorrhagic hydrocephalus group was significantly higher than that in the tumor hydrocephalus group, and the difference between the two groups was statistically significant ( P < 0.05 ). There was no significant difference in the levels of CSF-Cl, CSF-GS, and CSF-ADA between the two groups ( P > 0.05 ). The area under ROC curve (AUC) of CSF-Cl, CSF-GS, CSF-MALB, and CSF-ADA in the differential diagnosis of secondary hydrocephalus was 0.438, 0.553, 0.750, and 0.542, respectively, sensitivity was 15.1%, 45.3%, 79.2%, and 18.9%, respectively, and specificity was 96.0%, 80.0%, 80.0%, and 94.0%, respectively. Conclusions. The inflammatory reaction of hemorrhagic hydrocephalus was significantly greater than that of tumor hydrocephalus. Moreover, CSF-MALB is closely related to the pathogenesis of hemorrhagic hydrocephalus. At the same time, CSF-MALB can be used as a good index for rapid differential diagnosis of secondary hydrocephalus.

“…On the other hand, riparian vegetation areas keep a constant mild microclimate (Quintão et al, 2013;Rezende et al, 2017) compared to agricultural areas. High temperatures may accelerate the ecosystem metabolism by stimulating the decomposing community activity in rodents' carcasses (Navarro et al, 2013;Al-Mekhlafi et al, 2020;Probst et al, 2020). As an example, lower and constant soil temperatures may slow down the metabolic activity and oviposition of detritivorous insects, such as Diptera and Coleoptera, and as calliphorids (Souza & Linhares, 1997;Pujol-Luz et al, 2006).…”

“…The families Calliphoridae, Sarcophagidae, and Muscidae have a preference for colonizing soft tissues during the initial stages of decomposition (Cruise et al, 2018;Tembe & Mukaratirwa, 2021). Furthermore, small carcass decreases the resource available, concentrating the greatest insects' abundances in early stages of decomposition (Al-Mekhlafi et al, 2020;Zeariya & Kabadaia, 2019). Also, the presence of hymenoptera in rodent carcasses is common, especially species of Vespidae families (Haskell et al, 2008).…”

“…Also, some rodent carcasses in decomposition process may undergo skeletonization or mummification (Figure 4). Mummification is a drying process, dependent on extreme factors of temperature and humidity, which inhibits bacterial activity (Al-Mekhlafi et al, 2020;Tembe & Mukaratirwa, 2021). As an example, high temperatures and low humidity accelerate the decomposition of rodent carcasses, but cause the mummification of some carcasses (Al-Mekhlafi et al, 2020;Haskell et al, 2008).…”

We evaluated the insect succession in small rodent carcasses on the soil extracts (surface vs. buried) in two areas (riparian vs. agricultural) and two seasonal periods (spring vs. summer). Daily, the rodent carcasses were weighed and the insects present were collected in them for counting and family level identification. We also measured the air and soil temperature daily, in addition to the physical and chemical characteristics of the soil. The total of 11,059 individuals from 28 taxa was collected. The most abundant taxa were Calliphoridae (70%), Formicidae (20%), Muscidae (2%), and Sarcophagidae (2%). Insect richness was higher in spring in riparian vegetation areas; however, decomposition and insect abundance were greater in spring in agricultural areas by the high temperature measured. Vespidae, Sarcophagidae, Muscidae, and Calliphoridae decreased over time with abundance peaks respectively at 3, 7, 7, and 8 days in riparian vegetation areas. Calliphoridae decreased abundance over time with a peak at five days, but Armadillidiidae increased with peak at 6-9 days in agricultural areas. Decay and insect abundance was high in agricultural areas, mainly on the soil surface. Insect richness was high in riparian vegetation areas, especially on the soil surface. Only the superficial layers of soil presented taxon indicators and all decreased over time with abundance peaks of Calliphoridae, Sarcophagidae, and Muscidae at 5-8, 7, and 7 days, respectively. This abundance peak of insect families help to understand the degradative succession of the insect community in small rodents in subtropical systems of the neotropical region.

The decomposition of animal remains is a multifaceted process, involving ecological, biological, and chemical interactions. While the complexity is acknowledged through concepts like the necrobiome, it’s unclear if this complexity is reflected in research. Appreciation of the complexity of decomposition is crucial for identifying sources of variation in estimations of time since death in medico-legal science, as well as building broader ecological knowledge of the decomposition process. To gain insights into the extent of multidisciplinary research in the field of decomposition science, we conducted an examination of peer-reviewed literature on four key drivers of variation: volatile organic compounds, microbes, drugs/toxins, and insects. Among 650 articles, we identified their scientific discipline, driver/s of variation investigated, and year of publication. We found that 19% explored relationships between two drivers, while only 4% investigated interactions between three. None considered all four drivers. Over the past three decades, there has been a steady increase in decomposition research publications, signifying its growing importance. Most research (79%) was linked to forensic science, highlighting opportunities for interdisciplinary collaboration in decomposition science. Overall, our review underscores the need to incorporate multidisciplinary approaches and theory into contemporary decomposition research.
